Abstract

Abstract

It is urgently necessary to measure and analyze the dynamic transmission error signals of a high-speed gear. The paper constructs a dynamic transmission error measurement system, from which the error curve is obtained and then the error curve is analyzed with the Hilbert-Huang Transform(HHT). The intrinsic mode functions of different frequency components of the dynamic transmission error signal is adaptively gained. Then we separate the axis frequency spectrum and tooth frequency spectrum and obtain the Hilbert spectrum of the error signal. To verify the feasibility and correctness of the error analysis method based on the HHT, we use the Fast Fourier Transform (FFT) to analyze the same transmission error signal. The analysis results show that the HHT is good at frequency spectrum division and filtering of the dynamic transmission error signal of high-speed gear. Compared with the FFT, it can accurately separate the frequency spectra of the transmission error signal, thus having more accurate analysis.
