Experimental Test Results on the Effect of Ultrasonic Waves on Defects in Car Bearings: The Effect of Defect Size

Abstract

To check for defects in car bearings, they are identified and measured by sound waves that are affected by the defect. Based on sound, it is called ultrasound technology because it uses high frequencies. High frequencies are the basis of ultrasound. Two features are useful for low-speed cars, which by definition usually have poor signal tolerance. High frequencies are sensitive to the effects of sound waves. In addition, the ultrasound amplitude does not naturally respond to low-frequency phenomena such as machine speed because low frequencies have less wave amplitude. Ultrasound also detects bearing defects in bearings. In the case of low speeds, these effects are very weak because their frequency is very low and causes structural vibration. Ultrasound is a method of choice in this test. A new method of ultrasonic signals was also introduced to investigate faults. This signal then warns the controller to distribute the right amount of lubrication if necessary, as this is contrary to the average performance program. Defects from experimental work have been proposed over time and have been investigated by ultrasonic cracking, single pore defects, and corrosion defects. Here, equipment failure time and maintenance time in the industrial environment are reduced because, with proper diagnosis and examination, these defects can be reduced until the time of progress. All defects were checked with a 10 MHz probe. In this paper, due to the correct diagnosis by ultrasound and assistance to the industry and technical inspection, the cost of equipment failure and maintenance and repair when used in an industrial environment is reduced and the proposed method can be useful. The best corrosion effect was determined for the bearing shell to determine the amount of corroded shell.
