Abstract

The sheave retention apparatus of the present invention includes a cap (34) that fits over the end (30) of an axle (12) to retain a sheave (10) thereon. A bolt (36) fastens the cap to the axle. Cap (34) is disk shaped with a shoulder (42) that fits over end (30) of axle (12). When installed, bolt (36) passes through an off-center hold (38) in the cap and into a corresponding off-center nut (40) welded to the inner wall of the tubular axle. Rotation of cap (34) on axle (12) will bind the cap between the bolt and the axle to prevent unthreading of the bolt. Addition­ ally, to resist unthreading under vibrational influences, a lock­ ing plate (62) that is clamped between the hexagonal head (60) of the bolt and the outer surface of the cap. The locking plate has two notched corners (68) and (70) that contact a portion of the cap to prevent rotation of the locking plate with respect to the cap, and has two square corners (64) and (66) that are bent up against the wrench flats of the bolt to prevent the bolt from rotating with respect to the locking plate.
