VIBRATION DAMPING SYSTEM BY MEANS OF A HYDRAULIC ACTUATION SYSTEM |
摘要 |
A vibration damping system by means of a hydraulic actuation system, in particular for rolling mills, comprising at least one hydraulic actuator (1) having a movable part (11) and a corresponding hydraulic feeding circuit (2), and hydraulic damping means (3) for a vibrating force acting on the movable part (11) of the hydraulic actuator (1); the damping means (3) being connected to the hydraulic circuit (2) to actuate a damping of the vibrating force, wherein that the damping means (3) comprise a double chamber cylinder (31) having a first chamber (34) hydraulically connected to the hydraulic circuit (2), and a movable part (35) connected to an electric damping part (32), with the first chamber (34) hydraulically connected to and communicating with the second chamber (33) of the double chamber cylinder (31) by means of a calibrated pipe (36). |
