Description

Technical Field

[0001] This utility model relates to the field of angular contact ball bearing technology, specifically a high load-bearing angular contact ball bearing. Background Technology

[0002] Angular contact ball bearings can withstand both radial and axial loads simultaneously. They can operate at high speeds. The larger the contact angle, the higher the axial load capacity. The contact angle is the angle between the line connecting the contact points of the ball and raceway in the radial plane and the perpendicular line to the bearing axis. High-precision and high-speed bearings typically use a 15-degree contact angle. Under axial force, the contact angle will increase.

[0003] However, existing angular contact ball bearings do not have an automatic lubrication effect during use. Generally, lubricant is sprayed or injected before use, but after a long period of use, the balls wear out due to friction, requiring the bearing to stop to check the lubricant status and perform maintenance or add new lubricant, which increases the workload of workers. In order to solve the above problems, the inventors have proposed a high load-bearing angular contact ball bearing. Utility Model Content

[0004] To address the problem of angular contact ball bearings lacking self-lubrication during use, the purpose of this invention is to provide a high-load-bearing angular contact ball bearing.

[0005] To solve the above technical problems, this utility model adopts the following technical solution: a high load-bearing angular contact ball bearing, comprising a bearing body, the bearing body including an outer ring, a cage provided inside the outer ring, balls provided inside the cage, an inner ring provided inside the cage, the balls fixed inside the outer ring and the inner ring, a rolling groove provided inside the inner ring, the balls rolling in the rolling groove, an oil reservoir provided inside the outer ring, an oil injection groove provided inside the outer ring, the oil reservoir and the oil injection groove communicating with each other, a conveying groove provided inside the outer ring, the oil reservoir and the conveying groove communicating with each other, a rotating rod fixedly provided inside the conveying groove, a blocking ball fixedly sleeved on the outer surface of the rotating rod, firstly, lubricant is conveyed from the sleeve in the oil injection groove to the oil reservoir, and then lubricant is conveyed from the conveying groove, the conveying groove is inclined, when passing the blocking ball, it causes the lubricant to be pushed... The moving stop ball rotates within the rotating rod, causing lubricant to slowly drip onto the surface of the balls. This automatically adds lubricant to the balls as they wear down during operation, eliminating the need for periodic lubrication and reducing worker workload. It also increases the bearing's load-bearing capacity. The threaded column is then inserted into the threaded groove, allowing the cover plate and sealing gasket to fit tightly together, sealing the sleeve in the oil reservoir and preventing lubricant leakage. The first and second sealing rings seal the outer ring, cage, and inner ring, preventing dust and impurities from reaching the ball surface and reducing damage. A fixing groove within the first sealing ring facilitates ball heat dissipation, while a dust filter prevents dust from entering the bearing body through the fixing groove.

[0006] Preferably, a sleeve is fixedly provided inside the oil injection groove, a threaded post is threadedly connected inside the sleeve, a cover plate is fixedly provided on the top surface of the threaded post, a sealing gasket is fixedly provided on the top surface of the sleeve, the cover plate is tightly fitted to the top surface of the sealing gasket, a threaded groove is opened inside the sleeve, and the threaded post is threadedly inserted into the threaded groove.

[0007] Preferably, a first sealing ring is fixedly provided on the inner wall of the outer ring, the inner wall of the first sealing ring is fixedly connected to the outer surface of the cage, a fixing groove is provided in the first sealing ring, a dustproof net is fixedly provided in the fixing groove, and a second sealing ring is fixedly provided on the inner wall of the cage, the inner wall of the second sealing ring is fixedly connected to the outer surface of the inner ring.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0009] 1. In this utility model, lubricant is conveyed from the conveying trough through an inclined conveying trough. When the lubricant passes the blocking ball, it causes the lubricant to push the blocking ball, causing the blocking ball to rotate inside the rotating rod. This allows the lubricant to slowly drip onto the surface of the ball, automatically adding lubricant to the ball when it is worn during rotation. This eliminates the need to stop and add lubricant periodically, reducing the workload of workers and improving the bearing capacity of the bearing body.

[0010] 2. In this utility model, the outer ring, cage and inner ring can be sealed by the first sealing ring and the second sealing ring to prevent dust and impurities from drifting to the surface of the ball and reduce the damage to the ball. Attached Figure Description

[0019] 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.

[0020] Example: Figure 1-6 As shown, this utility model provides a high load-bearing angular contact ball bearing, including a bearing body 1. The bearing body 1 includes an outer ring 11, a cage 12 inside the outer ring 11, balls 13 inside the cage 12, and an inner ring 111 inside the cage 12. The balls 13 are fixed in the outer ring 11 and the inner ring 111. A rolling groove 112 is formed in the inner ring 111, and the balls 13 roll in the rolling groove 112. An oil reservoir 101 and an oil filling groove 102 are formed in the outer ring 11, and the oil reservoir 101 and the oil filling groove 102 are interconnected. A conveying groove 103 is formed in the outer ring 11, and the oil reservoir 101 and the conveying groove 103 are interconnected. A rotating rod 3 is fixedly installed inside, and a blocking ball 31 is fixedly sleeved on the outer surface of the rotating rod 3. The lubricant is transported from the sleeve 32 in the oil filling groove 102 to the oil storage groove 101, and then transported from the conveying groove 103. The conveying groove 103 is inclined. When it passes the blocking ball 31, the lubricant causes the blocking ball 31 to push the blocking ball 31, causing the blocking ball 31 to rotate inside the rotating rod 3, so that the lubricant slowly drips onto the surface of the ball 13. Thus, during use, when the ball 13 is worn out by rotation, the lubricant is automatically added to the ball 13, so that there is no need to stop and add lubricant at regular intervals, which reduces the labor intensity of workers and improves the load-bearing capacity of the bearing body 1.

[0021] A sleeve 32 is fixedly installed inside the oil filling groove 102. A threaded post 35 is threadedly connected inside the sleeve 32. A cover plate 34 is fixedly installed on the top surface of the threaded post 35. A sealing gasket 33 is fixedly installed on the top surface of the sleeve 32. The cover plate 34 is tightly fitted to the top surface of the sealing gasket 33. A threaded groove 321 is opened inside the sleeve 32. The threaded post 35 is threadedly inserted into the threaded groove 321.

[0022] By adopting the above technical solution, the threaded column 35 is threaded into the threaded groove 321, thereby enabling the cover plate 34 and the sealing gasket 33 to fit tightly together, thus sealing the sleeve 32 in the oil filling groove 102 and preventing the lubricant in the oil storage groove 101 from leaking out.

[0023] A first sealing ring 2 is fixedly provided on the inner wall of the outer ring 11. The inner wall of the first sealing ring 2 is fixedly connected to the outer surface of the retainer 12. A fixing groove 201 is provided in the first sealing ring 2. A dustproof net 22 is fixedly provided in the fixing groove 201. A second sealing ring 21 is fixedly provided on the inner wall of the retainer 12. The inner wall of the second sealing ring 21 is fixedly connected to the outer surface of the inner ring 111.

[0024] By adopting the above technical solution, the outer ring 11, the cage 12 and the inner ring 111 can be sealed by the first sealing ring 2 and the second sealing ring 21, so as to prevent dust and impurities from drifting to the surface of the ball 13 and reduce the damage to the ball 13. At the same time, the fixing groove 201 opened in the first sealing ring 2 facilitates the heat dissipation of the ball 13, and the dustproof net 22 provided prevents dust from entering the bearing body 1 from the fixing groove 201.

[0025] Working principle: First, lubricant is transported from the sleeve 32 in the oil filling tank 102 to the oil storage tank 101. Then, lubricant is transported from the conveying tank 103, which is inclined. When it passes the blocking ball 31, the lubricant pushes the blocking ball 31, causing it to rotate within the rotating rod 3. This allows the lubricant to slowly drip onto the surface of the ball 13. Thus, during use, when the ball 13 experiences wear due to rotation, lubricant is automatically added to the ball 13, eliminating the need for periodic stops to add lubricant, reducing the workload of workers, and simultaneously improving the load-bearing capacity of the bearing body 1. Then, the threaded column 35 is threaded into the threaded... The groove 321 allows the sleeve 32 to be tightly fitted, thereby sealing the sleeve 32 in the oil filling groove 102 and preventing lubricant leakage from the oil reservoir 101. The first sealing ring 2 and the second sealing ring 21 can seal the outer ring 11, the cage 12 and the inner ring 111, preventing dust and impurities from drifting to the surface of the ball 13 and reducing damage to the ball 13. At the same time, the fixing groove 201 in the first sealing ring 2 facilitates heat dissipation of the ball 13, and the dustproof net 22 prevents dust from entering the bearing body 1 from the fixing groove 201.

[0026] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
