摘要
点接触弹流润滑的实际计算较为复杂,对点接触弹流油膜厚度及摩擦力矩的计算进行了详细分析并给出了计算实例。同时对弹流油膜厚度与轴承摩擦力矩的关系进行了探讨,提出了新的摩擦力矩经验计算公式。
The practical calculation of EHL in elliptical contact zone is relatively complex.The detailed calculation of oil film thickness in EHL elliptical contact zone and an example are given.At the same time,relations between oil film thickness in EHL elliptical contact zone and bearing friction torque are discussed.A new bearing empirical friction torque expression is built.
