Description

Technical Field

[0001] This utility model relates to the field of deep groove ball bearings, and in particular to a deep groove ball bearing that facilitates the installation of a sealing ring. Background Technology

[0002] Deep groove ball bearings, as a widely used mechanical component, are extensively applied in various fields such as motors, automobiles, and mechanical equipment due to their advantages such as simple structure, high load-bearing capacity, and long service life. However, with the increasing complexity of industrial production and application environments, deep groove ball bearings face many challenges in actual use, especially the sealing performance issue.

[0003] Traditional deep groove ball bearings typically employ a simple sealing design, relying primarily on seals to prevent the intrusion of external contaminants such as dust and moisture. However, these traditional sealing structures suffer from defects such as inadequate sealing, poor wear resistance, and difficult installation, leading to rapid failure of the internal grease and thus affecting the normal operation and service life of the bearing.

[0004] In many industrial applications, the intrusion of external contaminants such as dust, dirt, and moisture can significantly reduce bearing performance, leading to increased friction, higher temperatures, and even bearing damage. Existing seals are not sufficiently effective at sealing the rolling clearance between the inner and outer rings of a bearing, especially under high-speed operation or harsh environments, allowing dust and contaminants to still penetrate the bearing. Therefore, improving the sealing performance of deep groove ball bearings has become an important research direction in the field of bearing design and manufacturing. Utility Model Content

[0036] 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.

[0037] This utility model provides, for example Figure 1-4The deep groove ball bearing shown is easy to install with a seal ring, comprising: a deep groove ball bearing body; and a seal ring installed on both sides of the deep groove ball bearing body, which is used to isolate the deep groove ball bearing body from the external environment. The seal ring includes: a skeleton 4 and a sealing structure 5. The skeleton 4 is embedded inside the sealing structure 5 and is used to provide shaping support for the sealing structure 5. The sealing structure 5 is used to seal and isolate the deep groove ball bearing body.

[0038] The deep groove ball bearing body includes: an outer ring 1, which is annular; an inner ring 2, which is fitted inside the outer ring 1, and there is a rolling clearance between the outer wall of the inner ring 2 and the inner wall of the outer ring 1; and a ball 3, which is rolled between the outer ring 1 and the inner ring 2, and a cage is provided on the outside of the ball 3 to make the rolling of the ball 3 more stable.

[0039] The sealing structure 5 includes: a connecting component 51, which is embedded in one side of the frame 4; a first sealing component 52, which is connected to the outer ring of the connecting component 51, with first mounting grooves 101 on both sides of the inner wall of the bearing outer ring 1, the first sealing component 52 and the inner cavity of the first mounting grooves 101 cooperating to facilitate the positioning of the first sealing component 52; and a second sealing component 53, which is connected to the inner ring of the connecting component 51, with second mounting grooves 201 on both sides of the outer side of the bearing inner ring 2. The first sealing component 52 cooperates with the inner cavity of the second assembly groove 201 to facilitate the positioning of the second sealing component 53. The first sealing component 52 facilitates the positioning and sealing of the bearing outer ring 1 and the bearing inner ring 2. Thus, the cooperation between the connecting component 51, the first sealing component 52 and the second sealing component 53 can isolate the rolling gap between the bearing outer ring 1 and the bearing inner ring 2 from the external environment, preventing a large amount of dust from entering the deep groove ball bearing and greatly improving the sealing performance of the deep groove ball bearing.

[0040] The first assembly groove 101 has a positioning ring 11 connected to its inner wall. The first sealing assembly 52 has an annular groove 501 that mates with the positioning ring 11. The inner wall of the annular groove 501 has wavy protrusions at the contact point between the positioning rings 11, which facilitates mutual contact with the positioning rings 11 to form multiple seals. Through the mutual cooperation between the positioning rings 11 and the inner cavity of the annular groove 501, the positioning rings 11 can be used to position the first sealing assembly 52. ​​This allows the sealing ring to be accurately positioned relative to the outer ring 1 of the bearing during installation, avoiding sealing failure and reducing maintenance costs and replacement frequency.

[0041] Specifically, the connecting component 51 includes: a connecting part 511, which is connected to one side of the frame 4; and an insert part 512, which is connected to one side of the connecting part 511 and is embedded inside the frame 4. The insert part 512 is arranged in a figure-eight shape. Through the integrated arrangement between the insert part 512 and the connecting part 511, and the fact that the insert part 512 is embedded in the frame 4 in a figure-eight shape, the gripping force between the connecting component 51 and the frame 4 is improved, and the connecting component 51 is prevented from falling directly off the outside of the frame 4. The first sealing component 52 includes: an edge-wrapping portion 521, the outer ring of the skeleton 4 is provided with a flange, the edge-wrapping portion 521 is wrapped around the outside of the flange, and the edge-wrapping portion 521 is integrally formed with the connecting portion 511; and a locking portion 522, the locking portion 522 is hook-shaped and engages with the inside of the first assembly groove 101, and the edge-wrapping portion 521 is integrally formed with the locking portion 522, and the corner of the locking portion 522 is provided with a chamfer, so as to facilitate the installation and engagement of the connecting component 51 with the relative position of the first assembly groove 101. Through the fit between the inner wall of the edge-wrapping portion 521 and the locking portion 522, the inner cavity of the first assembly groove 101 is easily sealed. The second sealing assembly 53 includes: a first sealing lip 531, which is snapped into the interior of the second mounting groove 201 and is integrally formed with the connecting portion 511; a second sealing lip 532, which is disposed on one side of the first sealing lip 531 and is integrally formed with the first sealing lip 531; and an elastic ring 533, which is sleeved on the first sealing lip 531 and is used to elastically tighten the first sealing lip 531. The first sealing lip 531 has a triangular cross-section, and its head is aligned with the second mounting groove 201. The inner walls fit together, and the first sealing lip 531 and the second sealing lip 532 fit together with the inner wall of the second assembly groove 201, thus facilitating the sealing of the inner cavity of the second assembly groove 201. The elastic ring 533 is made of rubber. When the elastic ring 533 is fitted on the first sealing lip 531, it is in an elastically stretched state. Through the elastic deformation of the elastic ring 533, it is easy to tighten the first sealing lip 531 inward, so that the fit between the first sealing lip 531 and the inner cavity of the second assembly groove 201 is better. It can effectively prevent the intrusion of external contaminants when the bearing rotates, and significantly improve the sealing performance and service life of the deep groove ball bearing.
