DISPOSITIF POUR REDUIRE LES VIBRATIONS ENGENDREES PAR UN ROTOR DE SUSTENTATION D'UN GIRAVION, ET MOYEU D'UN ROTOR MUNI D'UN TEL DISPOSITIF.

摘要

The device (10) has a support (20) and a weight element (30) that is fastened to the support by a connection unit (40). The weight element is connected to the connection unit by a guide unit (50) for guiding the weight element in circular translation movement in a filter plane (P1) that is movable perpendicular to an elevation axis (AX) of the device. The connection unit includes resilient return units (41) that allow the filter plane to move in elevation while maintaining the filter plane perpendicular to the elevation axis under an effect of vibration.
