ABSTRACT:
A plastic pulley and stub shaft are integrally formed with one another and used as a unitary component in the drive train of a clothes washing machine. In the washing machine, an electric motor is used to drive both an agitator mechanism and a water pump of the washing machine. The pulley has a co-axial bore on one side for receiving a motor shaft of the electric motor. The pulley also has a circumferential groove configured for receiving a belt therearound which is, in turn, connected to the agitator mechanism of the washing machine. The stub shaft extends co-axially from the opposite side of the pulley as the bore. The stub shaft is configured for engaging an impeller of the water pump for driving the water pump. Thus, the electric motor is operatively connected to and drives both the agitator mechanism and the water pump via the integral plastic pulley and stub shaft component.
