Description

Technical Field

[0001] This application relates to the field of bearing technology, and more specifically, to an anti-slip bearing. Background Technology

[0002] Bearings are critical components widely used in the mechanical field. Their main function is to support rotating mechanical parts, reduce the coefficient of friction during rotation, and ensure the rotational accuracy of the shaft. By providing suitable interfaces and constraints between relatively moving parts, they enable the shaft to rotate smoothly and stably, reducing energy loss, wear, and heat generation caused by friction. Bearings generally consist of an inner ring, an outer ring, rolling elements (such as balls and rollers), and a cage.

[0003] Existing ball bearings are generally limited only by cages. However, when subjected to huge axial and radial loads, the balls rotate at high speeds, and the force distribution of the balls in the cage becomes extremely complex and uneven. This can easily lead to irregular slippage of the balls in the cage, disrupting the original stable rolling state inside the bearing. Once slippage occurs, it will increase frictional losses and cause a significant increase in bearing vibration and noise. Noise will not only affect the smoothness of equipment operation, but will also be transmitted to other parts of the equipment, causing a series of derivative problems such as loose connections and structural fatigue, posing a serious threat to the structural integrity and reliability of the entire equipment. Utility Model Content

[0004] To address the aforementioned problems, this application provides an anti-slip bearing.

[0005] The anti-slip bearing provided in this application adopts the following technical solution:

[0006] An anti-slip bearing includes an outer ring and an inner ring, with a plurality of balls disposed between the outer ring and the inner ring. Limiting channels are provided on the side of the outer ring and the inner ring near the balls. Cages are provided on the outer walls of the plurality of balls, and a reinforcing component is provided on one side of each cage.

[0007] The reinforcing assembly includes two reinforcing rings, which are located on opposite sides of the corresponding cage. Each pair of cages is used to limit the balls and prevent slippage.

[0008] Furthermore, each reinforcing ring is provided with a connecting rod between it and the corresponding cage. The number of connecting rods is set to multiple, and the multiple connecting rods are evenly distributed between the corresponding cage and the reinforcing ring.

[0009] Furthermore, each cage has connecting blocks on both sides, and reinforcing ribs are provided between every two balls.

[0010] Furthermore, each reinforcing rib has multiple bolts on one side, and every two connecting blocks are fixedly connected to the corresponding reinforcing rib by multiple bolts.

[0011] Furthermore, the inner diameter of each reinforcing ring is smaller than the diameter of the ball.

[0012] The above technical solutions effectively enhance the stability of the cage under high-speed operation and reduce deformation and displacement caused by ball impact and centrifugal force.

[0013] Furthermore, each reinforcing ring is equipped with lubricating cotton inside, and each lubricating cotton is in contact with the outer wall of the corresponding ball.

[0014] Furthermore, each reinforcing ring has an oil storage cavity inside, and each reinforcing ring has an oil injection hole on one side, with each oil injection hole connected to the corresponding oil storage cavity.

[0015] Furthermore, each reinforcing ring has multiple perforations on its inner wall, and these perforations are evenly distributed.

[0016] The above technical solution can reduce friction between the ball and the roller.

[0017] In summary, this application includes at least one of the following beneficial technical effects:

[0018] (1) This utility model effectively enhances the stability of the cage under high-speed operation by strengthening the components, reduces the deformation and displacement caused by ball impact and centrifugal force, ensures the accuracy of the ball movement trajectory, limits the abnormal shaking between the balls by setting the reinforcing ribs, optimizes the ball distribution state, makes the force transmission more uniform, reduces the risk of local stress concentration, and the reinforcing ring not only strengthens the cage structure, but its smaller inner diameter can also prevent the balls from slipping at critical moments, greatly improves the overall anti-slipping ability of the bearing, thereby reducing the friction loss, wear aggravation and temperature rise caused by slipping, extending the service life of the bearing, improving the reliability and stability of equipment operation, and reducing maintenance costs and downtime risks;

[0019] (2) This utility model can reduce the friction between the lubricating cotton and the ball, and also ensure that the lubricating oil is continuously and evenly distributed on the surface of the ball. When the bearing is running, the lubricating oil can be replenished through the oil injection hole in time, stored in the oil storage cavity, and then permeated to the lubricating cotton through the leakage hole, so as to maintain a good lubrication state. This is conducive to further stabilizing the rolling of the ball, reducing the jamming or slipping caused by insufficient lubrication, and also can carry away some of the heat generated during operation, playing a certain heat dissipation role, thereby extending the service life of the bearing.

[0026] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0027] Reference Figures 1-4 An anti-slip bearing includes an outer ring 1 and an inner ring 2, with a plurality of balls 3 disposed between the outer ring 1 and the inner ring 2. Limiting channels 4 are provided on the side of the outer ring 1 and the inner ring 2 near the balls 3. A retainer 5 is provided on the outer wall of the plurality of balls 3, and a reinforcing component is provided on one side of each retainer 5.

[0028] The reinforcing component includes two reinforcing rings 9, which are located on both sides of the corresponding cage 5. Each pair of cages 5 is used to limit the movement of the balls 3 and prevent slippage.

[0029] Reference Figures 1-4 Each reinforcing ring 9 is provided with a connecting rod 10 between it and the corresponding retainer 5. The number of connecting rods 10 is set to multiple, and the multiple connecting rods 10 are evenly distributed between the corresponding retainer 5 and the reinforcing ring 9. Each retainer 5 is provided with a connecting block 6 on both sides. A reinforcing rib 7 is provided between every two balls 3. Each reinforcing rib 7 is provided with multiple bolts 8 on one side. Every two connecting blocks 6 are fixedly connected to the corresponding reinforcing rib 7 by multiple bolts 8. The inner diameter of each reinforcing ring 9 is smaller than the diameter of the ball 3.

[0030] By strengthening the components, slippage of the ball 3 can be prevented when it rotates at high speed. Specifically, when the bearing starts to run and the ball 3 rotates at high speed, the ball 3 will generate a large impact force and centrifugal force on the cage 5. At this time, the reinforcing rings 9 on both sides of the cage 5 provide a stable support force to the cage 5 through multiple evenly distributed connecting rods 10, limiting the deformation and displacement of the cage 5. At the same time, the reinforcing ribs 7 between adjacent balls 3 are tightly fixed to the cage 5 through connecting blocks 6 and bolts 8, further enhancing the structural strength of the cage 5. The reinforcing ribs 7 can effectively limit the excessive shaking and deviation of the ball 3 in adjacent positions, so that the ball 3 always stays on a relatively stable rolling path. Since the inner diameter of the two reinforcing rings 9 is smaller than the diameter of the ball 3, when the ball 3 attempts to slip or deviate from the normal rolling trajectory, it can promptly block and correct the ball 3, ensuring that the ball 3 rolls stably during high-speed operation and avoiding slippage, thereby ensuring the normal and efficient operation of the entire bearing.

[0031] By strengthening the components, the stability of the cage 5 under high-speed operation is effectively enhanced, reducing deformation and displacement caused by the impact and centrifugal force of the balls 3, ensuring the accuracy of the ball 3's movement trajectory. The setting of the reinforcing ribs 7 limits abnormal shaking between the balls 3, optimizes the distribution of the balls 3, makes the force transmission more uniform, and reduces the risk of local stress concentration. In addition, the reinforcing ring 9 not only strengthens the structure of the cage 5, but its smaller inner diameter can also prevent the balls 3 from slipping at critical moments, greatly improving the overall anti-slip capability of the bearing. This reduces friction loss, increased wear, and temperature rise caused by slippage, extends the bearing's service life, improves the reliability and stability of equipment operation, and reduces maintenance costs and downtime risks.

[0032] Reference Figure 5 Each reinforcing ring 9 has a lubricating cotton 12 inside, and each lubricating cotton 12 is in contact with the outer wall of the corresponding ball 3. Each reinforcing ring 9 has an oil storage cavity 11 inside, and each reinforcing ring 9 has an oil injection hole 14 on one side, and each oil injection hole 14 is connected to the corresponding oil storage cavity 11. Each reinforcing ring 9 has multiple leakage holes 13 on its inner wall, and the multiple leakage holes 13 are evenly distributed.

[0033] The lubricating cotton 12 reduces friction between the ball and the ball 3 and ensures that the lubricating oil is continuously and evenly distributed on the surface of the ball 3. During bearing operation, lubricating oil can be added in time through the oil filling hole 14 and stored in the oil reservoir 11. It then permeates to the lubricating cotton 12 through the drain hole 13, always maintaining a good lubrication state. This helps to further stabilize the rolling of the ball 3, reduce jamming or slippage caused by insufficient lubrication, and also remove some of the heat generated during operation, playing a certain heat dissipation role, thereby extending the service life of the bearing.

[0034] Working principle: First, when the bearing starts to run and the balls 3 rotate at high speed, the balls 3 will generate a large impact force and centrifugal force on the cage 5. At this time, the reinforcing rings 9 on both sides of the cage 5 provide a stable support force to the cage 5 through multiple evenly distributed connecting rods 10, limiting the deformation and displacement of the cage 5. At the same time, the reinforcing ribs 7 between adjacent balls 3 are tightly fixed to the cage 5 through connecting blocks 6 and bolts 8, further enhancing the structural strength of the cage 5. The reinforcing ribs 7 can effectively limit the excessive shaking and deviation of the balls 3 in adjacent positions, so that the balls 3 always keep on a relatively stable rolling path. Since the inner diameter of the two reinforcing rings 9 is smaller than the diameter of the balls 3, when the balls 3 attempt to slip or deviate from the normal rolling trajectory, they can promptly block and correct the balls 3, ensuring that the balls 3 roll stably during high-speed operation and avoiding slippage, thereby ensuring the normal and efficient operation of the entire bearing.

[0035] 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.
