Description

Technical Field

[0001] The utility model relates to the field of vibration isolator accessories, and particularly relates to a rubber spring for a rubber spring vibration isolator. Background Art

[0002] With the continuous development of urban rail transit, the resulting vibration and noise are inevitable. In order to reduce the impact of the vibration and noise generated by rail transit on people's lives, the spring floating slab track bed came into being. During use, steel springs have problems such as rust, and the stiffness of steel springs needs to be adjusted by adjusting parameters such as the wire diameter, outer diameter, and height of the steel springs.

[0003] The prior art has the following defects: (1) Corrosion problem: Steel springs are easily affected by environmental factors during use, especially in humid environments or environments containing corrosive chemical substances, and are prone to rust. Rust not only reduces the performance of the spring but also shortens its service life. (2) Complex stiffness adjustment: The stiffness of steel springs is usually determined by parameters such as their wire diameter, outer diameter, and height. Therefore, in order to achieve the required vibration isolation effect, it is necessary to accurately calculate and manufacture steel springs of specific specifications, which increases the complexity of design and production. (3) High maintenance cost: Once a steel spring is damaged or its performance deteriorates, the entire spring usually needs to be replaced, which not only increases the maintenance cost but also requires professional equipment and technicians for replacement, increasing the difficulty and time of maintenance. (4) Stability limitation: The vertical and horizontal stability of steel springs is limited by their materials and structures, and may not provide sufficient stability under certain extreme working conditions, affecting the vibration isolation effect. To overcome the above defects, it is necessary to develop a new spring structure suitable for vibration isolators. Summary of the Utility Model

[0004] In order to solve the above problems, the embodiment of the utility model provides a rubber spring for a rubber spring vibration isolator. Compared with the original steel spring, the rubber spring can improve the vertical and horizontal stability of the rubber spring vibration isolator, and the modular design can reduce the maintenance cost of the rubber spring vibration isolator.

[0005] In order to achieve the above-mentioned purpose, the embodiment of the utility model specifically adopts the following technical solutions: a rubber spring for a rubber spring isolator, comprising a rubber spring body, the rubber spring body is conical, the rubber spring body comprises a rubber split component, the rubber split component is a fan-shaped arc structure, a plurality of rubber split components form a conical support body, the rubber split components are independent of each other and can be replaced individually, and a limiting boss that cooperates with the limiting groove of the base of the rubber spring isolator is provided on the inner wall of the rubber split component; the limiting boss structural design can enhance the lateral and vertical stability of the rubber spring isolator. The split structural design of the rubber split component allows the rubber spring split structure to be replaced after the rubber spring isolator fails, without the need to replace the entire rubber spring structure, thereby reducing operating and maintenance costs and reducing the waste of maintenance resources.

[0006] In order to further optimize the utility model, the following technical solutions can be preferably used:

[0007] Preferably, the rubber split component comprises a rubber body, an outer skeleton is arranged at the inner and outer sides of the rubber body, and an inner skeleton is arranged at the inner side of the rubber body.

[0008] Preferably, the inner and outer skeletons are metal bodies, which can improve the lateral stiffness of the rubber spring vibration isolator and increase the lateral stability of the rubber spring vibration isolator.

[0009] Preferably, the inner frame, the outer frame and the rubber body are vulcanized and bonded into one body.

[0010] Preferably, the inner and outer metal skeletons are both hollow structures, which can increase the contact area between the rubber and the inner and outer skeletons, and can improve the bonding stability between the rubber and the inner and outer skeletons.

[0011] Preferably, the limiting boss is arranged on the inner frame and protrudes from the inner side surface of the rubber body.

[0012] Preferably, the cross-section of the limiting boss is a polygonal structure.

[0013] The beneficial effects of the above technical solution are as follows:

[0014] 1) Enhanced stability and rigidity: By setting a metal outer frame on the outside of the rubber body and a metal inner frame on the inside, the overall lateral rigidity of the rubber spring isolator can be significantly improved. This structural design makes the rubber spring more stable when subjected to lateral loads, reduces the risk of deformation under high-intensity working conditions, and extends the service life of the product.

[0015] 2) Improve bonding stability: The inner and outer metal frames are combined with the rubber body through the vulcanization bonding process, ensuring that the connection between the rubber body and the metal frame has extremely high stability and durability. The vulcanization bonding process provides strong bonding force, preventing the separation between the rubber and the metal frame during use, and ensuring the reliability of the product.

[0016] 3) Increased contact area: The hollow metal skeleton not only reduces the overall weight, but also increases the contact area between the rubber and the metal skeleton. This structure makes the bonding surface larger, further improves the stability and uniformity of the bonding, helps to disperse stress, and reduces the potential risk of damage caused by stress concentration.

[0017] 4) Improve installation efficiency and maintenance convenience: The design of the limit boss, especially its polygonal cross-section, can more accurately match the limit slot on the base of the rubber spring isolator, improving the accuracy and efficiency of installation. At the same time, the design also takes into account the convenience of maintenance. When a damaged rubber split component needs to be replaced, it can be quickly located and replaced without replacing the entire rubber spring, greatly reducing maintenance costs and time.

[0018] 5) Optimize vibration isolation performance: By adopting a conical support body and a rubber split component with a fan-shaped arc structure, the rubber spring vibration isolator of the utility model can provide a more excellent vibration isolation effect. The conical structure is conducive to dispersing vibration and pressure from different directions, while the fan-shaped arc design further improves the vertical and lateral stability of the spring, allowing the vibration isolator to adapt to more complex working conditions.

[0019] 6) Reduced operation and maintenance costs: Since the rubber split parts are independent of each other and can be replaced individually, this design greatly reduces the operation and maintenance costs of the rubber spring isolator. When part of the rubber split parts is damaged or the performance is degraded, there is no need to replace the entire rubber spring structure, only the damaged split parts need to be replaced, which reduces resource waste and achieves an economical and efficient maintenance strategy.

[0020] In summary, the implementation of these technical solutions not only improves the performance and reliability of rubber spring isolators, but also reduces their maintenance costs, improves economic benefits, and makes their application in rail transit and other fields more extensive and efficient.

[0028] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0029] Example 1: Figures 1-3 As shown, a rubber spring for a rubber spring isolator includes a rubber spring body 1, which is conical, wherein the top and bottom of the rubber spring body are designed with arc-shaped inclined grooves; the rubber spring body includes a rubber split component 2, which is a fan-shaped arc structure, and a plurality of rubber split components form a conical support body. Since the rubber split components are independent of each other, they can be replaced individually. This design greatly reduces the operation and maintenance costs of the rubber spring isolator. When part of the rubber split components is damaged or the performance is degraded, there is no need to replace the entire rubber spring structure, only the damaged split components need to be replaced in a targeted manner, which reduces resource waste and realizes an economical and efficient maintenance strategy. A limiting boss 3 that cooperates with the limiting groove of the base of the rubber spring isolator is installed on the inner wall of the rubber split component, wherein the structural design of the limiting boss 3 can enhance the lateral and vertical stability of the rubber spring isolator. The split structure design of the rubber split parts allows the rubber spring split structure to be replaced after the rubber spring isolator fails, without replacing the entire rubber spring structure, which reduces the operating and maintenance costs and reduces the waste of maintenance resources; by adopting the rubber split parts with conical support bodies and fan-shaped arc structures, the rubber spring isolator of the utility model can provide a more excellent vibration isolation effect. The conical structure is conducive to dispersing vibration and pressure from different directions, while the fan-shaped arc design further improves the vertical and lateral stability of the spring, allowing the isolator to adapt to more complex working conditions.

[0030] Among them, the rubber split component 2 includes a rubber body 4. An outer skeleton 5 is installed at the inner and outer positions of the rubber body, and an inner skeleton 6 is installed at the inner position of the rubber body. The inner and outer skeletons are metal bodies, which can improve the lateral stiffness of the rubber elastic vibration isolator and increase the lateral stability of the rubber spring vibration isolator. Further, the inner skeleton 6, the outer skeleton 5 and the rubber body are vulcanized and bonded into one body, and the inner and outer metal skeletons and the rubber body are combined through the vulcanization bonding process, ensuring that the connection between the rubber body and the metal skeleton has extremely high stability and durability. The vulcanization bonding process provides strong adhesion, preventing the separation between the rubber and the metal skeleton during use and ensuring the reliability of the product.

[0031] In addition, in an optional design, both the inner and outer metal skeletons are of a hollow structure. The hollow-structured metal skeletons not only reduce the overall weight but also increase the contact area between the rubber and the metal skeletons. This structure results in a larger bonding surface, further improving the bonding stability and uniformity, helping to disperse stress and reducing the potential damage risk caused by stress concentration.

[0032] Among them, the limiting boss 3 is installed on the inner skeleton 6 and protrudes from the inner side surface of the rubber body 4, that is, the limiting boss is integrally designed with the inner skeleton to ensure the strength of the overall structure.

[0033] Embodiment 2: As Figures 4-6 shown, on the premise of ensuring the structural strength of the limiting boss, the cross-section of the limiting boss 3 is a polygonal structure, which can be more accurately matched with the limiting groove on the base of the rubber spring vibration isolator, improving the installation accuracy and efficiency. In this embodiment, only the triangular structure protrusion is taken as an example in the attached drawing, and other forms of polygonal structures are also included.

Therefore, it should not be construed as a limitation to the present utility model. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0035] In addition, it should be noted that in the description of the present utility model, unless otherwise clearly specified and defined, the terms "installed", "connected", and "coupled" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0037] So far, the technical solution of the present utility model has been described in conjunction with the preferred embodiments shown in the drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present utility model is obviously not limited to these specific embodiments.
