ABSTRACT:
A clamp secures disks to a hub through means of a push-on retaining ring which is engaged with a grip ring received in an annular groove extending around the hub. The grip ring is split and expansible to enable it to be engaged with, or removed from, the groove. Spaced detent grooves are formed in the external surface of the grip ring to provide different positions at which the retaining ring may be engaged with the grip ring to alter the degree of compression imparted to the disks by the retaining ring. The retaining ring may be pushed fully past the grip ring to release the clamp. An installation and release fixture is provided to selectively move the retaining ring over the grip ring.
