Abstract
A disengageable universal shaft for rolling mill drives having a flange on the roll side that can be coupled centrally with the coupling sleeve attached to the roll shaft and a flange at the gear side that is connected with the drive via a spline shaft that enables the disengaging movement. The spline shaft is penetrated centrally by an extensible part of a piston-cylinder unit and is constructed at the output stub on the gear side. This output stub is enclosed by a longitudinally displaceable coupling bushing that is connected with the flange of the universal shaft on the gear side.
