摘　　要：采用有限元方法研究了制造误差对狭缝节流气体静压轴颈止推串接型轴承的涡流力矩的影响,主要分析了狭缝宽度误差和轴颈圆度误差对涡流力矩的影响,以及轴颈的不同安装角度、偏心等因素对涡流力矩的影响。经对比验证表明,有限元计算结果与实测结果基本一致,研究结果对于气体静压轴颈止推轴承的设计、装配优化和性能预测具有重要的指导意义。The effects of part’s manufacturing errors on the vortex torque of the externally pressurized gas journal-thrust bearings with slot restrictors were studied by finite element method,including the influence of slot width error and shaft surface roundness error,as well as the effects of installation angle and eccentricity of journal.Predicted characteristics are in good agreement with experimental results. Research results have great significance for the design, assembly optimization and performance prediction of gas bearings.
