CLUTCH DEVICE FOR ELECTRIC WINCH

摘要

A clutch device for electric winches comprises: a gear box positioned outside of the gear mechanism of the electric winches; an ring gear settled in the gear box and functions along with the gear mechanism; a plurality of braking recesses provided on the outer surface of the periphery of the ring gear; a breaking port provided on the gear box corresponding to the braking recesses; a detachable clutch sleeve fixed on the braking port; a reversed T shaped clutch lever provided in the sleeve; an elastic element provided on the clutch lever; and a clutch handle provided on the sleeve, which connects with the clutch lever by a connection, wherein, the inner top surface of the clutch handle and the up top surface of the clutch sleeve are cam faces formed by double tapered faces, a rotating-positioning mechanism which can be rotated at 180 degrees provided between the clutch handle and the clutch sleeve. The engaging and disengaging functions between the clutch lever and braking recesses of the ring gear can be realized by the rotation of the clutch handle in clockwise and anticlockwise direction. The construction of the present invention has the simplified construction. The rotation operation is laborsaving, convenient and safe. Operation miss and the lock of the clutch will not be appeared during the usage. It also has longer service life.
