<P>PROBLEM TO BE SOLVED: To provide such a structure that large thrust and radial loads caused by wind power applied to a wind turbine are not directly applied to a speed-increasing gear, a worker can enter the inside of the hub of the wind turbine, and maintenance is performed in the inside. <P>SOLUTION: This wind turbine generator with the speed-increasing gear includes the wind turbine and a generator. The speed-increasing gear is composed of a planetary gear only, and is provided on the side of the generator opposite to the wind turbine. A generator shaft is arranged outside on the concentric circle of a main shaft. Both the main shaft and the generator shaft are mutually rotatably integrated by a ball bearing or a roller bearing, and are connected to each other by the planetary gear. <P>COPYRIGHT: (C)2011,JPO&INPIT |
