Abstract
A transmission for a washing machine includes a housing, an agitator shaft rotatably mounted to the housing, and an input shaft rotatably mounted to the housing. A one-way clutch connects the input shaft and the housing which permits relative rotation between the input shaft and the housing in a first direction and prevents relative rotation between the input shaft and the housing in a second direction. An agitation system connects the input shaft and the agitator shaft whereby rotation of the input shaft relative to the housing provides back-and-forth agitation of the agitator shaft. A one-way clutch ball bearing rotatably and axially supports the housing. The one-way clutch ball bearing is a sprag type-clutch which prevents rotation of the housing in the first direction and permits rotation of the housing in the second direction.
