Definitions

  • the invention relates to an intermediate gear for transmitting a rotary motion in a reciprocating motion of a part to be driven mounted outside the gear with a variable phase position from drive to output, in particular a roller in inking and / or dampening units of offset printing presses according to the preamble of the first claim.
  • An intermediate gear of the type specified above is known from DE-PS 800 264.
  • the gearbox uses a pair of cardan circles (see FIGS. 3 and 4) with an adjustable ring which has internal teeth.
  • the intermediate gear allows the deflection of a back and forth movement to be changed in a particularly space-saving manner and, at the same time, the phase position to be changed from drive to drive.
  • a planet gear driven by a crank pin is accommodated to save space.
  • the disadvantage is that the reduction ratio of the intermediate gear is fixed at 1: 2.
  • Intermediate gear with variable phase position from drive to output which different gear ratios and exclusively Have rotatably arranged gear members, which can be stored free of play and wear-free, are known per se, for example from DE-OS 2 228 939.
  • This intermediate gear is a gear with a variable phase position for the axial displacement movement of two mutually oscillating friction rollers in inking units .
  • the disadvantage is that the drive part of such an intermediate gear requires a large amount of space, so that it cannot be accommodated on the drive side of an offset printing machine.
  • the intermediate gear according to the invention has significant advantages. First of all, it is particularly space-saving and can therefore be accommodated on the drive side of an offset printing machine. Furthermore, due to the possibility of using only backlash-free, wear-resistant bearings, i.e. by dispensing with the sliding guide on the gearbox output part and the fact that the drive and output directions of rotation remain the same, it is particularly suitable for high-speed machines, with a variable (e.g. integer) reduction of the rotary movement , e.g. 1: 2, 1: 3, 1: 4, 1: 8 can be realized.
  • a variable (e.g. integer) reduction of the rotary movement e.g. 1: 2, 1: 3, 1: 4, 1: 8 can be realized.
  • a pendulum-like reciprocating siphon roller 16 takes fresh printing ink and transfers it to a distribution roller 15.
  • the ink flow leads via an ink supply roller 14 to another distribution roller 12.
  • This distribution roller 12 divides the ink flow in two ink streams, one of which is guided onto a branch roller 11 and the other onto a branch roller 13.
  • the first partial ink flow is passed via the branch roller 13 and an ink transport roller 8 to two front inking rollers 3, 4.
  • the second ink stream is passed via the branch roller 11 and a friction roller 7 to the first application roller 3 and additionally to a further ink application roller 2.
  • the inking rollers 2 to 4 ink an offset printing plate, which is clamped on the plate cylinder 1.
  • the second applicator roller 4 is followed in the direction of rotation of the plate cylinder 1 by a rear inking roller 5 and optionally another inking roller 6.
  • Another inking roller 9 rolls on the inking rollers 4 and 5, and a plastic-coated inking roller 10 is mounted on the inking rollers 5, 6 as a rider roller.
  • the friction rollers 7, 9, 12 are rotated by a central gear 38 arranged between them, which was then driven by the plate cylinder 1.
  • the friction roller 15 is also driven via a further central gear, not shown.
  • a toothed ring 44 is also rotatably arranged via bearings, which is adjustable via a toothing provided on its outer contour and a toothed pinion 45 engaging in it.
  • the toothed pinion 45 is fastened on an adjusting shaft 46 which is rotatably mounted in a holding plate 75 of the machine frame 41, the adjusting shaft being designed to be rotatable from the outside by hand or also by means of a motor in the machine barrel and can be locked in this position.
  • a worm can be used, which cooperates with a worm gear teeth on the ring gear 44 self-locking. It is also conceivable to use a sprocket instead of the pinion 45 to drive the adjusting shaft 46.
  • bores 61 to 63 are located on the ring gear 44 at a distance a around the drive axis 56 of the coaxial shaft journal 39 of the drive shaft 37. These are offset by the same angular amount, e.g. the three bores shown in FIG. 3 are each offset by 120 °.
  • the planet gear 43 is firmly seated on a stepped collar of a disk 48 which is rotatably mounted on the eccentric pin 40 of the drive shaft 37.
  • a plurality of rollers 50 to 52 are located on the disk 48 at the same distance a around the center of the pin 49.
  • the rollers are supported on the inner surface of the bores 61 to 63 and roll on the surface thereof, the axes 53 to 55 of which move on a circular path 58 to 60.
  • the distance between the axes 64 to 66 of each bore 61 to 63 to the axes 53 to 55 of each roller 50 to 52 must be selected equal to the distance e of the drive axis 56 of the drive shaft 37 to the center of the pin 49 of the eccentric pin 40 in order to ensure a perfect transmission quality of the transmission to guarantee.
  • the radius of the bores 61 to 63 is thus calculated from the sum of the eccentricity of the planet gear 43 and the radius of the cam rollers 50 to 52.
  • a sun gear 42 provided with an internal toothing 47 is rotatably mounted as a gear output part, in which the planet gear 43 engages.
  • a sliding block 23 is adjustable and lockable in a groove 22 of the sun gear 42 by a screw 21.
  • a rocker arm 20 is rotatably received via a bearing, the movement of which is transmitted via coupling elements 24 to 29, 31 to 36 in a manner known per se to the stub axles 70 to 72, 76 of the friction rollers 7, 9, 12, 15.
  • the rotation of the planet gear 43 on the eccentric pin 40 is prevented by the rollers 50 to 52.
  • the rollers 50 to 52 are supported in the bores 61 to 63 of the gear 44 and roll evenly on their surface. This means that the center of the planet gear 43, at the same time the center of the pin 49 of the eccentric pin 40, rotates on a circular path 57, the radius of which corresponds to the eccentricity e (crank circle).
  • the axes 53 to 55 of the rollers 50 to 51 also describe a circular path 58 to 60, the radius of which also corresponds to the eccentricity e.
  • the phase position changes from drive to output.
  • the crank drive 18 coupled to the rotating sun gear 42 on the output side or a comparable output generating a reciprocating movement is not influenced with regard to the deflection of the movement.
  • the Phase position and a stroke or the deflection of the reciprocating movement can be set independently of one another. The meaning of such an adjustment possibility is described in DE-OS 2 228 939.
  • the intermediate gear according to the invention with a variable phase position from drive to output can be replaced by replacing the crank mechanism 18 with a known cam mechanism not shown in the drawing, also for converting a rotary movement into the pendulum movement of a lifting roller with a variable phase position, e.g. use in inking units.
  • the cam disc is attached to the sun gear 42 and its movement is transmitted in a known manner to a roller lever (not shown) connected to the roller axis of the lifting roller.
  • Another application would be the control of switching movements of parts, e.g. the gradual switching of a duct roller in inking units.
  • the gimbal-type intermediate gear according to the invention can be used for applications with large ratios in which the working time of a device connected to the intermediate gear is to be adjusted while the machine is running in an extremely space-saving design, without the deflection or stroke of the oscillating movement being adjusted by the adjustment to influence.
