Definitions

  • the invention relates to a drive of a rotating body according to the preamble of claim 1 or 2.
  • EP 07 22 831 B1 discloses a drive for a cylinder, the cylinder driven by a motor being arranged to be axially displaceable for adjusting the side register.
  • a rotor arranged coaxially on the journal of the cylinder is axially movable in the stator.
  • EP 10 00 737 A1 discloses driving a cylinder sleeve via a shaft which can be axially clamped against a disk. Between the drive motor and sleeve there is an axial coupling which enables the axial relative movement.
  • WO 98/51497 A2 discloses a drive for a rotating component, a journal of the rotating component being connected to the shaft or a rotor of a motor in a rotationally fixed manner via couplings which compensate for two angular deviations.
  • CH 451 968 A discloses a drive of a cylinder via a drive connection with couplings compensating for two angular deviations, designed as cardan joints, and a coupling which absorbs axial movement, designed as a shaft coupling provided with keyways.
  • the invention has for its object to provide a drive for a rotating body.
  • the object is achieved by the features of claim 1 or 2.
  • the advantages that can be achieved with the invention consist in particular in that a drive is provided for pivotable and at the same time axially movable cylinders, with play in the circumferential direction being minimized.
  • the drive connection allows the drive of such movable cylinders by means of any drive motors without the need for a special design.
  • At least one coupling which is flexible in the axial direction is arranged between the drive motor and the forme cylinder. It is in an advantageous embodiment as a torsionally rigid but flexible in the axial direction or compliant shaft coupling, for. B. executed as an expansion or compensating coupling. It is particularly advantageous to use a non-switchable form-locking multi-plate clutch, which, in contrast to other form-fitting clutches, is almost free of play in the circumferential direction without major manufacturing effort.
  • the coupling is form-fitting in the axial direction, but its length is flexible or flexible, e.g. B. performed by elastic and reversible deformation.
  • An embodiment is advantageous in which two couplings compensating for angular deviations and a shaft coupling having at least two flexible or flexible transmission elements in the axial direction are arranged in series between the cylinder and the drive motor.
  • the drive via the coupling is particularly important in the case of individual drives individually driven cylinders, but especially on the forme cylinder to adjust the side register, is an advantage. If the cylinders of a printing group are individually driven by a drive motor, the circumferential register can be changed on the basis of changes in the relative angular position of the drive motor, and the side register can be changed relative to one another by means of the axial displacement. In an advantageous embodiment, the drive motors are arranged coaxially with the cylinder to be driven.
  • the arrangement of the drive motor via the coupling to the forme cylinder of a jointly driven cylinder pair is advantageous.
  • the drive on the forme cylinder means that the drive motor does not have to move when the transfer cylinder is in the up and down position, as is the case, for. T. is the case when driving directly on the transfer cylinder.
  • a compromise based on such pivoting movements of the transfer cylinder in the position of the drive motor and the engagement of the gearwheels when the drive motor is arranged on the transfer cylinder can also be dispensed with when the forme cylinder is driven. In the other case, the latter can lead to tooth breakage or, due to the play in the drive, to a reduction in print quality.
  • a gear in particular a reduction gear, e.g. B. between the drive motor and the cylinder, in particular between the drive motor and the clutch closest to the drive motor to improve.
  • a front-mounted gear unit the drive motor, z. B. a planetary gear in question.
  • the drive motor can be arranged directly axially to the forme cylinder or to the driven cylinder. Embodiments of the invention are shown in the drawings and are described in more detail below.
  • Figure 1 shows a first embodiment for driving a cylinder.
  • Fig. 2 shows a first embodiment for driving a cylinder.
  • a rotating body 01 in particular a cylinder 01 or a roller 01, for. B. a forme cylinder 01, a printing press, in particular a rotary printing press, is on one end face with a shaft 04 rotatably mounted in a side frame 03, z. B. a so-called.

It also has a first coupling half 17, a transmission element 18, for. B. spring washer 18 or disk set 18, a second coupling half 19 and a spherical bearing 21.
  • the second clutch half 19 is torsionally rigid, but in the axial direction relative to a second clutch half 22 of a third clutch 23, e.g. B. another spring washer or multi-plate clutch 23, arranged.
