Definitions

  • the present invention relates to a device according to the preamble of claim 1.
  • a device of this type is known from US-A-2 503 858.
  • the roller pressure can be adjusted by means of a preloaded pair of springs, which also acts as a safeguard against overloading the rollers. This device is sufficient if high roller pressures are not required for processing the material web and if a constant roller pressure does not have to be guaranteed.
  • the distance between the cylinders must be observed very precisely and must not change even under load.
  • the cylinders must be able to be started and stopped reproducibly in a simple manner when the web is drawn in.
  • a bearer ring is known from DE-A 31 31 167, the diameter of which can be changed.
  • its treads are formed by interchangeable steel strips which are detachably clamped on an inner ring.
  • the use of such bearer rings has the disadvantage that a change in the center distance of the work rolls can only be carried out when the machine is at a standstill, and it is also labor-intensive to replace the steel belts.
  • a large number of steel strips must be kept in stock in order to be able to adjust the roller spacing as infinitely as possible.
  • the object of the present invention is to improve a device of the type mentioned at the outset in such a way that it ensures a constant roller spacing under high and changing loads.
  • the device shown in the drawing has two working cylinders 1 and 2. Both are rotatably supported in the side cheeks 3, 4 of the machine stand by means of axle journals. On the sections 5, 6 of the axle journals of the upper working cylinder 1, a bearer ring 7 or 8 is fitted, the running surfaces L of which are designed as truncated cone surfaces. 1 converge to the left against the axis of rotation of the working cylinder 1. They are parallel to each other, that is, the two cones forming the lateral surfaces have the same opening angle and are aligned axially with the axis of rotation of the working cylinder 1.
  • the lower working cylinder 2 is rotatably mounted with its axle journals and axially displaceable to a limited extent in bearings 13 and 14.
  • bearer rings 11 and 12 cooperating with the bearer rings 7, 8 are mounted, the running surfaces L of which are also designed as truncated cone surfaces and are parallel to one another. They converge in Fig. 1 right against the axis of rotation of the working cylinder 2, on which the associated cone apex lies.
  • the opening angles of all the circular cones forming the running surfaces L are the same.
  • the two bearings 13 and 14 each have a cylindrical bearing bush 15 which is rotatably mounted in a corresponding bore 16 in the side cheeks 3 and 4, respectively.
  • the axle journals are mounted eccentrically to the center axis of the bearing bush 15, so that the axis spacing between the bearer rings 7, 8, 11, 12 changes when the bearing bushes 15 rotate.
  • a toothed segment 17 is attached to each bearing bush 15.
  • a tooth segment 18 meshes with each of these, which are non-rotatably mounted on a shaft 19.
  • the shaft 19 can be driven manually or by a motor on both sides by means not shown.
  • a bracket 20 is fixedly connected to the cheek 3, in the yoke of which an adjusting screw 21 is rotatably mounted. This is screwed with its threaded shaft end into a threaded bore 22 of the left journal of the work roll 2.
  • the threaded bore 22 is aligned axially to the axis of rotation of the work roll 2. If the screw 21 is rotated, the work roll 2 shifts axially in its bearings 13 and 14.
  • the conical running surfaces L of the bearer rings 7, 8, 11, 12 shift in the direction of the axes of rotation relative to one another, thereby increasing their center distance in accordance with the direction of displacement or reduced.
  • the shaft 19 is preferably rotated before or during the turning of the screw 21 and the contact pressure of the work rolls 1, 2 is reduced.
  • the width of the gear wheels 23, 24 which connect the work rolls 23, 24 in terms of gear are designed so that they remain in full engagement over the entire axial displacement range of the work roll 2.
  • the work rolls 1, 2 are preferably punching or printing rolls; however, they can also serve other processing purposes.
