【摘要】 介绍了一种新型对称加载行星牵引传动减速器，它保留了行星齿轮传动比大的优点．由于它采用３组行星轮与２个锥面钢套对称加载，利用牵引油拖动，工作面多，传动效率高；接触处采用共曲面，接触应力下降；与齿轮传动相比结构简单，制造安装方便，噪声小，特别具有不受行星齿轮传动齿数安装条件限制的优点更多还原

【Abstract】 A new symmetrically loading epicyclic traction drive reducer is introduced. It has advantage of high drive ratio of other epicyclic gears. It loads three epicyclic gears and two steel tapers and drives through traction oil. It has more work surfaces and higher drive ratio. Its contact stress is decreased because the same curved surfaces is used at the contact region. It has simpler structure, easier making and installation,lower noise than ordinary gear drive. Especially, unlike ordinary epicyclic gear, its installation will not be limited by the number of gears.更多还原
