然后检查两个半联轴节的内孔直径和长度是否同原动机、工作机的直径和轴伸长度尺寸相符。

Then check the hole two and a half coupling is the same diameter and length of the original motivation, job machine diameter and shaft length of the size of match.

利用化学分析、力学性能分析及金相分析等手段，对初轧机接轴半联轴节失效原因进行了分析。

The failure of the spindle half-coupling on the bloomer has been analysed by many methods, such as chemical analysis, mechanical property analysis and metallographic analysis.
