摘　　要：目前行星齿轮箱已经在军用和民用装备中广泛应用,研究行星齿轮箱的故障诊断方法意义重大。为了研究行星齿轮传动的故障机理,揭示其故障特征,本文建立了行星齿轮系统的动力学模型,研究了齿轮裂纹对齿轮啮合刚度的影响,得出了齿轮正常、太阳轮裂纹和行星轮裂纹等三种状态下系统的频率特征,总结了故障特征频率;最后试验验证了仿真结果的有效性,得出的故障特征频率可用于行星轮系的故障诊断。Nowadays planetary gearboxes have been widely used in military and civilian equipment.Study on fault diagnosis of planetary gearboxes is of important significance.In this paper,a dynamic model of the planetary gear transmission is built to study its fault mechanism and characteristics.The influence of the crack on the meshing stiffness is analyzed.The fault characteristic frequencies are studied under the three conditions,namely normal gear,cracked solar gear and cracked planet gear.Finally,the crack fault experiment is carried out on a test rig,and the results are employed to verify the correctness and effectiveness of the fault detection simulation.The provided feature frequencies can be applied to the fault diagnoses of planetary gear systems.
