摘　　要：为了分析行星减速器的断齿故障振动特性,文中以某精密斜齿行星减速器为研究对象,将齿圈和断齿部件柔性化处理,使用Abaqus和ADAMS分别建立了正常状态和行星轮、太阳轮、齿圈断齿故障状态下的刚柔耦合动力学模型,进而获取了齿圈上振动加速度信号,并与实验采集的振动加速度信号进行对比,仿真信号与实验信号的吻合度较高。分析结果表明:在时域上,行星减速器发生断齿故障时振动信号的振幅和RMS值均会增大,太阳轮断齿的影响相较于行星轮和齿圈断齿更加显著;在频域上,行星减速器振动信号中包含以啮合频率及其倍频为中心的边频成分,并存在行星架转频和齿轮故障特征频率对振动信号的调制作用。To analyze the vibration characteristics of the planetary reducer with broken teeth,a precision helical planetary reducer was taken as the research object,and the gear ring and the broken teeth were flexibly treated.The rigid-flexible coupling dynamic models of the normal state and the planetary gear,sun gear and gear ring with broken teeth were established by using Abaqus and ADAMS respectively,and then the vibration acceleration signals on the gear ring were obtained,and compared with the vibration acceleration signals collected by experiments.It is proved that simulation signals are highly consistent with experimental signals.The analysis results show that in the time domain,the amplitude and RMS value of vibration signal will increase when the planetary reducer has broken teeth.Compared with the broken teeth of planetary gear and ring gear,the influence of sun gear tooth is more significant.In frequency domain,the vibration signal of planetary reducer contains side frequency components centered on meshing frequency and its frequency multiplication,and planetary carrier rotation frequency and gear fault characteristic frequency play a modulating role in vibration signals.
