Definitions

  • the invention relates to a press arrangement for treating a fibrous web, in particular a paper or cardboard web, with at least two press rolls to form at least one press nip. It also affects a press roll according to the preamble of claim 10.
  • the aim of the invention is to provide an improved press arrangement at the beginning to create the type mentioned, in which the aforementioned disadvantages are eliminated are.
  • Suitable press roll are created, which are used as a standard press module Universally applicable in as large a number of press concepts as possible is.
  • the period of use of the press roll bearings, especially for counter rolls to shoe presses should be increased and be predictable. In particular, it should also be almost the same, preferably minimal Axial force must be ensured.
  • Such a press roll should in particular also for so-called combination presses and multi-roller shoe presses be applicable.
  • this object is achieved according to the invention solved in that at least one press roll on at least one roll end is supported by a floating bearing, the inside of the bearing housing arranged bearing rings in the direction of the roller axis relative to each other are movable.
  • the two bearing rings of the floating bearing are preferably also tiltable relative to each other.
  • the press roll in question can thus expand as desired without a sliding outer ring or other guides Load for length compensation would be required.
  • the press roll in question can be used as a press component in a wide variety of press concepts be used.
  • the floating bearing function is within the bearing housing Fulfills. For example, it can also be used for so-called combi presses conceivable. An inclined installation is easy possible. There are new suspension points for the entire press module possible.
  • the respective bearing housing can be directly fixed and be compactly connected to the chair. Overall, there is one less expensive construction.
  • the maximum tilt angle can be, for example, about 0.5 °.
  • Press arrangement are the two bearing rings arranged between them Bearing elements supported on all sides.
  • bearing elements can in particular, bearing rollers can be provided.
  • a corresponding one is advantageously at least on the driver's side Non-locating bearing provided.
  • the press arrangement can comprise at least one shoe press, wherein in this case advantageously at least one of each Mating roller assigned to the shoe press roller on at least one roller end is stored by a floating bearing.
  • the press roll bearings can be made with positive connection elements be connected to the bearing housing of press rolls, which a shift allow by changing the length in the rollers. It follows especially a crossbar elasticity.
  • the press roll according to the invention is characterized in that it at least one roller end is provided with a floating bearing, the inside of which of the bearing housing arranged bearing rings in the direction of the roller axis are displaceable relative to each other.
  • FIG. 1 shows a purely schematic representation of an exemplary embodiment a press assembly 10 for treating a fibrous web 12, which is in particular a paper or cardboard web can act.
  • the press assembly includes four press rolls 14, 16, 18 and 20 through the three successive press nips S1, S2 and S3 are formed, through which the fibrous web 12 is passed.
  • the first formed between the first two press rolls 14 and 16 Press gap S1 is felted twice.
  • the fibrous web 12 is between a bottom felt 22 and a top felt 24 passed through the press nip S1.
  • the second formed between the two central press rolls 16 and 18 Press gap S1 is simply felted.
  • the fibrous web 12 becomes together with the upper felt 24 through this press nip S2.
  • the upper Press roll 20 is formed by a shoe press roll, which is the central one Press roll 18 is assigned as a counter roll.
  • the one through this shoe press 18, 20 formed third press nip S3 is simply felted.
  • the counter roll 18 assigned to the shoe press roll 20 is preferably at the end of the roller provided on the driver's side by a 4 schematically shown floating bearing 26, its inside of the bearing housing 28 arranged bearing rings 30, 32 in the direction of Roller axis X are displaceable relative to each other.
  • the two bearing rings 30, 32 of the floating bearing 26 can also be tilted relative to one another.
  • the maximum Tilt angle for example, be about 0.5 °. 4 is the Angle deflection indicated greatly enlarged.
  • the inner bearing ring 30 is attached to the relevant end of the counter roller 18. For example, it can be attached to a bearing or shaft journal 34 of this counter-roller 18.
  • the outer bearing ring 32 is on the bearing housing 28 attached.
  • the two bearing rings 30, 32 are through between arranged bearing elements 36 supported on all sides. As storage elements In the present case, 36 bearing rollers are provided.
  • the bearing housing 28 can be fixed to the frame of the paper machine in question be connected.
  • FIG. 2 shows a further possible embodiment in a purely schematic representation a press assembly in which one in the previously described Way with a floating bearing press roller can be used.
  • This press arrangement shown in FIG. 2 comprises only three Press rolls 16, 18, 20, through which two press nips S1 and S2 are formed.
  • the first press roll 16 is in the present case as a press suction roll executed.
  • the upper press roll 20 is again designed as a shoe press roll, which the central roller 18 is assigned as a counter roller.
  • the two Press gaps S1 and S2 are each simply felted, the fibrous web together with an upper felt 24 through the first press nip S1 and together with an upper felt 25 through the second press nip S2 is led.
  • the counter roll 18 assigned to the shoe press roll 20 is in the same Way as the counter roller 18 of the press assembly 10 according to FIG. 1st preferably on the driver's side again through a floating bearing 26 in particular of the type shown in FIG. 4.
  • the relevant press rolls 18 can thus in particular at least on one side be stored by a so-called CARB bearing, the inside of the bearing housing 28 arranged bearing rings 30, 32 in the direction of Roller axis X displaceable relative to one another and moreover preferably are tiltable relative to each other (see. Fig. 4).
  • Figure 3 shows a schematic representation of a press section with three Press rolls, two press rolls 20, 20 'on the central press roll 18th are arranged.
  • the bearings of the press rolls 20, 20 'with positive connection elements 38 to the bearing housing of the press roll 18 are connected, which is a shift due to change in length allow in the rollers 20, 20 '.
  • Figure 5 shows a more detailed schematic representation of an embodiment a press arrangement with three press rolls 16, 18 and 20, based on the following some advantages of the used for the press rolls Floating bearings or CARB bearings can be shown.
  • the through the axes of the two press rolls 18, 20 connecting line is denoted by "Y".
