SHAFT POSITIONING AND COUPLING DEVICE

摘要

A shaft coupling device has a resilient shaft locking ring (12) with a tapered surface (28) engaged by a corresponding surface (46a) on an outer ring (14) such that axial compression of the rings (12, 14) (e.g. involving screw threads (28, 56) co-axial with the device) causes the ring (12) to contact and grip the shaft (18) and may cause the ring (14) to expand into the bore of a machine element (71) (e.g. a Vee-pulley sheave).
