[0003] Currently, the rubber vibration dampers used in the industry consist of an upper plate and a lower plate, with damping rubber between them. This type of vibration damper has the following drawbacks in actual use: 1. Due to the large vibrations of the mechanical equipment, the damping effect of this type of damper is poor, and its service life is short, requiring regular replacement, which is time-consuming and labor-intensive; 2. The preload of the rubber components of this damper cannot be adjusted, resulting in poor adaptability, requiring one-to-one customization based on the various parameters of the equipment. This technical problem urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a ring rubber vibration damper, which has a good vibration damping effect, can adapt to multiple application scenarios and load conditions, and has high reliability and durability.

[0008] The second annular rubber component fits against the inner wall of the vibration damping seat and is concentric with the first annular rubber component. The second annular rubber component passes through the connector and a first gasket is installed between the second annular rubber component and the connector.

[0009] A screw is fixedly connected to the outer end of the first annular rubber part and at the top of the connector;

[0010] A rectangular groove in the shape of a cross is provided on the vibration damping seat.

[0011] In a preferred embodiment of this utility model, the vibration damping seat is made of a rigid material.

[0035] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0036] like Figure 1-3 As shown, the present invention provides an annular rubber vibration damper, including a vibration damping seat 1, which is configured as an inverted bowl shape, with a vertical first through hole in the middle, and a connector 2 passing through the first through hole;

[0037] The first annular rubber component 3 is mounted on the vibration damping seat 1 and is coaxial with the first through hole of the vibration damping seat 1, and is sleeved on the connecting component 2;

[0038] The second annular rubber component 4 fits against the inner wall of the vibration damping seat 1 and is concentric with the first annular rubber component 3. The second annular rubber component 4 passes through the connector 2 and a first gasket 5 is installed between it and the connector 2.

[0039] A screw connector 6 is fixedly connected to the outer end of the first annular rubber part 3 and at the top of the connector 2;

[0040] A rectangular groove in the shape of a cross is provided on the vibration damping seat 1;

[0041] The working principle and beneficial effects of the above embodiments are as follows:

[0042] When the screw 6 is screwed, pressure is applied to the first annular rubber part 3. Since the first annular rubber part 3 and the second annular rubber part 4 are concentric and both are sleeved on the connecting part 2, the pressure will be transmitted to the second annular rubber part 4. At the same time, a cross-shaped rectangular groove is opened on the damping seat 1 to balance the pressure borne by the first rubber part 3 and the second rubber part 4.

[0043] The first annular rubber component 3 and the second annular rubber component 4 will undergo elastic deformation after being subjected to pressure. The first annular rubber component 3 and the second annular rubber component 4 are concentric, which makes the force transmission more uniform, thereby absorbing and buffering external forces and playing a vibration reduction role.

[0044] This invention utilizes the elastic properties of rubber. When the connecting part 2 is subjected to axial reciprocating periodic loads, the first annular rubber part 3 and the second annular rubber part 4 cooperate to form a vibration damping seat 1 with a cross-shaped rectangular groove, which can withstand loads in multiple directions. During the buffering process, the external force is transmitted and canceled out between the first annular rubber part 3 and the second annular rubber part 4. At the same time, the degree of deformation of the rubber parts can be changed by adjusting the degree of screwing of the screw 6, adapting to various working conditions, improving the vibration damping effect and the service life of the vibration damper.

[0045] In one embodiment,

[0046] The aforementioned vibration damping seat 1 is made of rigid material, providing a stable support structure that ensures that the geometry and positional relationship of the entire vibration damper remain unchanged during use, thereby guaranteeing the stable performance of the vibration damper.

[0047] In one embodiment, such as Figure 4 As shown,

[0048] The aforementioned vibration damping seat 1 includes a hollow frustum-shaped shell 11, a bowl bottom 12 fitted on the top of the frustum-shaped shell 11, and a bowl wing 13 fitted on the bottom of the frustum-shaped shell 11. A first through hole through which the aforementioned connector 2 passes is provided in the middle of the bowl bottom 12.

[0049] The frustum-shaped housing 11 has a structure that is smaller at the top and larger at the bottom, which can provide good stability and load-bearing capacity. At the same time, it provides sufficient installation space for the internal second annular rubber part 4 and connector 2. The cup wing 13 fits into the bottom of the frustum-shaped housing 11, which plays a supporting and fixing role. Meanwhile, the cup wing 13 can cooperate with other components to further enhance the installation stability of the shock absorber.

[0050] In one embodiment,

[0051] The thickness of the bowl bottom 12 is the same as the thickness of the side wall of the frustum-shaped shell 11, and the cross-shaped rectangular groove is formed on the bowl bottom 12 and extends to the upper end face of the bowl wing 13.

[0052] The thickness of the bowl bottom 12 is the same as the thickness of the side wall of the frustum-shaped shell 11. This design makes the structure of the vibration damping seat 1 more uniform. When subjected to external force, the stress distribution is more uniform, reducing stress concentration points and thus improving the strength and durability of the entire vibration damping seat 1.

[0053] In one embodiment,

[0054] A second through hole for the connector 2 is provided in the middle of the first annular rubber part 3 and the second annular rubber part 4, and the gap between the second through hole and the connector 2 is 0.05-0.1mm.

[0055] The small gap allows the connector 2 to have a certain degree of freedom of movement within the second through hole of the rubber part, thereby better dispersing and absorbing vibration energy. If the gap is too large, the connector 2 may slide excessively within the rubber part, leading to accelerated wear of the rubber part. If the gap is too small, it may cause excessive friction between the rubber part and the connector 2, or even jamming. A gap design of 0.05-0.1mm can effectively reduce wear and extend the service life of the shock absorber.

[0056] In one embodiment,

[0057] Multiple through holes for bolts are evenly distributed on the aforementioned bowl wing 13 for connecting and fixing to external equipment. The through holes are staggered from the rectangular groove in the circumferential direction to improve the structural strength of the vibration damping seat 1.

[0058] In one embodiment,

[0059] The width of the rectangular groove is set between 5 and 7 mm. An appropriate groove width can ensure that the vibration damping seat 1 still maintains sufficient strength when subjected to external forces.

[0060] In one embodiment,

[0061] The aforementioned connector 2 is configured as a connecting bolt, one end of which is a bolt head and the other end is a threaded end with external threads. Between the bolt head and the threaded end is a smooth rod. The vibration damping seat 1, the first annular rubber component 3, and the second annular rubber component 4 are sleeved on the smooth rod of the connecting bolt.

[0062] The vibration damping seat 1, the first annular rubber component 3, and the second annular rubber component 4 are all fitted onto the smooth rod portion of the connecting bolt. The smooth surface of the smooth rod allows the rubber components to slide freely on it, thereby achieving elastic deformation during the vibration damping process.

[0063] In one embodiment,

[0064] The aforementioned screw connector 6 is configured as a nut, and a second washer 7 is installed between the nut and the first annular rubber component 3. The second washer 7 can disperse the pressure applied by the nut and protect the surface of the rubber component.

[0065] In summary:

[0066] This utility model discloses a ring rubber vibration damper. Utilizing the elastic properties of rubber, when the connecting parts are subjected to axial reciprocating periodic loads, the first and second ring rubber parts cooperate to form a vibration damping seat with a cross-shaped rectangular groove, which can withstand loads in multiple directions. During the buffering process, the external force is transmitted and canceled out between the first and second ring rubber parts, thereby improving the vibration damping effect and the service life of the vibration damper.

[0067] By tightening the screws, the preload of the rubber parts can be adjusted, thereby changing the stiffness and damping characteristics of the shock absorber to adapt to different usage scenarios and load conditions.

[0068] This utility model designs a rigid vibration damping seat to provide stable support. The thickness of the bowl bottom and the frustum-shaped shell is consistent, and it fits well with the smooth rod part of the connecting piece to ensure that the stress is evenly distributed on the vibration damping seat and reduce stress concentration points.

[0069] This utility model discloses a ring-shaped rubber vibration damper, which has high vibration damping effect, structural stability, reliability and durability, and is easy to install and maintain.
