Influence of undissolved gas on the characteristics of high-speed water-lubricated bearings

  • 摘要: 水润滑轴承相比传统油润滑轴承,凭借其独特的优势,在各类高速精密旋转机械中均有重要应用.在实际工况中,润滑水中不可避免的混入一定量的难溶气体,参与整个润滑过程.运用计算流体力学CFD软件Fluent,基于气液两相流理论,对考虑湍流及气穴效应的高速水润滑轴承特性进行求解分析,研究难溶气体的含量对轴承间隙气相分布、压力峰值、轴承性能等特性的影响.结果表明:在高速水润滑轴承间隙中,气相基本分布于发散楔中,且最大气体体积分数存在于轴表面;在较小偏心情况下,一定量的难溶气体使轴承间隙内气相分布发生偏移,轴承承载力有所降低,但是对压力峰值和摩擦功耗并无明显影响;随着轴承偏心的增加,影响逐渐消失.
