Sensitivity of Bearings to Vibration: Its Effect on Ultrasonic Waves, Its Effect on Bearing Life

Abstract

High vibrations caused by various factors in the bearing of a car is a common problem in the automotive industry. Nowadays, the issue of reducing excess vibrations that cause bearing failure in industry has been considered by engineers and industry owners. By examining these vibrations and controlling the vibrations in the cars, it will increase the bearing life and reduce the number of out-of-program stops. The experiments were performed using experiments and technologies such as ultrasound, each of which, depending on its inherent characteristics, will have a variety of effects on all components tested. In this paper, by performing various calculations and tests on bearings used in automobiles and investigations such as the effects of vibrations on bearings, the effect of oil viscosity on bearings vibrations, the effect of ultrasonic waves on bearings. And then, using a relative graph, discuss their effects on the bearings. Calculations and tests performed on the bearing were performed by applying the effect of weight and without the effect of weight, the amount of vibration and oscillation was obtained according to the diagram. Then, the effect of increasing the oil temperature for vibrations was presented by a diagram, according to which we can find an increase or decrease in vibrations in the bearing. With the help of these tests, it saves a lot of costs in repairing and maintaining machines, and increases the reliability of machines, and the use of this test reduces noise pollution and increases the quality of bearings in the industry.
