<P>PROBLEM TO BE SOLVED: To provide a reduction gear with an output pinion for a wind generation system in which the device is installed while the device is configured such that the output shaft is supported at its side-by-side, and almost the output pinion can be covered to protect. <P>SOLUTION: A reduction gear G1 with an output pinion for a wind generation system, in which the output shaft 32 is supported side-by-side by a pair of ball bearings of the self-aligning ball bearing 70 and the ball bearing 72, wherein both of the pair of bearings 70, 72 are contained in the output side casing 74 integrally molded by a single member including the cover part 74A of the anti-drive source side of the output shaft 32. The self-aligning ball bearing 70 is supported by the output side casing 74 via the bearing housing 76 which is different from the output side casing 74, and the output side casing 74 has the opening 74C formed at the electric motor side such that the diameter thereof is larger than the outer diameter d1 of the output pinion 24, and the engagement window 74D for the output pinion 24 with the rotating internal tooth gear (ring gear). <P>COPYRIGHT: (C)2010,JPO&INPIT |
