Title:
風力タービンのための駆動組立体
Document Type and Number:
Japanese Patent JP2004506845
Kind Code:
A
Abstract:
A drive assembly for a wind turbine includes a rotor hub, a supporting structure, a planetary gear transmission unit having sun, planet and ring gears and a planet carrier. The ring gear is non-rotatably secured to the supporting structure. A main bearing rotatably supports the rotor hub and planet carrier relative to the ring gear and supporting structure. The drive assembly further includes two substantially independent force transmission paths for transmission of forces reacting with forces exerted by the wind turbine rotor hub. A first of the force transmission paths acts from the rotor hub via the main bearing to the supporting structure primarily for transmission of overhang load forces and bending moment forces and a second of the force transmission paths acts from the rotor hub via the planet carrier primarily for transmission of rotational forces.
