Abstract

USGAME SANDOVAL, H. M; PEDRAZA RAMIREZ, C. A  and  QUIROGA MENDEZ, J. E. Acoustic emission-based early fault detection in tapered roller bearings. Ing. Investig. [online]. 2013, vol.33, n.3, pp.5-10. ISSN 0120-5609.

This paper proposes an acoustic emissions-based method for monitoring tapered roller bearings. This method monitors tracking time-based fault indicators (i.e. RMS, peak value, ring-down count and kurtosis) obtained using the AE signal. Experiments were carried out on a dedicated test bench for different levels of tapered roller bearing outer and inner race defect severity. Although the fault indicators studied could not discriminate between outer and inner raceway defects, the experimental results highlighted the proposed indicators' tapered roller bearing fault detection and fault severity assessment ability (i.e. peak value, RMS and ring-down count).

Keywords : acoustic emission; bearing fault detection; bearing monitoring.
