Fatigue Diagnosis Method for rolling machine element and Fatigue Diagnosis System of rolling machine element

摘要

Problem to be solved: to provide a method and a system capable of grasping the fatigue state before the occurrence of damage to the bearing parts, and for diagnosing the fatigue state without disassembling the rolling bearing.Solution: the magnetic flux density in the axial and radial directions of the components is measured by the magnetic sensor disposed in the vicinity of the components without disassembling the rolling element elements, and the amount of change from the reference magnetic flux density corresponding to the magnetic flux density before the start of use of the components is calculated. The degree of fatigue progression of the rolling element is determined from the change amount.Selection diagram
