LUBRICANT DETERIORATION DETECTING DEVICE AND ROLLING DEVICE COMPRISING THE SAME

摘要

PROBLEM TO BE SOLVED: To constantly detect a deterioration condition of the lubricant in a rolling bearing. SOLUTION: A measuring instrument 1 is mounted on an outer ring (fixed ring) 3 of the rolling bearing. At least one of volume resistivity, dielectric constant and dielectric dissipation factor of the lubricant in the rolling bearing is measured by the measuring instrument 1. COPYRIGHT: (C)2003,JPO
