Definitions
- the invention relates to a bearing for journals of cylinders or drums in printing machines, the journals being received in at least one roller bearing arranged in a bore in a side wall.
- Such bearings are already known in a variety of designs.
- DE 42 24 318 C2 describes a bearing for a cylinder of printing presses, in which a cylinder journal is received in a bearing fixed in a bore.
- the pin is received by a one-piece inner ring, which forms the inner raceway for cylindrical rolling elements arranged in several rows.
- An associated outer ring which is fixed in a housing, forms the outer raceway for the rolling elements.
- the three-ring roller bearing described there consists of an inner bearing ring of the inner bearing connected to a pin of a rubber blanket cylinder, which is provided with an outer race which is concentric with the pin.
- the three-ring roller bearing also has an outer bearing ring of an outer bearing in a bearing housing, which is connected to the bore the bearing housing is provided concentric inner raceway.
- a one-piece eccentric intermediate ring which supports the raceway for the inner bearing and the outer bearing and which can be pivoted in the circumferential direction by actuating means located outside the bearing housing.
- radial bearing rows in the form of cylindrical roller bearing rows are provided between the inner bearing ring connected to the pin and the eccentric intermediate ring on the one hand, and between the outer bearing ring and the eccentric intermediate ring.
- rows of ball bearings or crossed roller axial bearings in the inner bearing or rows of ball bearings in the outer bearing for separate absorption of axial forces are arranged.
- Eccentric bearings of this type can always be used particularly advantageously in the printing industry if a plurality of printing cylinders are arranged next to one another with their lateral surfaces touching one another. Due to the adjustable eccentricity of the individual bearings, the cylinders can be adjusted exactly to each other. B. tolerances can be compensated in a simple manner.
- the invention is therefore based on the object of avoiding the disadvantages described and a roller bearing for the pins of cylinders or to provide drums in printing presses that have improved flexural rigidity in a simple manner.
- this object is achieved according to the characterizing part of claim 1 in that a bearing bush is accommodated in the bore of the side wall, in the continuous bearing bore of which a first support bearing is arranged, from which a second radially adjustable support bearing is arranged at an interval outside the bearing bore is, wherein the second support bearing is received by a housing which is detachably connected to the side wall and thus slidably connected thereto.
- the two axially spaced support bearings alone achieve a much better bending stiffness of the cylinder connected to the pin compared to only one support bearing. Due to the radially adjustable second support bearing, a bending moment can also be applied to the pressure cylinder, which leads to a desired pre-bending. In this way it is ensured that a largely straight bending line can be achieved in cooperation with adjacent cylinders when the printing press is operated. This in turn results in constant pressure forces over the entire cylinder length, which have a positive effect on the print quality, especially at high cylinder speeds. In other words, the radially adjustable support bearing achieves a pre-bending of the printing cylinder, which counteracts the deformation during the printing operation by the cylinder pressure forces involved.
- the housing is connected at two opposite circumferential points with a bolt each, which is received by a bearing block, which is attached to the cable with fastening screws. tenwand is held, wherein according to claim 3, the diameter of the fastening screws is smaller than the diameter of the associated holes in the bearing block.
