Application of Multilevel Technique to the Elastohydrodynamic Lubrication of Gear

对齿轮的弹流润滑问题应用多重网格技术进行了数值计算与分析,并用于分析齿轮的弹流润滑性能。计算结果表明,多重网格技术应用于齿轮弹流数值计算具有收敛速度快、数值稳定性好等优点。增大齿轮的模数、传动比和压力角等参数,以及提高转速、增大润滑油粘度可以提高齿面间的润滑油膜厚度。

The elastohydrodynamic lubrication (EHL) numerical analysis of an involute spur gear was made by multilevel algorithm. The results show that the algorithm has advantages of high convergent speed and good numerical stability. The calculation and analysis indicate that the oil film thickness become thicker with the increase of gear modulus, reduction ratio, pressure angle, rotating velocity and oil viscosity.
