Lock nut washer for a locking nut assembly

摘要

A single lock nut washer formed of steel or other material to simultaneously lock an inner wheel bearing nut and an outer bearing nut secured to an axle spindle. An annular member has a plurality of outwardly extending tabs that bend over to engage the outer surface of the outer bearing nut to prevent rotation. An inwardly extending lug engages a groove in the axle spindle to prevent rotation of the washer. A plurality of circumferentially arranged bores are each adapted to receive a longitudinally extending pin of the inner bearing nut to prevent relative rotation. The lug is offset from the bores and is preferably oriented circumferentially intermediate one of the bores and a midpoint to an adjacent bore.
