运用有限差分法,对螺旋油楔动静压轴承进行了数值计算,分析了油膜破裂规律和影响油膜破裂的因素。结果表明:螺旋角是影响油膜破裂位置的主要因素。当螺旋角变化时,油膜破裂位置沿周向的偏移角度与螺旋角变化值基本相等;供油压力和转速对油膜破裂面积影响较大。
According to the finite differential method,the spiral oil wedge hybrid journal bearing was investigated,and the rupture regular and effect factors of oil film were analyzed. The results show that the spiral angle is an important factor to the rupture location. When the spiral angle changes,the deviation angle of the rupture location is equal to the change of the spiral angle,and the offering pressure and the rotate speed have great effect on the rupture areas.
