Description

Technical Field

[0001] The present application relates to the technical field of rolling bearings, and in particular to a rolling bearing with a bearing outer ring. Background Art

[0002] Rolling bearings are common mechanical components used to support rotating shafts or bearing housings, transfer loads, and reduce friction. They primarily consist of an inner ring, an outer ring, rolling elements (such as balls, rollers, and cylindrical rollers), and a cage (or retainer).

[0003] The existing Chinese patent with announcement number CN220320109U discloses a bearing outer ring and a rolling bearing having the bearing outer ring, including an outer ring body, a roller, a front cage and an inner ring body. A first limiting groove is opened at the center position of the inner ring of the outer ring body, and the cross-section of the first limiting groove is arc-shaped. The outer surface of the outer ring body and the first limiting groove is plated with a chrome plating layer, and the outer surface of the chrome plating layer is plated with a diamond coating. The utility model is provided with a chrome plating layer on the outer surface of the outer ring body, and the chrome plating layer enhances the wear resistance, fatigue resistance, corrosion resistance and self-lubrication properties of the surface layer. At the same time, the chrome plating layer can quickly form an extremely thin passivation film on the surface of the outer ring body, which can resist corrosion from the atmosphere, alkali and certain acids. The hardness of the coating is relatively high, which can improve the wear resistance of the outer ring body surface. At the same time, a diamond coating is provided, and the hardness of the diamond coating is high, so that the outer ring body has a higher hardness and better wear resistance, and the outer ring body has good corrosion resistance.

[0004] However, the above-mentioned rolling bearing has the following disadvantages: the device improves the hardness and wear resistance of the bearing by providing an outer ring body, a diamond coating, a chrome plating layer and a first limit groove, but the device cannot quickly install and disassemble the front and rear cages of the roller, which increases the disassembly and maintenance time of the staff. At the same time, the front and rear cages cannot be accurately positioned during installation, and the rollers cannot be lubricated when rotating, so that the rollers may wear due to friction overheating, thereby reducing their service life.

[0005] Therefore, we propose a rolling bearing with a bearing outer ring to solve this problem.

[0006] The above information disclosed in this background technology is only used to increase the understanding of the background technology of this application. Therefore, it may contain information that does not constitute the prior art known to ordinary technicians in this field. Utility Model Content

[0008] The present application provides a rolling bearing with a bearing outer ring adopts the following technical solution:

[0009] A rolling bearing with a bearing outer ring comprises an outer ring body, a bearing inner ring is arranged inside the outer ring body, a groove is arranged between the bearing inner ring and the outer ring body, a plurality of rollers are arranged between the two grooves, a front retainer is arranged on the top of the plurality of rollers, a rear retainer is arranged on the bottom of the plurality of rollers, a plurality of rotating shafts are rotatably installed on the top of the front retainer, a limit plate is fixedly installed on the bottom end of the plurality of rotating shafts, a plurality of limit slots are opened through the rear retainer, the limit blocks are adapted to the limit slots, and the tops of the plurality of limit plates are in contact with the bottom wall of the rear retainer.

[0010] Preferably, a handle is fixedly mounted on the top of each of the plurality of rotating shafts.

[0011] Preferably, dustproof plates are provided on the top and bottom of the inner ring and outer ring bodies of the bearing.

[0012] Preferably, an oil storage cylinder is fixedly mounted on the bottom of the dustproof plate at the top, and a plurality of balls are rotatably mounted on the bottoms of the oil storage cylinders, and the plurality of balls are in contact with the top of the front retaining frame.

[0021] The following is combined with Figure 1-5 This application is described in further detail.

[0022] The embodiment of the present application discloses a rolling bearing with a bearing outer ring. Figure 1-5 A rolling bearing with a bearing outer ring includes an outer ring body 1, a bearing inner ring 3 is arranged inside the outer ring body 1, a groove is arranged between the bearing inner ring 3 and the outer ring body 1, a plurality of rollers 13 are arranged between the two grooves, a front retainer 5 is arranged on the top of the plurality of rollers 13, a rear retainer 12 is arranged on the bottom of the plurality of rollers 13, a plurality of rotating shafts 10 are rotatably installed on the top of the front retainer 5, a limit plate 9 is fixedly installed on the bottom end of the plurality of rotating shafts 10, a plurality of limit grooves 14 are opened through the rear retainer 12, the limit blocks are adapted to the limit grooves 14, and the tops of the plurality of limit plates 9 are aligned with the bottom wall of the rear retainer 12 Contact; by setting the limit plate 9 and the limit groove 14, the front retainer 5 and the rear retainer 12 can be quickly installed and disassembled, which simplifies maintenance work and shortens downtime. At the same time, it can ensure that the front retainer 5 and the rear retainer 12 can be accurately positioned during installation, thereby improving the accuracy and quality of the overall assembly. By setting the oil storage cylinder 7 and the ball 8, the ball 8 is pressed against the front retainer 5, and an appropriate amount of lubricating oil or grease is distributed to the contact surface of the ball 8 bearing or the roller 13 bearing for lubrication, reducing friction and wear, preventing the roller 13 bearing from premature wear and failure due to frictional overheating, and ensuring the reliability and durability of the equipment.

[0023] Reference Figure 4 A handle 11 is fixedly installed on the top of each of the multiple rotating shafts 10, which can drive the rotating shaft 10 to rotate, thereby driving the limiting plate 9 to rotate.

[0024] Reference Figure 1 and Figure 3 Dustproof plates 2 are provided on the top and bottom of the bearing inner ring 3 and the outer ring body 1 to prevent dust from entering the roller 13 and affecting the service life of the roller 13.

[0025] Reference Figure 3An oil storage cylinder 7 is fixedly installed at the bottom of the dustproof plate 2 at the top, and balls 8 are rotatably installed at the bottom of multiple oil storage cylinders 7. Multiple balls 8 are in contact with the top of the front retainer 5 and can lubricate the internal rollers 13.

[0026] Reference Figure 2-3 The top and bottom of the two dustproof plates 2 are fixed with fixing rings 6, and the top and bottom of the bearing inner ring 3 are penetrated by threaded grooves 4. The outer sides of the two fixing rings 6 are threaded, and the two fixing rings 6 are threadedly connected to the threaded grooves 4, so that the dustproof plates 2 can be quickly disassembled.

[0027] The implementation principle of a rolling bearing with a bearing outer ring in an embodiment of the present application is as follows: when the rolling bearing needs to be disassembled, the two dust plates 2 can be rotated, and the outer sides of the fixing rings 6 at the top and bottom of the two dust plates 2 can be rotated along the threaded groove 4 until the dust plates 2 rotate out of the threaded groove 4, thereby exposing the inside of the roller 13. When the roller 13 needs to be disassembled, multiple handles 11 can be manually twisted, and the multiple handles 11 drive the rotating shaft 10 to rotate, and the rotating shaft 10 drives the limit plate 9 to rotate to a position coaxial with the limit groove 14. Then the front retaining frame 5 can be removed to complete the disassembly of the roller 13. At the same time, when the roller 13 rotates, the ball 8 will drive the lubricating oil in the oil storage cylinder 7 to drip outward, and after dripping onto the front retaining frame, it will spread outward, thereby lubricating the roller 13.
