摘要： 高速重载齿轮常常工作在混合润滑状态，为了准确预测齿面的磨损程度，提出一种油润滑齿轮的磨损分析模型，使其能够在微观尺寸上对混合润滑齿面的磨损过程进行准确地描述.依据实测的齿面形貌特征生成非高斯粗糙面，将热-应力耦合分析结果作为混合润滑分析的工况条件和初始条件，研究一定工况下齿面的应力分布、润滑状态及磨损趋势，进而揭示了齿面磨损机理.结果表明:油润滑齿面磨损率受多重因素综合影响;粗糙峰的形状及分布方向会显著影响齿面的磨损程度;磨损率的预测结果与试验数据较为一致，表明混合润滑齿面的磨损预测方法具有实际工程意义.

Abstract: High-speed heavy-duty gears often work in a mixed lubrication state. In order to accurately predict the wear level of tooth surfaces， a wear analysis model of oil-lubricated gears was proposed to enable accurate description of the wear process of mixed lubrication tooth surfaces at the microscopic dimensions. The non-Gauss rough surface was generated according to the as-measured tooth profile characteristics， and the coupling results of thermal-stress were used as the working conditions and initial conditions of mixed lubrication analysis. Then pressure distribution， lubrication state and wear trend of the tooth surface were studied to reveal the wear mechanism. The results showed that surface wear of oil lubricated gears is affected by miscellaneous factors. In particular， the shape and distribution direction of asperity have a significant effect on wear degree. The prediction results show good agreement with the experimental measurements. It indicates that the wear prediction method of mixed lubrication tooth surface has practical engineering significance.

Key words: spur gears, tooth surface wear, mixed lubrication, asperity contact, wear experiments
