State-of-the-Art of Joining Technologies for Assembled Camshaft

Abstract:

Assembled camshaft has used gradually in engines for automotive, ship etc. The camshaft bearing a great deal of impact loads and dynamic torque when the engine is high-speed rotation.Its quality directly determines engine combustion and dynamic characteristics. Hence, how to improve the joint strength economically between the shaft and the cam lobes is one of the key technologies needed to be solved. Main methods offered to the designers which can be used for assembled camshaft are: expanding technologies, interference-fits technologies and bonding technologies. It can be divided into joining by mechanical expanding, hydroforming, electromagnetic forming, knurling, welding sintering, injection molding. The advantage and disadvantage of joint techniques are analyzed, the current state of researches are summarized at home and abroad. Then followed are its new approaches in the future development.
