E68813Q斜盘轴承失效分析

A failure analysis of E68813Q bearing with aligning housing washer

就E68813Q斜盘轴承失效进行实险分析的结果说明，轴承失效原因是钢球的早期疲劳剥落；金相分析说明碳化物在晶界上的大量析出是钢球产生裂纹和早期疲劳剥落的主要因素。附图9幅，表1个。

At the point of the failure cause of E68813Q bearing with aligning housing washer, a testing and an analysis were made, the result sh-ows that the failure cause of bearing is insipient fatigue flaking of balls; Metallographic analysis al-so shows that a lot of carbide separate out of the crystal boundary is the main cause of producing cracks and incipient fatigue flaking on balls.
