Description

Technical Field

[0001] This utility model relates to the field of moving roller technology, and in particular to a lubricating oil filling structure for a rotating bearing of a fixed-axis moving roller. Background Technology

[0002] Fixed-axis rotating roller structure is commonly found in industrial roller conveyors, rolling mill equipment, paper machine roller groups, etc. During operation, the roller body moves in a circle around a fixed axis. The relative rotation between the shaft and the roller is achieved through bearings. The bearing lubricating oil forms an oil film between the bearing balls, raceways and cage, which converts the dry friction between metals into liquid friction, reduces the coefficient of friction, reduces wear, and removes the heat generated by the bearing operation, preventing the bearing temperature from becoming too high due to frictional heat generation.

[0003] However, some traditional lubrication methods are limited to a single type and cannot lubricate multiple bearings, affecting work efficiency. Furthermore, during lubrication, lubricating oil can slip and cause a messy work area. Residual lubricating oil can solidify at high temperatures and is difficult to clean. There is a lack of real-time monitoring of bearing operating conditions and automatic adjustment of lubrication parameters, relying on manual inspection and experience-based judgment, which can easily lead to missed inspections and over-lubrication. Currently, the market uses triaxial acceleration and vibration sensors installed in key areas of the bearing housing to collect data such as vibration frequency and amplitude in real time. When a bearing wears due to insufficient lubrication, the system can determine the lubrication status based on this data. However, some single-bearing methods still cannot solve this problem, affecting production efficiency. Additionally, manual cleaning is time-consuming and labor-intensive, and cannot be performed frequently, further impacting production efficiency. Utility Model Content

[0039] Working principle: First, the bearing is placed on the roller body 10 and fixed by the gap between the fixed block 11 on the roller body 10 and the bearing. Then, the bearing is further fixed by the support column 12. The work frame 3 on the top of the base 1 serves as support. Then, the drive box 4 is on the left side of the work frame 3, and the motor 6 is inside the protective shell 5 on the left side of the drive box 4. At this time, it is only necessary to start the motor 6. The rotation of the motor 6 drives the gear 7 to rotate. Then, the chain 8 makes the gear 7 on the other side also rotate. There are rotating shafts 9 on the outer wall of both gears 7. When the gears 7 rotate, the two rotating shafts 9 rotate accordingly, so that the roller body 10 on the outer wall of the rotating shaft 9 also rotates, thereby driving the bearing to rotate. Since there are two roller bodies 10, multiple bearings can be lubricated, saving production time and improving efficiency.

[0040] When adding lubricating oil, some lubricating oil will fall due to gravity. At this time, the motor 202 inside the outer casing 201 can be started. The rotation of the motor 202 causes the rotating shaft 203 to rotate. Since there are gears 204 at the top and bottom of multiple rotating shafts 203, and multiple gears 204 are connected by a chain 205, when the rotating shaft 203 rotates, the gears 204 rotate synchronously, which drives the moving plate 206 to move. When the lubricating oil falls, it will fall into the oil storage groove 207 on the surface of the moving plate 206. The bottom left side of the base 1 has an oil outlet groove 208. When the moving plate 206 moves to the oil outlet groove 208, it is rotating downwards, causing the lubricating oil in the oil storage groove 207 to slide into the oil outlet groove 208 due to gravity, and finally be collected by the oil inlet groove 209.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
