Vibration Analysis of Ball Bearing

Ravindra A.Tarle | Nilesh K.Kharate | Shyam P. Mogal

Abstract: In today-s scenario, maintenance of any machinery is very important in view of downtime of machinery. The bearing sector is one of the examples without which not single rotating machinery work. Products of bearing sector are of high value which leads to the aspects of bearing life & application in more demanding situations. This project addresses Design, Experimentation and Validation analysis of fault diagnosis of ball bearing related to rotor system. Detail analysis using FFT Methodology is done to find out the possible faults and finally validate with MATLAB software. Numbers of faults are identified and this will be validated for each fault. Faults are identified on single rotor system test rig. Experimental Evaluation & validation of faults are done to confirm results and finally effective solution is implemented to completely indicate faults of bearing which are being reported during validation process. In addition to this we have done lubrication analysis by using FFT analyzer for bearing with lack of lubrication and bearing with lubrication.

Keywords: vibration, bearing fault, FFT, Hilbert-Huang Transform, Intrinsic Mode functions, empirical mode decomposition
