摘　　要：介绍了行星齿轮工作原理,利用非线性有限元方法建立了收割机减速器行星齿轮数学模型,并对其进行了有限元建模。实验结果表明:行星齿轮系统太阳轮齿根处弯曲应力变化符合行星齿轮在实际应用过程中的应力规律,证明了有限元计算的刚度结果是正确的,说明系统具有一定的可靠性。first introduces the working principle of planetary gear,establishes the mathematical model of planetary gear of harvester reducer by using nonlinear finite element method,and carries out finite element modeling.The experimental results show that the change of bending stress at the root of the sun gear of the planetary gear system conforms to the stress law of the planetary gear in the process of practical application,which proves that the stiffness result of the finite element calculation is correct and shows that the system has a certain reliability.
