| 摘要 | PURPOSE:To enable stable formation of oil film by etching a spiral oil groove in large diameter planetary roller and moving lubricant along said groove. CONSTITUTION:Large diameter section 23 for positioning the small diameter section 22 between the large diameter section 21 is provided on a planetary roller 2 while spiral oil grooves 5, 5 are made in the outercircumferential faces of the large diameter sections 21, 23. Upon rotation of the planetary roller 2, lubricant in said grooves 5, 5 will move along the groove 5 to be fed to the contacting section between the large diameter sections 21, 23 and the rotary shaft 1 and between the large diameter section 21 and the outer ring 11. Consequently, the lubricant can be circulated well during operation thus to never break the oil film. | ||||||
