摘　　要：在航空发动机高速圆柱滚子轴承拟静力学分析基础上,建立基于轴承径向游隙的高速圆柱滚子轴承非线性刚度计算模型,分析了轴承内、外圈转速对高速圆柱滚子轴承工作径向游隙影响的关系,并对高速圆柱滚子轴承非线性刚度特性进行了研究,最后就某型号航空发动机主轴高速圆柱滚子轴承进行了实例计算与分析,得出在满足主机支承刚度条件下的合理高速圆柱滚子轴承工作径向游隙使用范围。On the base of high- speed cyclinderical roller bearing pseud os tatic analysis of aircraft engine,this paper established nonlinerity rigidity co mputation model based on bearing radial play of high- speed cyclinderical rolle r bearing,analyzed relationship that inner、 outer ring of bearing effect workin g radial play of high- speed cyclinderical roller bearing,and studied on nonlin erity rigidity property of high- speed cyclinderical roller bearing,in the end, we performed example calculation and ananysis in light of some model main- shaf t high- speed cyclinderical roller bearing of aircraft engine,drawed using rang e of working radial play of fair high- speed cyclinderical roller bearing on th e condition of meeting main frame supporting rigidity.
