Analysis method and delamination propagation analysis method of delamination propagation for rolling bearing

摘要

Problem to be solved: to predict the relationship between the elapsed time and the shape of the separation portion on the basis of the progress speed of the delamination after the occurrence of minute delamination, and to provide a method for analyzing the delamination propagation and the delamination propagation analysis of the raceway wheel of the rolling bearing capable of changing the bearing at the appropriate timing.A method for obtaining the presence or absence of a delamination portion of the orbiting wheel by means of a delamination acquisition means and a method of obtaining a shapeAt least the shape of the obtained delaminationDimensions of rolling bearingsBased on the operating conditions of rolling bearingsWhen the rolling body passes through the outlet of the delamination of the orbital wheelThe process of calculating the rolling element load f acting on the rolling body and the followingBased on the rolling element load f at the outlet of the delaminationThe step of calculating the propagation velocity V of the delamination portion in consideration of the shape of the advancing separation portion and the followingBased on the propagation velocity V of the delaminationHow to calculate the relationship between the elapsed time and the delamination shape of rolling bearings.Diagram
