[0001] This utility model relates to the field of bearing technology, and in particular to a high-temperature resistant, oil-free lubricated bearing that is easy to disassemble and assemble. Background Technology

[0002] In industrial production, bearings are key transmission components, and their performance directly affects the operational stability and service life of equipment.

[0003] Traditional bearings have many drawbacks for high-temperature, oil-free lubrication conditions: on the one hand, the disassembly and assembly structure of existing high-temperature bearings is complex, and disassembly is time-consuming and labor-intensive, reducing work efficiency. Moreover, the disassembly and assembly process can easily damage the inner and outer rings and rolling elements of the bearing, increasing equipment maintenance costs and downtime. On the other hand, traditional bearings mostly use grease lubrication or oil bath lubrication, and the lubrication medium is prone to failure in high-temperature environments, leading to accelerated bearing wear and shortening service life. Therefore, a high-temperature oil-free lubricated bearing that is easy to disassemble and assemble is needed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-temperature resistant, oil-free lubricated bearing that is easy to assemble and disassemble.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A high-temperature resistant, oil-free lubricated bearing that is easy to disassemble and assemble includes an outer ring. Disassembly mechanisms are respectively provided on both sides of the surface of the outer ring. Each disassembly mechanism includes a retaining ring one, a threaded groove on one side of the retaining ring one, a retaining ring two threadedly connected to the inner wall of the threaded groove, a sliding groove on the side surface of the retaining ring two, limit grooves on both sides of the retaining ring one, and a pull rod slidably connected to both sides of the surface of the retaining ring one. A handle is fixedly connected to one end of the pull rod.

[0006] As a further embodiment of this utility model: a spring is sleeved on the surface of the pull rod, one end of the spring is fixedly connected to a limiting ring, and the end of the spring away from the limiting ring is fixedly connected to the inner wall of one side of the limiting groove.

[0007] As a further embodiment of this utility model: the limiting ring is fixedly connected to the inner wall of the limiting groove, the end of the pull rod away from the handle is adapted to the sliding groove, and the inner wall of the second retaining ring is provided with a fixing groove.

[0008] As a further embodiment of this utility model: the inner wall of the fixing groove is respectively fitted with washer one and washer two, the inner walls of washer one and washer two are slidably connected with cylindrical rollers at equal distances, and the surface of the cylindrical rollers is slidably connected with an inner ring.

[0009] As a further improvement of this utility model: the inner fabric of the inner ring is provided with a fixing mechanism, the fixing mechanism includes a retaining ring three, the retaining ring three is slidably connected to the surface of the cylindrical roller, and a protrusion is fixedly connected to the side of the retaining ring three.

[0010] As a further embodiment of this utility model: the retaining ring three is engaged with the retaining ring four, the surface of the retaining ring four is slidably connected to the cylindrical roller, and a retaining groove is provided on one side of the retaining ring four.

[0011] As a further improvement of this utility model: the slot is adapted to the protrusion, and the sides of the retaining ring three and retaining ring four are respectively provided with fixing holes, and the inner wall of the fixing hole is threaded with a bolt.

[0012] Compared with the prior art, this utility model provides a high-temperature resistant oil-free lubricated bearing that is easy to disassemble and assemble, and has the following beneficial effects: 1. This high-temperature resistant, oil-free lubricated bearing, which is easy to disassemble and assemble, features a disassembly mechanism and a fixing mechanism. To disassemble or assemble the outer ring, the pull rod connected to the two handles is pulled outwards, compressing the spring. Once the two pull rods are in the appropriate position, the retaining ring two can be rotated to disassemble or assemble the outer ring. After releasing the two handles, the two pull rods return to their original position under the action of the spring. To install the outer ring, the operator pulls the pull rod connected to the two handles outwards. Once the two pull rods are in the appropriate position, the retaining ring two is rotated into the threaded groove, and the two handles are released. The two pull rods are then locked into the sliding groove, completing the installation. Its disassembly and assembly structure is simple, saving time and effort during disassembly and improving work efficiency. To disassemble the inner ring, the retaining ring three and the two bolts on the protrusion are removed with a tool. To install, the protrusion of retaining ring three is aligned with the groove of retaining ring four, and the two bolts are aligned with the two fixing holes and secured with a tool. The disassembly and assembly process is unlikely to damage the bearing, reducing equipment maintenance costs and downtime.

[0013] 2. This easy-to-disassemble high-temperature oil-free lubricated bearing features two washers, an outer ring and an inner ring, both made of high-temperature alloy materials. Both washers are made of nickel-based alloy composite materials, and the surface layer of the inner ring is also made of nickel-based alloy composite material. This allows it to form a stable lubricating film at high temperatures, preventing direct metal-to-metal contact and reducing the coefficient of friction. The cylindrical rollers are made of silicon nitride ceramic material, which has the characteristics of high temperature resistance, low density, and high hardness, effectively reducing frictional loss during bearing operation. Compared with traditional bearings, it possesses the characteristics of high temperature resistance and oil-free lubrication, eliminating concerns about lubricant failure and increasing its service life.

[0014] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

[0020] A high-temperature resistant, oil-free lubricated bearing that is easy to disassemble and assemble, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it includes an outer ring 2, and disassembly mechanisms 1 are respectively provided on both sides of the surface of the outer ring 2. The disassembly mechanism 1 includes a retaining ring 101. A threaded groove 102 is provided on one side of the retaining ring 101. A retaining ring 2 104 is threadedly connected to the inner wall of the threaded groove 102. A sliding groove 105 is provided on the side surface of the retaining ring 2 104. Limiting grooves 103 are provided inside both sides of the retaining ring 101. A pull rod 106 is slidably connected to both sides of the surface of the retaining ring 101. A handle 107 is fixedly connected to one end of the pull rod 106.

[0021] In order to be able to disassemble and assemble the outer ring 2, such as Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a spring 108 is sleeved on the surface of the pull rod 106. One end of the spring 108 is fixedly connected to a limit ring 109, and the other end of the spring 108 away from the limit ring 109 is fixedly connected to the inner wall of one side of the limit groove 103.

[0022] The limiting ring 109 is fixedly connected to the inner wall of the limiting groove 103. The end of the pull rod 106 away from the handle 107 is adapted to the slide groove 105. The inner wall of the retaining ring 104 is provided with a fixing groove 6.

[0023] When the outer ring 2 of the bearing needs to be disassembled or assembled, the operator pulls the pull rod 106 connected by the two handles 107 outwards. During this process, the spring 108 is compressed. After the two pull rods 106 move outwards to the appropriate position, the retaining ring 104 is rotated to disassemble or assemble the outer ring 2. After releasing the two handles 107, the two pull rods 106 return to their original position under the action of the spring 108. When the outer ring 2 needs to be installed, the operator pulls the pull rod 106 connected by the two handles 107 outwards. After the two pull rods 106 move to the appropriate position, the retaining ring 104 is rotated into the threaded groove 102, and the two handles 107 are released. The two pull rods 106 are then locked into the sliding groove 105 to complete the installation. The disassembly and assembly structure is simple, saving time and effort during disassembly and improving work efficiency.

[0024] In order to enable the bearing to have high temperature resistance and oil-free lubrication characteristics, such as Figure 2 , Figure 4 and Figure 6 As shown, washer 7 and washer 8 are respectively engaged on the inner wall of the fixing groove 6. Cylindrical rollers 4 are slidably connected at equal distances on the inner walls of washer 7 and washer 8. Inner rings 3 are slidably connected to the surface of cylindrical rollers 4.

[0025] Both the outer ring 2 and the inner ring 3 are made of high-temperature alloy materials. The materials of washer 7 and washer 8 are both made of nickel-based alloy composite materials. The surface layer of the inner ring 3 is also made of nickel-based alloy composite material, which can form a stable lubricating film in high-temperature environments, avoiding direct contact between metals and reducing the coefficient of friction. The cylindrical roller 4 is made of silicon nitride ceramic material, which has the characteristics of high temperature resistance, low density, and high hardness, which can effectively reduce friction loss during bearing operation. Compared with traditional bearings, it has the characteristics of high temperature resistance and oil-free lubrication, eliminating concerns about lubrication medium failure and increasing its service life.

[0026] In order to allow the inner ring 3 to be disassembled and assembled, such as Figure 1 , Figure 2 and Figure 6 As shown, the inner fabric of the inner ring 3 is provided with a fixing mechanism 5. The fixing mechanism 5 includes a retaining ring 3 501, which is slidably connected to the surface of the cylindrical roller 4. A protrusion 504 is fixedly connected to the side of the retaining ring 3 501.

[0027] Snap ring 3 501 is snapped into snap ring 4 502. The surface of snap ring 4 502 is slidably connected to cylindrical roller 4. A snap groove 503 is provided on one side of snap ring 4 502.

[0028] The slot 503 is compatible with the protrusion 504. The sides of the retaining ring 3 501 and retaining ring 4 502 are respectively provided with fixing holes, and the inner wall of the fixing holes is threaded with bolts 505.

[0029] When the inner ring 3 needs to be disassembled, simply remove the two bolts 505 on the retaining ring 3 501 and the protrusion 504 with a tool. When it needs to be installed, align the protrusion 504 of the retaining ring 3 501 with the groove 503 of the retaining ring 4 502, then align the two bolts 505 with the two fixing holes, and fix it with a tool. The disassembly and assembly process is less likely to damage the bearing, reducing equipment maintenance costs and downtime.

[0030] Working principle: When the outer ring 2 of the bearing needs to be disassembled or assembled, the operator pulls the pull rod 106 connected by the two handles 107 outward. During this process, the spring 108 is compressed. When the two pull rods 106 move outward to the appropriate position, the retaining ring 104 is rotated to disassemble or assemble the outer ring 2. After releasing the two handles 107, the two pull rods 106 return to their original position under the action of the spring 108. When the outer ring 2 needs to be installed, the operator pulls the pull rod 106 connected by the two handles 107 outward. After the two pull rods 106 move to the appropriate position, the retaining ring 104 is rotated into the threaded groove 102, and then the two handles 107 are released. The two pull rods 106 are then locked with the sliding groove 105, completing the installation. When the inner ring 3 needs to be disassembled... Simply remove the two bolts 505 on the retaining ring 3 501 and the protrusion 504 with a tool. When installation is required, align the protrusion 504 of the retaining ring 3 501 with the groove 503 of the retaining ring 4 502, then align the two bolts 505 with the two fixing holes, and fix them with a tool. The outer ring 2 and inner ring 3 are both made of high-temperature alloy material. The materials of the washers 1 7 and 2 8 are both made of nickel-based alloy composite material. The surface layer of the inner ring 3 is also made of nickel-based alloy composite material, which can form a stable lubricating film in a high-temperature environment, avoid direct contact between metals, and reduce the coefficient of friction. The cylindrical roller 4 is made of silicon nitride ceramic material, which has the characteristics of high temperature resistance, low density, and high hardness, and can effectively reduce friction loss during bearing operation.
