Kr-sc-4.0 ball indent torque limiter
In case of overload, the ratchet parts balls leave their indentations, and a relative motion between the driving and driven side is produced. In this way damages due to overload are avoided. The shaft ring makes an axial motion to the shifting way "s" and activates the limit switch or proximity initiator, the signal can be used for control functions or for disconnection of the drive. For the restartáit would reach after the overload eliminated the ball which was rotating in the keeping rotating vest automatically in the next indentation then the driving and driven side was returning normal rotation with an angle returned mutual.
