[0024] 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.

[0025] Please see Figures 1-5 This utility model provides a damping bearing technical solution.

[0026] A damping bearing, comprising:

[0027] Inner ring 1, the outer wall of inner ring 1 is provided with inner ring groove 2 and damping ring groove 3;

[0028] Outer ring 4 is fitted outside the inner ring 1. The inner wall of the outer ring 4 is provided with an outer ring groove 5. A rotating cavity 6 is formed between the outer ring groove 5 and the inner ring groove 2.

[0029] Rotating component 7 is installed inside the rotating cavity 6, and the outer ring 4 and the inner ring 1 can rotate through the rotating component 7;

[0030] Damping ring 8 is installed in damping ring groove 3. The outer wall of damping ring 8 abuts against the inner wall of outer ring 4, and the inner wall of damping ring 8 abuts against the bottom surface of damping ring groove 3. Damping ring 8 is in a compressed state.

[0031] Because the outer wall of the damping ring 8 abuts against the inner wall of the outer ring 4, and the inner wall of the damping ring 8 abuts against the bottom surface of the damping ring groove 3, the damping ring 8 is in a compressed state, which enables damping when the outer ring 4 rotates relative to the inner ring 1. Compared with the existing spring method of generating damping, the method of using the damping ring 8 is more convenient to install, simpler to process, and lower in cost. The integral damping ring 8 achieves uniform pressure distribution.

[0032] like Figure 4 As shown, the damping ring 8 includes an O-ring 9 and a rectangular ring 10. The O-ring 9 is an annular elastic element with a circular cross-section, and the rectangular ring 10 is an annular polytetrafluoroethylene element with a rectangular cross-section. The rectangular ring 10 is fixed to the outside of the O-ring 9. The outer wall of the O-ring 9 abuts against the bottom surface of the damping ring groove 3, and the side of the rectangular ring 10 away from the O-ring 9 abuts against the inner wall of the outer ring 4. Its planar structure forms a surface contact with the inner wall of the outer ring 4 under compression, which enhances the support stability.

[0033] like Figure 4 As shown, the damping bearing also includes a sealing ring 11, which is an annular elastic sealing component. The inner wall of the outer ring 4 is provided with a sealing groove 13. The outer end of the sealing ring 11 is inserted into the sealing groove 13. The inner wall of the sealing ring 11 abuts against the outer wall of the inner ring 1. The rotating component 7 is located between the sealing ring 11 and the damping ring 8.

[0034] The sealing ring 11 and damping ring 8 serve a sealing function, preventing the intrusion of external contaminants. The sealing groove 13 refers to an annular groove located on the inner wall of the outer ring 4, which can be machined to fit the outer end of the sealing ring 11. It restricts the axial displacement of the sealing ring 11 through an insertion method, ensuring the installation stability of the sealing ring 11. The rotating component 7 located between the sealing ring 11 and the damping ring 8 means that the ball or roller is confined within the closed cavity formed by the sealing ring 11 and the damping ring 8. This arrangement isolates the rotating area from the outside environment, preventing contaminants from entering the rotating cavity 6 and interfering with bearing operation.

[0035] like Figure 4As shown, the openings of the inner groove 2 and the outer groove 5 are arranged opposite to each other. The rotating component 7 is configured as several rolling balls, which are installed between the inner groove 2 and the outer groove 5. The rolling balls are constrained in the rotating cavity 6 formed by the arc-shaped walls of the two, and the load is evenly distributed on the multiple rolling balls.

[0036] like Figure 4 As shown, two grooves 12 are provided on the outer wall of the rectangular ring 10.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
