Definitions

  • the invention relates to a roller bearing for rollers of inking and dampening units on rotary printing presses according to the preamble of the claim.
  • a roller bearing of the type mentioned is known from DE-Gbm 1 995 046.
  • the roller receiving piece is designed as a stepped pin in the form of a plug-in bearing, a pin on the pin being axially displaceably mounted in the eccentric bushing.
  • These bearings have disadvantages in terms of operation because they require two-man operation or additional devices for holding the roller when it is inserted axially into the bearing point.
  • the object of the invention is therefore to enable a sensitive setting in a device of the type mentioned, in which a considerable reduction in the angle of rotation of the adjusting movement of the eccentric bushing relative to the rotation of the roller receiving piece is ensured.
  • the roller bearing according to the invention has advantages in terms of operation and, at the same time, enables the assembly or disassembly direction to be approximately maintained when the roller is adjusted.
  • the pin 13 of a transfer roller 1 carries a roller bearing 12 which is encased with a bearing ring 4.
  • the bearing ring 4 has, on opposite sides, a flattened, double-edged guide pin 14 which, together with the bearing ring 4 receiving the roller 1, is placed in a bearing body 20 of a roller receiving piece 3 which is open on one side and which has a slot S corresponding to the width of the flattened guide pin 14.
  • the roll holder 3 is provided with a pin 15 which is rotatably arranged in an eccentric bush 5 in the bearing block 6 on the side stands 19 of the printing press.
  • the pin 13 of the roller 1, the guide pin 14 of the bearing ring 4 and the pin 15 of the roller receiving piece 3 are aligned with one another with an axis 16, i. H. arranged coaxially.
  • the roller bearings 12, the bearing ring 4 and the bearing body 20 which is open on one side are also coaxial.
  • the guide pin 14 of the bearing ring 4 After inserting the guide pin 14 of the bearing ring 4, it is turned to the right or left. As a result, the curved part of the guide pin 14 moves into the bearing bore of the bearing body 3 that is open on one side until a resilient pressure piece 11 of the guide pin 14 engages in a recess on the bearing body 20 that is open on one side. Thus, the guide pin 14 is closed in the bearing body 20, which is open on one side, and secured against rotation.
  • the pin 15 of the roller holder 3 can optionally also be mounted directly in the side stand 19, or in a hinged on the side stand, not shown in the drawing, if the roller 1 is also to be pivoted on and off.
  • the receiving bore for the eccentric bushing 5 in the bearing block 6 is narrowly slotted so that the eccentric bushing 5 can be clamped there by means of a clamping screw 7 and at the same time secured against axial displacement.
  • the clamping of the eccentric bushing 5 in the bearing block 6 must first be carried out by actuating the Clamping screw 7 can be canceled.
  • the eccentric bushing 5 can then be rotated by means of a dowel pin via the holes 17 assigned to the circumference.
  • the pin 15 of the roll receiving piece 3 is frontal in Montage placed. Disassembly direction provided with a groove 18, equal to the position of the slot S.
  • One end of an anti-rotation lever 8 engages in the groove 18, in the manner of a sliding joint.
  • the anti-rotation lever 8 has z. B. the shape of a flat iron with a corresponding guide in the groove 18. With its other end, this lever 8 is pivotally mounted about a pivot point parallel to the pin 15 by means of the pivot joint 10 in the bearing block 6.
  • the slot S of the open-ended bearing body 20 rotates and thus also the assembly and disassembly direction of the roller 1 only slightly by half the angle ⁇ .
  • the assembly or. Disassembly direction by the angle ⁇ when the eccentric bushing 5 is rotated by 180 degrees, e.g. left to right in a lateral direction.
  • the device according to the invention thus allows a sensitive adjustment of the roller 1 with respect to the roller 2, with a minimal change in the assembly or disassembly direction of the roller 1.
  • the roller 1 is also securely, precisely and free of wear.
  • the anti-rotation device according to the invention with the components 3, 5, 6, 8, 10, 18 could be understood as a vibrating crank loop with a modified thrust joint shape 18 in relation to the movement sequence, in which the eccentric bushing 5 represents a special form of a crank which is located in the side stand 19 is clampable.
