  • Vibration damping system by means of a hydraulic actuation system
    Patent number: 9599131
    Abstract: 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).

  • Vibration damping system for a rolling mill with first and second passive hydraulic elements
    Patent number: 9211576
    Abstract: The present application relates to a vibration damping system for a rolling mill comprising a rolling cage and a bending adjustment system (3,3?) of the rollers comprising hydraulic actuators acting on the rollers and hydraulic circuits (18, 19) for feeding, and hydraulic damping means (25, 31, 32) of a force connected to the hydraulic circuits (18, 19) for actuating a damping effect by means of the hydraulic actuators. The hydraulic damping means comprises a pair of hydraulic pumps (25B, 25C) or a pair of hydraulic cylinders with a dual chamber, connected in an opposite direction to each other to the hydraulic circuits (18, 19).
