摘要

采用赫兹接触理论和有限元接触分析相结合的方法,系统地分析了高分子齿轮齿面接触压力,研究了啮合过程中轮齿的齿面摩擦因数以及摩擦热流密度的计算方法;探讨了聚醚醚酮（PEEK）高分子齿轮啮合传动过程中轮齿瞬时接触温度场和应力的分析模拟方法。采用直接耦合法对齿轮进行热-结构分析,得到齿轮啮合时的瞬态温度场与应力,同时对影响结果的初始环境温度进行讨论。结果表明,初始环境温度的升高对啮合时的温度场、应力都有着很大的影响。

Abstract

The contact pressure of the tooth surface of the polymer gear is analyzed by using the method of Hertz contact theory and finite element contact analysis. The calculation method of the tooth surface friction coefficient and the friction heat flux density of the gear tooth during the meshing process is studied. The simulation method of temperature field and stress in the instantaneous contact temperature of the gear teeth during the meshing transmission of PEEK polymer gear is discussed. The direct coupling method is used to analyze the heat-structure of the gears,and the transient temperature field and stress are obtained. The results of the initial ambient temperature are discussed. The results show that the increase of the initial ambient temperature has a great influence on the temperature field and the stress at the time of meshing.
