Abstract

A methodology is proposed to study the interplay between tooth wear and contact fatigue under elastohydrodynamic lubrication condition. The modeling methodology includes the influence of contact fatigue on wear and the influence of wear on contact fatigue. Firstly, the changes of film pressure and shear force of oil at each meshing point caused by contact fatigue are introduced according to the surface wear model, and the change of wear model is analyzed to study the effect of contact fatigue on wear. Then, according to the elastohydrodynamic lubrication theory, the change in film pressure affected by tooth surface wear is analyzed to study the effect of wear on contact fatigue. Finally, the influence of lubrication conditions on the interplay between tooth surface wear and contact fatigue are analyzed. In addition, an experimental fatigue study is performed and introduced into the model predictions to improve the accuracy of the proposed methodology.
齿轮表面磨损与接触疲劳的相互作用
提出了一种研究弹流润滑条件下齿面磨损与接触疲劳相互作用的方法。建模方法包括接触疲劳对磨损的影响和磨损对接触疲劳的影响。首先,根据表面磨损模型,引入接触疲劳引起的各啮合点油膜压力和油剪切力的变化,分析磨损模型的变化,研究接触疲劳对磨损的影响;然后,根据弹流动力润滑理论,分析齿面磨损对膜压力变化的影响,研究磨损对接触疲劳的影响。最后,分析了润滑条件对齿面磨损与接触疲劳相互作用的影响。此外,还进行了疲劳试验研究,并将其引入模型预测中,以提高所提出方法的准确性。
