Production Process and Application of Packaged Type Camshaft

The packaged type camshaft is a new technology in engine camshaft production.Compared with tradition-al forged or casting camshafts,packaged type shafts have advantages of lighter mass,lower machining cost and better uti-lization of materials,etc.The production process and application are introduced,specially for their connecting methods and comparisons.There are three main connecting methods,including welding,sintering and mechanical connecting.The three connecting methods have their advantages and disadvantages respectively,and should be used in terms of actual produc-tion.Furthermore,the manufacturing technology,application range and development trends in and out of the country.
