STEP-UP GEAR DEVICE FOR WIND-DRIVEN ELECTRICITY GENERATION DEVICE, AND WIND-DRIVEN ELECTRICITY GENERATION DEVICE |
摘要 |
The present invention provides a gear box for a wind turbine generator which can reduce damage by flaking even when a self-aligning roller bearing is adopted as a planet bearing and a wind turbine generator. The gear box 14 comprises a casing 40; a carrier 52; a plurality of planet pins 54 supported to the carrier 52; self-aligning roller bearings 56 held on the planet pins 54, respectively; the planet gears 58 supported to the planet pins 54 via the self-aligning roller bearing 56, respectively; and a ring gear 60 and a sun gear 62 meshed with the planet gears 58. The planet gears 58 are fixed to the outer race 56B of the self-aligning bearing 56 with an interference fit, respectively, so that each end surface of the outer race 56B of the self-aligning bearing 56 is positioned inner side to an end surface of each planet gears 58. |
