Description

Technical Field

[0001] This application relates to the field of bearings, and in particular to high-speed deep groove ball bearings. Background Technology

[0002] High-speed deep groove ball bearings are a type of deep groove ball bearing, consisting of an outer ring, an inner ring, a set of steel balls, and a cage. They have a simple structure and are easier to manufacture with high precision compared to other types, making them suitable for mass production. They are characterized by low frictional resistance and high speed, and are widely used in high-speed rotating mechanical parts.

[0003] During the operation of high-speed deep groove ball bearings, the steel balls continuously rub against the cage. While high-speed deep groove ball bearings require lubrication, the lubricating oil at the connection between the steel balls and the cage is significantly depleted during the rotation of the steel balls and is difficult to replenish. This can lead to insufficient lubrication between the steel balls and the cage, resulting in severe wear and reduced service life of the bearing. Utility Model Content

[0004] The purpose of this invention is to provide a high-speed deep groove ball bearing to solve the problems mentioned in the background art.

[0005] This utility model provides a high-speed deep groove ball bearing, including an outer ring. A retaining upper bracket is provided on one side of the outer ring, and multiple ball holders are fixedly connected to the bottom surface of the retaining upper bracket. Ball grooves are formed on the side walls of the ball holders, and ball bearings are rotatably connected to the inner walls of the ball grooves. A retaining lower bracket is fixedly connected to the bottom surface of the ball holders. First, the balls are placed into the ball grooves of the ball holders. Then, the retaining upper and lower brackets are placed inside the outer ring. An inner ring is provided on one side of the retaining upper and lower brackets. The inner ring is then placed inside the retaining upper bracket, thus completing the bearing installation. An outer annular groove is formed on the inner wall of the outer ring, and the inner wall of the outer annular groove abuts against the side wall of the ball bearing. An inner annular groove is formed on the side wall of the inner ring, and the inner wall of the inner annular groove abuts against the side wall of the ball bearing. After the bearing installation is completed, the outer and inner annular grooves provide a limiting and fixing function for the steel balls. The upper frame has an upper oil reservoir, and the lower frame has a lower oil reservoir. Both the upper and lower oil reservoirs have oil outlet holes on their bottom surfaces and oil inlets at their tops. The oil outlet holes are symmetrically arranged with respect to the steel balls, allowing lubricating oil to be added to the upper oil reservoir through the oil inlets. During bearing operation, the lubricating oil in the upper oil reservoir is continuously squeezed out through the symmetrically arranged oil outlet holes, providing lubrication for the rotation of the steel balls, preventing lubrication loss, reducing wear, and extending the bearing's service life.

[0006] Preferably, the bottom surface of the upper shelf is fixedly connected to multiple connecting blocks, and the bottom surface of the connecting blocks is fixedly connected to the surface of the lower shelf.

[0007] By adopting the above technical solution and setting multiple connecting blocks, during the operation of the bearing, the connecting blocks can provide a certain support and fixation for the upper and lower retaining frames, improve the rigidity of the upper and lower retaining frames, reduce the probability of deformation of the upper and lower retaining frames, thereby extending the service life of the upper and lower retaining frames and facilitating the use of the bearing.

[0008] Preferably, the connecting block has a connecting oil groove inside, and the connecting oil groove is connected to the upper oil storage tank and the lower oil storage tank.

[0009] By adopting the above technical solution and setting up the connecting oil tank, the lubricating oil poured into the upper oil storage tank and the lower oil storage tank can circulate, which improves efficiency and can store a certain amount of lubricating oil, making it convenient to lubricate the steel ball.

[0010] Preferably, the outer ring has an outer oil groove inside, and the side wall of the outer oil groove has an outer oil groove. The outer ring has an outer oil filling hole on its surface, and the outer oil filling hole is connected to the outer oil groove.

[0011] By adopting the above technical solution, the outer oil groove, the outer oil outlet groove, and the outer oil filling hole are designed so that lubricant can be added to the outer oil groove through the outer oil filling hole. When the steel ball rolls along the outer annular groove, the lubricant in the outer oil groove will be discharged from the outer oil outlet groove, thereby providing lubrication for the steel ball rolling along the outer annular groove, reducing the friction between the steel ball and the outer ring, reducing wear, and thus extending the service life of the outer ring.

[0012] Preferably, the inner ring has an inner oil groove inside, and the side wall of the inner oil groove has an inner oil outlet groove. The surface of the inner ring has an inner oil filling hole, and the inner oil filling hole is connected to the inner oil groove.

[0013] By adopting the above technical solution, the inner oil groove, the inner oil outlet groove, and the inner oil filling hole are designed so that lubricant can be added to the inner oil groove through the inner oil filling hole. When the steel ball rolls along the inner annular groove, the lubricant in the inner oil groove will be discharged from the inner oil outlet groove, thereby providing lubrication for the steel ball rolling along the inner annular groove, reducing the friction between the steel ball and the inner ring, reducing wear, and thus extending the service life of the inner ring.

[0014] Preferably, the oil inlet, external oil filling hole, and internal oil filling hole are all tapered, with a smaller top and a larger bottom.

[0015] By adopting the above technical solution, the conical design of the oil inlet, external oil filling hole and internal oil filling hole makes it difficult for the lubricating oil in the external oil groove, internal oil groove and upper oil storage tank to flow out from the oil inlet, external oil filling hole and internal oil filling hole, thus avoiding waste.

[0016] Preferably, both the oil outlet and the oil groove are tapered, with the inner part being larger than the outer part.

[0017] By adopting the above technical solution, the conical design of the oil outlet and the outer oil groove can reduce the amount of lubricating oil discharged from the oil outlet and the outer oil groove, avoid waste, and thus improve the utilization rate of lubricating oil.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] 1. First, place the balls into the ball groove of the ball cage. Then, place the upper and lower retaining frames inside the outer ring. Next, place the inner ring inside the upper retaining frame to complete the bearing installation. After the bearing is installed, the outer and inner annular grooves provide a limiting and fixing function for the balls. Lubricating oil can be added to the upper oil reservoir through the oil inlet. During the operation of the bearing, the lubricating oil in the upper oil reservoir will be continuously squeezed out through the oil outlet holes symmetrically arranged with the balls, providing lubrication for the rotation of the balls, avoiding lubrication loss, reducing wear, and thus extending the service life of the bearing.

[0020] 2. The multiple connecting blocks provide support and fixation for the upper and lower retaining frames during bearing operation, improving their rigidity, reducing the likelihood of deformation, and thus extending their service life and facilitating bearing use. Attached Figure Description

[0026] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0027] This application discloses a high-speed deep groove ball bearing.

[0028] Reference Figure 1 , Figure 2 and Figure 3 A high-speed deep groove ball bearing includes an outer ring 1. A retaining upper bracket 3 is provided on one side of the outer ring 1, and multiple ball holders 5 are fixedly connected to the bottom surface of the retaining upper bracket 3. Ball grooves 6 are formed on the side walls of the ball holders 5, and ball balls 7 are rotatably connected to the inner walls of the ball grooves 6. A retaining lower bracket 4 is fixedly connected to the bottom surface of the ball holders 5. First, the balls are placed into the ball grooves 6 of the ball holders 5. Then, the retaining upper bracket 3 and retaining lower bracket 4 are placed inside the outer ring 1. An inner ring 2 is provided on one side of the retaining upper bracket 3 and retaining lower bracket 4. The inner ring 2 is then placed inside the retaining upper bracket 3, thus completing the bearing installation. An outer annular groove 8 is formed on the inner wall of the outer ring 1, and the inner wall of the outer annular groove 8 abuts against the side walls of the ball balls 7. An inner annular groove 9 is formed on the side wall of the inner ring 2, and the inner wall of the inner annular groove 9 abuts against the side walls of the ball balls 7. After the bearing is installed, the outer annular groove 8 and the inner annular groove 9 provide a limiting and fixing function for the steel ball 7. The upper frame 3 has an upper oil reservoir 10 inside, and the lower frame 4 has a lower oil reservoir 11 inside. The bottom surface of the upper oil reservoir 10 and the lower oil reservoir 11 are provided with oil outlet holes 12, and the top of the upper oil reservoir 10 and the lower oil reservoir 11 are provided with oil inlet holes 13. The oil outlet holes 12 are symmetrically arranged with the steel ball 7, so that lubricating oil can be added into the upper oil reservoir 10 through the oil inlet holes 13. During the operation of the bearing, the lubricating oil in the upper oil reservoir 10 will be continuously squeezed out from the upper oil reservoir 10 through the oil outlet holes 12 symmetrically arranged with the steel ball 7, providing lubrication for the rotation of the steel ball 7, avoiding the situation of lubricating oil deficiency, reducing wear, and thus extending the service life of the bearing.

[0029] refer to Figure 2The bottom surface of the upper retainer 3 is fixedly connected to multiple connecting blocks 14. The bottom surface of the connecting blocks 14 is fixedly connected to the surface of the lower retainer 4. The multiple connecting blocks 14 can provide a certain support and fixation for the upper retainer 3 and the lower retainer 4 during the operation of the bearing, improve the rigidity of the upper retainer 3 and the lower retainer 4, reduce the probability of deformation of the upper retainer 3 and the lower retainer 4, and thus extend the service life of the upper retainer 3 and the lower retainer 4, making the use of the bearing more convenient.

[0030] refer to Figure 2 The connecting block 14 has a connecting oil groove 15 inside, and the connecting oil groove 15 is connected to the upper oil storage tank 10 and the lower oil storage tank 11. The setting of the connecting oil groove 15 allows the lubricating oil poured into the upper oil storage tank 10 and the lower oil storage tank 11 to circulate, improve the efficiency, and can store a certain amount of lubricating oil, which is convenient for lubricating the steel ball 7.

[0031] refer to Figure 3 The outer ring 1 has an outer oil groove 16 inside, and an outer oil groove 17 is formed on the side wall of the outer oil groove 16. An outer oil filling hole 18 is formed on the surface of the outer ring 1, and the outer oil filling hole 18 is connected to the outer oil groove 16. The outer oil groove 16, the outer oil groove 17 and the outer oil filling hole 18 are provided so that lubricant can be added to the outer oil groove 16 through the outer oil filling hole 18. When the steel ball 7 rolls along the outer annular groove 8, the lubricant in the outer oil groove 16 will be discharged from the outer oil groove 17, thereby providing lubrication for the steel ball 7 rolling along the outer annular groove 8, reducing the friction between the steel ball 7 and the outer ring 1, reducing wear, and thus extending the service life of the outer ring 1.

[0032] refer to Figure 3 The inner ring 2 has an inner oil groove 19 inside, and an inner oil outlet groove 20 is formed on the side wall of the inner oil groove 19. The inner oil filling hole 21 is formed on the surface of the inner ring 2 and is connected to the inner oil groove 19. The inner oil groove 19, the inner oil outlet groove 20 and the inner oil filling hole 21 are provided so that lubricant can be added to the inner oil groove 19 through the inner oil filling hole 21. When the steel ball 7 rolls along the inner annular groove 9, the lubricant in the inner oil groove 19 will be discharged from the inner oil outlet groove 20, thereby providing lubrication for the steel ball 7 rolling along the inner annular groove 9, reducing the friction between the steel ball 7 and the inner ring 2, reducing wear, and thus extending the service life of the inner ring 2.

[0033] refer to Figure 4 The oil inlet hole 13, the outer oil filling hole 18, and the inner oil filling hole 21 are all tapered, with the top smaller than the bottom. The tapered design of the oil inlet hole 13, the outer oil filling hole 18, and the inner oil filling hole 21 makes it difficult for the lubricating oil in the outer oil groove 16, the inner oil groove 19, and the upper oil storage tank 10 to flow out from the oil inlet hole 13, the outer oil filling hole 18, and the inner oil filling hole 21, thus avoiding waste.

[0034] refer to Figure 4 Both the oil outlet 12 and the external oil groove 17 are tapered, with the inner part being larger than the outer part. The tapered design of the oil outlet 12 and the external oil groove 17 can reduce the amount of lubricating oil discharged from the oil outlet 12 and the external oil groove 17, avoid waste, and thus improve the utilization rate of lubricating oil.

[0035] The implementation principle of the high-speed deep groove ball bearing in this embodiment is as follows: First, the balls are placed into the ball groove 6 of the ball cage 5. Then, the upper retainer 3 and the lower retainer 4 are placed inside the outer ring 1. Next, the inner ring 2 is placed inside the upper retainer 3, thus completing the bearing installation. After the bearing installation is completed, the outer annular groove 8 and the inner annular groove 9 provide a limiting and fixing function for the ball 7. Lubricating oil can be added to the upper oil reservoir 10 through the oil inlet 13. During the operation of the bearing, the lubricating oil in the upper oil reservoir 10 will be continuously squeezed out from the upper oil reservoir 10 through the oil outlet 12 symmetrically arranged with the ball 7, providing lubrication for the rotation of the ball 7, avoiding the situation of lubricating oil deficiency, reducing wear, and thus extending the service life of the bearing.

[0036] The multiple connecting blocks 14 provide support and fixation for the upper retaining frame 3 and the lower retaining frame 4 during bearing operation, thereby increasing the rigidity of the upper retaining frame 3 and the lower retaining frame 4, reducing the probability of deformation of the upper retaining frame 3 and the lower retaining frame 4, and extending the service life of the upper retaining frame 3 and the lower retaining frame 4, and facilitating the use of the bearing.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
