摘要
推导出了角接触球轴承轴向刚度的表达式,建立了以轴承刚度为优化目标的目标函数,对角接触球轴承进行优化设计,并以7010C角接触球轴承为例进行实例分析,得出结论:高速精密角接触球轴承优化设计时应更多地考虑刚度,在满足轴承寿命的前提下,应适当减小球径,增加球数。
The expression is deduced for a ia l stiffness of angular contact ball bearings.The objective function is built,which takes stiffness of the bearings as optimizing objective.The optimal design is carried out for angular contact bearings,and the angular contact ball bearings 7001C are taken as examples to analyze.It is concluded that the more consideration should be given for stiffness during optimal design of high speed precision angular contact ball bearings.The ball diameter is reduced appropriately and the ball number is increased under the precondition life.
