Abstract

The drive is transmitted from a motor shaft via the coupling to a worm gear and a pinion on the output shaft. Excessive load on the machine causes a shaft to move slightly out of its location in its bearings. The coupling comprises two sets of friction discs, one set attached to the movable shaft and the other set attached to the casing of the coupling. A disc spring assembly presses the friction discs together, the pressure being transmitted via needle bearings. Excessive machine load compresses the spring, freeing the drive.
