Main causes of crankshaft fracture

Author：

(1) The engine oil deteriorates after long-term use; Serious overload and over coupling cause long-term overload operation of the engine and Bush burning accident. The crankshaft was severely worn due to the burning of the engine pad.

(2) After the engine is repaired, the loading has not passed the running in period, i.e. overload and overload, and the engine has been overloaded for a long time, so that the crankshaft load exceeds the allowable limit.

(3) In the repair of the crankshaft, surfacing welding was used, which damaged the dynamic balance of the crankshaft, and no balance verification was carried out. The imbalance exceeded the standard, causing the engine to vibrate greatly, resulting in the fracture of the crankshaft.

(4) Due to poor road conditions and serious overload and over coupling of vehicles, the engine often runs within the critical speed of torsional vibration, and the failure of the shock absorber will also cause the fatigue damage of crankshaft torsional vibration and fracture.
