<P>PROBLEM TO BE SOLVED: To provide a planetary gear lubricating device for sufficiently supplying lubricating oil to a bearing area nearer the center of revolution independently of the vertical/horizontal direction of a reduction gear. <P>SOLUTION: The planetary gear lubricating device includes a rolling bearing 19 laid between a planetary gear 15 and its supporting shaft 16, and an oil supply means for supplying lubricating oil from the side of the supporting shaft 16 to the rolling bearing 19. The oil supply means consists of a supplied oil reservoir 25 provided in one end face of the supporting shaft 16 in an axially opened manner, and an oil supply nozzle 30 installed outside the bearing in axial opposition to the supplied oil reservoir 25. The supplied oil reservoir 25 includes a shaft side oil supply hole 26 communicated with its peripheral wall 24 on the side of the rolling bearing 19, and partition walls 28, 29 for guiding the lubricating oil to the shaft side oil supply hole 26 with centrifugal force. <P>COPYRIGHT: (C)2011,JPO&INPIT |
