Cam type clutches
Cam-type cut-out clutches belong to the group clutches with automatic reengagement function.
In the cam-type cut-out clutch, spring-loaded cams radially engage special grooves in the housing. When the clutch torque is exceeded, the cams are pressed into a pair of spring-loaded shift rings as a result of vectorial force resolution and lock with them. When the reengaging speed of 180 to 300 rpm is reached, the cams slide back into their starting position.
The clutches only operate in one direction. Owing to the central spring arrangement, the clutch is not suitable for a through-mounted shaft. This design offers a low-cost alternative to the ball-type clutches.
