PROBLEM TO BE SOLVED: To reduce the number of parts, weight, a cost, and assembly man-hours in a wind power generating set, and to make the power generating set more compact. SOLUTION: In the wind power generating set, a windmill 2 converts energy of wind into rotating power to transmit a generator 11 which is directly connected with the windmill 2, and then the generator 11 converts the transmitted rotating power into an electric energy. The generator 11 is constituted of a rotor 12 attached to a main shaft that is a rotation shaft of the windmill, and a stator 13 facing the rotor 12. In the main shaft 10, a portion to which a plurality of blades 3 constituting the windmill 2 are attached, and a portion to which the rotor 12 is attached are integrally formed with the same part and in a tubular shape. The main shaft 10 houses a hydraulic cylinder 34 for changing a pitch angle of the blades 3. COPYRIGHT: (C)2005,JPO&NCIPI |
