Definitions

  • the invention relates to a device for axial displacement of rollers that are in, in the bearing chocks of the rolling stand Axial and radial bearings arranged coaxially one behind the other are stored, with an annular piston that can be pressurized with pressure medium, the circumference of one connected to the housing of the thrust bearing Carrier is arranged.
  • the setting and compliance with a certain axial position of cooperating rollers is respecting the, in particular arise when rolling asymmetrical profiles in the roll caliber Axial forces for the rolling accuracy and straight running of the Rolling stock of importance.
  • This also applies to the horizontal rolls of a universal roll stand because of a possible relative axial displacement between the horizontal rolls the tolerances of the Flange thickness can be adversely affected by parallel flange supports can.
  • good tolerance tolerance of the flange thickness is required.
  • it can be moved transversely to the rolling line Caliber cartridges, the two or more optionally in the rolling position have feasible so-called election calibers, attitude and compliance the relative axial position of the co-operating rollers required.
  • the invention has for its object these devices to improve the axial displacement of the rollers so that at a structurally simplified construction the disadvantages of the large mentioned Overall length and the effort involved in assembling and disassembling the bearing be avoided.
  • the annular piston Section of the bearing housing in a seated in the bearing chock Cylinder liner slidably arranged and against it with ring seals be sealed.
  • the cylinder liner can be used for simplification the installation and removal of the bearing housing radially divided be trained.
  • the invention is based on the embodiment shown in the drawing explained in more detail.
  • the thrust bearing 5 consisting of the two inner bearing rings 5a, the bearing rollers 5b and the two outer Bearing rings 5c.
  • the outer bearing rings 5c are from the bearing housing 6 comprises, here from three, by a screw 7th held together housing parts 6a, 6b, 6c.
  • the thrust bearing 5 comprehensive peripheral portion of the bearing housing 6 has the Form of an annular piston RK on an annular cylindrical recess 8a of a cylinder liner 8 is included, which in the 9th indicated bearing chock sits.
  • the between the radial Side surfaces of the ring-cylindrical recess 8a and this opposite annular surfaces of the annular piston RK formed annular gaps are above the pressure medium supply lines indicated by dashed lines 10 in connection with the pressure medium control, not shown.
  • the RK ring piston and with it via the bearing housing 6 and the radial bearing 5 of the roll neck 1 can control this pressure medium and a linear encoder in the desired way be positioned.
  • the cylinder liner 8 is split here and the ring piston RK sealed against them with ring seals.
