某热轧厂精轧机组故障分析

Fault analyses ofthe Finishing Mill Group in a Hot Rolling Mill

通过对某热轧厂F1轧机减速箱和F6精轧机组人字齿轮座典型位置振动信号的实测和频谱分析,发现F1减速机本身及人字齿轮座均无明显故障,但钢坯咬入时轧机机组受到巨大冲击;F6轧机在咬钢和抛钢瞬间存在强大冲击振动,F6齿轮座振动过大的原因是由接轴不平衡而并非齿轮出现调节误差所造成的.建议通过调整F1轧机机前辊道输送速度以降低钢坯咬入时对轧机的冲击,并做现场动平衡试验调节节轴平衡,以减小轧机机组在咬钢与抛钢时产生的冲击振动.

Based on the measured vibration data data on the double helical gear housing of a Ho instant powerful impact on the mill units F6 an and the powerful vibration came from imbalance In order to eliminate the additional vibration, t and the balance of the spindle have to be adjust and the results of the frequency spectrum of the measured t Rolling Mill Unit F6, the paper found that there was an d F7 when the strip steel entered and got out of the units, of the spindles but not the circular pitch error of the gears. he paper suggests that the entering speed of the conveyor ed.
