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 (Fws) 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 (AWS) located in the roll-side interlocking chamber (20), and a second pressure surface (AGS) located in the drive-side interlocking chamber (40), wherein the first and/or the second pressure surface (AWS, AGS) are subjected to the lubrication medium. 3. The rolling mill drive according to claim 2, wherein the first pressure surface (AWS) is smaller than the second pressure chamber surface (AGS). 4. The rolling mill drive according to claim 1, wherein the pressure (PWS) of the lubrication medium in the roll-side interlocking chamber (20) is smaller than the pressure (PGS) 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 (PGS) in the drive-side lubrication medium circuit (60, 62) is greater than the pressure (PWS) 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.
