Abstract
(EN) The invention concerns a transmission mounted in a housing between a turbine and a generator on top of a tower of a wind turbine, comprising a gearbox and in the gearbox a main gear mounted on a main gear shaft and a pinion that engages a set of gear teeth of the main gear. The pinion is mounted on a pinion shaft and the pinion shaft is coupled to a hydraulic pump mounted on the gearbox, a hydraulic motor drives the generator. In accordance with the invention the main gear shaft and the rotor shaft together form a common shaft and a main gear shaft bearing is mounted between the common shaft and the gearbox and at least two tension bars prevent the rotation of the gearbox and leave the gearbox free to move in linear directions.
(FR) L'invention porte sur une transmission montée dans un carter entre une turbine et une génératrice au sommet d'une tour d'une turbine éolienne. Cette transmission comprend une boîte de vitesses et, dans la boîte de vitesses, un pignon principal monté sur un arbre de pignon principal et un pignon qui engrène un jeu de dents d'engrenage du pignon principal. Le pignon est monté sur un arbre de pignon et l'arbre de pignon est accouplé à une pompe hydraulique montée sur la boîte de vitesses. Un moteur hydraulique entraîne la génératrice. Selon l'invention, l'arbre de pignon principal et l'arbre de rotor forment ensemble un arbre commun, et un palier d'arbre de pignon principal est monté entre l'arbre commun et la boîte de vitesses, et au moins deux barres de tension empêchent la rotation de la boîte de vitesses et laissent la boîte de vitesses libre de se déplacer dans des directions linéaires.
