Abstract

Bearings are used in many rotary machines. Defects in them can cause car breakdowns, loss of production, and even catastrophic accidents. This makes them difficult to maintain and will make it costly to repair and maintain. Therefore, detecting defects in bearing vibrations is an important issue for the industry. On the other hand, error-related frequencies may be identified as discrete frequency lines, and therefore error characteristics cannot be easily identified.For this purpose, the axis rotation speed must be identified and then the desired defect can be identified by selecting the frequency by non-destructive testing and ultrasonic testing. In experimental work, this can be done by normal probes. By performing experimental tests, it is necessary to obtain information about the rotation speed by this test. Vibrations in the bearing cause signals that indicate a defect in the bearing.
