Definitions

  • the invention relates to a drive unit according to the preamble of claim 1.
  • Such a drive unit is known from DE-A-195 21 205, which relates to the pair of rollers of a roller press.
  • the Torque arm allows a change in the radial distance between the two rollers too.
  • EP-A-0 280 897 which a roll mill for Shredding of brittle goods such as cement clinker relates, or from DE 40 19 363 C1, which a roller drive for presses, or from DE-A-198 22 341, which relates to a drive device for two common rollers.
  • rollers arranged parallel to one another for guiding goods known, for example from printing companies or from the Paper industry as well as from the areas of wallpaper production, from weaving mills and in general from the textile industry, at where the material between the rollers is not processed.
  • “leading” in contrast to “editing” means that two adjacent rollers are spaced apart are and the good not through the simultaneous action of both Rolls is treated, so not for example printed, embossed or is crushed, and that it is only one of these at a time two adjacent rollers.
  • the first drained paper web by one A large number of rollers are meandering, these rollers are heated to dry the paper web. Because of the distance of the adjacent rolls are not a combination made of fixed and floating bearing rollers, but both as fixed bearing rollers. In these cases, neighboring ones Often roll the same direction of rotation.
  • Roller systems for guiding the goods can have lengths of 60 up to 70 m, with foundation subsidence over this length are often unavoidable, so because of this or other influences on a roller over the course of its service life if necessary, move by several 1/10 mm, for example lower can.
  • the torque arm as a rigid support for the Gearbox or as a rigid connection between the transmits two gear housings of two adjacent rollers then such high forces on the gear housing that the load on individual gears of the gearbox concerned increases significantly and premature wear at least the Transmission can be the result.
  • the invention has for its object a generic To improve the drive unit in such a way that this is more reliable Torque support for the longest possible service life the gearbox enables.
  • the invention proposes not only that Parallel displacement of the roller transversely to its longitudinal axis enable, but also a rolling movement in the direction from the roll longitudinal axis as well as tilting movements of the roll.
  • the flexibility must be provided for in the design in the longitudinal axis of the roll and a tilting movement the roller is not designed for normal operation, but enables movements to be balanced, for example in the foundation, which occur unscheduled and for example only a few years after the commissioning of the Rolls occur. Due to the free mobility according to the invention the rollers will therefore overstress the Gearbox avoided, so that its particularly long life can be ensured. Unplanned and unwanted Mobility of the roller due to, for example, lowering of the foundation otherwise can lead to tension lead between roller and gear unit, leading to premature Wear and a shortened service life of the gear unit being able to lead.
  • a tongue and groove connection between the Gearbox and the torque arm enables one problem-free longitudinal movement between gearbox and Torque support, this mobility through the screw is favored between the components in which the screws are guided in elongated holes.
  • the order a tongue and groove connection in the transition area between Torque support and gear housing enables a kinking or bending movement of the gear housing opposite the torque arm, so that the gearbox always connected to the roller in its intended arrangement can remain and possible longitudinal displacements of the roller or tilting movements of the roller by a corresponding one Kinking movement between the torque arm and the gearbox can be compensated.
  • the tongue and groove connection can be created be that both in the gearbox and in the Torque support each a groove is provided, the assigned tongue extends in both grooves. To this Way, a reliable bond between the torque arm and reached the gear housing and at the same time easy movement in the longitudinal direction of the grooves between these two components.
  • the depth of the total can be advantageous in the tongue and groove connection trained groove be greater than the strength or depth the spring, so that when the spring is arranged in the groove, a Free space remains in the groove.
  • the manufacturing costs for a tongue and groove connection can in this way because of the more generous Tolerances are kept low.
  • a profile can advantageously be provided in the groove, which acts as a kind of "adapter” and in turn forms a groove, in which the spring is then taken up.
  • the tongue and groove connection can be on this Connect quickly and with little cost be replaced without the entire torque arm or exchanged the assigned gear housing should be.
  • the articulation between gearbox and Torque support can advantageously be ensured by that when screwing the screws over a certain Section of their length from a spring or a similar compressible material are surrounded, this resilient Spacer is only partially compressed and so that there is a certain preload for the screw connection.
  • the addition to the compression of the spacer available way allows under additional compression of the spacer the torque arm compared to Lift off gearbox and consequently bend it or bend so that the desired mobility between Roller and gear housing on the one hand and the torque arm on the other hand, wear-free and gentle on the material Type is given.
  • due to the spring elasticity ensured that when the roller and thus the Gearbox in the original position, the torque arm can still work effectively without an inadmissible To have game.
  • the spring elasticity of the connection between the torque arm and gear housing can be supported in that the torque arm for the longitudinal mobility of the axis or designed for their tilting mobility more deformable is than in other directions.
  • the Torque support designed with an elongated cross section be, for example, plate-shaped, and elongated with this Cross-section arranged transversely to the longitudinal axis of the roll, so that the torque arm during longitudinal or tilting movements due to bending or torsion the mobility of the roller not impermissibly restricted.
  • a torque arm according to the invention can not only a single roller, but it can in particular be inexpensively provided, two parallel to each other arranged rollers by such a torque arm connect with each other. Forces occurring are therefore not directly introduced into the machine frame, but first picked up on another roller and effective if necessary Then residual forces or moments in the machine frame initiated.
  • the tongue of the tongue and groove connection can advantageously be slightly crowned be contoured so that it requires little effort and can be moved out of the assigned groove without jamming can and then with just as little resistance back into the Groove can slide back when the Torque angled in relation to the gearbox becomes.
  • Fig. 1 is a paper making device only shown in sections and hints.
  • the Device 1 has a plurality of rollers 2, which in its Inside are steam heated and around the meandering drying paper web is guided.
  • One is purely schematic Drive shaft 3 indicated, which on a front of one Roller 2 arranged gear 4 acts.
  • This gear 4 meshes with adjacent gears 4 of adjacent rollers 2, the gears 4 are each offset so that none from the different directions of rotation of the rollers 2 resulting disabilities occur.
  • rollers 2 are basically identical to the other rollers 2 are formed, which, however, do not have such gear wheels 4 how the other rollers 2 are driven, but by each with its own gear unit 5.
  • the two gear units 5 are interconnected by a torque arm 6.
  • the arrangement of the gear units 5 is clear from FIG. 2 can be seen:
  • the gear units 5 are instead of otherwise used large gears 4 on the axes of the rollers 2 set and allow the drive of the rollers 2 with Speeds that may damage the would lead large gears 4 and the one accordingly higher production output of the entire device 1 enable.
  • Fig. 3 shows a view of the back of a gear unit 5:
  • the gear unit 5 has a gear housing 7 the back of the torque arm 6 with four connecting screws 8 is screwed.
  • the connecting screws 8 are guided through slots 9, which are in the longitudinal direction the torque arm 6 extend.
  • Fig. 5 shows a cross section through such a screw.
  • the connecting screw 8 extends through a sleeve 10 which has a circumferential collar 11 directed towards the screw head and abuts the transmission housing 7 with its opposite end.
  • the length of the sleeve 10 is greater than the thickness of the torque arm 6, so that there is a gap between the surface of the torque arm 6 and the collar 11.
  • several plate springs 12 are arranged, which are supported on the one hand on the collar 11 and on the other hand rest against a washer 14.
  • the plate springs 12 form an overall compression spring against the effect of the torque arm 6 from the gear housing 7 can be lifted off, so that a corresponding Tilting movement of the torque arm 6 relative to the gear housing 7 is possible.
  • This tilting movement is in the plane possible, in which the two axes of the rollers 2 run, so that axial displacements of the two rollers relative to each other without any tension caused by the corresponding Tilt mobility of the torque arm 6 can be absorbed can.
  • FIG. 4 shows the gear housing 7 recognizable with a recess 16, which is about the recess 16 forks the torque arm 6.
  • the grooves 17 in the torque arm 6 immediately serve to accommodate a spring 19, which on several Set is held by retaining screws 20.
  • the depth of the groove 23 is greater than the dimensions require the spring 19 so that a space 24 at the bottom of the Groove 23 is created. This free space 24 supports the possibilities of movement the torque arm 6 compared to that Gear housing 7 and simplifies the manufacture of the torque arm or the tongue and groove connection 15, since their Depth does not require exact dimensional accuracy.
  • the tongue and groove connection 15 allows the movement of the one hand Torque support 6 in its longitudinal direction with respect to the gear housing 7 on the other hand and also secures at opposite the gear housing 7 tilted torque arm 6 a Power transmission from the transmission housing 7 to the torque arm 6th
  • Deviating from the illustrated embodiment can other types may be provided, the torque arm 6 to the Have the gear housing 7 connected.
  • the illustrated embodiment enables the Mobility with minimal structural dimensions, so that compared to the space required for the actual torque arm 6 no additional installation space in the area of the gear units 5 are needed
