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必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。
Previously, closed-loop planetary gear power flow analysis and calculation of engagement efficiency is difficult and complicated thing. Based on the fact that two of the three basic components of the differential gear train will be the same as the active part or the driven part, three new efficiency formulas are deduced. According to the efficiency should be less than 1 and the two main components Status of the same conditions, you can determine the conversion mechanism meshing power flow. The above mentioned problems are easily solved by summarizing and tabulating the mathematical expressions reflecting the objective laws of differential gear train in terms of energy transfer.
