INSPECTING METHOD OF LUBRICANT APPLYING STATE ON ROLLING BEARING AND INSPECTING DEVICE THEREFOR

摘要

PROBLEM TO BE SOLVED: To inspect whether a lubricant is applied or not when the lubricant is injected only to the inside of a rolling bearing by optically detecting the applying state of the lubricant. SOLUTION: This device is for inspecting whether a specific quantity of the lubricant is discharged from a lubricant discharge device for injecting the lubricant to the inside of the rolling bearing 4 or not. Whether the lubricant is applied or not to the rolling bearing 4 is inspected based on the output from a light receiving element 16 by irradiating a part between a discharge port 6 of the lubricant discharge device and the rolling bearing 4 with laser beam L1 and receiving the reflected laser beam L2, reflected from the lubricant at the time of discharging the lubricant from the discharge port 6, by the light receiving element 16 arranged on an optical axis of the reflected laser beam L2.
