As to the high speed of electric spindle system , the angle - contact bearings are usually applied to supporting the shafts . because the supporting stiffness of rolling bearing is non - linear , especially under the circumstances of high speed and ultrahigh speed , the internal working status is so complicated that it is not regarded as routine linear support and ordinary non - linear support . centrifugal effect of the rolling bearing increase the factors of influencing the supporting stiffness 高速电主轴系统的转速很高，通常都采用角接触球轴承作为支承，由于滚动轴承的支承刚度呈非线性形式，特别在高速和超高速情况下，滚动轴承内部的动力学状态十分复杂，由于滚动体运动所产生的离心力作用，使得影响其支承刚度的因素增多，不能作为常规的线性支承和普通的非线性支承处理。
