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.
