technical field

The utility model relates to the technical field of rolling bearings, in particular to a rolling bearing fault monitoring device.

Background technique

Rolling bearings are precision mechanical components that can turn the sliding friction between the running shaft and the shaft seat into rolling friction, thereby reducing friction loss. Therefore, rolling bearings are often used as mechanical components in the field of mechanical engineering. Faults are prone to occur after long-term use. In order to effectively check the faults of the bearings, the corresponding bearing fault detectors are usually used.
