Abstract
A bearing lock is provided that improves upon existing methods of stabilizing a bearing in an electric motor. The bearing is fit between a rotatable shaft and a nonrotating annular support. The bearing has an inner race surrounding the rotatable shaft and has an outer race surrounded by the annular support. The bearing lock has an annular body with a midportion, an inner wall, and an outer wall. Both the inner wall and the outer wall extend generally in a first direction from the midportion and are spaced from one another to define an annular cavity therebetween. The outer wall has circumferentially-spaced integral tabs that extend at least partially toward the inner wall to provide a biasing force to lock the body to the annular support when the annular support is placed in the annular cavity.
