Design Of Process Technology Of 4D Series Diesel Engine Crankshaft

With the quick forward development of society, the living standard of people is constantly raised, and the requirement to the various capabilities of automobile of people is also more and more higher. Among them motive force and safe nature of automobile and emission capability have become the major content that people are concerned about. Except possesses the design structure of first-in, the process quality of each parts of automobile is also giving play to the most importance effect. As the main parts of automobile, the process quality of the parts of engine is the foundation of whole automobile process. Crankshaft is one of the main parts of internal combustion engine,which is in charge of converting position back and forth movement into rotating movment ,undergoing complicated interaction stress,affecting the life of internal combustion engine drictly,the advanced design and the resonable manufacturing process technology are most important surport to improvethe life of crankshaft and keep the engine in normal position. This dissertation takes the design of manufacturing process of 4D series crankshaft for example,doing some reserch on key point,for example,drilling central hole,balance, maching of neck of crankshaft. And Utilizing it in practice,improving the quality of old production,finishing the 4D series crankshaft on time.
