Clamping ring securing tool or workpiece to shaft - is hollow sleeve with thin walled section deflected by internal hydraulic pressure onto tool etc.

摘要

The assembly consists of tool (1) screwed to the face of ring body (3) fitted in a sealed manner to the other part (5) of the ring body. The two parts are mounted together by bolts (6) and the division surface is sealed by ring seal (14). Within the body of the complete ring a hollow space (7) is created with a relatively thin wall (4) adjacent to the surface of shaft (2). At one point of the outer wall of the jacket a non-return nipple (8) is provided. When hydraulic pressure is applied on this nipple, wall (4) deforms with a curvature towards the shaft surface and provides a positive locking of the ring on the shaft.
