WEAR PARTICLES CAPTURING DEVICE, METHOD OF DIAGNOSING LUBRICATION OBJECT PART, AND LUBRICATION OBJECT PART DIAGNOSTIC SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a lubrication object part diagnostic system which can accurately and quickly diagnose the lubrication state and the wear state of a lubrication object part. SOLUTION: The system 1 includes a wear particle capturing device A which stably captures wear particles in lubrication oil in a short time, on a transparent plate 20 by centrifugal force and magnetic force, an optical microscope B for imaging the wear particles captured on the plate 20, and a computer C which calculates a covering rate and an abnormal friction index of the wear particles by data obtained by binarizing the taken image. According to the system 1, by the computer C, each calculated value is compared with each reference value stored in advance, and the state of the lubrication object part is diagnosed. The diagnostic result is outputted and displayed on a display monitor 8. COPYRIGHT: (C)2004,JPO
