摘要

针对NGWN（Ⅱ）行星传动效率低、承载能力较差的问题,提出采用低耗非对称齿轮提升NGWN（Ⅱ）行星齿轮传动效率与承载能力的设计方法。研究重合度对系统传动效率、以及压力角、变位系数对系统强度的影响规律;在此基础上,构造出以配齿、干涉、强度等为约束条件,以系统传动效率和功率密度为目标的优化设计数学模型,采用遗传算法对实例进行优化计算;分析结果表明,提出的设计方法和优化得到的设计参数,能有效地提高系统的传动效率和承载能力。

Abstract

Aiming at the low efficiency and low carrying capacity of NGWN（Ⅱ） planetary transmission,a design method which improve the efficiency and carrying capacity of the system by using low-loss and asymmetric gears is given. The efficiency influenced by contact ratios and the strength influenced by pressure angles and profile-shift coefficient are studied. On this basis,an optimization model aimed at highest efficiency and power density is described,which is subject to the conditions such as teeth,interference and strength. The research results show that the design method and the optimized design parameters can improve the transmission efficiency and carrying capacity of the system effectively.
