Abstract

A motor with output shaft is coupled to an input shaft of a planetary gear system inside a case which in turn is disposed in the winch drive. The output shaft of the transmission gear traverses the other end of the case and is connected to a web plate of the winch drum by means of a spline shaft. On one end of the winch drum, the casing for the transmission gear and the shield of the motor are interconnected and connected to a principle frame and the winch drum is journaled thereat through roller bearings using cylindrical surfaces of the case and the drum directly as races. The winch drum is journaled at the other end through appropriate bearings in the principle carrier frame.
