Definitions

  • the invention relates to a roll stand according to the preamble of claim 1 and is based on the prior art given by DE-A-2 304 268.
  • Roll stands of this type are intended to permit uninterrupted operation as far as possible. Therefore, the replacement of wear parts must be carried out in the shortest possible time.
  • the exchange units should be as small as possible, i. H. limit yourself to the wearing parts in order to keep the operating and maintenance costs as well as the effort for the spare parts storage low.
  • Various constructions have already become known for this purpose (DE-A-742 990, DE-A-2 304 268, US-A-3 336 781), which provide an easily releasable connection between individual parts of such a roll stand and rapid replacement enable these parts. In this case, however, relatively large housing parts, including functional parts that are subject to only slight wear, are still replaced. This then requires complex assembly, sealing and alignment work.
  • the eccentric bushings are provided on their circumference with a groove into which a wedge, which is common to the eccentric bushings and is mounted in the housing, can be inserted by means of a spindle, which axially fixes the eccentric bushings and, when pulled out, allows the eccentric bushings to be removed.
  • a housing 1 with oil bores 2 is closed at its end on the roll side with an end plate 3.
  • Two roller shafts 5 with their end 4 intended for receiving roller disks 4 passing through the end plate 3 are mounted in eccentric bushings 6, which in turn are rotatably mounted in the housing 1.
  • the roller shafts 5 carry at their other end gears 7, the external teeth of which engage with the internal toothing of wheels 8 mounted in the housing 1 concentrically with the eccentric bushes 6, regardless of the position of the eccentric bushes 6.
  • the wheels 8 are seated on intermediate shafts mounted in the housing 1 9, which are connected to one another via spur gears 10. One of the two intermediate shafts 9 is connected to the roller drive.
  • the roll adjustment is carried out symmetrically by rotating the eccentric bushes 6 in opposite directions via an adjusting spindle 11 with two worm gears 12 and two adjusting wheels 13.
  • Each of the two eccentric bushes 6 is provided with a circumferential groove 14 into which a common wedge 15 engages, which is slidably mounted in the housing 1 via elongated holes 16 and pins 17.
  • the eccentric bushes 6 are fixed in the axial direction by the wedge 15 in the housing 1.
  • the wedge 15 can be pulled out of the grooves 15 by means of a spindle 18. He then releases the eccentric bushes 6 so that they can be individually and collectively pulled out and exchanged on the front side from the housing 1, in each case together with the roller shaft bearings, the roller shafts 5 and the gear wheels 7.
  • the opening in the end plate 3 need only be as large as the front bearing diameter D of the eccentric bushes 6, since the remaining parts of the exchange units, i.e. the eccentric bushes 6 themselves, the ring gear 19 with which the adjusting wheels 13 mesh, and also the toothed wheels 7 are dimensioned such that they have no larger diameter or projection.

1. Cage de laminoir comportant des cylindres qui sont montés en porte-à-faux sur paliers et peuvent être serrés les uns contre les autres, et dont les arbres (5, 5) sont montés sur paliers dans des douilles à excentrique (6, 6), montées de manière à pouvoir tourner dans un bâti (1) et reliées, à leurs extrémités situées en face des cylindres, par des roues dentées (7, 8) de manière à être entraînés, à des arbres intermédiaires (9, 9) montés également sur paliers dans le bâti (1), les douilles à excentrique (6, 6), avec la totalité des cylindres, des paliers d'arbres de cylindres et des roues dentées, étant introduites dans le bâti, à partir de sa face frontale, de manière à pouvoir en être enlevées facilement, et les diamètres des roues dentées (7, 8) et des douilles à excentrique (6, 6) étant plus petits que l'extrémité du bâti (1) située du coté des cylindres, caractérisée en ce que, les douilles à excentrique (6, 6) étant entraînées, pour leur rotation, par l'intermédiaire de couronnes dentées (19, 19) montées sur elles, le diamètre de celles-ci est également plus petit que l'extrémité du bâti (1) située du côté des cylindres, et en ce que chacune des douilles à excentrique (6), en même temps que le cylindre, l'arbre de cylindre (5), les paliers de cylindre, la roue dentée (7) et la couronne dentée (19), peut être introduite et mise en place ou enlevée individuellement par une ouverture qui est ménagée dans la face frontale du bâti (1) et dont les dimensions correspondent à la douille à excentrique, à la roue dentée et à la couronne dentée.
2. Cage de laminoir selon la revendication 1, caractérisée en ce que les douilles à excentrique (6) comportent, à leur périphérie, une rainure (4) dans laquelle un coin (15), commun à toutes les douilles à excentrique (6) et monté sur paliers dans le bâti, peut pénétrer sous l'action d'une broche (18), de manière à fixer les douilles à excentrique (6) dans le sens axial, et en être retiré de manière à permettre l'enlèvement des douilles à excentrique (6).
