Measurement method of torsional vibration signal to extract gear meshing characteristics [PDF]

Journal of Vibroengineering, 2018
A technique in measuring torsional vibration signal based on an optical encoder and a discrete wavelet transform is proposed for the extraction of gear meshing characteristics. The method measures the rotation angles of the input and output shafts of a gear pair by using two optical encoders and obtains the time interval sequences of the two shafts. By
