ABSTRACT:
Clamping assemblies are disclosed for clamping together two members which fit concentrically one within the other, such as a hub and shaft arrangement. In one type of construction there is an inner taper ring, an intermediate taper ring and an outer taper ring each having one or more taper surfaces. Altogether, there are at least two pairs of interacting taper surfaces. The taper angle of one of the pairs of surfaces is within a range of angles in which self-locking takes place while the taper angle of the other of the pairs of taper surfaces is greater than the angle at which self-locking takes place. A plurality of axially oriented clamping bolts axially clamp the intermediate taper ring against the inner and outer taper rings, and the vertexes of both taper angles of the intermediate taper ring are both located on the same side of the intermediate taper ring. Also, the clamping bolts grip that one of the taper rings having the taper angle located within the self-locking range. In another type of clamping assembly there is an inner member, such as a shaft end, with an end face and a coaxial recess in the end face in which recess a taper clamping arrangement is provided for clamping an outer member to the inner member. The coaxial recess in the inner member is of cylindric shape, and the taper clamping arrangement includes at least an outer, double taper ring having a pair of inner surfaces formed as oppositely directed taper surfaces with the greatest wall thickness in the center of this outer ring. There is also a pair of inner taper elements each with an outer taper surface cooperating with one of the inner surfaces of the outer taper ring.
