<P>PROBLEM TO BE SOLVED: To provide a compact, lightweight and low-cost speed increasing gearbox for wind power generation configured to achieve high reliability and long lifetime. <P>SOLUTION: The speed increasing gearbox 50 for wind power generation includes a planetary gear mechanism 52. The speed increasing gearbox 50 includes a planetary gear 68 constituting one element of the planetary gear mechanism 52, and a carrier 62 that rotatably supports the planetary gear 68 via a roller bearing 76. A plurality of ring-shaped members 88A-88E are interposed between the planetary gear 68 and the roller bearing 76. On the inner and outer circumferential sides of the ring-shaped members 88A-88E, gaps S1, S2 are formed, respectively, where lubricant enters. <P>COPYRIGHT: (C)2013,JPO&INPIT |
