Abstract
A locking washer for axles on vehicles that prevents a nut from rotational movement relative to the axle. The locking washer includes a sleeve step having central passage with a non-cylindrical section that is rotationally coupled to the axle. The non-cylindrical section may include polygonal lobes or splines that engage a matching shaped portion on the axle. The washer is engaged directly on the shaped portion of the axle instead of the threaded portion of the axle and thereby reduces manufacturing costs and steps by eliminating machining of the threaded portion. The washer being engaged on the shaped portion prevents any relative movements between the axle and the washer from disturbances such as vibration, impact, and rotation.
