Definitions

  • the invention relates to a bearing for cylinders of a printing machine according to the preamble of the first claim.
  • Such a bearing is known from DE-OS 2 837 557.
  • This camp has several advantages. For example, absolute play-free storage of the cylinder liner in the frame is possible. Changes in torque due to the influence of thermal expansion are not to be feared when the bushing is actuated during pressure changeovers.
  • the plastic material of the bearing ring has a shock-absorbing effect. The stick-slip effect is avoided. There is little friction and self-lubrication, which results in a certain freedom from maintenance.
  • the disadvantage is that a play-free pairing between the bores in the frame and the flange bearing has to be selected in a complex measuring technique. It is also necessary to manufacture the bearing ring with high precision in the predetermined thickness, which is difficult with plastic.
  • a decisive disadvantage is that because of the poor thermal conductivity of the full-surface bearing ring made of plastic, there is a risk that the thermal conductivity will also deteriorate in the entire bearing area.
  • This disadvantage generally also occurs with the plastic-coated circular guides known in practice, into which a sliding coating, e.g. made of curable synthetic resin is pressed over the entire sliding surface of a sliding pair, usually onto the shorter guide part, or applied in some other way.
  • the object of the invention is therefore to provide an absolutely suitable bearing for cylinders of printing machines of the type mentioned, which with simplified manufacture and Easier installation makes it possible to maintain the thermal conductivity in the storage area.
  • the bearing according to the invention has many advantages.
  • the heat can flow freely in front of and behind the plastic bearing ring. Up to a temperature difference of 5 ° Celsius between the bearing and the frame, the function of the print shutdown is still completely flawless, i.e. there is no change in torque.
  • the thermal expansion in the bearing has no effect on the cylinder liner.
  • the bearing is already sufficiently free of play even if the operating temperature is not reached.
  • the plastic material of the bearing ring has a very strong vibration damping and the known emergency running properties are given. Since the expansion of the material of the bearing ring is greater than that of a metallic bearing material, e.g. Is cast, the cylinder bearing is slightly preloaded at operating temperature. This bearing is insensitive to pressure strips. Last but not least, the manufacture and assembly is facilitated, so that the customer can also spray out the service.
  • a flange bearing 3 is arranged in a bore 7 of the frame 5 or within a ground steel bushing of the frame 5 provided with a bore 7 on a cylinder liner 2.
  • the cylinder journal 1 slides in the cylinder liner 2.
  • the cylinder liner 2 and / or the flange bearing 3 are drilled eccentrically.
  • An approximately 25 mm wide annular groove 9 is screwed into the center of the bearing surface of the flange bearing 3, the width of which is thus considerably smaller than the depth of the bore 7 in the frame 5.
  • a pasty plastic is pressed into the annular groove 9, which hardens to a finished bearing ring 6 in the bearing, the bore 7 being pretreated with a release agent 10 Bores 8 are arranged in the flange bearing 3 for pressing in the pasty plastic.
  • Suitable as pasty plastic e.g. a hardenable synthetic resin for sliding guides.
  • the production or mode of operation can be briefly summarized as follows:
  • a release agent 10 is applied to the inner wall of the bore 7 in the frame 5 or in the steel sleeve of the frame 5 beforehand. With the help of the injection holes 8, the pasty plastic is now injected. After about 8 hours of curing, the flange bearing 3 can be pulled will. Additional reworking of the diameter is not necessary.
  • a cylinder bearing is produced in a simple manner that minus the release agent thickness of 3 to 4 ⁇ m is an absolutely suitable cylinder bearing, the flange bearing 3 remaining easily pivotable in the swivel joint 4.
