Definitions

  • the invention relates to a roller arrangement for a rolling mill, in particular for a planetary cross roll mill with a roll arranged on a roll shaft, which is detachably connected to the roller shaft, being between the roller shaft and roller means for the positive transmission of a drive torque are arranged by the roller shaft on the roller.
  • rolls with a tapered outer contour must be used so arranged on a roller shaft that a reliable It is possible to introduce the drive torque from the roller shaft to the roller is, however, a roll can be changed.
  • Another solution provides for the attachment via claws on the front after Key principle to be carried out by a central screw in the roller being held.
  • Voith spur gears are used strong axial forces that have to be absorbed additionally.
  • the design of this solution is also relatively complex in terms of manufacturing of hollow shaft, tie rods and gear rings, which are required for the implementation become. Hydraulic tools are also required to secure the tie rod to tension or loosen. Another disadvantage is that this solution only can then be used when a gear coupling at the employment of the Rolling head is provided. When using a hydraulic mandrel on the employment the tie rod cannot be used.
  • claw attachment it is disadvantageous that the claws are manufactured is relatively expensive. As a rule, four are distributed evenly over the circumference arranged claws used, but mostly do not wear evenly, which is due to manufacturing tolerances. This results in high wear or an overload of the load-bearing surfaces. In the claw version the bending forces continue to be absorbed by two short cylindrical seats. The roller sits very firmly on these seats and must therefore be installed be warmed up. It is particularly disadvantageous that the disassembly because of the tight fit of the roller is difficult; it must be done immediately after the machine has come to a standstill be removed while still warm. Also has been used the claw attachment showed that the bending forces the cylindrical Wear seats on the roller shaft very quickly. Due to the relatively complex After all, the production of the claws makes the roller very expensive as a wearing part.
  • the invention is therefore based on the object of a roller arrangement of the generic type Art in such a way that the above disadvantages avoided can be.
  • it is intended for optimal transmission of the Torque and bending loads in rolling operation as well as a simple roll change become possible; the parts required for the roller arrangement, in particular the roller should continue to be inexpensive to manufacture.
  • the toothed rings are each in the axial end region of the roller shaft or roller are arranged.
  • the teeth of the toothed rings can be designed as straight teeth; there multi-spline teeth according to DIN 5480 are particularly suitable.
  • At least one of the toothed rings can according to a further development by means of pins on the roller shaft or on the roller rotatably to be ordered. It is advantageously provided that the axis of the pins is arranged parallel to the axis of the roller shaft or roller.
  • roller has a tapered Centering is arranged on the roller shaft.
  • conical centering has a length, which is at least 30% of the axial extension of the roller.
  • the roller can be connected to the roller shaft by means of a screw connection his.
  • the screw connection preferably consists of a single one Screw which is arranged coaxially to the roller or roller shaft.
  • roller is not drawn off warm must be used because the taper seat on the roller shaft is not self-locking. equally no heating of the roller is required when pulling on the roller.
  • the roll change is further favored by the fact that no tools (hydraulic Pulling tool) is required.
  • roller is a very wear part has a simple contour and is therefore inexpensive to manufacture. Reducing costs It is still the case that the existing toothed rings are used again on new rollers can be.
  • the roller arrangement 1 has a roller shaft 2 which rotates about an axis of rotation D can turn.
  • a roller 3 is attached at one axial end of the roller shaft 2 (in the figure on the right End).
  • the centering of the roller 3 to the roller shaft 2 takes place via a conical centering 9, d. H. about a cone seat, both of them Connects components together.
  • the fixing of the roller 3 on the roller shaft 2 takes place via a screw connection 10, which in the present case is a single screw is formed, the axis of which is identical to the axis of rotation D.
  • the length L of the conical centering 9 extends over a considerable part of the total axial extent L 0 of the roller 3.
  • the length L of the conical centering 9 should be be at least 30% of the axial extent L 0 of the roller 3. This ensures that the bending forces of the roller 3 are absorbed by the roller shaft 2 due to the relatively long taper seat.
  • a drive torque introduced into the roller shaft 2 into the roller 3 can be transmitted safely, are means 4 for the positive transmission of the Driving torque from the roller shaft 2 to the roller 3 is present.
  • This Means 4 consist of two toothed rings 5 and 6. These two toothed rings 5, 6 are trained so that they interact over a variety of Teeth transmit the torque. In the exemplary embodiment there is a splined toothing according to DIN 5480.
  • the first toothed ring 5 is rotatably arranged on the roller shaft 2 during the second toothed ring 6 is rotatably attached to the roller 3.
  • the axis of the pins 7, 8 aligned parallel to the axis of rotation D.
  • a seal 11 is also installed between roller shaft 2 and roller 3.
