Abstract: Aiming at the hybrid gear planetary system transplanting mechanism of rice transplanter which applies the eccentric gear non-circular gear planetary system, the finite element method was used to apply the corresponding non-circular gear angular velocity and eccentric gear torque to the meshing state simulation model of non-circular gear and eccentric gear. The results showed that when the transplanting mechanism moved under the limit torque state, the maximum contact stress of non-circular gear was between 180~200 MPa, and that of eccentric gear was between 320~420 MPa. The meshing of non-circular gear and eccentric gear was normal, which meets the design requirements.
