高速角接触球轴承静态刚度的分析与计算

Analysis and Calculation on Static Stiffness of High Speed Angular Contact Ball Bearings

在Hertz接触理论的基础上,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静态刚度。计算数据表明,轴向刚度的精确计算与简化计算结果相差较大,而径向刚度的精确计算与简化计算值相差不大。

Based on the Hertz＇s contact theory and Newton- Raphone method,the static stiffness is analyzed and calculated for the high speed angular contact ball bearings with radial load and axial loading in the condition of fixed position preload and fixed pressure preload. The results show that the axial rigidity is much difference and the radial rigidity similar between the accurate calculation and the brief calculation。
