Definitions

  • the invention relates to an adjusting device for the adjustment of chocks in a rolling stand with a worm shaft, the worm of which engages in an axially supported worm wheel which engages with a nut thread in a threaded section of a non-rotatable, longitudinally displaceable adjusting spindle.
  • Adjustment devices are required in particular if the profile of the roll gap is to be changed, for example by setting work rolls, or if, for example in accordance with “Production of Cold-Rolled Strip”, Part 1, Verlag Stahleisen mbH, Düsseldorf, 1970, pages 309 and 310, an additional support of a work roll of small diameter is carried out by horizontal displacement against the plane having the axes of the support rolls.
  • an adjustment gear according to the upper handle of claim 1 for the radial adjustment of rolls of roll stands is known.
  • the adjustment gear consisting of worm gear and gearing-connected pressure spindles, is arranged below or above the stand frame or in this.
  • the setting gear can also be structurally divided into a worm drive and a pressure spindle connected to it in a geared manner.
  • a worm shaft with a worm is provided, the worm engaging in a worm wheel and this worm wheel having a nut thread which engages in the threaded section of a non-rotatable but axially displaceable adjusting spindle.
  • a lubricant chamber comprising the worm gear and the pressure spindles including the bearings is provided with passage channels through the gear housing upwards and downwards, wherein fans or plugs can be inserted into the passage channels depending on the operating position of the gearbox.
  • the worm gear and the pressure spindle connected to it in a scaffold should be housed in separate housings, the worm gear is surrounded by a closed lubricant chamber, while the pressure spindle is axially provided with a passage channel for the lubricant.
  • Wedge adjustments are known for this purpose, in which, however, the actuating stroke and thus the size of the adjusting device increase with an increasing useful stroke, so that such drives have proven themselves for a relatively small useful stroke, but at higher displacements to be required, however, undesirably large adjusting movements are required.
  • Another disadvantage is that a pure displacement-causing actuating movements are avoided anyway because of the large space requirement of the actuators in this case, and therefore a rotating actuating movement is recommended, which is transmitted to the wedge surfaces via a screw spindle encompassed by nuts.
  • Hydraulic adjusting devices have proven to be relatively complex in practice, since the desired compact design requires high pressures, the control and control of which are already difficult, and in general an encoder which monitors the travel path is also required without a purely translational movement being ensured is.
  • the invention is therefore based on the object to provide a compact adjusting device for the horizontal adjustment of chocks in rolling stands, the actuating stroke of which is easy to monitor or to determine and to specify which predetermined adjustment paths are largely rigid without elastic compliance and which are capable is to carry out practically purely translatory positioning movements.
  • a device characterized in that the worm shaft has two worms, each worm engaging in two mutually opposite worm wheels arranged symmetrically to the worm shaft, and each worm wheel being connected in a gearbox to an adjusting spindle and the Free ends of the adjusting spindles support a common pressure plate with which they are connected in a rotationally fixed manner, for example using grooved pins. Due to the double reduction via the screw connection and the threaded connection, easily manageable horizontal positioning movements for rollers with high angular positions at low torque are guaranteed and it can be precisely defined within a wide stroke range Employment can be specified.
  • Relief of the worm shaft in connection with the possibility of a further exact alignment of the adjusting plate to be shifted is achieved in that the worm engages in two mutually opposite worm wheels arranged symmetrically to the worm shaft. Finally, the translational movement is largely secured under load distribution in that the worm shaft engages in two worm wheels.
  • the desired exact horizontal adjustment combined with a simple construction of the adjustment device, can be achieved in that the adjustment spindles support a common pressure plate with which they are connected in a rotationally fixed manner, whereby a separate longitudinal guidance of the individual adjustment spindles is not necessary.
  • the worm shaft between the two worms is additionally supported by a further bearing that allows axial play.
  • a housing 2 which is reinforced by ribs 1 and which, according to FIG.
  • Rolling bearings 5 to 7 are used in openings in the flanks and a web 1 connecting ribs, of which the bearing 5, which is formed by two symmetrical tapered roller bearings, acts as a thrust bearing, while the cylinder bearings 6 and 7 act as radial bearings.
  • a worm shaft 8, which is equipped with two worms 9 and 10, runs in these bearings, also supported in the center. In each of these worms, two worm wheels mounted opposite one another engage in one of the worms, so that the normal forces which are caused during the actuation processes and which are normal to the worm shaft compensate one another.
  • the worm wheels 11 are mounted in a defined manner; two conventional radial bearings 13 and 14 each hold a worm wheel 11 in its axis and in defined engagement with the associated worm 10, while two axial bearings 12 and 15 exclude axial movements of the worm wheel and support the actuating forces transmitted to the worm wheels.
  • the worm wheels have a continuous bore, within which a section of a nut thread is provided.
  • the bores of the worm wheels 11 are penetrated by adjusting spindles 17 which are guided in recesses 16 of the housing 1 and which engage with a threaded section 18 in the nut thread of the worm wheel 11.
  • Defined displacements of the adjusting spindles 17 are secured by their threaded section 18, which is supported in the worm wheel 11, as well as by their exact guidance in the recess 16 securing guide rind 19 and 20, which are each equipped with seals for secure closure in the housing.
  • One end face of the adjusting spindles 17 designed as a hollow shaft is in each case provided with notch pins 21 which engage in flanges 23 which in turn are connected to a common pressure plate 24 which carries out the adjusting device.
  • An additional securing of this connection is brought about by the adjusting spindles 17 penetrating and engaging in the flanges 23 bolts.
  • the adjusting spindles 17 are secured against rotation.
  • the direction of rotation of the drive can easily be taken into account: opposite worm wheels 11 rotate under the influence of the drive through the assigned worm in the opposite direction of rotation.
  • this is taken into account by the fact that the worm wheels and adjusting spindles provided on a common side of the worm shaft have threaded sections 18 or nut threads formed in the same direction, while the worm wheels and adjusting spindles provided on the opposite side of the worm shaft are equipped with opposing threads.
  • a symmetrical drive of two gears is easily possible if the respective thread senses are exchanged for those of the adjusting device working with it.
  • two opposing Devices the same direction of adjustment are effected if in one case above the worm shaft to the left and below the worm shaft right-hand thread of the worm wheels 11 and the adjusting spindles 17 are provided, while in the other adjusting device above the worm shaft right and below the same left-hand thread are arranged.
  • this has the further advantage that even in the case of an inverse actuator, the adjusting devices are constructed with the same parts, so that the manufacture, but also the spare parts inventory and, if necessary, repair are rationalized by reducing the parts to be stored or installed.
  • Grooves 25 in connection with springs ensure compliance with specified positions or positions in the stand window or a recess thereof.
