gerador de turbina eólica

摘要

Size enlargement of a wind turbine generator is facilitated by eliminating various problems that occur with a bearing that joins a tower (2) and a nacelle. In a wind turbine generator that turnably supports a nacelle installed at the top portion of a tower (2) via a yawing sliding bearing (30), a sliding bearing member (33) of the yawing sliding bearing (30) is provided on at least one of an inner circumferential surface side and an outer circumferential side of the tower (2), and the side-surface length (H) of the sliding bearing member (33) is set to be at least twice the horizontal-direction length (L) of the sliding bearing member.
