本文提出差动机构的分类方法,对效率公式和 Bǒge 效率公式的适用范围和局限性作出评价,并采用相对效率、分效率、总效率的概念来分析差动机构的效率计算。在[1]、[2]、[3]、[4]文的基础上运用结构参数变换求相对效率和分效率,以便计算各构件传递的实际功率,作为选择电机和计算零件强度的依据。文中推证了差动机构效率计算的合成原理,将差动机构看成两个并联的分支传动链,应用合成原理计算总效率,从而使分支传动链的效率计算方法可以直接引入差动机构的效率计算中来。这样,差动机构的效率计算就获得了全面的解决。
This paper presents the classification method of differential mechanism, and evaluates the application scope and limitations of the efficiency formula and Bǒge efficiency formula, and uses the concept of relative efficiency, efficiency, and total efficiency to analyze the efficiency calculation of the differential mechanism. Based on the [1], [2], [3] and [4] texts, the relative efficiency and efficiency are calculated by using the structural parameter transformation to calculate the actual power delivered by each component as a basis for selecting the motor and calculating the strength of the component. In this paper, the synthesis principle of the differential mechanism efficiency calculation is deduced. The differential mechanism is regarded as two parallel branch transmission chains. The total efficiency is calculated using the synthesis principle, so that the efficiency calculation method of the branch drive chain can be directly introduced into the differential mechanism. Calculation of efficiency. In this way, the efficiency calculation of the differential mechanism is fully resolved.
