Handwheel or handcrank for fixing on rotary shaft e.g. for machine tool to cylindrical sleeve and compression ring for clamping handwheel or handcrank

摘要

The handwheel (1) or handcrank is secured to a shaft (2) via a screw (13) screwed into the end face of the shaft, with the axial force transferred to a cylindrical sleeve (4) around the end of the shaft and a compression ring (8), acting against a stop edge (7) provided by the shaft.The compression ring is made of an elastic material with a slit which is reduced as the screw is tightened, with an inclined surface acting against a corresponding surface at the end of the sleeve, to provide a radial clamping force for the handwheel or handcrank
