ABSTRACT:
A lock washer for use with spring type retainer rings such as snap rings, axially coiled springs, and the like, which are adapted to be mounted in a spring-retained holding position upon a shaft or other cylindrical member within a circumferentially extending groove or back of a retaining shoulder, but which may be deformed in a generally radially outward direction to a released position with respect to the groove or shoulder. The lock washer comprises an annular body portion which is adapted for axial face engagement mounting with an associated retainer ring, and is fabricated to provide a plurality of integral bendable peripheral tabs which are bendable over peripheral edge portions of the retainer ring to form radial holding abutments for opposing deformation of the retaining ring to a released position. The bent tabs also serve to axially secure the retaining ring and the associated lock washer against axial separation.
