摘要： With a motor having a motor housing and a motor shaft, a sleeve of predetermined length is mounted on the motor shaft with a proximal end of the sleeve engaging against a bearing that is mounted in the motor housing and supports the shaft for rotation. The bearing and the sleeve function to simplify the construction of the motor by eliminating a retainer ring and its associated annular groove from the shaft that were previously necessary to hold the shaft and bearing in relative positions, and by eliminating an additional retainer ring and its associated annular groove from the shaft that were used as a locator to positively locate a machined surface on the motor housing relative to the shaft and to positively locate a rotating component on the end of the shaft.
