| Résumé | Shock pulse monitoring and ferrography are recent techniques for detecting wear or damage in machine elements. Shock pulse monitoring is an on-line technique which can continuously monitor the health of rolling element bearings in a machine. The shock pulse technique detects stress waves or "shock pulses" which are propagated through the metal housing of a machine when one part of a bearing collides with a defect in another bearing segment, for example, when a ball or roller impacts a spall in one of the bearing races. The pulses are detected by a sharply-filtered, high frequency detector and the severity of the defect is inferred from the amplitude of the pulses. The filtering and the high frequency of detection combine to make the transducer insensitive to normal machine vibrations. |
