Description

Technical Field

[0001] This utility model belongs to the field of vibration reduction technology, specifically relating to a high-strength rubber vibration damping component. Background Technology

[0002] With societal progress and increased industrialization, mechanical equipment is increasingly widely used in daily production and life. However, the mechanical vibrations generated during the operation of this equipment, especially those transmitted through the base plate, often damage the installation foundation. To address this issue, modern engineering practice commonly employs the solution of installing vibration damping devices at the bottom of the equipment. Among various vibration damping materials, rubber is the preferred material due to its excellent damping performance. Rubber vibration damping elements not only have good vibration attenuation characteristics but also effectively isolate noise and provide buffer protection. In terms of material selection, vibration damping products mainly use natural rubber as the base material. To meet the needs of different working conditions, synthetic rubbers with special properties are also selected: neoprene rubber can improve heat resistance, butyl rubber has excellent damping characteristics, and EPDM rubber exhibits better weather resistance. However, the damping efficiency of existing traditional vibration damping components mainly depends on the physical properties of the selected materials. Inhomogeneity of materials during production can affect the damping efficiency of the components, leading to a shortened service life.

[0003] Chinese utility model patent CN217002883U discloses a high-strength rubber shock absorber, including a central rubber component. An mounting groove is formed on the inner side of the central rubber component, and a shock-absorbing spring is installed inside the mounting groove. A gap exists between the outer side of the shock-absorbing spring and the inner side of the mounting groove. The shock-absorbing springs are circumferentially distributed along the centerline of the central rubber component. Several vent holes are formed on the top surface and periphery of the central rubber component, evenly distributed and independent of each other. In this design, the shock-absorbing springs are utilized by forming several mounting grooves on the inner side of the central rubber component, arranging multiple shock-absorbing springs circumferentially within the grooves. This further enhances the shock absorption effect of the rubber component. Simultaneously, the gap between the mounting groove and the shock-absorbing spring allows the rubber to have some rebound space when compressed, improving the service life of the rubber shock absorber. However, the presence of vent holes allows moisture to enter the shock absorber, corroding the shock-absorbing springs and other metal components, thus shortening its service life.

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.

[0017] Example 1:

[0018] This utility model provides a high-strength rubber shock absorber, comprising an outer buffer rubber 1. The outer buffer rubber 1 is fixedly installed with an upper support plate 2 and a lower support plate 3 via an insert injection molding process. The upper support plate 2 is provided with a stud 4 and a sleeve 5, and the lower support plate 3 is provided with a guide post 6, which is movably connected to the sleeve 5. The outer buffer rubber 1 has a cavity 7 inside, and a spring 8 is fixedly installed in the cavity 7. The two ends of the spring 8 elastically abut against the upper support plate 2 and the lower support plate 3 respectively. An inner buffer rubber 9, made of silicone rubber, is fixedly connected to the outer buffer rubber 1 inside and between the upper support plate 2 and the lower support plate 3 via an insert injection molding process. The outer buffer rubber 1 is made of styrene-butadiene rubber. The bottom of the outer buffer rubber 1 has anti-slip texture 10. The upper support plate 2 and the lower support plate 3 are both made of stainless steel.

[0019] Through the above technical solution, the outer buffer rubber 1 of this utility model is fixedly installed with an upper support plate 2 and a lower support plate 3 by an insert injection molding process. The upper support plate 2 is provided with a stud 4 and a sleeve 5. The stud 4 facilitates the fixed connection of this utility model with the equipment. The lower support plate 3 is provided with a guide post 6. The guide post 6 cooperates with the sleeve 5 to form a cylinder structure, which provides shock absorption performance. A spring 8 is fixedly installed in the outer buffer rubber 1. The two ends of the spring 8 elastically abut against the upper support plate 2 and the lower support plate 3 respectively, further providing shock absorption performance. Combined with the elastic physical properties of the outer buffer rubber 1 material, a composite shock absorption structure is formed, which improves the service life of the shock absorption component.

[0020] Example 2:

[0021] The shock absorber in this embodiment adopts a composite shock absorption structure design, achieving efficient shock absorption through the synergistic effect of rubber material and metal spring 8. The main structure of the shock absorber consists of an outer buffer rubber 1, which is made of high-strength rubber material and molded by compression molding. A cylindrical cavity 7 is provided inside the outer buffer rubber 1, which extends along the axial direction of the shock absorber and runs through the entire height of the shock absorber. A helical compression spring 8 is fixedly installed in the cavity 7, and the two ends of the spring 8 maintain elastic contact with the upper support plate 2 and the lower support plate 3, respectively.

[0022] The upper support plate 2 is fixedly embedded in the upper part of the outer buffer rubber 1 through an insert injection molding process, forming a stable mechanical connection. The upper support plate 2 is made of metal sheet by stamping, and a stud 4 is vertically set at its center. This stud 4 is used for bolt connection with the equipment to be damped. Multiple sleeve structures 5 are evenly distributed around the stud 4. These sleeves 5 are integrally formed with the upper support plate 2 and extend downward. The inner wall of the sleeve 5 is precision machined to form a smooth guide surface to ensure smooth fit with the guide post 6.

[0023] The lower support plate 3 is also fixed to the bottom of the outer buffer rubber 1 via insert injection molding, and its structure corresponds to that of the upper support plate 2. The lower support plate 3 is provided with the same number of guide posts 6 as the sleeves 5. These guide posts 6 extend upwards and insert into the corresponding sleeves 5. An appropriate clearance is maintained between the guide posts 6 and the sleeves 5, forming a sliding pair structure similar to a cylinder. When subjected to vibration loads, the guide posts 6 can slide axially within the sleeves 5, while the outer buffer rubber 1 undergoes elastic deformation, achieving a preliminary shock absorption effect.

[0024] Spring 8, as the second-stage damping element, has its two ends abutting against the corresponding contact surfaces of the upper support plate 2 and the lower support plate 3, respectively. The pre-compression of spring 8 is precisely calculated to ensure that it maintains appropriate initial pressure even under static load. When the damping element is subjected to dynamic load, spring 8 absorbs vibration energy through compression deformation, while simultaneously suppressing vibration transmission through elastic restoring force. The synergistic effect of spring 8 and outer buffer rubber 1 forms a composite damping mechanism, significantly improving damping efficiency.

[0025] The overall structural design of the shock absorber fully considers load distribution and stress concentration. The wall thickness of the outer buffer rubber 1 gradually increases from the center to the edge, forming an optimized stress gradient distribution. The edges of both the upper support plate 2 and the lower support plate 3 are designed with reinforcing flanges, which are embedded inside the outer buffer rubber 1, significantly improving the strength of the connection. The mating length of the sleeve 5 and the guide post 6 is specially designed to ensure sufficient guiding contact area under any working condition, preventing wear caused by off-center loading.

[0026] During operation, this damping component first absorbs high-frequency vibrations through the elastic deformation of the outer buffer rubber 1, and then attenuates low-frequency vibrations through the compression deformation of the spring 8. The sliding pair composed of the guide post 6 and the sleeve 5 not only provides guidance but also further dissipates vibration energy through frictional damping generated by relative motion. This multi-stage damping mechanism enables the damping component to effectively cope with vibrations of various frequencies, while avoiding the performance fluctuation problems caused by material inhomogeneity in traditional damping components.

[0027] The sealing performance of the shock absorber is significantly improved, with the outer cushioning rubber 1 completely encapsulating the metal components, forming a reliable anti-corrosion barrier. Compared with existing technologies, this design eliminates the vent structure, fundamentally preventing moisture intrusion and corrosion of the metal components. The insert injection molding process ensures a molecular-level bond between the metal and rubber, avoiding interface separation that may occur with traditional bonding methods. This integrated structural design significantly extends the service life of the shock absorber, making it particularly suitable for long-term use in humid or corrosive environments.

[0028] Example 3:

[0029] This embodiment utilizes a double-layer elastomer of outer buffer 1 and inner buffer 9, combined with a metal support assembly, to form a multi-stage vibration damping system. The outer buffer 1 uses an insert injection molding process to encapsulate and fix the upper support plate 2 and lower support plate 3, forming an integral vibration damping frame. The studs 4 on the upper support plate 2 are used for equipment installation and fixation. Their sleeve 5 structure and the guide post 6 of the lower support plate 3 form a sliding piston mechanism, enabling axial displacement damping under impact loads. The spring 8 assembly is installed in the internal cavity 7 of the outer buffer 1, with its two ends elastically contacting the upper and lower support plates 3 respectively, forming a mechanical damping layer.

[0030] The inner buffer rubber 9 is embedded inside the outer buffer rubber 1 through a secondary injection molding process, located in the core stress-bearing area between the upper and lower support plates 3. This silicone rubber inner buffer rubber 9 has a unique molecular chain structure, and the free rotation capability between its molecular chains gives it excellent energy absorption characteristics under dynamic loads. When the shock absorber is subjected to vertical vibration impact, the viscoelastic properties of the inner buffer rubber 9 enable it to convert mechanical energy into heat energy for dissipation. Simultaneously, its compression deformation generates radial expansion force on the outer buffer rubber 1, enhancing the overall structural stability. The inner buffer rubber 9 and the outer buffer rubber 1 complement each other in terms of material properties; the high damping characteristics of silicone rubber combined with the high resilience of the main rubber effectively broadens the damping frequency band.

[0031] In dynamic operation, when the equipment generates high-frequency vibrations, the inner buffer rubber 9 first absorbs the high-frequency vibration energy through the shear deformation of its molecular chains. When encountering large-amplitude impacts, the spring 8 assembly begins to function, storing and slowly releasing the impact energy through elastic deformation. The piston mechanism between the upper and lower support plates 3 generates an air damping effect during movement, further dissipating vibration energy. This composite damping mechanism achieves a full-frequency damping effect from high-frequency small-amplitude to low-frequency large-amplitude vibrations. The embedding position of the inner buffer rubber 9 is precisely calculated to place it in the area where the stress distribution of the damping component is most concentrated, thereby maximizing material utilization.

[0032] The structural feature of this damping component lies in its layered energy dissipation mechanism. The outermost rubber material provides initial cushioning and sealing protection; the middle layer of silicone rubber inner buffer 9 is responsible for absorbing and converting the main vibration energy; and the core metal spring 8 assembly withstands extreme impact loads. This design avoids the performance limitations of a single damping material under complex working conditions, achieving optimized damping performance through material combination. The interface between the inner buffer 9 and the outer buffer 1 adopts a molecular-level interpenetrating network structure, forming chemical bonds during injection molding, ensuring that the two layers do not delaminate under long-term dynamic loads.

[0033] The damping components exhibit adaptive damping characteristics during operation. Under light loads, energy is primarily absorbed through the elastic deformation of the inner buffer rubber 9. As the load increases, the spring 8 assembly gradually participates in damping, creating nonlinear stiffness characteristics. This variable stiffness design ensures both damping sensitivity under light loads and sufficient support strength under heavy loads. The silicone rubber formulation of the inner buffer rubber 9 is specially optimized to match its glass transition temperature range with common mechanical vibration frequencies, thus achieving optimal damping performance under ambient temperature conditions. Through the synergistic effect of material combination and structural design, the entire damping system achieves the orderly transfer and conversion of vibration energy across multiple levels, ultimately dissipating it into the environment as heat.

[0034] Example 4:

[0035] In this embodiment, the outer buffer rubber 1 is made of styrene-butadiene rubber. This shock absorber is firmly bonded to the metal components using an insert injection molding process, forming an integral shock-absorbing structure. The outer buffer rubber 1 has a cylindrical chamber 7 inside, within which a high-strength compression spring 8 is vertically installed. The upper end of the spring 8 is in elastic contact with the upper support plate 2, and the lower end is in elastic contact with the lower support plate 3. The upper support plate 2 has a stud 4 in its center for fixed connection with the device to be damped. Four sleeves 5 are evenly distributed around the stud 4. The lower support plate 3 has four guide posts 6 at corresponding positions. The guide posts 6 and sleeves 5 form a precise sliding fit, constituting a cylinder-like guiding structure.

[0036] When the equipment vibrates, the vibration energy is transferred to the upper support plate 2 through the stud 4, and then absorbed by the combined action of the spring 8 and the styrene-butadiene rubber outer buffer 1. The coordinated movement of the guide post 6 and the sleeve 5 ensures that the vibration damping process maintains a linear trajectory, avoiding wear caused by lateral displacement. The styrene-butadiene rubber outer buffer 1 undergoes elastic deformation during vibration, converting some of the mechanical energy into heat energy for dissipation. At the same time, the flexible properties of its molecular chains can effectively absorb high-frequency vibrations. The spring 8 mainly undertakes the buffering function for low-frequency vibrations, realizing energy conversion through its compression and rebound characteristics.

[0037] The synergistic effect of the two damping mechanisms significantly improves the damping performance and service life. The outer buffer rubber 1 adopts an overall encapsulation design, completely sealing the internal metal components, effectively preventing the intrusion of external moisture and corrosive media, and protecting metal components such as spring 8 from corrosion. The selection of styrene-butadiene rubber gives it excellent wear resistance and anti-aging properties, maintaining stable damping performance during long-term use.

[0038] When the vibration damper is working, the equipment vibration is first transmitted to the upper support plate 2 through the stud 4, and then the energy is dissipated through three paths: first, the compression and rebound of the spring 8; second, the elastic deformation of the styrene-butadiene rubber; and third, the frictional damping generated by the relative motion between the guide post 6 and the sleeve 5. This composite vibration damping mechanism can adapt to vibration conditions of different frequencies and amplitudes, and achieve a wide-band vibration damping effect.

[0039] The high strength of styrene-butadiene rubber (SBR) ensures that the damping component maintains its structural integrity even under heavy loads, while the benzene ring side groups in its molecular structure provide excellent mechanical strength and elastic recovery. The overall structural design of the damping component enables it to dampen vibrations in all three axes. Vertical damping is primarily achieved through the compression deformation of the spring 8 and the rubber, while horizontal damping relies on the shear deformation of the SBR. This multi-directional damping characteristic allows it to effectively address vibration problems under complex operating conditions. The one-piece molding process of the outer buffer rubber 1 eliminates the joint weaknesses commonly found in traditional damping components, improving the product's reliability and durability.

[0040] Styrene-butadiene rubber's oil and chemical resistance makes it suitable for various industrial environments, including those containing oil or chemical reagents. The installation of the shock absorber is simple; it only requires fixing it to the equipment via the studs 4 on the upper support plate 2, while the lower support plate 3 contacts the foundation surface for immediate use.

[0041] During use, the styrene-butadiene rubber outer buffer 1 automatically adjusts its damping characteristics according to temperature changes, maintaining sufficient flexibility at low temperatures and appropriate stiffness at high temperatures. This temperature-adaptive characteristic greatly expands the applicable temperature range of the shock absorber. The precise fit between the guide post 6 and the sleeve 5 not only provides motion guidance but also generates an additional damping effect through metal-to-metal friction, further enhancing the shock absorption performance.

[0042] The pre-compression design of spring 8 ensures that the shock absorber has initial damping capacity under static load, effectively suppressing the instantaneous impact during equipment startup. The surface of the styrene-butadiene rubber outer buffer 1 can be designed with anti-slip textures 10 to increase friction with the mounting base and prevent displacement of the shock absorber during operation. The entire shock absorber has a compact structure, occupies little space, and is easy to install and use in various space-constrained environments.

[0043] Example 5:

[0044] In this embodiment, the bottom of the outer cushioning rubber 1 is provided with an anti-slip texture 10 structure, which is integrally formed with the outer cushioning rubber 1 through a molding process. The anti-slip texture 10 adopts an interlaced wave-shaped pattern design, with the texture depth evenly distributed within the range of 2-5mm and the texture spacing maintained at an equidistant distribution of 10-15mm. This specifically designed anti-slip texture 10 can significantly increase the friction coefficient between the shock absorber and the mounting base, effectively preventing the displacement of the shock absorber caused by vibration during equipment operation.

[0045] The wavy structure of the anti-slip texture 10 provides multi-directional anti-slip properties, ensuring a stable anti-slip effect regardless of the direction of equipment vibration. The depth design of the texture ensures sufficient anti-slip performance while avoiding affecting the overall structural strength of the shock absorber due to excessive texture depth. In practical applications, when the equipment vibrates, the outer buffer rubber 1 undergoes elastic deformation. At this time, the anti-slip texture 10 on the bottom can firmly "engage" with the mounting base surface, preventing the shock absorber from sliding.

[0046] The anti-slip texture 10 structure is particularly suitable for vibration damping components installed on smooth base surfaces (such as ceramic tiles, metal plates, etc.). In humid environments, the drainage channels formed by the anti-slip texture 10 can promptly remove accumulated water, preventing the water film effect from reducing the coefficient of friction. Simultaneously, the wavy design of the anti-slip texture 10 can absorb lateral vibration energy to a certain extent, working in conjunction with the vertical damping function of the vibration damping component to achieve multi-directional vibration damping effects.

[0047] The anti-slip texture 10 and the outer cushioning rubber 1 are integrally molded from the same material, ensuring the overall structural durability. During use, the anti-slip texture 10 will undergo elastic deformation along with the outer cushioning rubber 1, but will not crack or fall off. This design maintains the overall damping performance of the shock absorber while increasing its stability, making it particularly suitable for vibration damping applications in industrial equipment that are subjected to long-term vibration loads.

[0048] The arrangement density of the anti-slip texture 10 is optimized to ensure anti-slip performance without excessively increasing the hardness distribution at the bottom of the shock absorber. This balanced design ensures that the shock absorber maintains good overall damping performance while providing anti-slip protection. When equipment vibration is transmitted to the shock absorber, the anti-slip texture 10 structure does not significantly hinder the elastic deformation of the shock absorber, ensuring the overall coordination of the damping system.

[0049] The anti-slip texture 10 structure exhibits excellent anti-slip performance in practical applications, effectively preventing displacement of the shock absorber even under vibration conditions with large amplitude. Simultaneously, the wavy design of the anti-slip texture 10 facilitates cleaning and maintenance, preventing the accumulation of dust and debris, and maintaining good anti-slip performance even after long-term use. This design significantly improves the adaptability and reliability of the shock absorber in various installation environments.

[0050] Example 6:

[0051] In this embodiment, the external buffer 1 uses an insert injection molding process to firmly fix the upper support plate 2 and the lower support plate 3 inside. The upper support plate 2 is made of stainless steel, with a stud 4 structure for equipment connection on its upper part and a sleeve 5 assembly extending from its lower part. The lower support plate 3 is also made of stainless steel, with a guide post 6 structure on its upper part that mates with the sleeve 5. The guide post 6 and the sleeve 5 form a precisely fitted sliding connection mechanism, constituting a shock-absorbing motion pair similar to a cylinder.

[0052] The core damping mechanism of this shock absorber consists of three parts: first, a mechanical damping structure formed by the sliding fit of the guide post 6-sleeve 5 between the upper stainless steel support plate 2 and the lower support plate 3; second, a compression spring 8 installed in the internal cavity 7 of the outer buffer rubber 1, with its two ends abutting against the upper support plate 2 and the lower support plate 3 respectively; and finally, the elastic deformation capacity of the outer buffer rubber 1 itself. These three damping mechanisms work together to absorb and buffer the vibration energy from the equipment.

[0053] In the assembly process, the upper stainless steel support plate 2 and the lower stainless steel support plate 3 are pre-positioned in the injection mold as inserts. Molten rubber material is then injected into the mold, and after cooling and solidification, a complete shock-absorbing component is formed. This manufacturing process ensures a strong bond between the metal parts and the rubber material, avoiding the delamination problems that may occur with traditional bonding methods. The use of stainless steel not only guarantees structural strength but also significantly improves the corrosion resistance of the components.

[0054] When the damping components bear vibration loads from the equipment, the vibration energy is first transmitted to the entire damping system through the studs 4 of the upper support plate 2. At this time, the relative sliding of the guide post 6 within the sleeve 5 generates the first damping effect; simultaneously, the spring 8 is compressed and deformed, absorbing some of the vibration energy; and the elastic deformation of the outer buffer rubber 1 further dissipates the remaining vibration energy. This multi-stage damping mechanism effectively reduces the vibration amplitude transmitted to the mounting foundation.

[0055] The use of stainless steel brings significant advantages to this shock absorber: First, the high strength of stainless steel ensures that the upper support plate 2 and the lower support plate 3 will not undergo plastic deformation under long-term vibration loads; second, the excellent corrosion resistance of stainless steel enables the shock absorber to adapt to harsh environments such as humidity and corrosiveness; third, the difference in the coefficient of thermal expansion between stainless steel and rubber is small, reducing the impact of temperature changes on the bonding strength of the components.

[0056] The vibration damping component of this embodiment is particularly suitable for industrial equipment requiring long-term stable operation. In practical applications, the stainless steel upper support plate 2 is fixedly connected to the equipment base via studs 4, while the lower support plate 3 contacts the mounting foundation. When the equipment is running, the vibration generated is transmitted to the vibration damping system through the upper support plate 2. After the synergistic effect of the triple vibration damping mechanism, the vibration energy ultimately transmitted to the foundation is significantly reduced, thereby effectively protecting the mounting foundation from vibration damage.
