Abstract
A tilting drive arrangement for a converter has a spur gear wheel fastened to a tilting trunnion of the converter and engaging with at least two pinions driven by a common motor. At least one shaft is provided for a common rotation of the pinions. The pinions are mounted in a carrying gear casing that is overmounted on the trunnion in a position outside the horizontal plane extending through the tilting axis of the converter. A torsionally elastic shaft between the pinions or a pivotally mounted reduction gear on each pinion are provided to produce a uniform torque distribution to the pinions.
Claims7
In a tilting drive arrangement for a converter with a tilting trunnion and a gear casing overmounted on said tilting trunnion, said tilting drive arrangement including a spur gear wheel mounted on said tilting trunnion and surrounded by said gear casing, at least two pinions meshing with said spur gear wheel and arranged within said gear casing in a plane outside the horizontal plane extending through the tilting axis of the converter, shaft means provided for a common rotation of said at least two pinions, a torque support provided to support said gear casing, and a drive motor commonly driving said at least two pinions via said shaft means, the improvement comprising said shaft means including torsionally elastic members, said torsionally elastic members separating the drives to said pinions for providing a uniform torque distribution between the pinions and a balancing of different tooth plays of said pinions.
In a tilting drive arrangement for a converter with a tilting trunnion and a gear casing overmounted on said tilting trunnion, said tilting drive arrangement including a spur gear wheel mounted on said tilting trunnion and surrounded by said gear casing, at least two pinions meshing with said spur gear wheel being arranged within said gear casing in a plane outside of the horizontal plane extending through the tilting axis of the converter, a drive motor being provided to commonly drive said two pinions, shaft means being provided for a common rotation of said at least two pinions and a torque support being provided to support said gear casing, the improvement comprising
- at least two reduction gears, each reduction gear driving one of said at least two pinions and being mounted on said gear casing so as to be pivotable about the respective pinion axis, said at least two reduction gears being motion-coupled to each other;
- at least two bevel gears;
- and
- shaft members of said shaft means being provided for each of said at least two bevel gears, each reduction gear being drive-connected to the drive motor via a shaft member and a bevel gear.
