| Résumé: | It is known that supported ball bearings have great effects on the vibrations of the gear transmission system,
above in all the presence of local faults as well as the crack growths. For this purpose, this paper focuses on shock
and vibration crack growth diagnostic of ball bearing using vibration analysis. Our work is devoted first to a
study the static behaviour of the ball bearing by determining the stress, strain and displacement, then its dynamic
behaviour by determining the first four natural frequencies. Secondly, a dynamic analysis study of the bearing
was carried with defects as a function of crack size and location. The obtained results clearly show that the
natural frequencies decrease in a non-linear way with the growth of the length of the crack, on the other hand the
stress increases with the presence of the singular points of the crack. Finally, this residual decrease in natural
frequencies can be used as an indicator of the state of failure, as well as a parameter used for the diagnosis and
screening, and to highlight the fatigue life of the bearing |
