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.
  • a further feature of the invention according to claim 4 shows that an adjusting screw is arranged above at least one of the bearing blocks to act upon it with a displacement force, the adjusting screw being held in a receiving part which is held on the side wall by fastening screws. If only one of the bearing blocks is subjected to the set screw, the bearing practically shifts by a pivot point which is formed by the other bearing block. If, on the other hand, both bearing blocks are subjected to a displacement force, the whole of the second support bearing is displaced evenly on both sides.
  • the second support bearing in the housing is to be surrounded on one side by a radially inward-pointing flange which is connected to it by means of fastening screws. It is apparent from claim 6 that the bearing bush has a radially outward-pointing flange with through bores through which fastening screws are guided for fixing to the side wall. According to another additional feature according to claim 7, the second support bearing should be designed as a multi-row cylindrical roller bearing.
  • the seal of the type of bearing according to the invention is described, wherein according to claim 8 between the bearing bush and the housing and according to claim 9 in the region of the flange of the housing, a seal should be arranged.
  • the first support bearing should also be designed as a multi-row cylindrical roller bearing, which can also be an eccentric bearing according to claim 11.
  • the first support bearing is on the Pin held by a lock nut and also has a seal according to claim 13.
  • Figure 2 is a side view of the bearing arrangement according to the invention in the region of the second support bearing.
  • the pressure cylinder 1 shown in FIG. 1 has the multiply stepped pin 2, which is held in the side wall 5 via the first support bearing 3 and the axially spaced-apart second support bearing 4, so that it can rotate about its axis 6.
  • the first support bearing 3 is received in the continuous bearing bore 7 of the bearing bush 8, which on the right-hand end has the radially outward-pointing flange 9, which is provided with through bores 10, so that the bearing bush 8 with the aid of fastening screws 11 in the Bore 12 of the side wall 5 is held.
  • the first support bearing 3 is designed as a three-row cylindrical roller bearing, the cylindrical rollers 14 of which are guided in cages 13 and roll on associated raceways which are formed on the one hand by the inner ring 15 and on the other hand by the inner lateral surface of the bearing bush 8.
  • the support bearing 3 is sealed on the left-hand side by the seal 16 and held on the right-hand side via its inner ring 15 with the lock nut 17 on the bearing journal 2, the lock nut 17 being fixed at the desired location on the journal 2 by means of a pin 18. is xizable.
  • the support bearing 3 has an eccentrically designed bearing bush 8, the axis 19 of which is offset from the axis 3 of the pin 2.
  • the second support bearing 4 is accommodated axially spaced from the first support bearing 3 outside the bearing bore 7 in the housing 20, which is connected to the bearing outer ring 23 by means of fastening bolts 22 via its flange 21.
  • the second support bearing 4 which is designed as a double-row cylindrical roller bearing, further includes the bearing inner ring 24 and the cylindrical rollers 26 guided in the cage 25.
  • the second support bearing 4 is sealed on the left-hand side by the sliding seal 27, which is located between the end faces of the bearing bush 8 and the housing 20 on the bearing outer ring 23 is arranged seated.
  • the seal also includes the sealing ring 28, which closes the gap formed between the flange 21 and the pin 2.
  • the housing 20 is connected at two opposite circumferential points with a bolt 29, which is in each case received by a bearing block 30, which in turn is held on the side wall 5 via fastening screws 31.
  • the diameter of the fastening screws 31 is smaller than the diameter of the associated bores 32 in the bearing block 30.
  • the adjusting screw 33 is arranged above the left-hand bearing block 30 and is accommodated in the receiving part 34, which is connected to the side wall 5 via fastening screws 35.
  • the fastening screws 31 arranged in the two bearing blocks 30 according to FIG. 2 are first loosened, that is, they are slightly unscrewed from their threaded mounting hole in the side wall 5. If the adjusting screw 33 arranged in the receiving part 34 is now moved downward in the direction of the arrow, the bearing block 30 arranged on the left-hand side is also ten moves. This is possible because the diameter of the fastening screws 31 is smaller than the bore 32 in the bearing block 30, ie because a gap is formed between the two.
