Definitions

  • the invention relates to a bearing for a pressure cylinder equipped with a slide-on sleeve.
  • a bearing for a printing cylinder (DE-PS 37 15 536) is known, in which a jaw chuck is arranged displaceably on the printing unit side wall, in which a bearing seated on the journal of the printing cylinder is held in the operating state and can be moved apart and through via the diameter of the sleeve adjustable stops in the holding position for the printing cylinder is adjustable.
  • the expandable jaw chuck including the necessary drive mechanism, requires a relatively large amount of space in the radial direction of the printing cylinder, which is however only available to a very limited extent in a multi-cylinder arrangement in a printing unit.
  • the straight guides for the jaws require a relatively high manufacturing effort.
  • the invention has for its object to provide a bearing for a pressure cylinder equipped with a push-on sleeve according to the preamble of claim 1, which enables easy-to-manufacture, space-saving means to change the sleeve in the rotary printing press and a reliable, adjustable support of the journal of the Printing cylinder guaranteed in the operating state.
  • the pivotable support body including its storage, are simple to manufacture with relatively little effort and require little space for pivoting, so that they can also be installed in a corresponding number in a multi-cylinder arrangement.
  • the supporting bodies can be designed most favorably as cams or as eccentrics according to claims 2 and 3, whereby, in each case by circumferentially flattening the supporting bodies according to claim 4, the free space required for a sleeve change in the region of the opening of the frame wall with a small pivoting angle is favorable Support body can be realized.
  • the arrangement of the support body in pocket-shaped recesses of the frame wall according to claim 5 ensures stable storage of the support body and their accommodation in a tight space.
  • one of the side walls of the recesses as an insertable cover segment according to claim 6, supporting bodies equipped with axle journals on both sides can be easily and stably stored and easily installed.
  • the continuous ring groove according to claim 9 is particularly easy to manufacture.
  • Claim 10 eliminates the additional storage of the appropriately trained support body and enables a favorable compensation of the support forces.
  • the embodiment mentioned in claim 12 allows an effective actuation of the support body with few transmission elements in a narrow space and can therefore be used particularly advantageously in a multi-cylinder arrangement in a printing unit.
  • the adjustable stop according to claim 13 in its special design according to claim 14 enables adjustment of the support body in the operating state in a simple manner depending on the pressure cylinder position.
  • the separate control of the movements of the support body according to claim 18 allows their movement to be optimized depending on the respective load condition of the bearing. For example, the two most heavily loaded support bodies should at the end be turned simultaneously and in opposite directions and in the same way, but first turned off.
  • the support bodies asymmetrically in relation to the load, asymmetrically to the journal, in the sense of a uniform force distribution.
  • the curved recesses on the circumference of the bearing bush for the axle journal each enable a reduction in the surface pressure between the support body and the bearing bush and, if necessary, their additional anti-rotation protection, for example with respect to an additional eccentric bushing.
  • FIG. 1 shows a side view of the journal 1 of a pressure cylinder 2 (FIG. 2), on which a ball bearing 4 carrying a bearing bush 3 is arranged.
  • the bearing bush 3 is supported by three approximately symmetrically arranged, in each pocket-shaped recesses 5 of a frame wall 6 of the rotary printing press support body supported in the form of eccentrics 7, the mutual, coaxial journal 8; 9 in each case in the walls 10; 11 of the frame wall 6 are mounted (FIG. 3), a wall 10 being designed to ensure the assembly of the eccentrics 5 as a cover segment 12 inserted into the frame wall 6 and screwed to it.
  • a lever 13 On the outside of the frame wall 6 protruding journal 8 of the eccentric 7, a lever 13 is attached (Fig. 3), on which a pressure-operated working cylinder 14 is articulated (Fig. 1), its stroke and thus the pivoting movement of the eccentric 7 by one of a the lever 13 serving as a set screw 15 and a stopper 17 which is penetrated by it in a threaded bore and fastened to the frame wall 6 body 16.
  • Fig. 2 shows a sleeve 18 to be pushed onto the pressure cylinder 2, the inside diameter of which compared to the outside diameter of the circumference on both end faces with a run-up slope 19; 20 equipped, the centering of the sleeve 18 when sliding bearing bushing 3 ensuring a clearance between the two is larger.
  • the support bodies are pivoted back into the frame wall 6 until the opening, which is larger than the outer diameter of the sleeve 18 and is designed as a wall bore 21, is completely released.
  • the pressure cylinder 2 is supported on the opposite side in addition to storage in a known manner, not shown.
  • the gap between the bearing bush 3 and the wall bore 21 is covered against contamination by a plastic sleeve 22 which is elastically deformable when the sleeve 18 is changed and is fastened to the frame wall 6.
  • FIG. 4 and 5 show a, from a pocket-shaped recess 23 in the frame wall 6 I positively guided on the circumference while ensuring the slidability, with different radii of curvature and a flattening 24 which facilitates the sleeve change, designed as cams 25 and supporting body which is not supported on one side , analogous to FIG. 3 via a lever 13 I connected to a working cylinder 14 I journal 26. Due to the function, the recess 23 is closed on this side with a cover segment 27 inserted into the frame wall 6 I and screwed to it.
  • FIG. 6 and 7 show a variant with an externally placed on the frame wall 6 II and screwed to this ring 28, which is equipped with the eccentric 7 I receiving pocket-shaped recesses 29.
  • the eccentric 7 I mounted on both sides in the frame wall 6 II or the ring 28 are equipped with a movement mechanism corresponding to FIG. 1.
  • FIGS. 8 and 9 in which the ring 28 is provided with the frame wall 6 III by separate, each with a pocket-shaped recess 30 for an eccentric 7 II screwed segments 31 is replaced.
  • FIG. 10 shows a section of a bearing bush 3 I equipped on the circumference with curved recesses 32, in which the respective eccentric 7 III is supported over a large area and thus with a lower surface pressure. Due to the associated positive locking in the circumferential direction of the bearing bush 3 I , the latter can be secured in a simple manner against rotation, for example with respect to an additional eccentric bushing.
  • the latter option can be used, for example, when implementing a printing cylinder on and off, while saving the additional adjustable eccentric bushing, including the adjusting mechanism, which would otherwise be required. If the pressure cylinder is adjusted via the support elements, their constant contact with the journal or its bearing bush, e.g. B. conveniently to secure by a synchronous movement of eccentrics equipped with the same eccentricity. An existing computer in the rotary printing press can also be used for this.
