Abstract

Das Verfahren zum Antrieb von drehbaren Maschinenteilen, insbesondere Walzen von Walzstraßen, arbeitet mit Hydro­ motoren (1), deren Schwenkwinkel durch ein Stellglied (2) zur Veränderung des Schluckvolumens und damit des übertragbaren Momentes verstellt wird. Zusätzlich ist eine Drossel (4) in die Fluidzufuhr eingeschaltet, deren Öffnungsquerschnitt veränderlich ist. Die Regelung erfolgt derart, daß vor dem Auftreten eines Lastmomentes in von der Drehzahlregelung entkoppelter Verstellbewegung der Schwenkwinkel zur Über­ tragung eines vorgegebenen Drehmomentes verstellt wird, wobei die Drehzahlregelung ausschließlich durch Änderung der Energiezufuhr zum Hydromotor erfolgt, worauf für die Aufrechterhaltung der Arbeitsdrehzahl nach Auftreten eines Lastmomentes die Drehzahlregelung unter Einbeziehung der Stellvorrichtung für die Verstellung, insbesondere der Winkelverstellung, des Hydromotors in die Drehzahlregelung erfolgt. The process for driving rotating machine parts, especially rolling of rolling mills, works with Hydro motors (1), the swivel angle by an actuator (2) for Change in the swallowing volume and thus the transferable Moment is adjusted. In addition, a throttle (4) is in the fluid supply switched on, the opening cross section is changeable. The scheme is such that before Occurrence of a load torque in from the speed control decoupled adjustment movement of the swivel angle to the over Adjustment of a predetermined torque is adjusted, wherein the speed control only by changing the Energy is supplied to the hydraulic motor, which is followed by the Maintaining the working speed after the occurrence of a Load torque the speed control including the Adjustment device for the adjustment, in particular the Angle adjustment of the hydraulic motor in the speed control he follows.
