船用柴油机的大型曲轴机械加工工艺浅析

Analysis of machining techniques of large crankshaft used by ship's diesel engine

曲轴是活塞式发动机的主要零部件之一,加工工艺复杂、要求高。船用柴油机的大型曲轴在尺寸和重量上都比普通曲轴大上很多,结合其它曲轴的加工工艺,深入分析船用柴油机的大型曲轴机械加工工艺,并对曲轴机加工发展方向进行了初步探讨。

Crankshaft is one of main parts for piston-type engine.It needs difficult machining tech-niques.The large crankshaft used by ship＇s diesel engine is very bigger and heavier than ordinaire crankshaft.It analyzes deeply machining techniques of large crankshaft used by ship＇s diesel engine.A preliminary discussion on development direction for crankshaft is made.
