Abstract
Bearing fretting conditions are eliminated in washing machines by providing a drive system in which the bearings are not loaded during the spin mode. The drive system includes an input shaft and first and second hubs rotatively mounted about the input shaft. The second hub is movable along the input shaft between a first position adjacent to the first hub and a second position displaced from the first hub. The drive system spins the washing machine's basket when the second hub is in its first position and oscillates the agitator when the second hub is in its second position. A brake disk is mounted to the second hub for movement therewith, and a brake surface is fixedly mounted to the washing machine adjacent to the brake disk so that the brake disk contacts the brake surface when the second hub is in its second position. Separation of the two hubs is accomplished by ball bearings which are unloaded when the second hub is in its first position.
