摘　　要：针对将偏心齿轮-非圆齿轮行星系应用于插秧机的混合齿轮行星系分插机构,运用有限元方法对非圆齿轮与偏心齿轮啮合状态仿真模型施加相应的非圆齿轮角速度和偏心齿轮转矩。结果表明,分插机构在极限转矩状态下运动时,非圆齿轮最大接触应力在180~200 MPa,偏心齿轮最大接触应力在320~420 MPa,非圆齿轮与偏心齿轮啮合正常,符合设计要求。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.
