摘　　要：为了研究轴瓦支点摩擦力对其润滑性能影响,建立可倾瓦径向滑动轴承的支点摩擦力的数学模型,分析其对轴承的润滑特性,如油膜压力、厚度、摩擦阻力、功耗及轴承承载力和流量的影响,得出支点摩擦力的影响作用较大的结论,因此在设计可倾瓦径向滑动轴承的过程中,考虑支点摩擦力的影响很有必要。A mathematical model of pad-pivot friction of tilting pad journal bearing was established in order to study and analyze its influence on lubrication characteristics of the bearing,such as fluid film pressure,thickness,frictional resistance,power consumption,bearing load and rate of flow.The result shows that pad-pivot friction affects the lubrication characteristics of tilting pad journal bearing and there is necessity of taking into account of its influence in the process of designing tilting pad journal bearing.
