Non-linear dynamic analysis of an internal parallel moving gear system driven by single parallel moving gear

YANG Jian-xin1,ZHOU Song-hua2,CHENG Ai-ming1,ZHANG Chun-lin1(1.School of Mechanical and Vehicular Engineering,Beijing Institute of Technology,Beijing 100081,China;2.Jinggangshan University College of Electronics and Information Engineering Jiangxi,343009 China)  
Here,a gear model contained two gears.The inner gear was drived by a single parallel moving gear.Non-linear factors including gear backlash clearances,bearing clearances and gear meshing stiffness fluctuations were considered.Among them,the meshing stiffness fluctuations was resulted from multi-tooth contacting.Based on these factors,the differential equations of the motion of the system were established.At different rotation speeds the bifurcation characteristics of the system were investigated.The analysis results showed that not only the collision vibration characteristics of each motion pair change with the rotation speed,but also the collision vibration of each motion pair are different from each other.
