Claims
- 1. A sealing arrangement between relatively rotatable components, comprising:
a first component comprising a cylindrical circumferential surface on one of an interior and exterior circumference; a second component comprising a ring groove open toward said circumferential surface; a ring-shaped carrier being arranged to be displaceable in said ring groove; a centering rod arranged to guide said ring-shaped carrier on said circumferential surface; a radial lip seal arranged to rest against said circumferential surface in an elastic manner; an axial seal arranged to rest against a side wall of said ring groove; and an anti-twisting device coupled to said ring-shaped carrier and arranged to enable a limited range of motion in all directions of a radial plane.
- 2. The arrangement in accordance with claim 1, wherein said anti-twisting device comprises a ring disk with recesses and stops arranged to jut laterally from said carrier and to protrude into said recesses.
- 3. The arrangement in accordance with claim 2, wherein said recesses have a larger cross sectional area than that of said stops.
- 4. The arrangement in accordance with claim 2, wherein said stops and said recesses have circular shapes.
- 5. The arrangement in accordance with claim 4, wherein a diameter of said recesses is about 2.5-3 times a diameter of said stops.
- 6. The arrangement in accordance with claim 2, wherein said stops comprise heads of bolts which are axially inserted into said ring-shaped carrier.
- 7. The arrangement in accordance with claim 6, wherein said bolts are arranged to hold said radial lip seal against said carrier.
- 8. The arrangement in accordance with claim 6, further comprising a circular support disk supporting said radial lip seal and which is fixedly coupled to said carrier via said bolts.
- 9. The arrangement in accordance with claim 2, wherein said anti-twisting device comprises an anti-twisting ring disk which includes said recesses, said anti-twisting ring disk being located concentrically within said ring groove.
- 10. The arrangement in accordance with claim 9, wherein said anti-twisting device further comprises a circular covering disk arranged to coupled said anti-twisting ring disk to said second component via axial screws.
- 11. The arrangement in accordance with claim 1, wherein a radial lip of said radial lip seal is loaded by a spring in a direction of said circumferential surface.
- 12. The arrangement in accordance with claim 11, wherein said spring comprises a circular plate spring having a U-shaped cross section.
- 13. The arrangement in accordance with claim 1, wherein one of said first and said second component has a rotationally fixed axis and the other of said first and said second component supports a jacket of a sagging compensation roll.
- 14. The arrangement in accordance with claim 13, wherein said sagging compensation roll is hydraulically supported on said other component.
- 15. An apparatus for providing a seal between relatively rotatable components, comprising:
a first component comprising a cylindrical circumferential surface on one of an interior and exterior circumference; and a second component comprising a ring groove open toward said circumferential surface; a ring-shaped carrier being arranged to be displaceable in said ring groove; a radial lip seal being arranged to rest against said circumferential surface in an elastic manner; and an anti-twisting device coupled to said ring-shaped carrier and arranged to enable a limited range of motion in all directions of a radial plane.
- 16. The apparatus in accordance with claim 15, wherein said anti-twist device is coupled to said ring groove and comprises an anti-twist ring disk having recesses.
- 17. The apparatus in accordance with claim 16, wherein stop devices are arranged to extend from said ring-shaped carrier and into said recesses.
- 18. The apparatus in accordance with claim 17, wherein said radial lip seal is coupled to said ring-shaped carrier by bolts, and wherein heads of said bolt form said stop devices.
- 19. The apparatus in accordance with claim 18, further comprising a supporting ring disk arranged to support said radial lip seal, and located between said radial lip seal and said anti-twist ring disk.
- 20. The apparatus in accordance with claim 21, wherein said bolt heads extend from said supporting ring disk.
- 21. The apparatus in accordance with claim 17, wherein said recesses have a greater cross sectional area than said stop devices.
- 22. The apparatus in accordance with claim 17, further comprising an axial seal arranged between said ring groove and said ring-shaped carrier.
- 23. The apparatus in accordance with claim 17, further comprising a centering rod arranged to guide said ring-shaped carrier on said circumferential surface.
