Movement of one cycle of the CP10-30 pinion on a CP Characteristics rack vs.SS3-30 (m3) on a m3 rack. One turn KHK stock CP racks and pinions are suitable in applications where very accurate One half turn 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)

 About CP Racks & Pinions The 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 Difference between CP10 and m3 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.

[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. • 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 400 stock gears.

 Features of Tapered Racks and Pinions

1. Easy adjustment of Backlash value Spur Generally, adjustment of backlash value is made by changing mounting distance (adjusting Gears the height of the motor shaft). The backlash of KHK stock tapered racks and pinions are adjustable only by moving the pinion axially. 2. Reasonable Prices The precision of KHK stock tapered racks and pinions are obtained by rationalization in the Gears production process with our cutting-edge technologies. This enables us to offer quality tapered Helical racks and pinions in the same price range as the CP racks and pinions. (KSRCPF and KSSC). Gears  Example of Comparison Internal 4° • 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) Racks

♦ 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 Tapered Pinion available as special orders. & Pinions CP Racks Moving the pinion axially by 1 mm changes the backlash by Tapered 0.05 mm.
