Influence of radial clearance and processing technology on structural properties of gas foil bearing

  • 摘要: 为了分析轴承的加工工艺和径向间隙对轴承静态、动态性能的影响,设计搭建了静态、动态实验台,利用改变轴颈尺寸的方法研究不同径向间隙对气体箔片轴承(GFB)静态性能和动态性能的影响,还分别研究了不同波箔弹性结构、不同箔片材料和不同波箔热处理方式等因素对轴承性能的影响.结果表明:随着径向间隙减小,气体箔片轴承静刚度及其动态结构刚度增大,其等效黏性阻尼随着径向间隙的减小,出现先增大后减小的趋势.在工艺上箔片材料及波箔弹性结构对轴承性能的影响起重要作用.
