ABSTRACT:
An evaluation method for a rolling bearing part capable of easily and properly detecting deformation of the rolling contact surface of the rolling bearing part formed of raceway rings or rolling element of a rolling bearing. First, the order and amplitude of waviness on the rolling contact surface of the rolling bearing part are obtained by harmonic analysis for the circularity of the rolling contact surface. The order and amplitude of waviness so obtained are logarithmically converted, and the regression line showing a relation between the logarithmically converted order of waviness and the amplitude of waviness is obtained. Based on the deviation from the regression line, the deformation of the rolling contact surface is evaluated.
