Abstract

An improvement is described which provides self centering for the clamp spring disclosed in [*]. A resilient 0-ring is retained in a groove around the clamp washer to center the inner diameter of the dished clamp spring. This holds the clamp spring centered when its inner diameter reduces upon tightening the clamp. Fig. 1 shows the disk clamp in its free state prior to clamping. The clamp washer is held on a disk hub by a clamp screw. A resilient 0-ring is retained in a groove around the clamp washer. A small interference fit is provided with an inner diameter of the dished clamp spring to give concentric location prior to clamping. Fig. 2 shows the disk clamp compressed by the clamp screw.
