Torque support for absorbing drive torques and roller arrangement with a torque support
A torque support for absorbing drive torques of at least one shaft drive, having two first force-conducting elements, each of which is rotatably fixed to the shaft drive at a distance from one another by a first end, and having a support element arranged at a distance from the shaft drive, to which support element the first force-conducting elements are each fixed rotatably and at a distance from one another by a second end opposite the first end, and spaced apart from one another, and having two second force-conducting elements which are each fixed at a first end to the support element in a rotatable manner and spaced apart from one another and are each fixed at a second end, opposite the first in each case, to a fixed element which is independent of the shaft drive in a rotatable manner and spaced apart from one another. A corresponding roller arrangement is further disclosed.
1. A torque support for absorbing drive torques of at least a first-shaft drive, comprising: two first force-conducting elements, each of which is rotatably fixed to a first end of the first shaft drive at a distance from one another
a support element arranged at a distance from the first shaft drive, the first force-conducting elements are each fixed rotatably to the support element and at a distance from one another by a second end opposite the first,
a fixed element independent of the first shaft drive and
two second force-conducting elements, which are each fixed at a distance from one another by a first end to the support element and are each fixed at a distance from one another by a second end, which is opposite the first end, to the fixed element which is independent of the first shaft drive, wherein the two second force conducting elements are each rotatably fixed with the first end to the support element and are each rotatably fixed with the second end to the fixed element independent of the first shaft drive.
2. The torque support according to claim 1 further comprising a second counter-rotating shaft drive arranged parallel to the first shaft drive, wherein the second ends of the second force-conducting elements are rotatably fixed to the second shaft drive and at a distance from one another.
3. The torque support according to claim 2 , with a second flange surrounding the drive shaft of the second shaft drive, wherein the second ends of the two second force-conducting elements are rotatably fixed opposite to the second flange.
4. The torque support according to claim 2 , wherein a spacer is additionally mounted on the flange of the first or of the second drive, on which the respective ends of the force-conducting elements are fixed, so that the force-conducting elements fixed to the spacer and the force-conducting elements fixed to the drive that the spacer is not mounted on run in planes which differ perpendicularly to an axial direction of the drive shafts.
5. The torque support according to claim 4 , wherein the front force-conducting elements are fixed to the front side and the rear force-conducting elements are fixed to the rear side of the support element.
6. The torque support according to claim 2 , wherein one of the first and one of the second force-conducting elements cross between the fixing points on the first shaft drive and the second shaft drive and the fixing points on the support element.
7. The torque support according to claim 2 , wherein the second ends of the first force-conducting elements and the first ends of the second force-conducting elements are respectively fixed opposite each other and at regular intervals on the support element.
8. The torque support according to claim 1 , wherein the first force-conducting elements and the second force-conducting elements are each rotatably mounted around their respective fixing points.
9. The torque support according to claim 1 , with a first flange surrounding the drive shaft of the first shaft drive, wherein the first ends of the two first force-conducting elements are rotatably fixed opposite each other to the first flange.
10. The torque support according to claim 1 , wherein the the second ends of the first force-conducting elements and the first ends of the second force-conducting elements fixed to the support element are fixed to the support element distributed on a circular circumference.
11. The torque support according to claim 1 , wherein the first force-conducting elements and the second force-conducting elements are arranged parallel to one another.
12. The torque support according to claim 1 , wherein the first force-conducting elements and the second force-conducting elements are rod-shaped.
13. The torque support according to claim 1 , wherein the support element is annular.
14. A roller arrangement with at least two parallel, counter-rotating, rollers, between each of which a nip is formed, wherein the rollers are driven via counter-rotating shaft drives arranged next to one another, having at least one torque support according to claim 1 .
