摘要
断齿是行星齿轮箱常见的一种故障形式。当行星齿轮箱发生断齿故障时,传感器采集到的振动信号由于传递路径的影响会变得复杂,给故障诊断带来困难。为了研究行星齿轮箱发生断齿故障时传递路径对频谱结构的影响,在Adams仿真平台中分别建立行星齿轮箱无故障、太阳轮断齿故障、行星轮断齿故障及齿圈断齿故障的刚柔耦合模型并进行仿真,提取分析了系统不同状态下箱体的振动仿真信号。结果表明,在时域波形中,路径的变化会对箱体固定位置测量点处的振动信号产生明显的调幅作用;在频谱图中,啮合频率的两侧也会产生由不同频率组合的边带成分。该研究可为后续行星齿轮箱的故障诊断提供依据和参考。
Tooth break is a common fault which always occurs in the planetary gearboxes,and when it occurs,due to the influence of transmission path,the vibration signal collected by the sensor becomes complicated,which brings difficulties to fault diagnosis.Thus,in order to study the influence of transmission path on spectrum structure of planetary gearboxes with tooth break fault,the rigid-flexible coupling models with no fault,sun gear tooth break fault,planet gear tooth break fault and ring gear tooth break fault of planetary gearboxes are established on Adams,and the vibration signals of the box body are extracted and analyzed by simulation.The simulation results show that:in the time-domain,the change of the path will have an obvious amplitude modulation on the vibration signal which is measured at a fixed point of the box.What’s more,in the spectrum diagram,the two sides of the meshing frequency will also produce side bands composed of different frequencies.This study can provide basis and reference for fault diagnosis of planetary gearboxes in the future.
