轴承外圈外径尺寸磨小后的返修

Repair of bearing outer ring with overgrinded OD

根据GCr15轴承钢在回火过程中残留奥氏体和尺寸变化的基本规律,探讨轴承套圈外径过磨废品回火胀形的挽救办法,从而在生产中得到较好的应用。

According to the basic change law of residual auring tempering process, the GCr 15 bearing steel during tempering process, the salvage method to temper and bulge bearing ring rejects with overgringed OD was discussed, so that good application in production was achieved.
