Incipient Fault Detection in Roller Bearing Using Ultrasonic Diagnostic Technique

摘要: Rolling element bearings are extensively used in machinery to transmit rolling/sliding motion. These machine elements prone get damaged due an increase friction, which causes the heat generation and gradual wear on rolling contact surfaces of bearing. Bearing failure leads unexpected shutdown machinery. Therefore, many condition monitoring methods have been developed predict bearing faults. The ultrasonic flaw detection method is one promising techniques detect This paper describes application incipient faults roller subjected fatigue load cycles. Results highlighted suitability identify that appeared surfaces.
