摘要

摘要: 陶瓷球轴承作为电主轴的核心部件,其结构参数对电主轴的静刚度有着重要的影响。基于角接触球轴承径向刚度计算公式,通过仿真分析研究了接触角和预紧力对电主轴静刚度的影响。通过建立的主轴-轴承系统三维有限元模型,仿真获得了不同接触角和预紧力下主轴前端径向变形及主轴静刚度,进而根据有限元仿真结果拟合得到了主轴静刚度关于接触角和预紧力的拟合方程及拟合曲线。

Abstract: As a core component of electric spindle, ceramic ball bearings as well as its structure parameters play acritical role to the static stiffness of spindle. The impacts of contact angle and preload of ceramic ball bearing on thestatic stiffness of high-speed grinding motorized spindle are studied in this article using finite element method andsimulation skills based on angular contact ball bearing stiffness computational formula. The three-dimensional finiteelement model of the spindle-bearing system is built. radial deformations of spindle front-end and the spindle staticstiffness with various contact angles and bearing preloads are obtained. The fitting curves and formulas, whichcould be benefit to electronic spindle bear selection and structure parameters design, are figured out according tothe simulated results.
