齿轮传动的动态性能和许多因素有关,情况是非常复杂的.本文分析了齿轮传动的频率特性和它所产生的频率和幅值调制信号.利用倒频谱技术可以区分齿轮箱中不同转速的齿轮所产生的振动信号;同时倒频谱不会受信号传递通道和相位所影响.因此倒频谱是分析齿轮缺陷的有效工具.本文并介绍了作者研制的倒频谱分析软件.
The dynamic performance of gear drive is related to many factors, and the situation is very complicated.This paper analyzes the frequency characteristics of gear drive and the frequency and amplitude modulation signal that it produces.Using cepstral spectrum technology can distinguish the gears with different speed in gearbox And the cepstrum is not affected by the signal transmission channel and phase, so the cepstrum is an effective tool to analyze the gear defects.This paper also introduces the cepstrum analysis software developed by the author.
