Abstract
The invention concerns a coupling for the detachable connection of two components, preferably a shaft with a hub, which for transmission of a torque are rotatably connected with each other by form-fit. When using such plug or form fit connections such as between a roll journal and a coupling box in a rolling mill, large tolerances must be expected that express themselves in peripheral directions and have adverse effects on the surface integrity of the rolled material. The invention provides for a clamping element which preferably can be inserted in the hub, acted upon by hydraulic fluid to keep the shaft in place relative to the hub. The clamping element is of a two-part design and can be filled with hydraulic fluid through appropriate devices, so that the hub is tightly fastened on the shaft upon assembly. For removal of the hub from the shaft, the pressure in the clamping element is simply relieved.
