Definitions

  • the invention relates to a cylinder drive for a rotary printing press
  • a generic cylinder drive of a rotary printing press is known.
  • a cylinder that can be swiveled in a side frame by means of an eccentric bushing is driven directly by an electric motor.
  • a rotor of the electric motor is firmly connected to a pin of the cylinder.
  • a stator of the electric motor is firmly connected to the side frame by means of a tracking device.
  • the disadvantage here is that a complex device for tracking the stator is necessary.
  • the stator and rotor of the electric motor are not directly rotatably supported relative to each other, so that a constant air gap between the rotor and stator is not guaranteed.
  • Such inaccuracies can occur in particular due to manufacturing inaccuracies, assembly errors or the device for tracking itself. This can cause undesirable vibrations, which can lead to duplication in the printed image, for example.
  • DE 44 22 097 A1 describes an arrangement of an electric motor for driving a printing cylinder of a rotary printing press, which is rotatably supported in an adjustable eccentric bushing.
  • a rotor of the electric motor is rigidly connected to the cylinder.
  • DE 44 30 693 A1 shows an offset rotary printing press with a printing unit with a cylinder mounted in an eccentric bushing. This cylinder is driven directly by means of an electric motor, a stator of the electric motor being rigidly attached to a pin of the cylinder.
  • DE 34 32 572 A1 discloses a cylinder drive in which a rotor of an electric motor is connected to a journal of the cylinder by means of a quick coupling. This quick coupling rigidly connects the journal and rotor.
  • CH 452 288 shows a drive of a plate cylinder which can be pivoted in an eccentric bushing, a drive being effected via a drive wheel of a transmission and a coupling part which enables angular mobility between a pin of the cylinder and the drive wheel.
  • the invention has for its object to provide a cylinder drive of a rotary printing press.
  • a flange motor is used, the flange of which is fastened directly on the end face to an eccentric bushing receiving the cylinder.
  • No complex tracking devices are required for this. Manufacturing and assembly costs as well as inaccuracies are minimized. If the cylinder and the electric motor are connected by means of a clutch, this can, for example, compensate for errors such as axis misalignment, inclined axes or angular errors, so that such errors have no influence on, for example, the service life or running properties of the electric motor.
  • the cylinder drive according to the invention is shown in the drawing and is described in more detail below.
  • a pin 1 of a cylinder 2 of a rotary printing press designed as a forme, rubber or impression cylinder is mounted in a side frame 3, for example by means of a roller bearing 4, so that it can rotate about its axis of rotation 6.
  • This roller bearing 4 is arranged in an eccentric bushing 7, which in turn is pivotally mounted in the side frame 3 by means of a roller bearing 8.
  • a second end of the working cylinder 9 is connected to the side frame 3 by means of a second joint. Fine adjustment devices can be arranged to cooperate with the working cylinder 9.
  • the eccentric bush 7 is secured against rotation and adjustably connected and a position of the axis of rotation 6 of the cylinder 2 can be changed in a plane spanned by the side frame 3 by means of the eccentric bush 7.
  • a position-controlled electric motor 11 is arranged to cooperate with the cylinder 2.
  • the pin 1 of the cylinder 2 is connected to a rotor shaft 13 of a rotor 14 of the electric motor 11 in a torsionally rigid manner by means of a coupling 12.
  • the coupling 11 can, as in the example shown, as a simple flange coupling or, for example, also as an articulated compensating coupling such as. B. Double cardan joint, curved tooth coupling.
  • the rotor 14 or the rotor shaft 13 is mounted in a flange 16 and a cover 17 of a housing 19 containing a stator 18, for example by means of slide bearings.
  • the flange 16 is connected on the end face to the eccentric bushing 7.
  • the electric motor 11, ie its stator 18, is therefore preferably exclusively attached to the eccentric bushing 7.
  • rolling bearings can also be used.
  • a hollow shaft motor can also be used, which can be pushed directly onto the journal 1.
  • the pin 1 is secured against rotation to the rotor of the hollow shaft motor by means of a feather key, splined shaft or serration.
  • a transmission can also be interposed between the electric motor 11 and the pin 1, which is also arranged exclusively on the eccentric bushing 7.
  • This gear is designed as a planetary gear and arranged coaxially to the pin 1.
  • the operation of the cylinder 1 according to the invention is as follows: If the working cylinder 9 is actuated for pressure adjustment, for example, it exerts a force in the circumferential direction on the eccentric bushing 7. As a result, the eccentric bushing 7 is pivoted in the circumferential direction until, for example, a stop (not shown) is reached. This changes the position of the axis of rotation 6 of the cylinder 2 relative to the side frame 3 and thus, for example, to a second cylinder. A position of both the rotor 14 and the stator 18 is also changed at the same time. However, there is no relative movement between rotor 14 and stator 18, so that an air gap between rotor 14 and stator 18 remains constant.
