DETAILED DESCRIPTION

[0024] See also Figure 1-Figure 7 , a bearing ring that is easy to assemble, comprising an outer sleeve 1 and an inner sleeve 2 arranged inside the outer sleeve 1, a ball member 3 is arranged between the outer sleeve 1 and the inner sleeve 2, and sealing plates 4 are connected to the left and right sides of the outer sleeve 1:

[0025] The bearing ring is composed of an outer sleeve 1 and an inner sleeve 2, wherein the ball member 3 is located between the outer sleeve 1 and the inner sleeve 2, and plays the role of bearing and reducing friction. The left and right sides of the outer sleeve 1 are also provided with sealing plates 4 to prevent dust and other impurities from entering the interior of the bearing, and also to keep the grease from leaking.

[0026] Furthermore, the outer sleeve 1 includes a first sleeve 101 and a second sleeve 102 that are clamped together, a sliding groove 103 is opened at corresponding upper and lower positions on one side of the first sleeve 101, a first slide rod 104 is slidably connected inside the sliding groove 103, a positioning block 107 is fixedly connected to one side of the first slide rod 104, an installation groove 108 is opened at corresponding upper and lower positions on one side of the second sleeve 102, a second slide rod 109 is slidably connected inside the installation groove 108, a positioning slot 110 is opened at one side of the second slide rod 109, and the positioning slot 110 and the positioning block 107 are clamped together.

[0027] When the bearing ring needs to be assembled, the operator can sleeve the mounting frame 301 on the outside of the inner sleeve 2, and then sleeve the first sleeve 101 and the second sleeve 102 on the outside of the mounting frame 301. In order to facilitate the clamping connection between the first sleeve 101 and the second sleeve 102, the operator can pull the first slide bar 104 outward along the inner wall of the slide groove 103 through the fixing rod 105. The first slide bar 104 drives the positioning block 107 to slide along the inner wall of the mounting groove 108 until the positioning block 107 is inserted into the positioning slot 110. The first The positions of the sleeve 101 and the second sleeve 102 are precisely positioned during assembly to ensure the concentricity and stability of the bearing after assembly. The remaining first slide rod 104 is inserted into the corresponding installation groove 108 through the same operation to facilitate the rapid assembly of the first sleeve 101 and the second sleeve 102. Finally, the sealing plate 4 can be fixed to the gap on the left and right sides of the first sleeve 101 and the second sleeve 102 to complete the rapid assembly of the bearing ring. The above design simplifies the assembly process of the bearing and improves the assembly efficiency. At the same time, the precise positioning structure ensures the working performance and service life of the bearing.

[0028] Furthermore, a fixing rod 105 is fixedly connected to the top of the first slide rod 104 , one end of the fixing rod 105 extends to the outside of the first sleeve 101 and is slidably connected to the inner wall of the slide groove 103 , and a first spring 106 is fixedly connected between the slide groove 103 and the first slide rod 104 .

[0029] During the assembly process, the movement of the first slide bar 104 can be controlled by operating the fixing rod 105. The fixing rod 105 is slidably connected to the inner wall of the slide groove 103, ensuring that when the first slide bar 104 is moved, its movement trajectory is smooth and will not deviate from the slide groove 103. The function of the first spring 106 is to provide a restoring force, so that the first slide bar 104 can automatically return to its initial position without applying external force. When assembling, the positioning block 107 is pushed into the positioning slot 110 on the second sleeve 102 by compressing the first spring 106 to complete the locking between the sleeves; during disassembly, the elastic force of the first spring 106 helps to quickly separate the two sleeves, greatly simplifying the disassembly and assembly process of the bearing, and also provides the necessary preload force for the bearing, which is beneficial to improving the working stability and reliability of the bearing.

[0030] Furthermore, a second spring 111 is fixedly connected between the mounting groove 108 and the second sliding rod 109 .

[0031] When the second slide bar 109 is pushed during the bearing installation process, the second spring 111 will be compressed to store energy. Once the external force is removed, the restoring force of the second spring 111 will help the second slide bar 109 and the positioning slot 110 thereon return to the correct position, and firmly engage with the positioning plug 107 on the first sleeve 101, ensuring that the two sleeves are tightly combined and the axial position is accurate.

[0032] Furthermore, the ball member 3 includes a mounting frame 301 arranged inside the first sleeve 101 and the second sleeve 102, a plurality of balls 302 are rotatably connected to the inner wall of the mounting frame 301, a plurality of oil injection pipes 303 are fixedly connected to the surface of the mounting frame 301, and a piston 304 is movably connected to one end of the oil injection pipe 303.

[0033] Since the inner wall of the mounting frame 301 is designed to allow the balls 302 to rotate, that is, multiple balls 302 are evenly distributed in the mounting frame 301. They reduce friction and carry load by rolling when the bearing is working. The oil filling pipe 303 directly leads to the interior of the bearing to facilitate lubrication of the balls 302 and the interior of the bearing. A piston 304 is provided at one end of the oil filling pipe 303. By operating the piston 304, the amount of grease injected can be accurately controlled to ensure that the bearing is fully and effectively lubricated, thereby improving the service life and operating efficiency of the bearing.

[0034] Furthermore, the first sleeve 101 and the second sleeve 102 are respectively provided with a first opening 112 and a second opening 113 , and one end of the piston 304 passes through the first sleeve 101 and the second sleeve 102 and extends to the outside of the first sleeve 101 and the second sleeve 102 .

[0035] When it is necessary to add lubricating oil to the inside of the bearing or replace the lubricating oil, it is only necessary to directly operate the piston 304 from the outside. The pushing and pulling action of the piston 304 will inject the lubricating oil into the inside of the mounting frame 301 through the oil filling pipe 303 to lubricate the ball 302 and other working surfaces of the bearing. This design simplifies the lubrication and maintenance procedures of the bearing, and can achieve simple and fast lubrication management without disassembling the bearing, which not only saves maintenance time, but also reduces the potential loss caused by frequent disassembly and assembly, and significantly improves the operation and maintenance efficiency and service life of the bearing.

[0036] Furthermore, the first sleeve 101, the second sleeve 102 and the inner sleeve 2 are all made of bearing steel material.

[0037] The first sleeve 101, the second sleeve 102 and the inner sleeve 2 are made of bearing steel material, which can ensure that the entire bearing structure has excellent mechanical properties and a long service life. At the same time, combined with the easy assembly and lubrication design mentioned above, this bearing shows high practicality and economy in use and maintenance.

[0038] Furthermore, the mounting frame 301 and the ball bearing 302 are both made of stainless steel.

[0039] The stainless steel material has excellent corrosion resistance and is particularly suitable for applications in humid environments with chemical media or salt spray. It can effectively prevent the failure of the ball 302 and the damage of the mounting frame 301 due to corrosion, thereby extending the service life of the bearing.

[0040] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
