| 摘 要： | 此前，封闭式行星传动的功率流向分析和啮合效率计算是使人感到既难又繁的事，本文根据差动轮系的三个基本构件中心有两个将同为主动件或从动件这一特点，推导出三个新的效率公式，并根据效率应小于1及两基本构件主从地位相同的条件，便可确定转化机构中啮合功率的流向，将这些反映差动轮系在能量传递方面客观规律的数学式汇总并以表格的形式列出，很方便地解决了上述问题。

| Abstract: | It used to be quite difficult and complicated to analyze the power flow of closed differential gear train and to compute its efficiency. In this paper it is pointed out that based on the characteristic that two of three basic links in a differential gear train are either driver or driven, three new efficiency formulas were easily obtained; and based on the knowledge that efficiency is numerically less than one and on the condition that two basic links are in the same driving or driven position, the direction of the power flow was conveniently determined in the fixed carrier train; and the formulas that reflect the objective law of differential gear train in delivering energy have been summarized and put into tables, thus suggesting an easy solution to the above problems. |
