Abstract
The matting of gears can be considered one of the most complicated faults to diagnose because its vibratory signature is not really known. In addition, the integration of cracks in digital models is not a simple task. On the other hand, the diagnosis of gears can be done in the time domain through statistical method or in the frequency domain through spectral analysis. In this study we made a vibratory analysis on the whole transmission system from raw mill to the Hamma bouzien-constantine cement plant, and then we compared these results with a numerical model. The numerical results found are very close to the experimental one. The experimental study was carried out by the OMNITREND processing software and the numerical simulation by ansys workbench.
