Investigation of Deep Groove Ball- Bearing Vibration Behavior & Effect of the Bearing Life

Abstract

Investigation of Mechanical systems like Lathes, Motors, Pumps, Turbines, and Engines are the rotating machines are relying. Misalignment, unbalance, rotor cracks and rotor rubs, all the measurements are done at the bearing locations. Earlier bearings themselves having so many rotating elements, they themselves could be defective. This is the main cause for only bearing system consideration by neglecting the other parameters. Anti-friction bearings are the elements that will allow or transmits the motion with smoothness. Finding the defects in the bearing is very difficult sometimes. Present work includes how the rise of vibration will affect the bearing life and also how could fault will be initiated with corresponding to load at the constant speed. SKF 6024 Bearing is considered for this work and Experimentation has been done by varying the load radially from zero to maximum constant speed. The outer race is fixed in this work and carried the dynamic loading with the help of a hydraulic press. The data has been captured by CSI Emerson device and found the fault root cause with the help of Fast Fourier transformation in frequency domain analysis.
