The present invention relates to a rotorcraft rotor which includes a device for damping lead-lag vibrations of blades (2) of a rotor. The blades (2) are hinged and mounted on a rotating hub (1) of the rotor through each sleeve (3). A damper device includes a set of dampers (6), and each damper is accommodated in each of the sleeves (3) respectively and is transformable between two fixed points (8, 9). One of the two fixed points includes a sleeve and the other includes an engaging member (7) for being engaged with the hub (1) through a link device (10). For each sleeve (3), the damper (6) accommodated by the sleeve (3) is hinged and combined with the link device (10) through a lever arm (11) hinged on the sleeve (3). |
