Abstract
A method and an arrangement for operating a rotating starting shear operating in a start-stop operation on rolling stock travelling at different speeds in wire mills, light-section mills, medium plate mills and billet mills, wherein the shear, whose gear system is connected through a coupling to a drive motor, is accelerated from the position of rest to approximately rolling speed and, after the cut has been carried out, is stopped again. A gear machine is arranged between the gear unit of the shear and the drive motor, wherein torsion-proof couplings are arranged between the gear unit or the shear and the gear mechanism and between the gear mechanism and the drive motor.

An arrangement for operating a rotating starting shear operated in a start-stop operation on rolling stock travelling at different speeds in a rolling mill, wherein the shear comprises shear knives, a gear unit and a drive motor coupled to the gear unit, wherein the shear is accelerated from a position of rest to approximately the speed of the rolling stock and, after a cut has been carried out, the shear is stopped again, further comprising a gear mechanism arranged between the gear unit and the drive motor of the shear, and a first torsion-proof coupling connecting the gear unit and the gear mechanism and a second torsion-proof coupling for connecting the gear mechanism and the drive motor.
