Abstract
A self-centering drive system is provided in an automatic washer wherein the input drive shaft and the output agitator shaft are drivingly connected by a planetary gear system. A bearing system is provided for the output drive shaft to allow the output drive shaft to seek the best operating center with respect to the input drive shaft and a surrounding ring gear member. Reduced noise, bearing wear and cost advantages are achieved.
