Title (EN) WIND TURBINE ROTOR
(FR) ROTOR D'ÉOLIENNE
Abstract:
(EN) Wind turbine rotor comprising a hub (10), blades and at least one pitch system for rotating a blade along its longitudinal axis, the pitch system comprising a motor, a drive pinion, an annular gear arranged to mesh with the drive pinion and a pitch bearing that comprises an outer bearing ring, an inner bearing ring and, between these two bearing rings, one or more rows of rolling elements allowing both bearing rings to rotate relative to each other. One of the hub and blade is connected to the inner bearing ring and the other of the hub and blade is connected to the outer bearing ring, and wherein a reinforcing disc (24) is axially fixed to the bearing ring to which the blade is connected at a side facing the hub, the disc being fixed to the bearing ring by the same fasteners connecting the blade to the bearing.
(FR) La présente invention concerne un rotor d'éolienne comprenant un moyeu (10), des pales et au moins un système de pas permettant de mettre en rotation une pale le long de son axe longitudinal, le système de pas comprenant un moteur, un pignon d'entraînement, un engrenage annulaire conçu pour se mettre en prise avec le pignon d'entraînement et une articulation de pas qui comprend une bague de roulement externe, une bague de roulement interne et, entre ces deux bagues de roulement, une ou plusieurs rangées d'éléments roulants supportant des bagues pour se mettre en rotation les uns par rapport aux autres. L'un parmi le moyeu ou la pale est raccordé à la bague de roulement interne et l'autre est raccordé à la bague de roulement externe, et un disque de renforcement (24) étant fixé axialement à la bague de roulement à laquelle la pale est raccordée sur une face opposée au moyeu, le disque étant fixé à la bague de roulement par les mêmes éléments de fixation raccordant la pale au roulement.
