Description

Technical Field

[0001] The present invention belongs to the technical field of equipment vibration reduction, and more specifically, relates to a multi-directional limiting tension and compression vibration reduction support and an assembly method. Background Art

[0002] With the continued vigorous development of my country's national economy and the accelerating pace of industrialization and urbanization, the scale and complexity of various types of equipment and facilities are showing a significant upward trend. Against this backdrop, the noise generated by equipment operation has become increasingly prominent, not only disrupting residents' daily lives but also having a serious negative impact on the surrounding environment. At the same time, the comfort level of the surrounding area has gradually become a key consideration for designers during the planning and design stages. Good comfort not only helps improve equipment efficiency but also provides a more pleasant working environment for operators, thereby improving overall work efficiency and quality.

[0003] In actual applications, many equipment and facilities currently lack any vibration reduction devices installed at the bottom, or only use simple vibration reduction devices with simple structures and limited functions. The vibration reduction effect of these existing devices is mostly unsatisfactory and cannot meet the strict requirements of modern equipment for efficient vibration reduction. The shortcomings of existing vibration reduction equipment are particularly prominent in equipment that requires extremely high operating accuracy and stability, such as precision machine tools and medical equipment, as well as in places that are extremely sensitive to noise control, such as hospitals, schools, and residential areas. These problems not only seriously affect the normal operation of equipment, resulting in shortened equipment lifespan and increased maintenance costs, but also cause great damage to the comfort of the surrounding environment, reduce the quality of life of residents, and may even cause a series of social problems.

[0014] Furthermore, the material of the intermediate support layer is selected from plastic material, rubber material or composite material with deformable properties.

[0015] Furthermore, the top and bottom of the vibration-damping disc layer are respectively in contact with the top flat plate and the bottom flat plate. The vibration-damping disc layer is composed of multiple disc layers, and each of the disc layers includes but is not limited to a spring, a disc spring or a shock-absorbing sheet.

[0016] According to a second aspect of the present invention, a method for assembling a multi-directional limit tension and compression vibration damping support is provided, which is implemented using the multi-directional limit tension and compression vibration damping support, comprising:

[0022] In general, the above technical solutions conceived by the present invention can achieve the following beneficial effects compared with the prior art:

[0023] 1. The multi-directional limited tension and compression vibration damping support of the present invention is achieved by arranging an annular variable thickness vibration damping layer between the top baffle and the bottom baffle, with a first annular cavity provided in the middle of the annular variable thickness vibration damping layer, in which an intermediate support layer is provided. The intermediate support layer is a circular structure with a second annular cavity in the middle, in which a pull rod damping device is provided. A vibration damping disc layer is provided between the vibration damping layer and the support layer. Through the synergistic effect of the annular variable thickness vibration damping layer, the vibration damping disc layer and the pull rod damping device, the vibration energy can be effectively absorbed and dispersed to adapt to vibrations of different frequencies. The intermediate support layer provides a stable central support for the structure, ensuring the compactness and reliability of the overall structure, so that it can still maintain a good working condition in a long-term vibration environment.

[0024] 2. The multi-directional limited tension and compression vibration damping support of the present invention has an annular variable thickness vibration damping layer made of two or more layers of rubber and one or more layers of stiffening steel plates alternately stacked and bonded by high-temperature vulcanization, which provides the support with the required suitable vertical and radial stiffness characteristics, and each layer of rubber is set to a different thickness. Through the structure of rubber layers with different thicknesses, it can accurately respond to vibrations of various frequencies and achieve variable frequency vibration reduction, thereby significantly improving the vibration reduction efficiency, effectively reducing the vibration energy during equipment operation, reducing damage to the equipment structure and components, and thus extending the service life of the equipment. At the same time, the alternating stacking of rubber layers and stiffening steel plates not only gives the vibration damping layer higher structural strength and stability, but also prevents the equipment from structural deformation or damage due to vibration, further enhancing the stability and reliability of the equipment.

[0025] 3. The multi-directional limiting tension and compression vibration damping support of the present invention nests the top baffle in the internal frame structure of the bottom baffle, and fixes a limiting block on the outer side of the lower end of the first lateral limiting plate and adjacent to the second lateral limiting plate. A lateral displacement gap of 5-10mm is reserved between the limiting block and the second lateral limiting plate. Once the lateral displacement amplitude of the device exceeds this reserved gap range, the limiting block will quickly and effectively play a role, thereby strictly limiting the lateral displacement of the equipment, so as to ensure the stability of the entire equipment during operation. After limiting the lateral displacement, the vibration caused by shaking of the equipment during operation is greatly reduced, which helps to reduce the noise level of the equipment, and can also reduce the wear and loosening of parts caused by vibration, thereby improving the overall stability and reliability of the equipment, and can effectively avoid equipment structure deformation and component damage caused by excessive lateral displacement.

[0026] 4. The multi-directional, limited-tension, and compression-tension vibration-damping bearing of this invention incorporates one or more vibration-damping discs between the annular variable-thickness vibration-damping layer and the intermediate support layer. These discs work in conjunction with the pull-rod damping device, effectively absorbing and dissipating vibration energy when vertical vibration occurs. Because the vibration-damping discs remain within their elastic deformation range throughout use, they avoid permanent deformation or damage, ensuring that they maintain excellent vibration-damping performance even after multiple vibration cycles.

[0027] 5. The multi-directional limiting tension and compression vibration-damping support of the present invention, the pull rod damping device is in the middle equilibrium position under normal working conditions. On the one hand, it can meet the specific requirements of some special equipment for tensile performance, ensuring that the equipment maintains structural stability and functionality when subjected to tension; on the other hand, when facing vertical vibration, the device can play an excellent role in vibration reduction and energy consumption, effectively reduce vibration energy, and ensure the stability of the equipment during operation, thereby taking into account the equipment's needs in both tensile resistance and vibration reduction, and improving the overall performance and reliability of the equipment.

[0039] Example 1

[0040] like Figure 1-6 As shown, an embodiment of the present invention provides a multi-directional limited tension and compression vibration damping bearing, comprising a top baffle 1, a bottom baffle 9 and an annular variable thickness vibration damping layer 3 arranged between the top baffle 1 and the bottom baffle 9, wherein a first annular cavity 10 is provided in the middle of the annular variable thickness vibration damping layer 3, and an intermediate support layer 7 is provided in the middle of the first annular cavity 10. The intermediate support layer 7 is a circular structure, and a second annular cavity 11 is provided in the middle thereof, and a pull rod damping device 4 is provided in the second annular cavity 11. Through the synergistic effect of the annular variable thickness vibration damping layer 3 and the pull rod damping device 4, vibration impacts of different sizes can be effectively buffered, and the bearing is suitable for a variety of vibration environments. At the same time, the top baffle 1, the bottom baffle 9 and the intermediate support layer 6 of the bearing jointly play a limiting role to prevent excessive deformation of the bearing and ensure structural stability. The overall structural design is reasonable and can adapt to a variety of working conditions. Whether it is static load support or dynamic vibration environment, it can maintain good performance. It is widely applicable to scenes such as bridges, high-rise buildings, mechanical equipment and offshore platforms, effectively protecting structural safety and reducing vibration damage.

[0041] Furthermore, the top baffle 1 includes a top flat plate 101, which is rectangular in shape. The first lateral limit plates 102 are fixedly installed around the bottom of the top flat plate 101, and the first lateral limit plates 102 are perpendicular to the top flat plate 101. The top flat plate 101 and the first lateral limit plates 102 around it form a downward-opening frame structure, and a receiving slot is formed inside the frame, which plays a limiting and guiding role for the annular variable thickness vibration damping layer 3.

[0042] Furthermore, the bottom baffle 9 includes a bottom flat plate 901, which is rectangular in shape. Second lateral limiting plates 902 are fixedly installed around the top of the bottom flat plate 901, and the second lateral limiting plates 902 are perpendicular to the bottom flat plate 901. The bottom flat plate 901 and the second lateral limiting plates 902 around it form an upwardly open frame structure, and a receiving slot is formed inside the frame to limit the top baffle 1.

[0043] Furthermore, the top baffle 1 is nested in the internal frame structure of the bottom baffle 9, forming a lateral limiting structure, wherein the first lateral limiting plate 102 and the second lateral limiting plate 902 are parallel to each other, and the lower end of the first lateral limiting plate 102 is adjacent to the upper end of the second lateral limiting plate 902, and a limiting block 5 is fixedly installed on the outer side of the lower end of the first lateral limiting plate 102 and adjacent to the second lateral limiting plate 902. A lateral displacement gap of 5-10 mm is reserved between the limiting block 5 and the second lateral limiting plate 902. Once the lateral displacement amplitude of the device exceeds the reserved gap range, the limiting block 5 will quickly and effectively play a role, thereby strictly limiting the lateral displacement of the equipment, so as to ensure the stability of the entire equipment during operation. After limiting the lateral displacement, the vibration caused by shaking of the equipment during operation is greatly reduced. This not only helps to reduce the noise level of the equipment, but also reduces the wear and looseness of parts caused by vibration, thereby improving the overall stability and reliability of the equipment, and can effectively avoid deformation of the equipment structure and damage to parts caused by excessive lateral displacement. For example, excessive lateral displacement may cause the connection parts to loosen, the welding points to crack, or the key components to shift, and the setting of the limit block 5 can effectively prevent these problems from occurring, thereby extending the service life of the equipment, reducing the maintenance cost of the equipment, and improving the operating efficiency of the equipment, bringing higher economic benefits to the enterprise or user. The limitation of lateral displacement reduces the vibration source of the equipment during operation, thereby reducing the noise level of the equipment. This is especially important for some equipment that needs to operate in a quiet environment. It can provide a more comfortable working environment for operators and also help reduce noise pollution to the surrounding environment.

[0044] Furthermore, a first sealing steel plate 2 is fixedly installed on the bottom of the top flat plate 101, an upper groove is opened at the top center of the first sealing steel plate 2, and a through hole is provided at the center of the upper groove, and a second sealing steel plate 8 is fixedly installed on the top of the bottom flat plate 901, a lower groove is opened at the bottom center of the second sealing steel plate 8, and a through hole is provided at the center of the lower groove, and the two ends of the pull rod damping device 4 are arranged in the upper groove and the lower groove, ensuring the precise positioning of the pull rod damping device 4 during installation and use, and reducing structural instability caused by installation errors.

[0045] Furthermore, the annular variable-thickness vibration-damping layer 3 is disposed between the first sealing steel plate 2 and the second sealing steel plate 8. The annular variable-thickness vibration-damping layer 3 is formed by alternating two or more layers of rubber and one or more layers of stiffening steel plates, bonded by high-temperature vulcanization, to provide the support with the required appropriate vertical and radial stiffness characteristics. Each layer of rubber is set to a different thickness. Through the structure of rubber layers of different thicknesses, it can accurately respond to vibrations of various frequencies and achieve variable-frequency vibration reduction, thereby significantly improving vibration reduction efficiency, effectively reducing vibration energy during equipment operation, and reducing damage to equipment structures and components, thereby extending the service life of the equipment. At the same time, the alternating lamination of rubber layers and stiffening steel plates not only gives the vibration-damping layer higher structural strength and stability, but also prevents structural deformation or damage to the equipment due to vibration, further enhancing the stability and reliability of the equipment. This design can also effectively reduce the interference of vibration on the operating accuracy of the equipment, improve the processing, measurement, or operation accuracy of the equipment, enable it to better adapt to complex working conditions, and maintain a good operating state. In addition, rubber layers of varying thickness can absorb and disperse vibration energy, reduce vibration transmission, and lower equipment operating noise, providing operators with a more comfortable working environment and reducing the potential health hazards of noise.

[0046] Furthermore, the central axis of the annular variable thickness vibration damping layer 3 coincides with the central axis of the intermediate support layer 7, and the top and bottom of the intermediate support layer 7 abut against the top plate 101 and the bottom plate 901, respectively. During use, the support layer not only provides structural stability but also coordinates with the deformation of the annular variable thickness vibration damping layer 3 to ensure uniformity and consistency of the vibration damping effect. The material of the intermediate support layer 7 is selected from a deformable plastic material, rubber material, or composite material. The plastic material includes thermoplastics, thermosetting plastics, elastomers, etc. The rubber material includes natural rubber (NR), styrene-butadiene rubber (SBR), nitrile rubber (NBR), chloroprene rubber (CR), silicone rubber, etc. The composite material includes rubber-metal composites, rubber-fiber composites, fiber-reinforced plastic materials, etc.

[0047] Furthermore, the top plate 101 is provided with multiple screw holes, which penetrate the first sealing steel plate 2 and extend to the first stiffening steel plate of the annular variable thickness vibration damping layer 3. Countersunk bolts securely connect the annular variable thickness vibration damping layer 3 to the top plate 101. The bottom plate 901 is also provided with multiple screw holes, which penetrate the second sealing steel plate 8 and extend to the last stiffening steel plate of the annular variable thickness vibration damping layer 3. Countersunk bolts securely connect the annular variable thickness vibration damping layer 3 to the bottom plate 901. This connection method tightly integrates the top baffle 1, the annular variable thickness vibration damping layer 3, and the bottom baffle 9 into a single, integrated structure, enhancing overall structural stability. The bolted connection forms a stable, integrated structure, reducing relative displacement and looseness between components and improving the stability of the device under high loads and complex operating conditions. Furthermore, the precise connection ensures that the vibration damping layer can more effectively absorb and dissipate vibration energy, reducing vibration interference with the equipment's operating accuracy, reducing equipment noise, and improving working environment comfort.

[0048] Furthermore, one or more vibration-damping disc layers 6 are provided in the first annular cavity 10. The one or more vibration-damping disc layers 6 are provided between the annular variable-thickness vibration-damping layer 3 and the intermediate support layer 7, and the top and bottom of the vibration-damping disc layers 6 abut against the top plate 101 and the bottom plate 901, respectively. Their primary function is to work in conjunction with the tie rod damping device 4, playing an important role in vertical vibration reduction and energy dissipation. During use, the deformation of the support never exceeds the maximum deformation limit of the vibration-damping disc layer 6, ensuring that the vibration-damping disc layer 6 remains in the elastic deformation stage throughout its entire service life, maintaining its stable performance and enabling cyclical use. This ensures the continuity and reliability of the vibration-damping effect, improves the efficiency and durability of the vibration-damping system, reduces maintenance costs, and enhances the stability and reliability of the entire device. The design of the vibration-damping disc layer 6 takes into account the synergistic effect with the tie rod damping device 4, so that when vertical vibration occurs, the two can cooperate with each other to efficiently absorb and dissipate vibration energy. Since the vibration-damping disc layer 6 is always kept within the elastic deformation range during the entire use process, it will not be permanently deformed or damaged, which ensures that it can still maintain good vibration-damping performance after multiple vibration cycles.

[0049] Furthermore, the vibration-damping disc layer 6 is composed of multiple disc layers, each of which includes but is not limited to a spring, a disc spring, or a damping sheet. The disc layer primarily cooperates with the pull rod damping device 4 to facilitate vertical vibration reduction and energy dissipation. During use, the deformation of the device is always controlled within the maximum deformation limit of the vibration-damping disc layer 6, ensuring that the vibration-damping disc layer 6 remains in the elastic deformation stage throughout its entire use cycle, thereby ensuring that the vibration-damping disc layer 6 can continuously and stably perform its vibration-damping function.

[0050] Furthermore, the pull rod damping device 4 is in an intermediate equilibrium position during normal operation. In practical applications, it can, on the one hand, meet the specific tensile strength requirements of some special equipment, ensuring that the equipment maintains structural stability and functionality when subjected to tension. On the other hand, when facing vertical vibration, the device can also play an excellent role in vibration reduction and energy dissipation, effectively reducing vibration energy and ensuring the stability of the equipment during operation. Thus, it takes into account the equipment's requirements for both tensile strength and vibration reduction, and improves the overall performance and reliability of the equipment.

[0051] Specifically, the tie rod damping device 4 includes but is not limited to a hydraulic damping tie rod damping device, a pneumatic damping tie rod damping device, and a friction damping tie rod damping device. The hydraulic damping tie rod damping device constructs a chamber structure and a throttling channel inside the damper. When the tie rod moves, it drives the piston to move in the chamber, forcing the hydraulic oil to pass through a specific throttling hole, and utilizes the throttling effect during the flow of the hydraulic oil to generate a damping force, thereby achieving buffering and control of the tie rod movement. The device can accurately regulate and stabilize the damping force output characteristics, and can effectively suppress the impact and vibration generated by the tie rod during the reciprocating motion; the pneumatic damping tie rod damping device utilizes the compressibility of the gas and sets a piston structure in the damping chamber. When the tie rod moves, the piston moves accordingly, changing the volume of the gas in the damping chamber, causing the gas to compress or expand, and generating a damping force based on the change in the gas state, thereby achieving damping control of the tie rod movement. The device has the significant advantage of fast response speed, and can quickly buffer and absorb the instantaneous impact on the tie rod. Its structure is relatively simple and easy to manufacture. The cost is low and the overall weight is light; the friction damping type tie rod damping device sets a friction component between the tie rod and the fixed component, such as installing a friction plate on the surface of the tie rod. When the tie rod moves, relative sliding occurs between the friction plate and the fixed component, and the friction between the two is used to form a damping force, thereby achieving obstruction and buffering of the tie rod movement. The device has a simple structural design, low manufacturing cost, and easy installation and maintenance. It is suitable for occasions where damping accuracy is not required and the working environment is relatively harsh, such as tie rod systems used for earthquake resistance in building structures; the electromagnetic damping type tie rod damping device is based on the law of electromagnetic induction. A relative motion structure of a coil and a magnet is set in the device. When the tie rod moves, it drives the coil or magnet to produce relative displacement, causing the conductor to cut the magnetic flux lines in the magnetic field, generating an induced current. The induced current is acted upon by the Ampere force in the magnetic field to form a damping force, thereby achieving control of the tie rod movement. The damping force can be precisely adjusted by precisely controlling the current size. The response speed is extremely fast, and the damping force can be adjusted in real time according to the movement state of the tie rod.
