Longer Wear LifeU.S. Tsubaki Roller Chain lasts up totwice as long as our previous chain inmany applications. Advanced technologyallows us to combine the strength,durability, and reliability of a solid bushingwith our patented lube groove on theinner surface of sizes RS80 throughRS140. The solid bushings are preciseround cylinders, which means bettercontact between the pin and bushing. Thelube grooves hold oil where chain needsit most. The result is longer lasting chain.

Wear Elongation Curve

Save Time & MoneyWear in the pin-bushing joint can lead to elongation and replacement. U.S. Tsubaki’sASME/ANSI Chains have a patented lube groove that holds lubricant right where it’sneeded — in the pin-bushing joint. Tsubaki chains last longer, reducing maintenance,operating, and replacement costs.

Higher Horsepower RatingsU.S. Tsubaki ASME/ANSI Chains handleup to 33 percent more horsepower so youcan increase drive performance withoutincreasing chain size. In fact, dependingon your application, you may be able totransmit the same horsepower with asmaller, less costly chain. Theimprovement comes from a U.S. Tsubakiexclusive ring coining process for the slipfit connecting link and special processingon the two-pitch offset link.

Greater Fatigue StrengthU.S. Tsubaki ASME/ANSI Chains aredesigned to have higher fatigue strength.The wider waist of the link plates putsmore metal where you need it — runningyour application. There is less downtimebecause chains operate longer. Operatingcosts are reduced because chainsperform more efficiently. These benefitsgo right to your bottom line.

Assurance of Greater Fatigue StrengthThe wider waist of U.S. Tsubaki linkplates ensures greater fatigue strength forall chain sizes. Fatigue strength (max.allowable load) of each size can be foundin this catalog.

Shot Peened PartsLink plates and rollers are shot peenedfor greater fatigue strength.

Factory PreloadingU.S. Tsubaki roller chains are continuouslypreloaded on multi-sprockets after finalassembly as shown below. This results inminimum initial stretch.

Heat Treatment Ensures DurabilityChain durability depends to a great extenton the heat-treatment of the variousparts. The use of the most advancedheat-treatment methods and equipmentguarantees that U.S. Tsubaki roller chainsare highly durable.

PrelubricationA special lubrication is applied by U.S.Tsubaki to bearing surfaces by hotdipping to extend chain life and reducemaintenance costs.

A Completely AutomatedManufacturing ProcessThe manufacture of U.S. Tsubaki rollerchains employs advanced, automatedtechniques. The specialized equipmentused in each process ensures that allparts are uniform and high quality. Thephoto below shows the automatedpositioning of curled bushings.

Longer Wear Life & Less InitialAdjustment1) U.S. Tsubaki has decreased initial

wear elongation to 0.01% andincreased wear life by up to twice as long in many applications. Whereinitial elongation is a problem, as inprecision applications or when yousimply demand the best, U.S. Tsubakiroller chain is the solution.

2) Our original prelubricant minimizeswear elongation to enable a vastincrease in the chain's wear life.

3) U.S. Tsubaki’s lube groove bushingshold oil at the pin-bushing interface,extending the working life of the chain.

4) Micron control has enabled U.S.Tsubaki to produce perfectly straightbushings and significantly reduce wearelongation during initial operation.

5) Improved U.S. Tsubaki roller chainsizes RS80 through RS140 have thepatented PerforMax™ solid lubegroove bushings and last up to twice as long in many applications. The lubegroove retains oil at the critical pin-bushing contact point, extending thelife of the chain.

S Roller chains can be operated at speeds of up to 10,000 rpm. Even at high speeds, chain drive is quieterand smoother than a gear drive. You never have to worry about slippage as you would with a belt.

Roller chains are inherently elastic. Compared with gear drives, they soften shock and absorb vibration.They can be used in machines which are subjected to great shock or which constantly move or vibrate.Both the machine's body and bearing parts are protected against damage.

CONNECTION OF RS ROLLER CHAIN – IMPROVED

Roller chain is normally used as a continuous length witha connecting link, resulting in an even number of pitches.

Connecting LinksStandard connecting links are used when RS roller chain isoperated under normal conditions. For severe applications,press fit connecting links are suggested. In either case, aspring clip connecting link is used for RS roller chains of sizesRS60 or smaller, a cottered connecting link for sizes RS80 toRS200, and a spring pin connecting link for RS240. Acottered type connecting link is used for three to six strands ofRS40 to RS60. A cottered type can be provided for single anddouble strands of RS40 to RS60 upon request.

Standard connecting links have a slip fit cover plate.

The wider waist of U.S. Tsubaki's cover plates provides higherfatigue strength.

Installation of press fit connecting links may be less convenientthan that of standard connecting links, but performance isbetter. Press fit connecting links should be used in extremelyhigh-speed or heavy duty applications.

The slip fit connecting links on improved U.S. Tsubaki chainhave 25% greater fatigue strength. These connecting links arering coined, which means improved capacity for yourapplication.

Roller ChainA roller chain consists of roller links and pinlinks connected in series.

If a continuous length has an odd number of pitches, anoffset link must be used. However, the use of offset linksshould be avoided.

Offset LinksBoth two-pitch offset links and one-pitch offset links areavailable for RS roller chains. U.S. Tsubaki's redesigned linkplate and improved manufacturing process make our two-pitchoffset links stronger than ever.

The two-pitch offset link is a combination of a roller link and anoffset link connected with a riveted pin. The connecting linkcan be attached to either side of a two-pitch offset link.

One-pitch offset links are very handy, but pin and offset linkplates have to be slip-fitted. One-pitch offset links are alsoweaker than plain chain and two-pitch offset links. Therefore,one-pitch offset links are not suggested, especially for frequenton-and-off operation, heavy impact loads, and high-speeddriving.

Note: Only two-pitch offset links are available for RS25.

Heavy SeriesHeavy Series roller chains differ from the ASME/ANSI standard series in the extra thickness of thelink plates and the extra length of the pins. These link plates have the same thickness as the linkplates of ASME/ANSI chains having the next larger pitch. The thicker link plates provide greatercapacity (approximately 10%) for absorbing shock loads. These chains are suitable in situationswhere the load is heavy or operating conditions are severe.

2) Use Table I to obtain the “Service Factor.”3) Multiply the horsepower value by the service

factor to obtain the design horsepowervalue.

4) Use Table IV on page A-24 and thehorsepower ratings tables on pages A-6 toA-19 to obtain the appropriate chain numberand the number of teeth for small sprockets.Refer to the number of revolutions of thehigh speed shaft (the driving shaft when thespeed is reduced; the driven shaft when thespeed is increased) and the designhorsepower value. For smoother chain drive,a smaller pitch chain is suggested. If asingle strand chain does not satisfy thetransmission requirements, use a multiplestrand chain. If there are space limitations, amultiple strand roller chain with a smallerpitch may be used.

5) After determining the number of teethnecessary for the small sprocket, refer to theSprocket Dimension Table (pages A-79 to A-82) to check if the sprocket diametersatisfies the space limitations.

6) The number of teeth for the large sprocket isdetermined by multiplying the number ofteeth for the small sprocket by the speedratio. More than 15 teeth on the smallsprocket is suggested. The number of teethfor the large sprocket should be less than120. By reducing the number of teeth for thesmall sprocket, the number of teeth for thelarge sprocket can be reduced.

7) For temperatures below 15°F, see theEnvironmental Temperatures and Points ofConcern Table on page B-38.

CHAIN DRIVE SELECTION

Horsepower RatingThe horsepower rating in Table IV on page A-24 is based on the following conditions:1) The chains are operated under ordinary

conditions. The ambient temperature rangemust be between 15°F and 140°F. Theyshould not be used in an atmosphere inwhich abrasive dust or corrosive gas ispresent or where the humidity is high.

2) The two transmission shafts are in ahorizontal position, and the chains areproperly installed.

3) The suggested lubrication system and oil areused.

4) The load does not change significantly duringtransmission. The “Service Factor” given inTable I should be taken into account whenthe chains are used under various operatingconditions. The load conditions will affect thelife of the chain.

5) The increase in the horsepower rating ofmultiple strand roller chain cannot becalculated simply by multiplying thehorsepower rating of one strand by thenumber of strands, since the load on eachstrand is not exactly the same. In order toestimate the service life of a multiple strandchain, the “Multiple Strand Factor” given inTable II must be used. When the chain lengthis 100 pitches and the above conditions aremet, a service life of approximately 15,000hours can be expected.

Procedures for Selecting Roller Chain1) The following factors must be considered

when selecting roller chain.a. Source of powerb. Driven machinec. Horsepower to be transmittedd. RPM of driving and driven shaftse. Diameter of driving and driven shaftsf. Center distance of the shafts

inches. The horsepower rating of a 15-tooth sprocket for the RS60-3 shouldbe confirmed by the horsepower ratingfor the RS60 (see page A-11).

The horsepower rating of a 15 toothsprocket is 15.1 hp at 700 rpm and 17hp at 800 rpm. So the horsepowerrating at 750 rpm is about 16 hp. Since16 hp is for a single strand chain, thehorsepower rating must be multipliedby a multiple strand factor of 2.5 for atriple strand (see page A-22).

Therefore, the horsepower rating ofRS60-3, 15 teeth at 750 rpm is 40 hp(16 • 2.5 = 40).

Step 5 Refer to Sprocket Section (C)in this catalog to check the diameter ofthe bore.

A 45-tooth sprocket meets the necessaryrequirement, but since the maximum borediameter (1.87 inches) of a 15-toothsprocket is smaller than the drive shaftdiameter of 2 inches, it can’t be used.

A 16-tooth sprocket with a maximum borediameter of 2 inches must be used.Check again that the outside diameter,4.21 inches for 16 teeth and 11.89 inchesfor 48 teeth, is less than the spacelimitation (4.21 + 11.89 < 20).

A combination of RS60-3, 16 and 48teeth must be used to fulfill all thenecessary requirements.

Selection for Slow Speed

When the chain speed (S) is less than 160 ft./min., select the RS roller chain that is one size smaller than the chain chosen from the horsepower rating method mentioned above.

1. Tentatively select the chain andsprocket from Table IV (page A-24)and proceed by using a one-size-smaller chain and its sprocket with thenumber of teeth close to the sprocketselected above. Be sure to confirmthat the sprocket meets the applicationrequirements such as bore diameterand space limitation, etc.

2. Calculate the chain speed from thenumber of teeth on the drivingsprocket using equation (A). Alsocheck that the speed is less than 160ft./min.

3. Calculate the chain tension for theabove drive from equation (B).

4. Select the service factor and the chainspeed coefficient from Table I (page A-22)and Table III.

5. Verify that the chain has maximumallowable load which satisfiesequation (C).

There are two different ways to do thenext step: to increase the number ofteeth, or to use the same procedure forSuper Chains of the same size (refer toSuper Chains on pages A-35 to A-42).

Note: Please use press fit connectinglinks for slow speed chain selection.

Selection for High TemperaturesU.S. Tsubaki Improved Drive Chainsare made of heat treated carbon steel.When exposed to high temperatures,the mechanical properties of the heattreated chain components are lost.

1. The hardness, and therefore thewear resistance of pins andbushings, is reduced.

2. At temperatures above 390°F, therollers and plates lose their hardnessand strength.

5. Drive shaft:Diameter 2 inches, 750 rpmDriven shaft:Diameter 3 inches, 250 rpm

Step 2 Use Table I to determine theservice factor.

Service Factor SF = 1.0

Step 3 Obtain Design HPDesign HP = (HP to be transmitted) • SF

= 40 hp • 1.0= 40 hp

Step 4 Obtain the chain number andthe number of teeth on the smallsprocket from the Roller ChainSelection Table (page A-24) referringto the above 40 hp and 750 rpm.

Then check it by referring to the Horse-power Rating Tables (pages A-6 to A-19).

1. According to the horsepower rating,the best choice would normally be asingle strand of RS80-17 teeth. Sincethe speed ratio is 1/3 (250/750 rpm),the necessary number of sprocketteeth would be 17 for the smallsprocket and 51 for the large sprocket.But, as the outside diameters are 5.94inches for 17 teeth and 16.81 inchesfor 51 teeth (refer to sprocketdimensions on pages A-79 to A-82), itexceeds the space limitation of 20inches (5.94 + 16.81 > 20 inches).

Therefore, these sprockets are notsuitable.

2. As a single strand chain is notsuitable, a multiple-strand RS60-2, 22and 66 teeth would be possible. Butthis combination is not suitable due tothe space limitation again (5.67 +16.18 > 20 inches).

3. For triple strand, RS60-3, 15 and 45teeth would be possible.

The sprockets’ diameters are 3.90inches and 11.18 inches respectively,the sum of which is less than 20

How to use this table:1. Example ... Design horsepower — 7 hp

a) Assume that the RPM of the small sprocket is 100.Judging from the intersection point of the design horsepower’s value of 7 hp and the RPM value of 100, RS80 and a sprocketwith either 17 teeth or 18 teeth can be selected. Sprockets with 17 teeth are more economical than those with 18 teeth.

b) Assume that the RPM of the small sprocket is 300. An RS60, 15-tooth sprocket is appropriate from the intersection point in the same manner as above. The line for RS50-24 teeth can also be seen near the intersection of 7 hp and 300 rpm.Therefore, either RS60-15 teeth or RS50-24 teeth can be selected. This table is used to make a tentative selection. TheHorsepower Rating Tables should be used to determine the most appropriate chain and sprocket.

2. Horsepower lines of 20, 24 and 30-tooth sprockets are shown only in the high speed range on the right hand side of the abovechart. When checking the horsepower line of these sprockets, make a line parallel to the other lines on the left hand side of thedotted line for RS50-24 teeth.

3. When using a chain in the white part on the right side of the table, please consult with U.S. Tsubaki.4. When the chain speed is less than 160 ft./min., it is more economical to select your RS roller chain by the selection method for

slow speed drives (see page A-23).

Super ChainProven Performance

ASME/ANSI standard roller chains are widely used invarious industries. To meet the insistent demands of heavyindustry, construction and agriculture, stronger and higherperforming chains which can replace the correspondingASME/ANSI standard chains are necessary. U.S. Tsubakioffers a line-up of Super and Ultra Super Chains which willsolve your specific driving and conveying problems relatingto heavy shock load and/or space limitations.

SUPER ROLLER CHAIN SUPER 80 ˜ 240High fatigue and tensile strength allow the selection of a chain one size smaller than wouldbe required with standard chain.

Pins constructed of “high toughness”steel give this chain exceptional abilityto absorb shock loads.

The link plate holes are ball drifted toobtain high fatigue strength.

If you have a problem like breakage of pins due to heavy shock loads, we suggest that you use either the T Series or theHT Series.

If you have problems such as fatigue breakage of link plates, generally poor performance, or a space limitation, we suggestthat you use the Super Series, Super-H Series or Ultra Super Series. You may be able to use the next smaller size chain oreven a chain two sizes smaller.

T SeriesT Series chains have greater shock load resistance and higher ultimate tensile strength than comparable ASME/ANSI standardroller chains. This is accomplished by using thru hardened pins. The dimensions of the chains are identical to ASME/ANSI standardroller chains.

HT SeriesHT Series chains have a greater ultimate tensile strength (plus 15-30%) than ASME/ANSI standard roller chains by using thruhardened pins and link plates of the next larger chain size. These chains also provide greater shock load resistance. The dimensionsof the chains are identical to those of the ASME/ANSI Heavy Series standard roller chains.

Super SeriesThe dimensions of Super Series Chain are identical to those of ASME/ANSI standard roller chain. Super Series Chain has a widerwaist link plate than our standard chain and special manufacturing techniques are used to produce the pitch holes. After heattreatment, the holes are then ball drifted for greater fatigue strength. The pins are thru hardened for greater shock resistance.Because of this, Super Series Chain has a Maximum Allowable Load 25-30% higher than our standard RS roller chain.

Super-H SeriesSuper-H Series Chain has the same wide waist as Super Series. The link plate thickness is identical to those of the ASME/ANSIHeavy Series roller chains. The same special manufacturing techniques used in Super Series Chain are used to produce the pitchholes. The pins are thru hardened. Because of this, Super-H Series Chain has an even higher Maximum Allowable Load than theSuper Series.

Ultra Super SeriesU.S. Tsubaki Ultra Super Series has a greater ultimate tensile strength and allowable load than any other roller chain wemanufacture. With the Ultra Super Series, a chain up to two sizes smaller than standard can be selected.

Chain Drive SelectionGenerally, Super Series chains aresuggested when the chain speed is lessthan 160 ft./min. and where the RS rollerchain or the ASME/ANSI Heavy Seriesare not strong enough to meet theapplication requirements.1)Tentatively select the chain and

sprocket with the same size and numberof teeth as used in “Selection for SlowSpeed” on page A-23.

2)Calculate the chain speed from thenumber of teeth of the driving sprocketusing equation (A) and check whetherthe speed is less than 160 ft./min.

3)Calculate the chain tension necessaryfor the above drive from equation (B).

4)Select the service factor and the chainspeed coefficient from Tables I and II.

5)Select the suitable chain and verify thatthe chain satisfies equation (C).

For details, refer to Table I on page A-22.

The following three lubricating systems are suggested:

System A

System B

System C

Manual lubricationThe oil is applied with an oil can or brushin the gap between the pin and roller linkon the slack side of the chain. It shouldbe applied about every eight hours or asoften as necessary to prevent thebearing areas from becoming dry.Suitable chain speed is to be below 50ft./min.

Drip lubricationA simple casing can be used. The oil issupplied by a drip feed. Each strand ofchain should ordinarily receive 5 to 20drops of oil per minute. The amount isincreased as the speed increases.Suitable chain speed is from 50 to 100ft./min.

Oil bath lubricationThe chain is installed in a leak-freecasing. The oil depth of “h” should be 1/4to 1/2 inch deep. If the oil is too deep, itwill be adversely affected by the heatgenerated. Suitable chain speed is from100 to 160 ft./min.

SELECTION PROCEDURE

1) The following factors must beconsidered when selecting rollerchains for transmission needs.• The power to be transmitted.• The speed and the diameters of the

driving shaft and the driven shaft.• The distance between the centers of

the shafts.

2) Use Table I to obtain the servicefactor. (The “Service Factor” tablerefers to the type of machine andsource of power.)

3) Multiply the HP value by the servicefactor to obtain the design HP value.

4) Use Table III page A-52 to obtain theappropriate chain number and thenumber of teeth for the small sprocketby referring to the number ofrevolutions of the high speed shaft(the driving shaft when the speed isreduced; the driven shaft when thespeed is increased) and the designHP value. For a smoother chain drive,a smaller pitch chain is suggested. If asingle strand chain does not satisfythe transmission requirements, use amulti-strand chain. If the distancebetween the shafts and the diameterof the sprockets must be relativelysmall due to space considerations, amultiple strand roller chain with asmaller pitch may be used.

5) After determining the number of teethfor the small sprockets, confirm if thesprocket will meet the shaft diameterrequirements.

6) The number of teeth for the largesprocket is determined by multiplyingthe number of teeth for the smallsprocket by the speed ratio. While it ispreferable that the number of teeth forthe small sprocket be greater than 15,it is suggested that the number ofteeth for the large sprocket not exceed120. By reducing the number of teethfor the small sprocket, the number ofteeth for the large sprocket can alsobe reduced.

The selection table is based on the followingconditions:1) The chains are operated under ordinary

conditions. The ambient temperaturerange is between 15°F and 140°F. Theyare not to be used in an atmospherewhere abrasive dust or corrosive gas ispresent or when the humidity isexceptionally high.

2) The two transmission shafts are in ahorizontal position and the chains areproperly installed.

3) The suggested lubrication system shownon Table IV is used.

4) The load does not change significantlyduring transmission.The “Service Factors” given in Table I areused when the chains are used undervarious operating conditions. The loadconditions will affect the life of the chain.The increase in the horsepower rating ofmultiple-strand roller chains cannot becalculated simply by multiplying thehorsepower rating of one strand by thetotal number of strands, since the load oneach strand is not exactly the same. Inorder to estimate the service life of amultiple-strand chain, the “Multiple-StrandFactor” given in Table II must be used.

Note: Refer to page A-77 for details of lubrication system.

Example

Data:1. Type of application: Centrifugal Blowers2. Source of power: Electric Motor3. HP to be transmitted: 40 hp4. Driving shaft: 600 rpm5. Driven shaft: 200 rpm6. Center distance: 19 inches7. Space limit: Max. 24 inches

Step 1 Use Table I and determine theservice factor.Service factor (SF): 1.0Step 2 Obtain design HPDesign HP= HP to be transmitted • SF

= 40 hp • 1.0= 40 hp

Step 3 Obtain the chain size and thenumber of teeth of the small sprocket fromthe selection table for 40 hp and 600 rpm.

According to the selection table, the selectedchain and sprocket rpms are:(a) RS12B-3 chain and 25-tooth sprocket(b) RS16B-2 chain and 17-tooth sprocket(c) RS16B-1 chain and 25-tooth sprocket

* For (a), the necessary number of teeth forboth small and large sprockets are 25 teethand 75 teeth respectively, since the speedratio is 1/3 (200/600 rpm). But the outsidediameter of both sprockets, 6.3 inches for 25teeth and 18.3 inches for 75 teeth, exceedsthe limitation (6.3 inches + 18.3 inches > 24inches). Therefore, these sprockets cannot beinstalled.

* For (c), the necessary number of teeth forboth small and large sprockets are 25 teeth(outside dia. 8.4 inches) and 75 teeth (outsidedia. 24.4 inches), respectively. It exceeds thespace limitation again (8.4 inches + 24.4inches > 24 inches).

* For (b), the necessary number of teeth forboth the small and large sprockets are 17(outside dia: 5.9 inches) and 51 (outside dia:16.8 inches). It satisfies the space limitation(5.9 inches + 16.8 inches < 24 inches). Acombination of RS16B-2, and 17 teeth and51 teeth must be used to fulfill all thenecessary requirements.

Step 4 Use Table IV to determine thelubrication method.

Chain speed (S) = P • N • n12

= 1 • 600 • 17 = 850 ft./min.12

System B is suggested.Step 5 Obtain the number of pitches ofchain (L).

Anti-CorrosiveHeat ResistantChainNEPTUNE® CHAINNEPTUNE® chain resists corrosion when exposed to harsh outdoor environments, including seawater. The exclusive NEPTUNEsurface treatment process gives the chain its unique matte grey color and provides a protective finish that is more corrosion resistantthan Nickel-Plated chains. NEPTUNE chain has the same high maximum allowable load as our standard carbon steel roller chain.

NICKEL-PLATED CHAINNickel-Plated chains provide acceptable performance where equipment must operate in mildly corrosive environments.

600 AS SERIESAS Series chains are an excellent choice for drives requiring both corrosion resistance and high load capacity. Link plates are made of304 stainless steel and the round parts are made of hardened 600 series stainless steel. Of all the stainless steel chains offered byU.S. Tsubaki, AS Series has the highest load capacity. Use where stainless steel is required by FDA regulations.

304 SS SERIESSS Series chains are made completely of 304 stainless steel. SS Series has an excellent resistance to corrosion & temperatureextremes. It is generally considered non-magnetic, although some permeability can be found in these chains. This is caused by thecold working of the components during the manufacturing process. If more complete non-magnetic permeability is required, wesuggest our NS Series.

316 NS SERIESNS Series chains are made completely of 316 stainless steel. It is the most corrosion resistant standard stainless steel chain offeredby U.S. Tsubaki. It also has the highest resistance to temperature extremes, and is sometimes referred to as our non-magnetic seriesbecause of its extremely low magnetic permeability. The load capacity of 316 NS Series is equal to that of our 304 SS Series.

POLY-STEEL CHAINPoly-Steel chain is made of molded engineered plastic with 304 stainless steel pin links. This combination effectively incorporates theadvantages of both materials into one chain. Poly-Steel chain from U.S. Tsubaki has superior wear life, excellent corrosion resistance,and requires no lubrication. This design provides a quiet, lightweight chain for economical solutions to difficult application problems.

TITANIUM TI SERIESTI Series chains are made completely of Titanium. Available in sizes RS35TI - RS60TI, TI Series brings the unique properties ofTitanium to roller chain applications, specifically extreme corrosion resistance in a lightweight chain. Available on a made-to-orderbasis in the same dimensions as the 304 SS Series. Call U.S. Tsubaki for further details.

� Additional Information1. Offset links are not available. Please use an even number

of links.

2. Existing RS standard sprockets can be used.

3. RF40PC to RF60PC use the same connecting links asstainless steel chain. RF25PC and RF35PC use specialconnecting links.

4. When replacing stainless steel chain with Poly-Steel chain,please check the chain tension. Chain tension should beless than the maximum allowable tension.

5. Ambient temperature range: -14°F ~ 176°F(-10°C ~ 80°C)

6. Maximum chain speed: less than 230 ft./min.

7. Coefficient of sliding friction between chain and guide railis 0.25 (without lubrication).

8. The guide rail should support the bottom side of the links.

9. The color of the inner links is WHITE.

� Connecting and Disconnecting1. Disconnect as follows:

As shown in the drawing, place the pin link plate on the jigand press down on the pin heads. Please be careful not toapply too much pressure to the plastic portion as there isthe possibility of breakage.

2. Please inquire about our disconnecting jig.

3. For connecting, please use a connecting link.

Leaf Chain

Leaf chains generally have greater tensile strength thanroller chains, and run over sheaves rather than sprockets.They are most often used as counterweight chains formachine tools, elevator and oven doors, fork lift truck masts,spinning frames and similar lifting or balancing applications.BL series can, in most instances, replace the older AL seriesLeaf chains; consult U.S. Tsubaki for interchangeinformation.

These chains are supplied with male or female terminationsto allow addition of various clevises as desired.

• For odd numbers of pitches inner links at both ends will be provided as standard.

• For even numbers of pitches a clevis connector or press fit and rivet outer link can be furnished.

• Clevis connector or press fit and rivet outer links are both available from stock in popular sizes.

Connection with Clevis:

1. When an inner link is used for the end, a clevis pin is normally supplied by the clevis manufacturer.

2. When an outer link is used for the end, the press fit outer link provides the most integrity.

GENERAL CAUTIONS1. Use lengths of factory assembled chain. Do not build lengths from individual components.

2. Do not attempt to rework damaged chains by replacing only the components obviously faulty. The entire chain may be compromised and should be discarded.

3. Never electroplate assembled Leaf chain or its components. Plating could result in failurefrom hydrogen embrittlement.

4. Welding should not be performed on any chain or component. Welding spatter should neverbe allowed to come in contact with chain or components.

5. Leaf chains are manufactured exclusively from heat treated steels and, therefore, must not beannealed. If heating a chain with a cutting torch is absolutely necessary for removal, thechain should not be reused.

6. Joining chains together should only be done by the chain manufacturer.

7. The Minimum Ultimate Strength of a chain means the minimum load at which it will breakwhen subjected to a destructive tensile test. It does not mean working load.

8. Chains from different manufacturers should not be used in the same application.

Lube-Free Chain

FX Chain

For use where normal lubrication is not practical, i.e., food processing equipment, packaging machines, printing and binding equipment, and textile machines.High quality lubricant is impregnated into the sintered metal bushings. Joint movement between the pin and bushing releases the necessary volume of oil to the pin surface and other parts, thereby minimizing chain elongation and eliminating the risk of chain seizure from insufficient lubrication.See our Drive Series LAMBDA® (page A-25) and Conveyor Series LAMBDA chains(page B-11) for additional specifications on other lube-free chains.

FX CHAINSU.S. Tsubaki FX chains feature excellentdurability and flexibility for tough applicationssuch as in concrete mixers, earth movingequipment, and mining machines.1. FX chains are interchangeable with

ASME/ANSI standard chains and canoperate on the same ASME/ANSI standard sprocket.

2. Increased clearance between pins andbushings allows the chains to accommodatea 4 inch lateral side bow and an 8 degreetwist per 4 feet of chain.

INSTALLATION AND ARRANGEMENT

Speed Ratio and Chain Wrap

The speed ratio of the roller chain canrange up to 7:1 under normal operatingconditions. However, a speed ratio of 10:1is possible if the speed is very slow. Chainwrap on the small sprocket must be at least120 degrees.

Distance Between Shafts

Sprockets can be separated by anydistance as long as their teeth do not touch.Optimum distance is 30 to 50 times thepitch of the chain used except when there isa pulsating load. In such cases, thedistance should be up to 20 times the pitchof the chain used.

Position

Roller chains are ideally installedhorizontally. When chains are installed atangles approaching the vertical, theystretch quickly and may slip off thesprockets. In such cases the sprocketsshould be adjusted properly.

Slack

Generally, the slack of a roller chain shouldbe on the lower side (see Fig. A). Adequateslack (SS’) is 4% of the span for normaldrives. In the following cases, the slackshould be about 2% of the span.a. Vertical drive or close to vertical drive.b. Center distance between two shafts is

greater than 3 ft.c. Chain is operated under heavy load and

high frequency of on and off drive.d. Direction of the drive is often changed.

Position of Sprocket

The two shafts should be parallel andpreferably in a horizontal position.Sprockets should be firmly installed.(See Figs. B and C)Use a straight edge to check that the twosprockets are installed along the samehorizontal plane.

ArrangementWhen designing roller chain drives, thecenterline of both sprockets should be closeto horizontal (see Figs. D and E). The angleof inclination can be up to 60 degrees asshown in Figs. F and G.If installation is close to vertical, it isdesirable to install an idler or a guidestopper to maintain smooth engagement ofthe chain and sprocket.

Attention should be paid to the followingarrangements.If the slack side is on the top, it isnecessary to eliminate excessive chainslack.

A-1. When the center distance is short,chain slack should be adjusted byincreasing the center distance.

A-2. When the center distance is long,chain slack should be adjusted by installingan idler.

B. If vibration occurs due to high chainspeed, install a guide.

C. If the centerline is vertical, install anidler which functions automatically toeliminate extra chain slack. If the drivingshaft is on the lower side, an idler must beinstalled.

LUBRICATION

S Lubrication Increases theService LifeOne of the most important factors in gettingthe best possible performance out of yourroller chain is proper lubrication. No matterhow well a transmission system isdesigned, if it is not properly lubricated, itsservice life will be shortened.

LubricationWear between the pin and bushing causesthe roller chain to stretch. These partsshould, therefore, be well lubricated. Thegap between the pin link plate and the rollerlink plate on the slack side of the chainshould be filled with oil. This oil forms a filmwhich minimizes wear on the pin andbushing, thus increasing the chain’s servicelife. It also reduces noise and acts as acoolant when the chain runs at highspeeds.

Suggested LubricantsOnly high quality oil should be used tolubricate the roller chain. Neither heavy oilnor grease is suitable. The viscosity of theoil used will depend on the chain size, chainspeed and ambient temperature. Thelubricants suggested for specifictemperature ranges are given in thefollowing table.

The following three lubricating systems are suggested:

Manual LubricationOil is applied with an oil filler or brush in the gapbetween the pin link and roller link on the slack sideof the chain. It should be applied about every eighthours or as often as necessary to prevent the bearingarea of the chain from becoming dry.Always turn off & lockout the power switch beforelubricating or servicing a chain system.

Drip LubricationA simple casing can be used. The oil is supplied bydrip feed. Each strand of chain should ordinarilyreceive 5 to 20 drops of oil per minute, according toincreases in the chain speed.

Oil Bath LubricationThe chain is installed in a leak-free casing. The oildepth “h” should be 1/4 to 1/2 inch deep. If the oil istoo deep, the oil will be adversely affected by the heatgenerated.

Lubrication by Slinger DiscInstall the slinger disc in a leak-free oil casing. Oil issplashed on the chain. The circumferential speedshould be at least 700 ft./min. If the width of the chainis greater than 5 inches, attach slinger discs to bothsides. The oil depth of “h” should be from 1/2 to 1inch deep. The chain should not pass through the oil.

Lubrication Using a PumpUse a leak-free casing. A pump is used to circulatethe oil which is then cooled.The number of supply holes should equal Z+1 whereZ is the number of strands of chain. The amount of oilsupplied to each hole is constant.

Regardless of the lubricating system used, the roller chain must be washed periodically withpetroleum or gasoline. Examine the pin and bushing after removing the chain. Any damage orreddish-brown color on their surfaces indicate that the system is not being adequately lubricated.

USE CARE TO PREVENT INJURYCOMPLY WITH FOLLOWING TO AVOID

SERIOUS PERSONAL INJURY:1. Guards must be provided on all chain and sprocket installations in accordance with provisions of

ANSI/ASME B15.1 — 2000 “Safety Standards for Mechanical Power Transmission Apparatus,”and ANSI/ASME B20.1 — 2006 “Safety Standards for Conveyors and Related Equipment,” orother applicable safety standards. When revisions of these standards are published, the updatededition shall apply.

2. Always lock out the power switch before installing, removing, lubricating or servicing a chainsystem.

3. When connecting or disconnecting chain:a. Eye protection is required. Wear safety glasses, protective clothing, gloves and safety shoes.b. Support the chain to prevent uncontrolled movement of chain and parts.c. Use of pressing equipment is suggested. Tools must be in good condition and properly used.d. Do not attempt to connect or disconnect chain unless you understand chain construction,

including the correct direction for pin/rivet removal or insertion.e. Do not attempt to rework damaged chains by replacing only the components obviously faulty.

The entire chain may be compromised, and it should be discarded.

4. Other cautions:a. Alterations and Repairs to chains should be made only by qualified personnel with parts and

components authorized by U.S. Tsubaki.b. Electroplating of Assembled Chains is not condoned. Plating of assembled chains could

result in failure from hydrogen embrittlement.c. Inspect Chains for shipment damage before installation. During operation, all chain systems

should be inspected on a regular schedule. Visually check for worn, damaged and broken partscaused by improper installation or maintenance, abnormal stress, temperature, humidity,abrasion or corrosion, possible interference with other system components and improperlubrication. (For correct lubrication procedures and systems, see the Engineering Section.)

d. Heating Chain with a cutting torch is not suggested unless absolutely necessary for removal. Ifcut in such a manner, it should not be reused.

e. Welding should not be performed on any chain or component.f. Average Ultimate Strength of a chain means the average load at which it will break when

subjected to a destructive tensile test. It does not mean working load. For complete information,contact U.S. Tsubaki Engineering.

g. Product Dimensions in this catalog are subject to changes and are intended for generalreference only. For exact current dimensions, request certified prints from U.S. Tsubaki.

Plastic Sleeve Chain

The main characteristic of this chain is that it has an engineering plastic sleeve between the pin and bushing.The engineering plastic roller is also available in combination with the engineering plastic sleeve.

1. The use of self-lubricating engineering plastic sleeves eliminates the need for lubrication.

2. Excellent wear resistance ensures long life.

3. Since no metal dust is generated from contact between the engineering plasticparts and the steel parts, your environment and equipment are kept clean.When using the stainless steel chain series, corrosion resistance is also increased.

4. The use of engineering plastic rollers results in significant weight reduction compared to all stainless steel chain (small “S” roller type: 15% less, oversize “R” roller type: 40% less).

5. With the use of engineering plastic sleeves and rollers, quiet operation is ensured (7 ~ 10 dB lower than stainless steel chain).

6. RS40, RS50 and RS60 with plastic sleeves are available upon request. Contact U.S. Tsubaki for details.

Standard Series : Engineering plastic roller and sleeve, other components steel.

Stainless Steel Series : Engineering plastic roller and sleeve, other components 304 stainless steel.

Notes:1. Conveyor LAMBDA should not be used in drive applications. It is designed for conveyor applications where the speeds are generally lower and the center distances

are longer than those found in drive applications. Conveyor series LAMBDA, except for RSC35-LAMBDA, has the same dimensions and the same working load as ourstandard attachment chain and the same link plate thickness as standard. RS35 standard connecting links cannot be used for RSC35-LAMBDA due to the differencein pin diameter.

2. Drive LAMBDA and Conveyor LAMBDA chains cannot be intercoupled.3. Connecting links for RSC80-LAMBDA ~ RSC100-LAMBDA and RSC80NP-LAMBDA ~ RSC100NP-LAMBDA have cottered pins.4. RSC35-LAMBDA lasts up to 5 times longer than standard roller chain without additional lubrication.

Crossrod ConveyorChain

Crossrod conveyor chain consists of two parallel strands ofstandard RS40 or RS50 chains, joined by crossrods on everylink. RS40 chain is used for light loads such as conveyingbread through coolers, wrappers and slicers. RS50 chain isfor heavier loads. When sanitary, noncorrosive qualities arerequired, crossrods can be stainless steel.

The connecting pins have milled flats and fit into a D-shapedhole in the link plate to prevent pin rotation and give longerlife. Chains are furnished in five-foot sections and run onstandard ASME/ANSI sprockets. Removable two-pitch linksections are available for repair.

U.S. Tsubaki ASME/ANSI single and double pitch roller chain is widelyused for conveyor service. The following procedure is useful for economicaland quick chain selection.

Step 1 : Confirm the operating conditions of the conveyorStep 2 : Tentatively select the chain sizeStep 3 : Calculate the design chain tension (actual chain tension)Step 4 : Verify the chain selectionStep 5 : Verify the allowable roller load

Step 1 Confirm the operating conditions of the conveyorThe following information is needed to design a chain conveyor.� Type of conveyor (slat conveyor, bucket elevator, etc.)� Method of chain travel (horizontal, inclined, or vertical

conveyor)� Type, weight, and size of materials to be conveyed� Weight of materials to be transported per foot of conveyor

length� Conveyor speed� Conveyor length� Lubrication Considerations for special environments

Step 2 Tentatively select chain sizeTo tentatively select the chain size, estimate the chain tension (T) bythe following formula. A chain with an allowable load equal to or over the above calculated chain tension may be tentatively selected.T (lbs.) = MT • f • k1

................ (1)MT : Total weight of material conveyed (lbs.)f : Coefficient of friction, sliding and/or rolling

(f1 and/or f2 of Table I and II)k1 : Chain speed coefficient (Table III)

Calculate chain tensionNext, the chain tension should be calculated using the actual weight of the conveyor chain and material conveyed,as shown below.

3. Calculate the required power

General Engineering Information

Points to consider:1) For long conveyors, use take-up devices to eliminate

chain slack. Take-up stroke = (center distance betweensprockets • 0.02) + catenary sag allowance.

2) Chain must always be engaged with at least 3 sprocket teeth.3) When two or more strands of conveyor chain operate, all

sprocket teeth on the head shaft should be aligned. The chainmay be matched at the factory for uniform length and attach-ment alignment for accurate multiple strand operation.

Considerations for Use in Special EnvironmentsANSI standard and double pitch conveyor chain can be operatednormally in ambient temperatures between 15°F and 140°Fwithout trouble.

When the chain is operated in very low or high temperatures,or in an abrasive or corrosive atmosphere, the following shouldbe taken into account.1. Under very low or high temperatures:

Chain must be selected in a different manner when it isoperated in freezing chambers, cold areas, when it passesthrough a heat-treatment furnace, or is affected by heatfrom the material conveyed.

2. In wet conditions:When chain is exposed to water, e.g., in a sterilizer or waterscreen, excessive wear due to insufficient lubrication andrust may shorten chain life. In these cases, a larger chainsize provides less bearing pressure and stainless steel orplated chain will provide rust prevention.

3. In corrosive conditions:When chain is exposed to an acidic or alkaline solution oroperated in a corrosive atmosphere, excessive wear mayoccur due to chemical corrosion on the chain parts in addi-tion to mechanical wear.

Hydrogen embrittlement may also occur in an acidicatmosphere. Roller chain is more easily affected by acidthan alkali. In special cases, electro-chemical corrosion mayoccur on the chain due to sea or mine water. Refer to the

table on page A-60 “Corrosion Resistance Guide”, for thecorrosion resistance of stainless steel.

4. In dusty conditions:When conveyor chain is operated in dusty conditions, i.e.,in the presence of coke, metal powder, and sand, the chainwears very quickly because foreign material gets between theparts of the chain and also the engaging surfaces of thesprocket teeth and chain.

In such cases, select a larger chain size to reduce the bearingpressure or choose a chain especially designed for high wearresistance.

The foregoing information is intended to provide general guidelines for conveyor chain selection. Please consult with U.S. Tsubaki for specific application problems.

Free Flow Conveyor – this is a conveyor system where the speed of conveyedobjects can be freely controlled and stopped at any time and at any positionfor accumulation or for performing a job at a station without stopping in theconveyor.

A typical application is, for example, an assembly or accumulation conveyorused in the electronics industry to transport consumer products such as TVs, VCRs, and radios, etc. Technical innovation in this field is very fast. To produce hi-tech products quickly, hi-tech assembly lines using quick andaccurate chains are necessary.

U.S. Tsubaki has developed the most advanced chains for Free Flow conveyorsdrawing on U.S. Tsubaki’s technological expertise and long experience as aleader in worldwide chain manufacturing. U.S. Tsubaki Free Flow chains havemany advantages.

■ DOUBLE PLUS® CHAIN

■ ROLLER TABLE

■ OUTBOARD ROLLER: SIDE AND TOP ROLLER CHAINS

Quiet operation is one advantage of using U.S. TsubakiDOUBLE PLUS® chain. Because materials transported onthe chain move 2.5 times faster than the chain itself,motor speeds can be reduced, cutting down on noise andcosts. Safety is ensured by the extra-large, engineeringplastic center rollers which allow for installation of a chaincover. The original design of U.S. Tsubaki’s aluminumguide rail is standardized for easy installation. Steel rollerDOUBLE PLUS is available for high load or high tem-perature applications.

The Outboard series consists of both side and top rollerchains. Outboard roller construction makes for a highlycompact conveyor system. Since a large number of rollerscan be installed, a conveyor can easily be made wheresmall objects are placed directly on the chain. Quickstart-up is also possible by ordering a chain with plasticbrakes.

Line pressure is notably reduced during accumulationbecause of the low roll-friction coefficient on the plasticrollers (between 0.06 and 0.10). This low roll-friction coefficient protects the conveyed object from damage. Inaddition, smooth transfer to the next line is ensured by theplastic rollers and special attachments with the same surface height.

Construction■ How U.S. Tsubaki DOUBLE PLUS chain

works

• When ConveyingFriction between the larger center roller and thesmall rollers allows them to rotate together inunison. The difference in diameter of the rollerscauses the speed of the conveyed object to beapproximately 2.5 times the speed of the chain.

• When AccumulatingThe large roller rotates freely in the oppositedirection of the small roller allowing conveyedobjects to accumulate. We call this free flowconveying.

■ Poly-Steel SeriesThis is a light-weight, low-noise chain. In addition, it is maintenance free since no lubrication is required. Outboard roller construction makes for ahighly compact conveyor. The ability to flex backwards adds to this by allowing easy layout on the return side to save space. All parts are made ofstainless steel except the outboard rollers and inner links.

■ Guide Attachment SeriesThe attachment is designed to prevent meandering. Plastic brake rollers can also be installed.

ENGINEERING INFORMATION

I. Selection Procedure for DOUBLE PLUS®, Outboard Roller and Top Roller Chain

1) Confirmation of operating conditions for free flow conveyorThe following information is needed in order to select anappropriate chain for free flow conveyor:� Material weight, dimension and quantity of the

conveyed object (including pallet)� Conveyor speed� Conveyor length (the length for accumulating and

transferring portion respectively)� Lubrication requirements and environment

2) Tentative selection of chain sizeT = WT • f • K

WT: Total weight of conveyed object except chain(lbs.)

f: Coefficient of friction f = f2+f3 (See page B-57,Tables 4 and 5 or Table 8)

K: Chain speed coefficient (See page B-57, Table 6)Note: In the case where two matched strands are to be

operated, the chain’s maximum allowable tension(shown in Table 7, page B-57) should be comparedwith T • 0.6 to decide the chain type and size.

3) Confirmation of the maximum allowable roller loadThe maximum allowable roller load for conveyed objectsshould not exceed the figures shown in Table 1. However, maximum allowable roller load for the base chain should be checked using Table 2.

Table 1 Maximum Allowable Roller Load for Conveyed Objects

This is the load at 2 strands for DOUBLE PLUS chain(lbs/.ft.)

II. DESIGN GUIDELINES FOR DOUBLE PLUS® CHAINi) Dimensions for both ends of the conveyor.

A typical arrangement of DOUBLE PLUS® components is illustrated in Fig. 1. The bracket is used to mount the plas-tic return guide to the aluminum guide rail, allowing thechain to flow smoothly between the sprocket and guiderail. See Table 9a for dimensions.

Figure 1–Typical arrangement of DOUBLE PLUS® components

ii) Screws, bolts, height of conveyor.The values for L shown in Table 9b and Fig. 2 vary because of the plastic bumper wall thickness tolerance.

Connecting the aluminum guide railConnect the aluminum guide rails by aligning the V grooveshown by arrow A in Fig. 2.

7) Selection Procedure Example for DOUBLE PLUS® Chaini) Confirm operating conditions for conveyor.Conveyor length: 30 ft.Dimensions of conveyed object: 1.5 ft. squareWeight of conveyed object: 53 lbs./piece

53 lbs./piece ÷ 1.5 ft. = 35.3 lbs./ft.Conveyed product speed: 30 ft./min.Chain speed: 12 ft./min.Full conveyor accumulatingQuantity of conveyed object: 20 piecesDry, in-plant use, normal operating temperatures (up to 77°F)

ii)Select initial chain size.Using the calculation method in Step 2 on page B-56:

TT = WT • (f2 + f3) • KTT = (35.3 lbs./ft. • 30 ft.) • (0.1 + 0.2) • 1.0 = 318 lbs.Ts = 318 lbs. • 0.6 = 190.8 lbs.Note: Presume two strands of chain, each loaded by 0.6

of the total.

Based on these calculations, C2040VRP-A chain is the pre-liminary choice, but this selection must be confirmed.

Note: C2040VRP-A weight/ft. = 0.67 lbs./ft. per strand (1.34lbs./ft. for two strands).

iii) Confirm the maximum allowable roller load.By consulting Table 1 on page B-56, you find that forC2040VRP-A, the maximum allowable roller load is 40 lbs./ft.for aluminum rail.

In this example, the weight of the conveyed object is 35.3lbs./ft. Therefore, C2040VRP-A can cover roller load.

iv) Confirm total chain tension.Using the calculation method of total chain tension (TT):

TT = (0 + 1.34) • 0 • 0.08 + 35.3 • 30 • 0.10 + (35.3 + 1.34) • 30 • 0.20 + 1.1 • 1.34 • (0 + 30) • 0.08

TT = 329 lbs.

TS = TT • 0.6 = 197 lbs. per strand

Now determine chain size.Multiply the chain tension (TS) by the chain speed coefficient(K) listed in Table 6 on page B-57, confirm with the followingformula:

TS • K ≤ Maximum allowable chain tension (Table 7).197 • 1.0 ≤ 200 (C2040VRP regular plastic)

In this example, we would choose C2040VRP-A Chain.

v)Calculate required power.*Presume gearmotor efficiency (η ) = 0.8

HP = 329 lbs. • 12 ft./min. • 1.1 = 0.17 = 1/4 HP motor

33,000 • 0.8

iii) Nominal spacing of conveyor supports.Proper operation of DOUBLE PLUS® Chain is maintainedby controlling the amount of deflection of the aluminumguide rail. This deflection is determined from the weight ofthe conveyed goods and the second moment of area,shown in Table 9c. To control deflection, supports should bespaced as shown in Fig. 3, in accordance with the followingequation:

Determining support spacing

l (in.) = [ 384 • E • I • d • 12 ]1⁄4

5 • 0.6 • W

l = spacing support (inches)E = Young’s Modulus = 9.956 x 106 lbs./in. I = Second moment of area = in.4 (See Table 9c.)

d = Deflection = 0.079 in. W = Total conveyed weight = lbs./ft.

Note: The total conveyed weight (W) is not always distrib-uted evenly between the two conveyor strands. This is takeninto account with the factor 0.6.

iv) Finishing the ends of the conveying side.

Put a chamfer on the ends of the upper rail that thechain’s small rollers travel on (Fig. 4).

Figure 4–Location of Chamfer

It is possible to prevent the chain’s large roller from dippingat the chamfered portion by installing a support for thelarge roller on the ends of the rail on the driven side.

v) Aluminum frame with steel rail.

(1) Two basic constructions are used when buildingguide rail with aluminum frame and steel rail:

For C2030VRP-R3LS, a steel rail (no. 3) is arranged in thevertical position and lock screws (no. 4) are secured intothe frame (no. 1) from both sides (see Fig. 5a). See Table9d on page B-60 for dimensions and hardware.

(3) Important points when handling steel guide rail• When cutting the guide rail with steel rail

1) Cut anywhere other than the central portion orscrewed portions of the rail.

2) Insert lock screws into the steel rail and inner railalong with the inner rail and main rail at 0.6 ~ 1.2 in.from the cut end.

3) Machine all parts individually.4) Completely remove all burrs before reassembly.

Note: Use screws according to Table 9d on page B-60when reassembling the conveyor.

• When connecting the railAfter connecting the rail, put small chamfers on the matingfaces of the steel rail in both directions where steps occur.These prevent the chain rollers from getting caught.

vi) Transferring objects between conveyors.To convey pallets in a stable condition at the transfer portionof the conveyor, install a roller between the two conveyors orthe shafts of the sprockets (see Fig. 7). Be sure that the dis-tance l from the ends of the rail to the roller that supportsthe pallets is less than 1/2.5 times the pallet length in theconveying direction.

Figure 7–Install a roller as shown for a straight line transfer

vii) Take-up.The amount of take-up l = (L • 0.02) + marginal length(0.02 = Allowable chain wear elongation 2%)

Allow for some sagging (up to 10% of the span) in the chainon the bottom of the driver sprocket. Adjust the take-up so thatthe slack does not exceed the values in Table 9f. (see Fig. 8.)The total arc of contact between the chain and sprocket shouldbe more than 130°. If take-up cannot be set up as shown inFig. 9 due to space limitations, refer to Fig. 10.

viii) Maximum conveyor length.DOUBLE PLUS® Chain operates well on conveyors withlengths not exceeding 50 ft. When conveyor distances aregreater than 50 ft., make several shorter conveyors in line.If you require one continuous system longer than 50 ft., consult U.S. Tsubaki.

ix) For DOUBLE PLUS® Chain with Snap Covers. When using the arrangement as shown in Fig. 11, beaware that the sprocket cannot engage the chain from thetop surface of the snap covers. When bending the chaintoward the snap cover side, do not bend beyond the Rdimension of the plastic return guide (see page B-46).Snap covers and installation are shown in Figs. 12 and 13.

RS Plastic ChainStandard SeriesRS Plastic chain consists of polyacetal chain links and 304 stainless steel pins andoperates with standard roller chain sprockets. Based on power transmission roller chain,U.S. Tsubaki RS-type has a flat top side for power transmission or conveying use.

“E” Series (Electro-Conductive Series)The special plastic used in the “E” series is electro conductive and permits electricalcharge. These chains are suitable for applications where there is electric noise, electricsparks, or where dust collects due to static electricity. Volume resistivity: 106•cm

“Y” & “SY” Series (Anti-Chemical Series)The amazing “Y” & “SY” series utilizes an engineering plastic which permits the chain toperform well even where chloride, acid, alkaline, oxidizers and most organic solvents arepresent. “SY” series is a combination of “Y” series plastic block links and titanium pinsand performs well even when exposed to sulfuric and hydrochloric acid.

“K” Series (Heat Resistant Series)The U.S. Tsubaki “K” series is made of a resilient new engineering plastic which canwithstand environments where temperatures reach 284°F. In contrast to plastic chainsmade of conventional plastic, this chain will not lose its valuable properties at hightemperatures.

Note:1. The Engineered Plastic Chain Catalog is also available upon request.

For details consult U.S. Tsubaki.2. “K” series chain is clip-type construction and has a slightly longer pin.

Step 5 Select top plate widthGenerally, the top plate must be wider than the material conveyed.When materials are very wide and none of the top plate widthsare satisfactory, top plates of the same width may be used inmulti-strand arrangement. Top plates of different widths can beused together, but this is not desirable since the tension on thechains will be uneven.

Step 6 Calculate chain tension (T)1) Linear movement

(TS, TT, TP, TN, TTP and RS-P chains)T = (M + 2.1 w) Lf2 + ML’f3 . . . . . . . . . . . .Formula 1

2) Curved movement(TRU, TKU, TPU, TNU and TTU chains)The chain tension for curved movement is calculated similarly tothat for linear movement. The tension at corners, however, is com-pensated for by angle factor (K2) and length factor (K3).Calculations are shown below for the illustrated examples.

The tension on the chain at each part ABC . . . F must be calculated.The tension at F is the greatest acting on the chain.

T = T� ....................Formula 2Slack side:

Chain tension at � : T�

T� = L1wf2k2 , L1 = l1 + R1k3 (k2 and k3 at 180°)Chain tension at � : T�

T� = {T� + L2wf2} k2, L2 = l2 + R2k3 (k2 and k3 at 90°)Chain tension at � : T�

T� = T� + L3wf2 , L3 + l3

Determine chain sizeMultiply the maximum chain tension (T) bythe speed coefficient (k1) taken from TableVII and verify that the following equation issatisfied.

T X k1 � Chain maximum allowable load.................. Formula 5

When the maximum allowable load isinsufficient, it can be corrected by usingtop plates with narrower width andincreasing the number of chain strands, orby splitting into many short conveyors.

Conveyor designThe layout of a conveyor varies with thetype of chain used. A typical layout isshown below. Goods should be conveyedon the tension side of the chain, and theslack (return) side should be supported byguide rails with sloped ends to preventchain vibration and conveyor pulsation.

2-1 Guide railThe guide rail consists of the conveyor frameand liner. The liner sides with the top chain tominimize frictional resistance and wear sothe chains are protected and driving powercan be minimized.

2-2 Location of guide rails and sprocketWhen the chain engages with the sprocket,the chain itself moves up and down slightlydue to the polygonal effect of the sprocket.Therefore, the guide rail on the loaded sidemust be positioned so that the chain is horizontal when at the highest level. Guiderail installation dimension (A) is determinedfrom the following equation.

2-3 Slack side guide rail arrangement

Top plate sliding (applicable for all top chains)

(1) Slack of 3.5 ~ 5.5 inches (during operation) is needed under the drive sprocket.

(2) Engagement angle must be more than 150° between the drive sprocket and the chain.

(3) The radius R (inches) of the guide rail must be larger thanthe radius of chain back-bend given in the table below.

Radius of Chain Back-bend(in.) (in.)

(4) Guide rails must have sloped ends to prevent interference with the chain.

2-4 Connection of additional conveyorsIf a conveyor is too long, the chain tension will increase and chain strength will not be sufficient. In such cases, additional conveyors should be used.

Locations of the chain and the guide rail are very importantfor a smooth transition between conveyors. Two parallelchains must be positioned at the same height, or the outputchain must be positioned slightly higher than the receivingchain. The guide rail must be shaped such that transition ofgoods can be accomplished smoothly.

ATC Chain

ATC (Automatic Tool Changers) chain is widely employed in MachiningCenters because of its economy, efficiency and functional versatility.

Advantages of ATC Chain1. A high degree of layout freedomThe high degree of layout freedom possible with chain type ATC allows for efficient use of space.

2. Space savingChain type ATC can handle up to 50% more tools than disc types in the same space.

3. Economical and efficientAs more tools can be contained in the chain type than in thedisc type, chain type ATC can be made lighter and hashigher performance.

4. Easy standardization of designSimply by lengthening the chain, the number of tools can beincreased, but unlike the disc type, this does not change thetool replacing position. This versatility lets you standardize onchain.

HP-T typeThe HP-T series is the hollow pin type chain complete withtool holder. Since the chain can bend backward, freedom oflayout is exceptional, and a large number of tools can be heldin a small space. Tools are held on the pitch line of the chainproviding extra stability.

Hollow pin type chain is also available upon request, and canbe supplied with plastic pots.

SK typeThe stay pin series (SK02, SK04) resists lateral loads on thechain, and the side roller series (SK03, SK04) prevents toolsfrom tilting and facilitates their positioning.The chain can be supplied fitted with plastic pots.

HP-T TypeHP-T type ATC chain is based on the HP type with steel toolholder. The inner diameter of the pin is tapered and aretaining function is installed on the pin.Economical: Additional installation of the tool holder is

not necessary.Accurate holding: As the tool holder is combined with the

chain, backlash is reduced.Compactness: Pin outer diameter and link plate width are

smaller than those of HP type.

1) U.S. Tsubaki standardized ATC chain is designed withpull stud, key, number plate and plastic sleeve.An engineering plastic sleeve is fitted to prevent contactwith the metal taper parts and protect the shank frombeing scratched.

2) Attachment chains other than the listed ATC chainline-up are also available to satisfy your specialrequirements.

Safety device for HP-T type chain (optional)

In the case of horizontal drive HP-T type chain (with tools vertically suspended), we can provide the tool holder with an optional safety device.

The safety device prevents the tool from falling out of the tool holder during operation.

Note:The safety device is not available for Shank No. 40. Instead, we suggest using a higher tool extraction force.

Pushing the safety device pin by the cylinder easily releases the tool from the retention knob by spring force.

USING ATC CHAIN

1. Guide Applications■ SK and SK-W type Chains

2. Positions for Picking Up Tools

The best position to pick up a tool is at the drive sprocket,especially in the case of SK type ATC chain.

3. Picking Up Tools with theClamping Method

Clamping equipment is necessary for HP-T and HP type ATCchain.

4. Initial Chain Tension

Please apply initial tension up to 1/2 of the working load of theATC chain and adjust the chain tension to avoid chainvibration.

5. Chain Tension and Driving Power

6. Tool Weight and Chain Type

7. Tool Gripping Method

8. ATC Chain Lubrication2) Tool layout and driving power:

Layout should be designed for optimal tool balance toreduce the driving power required and the chain tension.

Please check:1) Thrust load when picking up or setting tools into the pot.2) Eccentric load due to overhang of the tools.

Because precision is essential, lubrication is very importantfor ATC chain. Proper lubrication forms an oil film whichreduces chain wear, chain friction, and noise. The chainlubrication should be maintained as follows:

1) Lubrication Points

Lubrication should be applied and maintained between thechain link plates and the bearing area. Apply the lubricantmanually or automatically using a drip lubrication system.

2) Lubricant Selection

General purpose oil is acceptable for lubrication, but thehigher the quality the better. If the viscosity of the lubricant istoo low, it will leak away and have to be replaced often and ifthe viscosity is too high, it will not reach the critical parts, andthe lubrication will not be effective.

The following lubricants are suggested:Lubrication oil: Mobil® SAE #30 ~ 40 machine oil or equivalent.

Frequency and amount of lubrication:

Ensure that the bearing portion is always moist withlubricant. The amount of lubricant should be enough toensure that lubricant reaches all critical points. If the toolsare heavily used or the number of bending cycles of thechain is very high, increase the frequency of lubrication.

Driving MechanismCableveyor is installed as shown in the picture below.Within the moving distance, it is able to move freely. Theelement to be moved is attached to one end of theCableveyor (A) and the other end to where the cables orhoses are inserted (D).

A horizontal axis is always maintained between (A) and(B). The bending radius of the Cableveyor remains con-stant even when in motion. The diagram below showsthis as the Cableveyor moves from A to A’ while bend-ing evenly (R).

MOVING DISTANCE AND THE SUPPORT ROLLER

The straight distance normally traveled by the Cableveyor isreferred to as the “freespan”. The length of the freespan isdetermined by the weight of the cables or hoses. If half thedistance the machine needs to move is over the freespancapacity, supporting equipment such as a support rollermay be used to increase the length of travel. The supportroller enables the freespan distance to be extended beyondthe original distance.

INSTALLATION

S: Moving strokeK: Margin lengthF: Freespan

Without support roller

With one support roller, the allowable freespan can be increased up to three times the moving distance.

With two support rollers, the allowable freespan can beincreased up to four times the moving distance.

Note: Use of three support rollers or more is not economical. Forsupport roller dimensions please see pages B-98 and B-99.

A constant bending radius with straight, horizontal movement provides efficiency and smooth operation.

TK CableveyorCONSTRUCTION AND FEATURES

TK Cableveyor is constructed of steel chain with aluminum supporters to give high strength and durability for diverse applications.The holes of the supporters are made to fit the cables or hoses precisely. These cableveyors are very versatile and can fit mostindustrial machines.

TK Type

TK TYPE OVAL CABLEVEYOR

• TK type Cableveyor has been designed to protect workersfrom accidents by utilizing specially shaped link plates. Thislink plate design has solved the problems that may occurdue to crevices between link plates.

• All link plates are offset type. The pins at the movingconnection are through hardened by an inductionheat-treatment to provide high abrasion and deformationresistance. TK type Cableveyor is also effective against sideforce damage.

• Proper size holes will be made to your specifications. Theholes on the stays are made to fit the diameter of thecables or hoses.

• By using the correct size holes in the stays, cables andhoses will be very steady and well protected.

SUPPORTERSThere are two types of supporters for TK type Cableveyor, aone-piece supporter and a split supporter. The split supporteris very convenient for long moving strokes, if an odd-shapedattachment is used on the cables or hoses, or if a large number of cables or hoses must be installed.

SelectionSTEP 1. SpecificationsWhen selecting the correct Cableveyor, several things must betaken into consideration. The following data must be known forproper selection.1. Application conditions.2. Moving stroke (ft.)3. Moving speed (ft./min.)4. Number and external diameters of the cables/hoses to be

installed.5. Total weight of the cables/hoses. (lbs./ft.)

(In the case of hoses, the weight of the carrying element such as oil, water, etc., should be included.)

6. Allowable bending radius of cables and hoses (inch).This is determined from the intended function.

STEP 2. Determining the moving stroke and bendingradius

The tentative selection of Cableveyor and the support roller ismade as follows. Determine the approximate radius with thecapability graph (page B-102). This graph is based on thedistance of the moving stroke and the weight of the cables andhoses.1. Estimate the distance of the moving stroke when a support

roller is not being used. If the moving stroke is too long, usea support roller. Note that in some cases, it is more efficientnot to install one.

2. Determine the bending radius of the cables or hoses.

Allowable bending radius (Actual bending radius) < Standard chainbending radius (R).

Regarding the bending radius of the cables or hoses, refer to the calculations below.In the case of cables,Allowable bending radius � external diameter • 6In the case of hoses,Allowable bending radius � external diameter • 9

STEP 3. Adjusting the moving strokeThe length of moving stroke must be adjusted if used under thecircumstances listed in the Service Factor Table below.

Length of moving stroke • service factor = adjusted moving stroke

For selection purposes, use the adjusted moving stroke lengthwith the capability graph.

The values of F0, F1, and F2 must not exceed the maximumfreespan from the capability graph below. If it does, a largerchain size must be chosen or more support rollers added, butonly up to a maximum of two.

How to use the capability graph

For the TK095, if the weight of the cables or hoses is 4.03lbs./ft., the moving strokes are:

25.6 ft. with no support roller38.4 ft. with one support roller51.2 ft. with two support rollers

There are five different bending radii of the chain standardizedat 4.92, 5.71, 7.87, 9.84, 11.81 inches. Maximum hole diameteris 1.81 inches.

Example

Weight of the cables or hoses: 2.69 lbs./ft.Allowable bending radius of cables or hoses: 7.48 inchesExternal diameter of the biggest cable or hose: 11.81 inchesMoving stroke: 26.25 ft.

With no support roller:The intersection of the cable weight axis (2.75 lbs./ft.) and thefreespan length axis (26.25 ft.) at point A is within the range ofTK095. Therefore, it can use a bending radius within 78.74inches and satisfy the diameter of the cable or hose.

With one support roller:The intersection at point B is within the range of TK070, butthe allowable bending radius of cables or hoses is more thanthe allowable bending radius of the cableveyor. The diameter ofthe hoses or cables is bigger than that which is on the chart.Therefore, it does not satisfy the requirement.

STEP 1. Specifications

See STEP 1 of the SELECTION outline (page B-101).

STEP 2. Tentative selection

From the capability graph on page B-102, TK130 would satisfywhat is required since it has no supporting roller, and since themoving stroke is 29.5 ft. (length of travel) and 6.7 lbs./ft. for cableand hose weight.

STEP 3. Selection of the bending radius

R11.81 and R15.35 will satisfy the requirement for a larger thanallowable bending radius (10.63 inches).

STEP 4. Calculation of the number of chain links

Once the chain size has tentatively been referred to, the number of chain links may be calculated according to the following equation.

S 354– + �R +15.35 ––––––– + 11.81� + 15.352 2

l = ––––––––––– = ––––––––––––––––––––– = 44.9 links 5.12 5.12

The fraction is rounded off to l = 45 Links.

STEP 5. Freespan confirmation

Freespan F (without support rollers) is confirmed by adding themargin length (K’) + (S/2).

354130 • 45 links – (––––– + 300 �)

2K’ = ––––––––––––––––––––––––––– = 8.03 inches

2

S 354F0 = – + K’ + ––––– + 8.03 = 85.20 inches

2 2

From the capability graph on page B-102 a freespan of up to17.22 ft. is approved for a cable/hose weight of 6.72 lbs./ft.Since F0 = 15.43 ft. is less than 17.22 ft., the TK130, R11.81chain size is the most suitable. If F0 > 17.22 ft., a larger chainsize should be used — TK180, R11.81, for example.

STEP 6. Standard supporter selectionSupporter hole diameter may be calculated by the followingequation, where D � 1.1d and where D is rounded off to thenearest even whole number, making the diameter 1.89 • 2,1.58 • 2.

The supporter length B’ is –B’ = �D + �C + Min.36 (C = Min.1.42)B’ = {(1.89 • 2) + (1.58 • 2)} + (0.16 • 3) + 1.42 = 8.82 inches

The supporter dimension table shows that a supporter of thissize fits cables/hoses of 1.73 inches the best. When deciding onthe supporter dimensions, the next largest size appearing onthe table must be chosen when the calculated figure does notappear. For example, a value of 8.82 would take the next biggerfigure on the table, or 0.98. As the supporter length B’ becomesgreater, the spaces between holes (C) must also increase tomaintain balance.

(1) A chain guide is necessary for Cableveyor. An angled steelplate is best.

(2) Installation height of the moving bracket (H’) and tolerance forthe center of the fixed and moving brackets (E) should be setaccording to the table below.

Dimension in inches

(3) Under normal circumstances, lubrication is not necessary.However, for corrosive conditions, a lubricant should be usedfor protection.

(4) Since the TK types do not bend at the bracket chain joint, aminimum extension margin of 1.5 pitches (K on the diagramabove) should be adhered to. If this extension margin isdifficult to comply with, only one pin should be used in thecenter of the moving bracket. In addition, if the unit isoperated at speeds of 65 ft./min. or more, the location of themoving bracket and fixed bracket should be switched. Twopins should be used with the moving bracket and only one pin(in the center) with the fixed bracket.

(5) If the TK split-type supporter must be detached, care shouldbe taken to reassemble the supporter in the same way withthe corresponding marks on each half of the supporterproperly aligned with each other.

(6) When detaching and reassembling supporters, make surethat the chain is kept horizontal. If not, the chain will not movein a straight line.

(7) Check that bolts and other hardware are tight when assem-bling and when operating, since they may become loosethrough operational vibration.

(8) Do not put heavy objects or allow people to sit on the chain,as this will result in chain damage.

(9) Note that the chain will sag in its unloaded condition as it isdesigned to straighten out by its own weight when attached.

Notes on Fitting Cables or Hoses into the Cableveyor

(1) The end of the cable/hose should have an extension marginto insure that no damage occurs between the cable/hose andits attachment. Usually, this amounts to six times the hosediameter.

(2) The minimum cable/hose length necessary is given by thefollowing equation:

L = {(chain pitch • link number) + cable/hose length fromchain to its attachment} • 1.015

Note, however, that the hose’s internal pressure causes aslight reduction in hose length. This should be consideredwhen attaching hoses.

—* These items have no hub step.

TAPER-LOCK type W weld-on hubs aredesigned for use in applications such aswelding to plate sprockets, pulleys, and agitators. They are made of steel, drilled,tapped, and taper bored for TAPER-LOCKbushings.

U.S. Tsubaki offers the most complete line of QD® and TAPER-LOCK weld-on hubs forinsertion and welding to produce “B” stylesprockets, sheaves, and other applicationswithout hub protrusion. To provide greaterstrength for this type of shaft-locking mechanism and to reduce heat distortioncaused by welding, these hubs are dimensionally

the same as our sprocket items. Special dimensional hubs are available per yourspecifications on a made-to-order basis. All U.S. Tsubaki hubs are made from steelbar stock (not powdered or sintered metal).The QD and TAPER-LOCK weld-on hubs listed below include appropriate taperedbores and mounting holes.

C-70

Dimensions are in inchesunless otherwise indicated.

You need Adjustable Idler Sprockets to:• Obtain proper chain tension when neither driving nor driven

shaft is adjustable, and to take up slack chain developedthrough normal chain wear

• Guide chain around an obstruction • Prevent whipping action in the slack span of chain transmitting

an uneven load • Bring about greater chain wrap around a small sprocket,

particularly if it is the lower sprocket in a vertical drive • Provide for reversed direction of rotation of a sprocket in

contact with the outside of the chain

Idler sprockets should not rotate at greater speeds than areallowable for drive sprockets of the same size. They should bemounted in contact with the slack span of chain. Mount them onthe outside of the chain when the arc of chain wrap on thesmaller sprocket would otherwise be less than 120°.

It is advisable that idler sprockets have at least three teeth inmesh with the chain. Inside mounted idlers usually account forquieter operation, especially if centers are short and speed ismoderately high.

All U.S. Tsubaki sprockets are made from highquality steel. Since chain loadings are evenlydistributed over all engaged sprocket teeth,tooth breakage or distortion is not normally aproblem. It is seldom necessary to use specialhigh strength material.

Sprocket diameter and pitch determine the specific material used.

The hardening process of small diameter, smallpitch sprockets is usually a one-step procedure:heat treatment (electrical induction). Largediameter, large pitch sprockets can usually bedirectly flame hardened. These methods areused to provide a high hardness at the wearareas, plus provide the ability of the tooth toabsorb shock loads. This is accomplished byhardening only the wear area of each toothwhile maintaining a ductile tooth core which istough and resilient. The hubs and bores remainsoft to permit reworking.

The general guidelines for sprockets are:

The above maximum bores are not approved for severeservice conditions or for Cast Iron Sprockets.

For severe service conditions maximum bores should not begreater than 2⁄3 of the diameter of the hub.

Maximum bores for Cast Iron Sprockets should be about 15%less than for steel with 1⁄4” as the minimum difference.

Standard Keyways and Set Screw

NOTE: As a general rule, the hub wall over the keyway should be equal to or greater than the diameter of the set screw.*Set screw size may vary depending on the hub wall thickness.

Shock Relay for Overload Protection

U.S. Tsubaki SHOCK RELAY monitors the change in motor current that closely approximates thetorque output of the motor. Should the motor current exceed the preset LOAD CURRENT point for apreset length of SHOCK TIME (continuous overload time), the SHOCK RELAY will shut down themotor power supply.

DIAGRAM OF OPERATION TYPICAL CONNECTING DIAGRAM

TSB151, TSB152

M MotorMC Electromagnetic ContactorTH Thermal Overload RelayCB Circuit Breaker

Note: Refer to Specifications on page D-15.

ACTUAL LOAD METER

Actual current of the motor is indicated in percentages, which makes it easy to set “LOADCURRENT,” regardless of the value of the actual current load.

LOAD CURRENT

This presets the load current at the optimum setting in the range from 30% to 130% of themotor’s current. When the actual load currentexceeds the preset current for the presetSHOCK TIME, the SHOCK RELAY trips to breakthe motor circuit. Audible alarm devices or warning lamps may be installed if desired.

The LOAD CURRENT should be preset byobserving the ACTUAL LOAD METER conditionbecause the motor generally runs under its ratedcurrent value.

FINE ADJUSTMENT

Adjustment is preset at the factory. When fineadjustment of actual load current is required,this may be used to adjust from –5% to +30% ofthe indicated meter value.

START TIME

When starting a motor, the starting current valueis greater than the running current. This startingcurrent value continues until the motor reachesnormal speed. During this starting period, thetime of which mainly depends on the type ofload, the function of detecting the overload current is disabled. Adjustable range is from 0.2to 20 seconds.

TERMINALS FOR CONNECTION

All terminals are located on the upper surface toprovide easy access.

POWER INDICATOR

Indicates that the power supply is on.

TRIP INDICATOR

Lamp comes on when SHOCK RELAY trips.

TEST BUTTON

This switch is used to verify SHOCK RELAYoperation.

RESET BUTTON (manual)

Reset can be done quickly whenever a cyclerestart is desired.

SHOCK TIME

This presets the overload period. Range is vari-able from 0.2 to 3 seconds. Every momentaryload over the preset current with a shorter peri-od than the preset period is ignored. When theoverload equals the preset period, the SHOCKRELAY will trip immediately to break the powersupply to the motor.

The TSB151 and TSB152 series SHOCK RELAY allows easy connection into new or existing applications. For single or threephase motors, simply wire the current transformer that we supply into one line of the motor and the SHOCK RELAY into thecontrol circuit (stop-start circuit).

The SHOCK RELAY is powered by the same voltage as the control circuit to the motor starter, usually 115V or 230V singlephase. If a different control voltage is used, a step down transformer may be required.

The supplied current transformer is then connected in one line of the motor that is being monitored. Motor voltages above 600volts require special considerations. Contact U.S. Tsubaki.

For use with TSB152, TSB152A, TSB152M, TSB152WWhen ordering the TSB152, please select the correct size current transformer from the chart below. The transformer selected should closely match the motoramperage. U.S. Tsubaki will include the transformer youselect with the TSB152 Shock Relay.

When selecting a Shock Relay and compatible CurrentTransformer, locate the closest rating to the actual motorcurrent in the list.

Selection Example1. For 4 pole, 230V, 71⁄2HP motor: rated current 21.5

amps, choose TSB152, 100AT current transformer.2. For 4 pole 230V, 50HP motor: rated current 124

amps, choose TSB152, 250AT current transformer.

This presets the overload period. Range isvariable from 0.2 to 3 seconds. Everymomentary load over the preset current with ashorter period than the preset is ignored. Whenthe overload equals the preset period, theSHOCK RELAY will trip immediately to breakthe power supply to the motor.

START TIME

When starting a motor, the starting current valueis greater than the running current. This startingcurrent value continues until the motor reachesnormal speed. During this starting period, thetime of which mainly depends on the type ofload, the function of detecting the overload isdisabled. Adjustable range is from 0.2 to 20seconds.

Overload Protection for D.C. Motors

ACTUAL LOAD METERActual current of the motor is indicated inpercentages, which makes it easy to set “LOADCURRENT,” regardless of the value of the actualcurrent load.

LOAD CURRENTThis presets the load current at the optimum settingin the range from 30% to 130% of the motor’scurrent. When the actual load current exceeds thepreset current for the preset SHOCK TIME, theSHOCK RELAY trips to break the motor circuit.

START TIME

When starting a motor, the starting current value isgreater than the running current. This starting cur-rent value continues until the motor reaches normalspeed. During this starting period, the time of whichmainly depends on the type of load, the function ofdetecting the overload current is disabled.Adjustable range is from 0.2 to 20 seconds.

CURRENT FLOW INDICATOR

This lamp lights when the load current flows intothe SHOCK RELAY. This is after the fixed 3-secondstart time.

SHUNT SELECTION

The D.C. Motor Shock Relay has basically thesame functions and dimensions as the standardTSB152 and TSB50. Differences exist in that ashunt is required to monitor direct current of theD.C. motor in place of using a current transformer.

Whole New Approach to Replacing Keyways

Connecting Principle

Taper rings (A) and (B) fit perfectly with the tapered inner andouter rings. By tightening the locking bolts, taper rings (A) and(B) generate clamping pressure (P’ and P) against the outerand inner rings to produce the frictional force to join the shaftand hub. A slit is provided on the circumference of the outerand inner rings to secure the clamping force.

T max: Maximum torque (ft./lbs.)P max: Maximum thrust load (lbs.)

d: Shaft O.D. (ft.)2. Hub diameter calculation

a) Standard hub diameter (flange coupling, V sheave, etc.):Min. hub outside diameters (DN) are shown on pages D-22, D-23, D-26 and D-27 based on the yield point of hub material and the length of the hub. Hub diameter must be equal to or larger than (DN). Special hub diametercan be calculated by the following:

b) Hubs of special material:Calculate hub diameter using the following formula (notapplicable to non-ferrous metals).

3. Hub widthThe AS Series POWER-LOCK is not self-aligning.Thus centering (B – b) must be performed.Suggested “guide length” (B – b) is to be equal to or greaterthan one half of the shaft diameter.B – b � d/2 (d: shaft diameter)Hub width (B) can be calculated as follows:B � b + d/2 - - - (5)Note: POWER-LOCK cannot be centered under the condition of B = �.

4. Machining tolerance and surface roughness

Machining tolerance for counter bore diameter of hub “D”and shaft diameter “d” are listed on pages D-21, D-24 and D-25. Required surface roughness of 125 RMS. Determinethe tolerance of the guide according to the centeringaccuracy required.

Mounting and RemovalMounting

1) Clean and lightly oil or grease the shaft and hub bore. (Donot use oil or grease containing molybdenum disulphide.)

2) Remove the locking bolts from the POWER-LOCK® andclean and lightly oil, or grease the contact surfaces.Threads and seats of the locking bolts must also besufficiently lubricated.

3) Slip the POWER-LOCK and hub onto the shaft, tighten thelocking bolts by hand until a slight positive contact is felt, andset them at the predetermined position, just as you wouldtighten lug bolts on a car wheel. When it is difficult to slip on,loosen the bolts. (Do not strike with a hammer.)

4) Next, determine the relative positioning between the hub andshaft (on the circumference and shaft line), and tighten thefour bolts positioned diagonally with 1/4 of the requiredtightening torque. Proceed to tighten the remaining bolts inthe same manner.

5) Increase the tightening torque to half of MA and tighten thebolts in the same way as in Step 4.

6) Increase tightening torque to MA and tighten the bolts.7) Check the tightening torque of the locking bolts in sequence.

This completes the mounting procedure.

Removal

1) Make sure that no torque or thrust is being applied to theshaft and hub. When shaft and hub are heavy, take them offthe shaft carefully.

2) After completing Step 1, loosen the locking bolts. (No definitesequence is required.)

3) If the POWER-LOCK is still locked even after loosening thebolts, insert bolts into the jack screw holes (see photo below)and screw them in until it unlocks.

Use a Torque Wrenchto Tighten Locking Bolts

The POWER-LOCK ensures transmissible torque (Mt) andthrust (Pax) only when the locking bolts are tightened to theproper torque. For this reason, use a torque wrench to tightenthe locking bolts and thus obtain maximum performance fromthe POWER-LOCK.

General Information1) Shafts with existing keyways:

Transmissible torque and thrust capacities of the POWER-LOCK® must be decreased by 10% when used with a shaftwith a keyway such as a motor shaft.Transmissible torque: Mt • 0.9Transmissible thrust: Pax • 0.9

2) Surface pressure (P) and (P’):Contact pressure values of shaft (P) and hub bore (P’)listed on pages D-21, D-24 and D-25 indicate mean valuesonly. These rated surface pressures will fluctuate from–20% to +40% due to the variable friction componentforces resulting from the locking bolts. Transmissible torque(Mt) and thrust (Pax) are calculated as minimum values,provided that POWER-LOCK is to be used under the listedsurface pressures, (P) and (P’). Transmissible torque (Mt)and thrust (Pax) may increase by approximately 70% abovethe listed ratings in actual applications.

3) Radial load applications:Should POWER-LOCK be subjected to heavy radial loads(Pr) in such applications as wheel drives, calculate surfacepressure (Prad) on the shaft and (P’rad) on the hub asfollows:POWER-LOCK may be used if the surface pressure on theshaft (Prad) and the surface pressure on the hub (P’rad)are equal to or less than one half of (P) and (P’).

1.3 • Pr 1Prad = –––––– � – Pd • � 2

Pr: Radial load (N) (lbs.)�: POWER-LOCK inside width (in.)d: Shaft dia. (in.)D: Hub bore inside dia. (in.)P: Surface pressure on shaft (psi)P’: Surface pressure on hub (psi)When radial load is applied to POWER-LOCK, the abovevalues of (Prad) and (P’rad) should be added to (P) and(P’) respectively in order to calculate the hub outside dia.(DN) or hollow shaft inside dia. (dB).

1.3 • Pr 1P’rad = –––––– � – P’D • � 2

4) Bending moments:POWER-LOCK is not designed to transmit bendingmoments. However, POWER-LOCK will tolerate limitedbending moments as shown in table listed below.M � Mo. • n2

M: Bending moment working on POWER-LOCK (in./lbs.)Mo: Allowable bending moment (in./lbs.)n: Number of POWER-LOCK (N � 4)Should bending moment values be close to the allowablebending moments values listed in the table, use (PtM)instead of hub surface pressure (P) when calculating huboutside dia. (DN).

5) Allowable value of tightening torque (MA):Transmissible torque (Mt) and thrust (Pax) values are basedon the correct tightening torque of the locking bolts.Acceptable range of the tightening torque is �5% of thelisted value. Use an accurate torque wrench to tighten it.

6) Loosening of locking bolts:Manufactured of special high-tensile steel, the locking boltswill not loosen due to vibration.

7) Influence of temperature:The use of POWER-LOCK at temperatures above 400°F(200°C) is not suggested, since the tensile strength of thelocking bolts may decrease substantially.

8) Outdoor use:When a standard POWER-LOCK is to be used outdoors, itshould be lubricated with grease and a cover should beinstalled to protect against corrosion. If this is not practical,stainless steel POWER-LOCK (see page D-24) and specialcoating POWER-LOCK are available.

EL Metric SeriesPOWER-LOCK® EL is a frictional keyless shaft-hub locking device for connecting hubs andshafts subject to large torque variations. The EL series POWER-LOCK is a simple structure con-sisting of two tapered rings.

1. COMPACTPOWER-LOCK EL is very compact and lightweight,and does not require a wide fitting space.

2. DESIGN VERSATILITYProven performance and reliability in hundreds ofapplications worldwide.

3. EASY ANGULAR AND AXIAL POSITIONINGExtremely easy to position, and can be used at anyplace on the shaft.

4. COMPLETELY TIGHT FIT WITH NO BACKLASHPOWER-LOCK EL provides a completely tight fit, sothere is no backlash and no seizure.

5. BALANCESBeing a complete ring with no slit, POWER-LOCK ELprovides a well-balanced fitting.

6. EASY ASSEMBLY AND DISASSEMBLYPOWER-LOCK EL has no moving parts, and wear isnegligible. Frequent disassembly and reassembly ispossible.

■ CONNECTING PRINCIPLE

When locking force F is applied to POWER-LOCK EL, itpushes the inner ring and outer ring together, generating radial direction pressures (P, P’) on the shaft and to thehub bore.

These pressures (P, P’) create the frictional connection.When the locking bolt is untightened, POWER-LOCK EL can be easily disassembled and removed.

INFINITELY VARIABLE SPEED DRIVESU.S. Tsubaki DISCO is one of the most competitive traction drive units on the market today.

DISCO combines compactness and simplicity with energy efficiency to ensure quiet operation and long,trouble-free performance.

Starting with materials of the highest quality, U.S. Tsubaki carefully manufactures and assembles DISCO according to strict quality control and efficient manufacturing processes.

■ Speed stability

DISCO uses precisely machined parts. This provides very low speed drift underchanging loads or over long periods ofoperation; speed is stable right throughoutthe range, with very little noise or vibration.

Comparison of speed stability

The unique construction of DISCO minimizes the number of parts required,yielding a lightweight, compact design—thesmallest in its class.

■ High efficiency & long life

To achieve long-term, high torque capacityand wide speed variation with low surfacepressure, DISCO employs a planetarydesign utilizing specially formulated syntheticlubricants.

Comparison of mechanical efficiency

DISCO is constructed to allow for constantpressure, eliminating backlash and providinggood shock resistance. This allows you to useDISCO with confidence in situations requiringfrequent start/stop cycles or reversing.

Variable Speed MechanismThe secret to the dependability of DISCO lies in its simple construction.

� DISCO basic construction � Speed variation arrangements

(a) Output shaft at minimum speed

1. Power transfer

Power is transferred through the route shown bythe thick dotted line in the diagram. First, therotation of the input shaft (12b) is transferred tothe inner sun with hub (43), and then the innersun (44). The inner sides of the circular parts ofthe planets (42) are pushed by both suns by theforce of the dish spring (46), and the outer sidesare pressed against the outer ring and outer ringwith cam.

When the suns rotate, the planets revolve in afixed orbit as shown in the drawings (a) and (b).The sintered bearings (41), fitted into thegrooves of the planet carrier (25), transmit therotation to the output shaft (23).

3. Power transmission

Power is transmitted via a traction drive through anoil membrane that forms between the groundcontact surfaces.

The low surface pressure on the contact surfacesassures long life. Planet positioning is the secret toachieving strength in this compact design.

2. Speed variation

Speed adjustment is achieved by modifying thegap � between the outer ring (35) and theouter ring with cam (32), and changing theradius of the planet’s orbital revolution.

The outer ring with cam has a special shape(32), holding the ball retainer (33) in place.Turning the speed control shaft (80a) actsthrough the speed control nut (80e) and thespeed control bolt (37) to move the outer ringwith cam in the direction of rotation. The cammoves only �� in the direction of the shaft,and changes the gap �.

� Calculation of required torque (T)

Determine the application torque requirement at the output shaft of the DISCO. If the horsepower requirement at the output shaft isknown, the torque can be calculated using the following formula. Check the torque requirement at both the highest and lowest rpmof your application.

T= 63,025 • PN

Where: T = Transmission Torque (in./lbs.)P = Transmission Power (hp)N = Maximum use speed for constant torque transmission (rpm)

� Determine the service factor (Sf) of the application

The type and frequency of load applied to the output shaft of DISCO combine to provide a required service factor (Sf). Determine the service factor (Sf) from the following table.

For long, trouble free DISCO operation, make sure to check every item carefully.

1.3 1.4 1.5

1.0 1.1 1.2

1 If application requires instant reversals, contact U.S. Tsubaki, PTUC Division.2 A mechanical protection device that slips at rated torque may be required.

� Calculate Design Torque (Td)

Multiply the required torque (T) by the required service factor (Sf) to obtain the design torque (Td).Td = T • Sf

� Preliminary Selection of DISCO

Refer to the “Table of Standard Characteristics,” pages D-55~D-56. The selected DISCO should:1. Be appropriate for the required speed range2. Have a torque capacity equal to or greater than the design torque (Td).

DISCO Shaft Torque ≥ Td

*Slow Starting: Precautions may be necessary to avoid overloading the DISCO. One effective measure is to insert a powder couplingor fluid coupling between the variable speed drive and the load. In addition, start the DISCO at the lowest output rpm.

� Input shaft speed check

Faster input shaft speed yields more efficient operation. The maximum input is 1800 rpm. If the input rpm is low, it may be difficult tochange the speed of the DISCO. Please contact U.S. Tsubaki when the input is below 100 rpm.

� Allowable overhung load/allowable thrust load

1. Overhung LoadWhen a sprocket, gear, or pulley is mounted on thehigh speed or low speed shaft of the DISCO, anoverhung load is applied. Refer to the “Table ofStandard Characteristics” (pages D55~D56) for theallowable overhung load. The value is given formounting in the center of the shaft length.

Allowable Overhung Load (lbs.) ≥ T • Cf • Lf

RT = Required torque (in./lbs.)Cf = Load connection factorLf = Load location factorR = Pitch radius of the sprocket, gear, etc. (in.)

Confirm the overhung load.

2. Thrust LoadRefer to the “Table of Standard Characteristics” (pages D-55~D56) of the selected DISCO to confirm that the thrust load is withinthe design limits. Thrust load is a force acting axially along the shaft. D

Long-life synthetic oil is used in the DISCO variable speed drive, virtually eliminating the need for oil changing. The drive is oiledsufficiently before being shipped, thereby allowing it to be used as it is on delivery. As mixing oils and use of incorrect oil can have aconsiderable effect on the characteristics and life of the DISCO, great care should be taken with regard to lubrication.

� Infinitely variable speed drive

Make sure to use the long-life oil specified by U.S. Tsubaki inthe DISCO variable speed drive.

Specified synthetic lubrication oil: Dubney Alpha Drive P32(Manufactured by Idemitsu Kosan)1

� Installation and handling precautions• Do not hang or carry the variable speed drive by its knob or speed control shaft.

� Direction of installation• Install as horizontally as possible (vertically for vertically mounted

types). The allowable ranges are illustrated at right.• If greater angles of installation are required, call U.S. Tsubaki.

� Location of installation• Install in a place with good ventilation and where maintenance and inspection can be carried out easily.

� Coupling• When connecting to other machinery using a coupling, make sure to center correctly. Incorrect centering shortens the life of the

couplings and can cause damage to the variable speed drive. (We suggest U.S. Tsubaki’s flexible coupling for this purpose.)• Try to minimize impact, vibration and thrust from connected equipment.• When mounting couplings, sprockets and pulleys, etc., on the input and output shafts of the DISCO, insert a bolt into the

tapped hole on the shaft and use a jack screw. Excessive hammering will damage the bearings or the inside of the variable speed drive.

� Operation• Do not turn the knob when the drive is stopped.• When starting the drive with a full load or with large load inertia, start at as low a speed as possible.• Make sure not to overload the drive.

� Changing the right knob to left• It is possible to change just the speed control knob without

removing the speed control head housing.• Remove the center screw with a Phillips screwdriver and remove

the knob.• Put the knob in the left-hand side of the speed control shaft and

the pin into the pin hole. (See the drawing on the right.) Makesure not to hit the pin too hard.

• Turn the Scale II side on the variable speed indicator nameplateto the front and screw down the mounting screws to complete reassembly.
