| Abstract: | The methods of spectrum analysis are discussed.The transmission error of the gear hobbing machine Y38A has been analysed by means of the FFT algorithm and its Fourier spectrum has been obtained.The analysis result indicates,that the Fourier spectrum is in keeping with the running frequency of the transmission elements. |
