ROLLER BEARING AND FASTENING STATE MONITORING METHOD OF ROLLER BEARING

摘要

PPROBLEM TO BE SOLVED: To provide a roller bearing capable of ensuring a smooth sliding state of a rolling body. PSOLUTION: A self-alignment roller bearing 11 comprises an inner ring 12 formed by fastening two-slit inner ring members 12a, 12b, a spherical roller 14a rolling on track surfaces 18a, 18b of the inner ring 12, and a strain gauge 22a as a sensor arranged across one split inner ring member 12a and the other split inner ring member 12b, sandwiching the split surface of the adjoining split inner ring members 12a, 12b, detecting and outputting a change in an interval between the adjoining split inner ring members 12a, 12b by the change in compression stress.
