The present paper proposes a synchronization method of a neural oscillator to a meshing frequency of the vibration signal from a gear pair. The proposed method could enable the angular position of the meshing gear to be estimated without any help of speed sensors. The neural oscillator is designed to tune its natural frequency to the meshing frequency of a gear pair, and the acceleration responses, which are measured at the top of the bearing housing, are input to the neural oscillator. Although, the vibration caused by the tooth-to-tooth meshing of a rotating gear pair contains various frequency components, the properly-designed neural oscillator can follow the change in meshing frequency due to the driving torque variation autonomously, because of the synchronization property of the oscillator. The proposed method was applied to the experimental acceleration response in operating tests on POM (Polyoxymethylene) gears. As a result of the application, the meshing periods of the vibration signal was extracted.
