摘　　要：基于带有时频倾斜算子的Gabor小波变换册,提出了时频线性倾斜Gabor小波变换册功率谱方法,用该方法进行了齿轮故障诊断的试验验证。试验结果表明,该方法可提取反映齿轮故障模式的边频带结构,且提取的边频结构更加清晰,适用于齿轮的局部故障诊断,具有一定的应用价值。Based on the method of gabor wavelet transform with time and frequency inclining operator,a new method of spectra estimation of gabor wavelet transform for fault diagnosis of gears is presented in this paper.The method is verified by tests for diagnosis of gears.The result indicates that the method can highlight the side-bang configuration of gear and it is applicable to the local fault diagnosis of gear.
