Description

Technical Field

[0001] This utility model relates to the field of high-strength bearing technology, and more specifically, to a high-strength bearing. Background Technology

[0002] Rolling bearings are precision mechanical components that convert the sliding friction between a rotating shaft and its housing into rolling friction, thereby reducing frictional losses. Current rolling bearings mainly consist of an outer ring, an inner ring, balls, and a cage; some fully ball-bearing rolling bearings also include a cage.

[0003] A search revealed that Chinese utility model patent application number CN202421679794.4 discloses a high-strength wear-resistant bearing, including an outer ring, an inner ring on the inner side of the outer ring, and a lubrication assembly inside the outer ring. The lubrication assembly includes oil-absorbing fibers located inside the outer ring. The cross-section of the oil-absorbing fibers is annular. An oil outlet ring is located inside the oil-absorbing fibers, and multiple oil leakage holes are opened inside the oil outlet ring. Multiple extrusion blocks are located outside the oil outlet ring, between the oil-absorbing fibers and the oil outlet ring. Multiple oil injection holes are opened inside the outer ring, located at the top of the oil-absorbing fibers. Each oil injection hole is equipped with a one-way valve.

[0004] Its soundproof sealing cover is connected to the outer ring by inserting a rod into the hole. During use, the rod can easily slide out of the hole, and the soundproof sealing cover can easily fall off the high-strength bearing. The soundproof sealing cover has poor installation and fixation stability. In addition, lubricating oil is injected into the high-strength bearing through the oil injection hole. Since the oil injection hole is exposed, impurities such as mud and sand can easily enter the oil injection hole, affecting the injection of lubricating oil into the bearing. Utility Model Content

[0031] Please see Figures 1-6 A high-strength bearing includes a high-strength bearing 1 and a soundproof sealing cover 2. The high-strength bearing 1 includes an outer ring 3 and an inner ring 4. A ball bearing structure 5 is provided between the outer ring 3 and the inner ring 4. A washer 6 is provided on the rear side between the outer ring 3 and the inner ring 4. The front end of the outer ring 3 is provided with a plurality of threaded holes 7 in a circular array. The soundproof sealing cover 2 is connected to the outer ring 3 by a plurality of first screws 8. The plurality of first screws 8 are screwed into the plurality of threaded holes 7 respectively. Countersunk grooves 9 are provided on the soundproof sealing cover 2 at positions corresponding to the plurality of first screws 8. The side end of the first screw 8 contacts the side end of the soundproof sealing cover 2. A fixing ring 20 is fixedly connected to the side end of the soundproof sealing cover 2. The fixing ring 20 is sleeved on the outside of the inner ring 4 and plays a positioning role for the soundproof sealing cover 2. A second annular groove 21 is provided inside the fixing ring 20. A wear-resistant sealing ring 22 is provided inside the second annular groove 21 to ensure the sealing between the fixing ring 20 and the inner ring 4.

[0032] Specifically, by screwing multiple first screws 8 into the interior of multiple threaded holes 7, the soundproof sealing cover 2 is fixedly installed on the outer ring 3. Compared with the prior art, this improves the stability of the connection between the soundproof sealing cover 2 and the outer ring 3 and prevents the soundproof sealing cover 2 from falling off the outer ring 3.

[0033] Please see Figure 3 , Figure 4 and Figure 6 The soundproof sealing cover 2 has multiple oil injection holes 10 evenly distributed on its exterior. Each oil injection hole 10 is threaded with a sealing screw 11 to facilitate sealing and prevent dirt and sand from entering. This allows lubricating oil to be injected into the high-strength bearing 1. The soundproof sealing cover 2 has external threads 12, and a retaining ring 13 is threaded onto these threads. A first annular groove 14 is provided on the retaining ring 13 at a position corresponding to the multiple oil injection holes 10. The side end of the first annular groove 14 contacts the side end of the multiple sealing screws 11, facilitating the sealing of the multiple sealing screws. To prevent the sealing screw 11 from falling off, a sealing ring 15 is fixedly connected inside the fixing ring 13. A first sealing gasket 16 is fixedly connected to the side of the sealing ring 15 near the soundproof sealing cover 2. The first sealing gasket 16 covers the outside of the multiple countersunk grooves 9 to seal the multiple countersunk grooves 9. At the same time, the side end of the first sealing gasket 16 contacts the side end of the first screw 8 to prevent the first screw 8 from loosening. The end of the first sealing gasket 16 near the soundproof sealing cover 2 is provided with anti-slip texture 17 to increase the friction between the first sealing gasket 16 and the soundproof sealing cover 2 and prevent the sealing ring 15 and the fixing ring 13 from loosening.

[0034] Specifically, by screwing multiple sealing screws 11 into the interior of multiple oil injection holes 10, the oil injection holes 10 are sealed to prevent mud and sand from entering them. This facilitates the injection of lubricating oil into the high-strength bearing 1 through the oil injection holes 10, while preventing mud and sand from entering the bearing 1 during the lubrication process. The retaining ring 13 is screwed onto the outside of the soundproof sealing cover 2. The multiple sealing screws 11 are located inside the first annular groove 14, and the side ends of the multiple sealing screws 11 contact the side ends of the first annular groove 14 to prevent the sealing screws 11 from loosening or falling out of the oil injection holes 10. At the same time, the sealing ring 15 covers the outside of multiple countersunk grooves 9, and the side end of the first sealing gasket 16 contacts the side ends of multiple first screws 8 to prevent the first screws 8 from loosening. This improves the stability of the connection between the soundproof sealing cover 2 and the high-strength bearing 1.

[0035] Please see Figure 1 The fixing ring 13 is symmetrically fixedly connected to two fixing blocks 18, and each fixing block 18 is provided with a slot 19.

[0036] Specifically, insert the plate or rod with the handle into the two slots 19, rotate the plate or rod by the handle, and rotate the two fixing blocks 18 and the fixing ring 13 by the plate or rod, so that the fixing ring 13 can be screwed onto the outside of the soundproof sealing cover 2, and at the same time, it is easy to unscrew the fixing ring 13 from the outside of the soundproof sealing cover 2.

[0037] In summary, when using the overall equipment:

[0038] The soundproof sealing cover 2 is fixedly installed on the outer ring 3 by screwing multiple first screws 8 into the multiple threaded holes 7 respectively. After the high-strength bearing 1 is filled with lubricating oil, the sealing screw 11 is screwed into the oil filling hole 10. Then the retaining ring 13 is screwed into the outside of the soundproof sealing cover 2. When it is necessary to fill the high-strength bearing 1 with lubricating oil, the retaining ring 13 is unscrewed from the outside of the soundproof sealing cover 2 and the sealing screw 11 is unscrewed. Then the lubricating oil is filled into the high-strength bearing 1 through the oil filling hole 10.

[0039] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred.
