The installation process involves a large number of parts and complex steps, and the operator needs to spend a lot of time and energy to complete the installation. This complicated installation process seriously affects work efficiency, making the equipment assembly or maintenance work that could be completed quickly become complicated. At the same time, the bearing sealing mechanism also brings great trouble during later maintenance. Because its installation is tight and complicated, it is easy to damage the sealing mechanism itself or other related parts during disassembly, which not only increases the difficulty of maintenance, but also may increase the maintenance cost.

[0004] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0005] The utility model is a bearing sealing mechanism, comprising an inner ring, on which a sealing mechanism and a configuration mechanism are provided.

[0006] The sealing mechanism includes a retaining frame module arranged on the outer wall of the inner ring, the inner wall of the retaining frame module is rotatably sleeved with a ball module, the outer wall of the ball module is provided with an outer ring, the top and bottom of the inner ring and the outer ring are provided with dustproof grooves, the inner walls of the two dustproof grooves are provided with two sealing grooves, the inner walls of the two dustproof grooves are slidably connected with dustproof covers, the bottoms of the two dustproof covers are fixedly connected with two sealing rings 1, several of the sealing rings 1 are adapted to the several sealing grooves, the top and bottom of the outer ring are provided with several fixing grooves, the outer walls of the two dustproof covers are fixedly connected with several U-shaped blocks, several of the U-shaped blocks are adapted to the several fixing grooves, several of the U-shaped blocks are threadedly connected with bolts, and the ends of several of the bolts extend into the outer ring.

[0007] Furthermore, the configuration mechanism includes a circular groove opened on the top of the corresponding dust cover, the inner wall of the circular groove is fixedly connected with a liquid inlet pipe, and the liquid inlet pipe is adapted to the inner ring and the outer ring.

[0008] Furthermore, the inner wall of the liquid inlet pipe is fixedly connected with a second sealing ring, the top end of the liquid inlet pipe is slidably connected with a pull rod, the bottom end of the pull rod is fixedly connected with a piston, and the piston is adapted to the second sealing ring.

[0009] Furthermore, a spring is wound around the outer wall of the pull rod, one end of the spring is fixedly connected to the liquid inlet pipe, and the other end of the spring is fixedly connected to the piston.

[0010] Furthermore, a connecting pipe is fixedly connected to the outer wall of the liquid inlet pipe, and the connecting pipe is communicated with the liquid inlet pipe.

[0011] The utility model has the following beneficial effects:

[0012] (1) The present invention sets a sealing mechanism. When in use, the ball module is first installed on the retaining frame module in a specific order and position. After the installation is completed, the retaining frame module and the ball module on it are placed between the inner ring and the outer ring. During the placement process, attention should be paid to the accuracy of its position so that the ball module can fit well with the raceways of the inner ring and the outer ring, laying a solid foundation for subsequent normal operation. After placement, the dust cover and the bottom sealing ring are inserted into the sealing groove and dust groove on the inner ring and the outer ring in turn. When inserting, it is necessary to ensure that the sealing ring fits tightly in the sealing groove to give full play to its sealing performance and prevent the lubricant inside the bearing from leaking. At the same time, it is also necessary to ensure that the dust cover can be accurately embedded in the dust groove to prevent dust, impurities and other foreign matter from entering the bearing. Then, the U-shaped block on the dust cover is fixed with bolts so that the dust cover can firmly fix the inner ring and the outer ring together. Through such a setting, the efficiency of the entire installation process can be improved and unnecessary time waste and installation errors can be reduced.

[0013] (2) The present invention sets up a configuration mechanism. If lubricant needs to be added to the ball module, the pull rod can be pulled outward first. In the process of pulling the pull rod, the pull rod will drive the piston to move upward in a specific direction, and at the same time compress the spring on the outer wall of the pull rod. When the spring is compressed, it can convert the external force into elastic potential energy and store it. The stored energy provides sufficient power for the subsequent reset operation. In addition, when the piston moves upward, it will separate from the sealing ring 2 on the inner wall of the liquid inlet pipe, thereby forming a channel for the flow of lubricant between the piston and the sealing ring 2. Then, lubricant is poured into the liquid inlet pipe through the connecting pipe. Under the action of gravity or external pressure, the lubricant can smoothly pass through the liquid inlet pipe into the area where the ball module is located, thereby assisting the ball module to roll more smoothly, reducing the friction and wear between the ball and the raceway, and thus improving the service life. Of course, any product implementing the present invention does not necessarily need to achieve all the advantages mentioned above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The sealing mechanism 2 includes a retaining frame module 21 arranged on the outer wall of the inner ring 1, and a ball module 22 is rotatably sleeved on the inner wall of the retaining frame module 21, and an outer ring 23 is provided on the outer wall of the ball module 22. Dustproof grooves 24 are provided on the top and bottom of the inner ring 1 and the outer ring 23, and two sealing grooves 25 are provided on the inner walls of the two dustproof grooves 24. Dustproof covers 26 are slidably connected to the inner walls of the two dustproof grooves 24, and two sealing rings 27 are fixedly connected to the bottoms of the two dustproof covers 26. Several sealing rings 27 are adapted to the several sealing grooves 25. Several fixing grooves 28 are provided on the top and bottom of the outer ring 23, and several U-shaped blocks 29 are fixedly connected to the outer walls of the two dustproof covers 26. Several U-shaped blocks 29 are adapted to the several fixing grooves 28. Bolts 291 are threadedly connected to the several U-shaped blocks 29, and the ends of the several bolts 291 extend into the outer ring 23.

[0024] By setting up a sealing mechanism, when in use, first install the ball module 22 on the retaining frame module 21 in a specific order and position. After installation is completed, place the retaining frame module 21 and the ball module 22 thereon between the inner ring 1 and the outer ring 23. During the placement process, pay attention to the accuracy of its position, so that the ball module 22 can fit well with the raceways of the inner ring 1 and the outer ring 23, laying a solid foundation for subsequent normal operation. After proper placement, insert the dust cover 26 and the sealing ring 27 at the bottom into the sealing groove 25 and the dust groove 24 on the inner ring 1 and the outer ring 23 in turn. When inserting, ensure that the sealing ring 27 fits tightly in the sealing groove 25 to give full play to its sealing performance and prevent the lubricant inside the bearing from leaking. At the same time, ensure that the dust cover 26 can be accurately embedded in the dust groove 24 to prevent dust, impurities and other foreign matter from entering the bearing. Then, use bolts 291 to tighten the U on the dust cover 26. The block 29 is fixed so that the dust cover 26 can firmly fix the inner ring 1 and the outer ring 23 together. Through this arrangement, the efficiency of the entire installation process can be improved, and unnecessary time waste and installation errors can be reduced.

[0025] The configuration mechanism 3 includes a circular groove 31 opened on the top of the corresponding dust cover 26, and the inner wall of the circular groove 31 is fixedly connected with a liquid inlet pipe 32, which is adapted to the inner ring 1 and the outer ring 23, and the inner wall of the liquid inlet pipe 32 is fixedly connected with a sealing ring 2 33, and the top of the liquid inlet pipe 32 is slidably connected with a pull rod 34, and the bottom end of the pull rod 34 is fixedly connected with a piston 35, which is adapted to the sealing ring 2 33, and the outer wall of the pull rod 34 is wrapped with a spring 36, one end of the spring 36 is fixedly connected to the liquid inlet pipe 32, and the other end of the spring 36 is fixedly connected to the piston 35, and the outer wall of the liquid inlet pipe 32 is fixedly connected with a connecting pipe 37, and the connecting pipe 37 is communicated with the liquid inlet pipe 32.

[0026] By setting up a configuration mechanism, if lubricant needs to be added to the ball module 22, the pull rod 34 can be pulled outward first. In the process of pulling the pull rod 34, the pull rod 34 will drive the piston 35 to move upward in a specific direction, and at the same time compress the spring 36 on the outer wall of the pull rod 34. When the spring 36 is compressed, it can convert the external force into elastic potential energy and store it. The stored energy provides sufficient power for the subsequent reset operation. Moreover, when the piston 35 moves upward, it will separate from the sealing ring 2 33 on the inner wall of the liquid inlet pipe 32, thereby forming a channel for the flow of lubricant between the piston 35 and the sealing ring 2 33. Then, the lubricant is poured into the liquid inlet pipe 32 through the connecting pipe 37. Under the action of gravity or external pressure, the lubricant can smoothly pass through the liquid inlet pipe 32 into the area where the ball module 22 is located, thereby assisting the ball module 22 to roll more smoothly, reducing the friction and wear between the ball and the raceway, and thus improving the service life.

[0027] A specific application of this embodiment is as follows: when in use, first install the ball module 22 on the retaining frame module 21 in a specific order and position. After the installation is completed, the retaining frame module 21 and the ball module 22 thereon are placed between the inner ring 1 and the outer ring 23. During the placement process, attention should be paid to the accuracy of its position, so that the ball module 22 can fit well with the raceways of the inner ring 1 and the outer ring 23, laying a solid foundation for subsequent normal operation. After proper placement, the dust cover 26 and the sealing ring 27 at the bottom are inserted into the sealing groove 25 and the dust groove 24 on the inner ring 1 and the outer ring 23 in turn. When inserting, it is necessary to ensure that the sealing ring 27 fits tightly in the sealing groove 25 to give full play to its sealing performance to prevent the lubricant inside the bearing from leaking. At the same time, it is also necessary to ensure that the dust cover 26 can be accurately embedded in the dust groove 24 to prevent dust, impurities and other foreign matter from entering the bearing. Then, use bolts 291 to tighten the U on the dust cover 26. The block 29 is fixed so that the dust cover 26 can firmly fix the inner ring 1 and the outer ring 23 together. This arrangement can improve the efficiency of the entire installation process and reduce unnecessary time waste and installation errors. If lubricant needs to be added to the ball module 22, the pull rod 34 can be pulled outward first. In the process of pulling the pull rod 34, the pull rod 34 will drive the piston 35 to move upward in a specific direction, and at the same time compress the spring 36 on the outer wall of the pull rod 34. When the spring 36 is compressed, it can convert the external force into elastic potential energy and store it. The energy provides sufficient power for the subsequent resetting operation, and when the piston 35 moves upward, it will separate from the sealing ring 2 33 on the inner wall of the liquid inlet pipe 32, thereby forming a channel for the flow of lubricant between the piston 35 and the sealing ring 2 33. Then, the lubricant is poured into the liquid inlet pipe 32 through the connecting pipe 37. Under the action of gravity or external pressure, the lubricant can smoothly pass through the liquid inlet pipe 32 into the area where the ball module 22 is located, thereby assisting the ball module 22 to roll more smoothly, reducing the friction and wear between the ball and the raceway, and thus improving the service life.
