ABSTRACT:
An overload release clutch having a driving rotor mounted on an input shaft and a driven disk mounted on an output shaft. A shuttle rotor having saw-tooth shaped teeth on its perimeter rides on a splined hub which is an integral part of the driving rotor and engages complementary teeth on the perimeter of the driven disk. Laminated leaf springs are held in position by means of rocker bars which insure that no portion of the torque is transmitted through the leaf springs. In the buckled state, the leaf springs exert a compressive force against the shuttle rotor to maintain it in full mesh with the driven disk during the engagement cycle. Disengagement occurs when a sudden increase in torque in the output shaft causes the driven disk to rotate and force the shuttle rotor axially upward until the buckled leaf springs snap "overcenter" and hold the two toothed members apart. The clutch is reset by manually forcing the shuttle disk downward to rebuckle the leaf springs and thereby hold the toothed members in engagement as before.
