摘要

为探究非对称齿廓的内啮合齿轮在变位情况下的热弹流润滑特性，用多重网格法对采用变位设计的非对称聚合物齿轮进行了瞬态热弹流润滑分析，比较了不同传动类型的变位齿轮的弹流润滑特性，分析了不同变位系数分配形式以及齿廓修形对非对称聚合物齿轮在内啮合情况下的瞬态弹流润滑的影响。结果表明，非对称齿轮能改善变位齿轮的润滑性能，正传动的变位类型的齿轮润滑性能最优，内齿轮采用较大的变位系数对热弹流润滑更为有利，合理的修形能够改善非对称变位齿轮的润滑性能。

Abstract

In order to investigate the thermo elastohydrodynamic lubrication characteristics of internal meshing asymmetrical gears with addendum modification， the transient thermo elastohydrodynamic lubrication of asymmetrical polymer gears with addendum modification is analyzed by the multi-grid method. The elastohydrodynamic lubrication characteristics of modified gears with different transmission types are compared. The effects of different distribution forms of modification coefficients and tooth profile modification on the transient elastohydrodynamic lubrication of asymmetrical polymer gears under internal meshing are analyzed. The results show that asymmetrical tooth profile can improve the lubrication performance of the gears with addendum modification， and the positive transmission gear has the best lubrication performance. The larger modification coefficient of the inner gear is conducive to the thermo elastohydrodynamic lubrication performance. The moderate tooth profile modification can improve the lubrication performance of the asymmetric gears with addendum modification.
