正交试验法解决轴承锻坯外圈锥度超差

Solving measure for the overproof of bearing outer ring's taper

针对技改目标厂应用原设计工艺生产某型圆锥轴承外圈时 ,在辗压过程中出现的外径锥度超差缺陷 ,从材料力学角度进行了定性分析 ,指出了缺陷产生的原因 。

Aim at the overproof of taper in rolling process for bearing outer ring, an qualitative analysis was made with mechanics of meterial,then the best measure for improving the process is brought forward.
