Description

Technical Field

[0001] The utility model relates to the technical field of rolling bearings, in particular to a rolling bearing fault monitoring device. Background Art

[0002] Rolling bearings, also known as rollers, are precision mechanical components. Their main function is to convert the sliding friction between the rotating shaft and the shaft seat into rolling friction, thereby reducing friction losses. Rolling bearings generally consist of four parts: an inner ring, an outer ring, rolling elements and a cage.

[0003] When the existing fault monitoring device is not in use, it is not convenient to provide good protection for the display screen thereon, which easily causes a large amount of external dust to adhere to the display screen. At the same time, since the display screen is directly exposed to the outside, it is easy to cause the display screen to be damaged when it is subjected to external pressure and impact, thereby reducing its own practicality. Based on these problems, Chinese patent CN217331610U discloses a rolling bearing fault monitoring device, which is provided with a cover plate, which covers the outer side of the display screen, so that the display screen can be protected to a certain extent when the fault detector is not needed. At the same time, the movable shaft can be pulled to rotate under the action of the pull rope by the movement of the moving rod, and the cover plate can be rotated and opened by the rotation of the movable shaft, thereby facilitating the normal viewing of the detection data displayed on the display screen.

[0004] When monitoring rolling bearing failures, workers are required to hold the device and check multiple rolling bearings one by one. This process not only wastes the workers' time and energy, but also may result in monitoring omissions, seriously affecting the safety of rolling bearings during use. Utility Model Content
