<p><P>PROBLEM TO BE SOLVED: To provide a roller bearing lubricating structure for a planetary gear mechanism, resupplying lubricating oil into a roller bearing even when the supply of the lubricating oil from a hydraulic source to an oil path in the center shaft of a planetary gear is stopped. <P>SOLUTION: To supply lubricating oil into the roller bearing 10 which is arranged between a center hole 5 and the center shaft 6 of the planetary gear 4 of the planetary gear mechanism 1, the oil path 7 is formed in the center shaft 6 in communication with the hydraulic source. A cage 20 of the roller bearing 10 has an oil-bearing member 50 which holds the lubricating oil supplied through the oil path 7 in the center shaft 6 in a releasable manner. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
