| 摘 要： | 在Hertz接触理论的基本上，结合Newton-Raphone法，针对定位、定压两种不同的预紧方式，分析计算了轴向力和径向力联合载荷作用下高速角接触球轴承的动态刚度，结果表明：定位预紧下轴向刚度和径向刚度随转速增加而增大；定压预紧下轴向刚度随转速增加而减小，径向刚度随转速增加而增大。

| Abstract: | On file base of Hertz theory, pointing to fixed - position preload and fixed - pressure preload, the dynamic rigidities of file high speed angtular contact ball bearing under axial and radial loads are analyzed and calculated by means of Newton - Raphone. The results show that the axial rigidity and radial rigidity are increased with speed increment for file fixed - posi- tion preload and file axial rigidity is decreased with speed increment, radial rigidity is increased with speed increment for file fixed- pressure preload. |
