我厂从一九七○年开始焊接修复折断曲轴,主要是修复各种机型的多缸曲轴,马力最大的为300匹,经生产使用,效果良好。曲轴的断裂一般发生在连杆轴颈(连杆轴颈根部折断或通过连杆轴颈的油孔沿45°角折断)或曲柄处。修复工艺如下:1、清洗检查焊前,用汽油把曲轴的断面清洗干净,对喷镀的曲轴应把喷镀层清除掉,并进行认真的检查。2、焊前定位夹固把曲轴置于专用夹具上,利用主轴颈进
Since 1970, our factory has been repairing the broken crankshaft by welding. The main purpose is to repair the multi-cylinder crankshafts of various models. The maximum horsepower is 300 horsepower, which is produced and used well. Crankshaft rupture typically occurs at the connecting rod journal (the root of the connecting rod breaks or breaks through the oil hole in the connecting rod journal at a 45 ° angle) or at the crank. Repair process is as follows: 1, cleaning inspection Before welding, the section of the crankshaft with gasoline to clean, the spraying of the crankshaft should be sprayed layer removed, and careful examination. 2, the positioning fixture before welding the crankshaft placed in a dedicated fixture, the use of spindle neck into
