Definitions

  • the invention relates to a device for driving the vertical rolls of a universal roll stand in at least one direction of rotation, the vertical rolls being mounted in chocks.
  • the invention has for its object to avoid the disadvantages of the known drag drives for vertical rollers and to achieve a positive drive of the vertical rollers.
  • a universal roll stand for rolling I-sections 1, shown schematically in FIG. 1, is known to comprise two horizontal rolls 2 and two vertical rolls 3, which are rotatably mounted on a fixed support shaft 4 within a mounting piece 8 via roller bearings 6 and 7.
  • an electric motor is installed in each chock 8, the stator of which is formed by an annular collar 4a of the support shaft 4, in that the annular collar 4a is provided with the primary armature 4b through which current flows.
  • the power supply not shown, takes place through the fixed support axis 4.
  • the vertical roller 3 is designed as a rotor of the electric motor, in that it carries the secondary windings 5. Since the vertical rollers 3 designed as the rotor of the electric motor expediently consist of readily magnetizable steel, they are armored with a rolled-on roller ring 9 made of wear-resistant material.
  • a vertical roller 10 is rotatably mounted within a chock 11, which can be set against the rolling stock via two plungers 12, 13 of the vertical adjusting device, not shown. Between the plungers 12, 13 is a box 11a open towards the chock as a housing flange-like extension of the chock 11, which receives a hydraulic motor 14, the pressure lines 15 are led out of the housing-like extension 11a.
  • the hydraulic motor 14 is provided with a drive spur gear 16, from which the vertical roller 10 is driven directly via an intermediate spur gear 17 mounted in the chock 11.
  • the vertical roller is provided on one end face with an externally toothed drive ring 18 which is in engagement with the intermediate spur gear 17.
  • the intermediate wheel 17 is rotatably connected to a shaft 19 mounted at both ends in the chock 11 which, for reasons of drive symmetry, carries a further intermediate spur gear 17 'which engages with a further drive ring 18' of the vertical roller 8.
  • the shaft 19 passes through a filler piece 20 which is inserted into a radial installation opening 21 of the fitting 11 corresponding to the diameter of the intermediate spur gears 17, 17' and radially through the inserted shaft 19 is fixed.
  • the vertical roller 23 is mounted in a chock 24 which is provided with two cantilever-like extensions 24a which, with an outer support wall 25, form a housing which is open laterally outside the chock 24, as shown in FIG. 6. Between these extensions 24a, a slider 26 is radially positively guided, which extends through a radial installation opening 27 of the chock 24.
  • the slider 26 carries a hydraulic motor 29 provided with a drive spur gear 28.
  • the drive spur gear 28 is in engagement with an intermediate spur gear 30 which is rotatably mounted in the slider 26 via a shaft 31.
  • the shaft 31 is rotatably connected to a friction wheel 32 which drives the vertical roller 23 on its outer circumference.
  • the friction wheel can be sustainably pressed against the vertical roller 23, supported on the support wall 25 of the housing-like extension 24a, by means of two cylinders 33 arranged on the side of the hydraulic motor 29, which are connected to the slider 26 via joints 34 connected and the piston rods 35 are connected to the support wall 25 via flange cover 36.
  • the hydraulic internal drive of the vertical roller 40 according to FIGS. 7 and 8 does not require a housing-like extension of the chock 41, since the hydraulic motor 43 is inserted into the non-rotatable support axis 42 of the vertical roller.
  • the drive goes from a drive spur gear 44 coaxial with the hydraulic motor 43 via a first and a second intermediate spur gear 45 and 46 to an internally toothed drive ring 47 of the vertical roller 40.
  • the hydraulic motor 43 is eccentrically in the support axis 42 used to create space for a shaft 48 inserted in the opposite eccentric manner in the support shaft 42 for mounting the first intermediate spur gear 45.
  • the support shaft 42 is provided with a radial installation opening 49 (FIG. 8).
  • the support shaft 42 is surrounded by a support sleeve 50 which is connected in a rotationally fixed manner to the non-rotatable support shaft 42 via a feather key 51.
  • This support sleeve 50 has a collar 53 (FIG. 7, right half) arranged symmetrically to the transverse plane Q, against which the inner rings 54a of two oblique roller bearings 54 are braced.
  • this collar 53 also fulfills the task of holding the shaft 52, in which the support sleeve 50 and the collar 53 are provided with a radial installation opening 55 (FIG. 8) in such a way that the shaft 52 faces outward in flanks 53a of the Federal 53 and can be clamped inwards by bearing cover 56 (Fi.g 8).
  • the internally toothed drive ring 47 of the vertical roller 40 is not molded onto the roller body, but rather a stepped ring which is connected via screws 57 to an inwardly projecting collar 40a of the vertical roller.
  • the collar 40a and the outwardly projecting step 47a of the internally toothed drive ring 47 serve as a common abutment for bracing the outer rings 54b of the two inclined roller bearings 54.
  • All solutions with a hydraulic drive according to FIGS. 2 to 8 make it possible to mount the spur gears in chambers which are closed to the outside and which can be sealed to the outside.
  • a guided lubricating oil in the exemplary embodiment according to FIGS. 7 and 8, for example, via an inner bore 48a of the shaft 48, can even be used to lubricate the roller bearings 54.
  • the bracing of the outer races 54b of the bearings against the collar 40a or the step 47a also has a sealing function.
