Definitions
- the invention relates to a roll stand for rolling elongated material, with several arranged in one plane, forming a central caliber opening, with the interposition of a common, rotatable drive element in Form of an internally toothed ring gear radially adjustable via eccentric driven rollers, their roller shafts in the roller housing in eccentric bushings rotatably mounted and geared via intermeshing bevel gears are interconnected.
- the ring gear is provided with an internal toothing, which meshes with the external teeth of spindle nuts, which in turn Take up worm drives that are present when the spindle is turned Gear connections all worm drives simultaneously and in the same direction twist. Due to the spindle drives meshing with the worm wheels the eccentric adjustment of the rollers in the same direction and around equal amounts carried out.
- the invention has for its object to a generic roll stand create that allows the eccentric adjustment without backlash and also smaller can be built.
- the bevel gears separately in cassettes which are forcibly displaceable by mechanical coupling to the ring gear are stored.
- the bevel gears are advantageously slidable with a multi-spline profile at the end of short wave pieces, the other end with a Internal spline is arranged on the roller shafts.
- the shaft pieces are by means of roller bearings in the eccentric bushes designed as worm gears. Snails engage in the worm wheels, trained at their ends Comb the spur gears with the ring gear.
- the end faces that circular contour sections (grooves, paragraphs or the like) into which the Intervene cassettes, are arranged eccentrically to the ring gear center.
- the ring gear turns and are forcibly those with the eccentric grooves or shoulders of the ring gear connected cartridges moved.
- the centers of the roller shafts form a triangle.
- the tips of the triangle move in Direction of the bisector.
- the cassettes are also in this direction shifted and thus also the bevel gears fixed therein, which are in the Move the multi-spline profile of the roller shafts.
- one of the roller shafts is connected to a drive connected and with a drive-side bevel gear and one of them removed, like the other roller shafts with only one bevel gear, on the shaft end arranged bevel gear provided. That about the directly driven
- the drive shaft initiated drive torque is due to the meshing of the teeth between the two pinions or internal gears of this shaft and the associated ones Bevel gears and on the other hand via the meshing of these two bevel gears distributed with one bevel gear each of the other roller shafts.
- roller shafts are preferably designed in thru-axle design and via splined shaft sections or a splined shaft connection with the bevel gears and connected by these picked up short shaft pieces the roller shafts can be easily removed or removed from the stand disassemble and cover the different pipe dimensions Minimize the number of scaffolds. Because after removal, the roller shafts need by changing the three roller bodies only with the required new caliber rollers equipped and inserted into the bevel gears remaining in the frame become.
- rollers between each two worm wheels are wedged on the roller shafts, of which the rear worm wheels with spindle drives assigned to them are, in turn, all with the internal toothing of an outside, Comb the driven ring gear for eccentric adjustment.
- the arrangement of the spindle drives in each case on the outside of the worm wheels, so that they are simultaneously with these and Combing the ring gear makes it possible to improve installation and adjustment.
- the spindle drives are different than in the state of the Technology inside arrangement, not in the way when changing rollers.
- Fig. 1 In the partially sectioned cross section shown in Fig. 1 consists of a roll stand the roller housing, not shown, of an upper and a lower Plate that are screwed together. In the space between the plates three rollers 4, 5, 6 offset from one another by 120 ° are arranged, which the Close caliber 7.
- the rollers 4, 5 and 6 are by means of parallel keys 8 in thru-axle construction executed roller shafts 9, 10 and 11 attached.
- the roller shaft 9 is via a clutch 12 with a drive, not shown connected.
- 11 are in cassettes 14 and 15 via tapered roller bearings 13 shaft end-side bevel gears fixed separately in their installation position 16a, 16b and 16c stored.
- the directly driven roller shaft 9 has on the side facing the coupling connection 12 a second drive side Bevel gear 17 on.
- the bevel gear 17 meshes with the bevel gear 16c Roller shaft 11 and the shaft end bevel gear 16a of the roller shaft 9 meshes with the shaft end bevel gear 16b of the roller shaft 10, so that a closed Power flow is present.
- the respective bevel gears 16a, 16b, 16c on the shaft end are concentric short shaft pieces 21, 22 and 23 on which they with multi-spline profiles 19a, 19b and 19c are engaged, the short shaft pieces 21, 22, 23 in turn sit on splined profiles 20a, 20b and 20c of the roller shafts 9, 10 and 11.
- rollers 4, 5 and 6 The installation and removal of the rollers 4, 5 and 6 is achieved in that the Thru-axle version with roller shafts 9, 10 and 11 in multi-spline connections 18 and 19a, 19b, 19c and 20a, 20b, 20c can be moved.
- the roller body is on both sides on the roller shafts 9 and 10 and 11 eccentric bushes 24 with it trained worm teeth arranged.
- Fig. 2 shows that each from the outside worm shafts 25 with gears 26 are assigned, all in common with an internal toothing 27, the gears 26 of the Combing worm shafts 25 from the outer ring gear 28 so that the Worm shafts 25 in simultaneously with the worm teeth of the eccentric bushes 24 and the ring gear 28 engaging construction are arranged.
- the end faces of the ring gear 28 are designed so that circular contour sections 33 (grooves, shoulders or the like) into which the cassettes 14 and 15 engage by means of driver pieces 30 and 31, eccentrically to the ring gear or Rolling center 29 are arranged.
- the centers of the roller shafts 9, 10 and 11 form - 1 can be seen - a triangle, the size of which changes with the eccentric adjustment of the rollers 4, 5 and 6 changes, which also changes the tips 32a, Shift 32b and 32c of the triangle in the direction of the bisector.
