ABSTRACT:
Disclosed is an improved clamping device for keyless mounting of a hub on a shaft of the type comprising an inner wedge ring having a cylindrical inner surface for gripping the shaft when contracted and an outer wedge ring having a cylindrical outer surface for gripping the bore surface of the hub when expanded. The pair of wedge rings have interracting annular surfaces with matching shallow-angle tapers and at least one has a stable dry anti-friction material coated thereon. The pair of wedge rings placed in the annular space between the hub and shaft are engaged with axial force means to cause the outer wedge ring to expand and the inner wedge ring to contract and thereby lock the hub to the shaft. The improvement is each of the wedge rings being provided by an equal number of a plurality of circumferential sectors separated from each other by a rotational stop member to provide maximum rotational securement of the hub to the shaft and substantially reduced circumferential deflection of the wedge rings under load.
