Abstract

The invention relates to a rolling mill drive ( 1 ) having an axially displaceable toothed articulated spindle ( 3 ) extending between a toothed articulated element ( 50 arranged between an interlocking chamber ( 20 ) on the roller side and a toothed articulated element ( 52 ) arranged in an interlocking chamber ( 40 ) on the transmission side, wherein at least one of the interlocking chambers ( 20, 40 ) is filled with a lubricating medium, wherein the lubricating medium biases the toothed articulated spindle ( 3 ) with an axial force (F ws ) directed towards the roll side (WS).

First claim

The invention claimed is:

1. A rolling mill drive ( 1 ), comprising an axially displaceable toothed articulated spindle ( 3 ) extending between a toothed articulated element ( 50 ) located in a roll-side interlocking chamber ( 20 ) and a toothed articulated element ( 52 ) located in a drive-side interlocking chamber ( 40 ), wherein at least one of the interlocking chambers ( 20 , 40 ) is filled with a lubrication medium, characterized in that
the lubrication medium biases the toothed articulated spindle ( 3 ) with an axial force (F ws ) acting in a direction of the roll side.

2. The rolling mill drive according to claim 1 , wherein the toothed articulated spindle ( 3 ) has a first pressure surface (A WS ) located in the roll-side interlocking chamber ( 20 ), and a second pressure surface (A GS ) located in the drive-side interlocking chamber ( 40 ), wherein the first and/or the second pressure surface (A WS , A GS ) are subjected to the lubrication medium.

3. The rolling mill drive according to claim 2 , wherein the first pressure surface (A WS ) is smaller than the second pressure chamber surface (A GS ).

4. The rolling mill drive according to claim 1 , wherein the pressure (P WS ) of the lubrication medium in the roll-side interlocking chamber ( 20 ) is smaller than the pressure (P GS ) of the lubrication medium in the drive-side interlocking chamber ( 40 ).

5. The rolling mill drive according to claim 1 , wherein at least the drive-side interlocking chamber ( 40 ) for the lubrication medium is formed to be pressure-tight.

6. The rolling mill drive according to claim 1 , wherein at least one drive-side lubrication medium circuit ( 60 , 62 ) for supplying the drive-side interlocking chamber ( 40 ) with lubrication medium and at least one roll-side lubrication medium circuit ( 60 , 62 ) for supplying the drive-side interlocking chamber ( 20 ) with lubrication medium are provided.

7. The rolling mill drive according to claim 6 , wherein the pressure (P GS ) in the drive-side lubrication medium circuit ( 60 , 62 ) is greater than the pressure (P WS ) in the roll-side lubrication medium circuit ( 64 , 66 ).

8. The rolling mill drive according to claim 6 wherein the drive-side lubrication medium circuit ( 60 , 62 ) and/or the roll-side lubrication medium circuit ( 64 , 66 ) at least partially extend in the toothed articulated spindle ( 3 ).

9. The rolling mill drive according to claim 8 , wherein a rotary feeder ( 6 ) for supplying at least one of the lubrication medium circuit ( 60 , 62 ; 64 , 66 ) with the lubrication medium is provided on the toothed articulated spindle ( 3 ).

10. The rolling mill drive according to claim 8 , wherein a rotary feeder ( 6 ) for supplying at least one of the lubrication medium circuits ( 60 , 62 ; 64 , 66 ) is provided on a drive sleeve ( 4 ).

11. The rolling mill drive according to claim 1 , wherein the lubrication medium remains stationary in at least one interlocking chamber ( 20 , 40 ).

12. The rolling mill drive according to claim 1 , wherein the drive-side interlocking chamber ( 40 ) is so formed that it enables axial displacement of the toothed articulated spindle ( 3 ).

13. The rolling mill drive according to claim 1 , wherein a circulation lubrication with the lubrication medium is provided for.
