Abstract
A thrust bearing assembly for absorbing forces on an input shaft of a washing machine is described. In one embodiment, the thrust bearing assembly is located at an upper end of the input shaft just below a pinion gear coupled to the shaft. The thrust bearing assembly includes a cage and bearing assembly positioned between washers. The thrust bearing assembly is supported on a bronze flange bearing having a bore, and the input shaft extends through the bore. The flange bearing is supported by the transmission housing, and a lubrication reservoir is formed by the transmission housing. The reservoir typically is filled with a lubricant. In operation, when the machine operates in the spin cycle, axial forces are transferred through an actuator cam, a pulley hub, and the shaft to the thrust bearing assembly. The trust bearing assembly cooperates with the transmission housing to absorb the downward axial forces on shaft.
