Abstract
A device for changing a roll disk arranged in a free-floating fashion on a roll shaft and braced against a shoulder of the roll shaft, the device including a roll shaft piece connectable to an end face of the roll shaft and having radially projecting claws. An installation-and-removal unit is placeable on and coaxially turnable to the roll shaft. The unit has radially extending first, second and third claws that form perimeter segments. The first claws correspond to and engage with the claws of the roll shaft piece. A taper bushing is slidably provided between the roll disk and the roll shaft to hold the roll disk on the roll shaft, and has radially extending claws. The second claws correspond to and engage with the taper bushing claws, and are also moveable axially to the roll shaft. A ring is coaxially mounted on a side of the roll disk facing the unit, and has radially extending claws that correspond to and engage behind the third claws. All the claws have a perimeter extension whereby the corresponding claws lie perimetrically next to one another in a plane seen in the axial direction when the unit is placed on the roll shaft. The unit is turnable between a first position in which the claws of the roll shaft piece and the taper bushing respectively engage with the first and second claws, and a second position in which only the claws of the ring engage with the third claws.
