Definitions

  • the invention relates to a roller drive unit for a machine for producing and / or finishing a paper, cardboard or other fibrous web or for another machine for producing a running web.
  • the invention particularly relates to a drive unit with a roller or a cylinder of a paper machine.
  • This is generally a large cylinder, for example a Yankee cylinder or a creping cylinder.
  • the jacket of a Yankee cylinder or a creping cylinder must be heated to high temperatures of over 100 ° C. This also applies to certain rolls, for example press rolls.
  • a hot medium initiated, for example superheated steam.
  • condensate must be removed from the interior of the cylinder or the roller, in turn through one of the journals.
  • a transmission is pushed onto the trained as a hollow shaft drive pin - so-called slip-on. It is necessary to provide a torque arm, which is anchored on the one hand to the housing of the transmission, and on the other hand to the fixed environment, for example on a foundation part.
  • the invention has for its object to make a roller drive unit of the type mentioned in such a way that any media such as steam or condensate can pass through the hollow drive pin of the cylinder or the roller in a structurally favorable manner that the necessary space is reduced compared to known solutions, and that the total weight of the roller drive unit is reduced.
  • the single motor will be flanged to the gear housing.
  • the entire unit comprising the transmission and the drive motors, is fixedly mounted on or on the frame, for example on a concrete base. It requires thus no torque arm. Also, it requires no drive shafts. It is particularly important that the drive pin is aligned with the axis of rotation of the cylinder.
  • These two - output shaft of the transmission and drive pin of the cylinder - are hollow.
  • the output pin can be provided on its side facing away from the cylinder of the transmission housing with a steam head.
  • the steam head is in a conductive connection with the interior of the cylinder.
  • the drive motors are arranged with their associated pinions symmetrical to the axis of rotation of the cylinder, at least symmetrically to a vertical axis through the axis of rotation of the cylinder.
  • a main bearing is provided in the transmission housing or axially immediately before or behind it, which receives the weight of the engine, transmission and cylinder and initiates directly into the framing of the paper machine.
  • the lubrication of the gearbox takes place by means of the connection to a central oil lubrication.
  • the heat loss of the motors can be dissipated by liquid cooling with water or oil.
  • the liquid temperature is best operated above the required condensation temperature, for example in a range of 50 to 80 ° C.
  • roller drive unit Several motors of a roller drive unit are operated together or separately with one or more frequency converters. Through the use of liquid-cooled motors and optimized peripheral speeds of the pinion shafts, the operating noise of the roller drive unit can be minimized.
  • the direct installation of the individual motor to the gearbox can minimize the necessary space.
  • the assembly work on the construction site is reduced.
  • the roller drive unit can be mounted in its entirety on the chair.
  • the mechatronic roller drive unit according to the invention can be used with any type of rollers or cylinders of a paper machine.
  • the invention is particularly suitable for large cylinders, such as smoothing or creping cylinders.
  • the in FIG. 1 item shown comprises a roller or cylinder drive unit 1.
  • This has a transmission 2.
  • the gear 2 includes a housing 3. This includes, inter alia, a central gear 4 and an output shaft 5.
  • the central gear 4 is on the output shaft 5 form or frictionally and thus rotatably with this.
  • a hollow large cylinder 10, in particular a crepe or Yankee cylinder, has a drive pin 11.
  • Drive pin 11 is rotatably connected to the output shaft 5 of the transmission or designed with this preferably in one piece.
  • the large cylinder 10 facing away from the end of the output shaft 5 carries a steam head 12 with a supply line 13 for supplying superheated steam, and a discharge line 14 for discharging condensate.
  • the housing is mounted on a support 15 and two supports 16, 17, of which in FIG. 1 only the support 16 can be seen.
  • FIG. 1 This is dimensioned such that it carries both the weight of all rotating components of the roller drive unit 1, and also the weight of the steam head 12 and the lines 13, 14, but also the corresponding part of the large cylinder 10.
  • the roller drive unit 1 is located on the drive side of the dryer section or another lot of the relevant paper machine. But it is also possible to arrange the roller drive unit on the leader side of the paper machine. It is understood that on the opposite side, the driver's side, also a bearing for the bearing pin located there of the large cylinder 10 is provided - not shown here.
  • each drive motor is in turn assigned a pinion, analogous to the two pinions 6, 7 of the first embodiment according to the Figures 1 and 2 , Otherwise, the second embodiment is the same as the first one.
  • FIG. 4 illustrates a third embodiment with three drive motors 23, 24, 25. For the sake of simplicity, only the configuration of the drive motors is shown. All other components are those of the embodiment according to the Figures 1 and 2 the same or substantially the same.
  • FIG. 5 schematically illustrates an embodiment in which the drive shaft of the individual drive motors is perpendicular to the axis of rotation of the large cylinder.
  • the illustration is very schematic, but it is sufficient to illustrate this embodiment of the invention.
  • the transmission has an angle drive in this case.
  • This comprises a central bevel gear 40 - in contrast to spur gears according to the previous embodiments.
  • Each drive motor 42 (shown here only a single) drives a pinion 41, which is also designed as a bevel gear and meshes with the central bevel gear 40.
  • the drive motor 42 has an axis of rotation 43 which is perpendicular to the axis of rotation 27 of the cylinder.
  • the motor 42 does not protrude beyond the housing of the transmission (not shown here) - on the side facing away from the cylinder.
  • FIG. 6 illustrates the state of the art.
  • a motor 30 rests on a concrete foundation 31. From the motor 30 torque is introduced via a propeller shaft 32 in a transmission 33.
  • the gear 33 is mounted on a hollow drive pin 34 of a large cylinder 35. Before the gear 33 is a steam head 36.
  • the drive pin 34 is mounted in a bearing 37. Bearing 37 is in turn supported on a stiffener 38.
  • the housing of the transmission 33 is fixed to the frame 38 via a torque support 39.
