柴油机工作时,曲轴摩擦表面运动速度高,散热条件差,不仅容易造成轴颈磨损,还会出现整体弯曲、扭曲变形,甚至产生裂纹或折断。所以在柴油机解体清洗后,应对曲轴进行仔细检查,并根据损伤部位和损伤程度,采取相应的修理方法。现以康明斯B系列柴油机为例,说明曲轴损伤的检修要点。 Diesel engine work, the crankshaft friction surface moving speed, poor cooling conditions, not only easily lead to journal wear, but also appear overall bending, distortion, and even crack or break. Therefore, after the disassembly and disassembly of the diesel engine, the crankshaft should be carefully inspected, and the corresponding repair methods should be taken according to the damaged parts and the degree of damage. Now Cummins B series diesel engine, for example, explain the crankshaft damage repair points.
