在考虑橡胶轴瓦弹性变形基础上，建立水润滑轴承的弹流润滑模型并进行数值计算，从理论上分析水润滑橡胶层厚度对轴承弹流润滑性能的影响。结果表明：一定范围内，相同材料不同厚度的橡胶轴瓦对水润滑轴承水膜压力和厚度有着较大影响。随着橡胶层厚度的增加，水膜压力减小，水膜厚度增加，弹流润滑效果越好；相应地，水润滑轴承所承受的摩擦力会减少，摩擦因数会出现降低的趋势。

Considering the elastic deformation of the rubber bush,the water-lubricated bearings elastohydrodynamic lu-brication(EHL)model was set up and calculated with numerical method,the effects of the thickness of water-lubricated rubber material on the EHL performance of bearings were analyzed in theory.The results show that same rubber materials with different thickness within a certain range have a great impact on the water film pressure and thickness of water-lubri-cated bearings.Along with the rubber layer thickness increasing,the water film pressure is decreased,the water film thick-ness is increased and a better EHL performance is obtained.Accordingly,the friction on the water-lubricated bearings is re-duced and the friction coefficient is decreased.
