Experimental and numerical investigation of defect-size estimation in taper roller bearing

Abstract

In this article, the estimation of different defect sizes present on the outer race of taper roller bearing confirms the effectiveness of the applied method for different vibration signals. Experiments and numerical model conducted for three primary conditions of bearing setting, which are positive, negative, and zero clearance. The outer race is installed in five different positions so that the defect located at 0°, 45°, 90°, 135°, and 180°. The output of the numerical model finds close correlation with the vibration signal pattern-obtained experiments. From the results, it is clear that defect-size estimation is more precise when the defect is introduced in the unloading area, and the contact time depends directly on the size of the defect, through which it is easy to calculate its value of the defect.

Condition Monitoring of Localized Outer Race Defects of Taper Roller Bearings Using Vibration Analysis

“…The obtained results have good consistency with that of the Hertzian theory, [20]. The effect of the displacement of inner race and the friction coefficient on fatigue, wear, penetration and generated Hertzian stress was studied, [21]. The contact stress of large diameter ball bearings was studied using analytical and numerical methods, [22].…”

Survey of Gear Fault Diagnosis Using Various Statistical Signals Parameters

“…The results showed that, the amplitude level of vibration signals was produced from outer race defect is more than that for the inner race defect [13]. FE Dynamic model considers a suitable method used to diagnosis the bearing defects of different sizes in the bearing, [14].…”

Stress Analysis of Gear Pair Faults Using FEM
