ABSTRACT:
A radially deformable clamping device including a cylindrical body having a central bore, a pair of inwardly extending annular grooves near the ends of the body and a pair of annular grooves extending outwardy from the central bore and spaced inwardly of the first pair of grooves. The grooves define a central portion and flexible zones to permit the central portion to be radially deformed. A plurality of equally spaced concentric axial bores extend from one end face of the body through the central portion. Slots extend between the plurality of bores and the central bore in the central portion. The bushing can be applied around the mandrel having a shoulder and a threaded end with a nut, the body being axially compressed between the shoulder and nut to cause radial deformation. A pin can be provided in one of the bores to prevent rotation of the body. In another embodiment, the plurality of bores extend entirely through the body and receive screws or bolts to cause the axial compression.
