Definitions

  • the invention relates to a rotatably mounted roller, comprising a roll shell, as well as two lids, which together with the roll shell enclose an interior, further bearing journals, which are supported by a stand.
  • a roller is associated with a drive which comprises an electric motor and which transmits torque to one of the bearing journals.
  • a drive which comprises an electric motor and which transmits torque to one of the bearing journals.
  • the electric motor and the bearing pin further drive elements may be provided, for example, a coupling and a propeller shaft.
  • Rolls of this type are used, inter alia, in paper making, for example in paper machines or in slitter rewinding machines.
  • DE 10 2005 011 431 A1 describes a roll having a roll shell and a roll axis and an electric motor which drives the roll.
  • the rotor of the electric motor is rigidly coupled to the axis of the roller, and the stator of the electric motor mounted on the axis of the roller.
  • Such a design is, as stated in the document, at best suitable for regulating rolls, spreader rolls or guide rolls, but not for large heavy rolls such as drying cylinders of paper machines.
  • the invention has for its object to provide a roller with associated drive, in which the axial length is minimized, and in which the torque transmission from the motor to the roller is made without further mechanical drive units.
  • the solution should also be suitable for large, heavy rolls of large diameter and long length.
  • an electric motor is provided as the drive, which is arranged in the interior of the roller.
  • the rotor of the motor is in drive connection with the roll shell or with one of the two lids located at the ends of the roll.
  • the stator has at one axial end on a support pin, which is passed through the respective journal of the roller.
  • the electric motor is arranged in the vicinity of a roller cover, thus directly at the respective end of the roll mantle. He can be stored on the fly. There is no need for a rigid axle that extends through the roller over its entire length. The axial space requirement is minimized by requiring the drive motor to have virtually no axial space beyond the roller. Any mechanical torque transmission units such as cardan shafts, clutches are dispensable. It reverberations are avoided, as generated for example by angular changes of propeller shafts. The dynamic control properties are favorable.
  • the drive-side part of a roller 1 is shown.
  • the roller is part of a paper machine. It could also be used for a calender or slitter.
  • an electric motor comprising a rotor 7 and a stator. 8
  • the rotor 7 is also associated with a housing, namely rotor housing 12. Rotor 7 is rotatably connected to a rotor shaft 13. The rotor shaft 13 is mounted in the stator housing 9 - see the bearings 14 and 15.
  • Flange 16 is fixedly connected to the rotor shaft 13, for example by means of a spline connection or by means of a shrink connection. Flange 16 is bolted to the rotor housing 12.
  • the rotor housing 12 is rotatably connected to the rotating components of the roller 1, in the present case with the cover 3 of the roller first
  • the support pin 10 of the stator housing 9 has openings 17. These are used to pass through connecting lines 18, 19. These may be lines for passing electrical energy, electrical signals or cooling water.
  • the rotor housing 12 runs during operation of the roller 1 together with the remaining, rotating parts of the roller 1. If required for static reasons, a support for the rotor housing 12 could still be provided against the inner surface of the roll shell 2, for example, at that end of the rotor housing 12, which is opposite to the lid 3. But this is not shown here.
  • a part of a roll 1 can again be seen, with a roll shell 2, a cover 3, a bearing journal 4 and a frame 5 with bearing 6.
  • stator 8 is enclosed by the rotor 7. Rotor 7 is thus located radially outside of the stator 8.
  • the stator 8 has a support pin 10. This is passed through the bearing pin 4 of the roller 1 and is supported on the fixed environment - see the torque arm 11th
  • a rotationally symmetrical support can be provided to a fixed environment, which, however, is not shown.
  • a rotor housing 12 is provided. This carries the rotor 7 and is connected to this of course rotatably. It is also rotatably connected to the roller 1, with the cover 3 recognizable here.
  • the rotor housing 12 is supported on the one hand on the support pin 10 of the stator 8, on the other on a further support pin 20 of the stator 8.
  • Trunnion 20 is the lid-facing trunnions 10 axially opposite. See the two bearings 21, 22.
  • trunnion 10 which is passed through the rotor housing 12 and through the bearing pin 4, designed as a sleeve. Through this hollow trunnion 10 can be lead through leads, such as cables, cooling water lines, power lines, signal lines and so on.
  • the support pin 10 of the stator 8 is supported on the fixed environment.
  • the cover-side support pin 10 could also be mounted on the bearing pin 4.
