Glossary of TermsAngular Misalignment - A measure of the angle between two shafts. Theangle of error between two shafts is the amount of angular misalignment.

Axial Misalignment - A change in the gap between the shaft ends fromtheir position when the coupling was installed. Also called end float.

Backlash - The amount of free movement between two rotating mating parts.If one half of an elastomeric coupling or universal joint is held rigid, the otherhalf can be turned a slight amount. The freedom of movement, or looseness,is the backlash and may be expressed in degrees, or in thousandths of aninch. Backlash is not the same as stiffness or windup.

Donut - The elastomeric element in Centaflex and Saga couplings.

Drop out - The spacer coupling is often referred to as a dropout coupling.The dropout section is the portion that fits between the coupling hubsand is approximately equal in length to the space between shaft ends.It can be removed or “dropped-out” without disturbing the driving ordriven equipment.

Elastomer - Resilient materials through which the power is transmitted.They are in some way attached or mated to the coupling halves. They areusually made of rubber, synthetic rubber, or plastic materials.

Flex Links - Metallic, flexible members of “all metal” couplings such asDeltaflex which take the place of elastomeric elements. Power is transmittedthrough these metallic members and they provide for angular, and some-times parallel, misalignment.

Inserts - The elastomeric flexing element of the coupling. An insert maybe referred to as a spider, load cushion, sleeve, donut or elastomerdepending on the function or history of the product line.

Load Cushion - Rectangular blocks made of synthetic rubber and certainplastics, which are the elastomeric element in type ‘C’ and ‘H’Jaw couplings.

Open Center - A type of spider with a hole in the middle that allows theshafts of the driver and driven to be positioned within a short distance.

Parallel Misalignment - A measure of the offset between two shafts.Catalog information shows the angular and parallel misalignment tolerablein each coupling group. Both extremes should not exist if the alignmentis within the bounds stated.

RSB - Rough Stock Bore, also called pre-bore.

Runout - A measure of the amount that a cylindrical body is off its truecenter. When a coupling half is rotated on its shaft, the outside diameter ofthe coupling may be slightly “off to one side”. A dial indicator, whichmeasures movement in thousandths of an inch, is used to measure runout.Runout or eccentricity is expressed as Total Indicator Reading (TIR).

Sleeve - The elastomeric element in VIRTUS ES type couplings. Thisterm is also used to describe the flexible element which contains the internalteeth on a Gear coupling. This type of sleeve is either continuous or flanged.

Spacer - The portion of a flexible coupling or U-joint which spans the gapbetween ends of the shafts. Spacer couplings are used when the distancefrom one end of a shaft to the next is greater than the distance between anormal coupling spacing. The “normal” spacing of shafts when a jaw typecoupling is used is approximately equal to the thickness of a spider or lengthof the jaw. Special “spacers” may be used when the shaft spacing cannot bebridged by a standard coupling.

Spider - The elastomeric element of a flexible coupling, usually with 4or 6 “legs”.

Standards - Tolerances set by a variety of organizations around the world,such as:

ANSI - American National Standards InstituteASME - American Society of Mechanical EngineersSAE - Society of Automotive EngineersDIN - Deutsche Industrial NormenJIS - Japanese Industrial StandardAGMA - American Gear Manufacturers AssociationNEMA - National Electric Manufacturers AssociationIEC - International Electrical Code

Tightening Torque - The torque required to properly seat a set screw,cap screw or bolt in an assembly of any kind. Applied to a set screw, forexample, it is the force applied to the wrench multiplied by the approximatelength of the wrench in inches or feet. Catalog and instruction sheet valuesfor tightening torque are provided for most VIRTUS products.

Tolerances - The allowable variation in nominal dimensions specified.For example the tolerance in a bore may be plus .001 ( One thousandthsof an inch.) If the nominal bore is .875 (7/8 ) and the tolerance of .001 isadded, then:

.875

+.001 .876

Thus the allowable dimension of the bore would be .875 /.876 .

Torsional Stiffness - A measure of the torque required to create anamount of deflection about the coupling axis of rotation. It may be visualizedas a twisting action. It is most obvious in couplings which transfer torquethrough rubber or plastic elements; although, “all metal” couplings such asDeltaflex or gear couplings also twist under applied torque. Stiffness isexpressed in in-lb/radian.

Windup - The amount of twist of the coupling measured as an angle perunit of torque.

IMPORTANT SAFETY INSTRUCTIONS

WARNING

■ When using VIRTUS products, you must follow these instructions and take the following precautions. Failureto do so may cause the power transmission product to break and parts to be thrown with sufficient force tocause severe injury or death.

-Refer to this VIRTUS Catalog for proper selection, sizing, horsepower, torque range, andspeed range of power transmission products, including elastomeric elements for couplings.Follow the installation instructions included with the product, and in the individual productcatalogs for proper installation of power transmission products. Do not exceed catalogratings.

-During start up and operation of power transmission product, avoid sudden shock loads.Coupling assembly should operate quietly and smoothly. If coupling assembly vibrates ormakes beating sound, shut down immediately, and recheck alignment. Shortly after initialoperation and periodically thereafter, where applicable, inspect coupling assembly for:alignment, wear of elastomeric element, bolt torques, and flexing elements for signs offatigue. Do not operate coupling assembly if alignment is improper, or where applicable,if elastomeric element is damaged, or worn to less than 75% of its original thickness.

-For variable speed drives, variable speed pulley rim speeds must never exceed 10,500feet per minute. Companion pulley speeds beyond the ratings contained in this catalogare not recommended. For Fixed Center Drives, do not start until a torque arm bracket isinstalled. Failure to install torque arm bracket will cause torque arm to rotate rapidly andmay cause severe injury from moving parts. Do not attempt to disassemble spring loadedpulley because parts may be thrown with sufficient force to cause injury or death.

■ Do not use any of these power transmission products for elevators, man lifts, or other devices that carrypeople. If the power transmission product fails, the lift device could fall resulting in severe injury or death.

Engineering Data

A Brief Tutorial on MisalignmentThe function of a coupling is to connect driving and driven equipment. Inaddition, a coupling serves to protect costly equipment from the effects ofmisalignment, shock loads, vibration and shaft end float. Of these factors,the most common is misalignment and end float (also known as axialmisalignment).

Misalignment is a condition created by two shafts whose axes are not inthe same straight line. There are three forms of misalignment: parallel,angular, or the combination of the two. End float is the relative motion oftwo shaft ends.

Parallel misalignment occurs when the axes of the connected shafts areparallel, but not in the same straight line (fig. 1). Angular misalignmentoccurs when the axes of the shafts intersect at the center point of thecoupling (fig. 2). End float occurs when one shaft moves along it’s axisrelative to the other shaft. (fig. 3)

Misalignment can result from a combination of manufacturing tolerances,poor installation practices, thermal growth or shrinkage, foundationmovement, and/or component wear. The combination of angular andparallel misalignment within a system may be more detrimental to thecoupling and equipment than either of the individual misalignment. Axialmisalignment- result of either thrust loads, reaction loads, or heatgenerated movement - compounds the problem. Understanding theamount of misalignment that the coupling must handle or installing acoupling where it exceeds a maximum rated misalignment can result inpremature coupling failure and/or significant equipment damage.

Misalignment and Coupling FailureThe life expectancy of a coupling is affected by the degree of misalign-ment. The larger the misalignment, the shorter the life of the coupling asshown in fig.5. Misalignment may causes heat generation, fatigue, andan increase in wear in bearings of the drive and driven components.

When Misalignment Can Not be MeasuredWhen it is not possible to measure the misalignment of a system, or indesigning a new system, the following method can be used to estimateangular, parallel and combined misalignment. Each type of misalignment isfirst calculated and then the results are combined.

To calculate the maximum angular misalignment, the distance (L) and angle(a) must be known or estimated (see example below). First, calculate theangular misalignment noting the critical plane or midpoint of the shaft ends.Second, using the maximum parallel misalignment, be sure to consider bothhorizontal and vertical directions (Fig.3). Maximum parallel misalignmentoccurs when the shafts are diagonally opposed. Third, combine the results.

FIGURE 1

FIGURE 2

FIGURE 3

FIGURE 4

Worked exampleCalculate the worst possible composite alignment misalignment when:

α1 max = ±0.4°α2 max = ±0.4°

L max = 3 in. L max = 75 mm (LH and RH shafts)P1 max = 0.008 in. P1 max = 0.2 mmP2 max = 0.008 in. P2 max = 0.2 mm

1. Worst possible angular misalignment (Fig. 1) = α1 + α2= 0.4° +0.4°= 0.8°

2. Maximum radial misalignment (Fig. 2) = R1 + R2Since α1 and α2 are equal, R1 = R2Calculate for 2(R1) = 2 (tan α1 x L)= 2 (tan α1 x L) = 2 (tan 0.4 x 75)= 2 (tan 0.4 x 3) = 2 (0.007 x 75)= 2 (0.007 x 3) = 1.05 mm= 0.042 in.

3. Maximum parallel misalignment P3 (Fig. 3) = √P12 + P22

= √0.0082 + 0.0082 = √0.22 + 0.22

= 0.0113 inches = 0.28 mm4. Worst possible misalignment (Fig. 4) RC = R1 + R2 + P3

= 0.042 + 0.0113 = 1.05 + 0.28= 0.0533 in. = 1.33 mm

Note: How relatively minor angular misalignments can produce dis-proportionate radial misalignments. In this example, they account forapproximately 80% of the worst possible composite misalignment.

Summary

Worst possible angular misalignment = α1 + α2 (Fig. 1)Maximum radial misalignment = R1 + R2 (Fig. 2)Maximum parallel misalignment √(P12 + P22) = P3 (Fig. 3)Worst possible composite radial misalignment RC = R1 + R2 + P3 (Fig. 4)

Figures 1 through 4 represent that α1 = α2 and P1 = P2, and that L is the samefor LH and RH shafts.

Overhung LoadsAn overhung load is a bending force imposed on a shaft due to the torquetransmitted by V-drives, chain drives and other power transmissiondevices, other than flexible couplings.

Most motor and reducer manufacturers list the maximum values allowablefor overhung loads. These values should be compared with the loadactually imposed by the connected drive.

Weights of the drive components are usually negligible. The formulas arebased on the assumption that the load is applied at a point equal to oneshaft diameter from the bearing face. Factor F, shown at right, depends onthe type of drive used.

Inch example:Find the overhung load imposed on a reducer by a double chain drivetransmitting 7 HP @ 30 RPM. The pitch diameter of the sprocket is 10 in.;service factor is 1.3.
