摘要

针对NGWN型大速比行星传动效率低的问题,可采用低耗齿轮设计,即通过同时优化变位系数和齿顶高系数,降低端面重合度以减小啮合功率损失,从而显著提高齿轮传动效率。但重合度改变会对传动系统的动力学性能产生影响。以NGWN（Ⅱ）型行星传动为研究对象,获得了采用低耗齿轮设计的重合度与系统效率的关系;建立动力学模型得到了低耗齿轮设计的重合度与动力学性能的关系,最后给出了采用低耗齿轮设计的重合度选择范围,为高效率、较优动力学性能的大速比行星传动设计提供理论指导。

Abstract

Aiming at the problem of the low efficiency of NGWN-type planetary gear transmission with high speed ratio,the low-loss gear design that is optimizing modification coefficients and addendum coefficients simultaneously,reducing the contact ratio to reduce the mesh power loss can be applied to improve the gear transmission efficiency obviously. However,the change of contact ratio has an effect on dynamics of gear transmission. The NGWN（Ⅱ） type planetary gear transmission is taken as the research object,firstly,the relation between the contact ratio and system efficiency is obtained. Then,the dynamics model of NGWN（Ⅱ） type planetary gear transmission is built,the relation between contact ratio and dynamics performance of low-loss gear design is obtained. In the end,the select range of the contact ratio by using low-loss gear design is given,a theoretical guidance for the design of high-ratio planetary gear transmission with high efficiency and good dynamics performance is provided.
