Definitions

  • the invention relates to a device for driving a pair of vertical rollers or their support shafts, which are mounted in mutually displaceable bearing chocks, in which the pins of the vertical rollers or the support shafts are coupled with drive gear shafts, each in a connected to the chock and this sliding transmission housing to store.
  • the two vertical rollers from above into the, in a guide frame horizontally movable and against each other arranged adjustable bearing chocks are used.
  • coupling sleeves can be slid onto their upwardly projecting drive pins, which are rotatably driven via articulated spindles articulated on them and one, this common transmission arrangement.
  • the vertical rollers are each mounted in a horizontally displaceable support housing and coupled with their downwardly directed drive pin with a gearbox, whose housing is connected to the support housing of the vertical rollers and slidable.
  • the two support housing-housing combinations are against each other and anstellverschiebbar their vertical rollers are driven by a sliding coupling arrangement of a respective drive unit, which is arranged laterally below the respective combination.
  • JP 57190703 device shows a pair of horizontal rollers, each of which is mounted on a roller follower shaft which supports in a bearing housing, which in turn is fixedly connected to a gear housing with flanged drive motor. Both housing-motor combinations are pivotally connected to each other. The employment of the rollers is effected by pivoting this housing-motor combination. For use in wire rod mills, this combination can be brought by means of corresponding support frame in different angular positions, wherein the roll center shafts take a corresponding angular position to the rolling line.
  • the document DE-A-2 247 622 shows an apparatus for driving a pair of vertical rollers or their support shafts supported in mutually displaceable bearing chocks, in which the pins of the vertical rollers or the support shafts can be coupled to drive gear shafts which are each connected to the bearing chocks and store with these sliding gear housing, wherein the drive gear shafts are formed as vertically mounted, one-sided bevel gear, the bevel gears mesh with bevel gears of horizontally coaxially mounted in the respective gear housing bevel gear shafts in the form of single-sided bevel gear hollow shafts.
  • the invention has for its object to improve the generic devices so that in addition to a significantly lower construction costs and with only one drive unit for the device a fast and accurate roller adjustment is made possible.
  • the drive gear shafts are designed as vertically mounted one-sided bevel gear shafts whose bevel gears mesh with bevel gears of horizontal, coaxially mounted in the respective Geretetraggephase, also one-sided bevel gear shafts in the form of bevel hollow shafts, the one, an inside splined shaft profile connected to the outside spline shaft profile of a, arranged between two hollow shafts floating intermediate shaft, are coupled to the drive unit.
  • the vertically mounted bevel gear shafts may be formed at their ends remote from the bevel gears as a hit for the pins of the vertical rolls.
  • the two vertical rolling rings VWR1 and VWR2 according to FIG. 1 are pushed onto roller support shafts WTW1 and WTW2, which respectively support the bearing chocks LES1 and LES2, which are horizontally displaceable relative to each other and away from each other, in a manner not shown.
  • two gearboxes GG1 and GG2 are arranged and positively connected to the respective bearing chock LES1 or LES2.
  • One of the bevel hollow shafts KHW3 is axially slidably coupled to a drive spindle ASP.
  • Both bevel hollow shafts KHW3 and KHW4 each have on the inside a spline profiling ZPI3 or ZPI4.
  • the bevel gear shafts KW1 and KW2 stored in the two gearbox housings GG1, GG2 can follow the horizontal displacement motions of the bearing chocks LES1 and LES2 and the gearbox housings GG1 GG2 caused by the vertical rolling rings VWR1, VWR2, because the bevel helical shafts KHW3 and KHW4 over their toothed shaft profile coupling with the intermediate shaft ZW remain permanently connected drive.
  • the vertical bevel gear shafts KW1 and KW2 are facing away from the bevel gears KR1 and KR2 and the Walzingagwellen WTW1 and WTW2 facing ends as a hit TR1 or TR2 for receiving the pin ZA1 and ZA2 of the roll support shafts WTW1 or WTW2 formed.
