ABSTRACT:
The output shaft of an electric motor is supported by a ballbearing mounted on the motor end plate. The outer race of the ballbearing is positioned in a cup having a semispherical portion. The motor end plate includes a socket portion to receive the semispherical portion of the cup. A retainer plate of spring metal is mounted on the motor end plate. A plurality of resilient finger-like extensions on the retainer plate press the outer race in the cup and the cup in the socket. The cup swivels in the socket. By reason of that, the outer race can be shifted with respect to the inner race, and the entire bearing can be shifted with respect to the motor end plate. A collar, containing a plurality of legs, the ends of which define a plane perpendicular to the shaft axis, is slid down the shaft. The legs pass through a like plurality of holes located in the end plate to contact the cup. Pressing the legs against the cup causes it to swivel in the socket until all the legs contact the cup. When this happens, the inner and outer races are coplanar and therefore aligned. The collar is then removed and filler material is injected into the holes to secure the cup in place on motor end plate.
