Definitions

  • the invention relates to a main drive according to the preamble of claim 1.
  • a known drive of this type (DE-OS 26 37 795) already uses two spur gears per printing unit, which are in direct engagement. Each of these spur gears meshes with a drive spur gear of the two plate cylinders, the drive spur gears of the two plate-displacement cylinder pairs also being able to engage.
  • This known main drive already enables an optimal rotation-free, low-play and low-wear drive of the rubber-rubber printing units, but is complex due to the double drive of each printing unit and allows a defined flow of force without special adjustment only if the drive wheels of the two rubber cylinders do not mesh with one another.
  • the object of the invention is to provide an optimally rotationally error-free, low-play and low-wear main drive, with any diameter of the main spur gears, with a simplified technical structure and with a defined power flow in the drive wheels.
  • the drive of the rubber-rubber printing unit according to the invention by means of only one drive spur gear achieves a simplified structure of the main drive.
  • the diameter of the main spur gears can also be freely determined so that the distance between the printing units can be adapted to the requirements.
  • the drive is carried out without tensioning the spur gears involved and nevertheless a defined power flow is always achieved within the drive.
  • the slanted position of the two plate cylinders per printing unit is also made easier with the claimed solution. By eliminating the tension, higher powers can be transmitted with the same dimensions of the drive wheels.
  • claims 2 and 3 characterize further simplifications of the spur gear drive, it proving particularly advantageous that only one clutch is required to decouple the printing units compared to two clutches with mutual electrical locking in a drive via 2 plate cylinder drive wheels.
  • the exemplary embodiment according to FIG. 1 shows a web-fed offset printing press which consists of the printing units 1, 2 and 3.
  • the paper web 4 is guided through this approximately horizontally in the direction of the arrow.
  • the paper web 4 receives the printing units from a roll carrier, not shown. After printing, it can be dried using a drying unit. e.g. processed in a folder.
  • the machine shown is a so-called rubber-rubber machine, in which the paper web is passed and printed between the offset cylinders 5, 6.
  • Each of the two offset cylinders 5, 6 works together with a plate cylinder 7, 8.
  • the upper plate cylinder 7 is assigned a drive spur gear 9 which engages with the main spur gear 10 of the main drive. In the same way, the drive could also take place via the plate cylinder 8.
  • main spur gears 10, 11 are provided per printing unit, which mesh with the main spur gears of the respectively adjacent printing unit.
  • the main spur gear 11 of the printing unit 1 is in engagement with the main spur gear 10 of printing unit 2, which in turn meshes with the main spur gear 11.
  • the same engagement conditions also exist between the printing units 2 and 3, the main spur gear 11 of printing unit 2 also meshing with the main spur gear 10 of printing unit 3.
  • the main spur gears are driven by a drive motor, not shown, which motor can be assigned to any printing unit.
  • a drive spur gear 13 is located in another wheel alignment on the journal 12 of the plate cylinder 7, which drives the plate cylinder 7 to the rubber cylinder 5 via a further spur gear 14.
  • the drive spur gears 14 and 15, which are engaged, are on the Axle journal 16 of the two offset cylinders 5 and 6 arranged.
  • the drive spur gear 17 of the plate cylinder 8 is in engagement with the drive spur gear 15 of the offset cylinder 6, the drive spur gear also being fastened on the axle journal 18 of the plate cylinder 8 here (FIG. 2).
  • each printing unit accommodates the bearings for the cylinders and rollers.
  • the inking cylinders 20 and dampening units 21 are assigned to the plate cylinders 7.8.
  • the two offset cylinders 5 and 6 can be pivoted in their bearings in such a way that they can be turned on and off against the two plate cylinders 7 and 8 and also against one another.
  • An inclination of the plate cylinders can be carried out via the bearings of the plate cylinders.
  • the bearings provided for this are not shown in the drawings.
  • the drive spur gear 9 is also provided with a circumferential register adjustment, not shown, with which the two pairs of plate cylinders and offset cylinders can be rotated.
  • the two main spur gears 10, 11 of the main drive are mounted on the side frame 19 via roller bearings 22 and journals 23.
  • the diameters of the two main spur gears 10, 11 in the exemplary embodiment shown are approximately 540 mm and together correspond approximately to the distance between the printing units 1, 2 and 2, respectively. Since the arrangement of the same is not in alignment due to the design, the diameter does not exactly correspond to the distance between the printing units. The distance can be increased by increasing the diameter.
  • a threaded pin 27 is rotatably provided, which axially shifts the drive spur gear 9 on a spline-shaft connection known per se and disengages from the main spur gear 10 of the main drive (dash-dotted position).
