Abstract
An overload clutch limits the transmittable torque moment by permitting an override when a certain compression force is exceeded. For this purpose a drive shaft meshes with a disk provided with a number of holes in which balls are received. The disk has an axial thickness smaller than the diameter of the balls so that the balls can be uniformly exposed to a compression force exerted by a compression spring through a disk or bushing bearing on the balls. The balls cooperate with an entraining cam disk. As long as the torque to be transmitted is smaller than the compression force, the balls engage cam ribs on the entraining disk and transmit the torque. When the input torque exceeds the compression force, the balls override the cam ribs.
