In order to improve the working efficiency and stationarity

the kinematics analysis of transplanting mechanism with eccentric gear is studied.By using Pro/ E

each component’s 3D model of transplant ing mechanism is built and the whole assembly is completed

then through Mech/ Pro import the model into ADAMS

the kinematics simulation is carried out.On the problem that backlash will cause system instability due to the geometrical center distance and the rotary center distance are not coincident when the eccentric gears meshing

it can be eliminated by changed single gear into double gear superimposed dislocation

and through virtual simulation results show that the improved device can solve the movement of the instability problem due to backlash better.
