[0002] The line of the roller and the contact point of the inner and outer rings of the angular contact ball bearing forms an angle with the radial direction, and the contact angle is generally 15°, 30° or 40°. The angular contact ball bearing mainly bears large unidirectional axial load. The greater the contact angle, the greater the load-bearing capacity. The cage material is steel plate, brass or engineering plastic. The forming method is stamping or turning. Depending on the bearing type or use conditions, other options include combined angular contact ball bearings, double-row angular contact ball bearings and four-point contact ball bearings.

[0003] However, the angular contact bearing in the prior art still has some defects:

If the bearing operates for a long time without lubrication, the service life of the roller is greatly affected, and the transmission efficiency is also affected. SUMMARY

[0022] 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.

[0023] Example: Figures 1-5 As shown, this utility model provides a thin-walled angular contact ball bearing. The angular contact bearing includes an outer ring 1, an inner ring 2, a cage 3, and rollers 4. The inner ring 2 is disposed inside the outer ring 1, and the cage 3 is disposed between the inner ring 2 and the outer ring 1. An anti-slip ring 21 is fixedly disposed on the inner wall of the inner ring 2. By providing the anti-slip ring 21, when the inner ring 2 is fixed on the external drive shaft, the anti-slip ring 21 can improve the stability between the inner ring 2 and the external drive shaft and reduce the wear of the inner ring 2 and the external drive shaft. The cage 3 has a plurality of pockets 31 distributed in an annular array. The rollers 4 are disposed in the pockets 31. The outer ring 1 is provided with a lubrication assembly 5. By providing the lubrication assembly 5, the lubrication assembly 5 can lubricate the rollers 4 during operation, thereby improving the service life and transmission efficiency of the angular contact bearing.

[0024] The lubrication assembly 5 includes an oil reservoir 51, which has an arc-shaped cavity structure. This arc-shaped cavity allows lubricating oil to be stored within the oil reservoir 51. Simultaneously, the lubricating oil stored in the oil reservoir 51 flows downwards towards the center due to gravity. The oil reservoir 51 is integrally formed on the outer ring 1. A filling pipe 52 is located above the center of the oil reservoir 51, facilitating the addition of lubricating oil by operators. A discharge port is located below the center of the oil reservoir 51. Pipe 53 and discharge pipe 53 are vertically aligned with roller 4. By setting discharge pipe 53, lubricating oil in oil reservoir 51 can be discharged downward through discharge pipe 53 and fall onto roller 4. One end of filling pipe 52 is detachably equipped with a plug 54. By setting plug 54, the opening and closing of filling pipe 52 can be controlled. A strainer 55 is fixedly set inside discharge pipe 53. By setting strainer 55, strainer 55 can reduce the downward flow speed of lubricating oil in discharge pipe 53 and prevent lubricating oil from being wasted due to excessive downward flow speed.

[0025] The outer ring 1 has several threaded holes 11 arranged in a ring array. The internal threads of the threaded holes 11 are rotatably installed with fixing bolts 12. The two outer rings 1 can be detachably spliced ​​together through the threaded holes 11 and fixing bolts 12. By setting the threaded holes 11 and fixing bolts 12, the two outer rings 1 can be assembled together. When the two outer rings 1 are assembled together, the support performance of the angular contact bearing is improved and the vibration when the external drive shaft rotates is reduced.

[0026] Working principle: When this angular contact bearing is in use, the two outer rings 1 are first assembled together through the cooperation of multiple threaded holes 11 and multiple fixing bolts 12. When the external drive shaft passes through the inner ring 2, the support performance of the angular contact bearing is improved and the vibration of the external drive shaft is reduced during rotation.

[0027] Before the external drive shaft rotates, the operator first removes the plug 54 and adds lubricating oil into the oil reservoir 51 through the filling pipe 52. Then, the plug 54 is fastened onto the filling pipe 52. When the external drive shaft rotates, the external drive shaft and the inner ring 2 rotate synchronously, and multiple rollers 4 revolve. At the same time, the lubricating oil in the oil reservoir 51 passes through the strainer 55 and the discharge pipe 53 and falls onto the multiple rollers 4. The lubricating oil discharged downwards lubricates the multiple rollers 4, thus conveniently realizing the self-lubrication of the angular contact bearing during the working process, thereby effectively improving the service life and transmission efficiency of the angular contact bearing.

[0028] 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.
