【摘要】 对挠性表面径向气体轴承进行了理论分析。提出一种同时考虑轴承孔圆度误差及柱度误差和弹性变形的气膜厚度分布表达式，分析了加工误差对轴承静特性（承载能力、摩擦力矩、姿态角）的影响，并与刚性表面轴承作了对比分析。结果表明，挠性表面轴承对加工误差的敏感程度较刚性表面轴承低，故在不使轴承性能下降过多的情况下，可以设置较大的加工允许误差，从而达到降低加工成本的目的。更多还原

【Abstract】 A theoretical study has been performed to investigate the influence of manufacturing errors on the bearing housing of a gas lubricated journal bearing with compliant surface I in particular on the bearing load capacity. A gas film thickness distribution is presented, in which errors o f both circumferential and axial bearing housing are considered. The influence of the errors on bearing performance is compared between rigid and compliant surface bearings. It was shown that the compliant surface bearings are less sensitive to the manufacturing errors than the rigid surface bearings. Thelefore, the cost of compliant surface bearing could be reduced by setting a larger manufacturing error tolerance.更多还原
