Rotor for a wind turbine

摘要

The invention relates to a rotor for a wind turbine of the type having a rotor hub (8) and a set of rotor blades (9). Each rotor blade (9) is rotatably mounted on the rotor hub (8) for rotation about a blade axis (11). A threaded spindle mechanism (13) interconnects the rotor blade (9) and the rotor hub (8). The threaded spindle mechanism (13) includes a spindle nut (32), a threaded spindle (31) and a drive (21) mounted on the rotor blade (9) adjacent a transition between the rotor hub (8) and the rotor blade (9). The drive (21) is rotatable together with the rotor blade (9) about the blade axis (11) relative to the rotor hub (8) by actuation of the threaded spindle mechanism (13).

主权项

1. A rotor for a wind turbine comprising:
a rotor hub; at least one rotor blade mounted on the rotor hub and rotatable about a blade axis; and a blade angle adjustment drive having:
a threaded spindle mechanism;a motor forming a drive and having an output shaft; anda transmission operably coupled to the output shaft of the motor;the threaded spindle mechanism interconnecting the rotor hub and one of the at least one rotor blade, the threaded spindle mechanism including a spindle nut, a threaded spindle and the drive, and wherein the drive and the transmission are both mounted on the rotor blade adjacent a transition between the rotor hub and the rotor blade, the drive and the transmission being configured to drive the threaded spindle rotationally, and the drive and the transmission further being rotatable together with the rotor blade about the blade axis, wherein the at least one rotor blade is rotatable about the blade axis relative to the rotor hub by actuation of the threaded spindle mechanism.
