复杂复合轮系效率计算的新方法

A New Solution of Efficiency Calculation for Complex Epicyclical Gear Trains

目前 ,有些复杂的复合轮系很难用效率公式来计算效率 ,故本文首先将轮系分解成几个简单的基本轮系单元 ,然后对轮系进行运动分析和力矩分析 ,列出线性方程组并求解 ,不仅能求出效率 ,而且每个构件的角速度及所受力矩皆已求出 ,整个轮系的功率流向也随之确定了 ,这也便于设计者对轮系进行分析、改型及强度计算。

It is still very difficult at present to calculate the efficiency of some of the complex epicyclical gear trains with the efficiency formulas So in this paper the complicated epicyclical gear train is, first of all, decomposed into simple fundamental elements; then these elements are put into kinematics analysis and moment analysis, and finally the linear equations are listed and solved In this way not only the efficiency but also the angle speed of each component and the moment it bears are extracted, and also it would be much more convenient to determine the power flow of the whole train, and easier for designers to analyze and improve the gear train and to calculate the strength
