概要
This study evaluates the outer race defect size of ball bearings in the accelerated life test by analyzing the signal of electromagnetic sensor. The electromagnetic sensor consists of a permanent magnet and a pickup coil. When a conductor passes in the static magnetic field, the generated eddy current is detected as the change of the magnetic field. The autocorrelatio n method is applied for sizing defects in the early phase of the damage progress and the RMS method is developed for bigger defects. With those methods, the damage progress is visualized and the characteristic of it is revealed as almost linear. fied for sizing defects in the early phase of the damage ger defects. With those methods, the damage progress is most linear.
