ABSTRACT:
A torque support for drives riding on trunnions, in particular for converter tilt drives, including a gear housing mounted on the trunnion which is rotatable about an axis of rotation, a drive motor attached by a flange or bolting to a step-down gearing which engages, via pinion, with a larger gear wheel fixed for rotation on the trunnion. The torque support includes a pair of guide rods located symmetrically to the axis of rotation of the trunnion, each guide rod includes a first and second oppositely positioned part, the first and second rod part have an upper and lower end and a respective free end opposite thereto; the upper ends are pivotally mounted on the gear housing and the lower ends are connected to each other via either a compression-tension bar or torsion shaft, upon which the lower ends are pivotally mounted. A spring element which connects the free ends of the first and second guide rod parts in spaced relation from the mounts acts in tension and compression and includes springs and a mechanism for predeterminately pre-stressing the springs.
