ABSTRACT:
A device for dismounting the neck bush (4), the bearing bush (5), and the chock (6) from the conically constructed region of the roll neck (2) of a roll (1), where a pressure shoulder ring (8), which is supported on the end face of the neck bush (4), is installed on a roll neck shoulder (3) of the roll (1), is to be improved in such a way that it can be built very short and that it can carry out the dismounting movement with very small pressures of a pressure medium. To this end, it is proposed that a gap (11) be provided between the pressure shoulder ring (8) and the end face (7) of the roll neck (2), that the pressure shoulder ring (8) be coupled with the neck bush (4), and that at least one pressure medium for removing the neck bush (4) and the chock (6) be provided in the gap (11).
