Investigation on Effect of defect on Cylindrical Roller Bearing by Experimental and FEA approach

Abstract — Rolling element bearings are commonly used components in machinery for a wide range of applications. This work represents investigation of performance of cylindrical roller bearing. In this work lateral defect on outer race is focused and size of defect is varied during experimentation. Radial load and RPM are varied within specified range and experimental vibration signals were obtained. Vibration signals analysis has been carried out in time domain by FFT analyzer. Results of experimentation were benchmarked by using Finite Element Analysis using ANSYS. Results show that as defect size and RPM increases there are sudden increase in amplitude of vibration up to 1500 RPM. There is 51%of increase was observed in amplitude of vibration at 1500 rpm in defective bearing as compared to healthy bearing The actual measurements of vibration signals for healthy, defective bearing has been carried out by using FFT analyzer and time domain signal analysis has been done in comparative manner
