ABSTRACT:
An overload clutch comprising a driving part and a driven part releasably interconnected in torque transmitting relationship by balls, held in a cage in engagement with torque transmitting recesses of the parts and which can be disengaged by relative rotation between the driving and driven parts when the torque to be transmitted exceeds a predetermined value and in which spacers are moved by the cage into spacing relationship with the parts to maintain the balls out of engagement with the recesses after disengagement with the clutch, and wherein the clutch can be re-engaged by relative rotation between the parts in the reverse direction to that which caused disengagement by the provision of two pairs of inter-engageable abutments and a first control means to prevent inter-engagement of one pair of the abutments as a result of relative rotation when the clutch is disengaged and to permit of inter-engagement of the abutments of the other pair on resetting by relative rotation in the reverse direction, and second control means to maintain the abutments of both pairs out of inter-engagement during the initial stages of disengagement of the clutch.
