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.

A vehicle for transporting heavy loads on parallel tracks is disclosed. Two of the wheels of the vehicle are fixedly mounted to the vehicle frame, while the remaining wheels are mounted so that they can vertically adjust to deviations in the height of the rail track. In this manner, heavy loads can be transported on the rail tracks without any particular wheel becoming overloaded. In the preferred embodiment, the adjustable wheels are supported by bell crank levers which are themselves connected to one another by a parallelogram linkage arrangement.

Force equalizing mechanism for the wheels of heavy load-carrying rail

A tilt drive is provided for a metallurgical vessel which is mounted on a large sprocket wheel driven by two or more reduction gears. The reduction gears are joined by a torque equalizing apparatus which transmits torque from the pinion of one gear to the pinion of the other, thus acting as a forced synchronizer. The torque equalizing apparatus is effective in both the dynamic and static operations of the drive.

Tilt drive for metallurgical vessels

A torque support is provided having a casing supported by a pair of symmetrically arranged steering rods which are pivotally mounted to a pair of upwardly slanted guide rods. The guide rods are pivotally supported on a base member. Inter-connecting the guide rods and the steering rods is a tension-compression rod capable of absorbing tensile and compressive forces. All of the elements of the torque support are provided above floor level. The tension-compression rod is constructed as a plurality of elongated sections, separated from one another by gaps. Located within the elongated sections are compressive spring bundles and a shaft bolt which is secured to supporting surfaces of the elongated sections. In this manner, compressive and tensile forces are cpable of being absorbed by the tension-compression rod.

Torque support

The invention refers to an apparatus for locking a converter tilting gear during a blasting operation, which apparatus is provided with a supplementary gear arrangement to facilitate counterrotation of pinions arranged in pairs versus the pivot pin gear wheel, so that the pinions may be locked and loosened by means of arresting brakes. The arrangement is such that the gear trains for the individual drive pinions can pivot in relation to the position of the pivot pin gear wheel in synchronized fashion to accommodate play between the cooperating gear teeth.
