ABSTRACT:
A wrap spring clutch assembly is disclosed which is designed for use with a rotary element which is subjected to repeated intermittent rotary motion. The clutch assembly includes a first circular hub fixedly attached to the element for rotation therewith, a wrap spring mounted on the first hub and adapted to grip or release the hub depending on the direction of movement of a free tang of the wrap spring. A second, split hub acting as a resilient shock absorber is mounted on the rotary element and underlies a portion of the wrap spring so as to deflect inwardly when the wrap spring grips the first hub thereby permitting a small amount of additional rotation of the rotary element to provide a controlled deceleration of the rotary element, thereby absorbing the shock force of virtual instantaneous deceleration of the rotary element which otherwise occurs and tends to break the wrap spring at the juncture of the spring coils and the tang which is attached to the rotary element.
