In full consideration of time-varying meshing performance and oil film characteristics, entrainment effect on elastohydrodynamic lubrication (EHL) is developed for establishing accurate forecasting model of the complex hypoid gears. Firstly, dynamic loaded tooth contact analysis (DLTCA) is employed to determine the meshing interface kinematics, load distribution and entrainment speed under dynamic load condition. Then, entrainment speed is introduced into the EHL governing equation and accurate forecasting model is established. With accurate discretization of EHL governing equation, discrete convolution and fast Fourier transformation (DC-FFT) method is employed to compute the flank elastic deformation. Finally, a hypoid gear set in automotive industrial application is exercised to verify entrainment effect on EHL assessment in the proposed model.

考虑夹带效应的准双曲面齿轮弹流润滑预测模型

充分考虑时变啮合性能和油膜特性，提出了弹流润滑（EHL）的夹带效应，以建立复杂准双曲面齿轮的准确预测模型。首先，采用动态加载齿接触分析（DLTCA）来确定动态负载条件下的啮合界面运动学、负载分布和夹带速度。然后将夹带速度引入EHL控制方程并建立准确的预测模型。通过对EHL控制方程进行精确离散，采用离散卷积和快速傅里叶变换（DC-FFT）方法计算齿面弹性变形。最后，通过汽车工业应用中的准双曲面齿轮组来验证所提出模型中 EHL 评估的夹带效果。
