Title (EN) A WIND TURBINE, A HUB FOR A WIND TURBINE AND USE HEREOF
(FR) EOLIENNE, MOYEU D'EOLIENNE ET UTILISATION
Abstract:
(EN) The invention relates to a wind turbine (1) comprising at least two blade units (31). Each blade unit (31) comprises a pitch controlled wind turbine blade (5) and at least one pitch bearing (9) including at least one outer ring (24), at least one center ring (25) and at least one inner ring (26). The wind turbine (1) further include a hub (7) comprising a mount area (6) for each of the blade units (31). This wind turbine (1) is characterized in that the mount area (6) comprise at least two concentric load tranferring surfaces (10, 11) for attaching the blade unit (31), via the at least one pitch bearing (9). The invention further relates a hub and a use hereof.
(FR) Eolienne (1) à au moins deux unités de pale (31), chacune comprenant une pale à contrôle de pas (5) et au moins un roulement de pas (9) avec au moins un anneau externe (24), au moins un anneau central (25) et au moins un anneau interne (26). L'éolienne (1) comprend en outre un moyeu (7) à surface de montage (6) correspondant à chaque unité de pale (31). L'éolienne (1) est caractérisée en ce que la surface de montage (6) comprend au moins deux surfaces concentriques de transfert de charge (10, 11) pour al fixation de l'unité de pale (31), via le ou les roulements de pas (9). L'invention concerne par ailleurs un moyeu et une utilisation correspondante.
