Description

Technical Field

[0001] This utility model relates to the field of hot rolling mills, and more particularly to bearings for hot rolling leveling machines. Background Technology

[0002] A hot rolling mill is a device used for leveling metal materials such as steel and aluminum after hot rolling. It mainly consists of a series of rollers. Through the rotation and pressure of the rollers, the surface of the metal sheet is smoothed to achieve uniform dimensions. Hot rolling mills play a crucial role in steel manufacturing, ensuring the surface quality and dimensional accuracy of the steel. Bearings are a very important component of hot rolling mills, mainly used to support the rollers, reduce friction during roller rotation, and ensure smooth operation.

[0003] In the process of realizing this application, the inventors discovered the following problems with the prior art: In conventional hot rolling mills, lubricating oil needs to be added to the rollers, but the lubricating oil will be consumed or lost in a short time, which requires the staff to constantly monitor the lubrication status and manually replenish the lubricating oil. This not only increases the frequency of maintenance work and labor costs, but also requires the equipment to be stopped during the oil replenishment process, causing the production line to stop and affecting the overall production efficiency.

[0004] Therefore, those skilled in the art have provided bearings for hot rolling leveling machines to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a bearing for a hot rolling leveling machine. After lubricating oil is added to the oil inlet, the lubricating oil in the oil reservoir will continuously seep out, ensuring that the rollers are fully lubricated, reducing friction and wear, thereby improving work efficiency and reducing maintenance frequency.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A bearing for a hot rolling leveling machine includes a cage, an inner ring, and a plastic oil body. The inner wall of the cage has an oil storage groove. Sealing plates are fixed to the upper and lower sides of the cage by bolts. The inner ends of the two sealing plates have sliding grooves. The upper end of the cage has multiple oil inlets. The inner end of the cage has multiple oil seepage holes. The outer end of the cage has multiple rollers that are rotatably mounted.

[0008] Limiting plates are fixed to the upper and lower sides of the inner ring by bolts. Slider blocks are fixed to the outer ends of the two limiting plates. Multiple mounting holes are opened at the inner end of the inner ring. The plastic oil is injected into the gap and surface of the assembled roller and cage by injection molding process.

[0009] Furthermore, the two oil inlets are connected to the oil storage tank, and the oil storage tank is connected to multiple oil seepage holes.

[0010] Furthermore, the two oil inlets are located at the lower end of one of the two sealing plates, and the two sliders are respectively slidably disposed at the inner ends of the two grooves.

[0011] Furthermore, the multiple rollers are rotatably arranged between each pair of multiple oil seepage holes, and the inner ring is placed inside the cage.

[0012] Furthermore, the plurality of rollers contact the outer wall of the inner ring.

[0013] Furthermore, the cage is made of low-carbon steel.

[0014] This utility model has the following beneficial effects:

[0015] The bearing for a hot rolling mill proposed in this invention allows for continuous seepage of lubricating oil from the oil reservoir after lubricating oil is added to the oil inlet, ensuring sufficient lubrication of the rollers, reducing friction and wear, thereby improving work efficiency and reducing maintenance frequency. The sealing plate effectively prevents lubricating oil leakage from the oil inlet, ensuring the sealing and reliability of the lubrication system and extending the bearing's service life.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 1-7 One embodiment provided by this utility model:

[0027] The bearing for a hot rolling leveling machine includes a cage 1, an inner ring 3, and a plastic oil reservoir. The inner wall of the cage 1 has an oil reservoir 2. Sealing plates 5 are bolted to both the upper and lower sides of the cage 1. Sliding grooves 10 are formed at the inner ends of the two sealing plates 5. Multiple oil inlets 11 are formed at the upper end of the cage 1. Multiple oil leakage holes 6 are formed at the inner end of the cage 1. Multiple rollers 8 are rotatably mounted on the outer end of the cage 1. Limiting plates 4 are bolted to both the upper and lower sides of the inner ring 3. Sliding blocks 9 are fixed to the outer ends of the two limiting plates 4. The inner end of the inner ring 3... Multiple mounting holes 7 are provided. Plastic oil is injected into the gap and surface of the assembled roller 8 and cage 1 through injection molding process. Multiple oil inlets 11 are connected to the oil storage tank 2. The oil storage tank 2 is connected to multiple oil leakage holes 6. Multiple oil inlets 11 are located at the lower end of one of the two sealing plates 5. Two sliders 9 are respectively slidably set in the inner end of the two slide grooves 10. Multiple rollers 8 are rotatably set between each pair of multiple oil leakage holes 6. The inner ring 3 is placed in the inner end of the cage 1. Multiple rollers 8 are in contact with the outer wall of the inner ring 3. The cage 1 is made of low carbon steel.

[0028] In this invention, the plastic oil is injected into the gap and surface between the assembled roller 8 and the cage 1 through an injection molding process. This allows the injection-molded plastic oil to provide primary lubrication, and the oil inside the oil reservoir to slowly seep out to provide secondary lubrication. The combination of the two can achieve a better lubrication effect.

[0029] Specifically, when installing this device, first insert the inner ring 3 into the cage 1, then fix the sealing plate 5 to the upper and lower sides of the cage 1 with bolts, and at the same time fix the limiting plate 4 to the upper end of the inner ring 3 with bolts. During the operation of the equipment, the inner ring 3 will start to rotate. Since the outer wall of the inner ring 3 is in contact with the roller 8, the roller 8 can continuously roll outside the cage 1.

[0030] The inner ring 3 is made of wear-resistant material to ensure that the connection part of the inner ring 3 in the hot rolling mill has good wear resistance, effectively reducing the risk of damage caused by friction and wear, thereby reducing maintenance costs and improving production efficiency. At the same time, the presence of the inner ring 3 can protect the cage 1, so that the oil storage tank 2 will not be damaged during the operation of the hot rolling mill.

[0031] After the lubricating oil is added through the oil inlet 11, it will continuously seep out from the oil leakage hole 6 to lubricate the roller 8. The sealing plate 5 can seal the oil inlets 11 on both sides of the cage 1, effectively preventing lubricating oil leakage, thereby ensuring the sealing performance and continuous operation of the lubrication system.

[0032] The outer circumferential surface of roller 8 is precision ground to a surface roughness of ≤0.8μm. The cylindrical roller 8 can withstand a large radial load and is suitable for the high-load working conditions of hot rolling mills. The smooth outer circumferential surface can reduce the frictional resistance with cage 1 and reduce the scraping loss of plastic oil.

[0033] Working Principle: During installation, the inner ring 3 is first inserted into the cage 1. Then, the sealing plate 5 is fixed to the upper and lower sides of the cage 1 with bolts, forming a sealing structure to prevent lubricant leakage. Simultaneously, the limiting plate 4 is also bolted to the upper end of the inner ring 3 to limit the rotation range of the cage 1, thereby reducing wear and improving bearing stability. During operation, the inner ring 3 begins to rotate. Since the outer wall of the inner ring 3 contacts the rollers 8, the rollers 8 can continuously roll outside the cage 1, thus achieving shock absorption and load transfer. At this time, lubricant gradually enters the oil reservoir 2 through the pre-set oil inlet 11. The lubricant in the oil reservoir 2 can continuously seep out through the oil leakage holes 6, evenly covering the rollers 8 along the internal channels, effectively reducing friction and wear. The sealing effect of the sealing plate 5 ensures that lubricant will not leak out of the bearing during operation, preventing lubricant loss.

[0034] 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.
