ABSTRACT:
A torque limiting coupling for transmitting torque to a tubular member from a driving shaft extending axially throughout the tubular member, and more particularly for driving a conveyor roller from a power shaft, the torque limiting coupling comprising the driving shaft having a polygonal peripheral shape about its portion projecting through the tubular member, and a plurality of resilient spherical members disposed loosely in the tubular member between the peripheral surface of the polygonal portions of the shaft and the inner bore surface of the tubular member, the diameter of the resilient members being larger than the widest distance between the peripheral surface of the polygonal shaft portion and the inner bore surface of the tubular member.
