轴承外圈加工工艺的改进方法探索

Bearing outer ring processing technology improvement exploration

该工艺结合了热处理和振动时效的优点,提出用热振动来解决轴承加工中的弹性变形问题。其基本工作过程是将被加工零件置于大强度、高频率的交变磁场作用下的恒温油浴中,利用零件自产生的两种物理变化——磁畴振动和运动来释放工件的内应力来稳定零件尺寸。工艺投入使用后,经现场反馈信息证明,该工艺具有良好的经济技术指标。

This process combines the advantages of heat treatment with vibration by thermal-vibration to solve the problem of elastic deformation bearing processing.Its basic working process is using spontaneously physical changes to release the internal stress of work piece to stable size with work piece into oil bath.Process was put into use,the field feedback information proves that this technology has good economic and technical indexes.
