Definitions

  • the invention relates to a roller bearing for rollers in printing units of a printing press, in particular for storing inking rollers, dampening rollers or the like in an offset rotary printing press according to the preamble of claim 1.
  • a roller bearing is described herein, which consists of a vertical opening in a plane of the roller axis, an open top receptacle that can be connected to the frame of the machine, and a hold-down device that can be rotated about the roller axis, so that the roller bearing is rotated by rotating the ring trained hold-down device can be opened in order to insert the roll neck into the receptacle which is then open at the top and to be able to close the roll bearing by turning the hold-down device back.
  • a ball bearing is placed on the pin at the roller end, which is inserted into the open receptacle and held in place by turning the hold-down device.
  • Such a roller bearing can be closed relatively quickly and is easy to open, but is unsuitable for high-speed machines due to the required bearing play and is at high risk of contamination, which impairs the function.
  • the rotatable hold-down device has play due to manufacturing tolerances, so that the roller bearing also has play in the receptacle, but this should be avoided because it impairs the ink transfer.
  • a safeguard against opening in the direction of rotation is explained in the document, but the unauthorized twisting in the opposite direction is not secured, so that an opening by simple vibrations is possible or when the machine runs backwards, as is customary in creep speed.
  • a hold-down ring causes problems because of the limited space available.
  • a roller bearing with a roller lock in which a bearing ring is fitted onto the pin arranged at the end of the roller, which has a guide pin flattened on two sides and with this guide pin through a slot from above into a round one Inserted and secured in place after rotation by a spring pin.
  • Such a roller bearing is also to be equipped with an eccentrically effective adjusting device in the case of high demands on the print quality, in order to compensate for the play necessary for the removal and reinstallation for moving the bearing parts relative to one another.
  • the invention has for its object to provide a simple roller bearing constructed from as few individual parts as possible, which results in a safe, play-free roller bearing in a confined space even at high speeds and enables the rapid removal and error-free reinstallation of rollers in printing units of printing presses.
  • the invention solves this problem by a roller bearing with training features according to claim 1.
  • a roller bearing with the features of the invention is largely contamination-free and can be used both for fixed pins on the roller end and for roller bearings placed on the pin end. No changes need to be made to the roll neck. No adapter pieces are required.
  • a roller lock with the new training features can be used universally.
  • the roller bearing according to the exemplary embodiment consists of a receptacle 2, which can optionally be fixedly connected to an adjustable rocker 1 or also directly to the frame of the machine, the hold-down device 3 and the bolts 4 connecting the two.
  • the receptacle 2 is formed on the end face of a bearing body 5 which faces the roller and which in turn can be connected to the frame 1.
  • the receptacle 2 has in the lower region an upwardly open support surface 6 for the pin 7 formed at the end of the roller or for a bearing 8 plugged onto this pin.
  • the support surface 6 extends over a predetermined angular range.
  • the hold-down device 3 is arranged diametrically opposite one another, which also has a circular support surface 9 on its underside, which lies from above either against the pin 7 or against a bearing 8 fitted onto this pin.
  • the hold-down device and the receptacle thus enclose the pin or the bearing over a certain circumferential area, which ensures secure mounting, and are radially braced against one another by a spring.
  • the hold-down device 3 and the receptacle 2 are connected to one another by the bolts 4 arranged in a bore of the bearing body 5 that runs radially to the roller axis and are braced against one another by plate springs 10 attached to the bolts 4.
  • the clamping forces can be adjusted by screwing the nut 11 onto the bolt 4.
  • the hold-down device 3 and the bolt 4 are connected to one another in a rotationally fixed manner by a screw 12 or other means.
  • a tool is connected at the end to the head 13 of the bolt 4, which tool can be inserted, for example, into a hexagon socket 14 of the bolt head 13.
  • the hold-down device 3 can be pivoted 90 times, so that it releases the bearing 8 or the pin 7 to the side in order to lift it out of the receptacle 2.
  • the pin 7 or a bearing 8 on the pin 7 is positively secured by the rounding of the hold-down device and the receptacle.
  • To open the hold-down device must be raised by the amount of curvature of its support surface 9 in the axial direction of the bolt 4. Accordingly, an axial movement of the Bolt 4 required.
  • a gap is provided between the underside of the hold-down device 3 and the adjacent surface of the bearing body 5, so that the hold-down device and the bearing body do not touch on this surface when the bearing is closed.
  • a roller bearing in the design described enables simple, quick and safe operation by 90x swiveling of the hold-down device and positive locking of the roller journal when the roller bearing is closed.
  • the spring forces acting radially in the roller bearing are controllable. Incorrect operation due to too tight clamping and possibly plastic deformation of the parts of the roller bearing are therefore excluded.
  • the roller bearing with the features of the invention does not require any adaptation of the roller pin or of a bearing fitted onto this roller pin, so that both fixed roller pins and rotating roller pins can be clamped by the roller bearing. There is not only a defined position of the hold-down when the bearing is open, but above all there is a clear engagement of the hold-down when the bearing is closed. Finally, it is particularly advantageous that axis angle errors are compensated for by the resilient clamping.
  • the positive connection is not carried out by the rounding described in the hold-down device 3 above the bearing 8 or the shaft journal 7, on which the bearing 8 is attached, but by a corresponding design between the hold-down device 3 and the bearing body 5 with the recording.
