Shaft clamping assembly with concentric taper rings - has vertices of taper surfaces of intermediate taper ring and clamping bolts contacting ring taper within self locking range

摘要

The clamping assembly especially of a hub to an inner member in coaxial relation to a recess having a cylindric outer surface, especially a shaft, with an inner taper ring having a cylindric inner peripheral surface and an outer peripheral surface formed as a taper surface. An outer taper ring has a cylindric outer peripheral surface and an inner peripheral surface formed as a taper surface. An intermediate taper ring has inner and outer peripheral surfaces formed as taper surfaces interacting with the inner and outer taper surfaces of the other taper rings. The taper angle of the one pair of taper surfaces has an angular spacing from the self-locking angle in the self-locking range while the taper angle of the other pair of taper surfaces has at least the same angular separation above the self-locking angle. Clamping bolts axially clamp the intermediate taper ring against the inner and outer taper rings.
