In this work a study about the use of four mathematical-computational nontraditional tools with detection purpose and automatic classification of assembly and manufacturing defects in automotive gearboxes from vibration signals is presented. Due to the State of the gear meshing to be characterized by amplitude and phase modulations, two demodulation techiniques are considered. The demodulation of the amplitude and phase of the gear meshing signals using least squares and decomposition by Generalized S Transform, in the wich are used Windows that are adjusted to the characteristics of signafs modulation. The other two approaches, take into account the amplitude of the gear meshing frequencies and their lateral bands. In one, statistical tool...
