Peeling growth analysis method and peeling growth analysis device for raceway rings of rolling bearings

摘要

The relationship between the elapsed time and the shape of the peeling part can be predicted based on the progress rate of peeling after the occurrence of minute peeling, and the peeling progress analysis of the bearing ring of the rolling bearing that enables bearing replacement at an appropriate timing. A method and a peeling progress analyzer are provided. The step of acquiring the presence / absence and shape of the peeling portion (15) of the raceway ring (11) by the peeling acquisition means (21), and at least the shape of the acquired peeling portion, the specifications of the rolling bearing (10), and the rolling bearing. Based on the operating conditions, the step of calculating the rolling element load F acting on the rolling element when the rolling element (13) passes through the outlet portion (15a) of the peeling portion of the raceway ring, and the exit portion of the peeling portion. The relationship between the step of calculating the extension speed V of the peeling portion considering the shape of the advancing peeling portion based on the rolling element load F and the elapsed time of the rolling bearing and the peeling shape based on the traveling speed V of the peeling portion. It is provided with a step of calculating.
