Arrangement for stabilizing an excentric bearing bush for a printing cylinder bearing, in a bearing hole which rotatably receives the bush in a printing press side frame.

摘要

For moving a printing cylinder to and from its operating position its journal stub is carried in an excentric ring (5) via a bearing, said ring being in turn rotatably mounted in a bearing hole (7) in the side frame of the printing press. The outer surface of the ring (5) has a basically circular shape. The hole (7) is circular. The outer surface of the ring (5) is ground off along a lesser circumferential portion. The junctions (S) between the circumferential portions of the ring (5) form support ridges, by means of which the ring (5) rests against the wall of the hole (7). A motor (20) ensures that the ring (5) rests, via the junctures (S), against the hole wall (7). The junctions (S) are situated just outside the limits for the range of movement described by the resultant to the forces which are transferred from the ring (5) to the hole wall (7).
