CA 2669050

A wind turbine generator is provided in which damage to a rolling element due to running out of lubricant oil in a main bearing (10) can be reliably prevented even if a wind turbine idles during a power failure. In a wind turbine generator in which the main bearing (10) of a laterally disposed main shaft (6) has an oil supply port (14) and a drain port (15) for lubricant oil, and in which the lubricant oil supplied from an oil pump flows through the oil supply port (14) into the main bearing (10) and flows out through the drain port (15) to circulate, the drain port (15) is disposed above the center of a lower rolling element disposed in the main bearing (10).

Générateur éolien dans lequel, même si une turbine tourne à vide durant une panne d'alimentation électrique, on évite efficacement d'endommager les corps roulants à cause du manque de lubrifiant au niveau de la section de palier principal (10). Dans ce générateur éolien, la section de palier principal (10) de l'arbre principal (6) placé dans la direction latérale présente une ouverture pour l'alimentation en huile (14) et une ouverture de vidange (15) du lubrifiant. Le lubrifiant transféré depuis une pompe d'alimentation en huile circule dans la section de palier principal (10) depuis l'ouverture d'alimentation en huile (14) et hors de l'ouverture de vidange (15) pour être recyclé. L'ouverture de vidange (15) est placée au-dessus du centre des corps roulants inférieurs montés dans la partie palier principal (10).
