摘要

提出了一种展示结构与功率流特性关系的图解分析模型，对可能存在的结构型式与效率进行了探究。研究表明，循环功率的存在与否由结构本身决定，与结构中特性参数,P,无关；提出了6种传动比范围较大的结构型式；结合分析模型对传动比和效率的关系进行了探讨，得知在特性参数,P,∈[3，8]条件下必然存在循环功率的传动比区间。最后，结合该方法对某方案进行效率分析，以改变齿比的方式提升了效率。

Abstract

A graphical analysis model is proposed to explore the possible structural patterns and efficiency. The research shows that the existence of cycle power is determined by the structure itself and has nothing to do with the characteristic parameter ,P,. Six structural types with wide transmission ratios were proposed. In combination with the analysis model， the relationship between the transmission ratio and efficiency is discussed， and the transmission ratio range that there must be a cycle power in the condition of characteristic parameter ,P, in [3，8] is obtained. Finally， the efficiency of a scheme is analyzed with this method， and the efficiency is improved by changing the tooth ratio.
