摘　　要：齿轮的基本啮合效率是计算行星齿轮传动效率的基础.指出了齿轮传动在升速和减速时基本啮合效率不相等,升速时比减速时要高,这不同于以往的观点.为论证此结论,采用了一种新方法,分析了内啮合、外啮合直齿轮和斜齿轮传动的基本啮合效率,推导了它们在升速和减速两种状态时,基本啮合效率精确的计算公式,并以2K-H行星齿轮传动为例进行了分析.Reference efficiency of a pair of gear drive without planetary motion is the base to calculate efficiency of the whole planetary gear train. The authors find reference efficiency for speed increase is higher than that of the same drive used for speed reduction. This is different from the earlier viewpoint. New equations are derived for correctly calculating the reference efficiency of spur gear and helical gear with internal conjugate and external conjugate either in the state of speed increase or speed reduction respectively. The equations are also used to calculate efficiency of 2K-H planetary gear train.
