含沟槽结构的水润滑橡胶轴承三维弹流润滑分析

摘要

In full view of the elastic deformation of rubber of water-lubricated rubber bearings and the geometric construction with multi-curve and multi-vertical grooves, the author employs finite element analysis software " ANSYS CFX" to do numerical simulation of three dimensional EHL for water-lubricated rubber bearings with grooves, researching the variation of water film pressure distribution, waterfilm thickness distribution, carrying capacity and frictional factor under different eccentricity and totate speeds. The results show that the elastic deformation of rubber and the geometric construction with multi-curve and multi-vertical grooves can have significant influence on the lubricating property of the bearing.%综合考虑水润滑橡胶合金轴承橡胶弹性变形以及其多曲面、多纵向凹槽的几何结构,利用有限元ANSYS CFX软件进行含沟槽结构的水润滑橡胶合金轴承三维弹流润滑数值仿真,研究不同偏心率、转速对水润滑橡胶合金轴承的水膜压力分布、水膜厚度分布、承载能力以及摩擦系数的影响,研究结果表明橡胶弹性变形及多曲面、多纵向凹槽的几何结构对轴承润滑特性影响显著.
