ABSTRACT:
A releasable hub-shaft connection mechanism, in particular to be used in heavy machinery for transmitting strong torques, has a shaft, a hub surrounding the shaft and at least one bore with its axis parallel to the shaft and located at the junction of the shaft and the hub so as to penetrate each equally. A bushing with a cylindrical outer face and a conical inner face is accommodated in the at least one bore, and a tapering bolt is axially displaceable in the bushing, by means of this bolt the bushing is expandible. At a closed bottom end of the bushing, where the bushing has the smallest inner diameter, a further bore extending through the bushing to the outside is located and is connectable to a pressure medium conduit. The tapering bolt is displaceable from a clamped into a release position when the further bore is supplied with a pressure medium from said pressure medium conduit.
