Description

Technical Field

[0001] This utility model relates to the field of angular contact ball bearing technology, specifically an impact-resistant angular contact ball bearing. Background Technology

[0002] Angular contact ball bearings are a type of bearing. The raceways between the inner and outer rings of an angular contact ball bearing are aligned at a certain angle, which allows the balls to contact the raceways in both the radial and axial directions. When a load is applied to the bearing, due to the presence of the contact angle, the bearing can simultaneously withstand radial loads and unidirectional or bidirectional axial loads.

[0003] Traditional angular contact ball bearings often fail under high impact loads due to poor structural strength, such as rolling element detachment, inner and outer ring deformation, or cage damage. Furthermore, traditional cages are generally integrally molded and cannot be disassembled, resulting in poor cage toughness and inconvenience for disassembly and maintenance. Utility Model Content

[0004] To address the problem that traditional angular contact ball bearings are prone to damage and inconvenient to disassemble under impact loads due to their poor toughness, the purpose of this invention is to provide an impact-resistant angular contact ball bearing.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: an impact-resistant angular contact ball bearing, comprising an outer ring, an inner ring at the center of the outer ring, two symmetrically distributed cages slidingly engaged between the outer ring and the inner ring, multiple annular array mounting holes in the center of each of the two cages, rolling elements slidably engaged in the center of each of the multiple mounting holes, and elastic connectors fixedly mounted in the center of each of the two cages, two symmetrically distributed mounting blocks fixedly mounted on one side of one cage, four socket head cap screws slidably engaged in the center of each of the four mounting blocks, two symmetrically distributed limiting blocks fixedly mounted on one side of the other cage, two symmetrically distributed mounting grooves on one side of the other cage, four mounting blocks slidably engaged in the interior of the mounting grooves, four symmetrically distributed threaded grooves on the upper part of one side of the other cage, four socket head cap screws threadedly mounted in the interior of the threaded grooves, and two symmetrically distributed limiting grooves on one side of the other cage, two limiting blocks slidably engaged in the interior of the limiting grooves.

[0006] Preferably, multiple heat sinks arranged in a ring array are fixedly installed on both sides of the two retainers, and multiple heat dissipation holes arranged in a ring array are opened in the middle of the two retainers.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0008] 1. This application enables the cage to be easily removed from between the inner and outer rings by using internal hex bolts. At the same time, the use of elastic connectors allows the cage to have a segmented structure, with each segment connected by elastic connectors to adapt to deformation under impact loads, significantly improving the bearing's impact resistance and load-bearing capacity, and extending its service life.

[0009] 2. This application can dissipate the heat generated by the angular contact ball bearing during normal operation by setting heat sinks and heat dissipation holes, thereby improving the service life of the angular contact ball bearing. Attached Figure Description

[0017] 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.

[0018] Example: Figure 1-5 As shown, this utility model provides an impact-resistant angular contact ball bearing, including an outer ring 1, an inner ring 2 at the center of the outer ring 1, two symmetrically distributed cages 3 slidingly engaged between the outer ring 1 and the inner ring 2, multiple annular array mounting holes 34 opening in the center of each of the two cages 3, rolling elements 33 slidingly engaged in the center of each of the multiple mounting holes 34, elastic connectors 39 fixedly mounted in the center of each of the two cages 3, and two symmetrically distributed mounting blocks 37 fixedly mounted on one side of one of the cages 3, with four mounting blocks 37 slidingly engaged in the center of each of the four mounting blocks 37. The retainer 3 has two symmetrically distributed limiting blocks 38 fixedly installed on one side, and two symmetrically distributed mounting grooves 371 opened on one side of the other retainer 3. All four mounting blocks 37 are slidably engaged inside the mounting grooves 371. All four symmetrically distributed threaded grooves 361 are opened on the upper part of one side of the other retainer 3. All four hexagon socket head cap screws 36 are threadedly installed inside the threaded grooves 361. All two symmetrically distributed limiting grooves 381 are opened on one side of the other retainer 3. All two limiting blocks 38 are slidably engaged inside the limiting grooves 381.

[0019] Multiple heat sinks 31 arranged in a ring array are fixedly installed on both sides of the two retainers 3, and multiple heat dissipation holes 32 arranged in a ring array are opened in the middle of the two retainers 3. By setting heat sinks 31 and heat dissipation holes 32, the heat dissipation performance of the bearing is improved.

[0020] Two symmetrically distributed first reinforcing ribs 11 are fixedly installed in the middle of the outer ring 1. By setting the first reinforcing ribs 11, the impact resistance of the angular contact ball bearing is improved.

[0021] The outer ring 1 and the inner ring 2 are provided with guide grooves 12 on the opposite sides of the middle. The multiple rolling elements 33 are slidably locked inside the guide grooves 12. By setting the guide grooves 12, the stable movement of the rolling elements 33 in the guide grooves 12 is ensured.

[0022] Two symmetrically distributed second reinforcing ribs 21 are fixedly installed in the middle of the inner ring 2. By setting the second reinforcing ribs 21, the structural strength of the inner ring 2 is improved.

[0023] Both of the cages 3 are fixedly installed with a third reinforcing rib 35 on their upper parts. By setting the third reinforcing rib 35, the structural stability of the cage 3 is improved.

[0024] An elastic rubber layer 333 is fixedly installed in the middle of the rolling element 33, and a wear-resistant alloy layer 332 is fixedly installed on the outer side of the elastic rubber layer 333. By setting the elastic rubber layer 333 and the wear-resistant alloy layer 332, the rolling element 33 is arranged in a double layer, with the outer layer being a high-strength wear-resistant alloy and the inner layer being an elastic rubber material, so as to absorb impact and reduce wear.

[0025] The outer surface of the wear-resistant alloy layer 332 is provided with a lubricating coating 331, which is in contact with the guide groove 12. By providing the lubricating coating 331, the rolling element 33 has a self-lubricating function, thereby reducing the coefficient of friction and improving wear resistance.

[0026] Working principle: In actual use, the internal hex bolt 36 is rotated to remove it from the threaded groove 361, thereby releasing the limiting position of the two cages 3. By pulling along the limiting groove 381, the limiting block 38 is moved away from the limiting groove 381, thereby separating the two cages 3 from each other, making it easy to remove the cages 3 from between the inner ring 2 and the outer ring 1. During use, the outermost lubricating coating 331 of the rolling element 33 reduces the coefficient of friction and improves wear resistance. Furthermore, the heat sink 31 and heat dissipation holes 32 improve the heat dissipation performance of the bearing.

[0027] 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.
