Abstract
A coupling includes a shaft at least partially inserted into a hollow shaft and a ring part, in particular of a clamping ring, slipped onto the hollow shaft. The ring part is axially restricted by a collar provided on the shaft, in particular a radially projecting collar, and/or the ring part is resting against a collar, or the collar, of the shaft, in particular against a collar provided on the shaft, in particular a radially projecting collar. The hollow shaft has slots, in particular axial slots, which are set apart from the collar. The ring part has a chamfer, in particular on its inner side and/or at its ring opening and/or in particular in its axial end region facing the collar, so that the inner diameter of the ring part in the axial region covered by the chamfer is greater than the inner diameter in the particular axial region in which the ring part is in contact with the hollow shaft. The ring part has a radially uninterrupted threaded bore into which a screw part, in particular a set screw and/or a threaded pin, is screwed, which exerts pressure on the hollow shaft.
