INSPECTING THE QUALITY OF SEPARATORS OF ROLLING BEARINGS OF MOVING ROLLING STOCK

An ultrasound method of inspecting separators of rolling bearing using electromagnetic acoustic transducers is proposed. The directionality diagram and sensitivity of transducers are determined and the method of inspecting connectors of a separator by the echo-pulsed and mirror-shadow techniques is described. A flaw detector was developed and produced for detecting internal microcracks and also determining the degree of aging the metal in which these components were made.
