Abstract

See full text

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).
