摘要

PROBLEM TO BE SOLVED: To provide a measuring method capable of measuring the abrasion quantity of a bearing simultaneously during operation with high reliability.;SOLUTION: An eddy current is generated by an eddy current sensor 12 to a dummy measuring body 13 comprising an electromagnetic induction body and having the surface area reducing by abrading integrally with a measuring object 11, and the abrasion quantity of the measuring object 11 is measured according to the output change of the eddy current sensor 12 corresponding to area reduction of the dummy measuring body 13.;COPYRIGHT: (C)2005,JPO&NCIPI
