NUT LOCKING MEANS A locking arrangement is provided for retaining a nut, such as a spanner nut, locked in position on a shaft. The nut has a plurality of equally spaced apart apertures in one axial face thereof. An arcuate key is provided with a pair of apertures spaced apart the same distance as the apertures in the nut. The key has a projecting tang lying in the plane of the key and extending radially toward the center of said arcuate key. The radial centerline of the tang is offset from the centerline lying midway between the apertures in the key. With the apertures in the key aligned with two apertures in the nut, and with the tang positioned in a slot in the end of the shaft, bolts are passed through and tightened in the aligned apertures whereby the nut is locked in position with respect to the shaft. |
