| 摘要 |
The present invention relates to a planetary gear equipped with a lubricating structure, in which a lubricant supply/discharge path is formed in a carrier to supply a lubricant to a pinion shaft. A planetary gear equipped with the lubricating structure according to an embodiment of the present invention comprises an input shaft; a sun gear disposed on the input shaft to form a first lubricant supply path between the input shaft and the sun gear, and having a discharge path of the lubricant which penetrates a portion of the surface; a carrier disposed on the sun gear to form a second lubricant supply path; a pinion shaft meshed with the carrier to form a third lubricant supply path to which the lubricant flowing through the second lubricant supply path of the carrier is supplied; and a needle bearing disposed between the pinion shaft and the pinion gear and provided with the lubricant from the third lubricant supply path of the pinion shaft. |
