摘要： A wind turbine includes a vertically standing non-uniform tower adapted to support a horizontally oriented rotor. A fixed base portion of the turbine is adapted to support a separate rotatable tower having an upper rotor swept portion along the main body of the tower. The tower is adapted to be secured to the base for being rotatably yawed into the wind. A bearing system is housed between the base and lower tower extremity includes a pair of vertically spaced tracks situated on an annular support rail adapted to be fixed to a ground structure, for example a reinforced concrete foundation. The bearing system is further defined by pluralities of yaw bearing cartridge assemblies adapted to extend through flanged apertures of a skirt portion in the lower extremity of the tower.
