Definitions
- the invention relates to a cylinder drive for a rotary printing press according to the preamble of claim 1.
- a generic cylinder drive of a rotary printing press is known.
- a cylinder that can be swiveled by means of an eccentric bushing in a side frame 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 one another, 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 a Electric motor for driving a Druckzyl nders a rotary printing press, which is rotatably mounted in an adjustable eccentric bush. A rotor of the electric motor is rigidly connected to the cylinder.
- DE 34 32 572 A1 discloses a cylinder drive, in which a rotor of an electric motor by means of a
- the invention has for its object to provide a cylinder drive of a rotary printing press.
- a flange motor for example, is used in the cylinder drive according to the invention Flange is directly attached to an eccentric bushing receiving the cylinder. No complex tracking devices are necessary for this. Manufacturing and assembly costs as well as inaccuracies are minimized.
- the cylinder drive according to the invention is shown in the drawing and is described in more detail below.
- a rotating component preferably a pin 1 of a cylinder 2 (z. B. Form-, rubber or Druckz linder) of a rotary printing press is rotatably mounted in a side frame 3, for example by means of a roller bearing 4 about its axis of rotation 6.
- This roller bearing 4 is arranged in an eccentric bushing 7, which in turn can be pivoted in the side frame 3 by means of a roller bearing 8 is stored.
- At this eccentric bush 7 engages a first end of an actuator, for example se a controllable working cylinder 9 by means of a first joint.
- a second end of the working cylinder 9 is connected by means of a second joint to the side leg L l 3.
- a position-controlled electric motor 11 is preferably arranged to cooperate with the cylinder 2.
- the pin 1 of the cylinder 2 is connected by means of a coupling 12 to a rotor shaft 13 of a rotor 14 of the electric motor 11 in a torsionally rigid manner.
- the coupling 11 can, as in the example shown, as a simple flange coupling or, for example, also as an articulated compensation such as. B.
- 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 attached exclusively to the eccentric bushing 7. Instead of plain bearings, rolling bearings can also be used. In the event that the stator 18 is firmly connected to the pin 1, the internal mounting of the electric motor 11 can also be omitted entirely.
- 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 key, i e l ke Iwe l le or serration.
- a transmission can also be interposed, which is also arranged exclusively on the Exzenterbuc se 7. This gear is preferably as
- P l ane t enradget ri ebe formed 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 example, for pressure adjustment, 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 low-pressure stop is reached. As a result, 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 is changed. A position of both the rotor 14 and the stator 18 is also changed at the same time. But there is no re lati movement between rotor 14 and stator 18 so that an air gap between rotor 14 and stator 18 remains constant.
