Adaptive Wavelet Transform Method to Identify Cracks in Gears
<p/> <p>Many damages and faults can cause problems in gear unit operation. A crack in the tooth root is probably the least desirable among them. It often leads to failure of gear unit operation. By monitoring vibrations, it is possible to determine the presence of a crack. Signals are, h...
