During calculation, the concepts of a new upper boundary condition (UBC) of oil flow and the average viscosity across the oil film thickness were used.
在计算过程中,采用了不完整的上游边界及沿膜厚方向的平均粘度概念。
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.
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。
Calculation of the oil film thickness of the crack shaft has been carried out according to elastohydrodynamic lubrication theory, which confirms the outcome.
并运用弹性流体动力润滑理论对曲轴轴颈油膜厚度进行了计算,验证了实际使用时出现的结果。
