ABSTRACT:
A power generating wind turbine includes parts and components installed in or on a nacelle which are made smaller and lighter, thus facilitating maintenance. A main shaft11, a gear-box for speeding up rotation of the main shaft11and a generator13driven by an output of the gear-box11are provided on a nacelle bed plate6. The main shaft11is connected to an input shaft12aend of the gear-box12via a double-row tapered roller bearing16. The main shaft11is supported to a wall portion W1of the nacelle bed plate6with the double-row tapered roller bearing16being interposed therebetween. The main shaft11is formed in an annular shape having its outer diameter D1larger than its axial directional length L1.
