Vibration Based Diagnosis for Planetary Gearboxes Using an Analytical Model by Liu Hong, Yongzhi Qu, Yuegang Tan, Mingyao Liu, Zude Zhou

“…The application of conventional vibration based diagnostic techniques to planetary gearboxes is a challenge because of the complexity of frequency components in the measured spectrum, which is the result of relative motions between the rotary planets and the fixed accelerometer. In practice, since the fault signatures are usually contaminated by noises and vibrations from other mechanical components of gearboxes, the diagnostic efficacy may further deteriorate. …”
