Description

Technical Field

[0001] This utility model mainly relates to the field of bearing rings, and specifically to a bearing ring. Background Technology

[0002] Bearings are crucial basic components in modern mechanical equipment. Their core function is to support rotating mechanical parts, reduce the coefficient of friction during movement, and ensure rotational accuracy. Bearings typically consist of four parts: an inner ring, an outer ring, rolling elements (such as balls and rollers), and a cage. The raceways of the bearing rings (i.e., the inner and outer rings) directly contact the rolling elements, and their design, materials, and manufacturing processes directly determine the bearing's performance, lifespan, and reliability.

[0003] In the traditional manufacturing and assembly of deep groove ball bearings, the inner and outer rings are typically integral structures. While this integrated design ensures structural integrity and strength, it presents significant technical challenges when assembling the last ball. Due to radial clearance limitations, the assembler must forcefully offset the inner and outer rings radially to squeeze in the final ball. This process usually requires specialized equipment or tooling fixtures to apply considerable force, resulting in low assembly efficiency and a high risk of surface damage such as scratches and indentations on the balls or raceway. These minute damages become stress concentration points during subsequent high-speed bearing operation, accelerating fatigue wear, leading to increased bearing noise, intensified vibration, and ultimately shortening its service life. Utility Model Content

[0004] 1. The technical problem to be solved by the utility model:

[0005] This utility model provides a bearing ring to solve the technical problems existing in the background art.

[0006] 2. Technical Solution:

[0007] To achieve the above objectives, the technical solution provided by this utility model is as follows: a bearing ring, including an outer ring structure, an inner ring structure is provided on the inner side of the outer ring structure, and tension fixing structures are provided on both sides of the inner wall of the outer ring structure.

[0008] A tension fixing structure includes a first elastic plate, with insertion shafts at both ends of the first elastic plate, and a second elastic strip on the inner side of the first elastic plate. The number of the second elastic strips is set to two, and the two second elastic strips are symmetrically distributed at the top and bottom of the first elastic plate.

[0009] Furthermore, the outer ring structure includes an outer ring body, and the number of outer ring bodies is set to two. One outer ring body has slots at both ends, and the other outer ring body has inserts at both ends. The outer ring body and the inserts cooperate with each other.

[0010] Furthermore, an installation strip is provided on the inner side of the outer ring body, and ball bearing placement grooves are provided on the top and bottom of the inner wall of the outer ring body.

[0022] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of the utility model will be more thorough and complete.

[0023] Reference Figures 1-4 A bearing ring includes an outer ring structure 1, an inner ring structure 3 is provided on the inner side of the outer ring structure 1, and tension fixing structures 2 are provided on both sides of the inner wall of the outer ring structure 1.

[0024] The tension fixing structure 2 includes a first elastic plate 201, with insert shafts 203 at both ends of the first elastic plate 201. A second elastic strip 202 is provided on the inner side of the first elastic plate 201. The number of the second elastic strips 202 is set to two, and the two second elastic strips 202 are symmetrically distributed on the top and bottom of the first elastic plate 201. When the ball is installed between the outer ring body 101 and the inner ring structure 3, the tension fixing structure 2 is installed between the two outer ring bodies 101. At the same time, the outer ring body 101 is pulled outward to overcome the elasticity of the first elastic plate 201 and the second elastic strip 202. After the ball is installed, the outer ring body 101 is released, and then the elasticity of the first elastic plate 201 and the second elastic strip 202 pulls the two outer ring bodies 101 together.

[0025] The insertion hole 106 is inclined inward, and after the insertion shaft 203 is connected to the insertion hole 106, the two are engaged with each other. At the same time, the insertion hole 106 penetrates the base layer 107, and one end of the insertion hole 106 has a threaded hole. Then, the bolt is inserted into the threaded hole of the insertion hole 106, and the bolt is located inside the outer ring body 101 to avoid affecting the installation of the outer ring body 101.

[0026] Furthermore, the outer ring structure 1 includes an outer ring body 101, of which two outer ring bodies 101 are provided. One outer ring body 101 has slots 102 at both ends, and the other outer ring body 101 has inserts 103 at both ends. The outer ring body 101 and the inserts 103 cooperate with each other. An installation strip 104 is provided on the inner side of the outer ring body 101. Ball placement grooves 105 are provided at the top and bottom of the inner wall of the outer ring body 101. Insertion holes 106 are provided on both sides of the installation strip 104. The inner wall of the insertion hole 106 is connected to the outer side of the insertion shaft 203. The outer ring body 101 is connected to the wall. It includes a base layer 107. The outer wall of the base layer 107 is provided with a corrosion-resistant layer body 108. The insertion hole 106 penetrates the base layer 107. When it is necessary to install a ball between the outer ring structure 1 and the tension fixing structure 2, the ball is placed on the outer wall of the inner ring structure 3. Then, when the two outer ring bodies 101 are spliced ​​together, the insert 103 is inserted into the slot 102 so that the two outer ring bodies 101 are spliced ​​together. After that, the inner wall of the ball placement groove 105 fits against the outer wall of the ball, thereby completing the installation and fixing of the ball.

[0027] Preparation phase:

[0028] Place the inner ring structure 3 of the ring on the worktable;

[0029] The balls are placed sequentially in the ball placement groove 105 between the inner ring structure 3 and the outer ring body 101 of the ring;

[0030] Outer ring docking:

[0031] The two outer ring bodies 101 are connected to the slots 102 via inserts 103 to initially close them;

[0032] Install tension fixing structure 2:

[0033] Align the insertion shaft 203 of the tension fixing structure 2 with the insertion hole 106 on the mounting strip 104;

[0034] Slightly pull the two outer ring bodies 101 outward to overcome the elasticity of the first elastic plate 201 and the second elastic strip 202, so that the insertion shaft 203 is inserted into the insertion hole 106.

[0035] Fixing and locking:

[0036] Loosen the outer ring body 101; the elastic restoring force makes it fit tightly.

[0037] Optional: The insert shaft 203 can be further tightened through the threaded hole with bolts to enhance stability;

[0038] Assembly complete:

[0039] Check that the rollers are evenly distributed and free from compression or misalignment;
