【摘要】 在假定油流为不可压缩、定常、层流的情况下 ,利用计入惯性项的N -S方程组 ,得出了计入惯性项的径向 -推力联合浮环动静压轴承雷诺方程 ,计算了其推力部分的静特性 ,并分析了惯性项对各静特性的影响 .数值解表明 ,在雷诺数不大的情况下 ,惯性项对承力的影响不大 ,而泄流量会随简化雷诺数的增加而增加 .更多还原

【Abstract】 In this paper,the Reynolds equation is extended to include the inertia effect inhydrodynamic and hydrostatic lubrication.Then the influence of inertia term on the static characteristics of the thrust sector in the radial-thrust combined float-ring hybrid bearing is explicitly obtained.Numberical results reveal that the influence of inertia on load-carring capacity is small at moderate value of the reduced Reynolds number and the principal effect of inertia force is a significant increase in the side flow rate.更多还原
