Abstract
A self-aligning bearing and end shield mount for an electric motor or the like. The bearing mount has a spacer with a hub through which the rotor shaft extends and fingers that seat within an annular locating groove of the rotor shaft for securing the spacer to the shaft. The spacer also has a thrust surface. A spring has a hub portion through which the rotor shaft extends and a ring surrounding the hub with resilient arms therebetween. The spring also has a bearing seat and a thrust plate seat. A self-aligning bearing is seated in a bearing socket in the end shield of the motor housing and in the bearing seat of the spring. A thrust plate is seated within the thrust plate seat of the spring with the thrust surface of the spacer running against a surface portion of the thrust plate.
