The invention relates to a bearing arrangement () for a part to be mounted such that the part rotates about an axis, such as a cylinder, roller, drum or shaft, comprising at least one rolling bearing (), which is accommodated in a bearing housing (), which is mounted movably in an arrangement housing () in a linearly movable manner by at least one linear guide (), and also including an actuation device () for effecting a linear shifting movement of the bearing housing perpendicularly to the axis between a rest position and a working position. The actuation device includes at least one prestressed spring element, which presses the bearing housing into the working position, and at least one hydraulic or pneumatic device for generating a restoring force acting counter to the spring element for moving the bearing housing into the rest position.

Bearing arrangement

A device for driving a cylinder () of a printing machine has an electric motor () whose rotor () is arranged coaxially with respect to the cylinder () and is firmly connected so as to rotate with the latter, and whose stator () is held on a frame construction () in which the cylinder () is mounted such that it can be displaced axially. The rotor () and the stator () are dimensioned and coupled to the cylinder () and the frame construction (), respectively, in such a way that during any axial displacement of the cylinder () possible during the operation of the printing machine, the gap () formed between stator () and rotor () remains constant both with regard to gap width (s) and with regard to length.

Direct drive for a printing machine

A bearing arrangement for opposite journals of cylinders, rolls or drums having actuators that permit a displacement of the cylinders, rolls or drums in a direction perpendicular to an axis of rotation of said cylinders, rolls or drums, each of said journals being received in a frame wall via a rotary bearing for being placed against and removed from said frame wall whereby a centered rotary bearing () is received in a bearing housing (), the bearing housing () is arranged through a linear bearing unit () on a connecting structure () for longitudinal displacement relative to the connecting structure (), and the connecting structure () is connected to the frame wall ().
