Wind Turbine Generator

Abstract: A wind-driven generator whose yaw system (10A) installed at the upper part of a support (2) is reduced in the number of its components and weight. The wind-driven generator has the yaw system (10A) equipped with a yaw driving device (30), a yaw slewing ring, and a yaw brake and slewing a nacelle installed at the upper part of the support (2) according to the direction of the wind. A yaw slewing ring fixed to a nacelle table plate (12) through a bracket (23A) having a nearly L-shaped cross section functions as the slide bearing (20A). Thus, the slide bearing (20A) slidably supports a flange part (2a) formed at the upper end of the support (2) with slide pads (22) held by the bracket (23A).
