Description

Technical Field

[0001] This utility model relates to the field of bearing sealing ring technology, and in particular to a bearing sealing retaining ring. Background Technology

[0002] Bearing seals are components used for sealing bearings. Their functions include preventing leakage of lubricating media, blocking external contaminants, and maintaining a stable operating environment for the bearing.

[0003] Bearing seals are mostly made of elastic materials, such as nitrile rubber and silicone rubber. However, existing bearing seals are mostly snapped onto the bearing. Over time, the bearing seals will gradually age, resulting in decreasing connection stability and easy detachment. Therefore, in view of the above situation, there is an urgent need to develop a bearing seal with good sealing performance, high connection stability, and resistance to detachment, in order to overcome the shortcomings in current practical applications and meet current needs. Utility Model Content

[0004] The purpose of this invention is to provide a bearing sealing ring to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A bearing sealing ring includes a circular retaining ring, an exhaust pipe, an outer retaining ring, and an inner retaining ring. The outer retaining ring and the inner retaining ring are fixed on the circular retaining ring. An annular cavity is provided inside the circular retaining ring. Multiple adsorption ports communicating with the annular cavity are provided on the circular retaining ring. An exhaust pipe communicating with the annular cavity is fixed on the circular retaining ring. The outer diameter of the outer retaining ring gradually increases from left to right, and the inner diameter of the inner retaining ring gradually decreases from left to right.

[0007] Preferably, the circular retaining ring, outer retaining ring, and inner retaining ring are all made of rubber.

[0008] Preferably, the vent pipe is detachably connected to a plug via threads.

[0009] Preferably, both the vent pipe and the plug are made of plastic.

[0010] The utility model discloses a beneficial effect is: this bearing seal baffle, when installing, the outer snap ring is gradually inserted to the inside of bearing outer ring, and the outer diameter of outer snap ring is contacted with the inside of bearing outer ring, because the outer ring diameter of outer snap ring gradually increases from left to right, so that the outer snap ring will be contacted with bearing outer ring more and more closely when inserting, similarly, the inner snap ring is gradually inserted to the outside of bearing inner ring, and the inner diameter of inner snap ring is contacted with the outside of bearing inner ring, because the inner ring diameter of inner snap ring gradually reduces from left to right, so that the inner snap ring will be contacted with bearing inner ring more and more closely when inserting, so that the sealing is better, after installing, the ring baffle is attached with bearing, then, the plug is taken down, and the person extrusion annular cavity makes its internal air from the air pipe and is discharged, so that the negative pressure is formed in annular cavity, then, the plug is screwed on and is blocked to the air pipe, because the negative pressure in annular cavity makes the adsorption mouth tightly adsorbed on the ring baffle (similar with the principle of suction cup), so that the stability of ring baffle and bearing connection is improved, and accidental falling is prevented.

[0018] The technical scheme in the embodiments of the utility model will be described clearly and completely below in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0019] The specific embodiments are given below.

[0020] Referring to Figures 1-5 The utility model discloses an embodiment of a bearing sealing baffle, which comprises a circular baffle 1, an air outlet pipe 2, an outer snap ring 3, an inner snap ring 4 and a bearing 5. The outer snap ring 3 and the inner snap ring 4 are fixed to the circular baffle 1. The circular baffle 1, the outer snap ring 3 and the inner snap ring 4 are made of rubber, which has a certain elastic deformation capacity. The outer snap ring 3 and the inner snap ring 4 are used to be clamped to the bearing 5. The circular baffle 1 is provided with an annular cavity 102. The circular baffle 1 is provided with a plurality of suction ports 101 connected to the annular cavity 102. The circular baffle 1 is fixed with the air outlet pipe 2 connected to the annular cavity 102. The air outlet pipe 2 is detachably connected with a plug 201 through threads. The air outlet pipe 2 and the plug 201 are made of plastic. The outer diameter of the outer snap ring 3 gradually increases from left to right. The inner diameter of the inner snap ring 4 gradually decreases from left to right.

[0021] Working principle: when installing the bearing sealing baffle, the outer snap ring 3 is gradually inserted into the inner side of the outer ring of the bearing 5. The outer diameter of the outer snap ring 3 is in contact with the inner side of the outer ring of the bearing 5. Since the outer diameter of the outer snap ring 3 gradually increases from left to right, the outer snap ring 3 will be in contact with the outer ring of the bearing 5 more and more closely when being inserted. Similarly, the inner snap ring 4 is gradually inserted into the outer side of the inner ring of the bearing 5. The inner diameter of the inner snap ring 4 is in contact with the outer side of the inner ring of the bearing 5. Since the inner diameter of the inner snap ring 4 gradually decreases from left to right, the inner snap ring 4 will be in contact with the inner ring of the bearing 5 more and more closely when being inserted, so that the sealing performance is better. After installation, the circular baffle 1 is in contact with the bearing 5. Then, the plug 201 is removed. The air inside the annular cavity 102 is discharged from the air outlet pipe 2 by extruding the annular cavity 102, so that a negative pressure is formed in the annular cavity 102. Then, the plug 201 is screwed to block the air outlet pipe 2. Since the negative pressure in the annular cavity 102 makes the suction ports 101 tightly suck to the circular baffle 1 (similar to the principle of a suction cup), the stability of the connection between the circular baffle 1 and the bearing 5 is improved, and accidental falling is prevented.

[0022] The above is only a preferred embodiment of the utility model, but the protection scope of the utility model is not limited to this. Any skilled person in the art can make equivalent replacement or change according to the technical scheme and the utility model concept of the utility model within the technical range disclosed by the utility model, which should be covered in the protection scope of the utility model.
