Definitions
- the invention relates to a roll stand, in particular for caliber and sizing of rod-shaped or tubular rolling stock, with three forming a common caliber opening driven rollers, the gears of which mesh with one another via meshing gears connected drive shafts in a common transverse to the rolling direction Level are arranged.
- Rolling stands of this type are, for example, in the German published application 37 03 756. You receive the three rollers arranged in a star shape Drive torque via spur gear teeth, the distribution of the Driving torque from one driven roller shaft to the other Roller shafts are carried out via bevel gear pairs, the bevel gears on each of the Roller shafts are arranged.
- the object and aim of the present invention is to provide the gear train on one Roll stand with three rolls of the generic type to improve so that the input and and forwarding the drive torque is simplified without rolling accuracy deteriorate and on the exact setting of the meshing with each other Abandon gears.
- the elaborate assembly and disassembly processes should simplified and maintenance should be improved.
- the gearbox sub Maintaining the technical function - much cheaper to create be.
- the invention proposes that the two intermeshing gears of two adjacent drive shafts Form angular gear with crown gear teeth.
- Angular gears with crown gear teeth are very old, their application goes back to antiquity.
- the hallmark of such gears is Use of at least one cylindrical arranged coaxially to the drive shaft Ritzels, which meshes with a crown gear toothed on the face, with the axes of the pinion from the parallels are inclined by an angle up to 90 ° can.
- a cylindrical pinion with involute teeth of a drive shaft with a matching toothed crown gear of the neighboring one at 60 ° to the first Drive shaft combs inclined drive shaft arise as a result of the cylindrical Pinion no more axial forces in the drive shafts toothed with these pinions, see above that these drive shafts only need to be mounted radially.
- the means a very simple construction of the roller bearing and thus a considerable one simplified assembly and disassembly of these gear parts. Elaborate setting and Fitting work that required high accuracy with bevel gear teeth and very were time-consuming, because the axial infeed of the cylindrical pinion was too the beveled crown gears do not require high accuracy. Leave the sprockets form separately from the associated roller mounts, whereby the Have component costs reduced further.
- a sizing mill for pipes according to the prior art is rough shown schematically, in its roll stand 4 on the same level arranged three drive shafts 1, 2, 3 the rollers 5a, 5b, 5c to each other drive shafts inclined by 60 ° are arranged.
- the rollers 5 a to 5 c are of this type calibrated so that, as can be seen at 6, they form a closed caliber.
- the pin 1 a is connected to the drive, not shown, are the bevel gears 7 a shrunk, which in turn with the bevel gears 8 Combine drive shafts 2 and 3 and thereby at 1 a into drive shaft 1 initiated drive torque, on the drive shafts 2 and 3 of the rollers 5 b and 5 c to distribute.
- the drive shaft 1 is on both sides of the bevel gears 7 a in radial bearings 9 supported; due to the symmetrical arrangement of the bevel gears 7 a Drive shaft 1 largely free of axial forces. Not so the drive shafts 2 and 3. These waves are due to the toothing of the bevel gears 8 through in the axial direction acting thrust loads significantly, in additional thrust bearings 10th must be included.
- the entire gear of the mill stand builds easier and lighter, is cheaper to manufacture and easier to build waiting.
- the setting of the pinion 14 on the crown gears 13 is easy with simple means possible because no high accuracy in setting and Assembly work is required.
- the pinion 14 are designed as separate components that support the rollers 5 b, 5 c Hollow shafts 15 can be screwed on the end face at 16. In the state of the art 2, however, the hollow shafts 15 were in one piece with the bevel gears 8 executed and correspondingly complicated and expensive.
