讨论了角接触球轴承轴向刚度的计算问题。在获得单列轴承预载荷与刚度基础上,利用轴承载荷、位移和刚度的相互关系确定了多联组配轴承的预载荷与刚度。分析了双联和多联组配轴承预载荷与刚度的相对值,并与SKF和NSK公司进行了对比,结果表明,误差均在3%之内。

The axial rigidity calculation of angular contact ball bearings is discussed.Based on preload and rigidity of single row bearings,the preload and rigidity of multiplex matched bearings are determined by using relationship among load,displacement and rigidity.The relative value of preload and rigidity of coupled and multiplex matched bearings is analyzed and compared with SKF and NSK.The results show that the errors are below 3%.
