Abstract
A clamping ring for clamping a member such as a rotor on a shaft comprises a ring member formed by a plurality of ring segment portions which are displaceable relative to each other in the peripheral direction of the ring member, and spring elements disposed in the respective gaps between adjacent ring segment portions, thereby connecting the ring segment portions together. The clamping ring is fitted into an opening in the member such as a rotor, and the clamping action is produced by a variation in the inside and/or outside diameter of the ring member, by virtue of the ring segment portions being displaced relative to each other in the peripheral direction only in the plane of the ring member.
