我厂合成车间2AL15—l型氨压机曲轴由于某种原因导致皮带震动,轮健功率过大超过了轴键槽的负载能力,而引起从轴键槽起沿整个轴的纵向裂纹,长达120毫米,深达7～9毫米。在本厂无备件的情况下,为了不影响生产,我们组成了以工人为主体的三结合小组,对曲轴裂纹的产生做了认真的分析,并提出了采用镶钢套和电弧冷焊的方法,对曲轴进行修复。实践证明,修复后的曲轴运行很好,尚未发现异常现象2AL15—1型氨压机的曲轴材料为QT60 I plant synthesis workshop 2AL15-l-type ammonia compressor crankshaft for some reason leading to belt vibration, wheel health power exceeds the shaft keyway load capacity, causing the shaft along the shaft from the longitudinal crack along the entire axis, up to 120 mm , Deep as 7 ~ 9 mm. In the absence of spare parts in the factory, in order not to affect the production, we formed a combination of workers as the main body of the three, a careful analysis of the crankshaft crack produced and put forward the use of steel bushings and arc welding method , The crankshaft repair. Practice has proved that the repaired crankshaft is running well, no abnormalities have been found 2AL15-1 ammonia press crankshaft material for the QT60
