Shaft or ring clamping and positioning device, has hollow ring firmly connected with shaft and has compression chamber connected with device for producing and controlling medium, where chamber has circular clamping surface for fixing shaft

摘要

The device has a hollow ring (3) firmly connected with a shaft (1) or a ring, where the hollow ring has a compression chamber (17) flexibly deformable by a fluid medium. The chamber is connected with a device for producing and controlling the fluid medium and has a radially arranged circular clamping surface (4) for fixing the shaft or the ring in a fixed counter surface (25). The chamber is formed of two symmetrically or asymmetrically arranged half rings (6, 7) and has a pressure channel.
