Definitions

  • the invention relates to a device for eliminating tooth play of two directly interacting gear wheels, in particular cylinders of a rotary printing press, according to the preamble of claim 1.
  • DE 28 15 534 C2 discloses a generic device for eliminating tooth play in a gear transmission, in particular on printing cylinders and transfer drums of printing machines.
  • a first gearwheel is provided with a toothed segment and interacts with a second gearwheel.
  • the toothed segment By adjusting the toothed segment with respect to the first gearwheel in the circumferential direction, the tooth play between the first and second gearwheels is eliminated.
  • a disadvantage of this device is that this device cannot be adjusted during the rotary movement of the cylinders.
  • the invention has for its object to provide a device for eliminating backlash of two directly interacting gears, in particular cylinders of a rotary printing press, the cylinders having variable center distances, and thus changed backlash caused by the Device can be compensated for during the rotary movement of the cylinder.
  • the device according to the invention can also be applied to cylinders with a variable center distance. So it is z. B. in gravure printing machines or offset printing machines necessary to adjust the distance between the form and impression cylinder or rubber and impression cylinder of the thickness or the surface quality of the printing material. This increases the backlash between the corresponding gear wheels of the cylinders, which can lead to vibrations or decrease, which can cause the teeth to jam and damage. In order to avoid these disadvantages, it is necessary to adapt the tooth play to the respective center distance of the cylinders. It is particularly advantageous that the device according to the invention enables the tooth play to be adjusted during operation of the printing press. This means that set-up times can be shortened and expensive production interruptions are not necessary.
  • the device according to the invention positively reduces the backlash by adjusting the toothed segment in the circumferential direction and thus does not generate any additional forces on the gearwheels.
  • a sheet-fed rotogravure printing machine is, in a known manner, a first cylinder 2, z. B. a forme cylinder 2, a second cylinder 3, z. B. a pressure cylinder 3 and a third cylinder 4, z. B. a transfer drum 4 stored.
  • the forme cylinder 2 interacts with the impression cylinder 3 and these two cylinders 2, 3 have an axial distance a23, this axial distance a23 being variable, ie adaptable to different operating states.
  • the transfer drum 4 works with Printing cylinder 3 together.
  • These cylinders 2, 3, 4 are provided with pins 6, 7, 8 and on each pin 6, 7, 8 a gear 9, 11, 12 is attached in a torsionally rigid manner.
  • gear wheels 9, 11, 12 transmit a torque required to drive the cylinders 2, 3, 4.
  • a second gear 13 is rotatably supported independently of the pin 6.
  • This gearwheel 13 has a width b13 and likewise interacts with the gearwheel 11 of the printing cylinder 3, a width b11 of the gearwheel 11 of the printing cylinder 3 being approximately the sum of a width b9 of the first gearwheel 9 and a width b13 of the second gearwheel 13 corresponds to the forme cylinder 2.
  • phase adjustment gear 14 is designed as a traction mechanism gear, in particular as a toothed belt gear. It essentially consists of a first and a second pulley 16, 17, which interact via a toothed belt 18.
  • the first pulley 16 is torsionally rigid with the second, freely rotatable gear 13 of the forme cylinder 2
  • the second pulley 17 is torsionally rigid with the gear 12 of the transfer drum 4.
  • the gear 12 of the transfer drum 4 and the freely rotatable gear 13 or the fixed gear 9 of the forme cylinder 2 have the same transmission ratio as the pulleys 16, 17 of the Phase adjustment 14 on.
  • the gear ratio is 1 to 1, but any other is also possible.
  • the toothed belt 18 is operated by means of two tensioning rollers 19, 21, each of which acts on a drive strand 22 and one on an empty strand 23 of the toothed belt 18. These tensioning rollers 19, 21 are fastened on a common coupling 24, as a result of which a distance a18 between the idle and drive strands 22, 23 is established. The toothed belt 18 is tensioned by shortening this distance a18.
  • a change in the position with respect to a plane of the coupling 24 spanned by the forme cylinder and transfer drum 4 causes a change in the respective length of the idle or drive strand 22, 23 and thus a change in the bearing angle of the two pulleys 16, 17 to one another, ie a change in the Phase position.
  • the freely rotating gear 13 of the forme cylinder 2 can of course also be designed only as a toothed segment if freedom from backlash is only required at one point or in a region of the circumference.
  • the third gear 12 does not have to serve to drive a cylinder 4, but can of course also have its own cylinder-independent storage. Also, the pulleys 16, 17 of the phasing mechanism 18 do not have to be connected directly to the gears 12, 13 of the cylinders 2, 4, any intermediate wheels and other diameters are possible. What is common here, however, is that the gears 12, 13 of the cylinders 2, 4 and possibly gears of the adjusting gear 18 in the contact points 26, 27 of the forme and impression cylinders 2, 3 produce the same circumferential speeds.
  • the coupling 24 is rigid after the adjusting movement, not sprung, for. B. by means of a threaded spindle, arranged. The tooth play is thus eliminated in a form-fitting manner.
