CP Racks & Pinions

KHK stock CP racks and pinions are suitable in applications where very accurate

positioning in linear motion is required. For your convenience, we offer circular pitches of 2.5 to 20 mm and in lengths of 100 to 2000 mm. (FRCP is available to

4000 mm)

Characteristics

About CP Racks & PinionsThe reference pitch of a metric module is computed by multiplying the

number of module by π (3.14159). For example, the reference pitch of

m 3 rack is 9.425 mm (3×π). When using a rack and a pinion in a linear

motion application, the fact that the pitch is not an integral number pres-ents a difficulty in accurate positioning. This problem is solved by CP

racks and pinions where one rotation of a pinion moves it precisely 50, 100, 150, ... or 600 mm. The following table lists the main features. The following table lists the main features.

[NOTE 1] The catalog numbers in the above tables with a suffix of F have both ends machined so that they can be butted against each other to make any desired length. The items with (D) have mounting screw holes for easier assembly.

Pinions

• For safer handling and to prevent damage such as deformation, KHK stock CP racks have round chamfering on the corners of the top land of the gear tooth. This rounded chamfered shape is patented by KHK. Because it is effective for reducing noise, all of KHK CP racks have this chamfering treatment.

• Black colored products are KHK stock gears that have an applied black oxide coating for rust resistance; this ‘blackness’ is a product characteristic of KHK stock gears.

Calculation assumptions for Bending Strength

Calculation assumptions for Surface Durability (Except those in common with bending strength)

[NOTE 1] The gear strength formula is based on JGMA (Japanese Gear Manufactures Association) specifications. The units for the number of rotations (rpm) and the stress (kgf/mm2) are adjusted to the units needed in the formula.

[NOTE 2] The allowable bending stress at the root σ Flim is calculated from JGMA401-01, and set to 2/3 of the value in the consideration of the use of planetary-, idler-, or other gear systems, loaded in both directions.

2. Caution in Selecting Gears Based on Gear Strength

Racks Pinions

Definition of bending strength by

JGMA 401-01(1974)

The allowable bending strength of a gear is defined as the allowable tan-gential force at the pitch circle based on the mutually allowable root stress of two meshing gears under load. Example of the failure due to insuf-

ficient bending strength.

Definition of surface durability by JGMA 402-01(1975)

The surface durability of a gear is de-fined as the allowable tangential force at the pitch circle, which permits the force to be transmitted safely without incurring surface failure. Example of the defacement due to

insufficient surface durability.

The precision standards of KHK stock racks are established by us.

Please be sure to see the pages below when selecting.

3. Selecting Racks By Precision

a Pitch Error of Racks NOTE 2 (KKHKR001) → page 374b Precision of Rack Blanks NOTE 2 → page 375c Backlash of Rack Tooth → page 375

[NOTE 2] Convert CP to m (module) when reference is made to the data in the table. (m=CP/π)

a KHK stock CP racks are mated with CP spur gears having the same pitch. Since CP2.5 (m0.796), CP5 (m1.592) and CP10 (m3.183) are very close in size to m0.8, m1.5 and m3 respectively, the selecting the proper mating gear should be verified to make sure that the items are correct. Otherwise, complications could arise.

b KSTRCPF and KSTRCPFD Tapered Racks are mated with KKTSCP Spur Gears having the same pitch. They can also be mated with other spur gears, however, they can not be used as parallel axis gears due to the setting angles.

The gear strength values shown in the product pages were computed

by assuming a certain application environment. Therefore, they should be used as reference only. We recommend that each user computes

his own values by applying the actual usage conditions. The table be-

low contains the assumptions established for these products in order

to compute gear strengths.

401

a KHK stock CP racks are designed to give the proper backlash when

assembled using the mounting distance given by the formula below

(mounting distance tolerance of H7 to H8 required). The backlash val-

ues are given in the table on page 375. Make sure that the mounting

distance stays constant for the length of the rack.

b KKRGCP type of KHK stock ground racks have four surfaces ground

parallel to within 10~15μm. To maintain true angle, they should be mounted on high precision bases as shown below. It is even possible

to correct for the angular errors of racks by compensating the mount-

ing base. With recent increases in the requirement for zero backlash

linear drives, such accurate assembly as shown is becoming more important.

c If the racks are not secured properly to the base, they could shift dur-ing operation and cause unexpected problems. It is very important to

insure firm mounting by the use of dowel pins or similar devices.d Machined end type racks such as KSRCPF and KSRCPFD series

have the pitch tolerance of— 0.1/— 0.3 for modules less than Module

2.5, and — 0.1/— 0.4 for larger modules. If you try to connect the racks

without any space, the pitch at the connection will be too small and will cause problems. Please follow the following diagrams for assembly.

a Secondary operations can be performed on all KHK stock CP racks

except for the racks where the gear teeth are induction hardened. To

avoid problems of gear precision, do not reduce the face width. The precision of ground racks and racks with mounting holes may drop if

you do not exercise extreme caution during installation or while modi-

fying.b Pitch lines of racks are controlled by using the bottom surface as the

reference datum and over-pin measurements on tooth thickness. If

you machine the bottom surfaces, the precision of the racks may be affected.

c When connecting two racks, the machining of the mating ends re-quires careful consideration. The meshing will be poor if the pitch (CP)

straddling the connection has a positive tolerance. We recommend a

minus tolerance on pitch of at the connection. The below is an indica-

tion of pitch tolerance for each module.

d To use dowel pins to secure racks, attach the racks to the base and drill both simultaneously.

e KHK stock CP racks made of S45C and SCM440 (except for ground

racks) can be induction hardened. However, the precision of pitch is decreased.

f To be able to handle parts safely, all burrs and sharp corners should be removed after the secondary operations are done.

g If you are going to modify the gear by gripping the teeth, please ex-ercise caution not to crush the teeth by applying too much pressure.

Any scarring will cause noise during operation.

Example of Comparison

Moving the pinion axially by 1 mm changes the backlash by 0.05 mm.

• KSRCP5-1000 and KSSCP5-30 combination produces a backlash value of 0.1 to 0.26.• KSTRCPF5-1000 and KKTSCP5-30 combination produces a backlash value of 0.05

or less. (Target value)

♦ Note above backlash values are theoretical values when meshed under ideal conditions.

♦ Tapered racks and pinions are not interchangeable with KHK stock CP racks and pinions.

♦ Different modules, number of teeth, ground gear versions and custom-made items are

available as special orders.

The shaft angle illustrated below can be obtained by changing the assembly orientation of the tapered spur gear or by mating with a regular spur gear.

When mating a tapered rack and a tapered pin-ion, where each hub is set in opposite directions, a 0° shaft angle is obtained. (Axis Parallel).

When mating a tapered rack and a tapered pinion, where each hub is set in the same di-rection, an 8° shaft angle is obtained.

When mating a tapered rack and a spur gear, a 4° shaft angle is obtained.

1. Easy adjustment of Backlash value

Generally, adjustment of backlash value is made by changing mounting distance (adjusting the height of the motor shaft). The backlash of KHK stock tapered racks and pinions are ad-

justable only by moving the pinion axially.

2. Reasonable Prices

The precision of KHK stock tapered racks and pinions are obtained by rationalization in the

production process with our cutting-edge technologies. This enables us to offer quality tapered

racks and pinions in the same price range as the CP racks and pinions. (KSRCPF and KSSC).

[Caution on Secondary Operations] a Please read “Caution on Performing Secondary Operations” (Page 402) when performing modifications and/or secondary operations for safety concerns.

b Avoid performing secondary operations that narrow the tooth width as it affects precision and strength.


b If gear tooth hardening, or thermal refining, is applied, the decarburization layer (approx. 0.5 mm thickness) on the rectangu-lar surfaces cannot have the hardness you designate.

c Avoid hardening Racks with bolt holes, due to deformation occurring at the mounting hole and the difficulty of straightening the rack after hardening.

[Caution on Secondary Operations] a Please read “Caution on Performing Secondary Operations” (Page 402) when performing modifi-cations and/or secondary operations for safety concerns.

b If gear tooth hardening, or thermal refining, is applied, the decarburization layer (approx. 0.5 mm thickness) on the rectangular surfaces cannot have the hardness you designate.

c Avoid hardening Racks with bolt holes, due to deformation occurring at the mounting hole and the difficulty of straightening the rack after hardening.

b The backlash values shown in the table are the theoretical values when these gears and KSURCPF Racks are in mesh.

[Caution on Product Characteristics] a The allowable forces shown in the table are the calculated values according to the assumed usage conditions. Please see page 401 for more details.b Backlash of racks vary depending on mating pinions. Please calculate the backlash in accordance with the backlash of the mating pinion and values in the table "Back-

lash of Rack Tooth (Amount of Tooth-Thinning)" (Page 375).c For products made of stainless steel, heat treatment* and passivation ** solutions are applied. Passivation is a rust-resistance

treatment, but it is not effective on the machined surface and not a totally rustproof solution. *Heat Treatment Solution Heat treatment by the carbon formed on the surface during blank manufacturing is made to infiltrate the material interior. **Passivation Immersion of the metal in a nitric acid solution to make it more rust-resistant.d After attaching the racks to the base, please fasten with dowel pins. Clamping only with mounting screws could possibly cause the screws to be broken, due to a heavy load.

b Please avoid hardening Round Racks. It causes contortion and deformation, and straightening processes are difficult to apply.

[Caution on Product Characteristics] a The allowable forces shown in the table are the calculated values according to the assumed usage conditions. Please see page 401 for more details.b In cases of using a molded flexible rack in an arc shape, proper meshing cannot be obtained as the pitch error and the tooth profile error increases. Be sure and adjust

the center distance so that the pinion turns without any problem.c Metal Flexible racks are not suitable for use when positioning accuracy is required.d The tolerance of the height (C) is 0 to -0.15 and the tolerance of the width of the base (F) is 0 to -0.1.
