Abstract
Description
Technical Field
[0001] This utility model relates to the field of bearings, and in particular to a high-performance bearing ring. Background Technology
[0002] 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.
[0003] Most existing engine tensioner bearings are embedded inside the tensioner, which requires a lot of time for maintenance and replacement, making them very inconvenient.
[0004] Therefore, it is necessary to provide a new high-performance bearing ring to solve the above-mentioned technical problems. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides a high-performance bearing ring, which solves the problem that the maintenance and replacement of existing engine tensioner bearings require a lot of time from the staff, which is very inconvenient.
[0006] The high-performance bearing ring provided by this utility model includes a mounting post fixed on the engine housing, an outer ring, an inner ring, and a number of balls. The mounting post has a threaded hole and a stop is fixed on the mounting post.
[0007] A tensioning wheel is provided on one side of the engine housing. Several limiting grooves are opened inside the tensioning wheel. Several limiting blocks are fixed on the outer surface of the outer ring. The limiting blocks are slidably connected to the limiting grooves.
[0008] In a preferred embodiment, a positioning bolt is provided on one side of the tensioning wheel, a pressure plate is fixed on the positioning bolt, and the threaded end of the positioning bolt passes through the inner ring and is screwed into the threaded hole.
[0009] The pressure plate is in contact with the inner ring.
[0010] In a preferred embodiment, the stop is in contact with the inner ring, but not with the outer ring.
[0011] In a preferred embodiment, the pressure plate does not contact the outer ring, and a rubber protective pad is provided on the side of the pressure plate that contacts the inner ring.
[0012] In a preferred embodiment, the positioning bolt has multiple through holes, the inner ring has multiple threaded grooves on one side, and the pressure plate has a self-locking bolt on one side, the threaded end of the self-locking bolt passing through the through holes and extending into the threaded grooves.
[0013] In a preferred embodiment, the self-locking bolt has the opposite thread direction to the positioning bolt.
[0014] The beneficial effects of this utility model are as follows: When installing this bearing ring, the operator only needs to insert the limiting block on the outer ring into the limiting groove on the tensioning wheel, then place the inner ring on the mounting post so that the inner ring contacts the stop seat, and finally tighten the positioning bolt to fix the bearing ring and the tensioning wheel.
[0015] When it is necessary to disassemble this bearing, simply unscrew the positioning bolts and pull the bearing out from the tensioner wheel to carry out subsequent maintenance and replacement operations. The operation is simple and convenient, saving workers a lot of maintenance time.
[0016] The stability of the bearing ring can be increased by setting a self-locking bolt. Since the threads of the self-locking bolt and the positioning bolt are opposite, it can have a loosening effect in actual use. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0022] Please refer to the following: Figure 1 , Figure 2 as well as Figure 3 ,in Figure 1 The main structural perspective view of the high-performance bearing ring provided by this utility model Figure 1 ; Figure 2 The main structural perspective view of the high-performance bearing ring provided by this utility model Figure 2 ; Figure 3 A structural view of the positioning bolt provided by this utility model.
[0023] In the specific implementation process, such as Figures 1-3 As shown, the bearing includes a mounting post 2 fixed on the engine housing 1, an outer ring 7, an inner ring 12, and several balls 13. The outer ring 7, the inner ring 12, and the balls 13 constitute a whole bearing. The mounting post 2 has a threaded hole 3 and a stop 4 is fixed on the mounting post 2. The stop 4 is in contact with the inner ring 12 and is not in contact with the outer ring 7. When installing the tension wheel 5, the inner ring 12 can be placed on the mounting post 2 so that the inner ring 12 is in contact with the stop 4.
[0024] A tensioning wheel 5 is provided on one side of the engine housing 1. Several limiting grooves 6 are provided inside the tensioning wheel 5. Several limiting blocks 8 are fixed on the outer surface of the outer ring 7. The limiting blocks 8 are slidably connected to the limiting grooves 6.
[0025] A positioning bolt 9 is provided on one side of the tensioning wheel 5. A pressure plate 10 is fixed on the positioning bolt 9. The threaded end of the positioning bolt 9 passes through the inner ring 12 and is screwed into the threaded hole 3. The pressure plate 10 is in contact with the inner ring 12, but not with the outer ring 7. A rubber protective pad is provided on the side of the pressure plate 10 that is in contact with the inner ring 12 to protect the surface of the bearing inner ring 12.
[0026] The positioning bolt 9 has multiple through holes 11, and the inner ring 12 has multiple threaded grooves 14 on one side. The pressure plate 10 has a self-locking bolt 15 on one side. The threaded end of the self-locking bolt 15 passes through the through hole 11 and extends into the threaded groove 14. The thread direction of the self-locking bolt 15 is opposite to that of the positioning bolt 9. By setting the self-locking bolt 15, the stability of the bearing ring during use can be increased. Since the thread direction of the self-locking bolt 15 is opposite to that of the positioning bolt 9, it can play a loosening role in actual use.
[0027] The working principle of this utility model is as follows: When installing the bearing ring, the operator only needs to insert the limiting block 8 on the outer ring 7 into the limiting groove 6 on the tension wheel 5, and then place the inner ring 12 on the mounting post 2 so that the inner ring 12 contacts the stop seat 4. Finally, tighten the positioning bolt 9 to fix the bearing ring and the tension wheel 5. When it is necessary to disassemble the bearing, first unscrew the positioning bolt 9, and then pull the bearing out from the tension wheel 5 to carry out subsequent maintenance and replacement operations.
[0028] The stability of the bearing ring can be increased by setting the self-locking bolt 15. Since the self-locking bolt 15 and the positioning bolt 9 have opposite thread directions, it can have a loosening effect in actual use.
[0029] 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.
