The invention concerns a device comprising a nacelle (3) mounted rotating about a vertical axis on the upper part of a mast (2) and comprising a rotating part (10) mounted rotating about a substantially horizontal axis via a bearing (15) with large diameter. The rotating part (10) comprises a hub (13) whereon are mounted blades (14). The device comprises an electric generator (12) having a stator (17) and a discoid rotor (16). The rotor (16) is secured by a linking element (20) on the hub (13), in a location adjacent to the bearing (15), such that the forces exerted by the wind on the rotating part (10) are transmitted directly to the bearing (15) without passing through the electric generator (12).
Le dispositif comporte une nacelle (3) montée rotative autour d'un axe vertical sur la partie supérieure d'un mât (2) et comportant une partie tournante (10) montée rotative autour d'un axe sensiblement horizontal par l'intermédiaire d'un palier (15) de grand diamètre. La partie tournante (10) comporte un moyeu (13) sur lequel sont fixées des pales (14). Le dispositif comporte une génératrice électrique (12) ayant un stator (17) et un rotor (16) de forme discoïde. Le rotor (16) est fixé par un élément de liaison (20) sur le moyeu (13), dans une disposition adjacente au palier (15), de sorte que les efforts exercés par le vent sur la partie tournante (10) sont transmis directement au palier (15) sans transiter par la génératrice électrique (12).
