Abstract
The utility model discloses an anti-vibration pad, comprising a lower surface provided with a prism structure, and an upper surface provided with a single-groove structure, namely, the upper and lower surfaces of the pad form an irregular body, wherein the irregular body is a trapezoidal groove or an arched groove structure, and the upper surface and the lower surface of the groove is in mutual dislocation. A set of grooves is formed in vertical direction of the lower surface groove; two sets of mutually vertical grooves on the lower surface, in an enclosure shape, form a bump which is a quadrilateral prism. Under the effect of a vertical force, four laterals of the prism mainly produce flexure deformation to reduce a horizontal acting force accompanied with compression and tensile deformation. After the acting force is unloaded, the deformation is recovered rapidly. A static stiffness of the pad can be realized by changing width, depth, inter-groove space, bottom width of the groove and modulus of the used raw material so that the pad has better comprehensive use performance.
Description
Technical field
The utility model relates to a kind of rail clip vibration attenuation pad, relates in particular to that fastener in a kind of track traffic uses, and an amount of elasticity can be provided, and has the vibration attenuation pad of better effectiveness in vibration suppression.
Background technology
Employed fastener system in track traffic, decapacitation is the rail tram fixedly, stops the vertical and horizontal displacement of rail, prevent that rail from tumbling beyond, should also provide elasticity preferably, to alleviate the vibration that produces in the wheel track running harm to sleeper, railway roadbed and surrounding building.
The elasticity of fastener system is provided by railway rail pad and iron chair lower bolster.Require this backing plate to have higher resilience, the lower quiet rigidity and the lower output ratio of Q-switching to free running are to satisfy the requirement in the actual operation.
The upper and lower faces list groove backing plate of being habitually practised at present, under the vertical force effect, groove can only produce the flexural deformations of left and right two aspects, lateral deformation is bigger, the outside lateral expansion of backing plate, contacting piece produces certain horizontal force, influences the fastener composite rigidity to a certain extent, also can influence vibration damping, the vibration isolating effect of fastener to a certain extent.
The utility model content
The purpose of this utility model is to provide a kind of novel damping backing plate, because its special structure not only makes backing plate provide high rebound degree by deflection and shearing simultaneously, also has the lower quiet rigidity and the output ratio of Q-switching to free running; And be subjected under the vertical active force at backing plate, can convert the lateral deformation of part to longitudinal strain, reduce horizontal force, to guarantee the comprehensive functional performance of fastener system, ensure train by the time supporting-point have elasticity and higher vibration and noise reducing function preferably.
In order to achieve the above object, the vibration attenuation pad that provides of the utility model adopts combined groove structure.Be that the upper and lower surface of backing plate forms irregular body.This irregular body is trapezoidal groove or arch groove structure, and groove upper and lower faces mutual dislocation.Vertical direction at the soffit groove forms one group of groove again.Two groups of orthogonal grooves of soffit surround projection, and this projection is the quadrangle terrace with edge.Under the effect of vertical force, four sides of terrace with edge mainly produce flexural deformations, simultaneously also with compression and tensile deformation.Unload masterpiece firmly after, deformation recovers rapidly.
The vibration attenuation pad that the utility model provides has solved under vertical active force, and the problem that transverse deformation is excessive laterally, vertically provides flexural deformations simultaneously, and backing plate is stressed more even.The quiet rigidity of vibration attenuation pad can realize that its characteristics are as follows by width, the degree of depth, groove pitch, the width of bottom land and the raw-material modulus of using that changes groove:
(1) the terrace with edge structure of vibration attenuation pad guarantees under vertical active force, and four aspects of terrace with edge produce deformation, reduce horizontal force, guarantee the comprehensive functional performance of fastener system.
(2) deformation recovers fast, and the output ratio of Q-switching to free running is low, good damping result.
(3) long service life has reduced the maintenance, repair workload of circuit.
(4) the inefficacy backing plate can recycling, helps environmental protection.

The specific embodiment
The raw material that the utility model adopts is the material modified or macromolecule complex material of high-performance poly copolyether ester elastomer, can buy off-the-shelf from manufacturer.The utility model just is molded into goods with above-mentioned raw materials with method time processing in mould of injection moulding.This product does not have special requirement to production equipment, and known equipment gets final product.
Please, be the front view of the utility model product referring to Fig. 1.As seen soffit is arranged on the body is square terrace with edge shape projection, and upper surface is the arch form groove structure.
Please, be the sectional drawing of the utility model product referring to Fig. 2.As seen body is the arch groove structure, and groove upper and lower faces mutual dislocation.Vertical direction at the soffit groove forms one group of groove again.Two groups of orthogonal grooves of soffit surround projection, and this projection is the quadrangle terrace with edge.By changing the width A of upper and lower surface groove, degree of depth C, groove pitch B can make the backing plate of different quiet rigidity.
Please, be another kind of product figure of the present utility model referring to Fig. 3.As seen soffit is arranged on the body is square terrace with edge shape projection, and upper surface is the ladder type groove structure.
Please, be the sectional drawing of the another kind of product of the utility model referring to Fig. 4.As seen body is the trapezoidal groove structure, and groove upper and lower faces mutual dislocation.Vertical direction at the soffit groove forms one group of groove again.Two groups of orthogonal grooves of soffit surround projection, and this projection is the quadrangle terrace with edge.By changing the width A of upper and lower surface groove, degree of depth C, groove pitch B, the width D of bottom land can be made the backing plate of different quiet rigidity.
Claims (3)
1. a vibration attenuation pad is characterized in that being formed with groove structure at the upper and lower faces of body.
2. vibration attenuation pad according to claim 1 is characterized in that the upper and lower surface of backing plate forms groove structure, and this groove structure is trapezoidal groove or arch groove structure, and groove upper and lower faces mutual dislocation.
