DETERIORATION DETECTOR OF LUBRICANT AND BEARING WITH SENSOR

摘要

PROBLEM TO BE SOLVED: To provide a deteriorating detector of a lubricant easily installed in the detection part of the inside of a bearing or the like and capable of stably and precisely detecting the deterioration state of the lubricant without being affected by the thickness or dust/air bubble of the lubricant even in a case that the lubricant is widely distributed. SOLUTION: In the deteriorating detector 1 of the lubricant, a transparent detection member 3 having an uneven shape on its surface is provided on the imaging surface of an area imaging element 4 capable of photographing a planar area. The uneven surface of the detection member 3 is set to the arrangement surface of the lubricant 6 being a measuring target and a light source 2 for projecting light is provided in opposed relation to the detection member 3. A judge means 5 for measuring the intensity of detection light corresponding to the uneven shape of the detection member 3 from the output of the area imaging element 4 to judge the deterioration degree of the lubricant 6 is provided.
