Abstract

This paper proposes a systematic framework for the fault detection and condition monitoring of planetary gearbox using internal encoder signal rather than traditional external vibration signal. In this work, the raw encoder signal is firstly converted into instantaneous angular speed signal through difference method. Then comb filtering is applied to remove the interferences and highlight the concerned feature components. Finally, sparsity-based signal decomposition algorithm is introduced to separate the fault transients and harmonic components. With the proposed method, the periodical fault transients are successfully extracted and the weak incipient fault can be effectively detected. Moreover, the validity of the proposed method is confirmed through the synthetic encoder signal and real data acquired from the planetary gearbox.
