Title:
WORKING MACHINE BEARING QUALITY DETERMINING METHOD AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/063435
Kind Code:
A1
Abstract:
[Problem] To enable the quality of a bearing to be determined accurately using a simple process and configuration. [Solution] This method includes: a step for detecting rotational vibration of a bearing; a step for obtaining a vibration frequency by analyzing the rotational vibration by means of Fourier series expansion; a step for dividing the vibration frequency into a total SRF and a residual frequency; and a step for determining the quality of the bearing by comparing the total SRF and the residual frequency.
