Abstract
The invention relates to a three-direction spacing type wire-rope vibration isolator which is used for the vibration isolation of various electromechanical apparatuses and facilities in the fields of ships, vehicles, aviation, buildings and the like. A three-direction elastic spacing mechanism is arranged between upper and lower bearing splints of the wire-rope vibration isolator and is composed of a rigid rod and a spacing seat ring, wherein different spacing clearances are designed between the rigid rod and a rubber layer compounded in an inner cavity of the spacing seat ring according to spacing requirements. When the wire-rope vibration isolator bears vibration or impact in any direction, once a dynamic displacement exceeds the designed spacing clearance valve, the rigid rod is in contact with the rubber layer compounded in the inner cavity of the spacing seat ring, so that the upper and lower bearing splints of the wire-rope vibration isolator are prevented from being further and mutually dislocated in the direction, thereby achieving the purpose of elastic spacing. Thus, the excellent softened nonlinear rigidity and damping characteristic of the wire-rope vibration isolator are kept, and the restriction requirements for displacements in three directions in engineering can be met. The wire-rope vibration isolator provided by the invention has a compact structure and reliable performance.

Technical field
The present invention relates to a kind of three-dimensional spacing-type steel-wire isolator, be used for the vibration isolation of all kinds of electromechanical equipments in field such as boats and ships, vehicle, aviation, building, facility.
Background technique
At present; comprise that the Realization of Products such as each field of boats and ships, carrier vehicle, space flight and aviation and engineering construction general employing all types of vibration isolation (damping) device such as rubber-type vibration damper, steel-wire isolator, pneumatic spring carry out the transmission of vibration isolation, slow (resisting) punching and reduction construct noise to electromechanical equipment, facility, reach protection equipment, installation security and the normal purpose of moving.Especially the steel-wire isolator that has multidirectional softening type non-linear rigidity and damping characteristic is used widely.
The max structure characteristics of existing steel-wire isolator are to have multidirectional large displacement resiliently deformable function, and maximum dynamic deformation can be up to more than the 100mm.Although this dynamic deformation function is conducive to resist the large impact distortion and reduces shock response, but be unallowed for some special operation condition, as wish vibration isolator in certain direction or simultaneously on three directions in space, can control this resiliently deformable in certain scope, otherwise may cause installing generation rigid collision accident between the equipment of steel-wire isolator and the adjacent miscellaneous equipment.Therefore, a kind of steel-wire isolator with three-dimensional different distortion spatial constraints ability of design has become the demand in market.
Summary of the invention
The object of the invention is to solve the spacing capability problems of existing steel-wire isolator when the three-dimensional large elastic deformation of space, adapt to the vibration isolation demand of engineering field under specific spacing requirement, the softening type non-linear rigidity and the damping characteristic that keep simultaneously steel-wire isolator, the vibration isolation effect that the realization system is good.
Main solution of the present invention is achieved in that
Basic structure of the present invention is to adopt upper and lower supporting splint or base plate to connect firmly multiply Stainless Steel Wire twisted wire to form multi-circle spiral flow or spheric annulus elastomer, after the assembling of some screws, consist of steel-wire isolator again, and a kind of three-dimensional elastic spacing mechanism is set in the upper and lower supporting splint of steel-wire isolator neutral position.Three-dimensional elastic spacing mechanism is made of rigid rod and spacing seat ring, is fastened on the upper and lower supporting splint or base plate of steel-wire isolator with joint bolt respectively.Rigid rod adopts aluminum alloy, stainless steel or nylon material to make, and spacing seat ring housing adopts aluminum alloy stainless steel or nylon material to make equally, and inner chamber composite rubber layer, rubber layer thickness are 2～10mm.Rigid rod is set in the spacing seat ring, consists of three-dimensional elastic spacing mechanism.Be designed with different spacing gaps between the rubber layer of rigid rod and spacing seat ring inner chamber, the spacing gap of this three-dimensional can be designed respectively between 0.5～10mm, is determined by the spacing requirement of reality.The shape of spacing seat ring inner chamber, size design according to the requirement of the different spacing amounts of three-dimensional.The purpose of spacing seat ring inner chamber composite rubber layer is to avoid rigid rod to produce rigid collision with spacing seat ring housing in vibration or impact process, reduces vibration or shock response.When steel-wire isolator bears the vibration of either direction or impacts, in case dynamic displacement has surpassed the spacing gap value of design, rigid rod contacts with the compound rubber layer of spacing seat ring inner chamber, stop flexibly the upper and lower supporting splint of steel-wire isolator upwards to continue the mutual changing of the relative positions the party, thereby realized the purpose of elastic spacing.
The present invention compared with prior art has the following advantages:
The present invention is applicable under the vibratory impulse environment vibration isolation slow (resist) punching of equipment that the flexible displacement restriction of either direction is required, can avoid between the vibrating isolation system equipment because of generation rigid collision phenomenon damage equipment.Both keep steel-wire isolator good softening type non-linear rigidity and damping characteristic, realized good vibration isolating effect, can satisfy again the displacement restriction requirement on three directions required in the engineering, compact structure, reliable performance.
