Definitions

  • Planetary diagonal rolling mills are used for the rolling out of full and hollow cross sections, in particular for the strong cross-section reduction as so-called high reduction rolling mills, in order to bring the material to be rolled out considerably in a single pass to the desired final cross section.
  • the rolling forces to be applied are correspondingly high.
  • the planetary diagonal rolling mills usually consist of three rolling heads, each of which carries a tapered roller and which are seated in a rotor with which they rotate around the rolling stock, so that the tapered rollers can reduce the cross-section.
  • the tapered rollers are arranged with their axes inclined to the rolling stock axis and their axes cross the rolling stock axis at a short distance.
  • a hollow shaft through which the rolling stock runs to the tapered rollers, there is a sun gear on which planet gears roll, which drive the respective roller shaft via an intermediate gear, a bevel pinion and a bevel gear.
  • Roll adjustment and inclination, rolling stock diameter and speed of the rotor can only be set for one ratio so that the rolling stock does not rotate about its axis.
  • the hollow shaft traversed by the rolling stock is correspondingly turned forwards or backwards.
  • the rolling heads rotating around the rolling stock with the rotor are of particular importance as they are exposed to high rolling forces and high centrifugal forces.
  • the centrifugal forces are directly proportional to the distance at which the components are arranged to the rolling stock axis and they increase with the square of the angular velocity, which directly determines the throughput of the rolling mill. It follows from this that the arrangement of the components, in particular the heavy components, should take place at a short distance from the axis of the rolling stock, as is permitted by the roller geometry caused by the diameter of the rolling stock and reduction of the pass.
  • a design of the rolling head has proven to be favorable, as described in the preamble of claim 1 and through the conference report on the ILAFA Rolling Mill Congress, published by the Instituto Latinoamericano del Fierro y el Acero, May 1980, page H 9/10, Figura 26, is published.
  • a radial bearing and a thrust bearing are provided in a very powerful design, in which one end of the shaft is supported, which at this end carries the tapered roller while the roller shaft at its other end rotatably, but axially displaceably in that the bevel gear of the roller drive is seated in the roller head housing.
  • a support ring for the axial bearing is arranged between the bearings (radial and axial bearings) and the bevel gear, which is rotatably seated in the roller head housing and can be rotated for the axial adjustment of the roller.
  • To rotate the support ring it can be coupled via a clutch to the bevel gear driving the roller, while the support ring is fixed non-rotatably in the roller head housing during rolling via the same clutch.
  • Ria acts as a support ring, a bushing which is provided with the Stele thread on the outside and accommodates the bearings (radial and axial bearings) in its bore.
  • the design of the support ring as a bushing requires a roller head that is twice the wall thickness of the bushing or, given the dimensions of the roller head, only allows bearings that have to remain smaller than bearings of maximum conceivable diameters by twice the wall thickness of the bushing.
  • the aim of the invention is to design the mounting and positioning of the shafts that carry the tapered rollers overhung and that have an axially and radially compact construction, i. H. in the latter results in a construction without components that are not directly load-bearing.
  • This goal is achieved by the design of the rolling heads having the characterizing features of claim 1. Further expedient refinements of the invention can be achieved with the features of the special designs specified in claims 2 to 6.
  • FIG. 1 show exemplary embodiments of the invention and are limited to the representation of the roller heads in axial section, the roller heads being seated in three in a rotor — indicated and indicated by 1 — and rotating with it in a stator (not shown).
  • Structures of rotors and stators are known, for example from the publication already mentioned for the prior art or from the prior art according to DE-A-3 112 781.9 or DE-A-3 113 461.0.
  • a roller head 3 with its cylindrical extension 4 is pivotably seated in a bore 2 of a rotor indicated by 1.
  • an intermediate shaft 5 is mounted in the pivot axis, which engages with an intermediate gear 6 in a planet gear, not shown, mounted in the rotor 1 and rolling on a sun gear, also not shown, whereby the intermediate shaft 5 when the rotor 1 and / or the sun gear is rotated.
  • the intermediate shaft 5 is further provided with a bevel pinion 7 which engages in a bevel gear 8.
  • the bevel gear 8 is connected to a hollow shaft 9 and is mounted with it by radial bearings 10 and 11 and an axial bearing 12 in the roller head housing 13.
  • the hollow shaft 9 is provided over the length of its bore with an internal toothing 14, in which the correspondingly toothed end of a roller shaft 15 rotates but is longitudinally displaceable and centered.
  • the front end of the roller shaft 15 is supported via a radial bearing 16 and an axial bearing 17 in the roller head housing 13.
  • a pin 18 of the roller shaft 15 protruding from the radial bearing 16 carries a tapered roller 19 on the fly.
  • the tapered roller 19 is provided with an inserted ring 20, which has end teeth 21 and is secured against rotation by pins 22.
  • An internally toothed cap 23 is placed on the externally toothed pin 18 of the roller shaft 15, which cap defines the inner ring of the bearing 16 axially relative to the roller shaft 15.
  • the cap 23 is also provided with a spur toothing corresponding to the spur toothing 21 and thus establishes the rotationally fixed connection of the tapered roller 19 with the roller shaft 15.
  • the tapered roller 19 is held on the roller shaft 15 by a screw 24 which is screwed into a nut piece 25, into which one end of a tie rod 26 is also screwed, the other end of which is screwed into a nut 27.
  • the nut piece 25 is designed as an annular cylinder for receiving an annular piston 28, by the action of which the tie rod 26 is stretched, so that after tightening the screw 24 and then relieving the annular piston 28, the tension force of the tie rod 26, the tapered roller 19 via the ring 20 and Cap 23 clamped against the end face of the roller shaft 15 at the pin 18 thereof.
  • the perforated roller shaft 15 is closed at the end facing away from the tapered roller 19 with a cover 29, the cover 29 having a bore as a passage for a spring bolt 30.
  • a spring 31 in the bore of the roller shaft 15 is clamped between the cover 29 and a collar 32 of the spring bolt 30, for which purpose the spring bolt 30 with a nut 34 seated on its threaded shaft 33 via an axial bearing 35 on a roller head housing 13 on that of the tapered roller 19 opposite end closing cover 36 supports.
  • a support ring 40 is provided for the axial bearing 17, which is provided with an external thread 41 and is rotatably seated in the threaded bore of an insert ring 42 relative to the roller head housing 13.
  • the insert ring 42 is secured against rotation in the roller head housing 13 and in the insert ring 42 the pressure ring 17 ′ of the axial bearing 17 is in turn secured against rotation by round wedges 43.
  • the support ring 40 is provided with a spur toothing 44 and can be coupled via a rotationally fixed but axially displaceable coupling ring 45, which has a corresponding spur toothing to the spur toothing 44 of the supporting ring 40, so that with the rotation of the roller shaft 15 also Support ring 40 is rotated.
  • a ring 46 is fastened on the roller shaft 15, which receives ring pistons on both end faces in turns, which, by alternating action, engage the coupling ring 45 into the front toothing 44 of the support ring 40 or disengage from it.
  • a support ring designated 50 is provided for the axial bearing 17, which is provided with an external thread 51 and is rotatably seated in the threaded bore of an insert ring 52 relative to the roller head housing 13.
  • the insert ring 52 is secured against rotation in the roller head housing 13 and in the insert ring 52 the pressure ring 17 ′ of the axial bearing 17 is in turn secured against rotation by round wedges 53.
  • the support ring 50 is divided, the inner ring 54 being seated in a rotationally fixed but axially movable manner with the support ring 50 and being provided with spur gears 55 and 56 on both end faces.
  • the axial adjustment takes place via a claw 57, which can be moved in a known manner, not shown here, parallel to the axis of the roller shaft 15 and acts on the clutch disc 58, which is part of the inner ring 54 of the support ring 50.
  • the spur toothing 55 of the inner ring 54 engages in a corresponding spur toothing of a coupling ring 59 on the inner edge of the ring of the bevel gear 8 and thus connects the bevel gear 8 with the support ring 50 for the axial adjustment of the axial bearing 17 with the roller shaft 15 and the bevel roller 19
  • the end toothing 56 engages in the corresponding end toothing on the coupling ring 60, which on the one hand is non-rotatable but axially displaceable in the pressure ring 17 'of the axial bearing 17 and on the other hand rotatable is held axially immovably on a guide sleeve connected to the ring of the bevel gear 8, so that the support ring 50 is thereby secured against unintentional rotation.
