Abstract
Description
Technical Field
[0001] This utility model relates to vibration isolation and buffering technology, specifically a composite damping rubber wire rope vibration isolator. Background Technology
[0002] Wire rope vibration isolators, also known as wire rope dampers, are made by winding a steel wire rope into a spiral shape and fixing it between two metal plates arranged along a nut. Their stiffness and damping depend on the diameter, number of strands, number of turns, winding method, and dimensions of the wire rope. It is a new type of vibration isolator with nonlinear characteristics and dry friction damping, often used as a key component in airborne, vehicle-mounted, and shipborne electronic and mechanical equipment.
[0003] However, existing wire rope vibration isolators rely on dry friction between steel wires to generate damping, which is relatively weak. When encountering a large impact, the upper and lower metal plates are prone to direct collision, which not only easily causes damage but also generates secondary vibrations and impacts. Utility Model Content
[0004] To overcome the shortcomings of the prior art, this utility model provides a composite damping rubber wire rope vibration isolator with good impact resistance and can quickly recover after withstanding large impact deformation.
[0005] To achieve the above technical objectives, this utility model adopts the following technical solution: a composite damping rubber wire rope vibration isolator, comprising a base plate, a damping module, and a top plate. The damping module is located between the base plate and the top plate. The damping module includes a buffer unit and a rubber block, with the rubber block covering the outside of the buffer unit. The buffer unit includes an upper mounting block, a lower mounting block, and two wire ropes. The upper mounting block is fixed below the top plate, and the lower mounting block is fixed above the base plate. The upper mounting block has several upper through holes on both sides, and the lower mounting block has several lower through holes on both sides. The two wire ropes are located on both sides of the upper mounting block. One end of each wire rope is fixed to the upper mounting block, and the other end of each wire rope passes through the lower through hole and the upper through hole in sequence before being fixed to the upper mounting block. The wire ropes are arranged in a coil shape.
[0006] Preferably, the top plate has a mounting hole in the middle.
[0007] Preferably, the top plate has positioning holes on both sides, and positioning pins are fitted into the positioning holes, with the positioning pins located on the top of the rubber block.
[0008] Preferably, both ends of the lower mounting block are provided with limiting plates.
[0009] Preferably, the base plate has assembly holes at both ends, and assembly pins are provided in the assembly holes, which are fixed to the limiting plate.
[0010] Preferably, a buffer block is provided below the upper mounting block.
[0011] Preferably, the upper mounting block is fixedly connected to the top plate and the lower mounting block is fixedly connected to the bottom plate by locking bolts.
[0012] Preferably, the base plate has fixing holes on both sides.
[0013] Preferably, the rubber block has a deformation hole in the middle, the deformation hole passing through the rubber block and through a coiled steel wire rope.
[0014] In summary, this utility model achieves the following technical effects:
[0015] The composite damping rubber-steel wire rope vibration isolator of this utility model uses rubber blocks to cover the outside of the coiled steel wire rope, so that the steel wire rope and rubber blocks form a composite damping, which has good impact resistance, can quickly recover after large impact deformation, is not easily damaged, and has a long service life.

[0026] Example 1:
[0027] like Figure 1As shown in Figure 3, a composite damping rubber-steel wire rope vibration isolator includes a base plate 1, a damping module, and a top plate 3. The damping module is located between the base plate 1 and the top plate 3. The damping module includes a buffer unit and a rubber block 2, with the rubber block 2 covering the outside of the buffer unit. The buffer unit includes an upper mounting block 9, a lower mounting block 11, and two steel wire ropes 10. The upper mounting block 9 is fixed below the top plate 3, and the lower mounting block 11 is fixed above the base plate 1. The upper mounting block 9 has several upper through holes on both sides, and the lower mounting block 11 has several lower through holes on both sides. The two steel wire ropes 10 are located on both sides of the upper mounting block 9. One end of the steel wire rope 10 is fixed to the upper mounting block 9, and the other end of the steel wire rope 10 passes through the lower through hole and the upper through hole in sequence before being fixed to the upper mounting block 9. The steel wire rope 10 is arranged in a coil shape.
[0028] The wire rope 10 is coiled, which increases the number of wire rope segments between the upper mounting block 9 and the lower mounting block 11, thereby increasing its strength and impact resistance.
[0029] The composite damping rubber steel wire rope 10 vibration isolator of this utility model uses a rubber block 2 to cover the outside of the coiled steel wire rope 10, so that the steel wire rope 10 and the rubber block 2 form a composite damping, which has good impact resistance, can quickly recover after large impact deformation, is not easily damaged, and has a long service life.
[0030] The top plate 3 has a mounting hole 4 in the middle; the mounting hole 4 is provided to facilitate the installation of the top plate 3 in a preset position.
[0031] The top plate 3 has positioning holes 6 on both sides, and positioning pins are fitted into the positioning holes 6. The positioning pins are located on the top of the rubber block 2.
[0032] Both ends of the lower mounting block 11 are provided with limiting plates 12; the limiting plates 12 are provided to increase the contact area between the rubber block 2 and the lower mounting block 11, thereby increasing the strength of the rubber block 2 and the connection firmness with the lower mounting block 11; at the same time, they increase the strength to withstand lateral forces.
[0033] Both ends of the base plate 1 are provided with assembly holes 14, and assembly pins are provided in the assembly holes 14. The assembly pins are fixed to the limiting plate 12.
[0034] A buffer block 13 is provided below the upper mounting block 9; the buffer block 13 can prevent the upper mounting block 9 and the lower mounting block 11 from colliding directly, providing a final buffer guarantee, thereby protecting the vibration isolator and extending its service life.
[0035] The upper mounting block 9 and the top plate 3, and the lower mounting block 11 and the bottom plate 1 are all fixedly connected by locking bolts.
[0036] The base plate 1 has fixing holes on both sides; the fixing holes are provided to facilitate the installation of the base plate 1 in a preset position.
[0037] The rubber block 2 has a deformation hole in the middle, which passes through the rubber block 2 and through the coiled steel wire rope 10. The setting of the deformation hole can save the amount of rubber used in the rubber block 2, and make the rubber block 2 O-shaped, with a certain elasticity, leaving space for the deformation of the rubber block 2, and adapting to the coiled steel wire rope 10.
[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way.
