Abstract
A washing machine appliance includes a rotatable wash basket and an agitator rotatably mounted within the wash basket. A rotor of a motor is selectively coupled to the wash basket and the agitator through a transmission assembly. The transmission assembly includes a planetary gear train including a plurality of helical gears. An input shaft is fixedly attached to the rotor and is operably coupled with the planetary gear train. A thrust bushing or bearing is positioned around the input shaft and a spring element is positioned between the thrust bushing or bearing and the rotor to prevent axial movement of the input shaft caused by the helical gears engaging each other when the direction of rotation of the input shaft changes.
