    摘要: In an object to provide a gear box for a wind turbine generator and a wind turbine generator in which the life of the planet bearings are further enhanced, a gear box of the present invention includes a casing, a carrier, planet pins held to the carrier, planet bearings supported to the planet pins, respectively, a plurality of planet gears supported to the planet pin via the planet bearings, respectively, and a ring gear and a sun gear meshed with the planet gears. In the gear box, the carrier has an inclined surface facing the planet bearing as a part of an outer cylinder part provided on both ends of the planet pins in axial direction of the planet pin and surrounding the outer circumference of the both ends of the planet pins and the incline surface inclines such that the farther from an axial center of the planet pin, the longer a distance between the inclined surface and the planet bearing.

    摘要: A wind turbine generator including a nacelle having reduced size and weight is provided. The wind turbine generator includes a nacelle disposed on a tower. The nacelle includes a main shaft that is connected to a rotor head equipped with blades and that integrally rotates with the rotor head, a gearbox that increases the rotational speed of the main shaft and that outputs the resulting rotational speed, and a generator driven by the output from the gearbox. In the wind turbine generator, a drivetrain extending from the main shaft to the generator via the gearbox is disposed in the rotor head.
