DIAGNOSTIC SYSTEM FOR BEARING

摘要

The present invention relates to a bearing diagnostic system capable of discriminating damage to a bearing and the damaged portion of the bearing by sensing vibration due to the rotation of the bearing. A bearing diagnostic system according to an embodiment of the present invention includes a carrying-in unit successively transferring stacked bearings; a test unit rotating the bearings received from the carrying-in unit and sensing the vibration generated by the rotation of the bearings; a control unit computing a reference characteristic frequency according to the number of the rotation of the bearing, converting the vibration sensed by the test unit into a measurement characteristic frequency, and determining whether the bearing is faulty or not by comparing the measurement characteristic frequency with the reference characteristic frequency; and a carrying-out unit receiving the information on whether the bearing is faulty or not from the control unit to sort the tested bearings into normal bearings and faulty bearings and carrying out the bearings.
