Drawn Cup Roller Clutch
HF SERIES
Characteristic: Drawn cup needle roller clutch is a one-way clutch that consists of a thin-walled stamped outer ring with a series of ramps on the inner wall, a nylon cage, springs, and needle rollers.They transmit high torques in one direction and are particularly compact in the radial direction.There are two types of clutches: with and without bearings. Drawn cup needle roller clutch has a very high conversion accuracy, thanks to the fact that each needle roller has an independent reed, which guarantees continuous contact between the shaft, the needle roller and the ramp.Due to the light weight of the clamped needle rollers and the small moment of inertia, high conversion frequencies are allowed.They also have a small transcendent frictional torque.Drawn cup needle roller clutches can be used in a variety of app lications, such as
positioning clutches, backstop clutches and overtaking clutches. In these app lications, drawn cup needle roller clutch is available with an idling or locking function.
Drawn cup needle roller clutch without bearing : Needle roller clutch HF without bearing but can transfer torque.Drawn cup roller clutch HF with steel spring, but roller clutch KF use p lastic spring.
Note: When using a drawn cup needle roller clutch without bearing, the shaft must be aligned by a separate rolling bearing, otherwise a drawn cup needle roller clutch with bearing is required.
Knur led : Drawn cup needle roller clutch with outer diameter has the suffix R and are suitable for p lastic housings. The outer surface of the stamped bezel is fully or partially knur led axially.
Drawn cup roller clutch with bearing :The Needle Roller Clutch HFL has integrated p lain or rolling bearings and is therefore able to withstand torque as well as radial forces.
Drawn cup roller clutch HFL with steel spring, roller clutch KF use p lastic spring.
Knur led : Drawn cup roller clutch with knur led outer surface has the suffix R and is suitable for p lastic housings. The outer surface of the stamped bezel is fully or partially knur led axially.
Sealing : Drawn cup needle roller clutch is open at both ends
The shaft of the raceway must be hardened and ground. The raceway surface hardness must be 670 HV + 170 HV and the hardening depth CHD or SHD must be large enough (CHD 0.3 mm). The chamfer of the shaft end face must be machined to approx. 1 mm and 15 °. The design of the shaft is shown in the table below.
