Vibration data analysis plays a critical part in condition monitoring for fault detection, diagnostics and condition based maintenance (CBM) purposes. This requires development of effective methods for analyzing vibration data. A literature review has shown that while there exists a body of literature on vibration data analysis techniques of gearboxes with fixed-axis gear sets, techniques for gearboxes with planetary gear sets have been explored to a lesser extent. The aim of our research was to develop such a method for analyzing vibration data of planetary gears. In this paper, we compared the raw signal, time synchronous averaged signal, and wavelet transforms with the time synchronous averaged signal. We determined that the methods using wavelet transform can achieve desirable feature extraction for fault detection, diagnostics and CBM purposes.
