Description

Technical Field

[0001] This utility model relates to the field of bearings, and in particular to a high-load bearing ring. Background Technology

[0002] The car engine is the power source for a car; it's the heart of the vehicle and determines its power, fuel economy, stability, and environmental performance. The car engine provides power by converting other forms of energy into mechanical energy.

[0003] An engine tensioner is a device used to maintain proper belt tension, ensuring close contact between the belt and pulleys and preventing slippage, detachment, or excessive wear. It typically consists of a pulley body, bearings, and an adjusting mechanism.

[0004] Most existing engine tensioner bearing rings are directly embedded inside the tensioner, which requires a lot of time for maintenance and replacement, making it very inconvenient.

[0005] Therefore, it is necessary to provide a new high-load bearing ring to solve the above-mentioned technical problems. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a high-load bearing ring, which solves the problem that most existing engine tensioner bearing rings are directly embedded inside the tensioner, which requires a lot of time for workers to carry out maintenance and replacement, and is very inconvenient.

[0007] The high-load bearing ring provided by this utility model includes a tensioning wheel, an outer bearing ring, and an inner bearing ring. A plurality of balls are arranged between the outer bearing ring and the inner bearing ring. A first stop is fixed at the inner ring of the tensioning wheel, and a plurality of first threaded grooves are opened on one side of the tensioning wheel.

[0008] A connecting ring plate is fixed on the outer ring of the bearing. A number of high-strength screws are provided on one side of the connecting ring plate. The threaded end of the high-strength screws passes through the connecting ring plate and is screwed into the first threaded groove.

[0009] In a preferred embodiment, the high-strength screw is galvanized.

[0010] In a preferred embodiment, it further includes a mounting post fixed to the engine, the mounting post having a second threaded groove and a second stop mounted on the mounting post;

[0011] A final assembly screw is provided on one side of the inner ring of the bearing. The threaded end of the final assembly screw passes through the inner ring of the bearing and is screwed into the second thread groove.

[0012] In a preferred embodiment, a metal dustproof ring is provided on the side of the outer ring of the bearing away from the assembly screw, and an outer dustproof plate is fixed on the assembly screw.

[0013] In a preferred embodiment, the diameter of the outer dustproof plate is smaller than the inner diameter of the outer ring of the bearing.

[0014] The beneficial effects of this utility model are:

[0015] When using this bearing ring, the operator only needs to place the outer ring of the bearing into the inner ring of the tensioning wheel, so that one side of the outer ring of the bearing contacts the first stop. Finally, the connecting ring plate and the tensioning wheel are fixed together with high-strength screws to complete the bearing installation. The operation is simple and convenient.

[0016] When it is necessary to install this tensioner, after the bearing inner ring is put on the mounting post and in contact with the second stop, the operator only needs to screw the threaded end of the assembly screw through the bearing inner ring into the second thread groove to complete the fixing of the tensioner.

[0017] Metal dustproof rings and outer dustproof plates can prevent external dust from entering the bearing, thus improving the bearing's service life. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please refer to the following: Figure 1 , Figure 2 as well as Figure 3 ,in Figure 1 A perspective view of the main structure of the high-load bearing ring provided by this utility model; Figure 2Main structural plan view of the high-load bearing ring provided by this utility model Figure 1 ; Figure 3 Main structural plan view of the high-load bearing ring provided by this utility model Figure 2 .

[0024] In the specific implementation process, such as Figures 1-3 As shown, the bearing includes a tensioning wheel 1, an outer bearing ring 2, and an inner bearing ring 3. Several balls 4 are arranged between the outer bearing ring 2 and the inner bearing ring 3. A first stop 5 is fixed at the inner ring of the tensioning wheel 1. Several first threaded grooves 6 are opened on one side of the tensioning wheel 1. A connecting ring plate 7 is fixed on the outer bearing ring 2. Several high-strength screws 8 are arranged on one side of the connecting ring plate 7. The threaded end of the high-strength screws 8 passes through the connecting ring plate 7 and is screwed into the first threaded groove 6. The high-strength screws 8 are galvanized to improve their service life. When using this bearing ring, the operator only needs to place the outer bearing ring 2 into the inner ring of the tensioning wheel 1 so that one side of the outer bearing ring 2 contacts the first stop 5. Finally, the connecting ring plate 7 and the tensioning wheel 1 are fixed together by the high-strength screws 8 to complete the bearing installation. The operation is simple and convenient.

[0025] It also includes a mounting post 9 fixed to the engine, a second threaded groove 10 on the mounting post 9, a second stop 11 installed on the mounting post 9, and a general assembly screw 12 on one side of the bearing inner ring 3. The threaded end of the general assembly screw 12 passes through the bearing inner ring 3 and is screwed into the second threaded groove 10. When it is necessary to install this tensioning wheel 1, after the bearing inner ring 2 is put on the mounting post 9 and in contact with the second stop 11, the operator only needs to screw the threaded end of the general assembly screw 12 through the bearing inner ring 3 and into the second threaded groove 10 to complete the fixing of the tensioning wheel 1.

[0026] A metal dustproof ring 13 is provided on the side of the bearing outer ring 2 away from the assembly screw 12. An outer dustproof plate 14 is fixed on the assembly screw 12. The diameter of the outer dustproof plate 14 is smaller than the inner diameter of the bearing outer ring 2, so it does not affect the rotation of the bearing outer ring 2. The metal dustproof ring 13 and the outer dustproof plate 14 can prevent external dust from entering the bearing.

[0027] The working principle of this utility model is as follows: When using this bearing ring, the operator only needs to put the outer ring 2 of the bearing into the inner ring of the tensioning wheel 1 so that one side of the outer ring 2 of the bearing contacts the first stop 5. Finally, the connecting ring plate 7 and the tensioning wheel 1 are fixed together by the high-strength screws 8 to complete the installation of the bearing. The operation is simple and convenient.

[0028] When it is necessary to install this tensioning wheel 1, after the bearing inner ring 2 is put on the mounting post 9 and comes into contact with the second stop 11, the operator only needs to screw the threaded end of the assembly screw 12 through the bearing inner ring 3 into the second threaded groove 10 to complete the fixing of the tensioning wheel 1.

[0029] The metal dustproof ring 13 and the outer dustproof plate 14 can prevent external dust from entering the bearing.

[0030] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
