A hydraulic clamp for being mounted on a shaft. The clamp may comprise a clamp body; an aperture in the clamp body for receiving the shaft, the aperture extending in an axial direction of the clamp body from a first end to a second end; a recess formed in the clamp body and substantially surrounding the aperture, for receiving a pressure medium; the clamp body having at the first end a pressure cylinder communicating with the recess for pressurizing the pressure medium and thereby deforming the recess sufficiently to secure the clamp to the shaft; the pressure cylinder having a corresponding piston arranged for axial movement toward the second end for pressurizing the pressure medium. The piston and cylinder may be threaded such that rotation of the piston drives the piston into the cylinder toward the second end to pressurize the pressure medium. The piston may comprise a flange, disposed on the piston for engaging the clamp body for limiting axial movement of the piston toward the second end. The clamp body may further comprise a stop, disposed for engaging the piston and for limiting axial movement of the piston away from the second end. The stop may have an aperture arranged axially of the piston, the aperture permitting a tool to access the piston by being inserted generally in the axial direction. |
