Description

Technical Field

[0001] This utility model relates to the field of ball bearing technology, and in particular to a high-strength ball bearing race. Background Technology

[0002] A bearing is a device that supports the relative motion between a mechanical shaft and rotor and transmits loads. It typically consists of an outer ring, inner ring, rolling elements, a cage, and a seal. Its main function is to reduce friction during machine movement, support and position shafts and parts, making the machinery run more smoothly and efficiently. Bearings are widely used in various mechanical equipment such as automobiles, aircraft, and generators, and are an indispensable and important component in the machinery industry.

[0003] There are various types of bearings in the existing technology, including ball bearings, which are commonly used in mechanical equipment. They transmit force through rolling balls between an inner and outer ring. Thanks to the point contact characteristics between the balls and the raceways, they can significantly reduce energy loss during the operation of mechanical equipment. However, as the rotational speed of the ball bearing increases with the mechanical equipment, its operating speed also increases accordingly. As the speed increases, the consumption rate of the internal lubricating grease also increases, which in turn increases the frictional resistance between the balls and the outer and inner rings. With continuous use, hard wear will occur, thereby reducing the strength between the outer and inner rings. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1 like Figure 1-5As shown, this utility model provides a technical solution: a high-strength ball bearing ring, including an outer ring 11, a hollow ring 13 is provided on the inner circumference of the outer ring 11, the inner circumference of the outer ring 11 is rotatably connected to the outer circumference of the hollow ring 13, an inner ring 12 is provided on the inner circumference of the hollow ring 13, the inner circumference of the hollow ring 13 is in contact with the outer circumference of the inner ring 12, an oil cavity 17 is opened inside the hollow ring 13, a fixing plate 14 is provided on one side of the hollow ring 13, the one side of the hollow ring 13 is fixedly connected to the outer side of the fixing plate 14, a cotton core water guide 15 is provided on the inner wall of the fixing plate 14, the inner wall of the fixing plate 14 is fixedly connected to the outer side of the cotton core water guide 15, a positioning plate 16 is provided on one side of the inner side of the hollow ring 13, one end of the positioning plate 16 is fixedly connected to the inner side of the hollow ring 13, the outer side of the positioning plate 16 is engaged with the inner wall of the inner ring 12, and the positioning plate 16... The inner wall is provided with a fixing member 113. The inner wall of the positioning plate 16 is threadedly connected to the outer side of the fixing member 113. One end of the fixing member 113 is fixedly connected to one side of the inner wall of the inner ring 12. The hollow ring 13 is provided with a spring 18. The inside of the hollow ring 13 is fixedly connected to one end of the spring 18. The other end of the spring 18 is fixedly connected to one end of the fixing post 19. The outer side of one end of the fixing post 19 fits into one side of the hole of the hollow ring 13. One side of the hollow ring 13 contacts one side of the sealing ring 111. The inner side of the sealing ring 111 is fixedly connected to the outer side of the inner ring 12. The outer side of the sealing ring 111 is rotatably connected to the inner side of the outer ring 11. A ball body 110 is provided between the inner ring 12 and the outer ring 11. The inner ring 12 and the outer ring 11 are rotatably connected to the ball body 110. One side of the ball body 110 is rotatably contacted with one side of the cotton core water-guiding core 15.

[0022] In this embodiment, when the high-strength ball bearing body 110 ring is in use, a hollow ring 13 is installed at the edge between the inner ring 12 and the outer ring 11. An oil cavity 17 is formed in the hollow ring 13, and a fixed plate 14 is installed and connected to one side of the hollow ring 13. This allows the oil in the oil cavity 17 to enter the fixed plate 14. A cotton core water-guiding core 15 is installed inside the fixed plate 14. The cotton core water-guiding core 15 can absorb and evenly conduct the oil through capillary action. The cotton core water-guiding core 15 contacts one side of the ball bearing body 110 between the outer ring 11 and the inner ring 12. Furthermore, during the use of the bearing, the ball body 110 will continuously maintain contact with the cotton core water guide 15 and roll relative to each other. The oil adsorbed by the cotton core water guide 15 through capillary action will be evenly coated on the surface of the ball body 110 under the friction of the rolling of the ball body 110. The oil adhering to the surface of the ball body 110 will be carried to the raceway between the ball body 110 and the outer ring 11 and the inner ring 12 as the ball body 110 rotates, reducing the wear between the ball body 110 and the raceway, so that the strength of the bearing itself will not be reduced due to wear. By installing a positioning plate 16 inside the hollow ring 13, when the hollow ring 13 is fitted onto the inner ring 12, the positioning plate 16 on the hollow ring 13 needs to be matched with the recess of the inner ring 12 to form a preliminary positioning, ensuring that the hollow ring 13 will not rotate during the subsequent fixing process. Then, the fixing member 113 is used to fix the hollow ring 13 onto the inner ring 12, so that the two form an integrated structure, ensuring the assembly stability of the bearing during operation. A fixing post 19 is installed inside the empty ring 13, i.e., the oil chamber 17, at the oil inlet. The fixing post 19 is fitted with the oil inlet. A spring 18 is installed at one end of the fixing post 19, and the other end of the spring 18 is fixed inside the empty ring 13, i.e., the oil chamber 17. When adding oil, the fixing post 19 is pushed back into the empty ring 13 by using a tool, thus opening the oil inlet channel. Oil is then added to the inside by the oil injection tool. After the oil is added, the tool is used to keep the fixing post 19 stable. Under the elastic restoring force of the spring 18, the fixing post 19 pops outward and re-fits tightly with the oil inlet, achieving automatic sealing of the oil inlet channel.

[0023] Example 2 like Figure 3-5 As shown, a fixing ring 114 is provided on the outer side of the fixing post 19. The outer side of the fixing post 19 is fixedly connected to the inner side of the fixing ring 114. A sealing ring 115 is provided at one end of the fixing ring 114. One end of the fixing ring 114 is fixedly connected to one end of the sealing ring 115. One end of the sealing ring 115 is in contact with the inside of the empty ring 13.

[0024] In this embodiment, a fixing ring 114 is installed on the outside of the fixing post 19, and a sealing ring 115 is fixed to one end of the fixing ring 114. The sealing ring 115 and the fixing ring 114 are located inside the empty ring 13, that is, inside the oil cavity 17. When the spring 18 is released, the fixing post 19 engages with the orifice. Under the elastic force, the fixing post 19 moves towards the oil inlet and precisely engages with the orifice. At the same time, the fixing ring 114 drives the sealing ring 115 to tightly adhere to the sealing surface inside the oil inlet, forming a double sealing structure, which greatly improves the sealing effect and effectively prevents the oil in the oil cavity 17 from leaking from the gap in the oil inlet. The fixing ring 114 can provide an installation carrier for the sealing ring 115, fixing it to the outside of the fixing post 19 to prevent the sealing ring from shifting. At the same time, when the spring 18 returns to its original position, it drives the sealing ring to tightly adhere to the sealing surface, increasing the sealing pressure and enhancing the sealing effect.

[0025] Working principle: like Figure 1-5As shown, a hollow ring 13 is installed at the edge between the inner ring 12 and the outer ring 11. An oil cavity 17 is formed in the hollow ring 13, allowing oil in the oil cavity 17 to enter the cotton core water guide 15 and contact one side of the ball body 110. During bearing use, the ball body 110 continuously maintains contact with the cotton core water guide 15 and undergoes relative rolling. The oil adsorbed by the cotton core water guide 15 through capillary action is evenly coated onto the surface of the ball body 110 under the frictional force of the rolling ball body 110. The oil adsorbed by the cotton core water guide 15 is then evenly coated onto the surface of the ball body 110. The oil is carried by the rotation of the ball body 110 to the raceway between the ball body 110 and the outer ring 11 and the inner ring 12, reducing the wear between the ball body 110 and the raceway. Secondly, a fixing post 19 is installed at the oil inlet. When adding oil, the fixing post 19 is pushed back into the empty ring 13 by using a tool, thus opening the oil inlet channel. Oil is added into the inlet by the oiling tool. After the oiling is completed, the fixing post 19 is kept stable by the tool. The energy of the spring 18 is released to push the fixing post 19 back, thus closing the oiling channel.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
