<P>PROBLEM TO BE SOLVED: To provide a lubricant degradation detector simply and compactly mountable on a bearing for stably and accurately detecting a state of a degraded lubricant within the bearing. <P>SOLUTION: In the lubricant degradation detector, a light emitting element and a light receiving element are oppositely provided on both ends, respectively, of a circular arc-shaped optical fiber 4, and a gap 7 for measurement is provided in a part of the optical fiber 4 for causing a lubricant 5 to exist therein. Both side portions of this gap 7 are fixed to an apparatus using the degradation detector by means of a fixing tool 11. An actuator 15 for circulating the lubricant 5 in the gap 7 is provided on the fixing tool 11. <P>COPYRIGHT: (C)2009,JPO&INPIT |
