An arrangement for fastening a roll ring (5) to an overhung roll shaft (1) by means of a taper sleeve (8) which transmits essentially the entire torque and which is loaded axially by a spring (43) supported on an abutment (47) adjustable on the free end of the roll shaft. The roll ring can be exchanged easily because of a cylinder part (21) arranged radially within the spring. This cylinder part forms a first annular cylinder space (40) for prestressing the spring, with which it interacts via a flange, and a second cylinder space (22) for drawing off the taper sleeve, to which it is connected via engagement means (28). The spring and the hydraulic devices can remain in place when a roll ring is assembled and removed, because their outside diameter is less than the bore of the roll ring. |
