摘要: 采用连续小波变换对齿轮振动信号进行分析,检测到齿轮出现局部缺陷时,其振动信号中的幅值突变点。通过对试验数据的分析,说明这种方法可以有效地应用于齿轮的局部缺陷诊断中,并且不需要对初始信号进行时域同步平均。

Abstract: Wavelet transform is applied to vibration signal analysis of gears to detect the meshing abnormality of gears with local defects. Results of experiment show that the method can be applied to local defect detection of gears successfully, and time-domain average is not needed as conventional approaches usually need.

Key words: Gear Fault detection, Wavelet transform
