摘要

为研究双渐开线齿轮传动摩擦学与动力学之间的耦合作用，根据齿轮动力学、载荷分担及弹流润滑理论，建立双渐开线齿轮传动摩擦动力学模型，研究混合弹流润滑特性与动力学之间的耦合作用。将动力学模型求解的动载荷应用于混合弹流润滑模型，求解摩擦因数等参数；将摩擦因数重新代入动力学模型，研究双渐开线齿轮动力学行为。结果表明，考虑摩擦学与动力学耦合作用对齿轮动力学行为影响较显著；低转速时，动载荷作用下摩擦因数及油膜厚度分布与稳态载荷作用时近似，转速增大时，摩擦因数及油膜厚度分布波动明显。

Abstract

In order to study the coupling effect between tribology and dynamics of double involute gear transmission， according to the gear dynamics， load-sharing， and elastohydrodynamic lubrication theory， the friction dynamics model of double involute gears is established， the coupling effect between elastohydrodynamic characteristics and dynamics is studied. The dynamic load solved by the dynamics model is applied to the mixed elastohydrodynamic lubrication model to solve the friction coefficient and other parameters. The friction coefficient is put back into the dynamics model to study the dynamics behavior of double involute gear. The results show that the coupling effect of dynamics and elastohydrodynamic lubrication has a significant effect on the gear dynamics behavior. At low rotating speed， the distribution of friction coefficient and oil film thickness under dynamic load is similar with that under steady load， whereas those distribution changing obviously when the rotational speed increases.
