摘　　要：在轧机装备的设计过程中,对角接触球轴承的静特性分析是进行轴承动特性计算,确定轧辊轴承选型的首要工作。本文基于Hertz点接触理论建立了球轴承的静力学平衡方程,并对角接触球轴承的接触角分布、接触载荷分布、接触变形、轴承内外圈位移及刚度进行了计算。以轧辊轴承FAG-7206B-TVB为研究对象,对其进行静态特性数值分析,并将计算结果与传统简化算法进行了比较,验证了本方法在进行角接触球轴承静特性分析的有效性和精确性。In the design process of rolling mill equipment,the static characteristic analysis of the angular contact ball bearing is the first work to calculate the dynamic characteristic of the bearing and determine the type selection of the roll bearing.Based on Hertz point contact theory,the static balance equation of ball bearing is established in this paper,and then the contact angle distribution,contact load distribution,contact deformation,bearing inner and outer ring displacement and stiffness of the angular contact ball bearing are calculated.Taking roll bearing FAG-7206 B-TVB for example,after the numerical analysis of its static characteristics,the results are compared with the traditional simplified algorithm,this method is proved to be effective and accuratein the static characteristics analysis of angular contact ball bearing.
