Description

Technical Field

[0001] The utility model relates to the technical field of tightness detection devices, in particular to a bearing tightness detection device. Background Art

[0002] Bearing tightness refers to the contact tightness between the contact surfaces of the bearing in the working state. It is usually used to describe the contact state of the bearing, that is, the degree of contact between the contact surfaces. The size of the bearing tightness has an important influence on the operating performance and life of the bearing. The determination of the bearing tightness involves the lubricant inside the bearing and the geometry of the contact surface. When the contact tightness between the bearing contact surfaces is appropriate, a complete lubrication film can be formed, reducing friction and wear, and maintaining the normal operation of the bearing. Too low or too high bearing tightness may lead to poor lubrication, increase bearing friction and wear, and reduce the life of the bearing.

[0003] The prior art provides a bearing detection device (Announcement No.: CN220473533U), which comprises a bottom plate and a first connecting plate, a fixing frame installed on the bottom plate, a conveyor belt arranged on the inner side of the fixing frame, a bearing member movably connected to the conveyor belt, an outer support clamp connected to the inner side of the bearing member, a second telescopic rod installed on the bottom side of the outer support clamp, a second connecting plate welded and installed on one side of the first connecting plate, a first telescopic rod arranged on the second connecting plate, a support frame arranged on the output end of the first telescopic rod, a driving wheel arranged on one side of the support frame, and a detector arranged on the outer side of the driving wheel.
