Bearing for printing roller of printing machine; has two bearing units, one for radial and axial support of roller with devices for axial adjustment, and second for radial support of roller

摘要

The bearing has a first bearing unit (2) for radial and axial support of the roller and a second bearing unit for radial support of the roller. The roller is held and supported on both sides by both bearing units. At least one bearing unit, preferably the first, also has devices (4) for axial adjustment of the roller. The first bearing unit has a first support (5) for axial and radial support of a first shaft part (6) relative to a first casing (7) and a second support (8) for radial support of a second shaft part (9). The second support enables an independent axial displacement of the second shaft part with respect to the first shaft part. The second bearing unit has a third support for radial support of a third shaft part and a fourth support for axial support of the third shaft part. The fourth support is arranged so that it is axially displaceable relative to a second casing by an axial spring element. The first shaft part, the second shaft part, the roller and the third shaft part are non-rotatably fixed together. The fourth support, the third shaft part and the roller are axially displaceable relative to the second casing.
