Patent ID: 8820237

Claim:
A device for connection of an ink transfer roller in an inking unit or printing unit of a printing machine, the ink transfer roller having at least a roller body to which an end pin is connected at each end thereof, each end pin of the ink transfer roller being mounted to rotate in a bearing housing of the inking unit or printing unit in at least one hearing, in which at least one end pin of the ink transfer roller is splined to a shaft piece of a drive, said device comprising: an actuator located on a non-drive side of the device to effect a splined connection of the ink transfer roller to the shaft piece of the drive, with which the at least one end pin of the ink transfer roller is positioned against the shaft piece of the drive, the ink transfer roller including a half-coupling on both end pins thereof, and the half-couplings of the ink transfer end pins being shape-mated with corresponding half-couplings on the shaft piece of the drive and on the actuator; an axial bearing located on a drive-side of the device, the axial bearing being movable in an axial direction of the ink transfer roller; and a shaft bellows located between the drive and the axial bearing, the bellows being configured to compensate for axial offset transferred from the ink transfer roller to the axial bearing, the actuator being movable in the axial direction of the ink transfer roller so as to (i) effect the splined connection of the ink transfer roller to the shaft piece of the drive and (ii) enable an adjustment of a side register of the ink transfer roller by acting against the movable axial bearing.
