Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rubber pads, in particular to a pressure-bearing rubber pad with super wear resistance. Background Art
[0002] With the continuous development of industry, the performance requirements for various rubber pads are getting higher and higher. In many application scenarios, rubber pads need to have both super wear resistance and good pressure bearing capacity.
[0003] Traditional rubber pads often have limitations in terms of wear resistance and pressure bearing capacity. On the one hand, ordinary rubber pads are prone to wear due to friction over long-term use, resulting in a shortened service life. Wear issues are particularly prominent in high-friction, high-pressure environments, such as those in heavy machinery and rail transit. On the other hand, while some rubber pads have some performance in terms of pressure bearing capacity, their wear resistance is unsatisfactory and cannot meet the needs of practical applications.
[0004] To solve these problems, it is crucial to develop a super wear-resistant pressure-bearing rubber pad. This new type of rubber pad needs to be innovative in structure and material to improve its wear resistance and pressure-bearing capacity to meet the requirements of different fields.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0023] Example
[0024] like Figure 1-3 As shown, an embodiment of the present invention provides a super wear-resistant pressure-bearing rubber pad, comprising a body 1;
[0025] The main body 1 is composed of a middle ring 2 and an edge ring 3. The overall structural design is reasonable. The middle ring 2 and the edge ring 3 work together to enable the rubber pad to withstand pressure and perform corresponding functions in different areas. For example, the edge ring 3 mainly deals with friction and wear, while the middle ring 2 focuses on pressure bearing and buffering.
[0026] The middle ring 2 is cylindrical and consists of a buffer middle layer 6 and a pressure-bearing bottom layer 7.
[0027] The cylindrical structure can evenly distribute pressure when under pressure, avoiding stress concentration. It serves as the main pressure-bearing and buffering area. The buffering middle layer 6 can effectively absorb pressure shocks, while the pressure-bearing bottom layer 7 provides stable support.
[0028] The edge ring 3 has a cylindrical shape with a curved cross section and is composed of a wear-resistant surface layer 5 .
[0029] The curved profile design helps reduce stress concentration when in contact with the outside world and improves edge wear resistance. Its main function is to directly withstand friction, protect the internal structure, ensure that the edge of the rubber pad is not easily damaged by wear during use, and extend the overall service life of the rubber pad.
[0030] The hollow holes 4 are arranged in a matrix on the edge ring 3 , and are of equal size but with increasing depth from the edge to the middle.
[0031] The presence of the hollow holes 4 reduces the overall weight of the rubber pad while providing space for deformation when the edge ring 3 is compressed, allowing the rubber pad to better adapt to varying pressure distributions. The gradual depth variation may be intended to further optimize performance based on the differences in pressure and friction at different locations on the edge ring 3. For example, at the edges, where pressure and friction are relatively low, the shallower hollow holes 4 maintain a certain degree of structural strength, while in the middle, where pressure and friction are higher, the deeper hollow holes 4 provide greater room for deformation.
[0032] The wear-resistant surface layer 5 is made of a nitrile rubber layer and constitutes the edge ring 3.
[0033] Nitrile rubber has good wear resistance and can effectively resist external friction, protecting the internal buffer middle layer 6 and the pressure-bearing bottom layer 7, ensuring that the rubber pad can be used for a long time in a high-friction environment without being excessively worn.
[0034] The buffering middle layer 6 can be made of natural rubber or butadiene rubber structural layer, and is provided with vertical reinforcement 8 inside. The shape of the vertical reinforcement 8 is “I”-shaped, and together with the pressure-bearing bottom layer 7, it forms the middle ring 2.
[0035] Natural rubber or butadiene rubber has excellent elasticity, effectively buffering pressure from above and reducing the direct impact of pressure on the underlying pressure-bearing base layer 7. The "I"-shaped vertical reinforcement 8 enhances the structural strength of the buffering middle layer 6, making it less susceptible to deformation under pressure. It also provides support when the rubber pad is subjected to lateral forces, ensuring the stability of the entire rubber pad structure.
[0036] The pressure-bearing bottom layer 7 uses glass fiber or aramid fiber as the filling layer 9, and together with the buffer middle layer 6 forms the middle ring 2.
[0037] Glass fiber or aramid fiber has high strength and can significantly improve the pressure-bearing capacity of the pressure-bearing bottom layer 7 when filled, allowing the rubber pad to withstand greater pressure without cracking or excessive deformation. Together with the buffering middle layer 6, it provides stable support and cushioning performance for the rubber pad.
[0038] like Figure 1 As shown, in some embodiments, the hollow holes 4 are of equal size but designed with varying depths, increasing in depth from the edges to the center. As pressure increases toward the center, the deeper hollow holes 4 provide greater room for deformation. When the rubber pad is subjected to significant pressure, the central hollow holes 4 can better accommodate deformation, distributing the pressure over a wider area and preventing stress concentration at a single point that could damage the rubber pad.
[0039] like Figure 2 As shown, in some embodiments, the wear-resistant surface layer 5 is a nitrile rubber layer. During use of the rubber pad, the edge ring 3 directly contacts external objects and generates friction. The nitrile rubber layer, as the wear-resistant surface layer 5, with its excellent wear resistance, can effectively resist this friction, reduce surface material loss, and prevent the rubber pad from thinning, cracking, or loss of sealing function due to wear, thereby significantly extending the service life of the rubber pad.
[0040] like Figure 3 As shown, in some embodiments, the vertical reinforcement 8 is shaped like an "I" (H). Within the buffering intermediate layer 6, the "I"-shaped vertical reinforcement 8 effectively resists pressure from above and below. When the rubber pad is subjected to pressure, the upper and lower lateral portions of the reinforcement disperse the pressure, distributing the concentrated pressure to a wider area, thereby preventing localized excessive pressure and deformation of the buffering intermediate layer 6. The central vertical portion acts like a sturdy pillar, enhancing the vertical compressive strength of the entire buffering intermediate layer 6. This ensures that the buffering intermediate layer 6 maintains structural stability even under high pressure, preventing it from collapsing or permanently deforming.
[0041] like Figure 3As shown, in some embodiments, the buffer middle layer 6 can be a natural rubber or butadiene rubber structural layer; whether it is natural rubber or butadiene rubber, its good elastic properties can enable the buffer middle layer 6 to play a buffering role when the rubber pad is subjected to pressure or impact.
[0042] like Figure 3 As shown, in some embodiments, the filling layer 9 may be glass fiber or aramid fiber. Due to the excellent chemical stability and heat resistance of glass fiber and aramid fiber, the filling layer 9 enables the pressure-bearing bottom layer 7 to operate under complex environmental conditions. For rubber mats used in chemical equipment, which may come into contact with various corrosive chemicals, or in high-temperature industrial environments, the filling layer 9 ensures that the pressure-bearing bottom layer 7 maintains its performance under these harsh conditions, preventing chemical corrosion or damage from high temperatures. This allows the entire rubber mat to adapt to a wider range of applications, improving its versatility and durability.
[0043] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
