Abstract：Planetary gearboxes are widely used in wind turbine, aerospace, marine and other large engineering machines. Harsh operation conditions frequently cause faults, such as pitting and fatigue crack to occur in planetary gearboxes. Most reported fault diagnosis methods use time or frequency domain information. But the general signal processing methods are not effective for planetary gearboxes due to the complexity of vibration signals as well as combined motions of planetary gears. Based on the analysis of the motion to a sun gear, a planet gear and vibration transmission paths, a new characteristic frequency named tidal frequency is proposed as a unique signature for planetary gear system diagnostics. Through experimental signal analysis to the planetary gearbox with a localized fault on the sun gear, it shows the existence of the tide frequency and that the method is effective for planetary gearbox diagnosis.
