Technical Field

[0001] This utility model relates to the field of bearings, and in particular to a high-temperature resistant bearing. Background Technology

[0002] A bearing is a mechanical component primarily used to support rotating or moving parts, reducing friction to achieve smooth and efficient movement. It typically consists of an inner ring, an outer ring, rolling elements (such as balls or rollers), and a cage. Through rolling friction, it significantly reduces friction between rotating or sliding parts, minimizing energy loss and improving mechanical efficiency.

[0003] In the process of realizing this application, the inventors discovered the following problems with the prior art: conventional bearings rely on the continuous lubrication of grease or lubricating oil. Insufficient lubrication or aging can lead to increased friction, overheating, or even premature failure. Therefore, regular disassembly, cleaning, oiling, or replacement of lubricating oil is required. These maintenance tasks are cumbersome and time-consuming, increasing manpower and economic costs.

[0004] Therefore, those skilled in the art have provided a high-temperature resistant bearing 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 high-temperature resistant bearing. After storing lubricating oil in the oil storage box, frequent oiling or replacement operations can be reduced. The lubricating oil can continuously and slowly seep out through the oil seepage hole, thereby effectively reducing the frequency of bearing failure.

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

[0007] A high-temperature resistant bearing includes an outer ring, an inner ring, multiple balls, and two sealing caps. Two guide posts are fixedly arranged on both the upper and lower sides of the outer ring. Placement grooves are opened at the upper ends of the outer ring and the inner ring. Sliding grooves are opened at the edges of the upper and lower sides of the inner ring. Sliding plates are fixedly arranged at the edges of opposite sides of the two sealing caps. An oil storage box is fixedly arranged at the lower end of one of the two sealing caps. A plug is threaded onto the upper end of the oil storage box.

[0008] The inner ring includes a wear-resistant layer, a buffer layer is provided at the outer end of the wear-resistant layer, and a connecting layer is provided at the outer end of the buffer layer.

[0009] Furthermore, the two sealing caps are fixedly mounted on the upper and lower sides of the outer ring by bolts, and the inner ring is located at the inner end of the outer ring.

[0010] Furthermore, the two sliding plates are disposed at the inner ends of the two sliding grooves, and the oil storage box is disposed at the inner end of the placement groove.

[0011] Furthermore, the plug is movably mounted on the upper end of one of the two sealing caps, and the lower end of the plug has multiple oil leakage holes.

[0012] Furthermore, each of the two sealing caps has two insertion holes at its upper and lower ends, and the four guide posts are respectively disposed inside the four insertion holes.

[0013] Furthermore, the wear-resistant layer is made of tungsten carbide cemented carbide, and the buffer layer is made of cobalt-based alloy.

[0014] Furthermore, the connecting layer is made of low-alloy high-strength steel.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model proposes a high-temperature resistant bearing that, through the continuous and slow seepage of lubricating oil into the oil seepage holes, significantly reduces friction and wear between the balls and the working area, effectively lowering the frequency of bearing failure and thus extending its service life. Simultaneously, the oil storage box design reduces frequent oiling or replacement operations, lowering maintenance difficulty and overall maintenance costs. After the device is installed, the sealing cap effectively prevents dust and impurities from entering the internal environment, keeping the bearing clean.

[0027] 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.

[0028] Reference Figures 1-6 One embodiment provided by this utility model:

[0029] A high-temperature resistant bearing includes an outer ring 1, an inner ring 2, multiple balls 3, and two sealing caps 10. Two guide posts 7 are fixedly installed on both the upper and lower sides of the outer ring 1. Placement grooves 4 are opened at the upper ends of the outer ring 1 and the inner ring 2. Sliding grooves 8 are opened at the edges of the upper and lower sides of the inner ring 2. Sliding plates 9 are fixedly installed at the edges of the opposite side of the two sealing caps 10. An oil storage box 5 is fixedly installed at the lower end of one of the two sealing caps 10. A plug 6 is threaded on the upper end of the oil storage box 5. The two sealing caps 10 are fixedly installed on the upper and lower sides of the outer ring 1 by bolts. The inner ring 2 is located at the inner end of the outer ring 1. The two sliding plates 9 are located at the inner ends of the two sliding grooves 8. The oil storage box 5 is located at the inner end of the placement groove 4. The plug 6 is movably installed at the upper end of one of the two sealing caps 10. Multiple oil leakage holes are opened at the lower end of the plug 6. Two insertion holes are opened at both the upper and lower ends of the two sealing caps 10. Four guide posts 7 are respectively installed at the inner ends of the four insertion holes.

[0030] Specifically, first, one of the sealing caps 10 is fixed to the lower end of the outer ring 1 with bolts. Then, the sliding groove 8 at the lower end of the inner ring 2 is aligned with the outer end of the sliding plate 9 below the outer ring 1, so that the inner ring 2 and the outer ring 1 can cooperate with each other to form a sliding track. Then, the ball bearing 3 is installed from the placement groove 4. Next, the oil storage box 5 is aligned with the placement groove 4 to ensure that the area of ​​the ball bearing 3 is sealed. Then, the other sealing cap 10 is fixed to the upper end of the outer ring 1 with bolts. At this time, the installation of this device is completed.

[0031] After assembly, after unscrewing the plug 6 at the top of the oil storage box 5, the lubricating oil can be slowly added into the oil storage box 5. The lubricating oil will automatically seep out through the oil seepage hole at the bottom of the oil storage box 5. The lubricating oil flows evenly from the oil seepage hole into the area where the ball 3 is located, thereby lubricating the surface of the ball 3.

[0032] It is important to note that when adding oil to the oil storage box 5, it must be confirmed that the sealing cap 10 is installed to ensure that the lubricating oil can smoothly seep out from the oil seepage hole and flow into the working area of ​​the ball 3. The diameter of the oil seepage hole is <0.5mm to ensure a continuous supply of lubricating oil. The lubricating oil used in this device is a high-temperature resistant perfluoropolyether oil, which has excellent heat resistance and chemical corrosion resistance and can maintain good lubrication effect in high-temperature working environments.

[0033] Reference Figure 7 The inner ring 2 includes a wear-resistant layer 201, a buffer layer 202 is provided at the outer end of the wear-resistant layer 201, and a connecting layer 203 is provided at the outer end of the buffer layer 202. The wear-resistant layer 201 is made of tungsten carbide hard alloy, the buffer layer 202 is made of cobalt-based alloy, and the connecting layer 203 is made of low alloy high-strength steel.

[0034] Specifically, the wear-resistant layer 201 of the inner ring 2 is made of tungsten carbide cemented carbide. Tungsten carbide cemented carbide has extremely high hardness and wear resistance, which can effectively resist wear caused by friction during operation and extend the service life of the bearing.

[0035] The buffer layer 202 is made of cobalt-based alloy. Cobalt-based alloy has good toughness and impact resistance, which can absorb and buffer external impact force, reduce the damage of instantaneous stress to the wear-resistant layer 201, and improve the impact resistance of the overall structure.

[0036] The connecting layer 203 is made of low-alloy high-strength steel. Low-alloy high-strength steel not only has excellent strength and toughness, but also facilitates a firm connection with other structural parts, thereby improving the overall reliability of the inner ring 2.

[0037] High-strength welding technology is used to connect the connecting layer 203, the wear-resistant layer 201 and the buffer layer 202 together. After welding, the bonding between each layer is tight, without micro-cracks and voids, ensuring that the overall structure has excellent mechanical strength and durability and can withstand high-intensity working loads and impact loads.

[0038] Working principle: First, one of the sealing caps 10 is fixed to the lower end of the outer ring 1 with bolts. Then, the sliding groove 8 at the lower end of the inner ring 2 is aligned with the outer end of the sliding plate 9 below the outer ring 1, so that the inner ring 2 and the outer ring 1 can cooperate to form a sliding track. Then, the ball bearing 3 is inserted into the placement groove 4. Next, the oil storage box 5 is aligned with the placement groove 4 to ensure that the area of ​​the ball bearing 3 is sealed. Then, the other sealing cap 10 is fixed to the upper end of the outer ring 1 with bolts. At this time, the installation of this device is completed. After the assembly is completed, the plug 6 at the upper end of the oil storage box 5 is unscrewed, and the lubricating oil can be stored in the oil storage box 5. The lubricating oil will automatically seep out through the oil seepage hole at the lower end of the oil storage box 5, thereby lubricating the surface of the ball bearing 3.

[0039] Secondly, the wear-resistant layer 201 of the inner ring 2 is made of tungsten carbide hard alloy, which can effectively resist wear caused by friction during operation. The buffer layer 202 is made of cobalt-based alloy, which can absorb and buffer external impact forces. The connecting layer 203 is made of low-alloy high-strength steel, which has excellent strength and toughness.

[0040] 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.
