摘要：

The authors set forth a fault information enhancing method based on fault diagnosis of armored gearbox. The method is supposed to obtain periodic signal by means of time-domain average technique, to obtain axis frequency and mesh frequency signals by conducting demodulation analysis, re-sample and time-domain average. In the process of studying characteristics of fault signals, fault information enhancing technology is employed and the fault sensitive factors are worked out. The result is proved to be right and effective through analyzing the vibration test of gearbox. Compared with the otherwise, this method raises the ratio of signal to noise, and enhances the fault information greatly.
