In this study, an interfacial slip model including the limiting shear stress is proposed and applied to the thermal elastohydrodynamic lubrication (EHL) analysis of a helical gear pair. The main difference between the proposed model and the classical EHL model is that, the term of entrainment velocity in Reynolds equation is modified. The influences of interfacial slip, thermal effect, initial limiting shear stress and operating conditions on the tribological properties are evaluated. Due to the interfacial slip, the pressure distribution moves towards the inlet region, and the fluctuation distributions of entrainment velocity and film thickness are similar to the trigonometric function. The influence of thermal effect on interfacial slip cannot be ignored, especially in the case of high speed and heavy load. As the input torque and input rotational speed increase, the interfacial slip gradually extends to the whole meshing process.

考虑润滑剂与齿面界面滑移的斜齿轮副的摩擦学特性

在这项研究中，提出了一种包含极限剪切应力的界面滑移模型，并将其应用于斜齿轮副的热弹流润滑 (EHL) 分析。该模型与经典 EHL 模型的主要区别在于，雷诺方程中的夹带速度项被修改。评估了界面滑移、热效应、初始极限剪切应力和操作条件对摩擦学性能的影响。由于界面滑移，压力分布向入口区域移动，夹带速度和膜厚的波动分布类似于三角函数。热效应对界面滑移的影响不容忽视，尤其是在高速重载的情况下。
