Abstract
This paper is devoted to gear diagnostics using a new technique based on cyclostationary theory. Fonnulation of the method and calculation of the Spectral Correlation Density (SCD) are presented. The Spectral Correlation Function may be seen as a parameter measuring the 'link' between harmonic components. This technique is demonstrated on simulated example, and used to analyse real vibration signals measured on an industrial like gear system. SCD is compared to classical (but powerful) phase modulation technique for the diagnostics of spalling in gear teeth. The results show that SCD may detect this fault in an early stage.
