Abstract

The invention relates to a rotor for a wind turbine (1), comprising a rotor hub (8), at least one rotor blade (9), which is supported on the rotor hub (8) so as be rotatable about a blade axis (11), at least one threaded spindle mechanism (13), which is inserted between the rotor hub (8) and the rotor blade (9) and which is connected both to the rotor hub (8) and to the rotor blade (9), wherein the rotor blade (9) is or can be rotated about the blade axis (11) relative to the rotor hub (8) by actuation of the threaded spindle mechanism (13), and wherein the threaded spindle mechanism (13) comprises a drive (22), a gear train (23), a spindle nut (18), and a threaded spindle (19) which is arranged outside the drive (22) and which is coupled with said drive through the gear train (23).
