摘要

为探究内啮合齿轮传动的热弹流润滑特性，考虑多种齿轮传动类型及不同变位系数和的影响，建立了内啮合齿轮传动的热弹流润滑模型，分析了内啮合齿轮系统的热弹流润滑特性。结果表明，与其他齿轮传动类型相比，对于采取变位的内啮合齿轮传动系统，当实现正传动时，其润滑效果最佳，在啮合轮齿间可以形成较厚的润滑油膜，摩擦因数和油膜的最高温升最小，热胶合承载能力最强；当实现正传动时，适当增加内齿轮与行星齿轮的变位系数之和，可以进一步改善内啮合齿轮齿面的润滑特性，但同时降低了油膜刚度。

Abstract

In order to find out the thermo-elastohydrodynamic lubrication characteristic of internal meshing gear transmission，considering the influence of various gear transmission types and different modification coefficients，an elastohydrodynamic lubrication model for the internal meshing gear transmission is established to analyze the thermo-elastohydrodynamic lubricating characteristics of internal meshing gear system. The research shows that compared with other transmission types，for the modified internal meshing gear system，when the positive transmission is realized，the lubrication effect of the gear system is the best，the thick lubricating oil film can be formed between the meshing gear teeth，the friction coefficient between the gear teeth and the highest temperature rise of the oil film are the least，and the thermal adhesive bearing capacity is the strongest. When positive transmission is realized，appropriate increment of the modification coefficient can further improve the lubrication characteristics of the tooth surface，but at the same time reduce the oil film stiffness.
