Definitions

  • the invention relates to a bearing for pins of cylinders or drums in printing machines, wherein the pin is received in at least one arranged in a bore of a side wall bearings.
  • Such bearings are already previously known in a variety of embodiments.
  • a storage for a cylinder of printing presses described in which a cylinder pin is received in a fixed bearing in a bore.
  • the pin is received by a one-piece inner ring, which forms the inner race for multi-row cylindrical rolling elements.
  • An associated outer ring which is fixed in a housing, forms the outer raceway for the rolling elements.
  • Such bearings for cylinders or drums of printing presses are often designed as eccentric bearings.
  • Such a bearing which has the features of the preamble of claim 1, goes out of DE 41 26 545 C2 out.
  • the Dreiringnach described therein consists of a connected to a pin of a blanket cylinder inner bearing ring of the inner bearing, which is provided with a pin concentric outer raceway.
  • the three-ring bearing further has in a bearing housing on an outer bearing ring of an outer bearing, with one to the bore of the bearing housing is provided concentric inner raceway.
  • a raceway for the inner bearing and the outer bearing bearing one-piece eccentric intermediate ring is provided, which is pivotable by lying outside of the bearing housing actuating means in the circumferential direction.
  • radial bearing rows are provided in the form of cylindrical roller bearing rows between the pin connected to the inner bearing ring and the eccentric intermediate ring on the one hand and between the outer bearing ring and the eccentric intermediate ring on the other hand, in addition to a cylindrical roller bearing row at least one axial end thrust bearing rows, z.
  • ball bearing rows or funnelrollenaxiallager in the inner bearing or ball bearing rows in the outer bearing for separate recording of axial forces are arranged.
  • Such eccentric bearings can be used particularly advantageously in the printing industry whenever a plurality of printing cylinders are juxtaposed with their lateral surfaces touching. Due to the adjustable eccentricity of the individual bearings, the cylinders can be set exactly to each other, so z. B. tolerances are compensated in a simple manner.
  • the invention is therefore based on the object to avoid the disadvantages and a rolling bearing for the pins of cylinders or to provide drums in printing presses, which easily has an improved flexural rigidity.
  • this object is achieved according to the characterizing part of claim 1, characterized in that in the bore of the side wall a bearing bush is received in the through-bore bearing a first support bearing is arranged spaced from the axially spaced outside the bearing bore a second radially adjustable support bearing is, wherein the second support bearing is received by a housing which is releasably connected to the side wall and thus slidably connected thereto.
  • the housing is connected at two opposite circumferential locations, each with a bolt which is received in each case by a bearing block, which with fastening screws on the side wall 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 on at least one of the bearing blocks, a screw is arranged to be acted upon by a displacement force, wherein the adjusting screw is held in a receiving part which is held by fastening screws on the side wall. If only one of the bearing blocks is acted upon by the adjusting screw, the bearing is displaced virtually around 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, then the second support bearing in its entirety is displaced uniformly on both sides.
  • the second support bearing according to claim 5 is to be included in the housing on one side of a radially inwardly facing flange, which is connected via fastening screws with this. From claim 6 shows that the bearing bush has a radially outwardly facing flange with through holes are guided by the fixing screws for fixing to the side wall. According to another additional feature according to claim 7, the second support bearing should be formed as a multi-row cylindrical roller bearing.
  • the sealing of the bearing according to the invention is described, wherein according to claim 8 between the bearing bush and housing and according to claim 9 in the region of the flange of the housing per a seal should be arranged.
  • the first support bearing should also be formed as a multi-row cylindrical roller bearing, which may be an eccentric bearing according to claim 11.
  • the first support bearing is according to claim 12 on the Pin held by a lock nut and has according to claim 13 also has a seal.
  • the in FIG. 1 shown printing cylinder 1 has the multi-stepped pin 2, which is held on the first support bearing 3 and the axially spaced second support bearing 4 in the side wall 5, 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 has the radially outwardly facing flange 9 at the right-hand end, which is provided with through holes 10, so that the bearing bush 8 by means of fastening screws 11 in the bore 12th the side wall 5 is held.
  • the first support bearing 3 is formed as a three-row cylindrical roller bearing, roll its guided in cages 13 cylindrical rollers 14 on associated raceways, which are formed on the one hand by the inner ring 15 and on the other hand by the inner circumferential surface of the bearing bush 8.
  • the support bearing 3 is sealed on the left side by the seal 16 and held on the right side on its inner ring 15 with the lock nut 17 on the bearing pin 2, wherein the locking nut 17 can be fixed by the pin 18 on the pin 2 at the desired location is.
  • the support bearing 3 has an eccentrically formed bearing bush 8, the axis 19 is offset from the axis 6 of the pin 2.
  • the second support bearing 4 is axially spaced from the first support bearing 3 outside of the bearing bore 7 received in the housing 20, which is connected via its flange 21 by means of fastening screws 22 with the bearing outer ring 23.
  • second support bearing 4 further include the bearing inner ring 24 and guided in the cage 25 cylindrical rollers 26.
  • the sealing of the second support bearing 4 on the left side by the sliding seal 27, between the end faces of bearing bush 8 and the housing 20 on the bearing outer ring 23 is arranged sitting.
  • the seal also includes the sealing ring 28, which closes the gap formed between the flange 21 and pin 2.
  • the housing 20 is connected at two opposite circumferential locations, each with a pin 29 which is received in each case 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 holes 32 in the bearing block 30.
  • the adjusting screw 33 is arranged, which is housed in the receiving part 34 which is connected via fastening screws 35 with the side wall 5.
  • the pivot point in or on the right side bearing block 30 is to be sought.
  • a further adjusting screw 33 on the right side via the bearing block 30.
  • a shim In the gap formed between the bearing block 30 and receiving part 24 after adjustment may optionally be inserted a shim.
  • the described support bearing concept can be used either on one side or on both sides of the printing cylinder 1.
