Definitions

  • the invention relates to a rolling mill with two rolls forming a nip, the over Drive spindles are driven by their own drive motors, in particular quarto-framework, wherein for each roller in each case a drive train, each with a toothed coupling combined with another joint coupling is used.
  • the arrangement requires two drive motors - a so-called Twin drive - due to the large center distance of the motor drive shafts large diffraction angles of the drive spindles or, if one wants to avoid such correspondingly long drive spindles, but this would give a rotary soft drive.
  • a rolling mill is known in which the rollers each have a first toothed coupling with a first shaft and a second toothed coupling with a Connecting shaft and continue via a universal joint with a propeller shaft and another Universal joint is connected to a drive motor or another propeller shaft.
  • the Connecting shafts are in an adjustable guide in parallel arrangement stored. As a result, must be taken by the gear couplings relatively large angle be, because there must be a sufficiently large distance between the at the Connecting shafts arranged universal joints are created. This increases significantly the wear of the toothed couplings.
  • Another disadvantage of the known rolling mill is to see that the distance between the engine and roll stand is very large, which is a space consuming drive arrangement results. This also results in too soft Torque transmission from the drive motors to the work rolls.
  • the invention aims to avoid these disadvantages and difficulties and arises the task of creating a rolling stand, which also applies to rolls with small diameters and on the other hand a relatively large center distance of the motor drive shafts Drive spindles can be provided with a large diffraction angle - and so that with a relatively short length - can be arranged, but still very much high drive torques can be transmitted, for example, for rolling high-strength Rolled and rolled with large Stichief discretion.
  • This construction is particularly space-saving and enables optimal moments Dimensioning even with very narrow center distances of the rollers.
  • the toothed couplings crowned collaboratever leopardept on wherein to achieve a axial mobility of the driven rollers themselves the internal teeth of the toothed couplings in the axial direction over a multiple of the external toothing extend.
  • the optimal pressure angle of the Gear coupling i. the optimal angle between the Axle of the roller and its associated toothed spindle especially when changing the roll gap, is the part movable relative to a roller the toothed coupling of the toothed spindle, with the cardan shaft is connected via a balancing device to comply with a predetermined angular position on Foundation supported, with the compensation device from a trained as a lever system parallel guide is formed.
  • Fig. 1 is a Schrägrißansicht and Fig. 2 a through the axes of the drive spindles laid vertical section of a detail of FIG. 1 of an embodiment.
  • the only a relatively small diameter 10 having work rolls 1, 2 are each over a own drive spindle 11, 12 by means of its own Drive motor 13, 14 drivable.
  • the arrangement of Drive motors 13, 14 is made such that the Center distance 15 of the drive shafts 16 of the drive motors 13, 14 is as low as possible.
  • the drive spindles 11, 12 to each other arranged inclined.
  • each drive pin 4, 5 the work rolls 1, 2 rotatably connected to a sleeve 17, which has an internal toothing 18.
  • Internal toothing 18 engages a convex outer toothing 19, the outside of another sleeve 20 is arranged, a.
  • the sleeves 17 and 20 thus form one toothed coupling each.
  • the length of the internal toothing 18 is many times longer than the teeth of the External teeth 19, so that an axial mobility is possible.
  • the work rolls 1, 2 in Axial direction relative to the roll stand 7 shifted become. Different axial layers of the work rolls 1, 2 are shown in Fig. 2.
  • Sleeves 20 are each rotationally fixed to a spindle 21 and 22 mounted and form together with this spindle 21st or 22 a so-called toothed spindle.
  • the universal joints 24 could also be provided other articulated couplings to be high in transmission Torques are suitable, for example, flat-pin couplings.
  • the drive spindle 11 of the lower work roll 1 is up to the drive shaft 16 of the lower Drive motor 13 rigid formed and with the drive shaft 16th of the lower drive motor 13 via a toothed coupling 24 'coupled.
  • the axial positions of the toothed spindles 20, 21 and 20, 22 are chosen so that their axes with the axes of the associated work rolls 1, 2 a Angle between 0.5 and 1.5 °, preferably an angle of about 0.8 °.
  • the parallel guide 25 is of a toggle lever system formed, u.zw. grab something vertically oriented Tabs 27 on one the upper toothed spindle 20, 22nd surrounding and opposite the toothed spindle 20, 22nd by means of rotary bearing 28 supported housing 29, which Housing 29 against rotation against the foundation 26 is.
  • the tabs 27 are each at one Angle lever 30 articulated, the knee joint 31 on Foundation 26 is rotatably supported.
  • the others Lever arms 32 of the angle lever 30 are connected via a pull or pressure-absorbing tab 33 connected.
  • the arrangement of the toothed spindles 20, 21 and 20, 22 is in this case made so that these in the direction of the drive motors 13, 14 diverge, causing it succeeds that the propeller shaft 23 with the toothed spindle 20, 22 connecting universal joint 24 with maximum size to design.
  • This is important insofar as the to be transmitted moment with the third power the diameter of the universal joints 24 and the cardan shaft 23 enlarged.
  • the drive motors 13, 14 a very large torque to transfer, u.zw. a much higher than according to the prior art, wherein as additional Advantage even a torsionally rigid drive is realized.
  • Another advantage results from installation a designed as a spring cup 37 spring damper element in the lever system of the parallel guide 25th This will dynamically act as bending forces Walzapfen acting forces, caused by the Vertical accelerations of the drive train during Rolling stock entry or exit, to a fraction of the reduced to conventional values.
  • the spring cup 37 can provided on any lever of the lever system become.
  • the spring-damper element adjustable by force.
