Study Of Phase Difference And Eccentric Mechanism For Adjusting The Center Distance

For lately year,with the fast development of automotive industry especially the heavy truck,the demanded quantities of shaft parts with larger diameter are more and more imperative.As a perfect techniques to form shaft parts,cross wedge rolling(CWR)has been widely applied because of its lots of merits,such as remarkable saving material and higher produced efficiency,etc.The size of the equipment of CWR is increasingly bigger.But up to now,it is nearly not found in the world that research of mechanism for adjusting the center distance of two rolls and correlative with it.So the thorough research of them has important meaning to the CWR further development.By using kinematics?dynamics principle and ADAMS,This text carried on a great deal of calculation and computer simulation.It studied the affect to the phase change by different center distance,and get variety rule,by using eccentric mechanism for adjusting the center distance of two rolls.The simulation value are consistent with the value tested on the real CWR machine.By using method of optimal design,This text optimized eccentric mechanism for adjusting the center distance.This text analyzed the affect to the extreme phase difference change by different design parameter(the position parameter of eccentricity and the value of eccentricity),and get variety rule,by analyzing all data that came from optimal design process.And it get variety rule about extreme phase difference and minimum contact ratio of interim gear and gear of roller,by analyzing all data that came from optimal design process.All of this got data reference and design basis for eccentric mechanism for adjusting the center distance and others.
