    摘要： It is an object to provide a gear box for a wind turbine generator and a rotation-shaft supporting structure which are capable of suppressing the occurrence of slips in a bearing with lower costs. A gear box for a wind turbine generator which increases a speed of rotation of a wind turbine blade includes a gear to which the rotation of the wind turbine is transmitted, and the gear includes a rotation shaft which is rotatably supported by a first bearing and a second bearing. The first bearing includes a pre-load applying member adapted to partially press the first bearing from outside for increasing contact pressures between an outer ring supported by a casing of the gear box, an inner ring mounted on the rotation shaft, and rollers provided between the outer ring and the inner ring.

    摘要： 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 shaft 11, a gear-box for speeding up rotation of the main shaft 11 and a generator 13 driven by an output of the gear-box 11 are provided on a nacelle bed plate 6. The main shaft 11 is connected to an input shaft 12a end of the gear-box 12 via a double-row tapered roller bearing 16. The main shaft 11 is supported to a wall portion W1 of the nacelle bed plate 6 with the double-row tapered roller bearing 16 being interposed therebetween. The main shaft 11 is formed in an annular shape having its outer diameter D1 larger than its axial directional length L1.
