Abstract
A compact and rugged drive mechanism for a winch of high pull rating is disclosed featuring a cycloid drive of powerful construction which serves to provide a driving connection between a cable drum and a reversible motor driven, two stage chain and sprocket drive to an input drive shaft. The cycloid drive includes a ring gear and cycloid gear in meshing engagement with the ring gear. The cycloid gear is supported for eccentric rotation within the ring gear. A clutch pin is releasably secured in fixed relation to the ring gear and a fixed housing to prevent ring gear rotation during normal power-in and power-out modes of operation under cable load. Controlled free spooling of the drive mechanism is effected, when desired, upon removing the clutch pin to render it inoperative.
