摘　　要：针对轴承环在冷碾压过程中产生的残余应力,采用振动时效工艺是较为经济的方法。通过振动时效的方案对比和振动时效前后残余应力的实验分析,发现采取由高到低分段设置振动频率方法实施振动时效处理,有利于降低残余应力。It is a more economical method to use the vibratory stress relief process for the residual stress generat-ed by the bearing ring during cold rolling. Through the comparison of the scheme of vibratory stress relief and theexperimental analysis of the residual stress before and after the vibratory stress relief, the results show that takingfrom high to low setting vibration frequency method of vibration aging, help to reduce the residual stress.
