Abstract
A lubricant free low cost overload release clutch having a spring housing with an integral hub, a detector ring containing fixed detent bullets for engagement with springs in the housing on one side, and a bullet detent housing on the other side, together with spider cushion and shaft housing engaged for rotary turning with the bullet detent housing in response to the rotation of a shaft in the shaft housing. The release clutch responds to preset torque limits determined by spring tension. After a disengagement caused by excess torque, the clutch will reset by further rotation of the detent housing.
