Definitions

  • the invention relates to a rolling stand for rolling elongated material, with a plurality of arranged in a plane, forming a central caliber opening, rotatable together with the interposition of a common rotatable drive element in the form of an internally toothed ring radially over eccentric engageable driven rollers, the roll shafts rotatable in the roller housing in eccentric bushes stored and geared together via meshing bevel gears.
  • each roller shaft In order to allow a radial adjustment of the rollers without changing the backlash of the drive bevel gears, there is arranged on each roller shaft at least one spur gear, which meshes with a arranged on a parallel to each roller shaft in the rolling housing drive shaft arranged spur gear. All drive shafts are arranged in a common second plane parallel to the first plane.
  • the eccentric or radial adjustment of the rollers arranged in the other plane is a plane over the transmission plane initiated.
  • a geared at its end adjusting spindle is rotated, the toothing engages in an outer toothing of a ring gear and this rotates coaxially to the roller shaft.
  • the ring gear is provided with an internal toothing, which meshes with the external teeth of spindle nuts, which in turn receive worm gears, which rotate all worm gears simultaneously and in the same direction when turning the spindle on the present gear connections. Due to the meshing with the worm gears spindle drives the eccentric adjustment of the rollers is carried out in the same direction and by equal amounts.
  • the invention has for its object to provide a generic rolling stand, which allows a radial eccentric adjustment of the rollers without play.
  • the bevel gears sit advantageously with a splined profile displaceable at the end of short shaft pieces whose other end is arranged with a mecanicvielkeilprofil on the roll shafts.
  • the shaft pieces are mounted by means of rolling bearings in the eccentric bushes designed as worm gears.
  • In the worm gears engage a worm, at the ends of which formed spur gears mesh with the ring gear.
  • the end faces formed so that circular contour sections (grooves, shoulders or the like), in which engage the cassettes, are arranged eccentrically to Hohlradmitte.
  • the ring gear rotates and is forced to shift the cassettes connected to the eccentric grooves or shoulders of the ring gear.
  • the centers of the roll shafts form a triangle.
  • the eccentric adjustment of the rollers changes the size of the triangle.
  • the tips of the triangle move in the direction of the bisector. In this direction, the cassettes are moved and thus also fixed therein bevel gears, which move in the splined profile of the roller shafts.
  • the one of the roller shafts is connected to a drive and provided with a drive-side bevel gear and a remote therefrom, as the only one bevel gear owning other roller shafts wave ends arranged bevel gear.
  • the drive torque introduced via the directly driven roller shaft is caused by tooth engagement on the one hand between the two pinions or internal gears of this shaft and the associated bevel gears and on the other hand distributed over the meshing of these two bevel gears, each with a bevel gear of the further roll shafts.
  • a further embodiment of the invention provides that the rollers between two worm wheels are keyed to the roller shafts, of which the rear worm gears with their respective associated spindle drives are in engagement, which in turn all with the internal teeth of a surrounding from the outside, driven to Exzenterver ein Comb the ring gear.
  • the worm wheels arranged on both sides of the rollers on the eccentric bushings are known to lead to a system which is symmetrical both in terms of design and in terms of force introduction and distribution.
  • the arrangement of the spindle drives each outside of the worm wheels, so that they simultaneously mesh with these and the ring gear, makes it possible to improve the installation and adjustment.
  • the spindle drives unlike in the prior art internal arrangement, the roll change is not in the way.
  • the roller housing In the partial cross-section through a rolling stand shown in Fig. 1, the roller housing, not shown, consists of an upper and a lower plate, which are screwed together. In the space between the plates are three offset by 120 ° to each other staggered rollers 4, 5, 6, which close the caliber 7. The rollers 4, 5 and 6 are fixed by means of feather keys 8 on roll-shaft construction executed in the roll axle construction 9, 10 and 11.
  • the roller shaft 9 is connected via a coupling 12 with a drive, not shown.
  • 11 are mounted in cassettes 14 and 15 via tapered roller bearings 13 each separately in their installed position fixed shaft end-side bevel gears 16a, 16b and 16c.
  • the directly driven roller shaft 9 has on the side facing the coupling connection 12 on a second, drive-side bevel gear 17 on.
  • the bevel gear 17 meshes with the bevel gear 16c of the roller shaft 11 and the shaft end-side bevel gear 16a of the roller shaft 9 meshes with the shaft end side bevel gear 16b of the roller shaft 10, so that there is a closed power flow.
  • the drive-side bevel gear 17 is connected via a splined profile 18 with the roller shaft 9.
  • the respective shaft end-side bevel gears 16a, 16b, 16c concentrically take short shaft pieces 21, 22 and 23, via which they are engaged with splined profiles 19a, 19b and 19c, wherein the short shaft pieces 21, 22, 23 in turn on splined profiles 20a, 20b and 20c of the roller shafts 9, 10 and 11 sit.
  • roller shafts 9, 10 and 11 executed in the plug-in axis version in the splines 18 and 19a, 19b, 19c and 20a, 20b, 20c can be moved.
  • Fig. 2 shows that in each case from outside worm shafts 25 are associated with gears 26, all together with an internal toothing owning 27, the gears 26 of the screw shafts 25 from the outside enclosing ring gear 28 mesh so that the worm shafts 25 in simultaneously with the Worm toothing of the eccentric bushings 24 and the ring gear 28 engaging construction are arranged.
  • the end surfaces of the ring gear 28 are formed so that circular contour portions 33 (grooves, shoulders or the like), in which the cartridges 14 and 15 engage by means of Mitology Divisionen 30 and 31, are arranged eccentrically to Hohlrad- or roller center 29.
  • the centers of the roller shafts 9, 10 and 11 form - as can be seen from FIG. 1 - a triangle whose size changes with the eccentric adjustment of the rollers 4, 5 and 6, whereby also the tips 32a, 32b and 32c of the triangle shift in the direction of the bisectors.
  • bevel gears 16a, 16b move , 16c and 17 in the spline profiles 18, 19a, 19b and 19c.
  • a game between the meshing of the bevel gears 16a, 16b, 16c and 17 can not occur.
