Research on Optimisation of Crankshaft Machining Process for a Certain Model of High-Power Diesel Engine
The crankshaft is the core component of diesel engine,with a complex structure,whose deformation and fatigue resistance directly affect the reliability of diesel engine.Aiming at the crankshaft in the process of processing process on the crankshaft deformation law influence is unclear,the role of the mechanism is unknown and other issues,to carry out the optimisation of the crankshaft machining process research.Through experimental verification,the results show that adjusting the number of high-temperature aging can effectively eliminate the residual stress inside the crankshaft;two times of fine grinding of the main journal and connecting rod journal,the crankshaft coaxiality can be controlled within φ0.05 mm;optimisation of the crankshaft machining process can effectively reduce the deformation of the finished crankshaft.
