Gear Box For Wind Turbine Generator And Supporting Structure For Rotation Shaft

Abstract: 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 (10) for a wind turbine generator which increases a speed of rotation of a wind turbine blade includes a gear (18) to which the rotation of the wind turbine is transmitted, and the gear {18) includes a rotation shaft (19) which is rotatably supported by a first bearing (20) and a second bearing (21) . The first bearing (20) includes a pre-load applying member adapted to partially press the first bearing (20) from outside for increasing contact pressures between an outer ring (22) supported by a casing of the gear box (10), an inner ring (23) mounted on the rotation shaft (19), and rollers (24) provided between the outer ring (22) and the inner ring (23).
