It should be understood that the specific embodiments described herein are part of the embodiments of the present utility model, rather than all of them, and are only used to explain the embodiments of the present utility model, not to limit the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0023] Embodiment 1

[0024] Please refer to Figures 1 - 3 , the present utility model provides a technical solution: a highly wear-resistant shock-absorbing bushing, including a bushing body 1. A first assembly strip 4 is inserted into the outer ring surface of the bushing body 1, and a second assembly strip 5 is inserted into the inner ring surface of the bushing body 1. Both the first assembly strip 4 and the second assembly strip 5 are fixed on the surface of an installation ring 6. The installation ring 6 is installed at one end of the bushing body 1. A first rubber strip 11 is provided on the side of the first assembly strip 4 away from the bushing body 1, and a second rubber strip 13 is provided on the side of the second assembly strip 5 away from the inner ring surface of the bushing body 1.

[0025] Embodiment 2

[0026] Referring to the attached Figures 4 to 7 As shown, on the basis of Embodiment 1, in order to install the first assembly strip 4 and the second assembly strip 5 on the bushing body 1, a first assembly groove 2 is opened on the outer ring surface of the bushing body 1. There are multiple first assembly grooves 2, and the multiple first assembly grooves 2 are distributed around the bushing body 1 as the central axis. The second assembly groove 3 corresponds to the first assembly groove 2 one by one. The first assembly groove 2 is in the shape of an arc-shaped plate, and the first assembly groove 2 is inserted into the second assembly groove 3. The outer diameter of the first assembly groove 2 is equal to the outer diameter of the tube body of the bushing body 1. A second assembly groove 3 is opened on the inner ring surface of the bushing body 1. There are multiple second assembly grooves 3, and the multiple second assembly grooves 3 are arranged equidistantly and equally sized along the inner ring surface of the bushing body 1. The second assembly strip 5 corresponds to the second assembly groove 3 one by one, and the second assembly strip 5 is inserted into the second assembly groove 3. And the second assembly strip 5 is in the shape of an arc-shaped plate, and the inner ring diameter of the second assembly strip 5 is equal to the inner ring diameter of the bushing body 1. The installation ring 6 is in the shape of an annular plate structure. The inner ring diameter of the installation ring 6 is greater than the inner ring diameter of the bushing body 1, and the outer ring diameter of the installation ring 6 is less than the outer ring diameter of the tube body of the bushing body 1. Through holes 7 are opened on the surface of the installation ring 6. There are multiple through holes 7, and screws 9 are inserted into the through holes 7. After passing through the through holes 7, the screws 9 are screwed into screw grooves 8, and the screw grooves 8 are opened at the end of the bushing body 1.

[0027] Insert the first assembly strip 4 and the second assembly strip 5 into the corresponding first assembly groove 2 and the second assembly groove 3 respectively. Push the mounting ring 6 towards the bushing body 1 until the mounting ring 6 abuts against one end of the bushing body 1. Then, screw the screw 9 through the through hole 7 and thread it into the threaded groove 8 to complete the fixation of the first assembly strip 4, the second assembly strip 5 and the mounting ring 6 on the bushing body 1. After installation, the first assembly strip 4 and the second assembly strip 5 do not affect the insertion of the bushing body 1 into the inner ring of the bearing, and the shaft body can be inserted into the bushing body 1.

[0028] Embodiment 3

[0029] On the basis of Embodiment 2, in order to provide shock-absorbing structures on both the inner ring side and the outer ring side of the bushing body 1, an embedding groove 10 is formed on the outer ring surface of the first assembly strip 4, and a first rubber strip 11 is fixed inside the embedding groove 10. The thickness of the first rubber strip 11 is greater than the depth of the embedding groove 10. An embedding groove 12 is formed on the inner ring surface of the second assembly strip 5, and a second rubber strip 13 is fixed on the surface of the embedding groove 12. The thickness of the second rubber strip 13 is greater than the depth of the embedding groove 12.

[0030] The reason for adding the first rubber strip 11 to the outer ring surface of the first assembly strip 4 is that after the bushing body 1 is inserted into the inner ring of the bearing, the first rubber strip 11 is deformed by being squeezed between the bushing body 1 and the inner ring of the bearing. The first rubber strip 11 not only constitutes the shock-absorbing structure between the bearing and the bushing body 1, but also increases the friction between the bushing body 1 and the inner ring of the bearing. When the shaft body drives the bushing body 1 to rotate, the bushing body 1 drives the inner ring of the bearing to rotate, thus avoiding wear between the shaft body and the bearing.

[0031] The reason for adding the second rubber strip 13 to the inner ring surface of the bushing body 1 is that after the shaft body is inserted into the bushing body 1, the second rubber strip 13 is clamped between the bushing body 1 and the shaft body, playing a shock-absorbing role and reducing the wear between the bushing body 1 and the shaft body at the same time.

[0032] During use, insert the first assembly strip 4 and the second assembly strip 5 into the corresponding first assembly groove 2 and the second assembly groove 3 respectively. Push the mounting ring 6 towards the bushing body 1 until the mounting ring 6 abuts against one end of the bushing body 1. Then, pass the screw 9 through the through hole 7 and thread it into the threaded groove 8 to complete the fixation of the first assembly strip 4, the second assembly strip 5, and the mounting ring 6 on the bushing body 1. After installation, the first assembly strip 4 and the second assembly strip 5 do not affect the insertion of the bushing body 1 into the inner ring of the bearing, and it meets the requirement that the shaft body is inserted into the bushing body 1. A first rubber strip 11 is installed on the outer ring surface of the first assembly strip 4 so that after the bushing body 1 is inserted into the inner ring of the bearing, the first rubber strip 11 is deformed by being squeezed between the bushing body 1 and the inner ring of the bearing. The first rubber strip 11 not only constitutes a shock-absorbing structure between the bearing and the bushing body 1, but also increases the friction between the bushing body 1 and the inner ring of the bearing. When the shaft body drives the bushing body 1 to rotate, the bushing body 1 drives the inner ring of the bearing to rotate, thereby avoiding wear between the shaft body and the bearing. A second rubber strip 13 is installed on the inner ring surface of the bushing body 1 so that after the shaft body is inserted into the bushing body 1, the second rubber strip 13 is clamped between the bushing body 1 and the shaft body to play a shock-absorbing role and at the same time reduce the wear between the bushing body 1 and the shaft body.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
