Abstract
Based on Lagrange equations, the dynamic model of an internal parallel moving gear transmission mechanism with two parallel moving gears distributed symmetrically was established. Through the analysis of relative displacement meshing function and dimensionless disposing, a 6 degrees of freedom dimensionless differential equation of the system was obtained. And through the analysis of the impacts on system's dynamical characters caused by asymmetrical factors, such as asymmetry of axial bearings disposal, asymmetry of meshing clearances or asymmetry of loads on two parallel moving gears, it is indicated that all these three types of asymmetrical factors will result in bifurcation of the system. Besides, different asymmetrical factors will lead to different distribution of the chaos area and different characteristics of periodic solutions.
