Description
Technical field
The present invention relates to a kind of mechanical part device, be specifically related to the square high-mechanic pneumatic spring that a kind of naval vessel is used.
Background technique
Vibration and noise is ubiquitous in nature, life, has brought many difficult problems to people.In order to improve the Security of equipment, human lives's travelling comfort, numerous vibration and noise reducing elements are employed.Damping element commonly used has rubber vibration isolator, metal vibration isolator, pneumatic vibration damper.Pneumatic spring is a kind of important vibration and noise reducing product, because its natural frequency is low, rigidity is non-linear etc. plurality of advantages, in automobile, rail truck, naval vessel, aviation and all kinds of machinery is medium is used widely.
At present both at home and abroad pneumatic spring is broadly divided into capsule formula and two types of membrane types, and mostly air bag is circle.For some application occasion, such as the naval vessel, because the installation air size of vibration and noise reducing element receives strict restriction, existing circular pneumatic spring then can not the maximum use space, improves effect of vibration and noise reduction.Simultaneously, because the restriction in space, must improve the pneumatic spring internal pressure improving its bearing capacity, and the existing common working pressure of pneumatic spring is applied in and depresses in the height usually less than 0.7MPa, its reliability must be under suspicion.
Through preliminary search, find that application number is that 200710051635.4 Chinese invention patent discloses a kind of high-pressure large load air spring, relates to a kind of pressurized air that is higher than 1MPA with pressure as elastomeric vibration isolator.This pneumatic spring is made up of rubber utricule, cover plate, dish-shaped flange, seal ring, capsule inner stuffing.Carrying when the adjustable solidating of dish flange has frequency and improves pneumatic spring large deformation situation.The aramid fiber framework layer of utricule is sulfided into three flange integrative type structures around back being compressed by outward flange and supported flange of a circle on spacer flanger, the sulfuration glue-line is arranged inside and outside the aramid fiber framework layer.Seal by the sealing strip on the utricule, O-ring seals and teflin ring between rubber utricule and the cover plate.The packing that is equipped with on the cover plate in the rubber utricule, play a part six to from spacing with the adjustment natural frequency.
The shortcoming of technique scheme is: 1, adopt dish-shaped flange as seal connector; When pneumatic spring was started working, the radial tension of utricule was all born by the butterfly flange after the sulfuration, and its pressure tolerance is limited; Elongated and corrosion certainly exists hidden danger along with service time; 2, do not have garter spring on the utricule tripe face, make the bearing capacity of utricule descend greatly; 3, to account for volume too big for inner limit stoper, and do not have the device of buffer protection between the limit stoper, causes its bearing capacity to weaken, and reduce working life, and noise is big.
Therefore be necessary existing technology is improved.
Summary of the invention
, be tightly connected mode unreasonable to existing pneumatic spring geomery and structure not science cause problems such as bearing capacity is limited, the life-span is short, noise is big; It is more reasonable that the present invention has designed a kind of space utilization; Pneumatic spring internal pressure bearing capacity is better, long service life, the square pneumatic spring of the high-mechanic that noise is little.
The technological scheme that the present invention adopts is:

Further, the framework layer of said utricule is the aromatic polyamide cord framework layer.
A kind of square high-mechanic pneumatic spring; It is characterized in that; Comprise utricule, go up clasp, clasp, upper cover plate, lower cover plate, upper limit parts, lower limit parts and some links down, said utricule by utricule rubber, framework layer, go up the rim of the mouth steel ring, the rim of the mouth steel ring sulfides and forms down, is equipped with the groove that matches with the upper and lower rim of the mouth steel ring shape of said utricule on said upper cover plate and the lower cover plate; Said utricule is assemblied on the said upper and lower cover plate through said groove; The said clasp of going up is pressed on the last rim of the mouth steel ring of said utricule on the said upper cover plate, and said time clasp is pressed on the following rim of the mouth steel ring of said utricule on the said lower cover plate, is connected fastening between said upper and lower clasp and the said upper and lower cover plate through link; It is inner that said upper and lower spacing parts are positioned at said utricule; Said upper limit parts are connected on the upper cover plate through link, and said lower limit parts are connected on the said lower cover plate through link, have pore and mounting hole on the upper cover plate.
Further, said utricule tripe face is provided with tripe face steel ring, and said tripe face steel ring is through the neutral position of sulfuration attached to said utricule, or the pincers hoop is in the neutral position of said utricule.
Further, be further to improve the air bag bearing capacity, the air bag cord layer by layer number to make the 4-10 layer optional, have angle between the different cord floors.
Further, said upper and lower spacing parts are the hollow cylindrical structure, wall boring, and its end is imbedded said upper and lower cover intralamellar part respectively, is respectively equipped with scapulet near the end, and said scapulet outwards props up said utricule, makes total more fastening.
Further, sulfuration has one deck rubber on the surface of contact of said upper and lower spacing parts.
Further; Fit system between said clasp and the said cover plate is concavo-convex cooperation; Be specially the surface that said clasp contacts with cover plate and be provided with boss; The relevant position is provided with groove on the surface of said cover plate, and said protruding part and said groove complement each other to form concavo-convex cooperation the between clasp and the cover plate.
Further, said upper and lower clasp adopts the thicker material of thickness to process for buckleing the two halves formula structure of taking each other; Its skirts limit air bag distortion on the one hand, the scalability performance, on the other hand; Because clasp is thicker, its bending resistance square ability is strong, during pneumatic spring work; The clasp distortion is little, and system sealing property is reliable.
The invention has the advantages that: 1, air bag of the present invention is a rectangle structure, when installing space is restricted, and when being rectangular, can effectively utilize installation, improves effectiveness in vibration suppression; 2, clasp and cover plate cooperating structure up and down can effectively reduce bolt strainedly, improve the bending resistance square ability of clasp, improve the reliability of system; 3, air bag cord framework layer adopts the aramid fiber cord fabric, and air bag tripe face clamps into steel ring simultaneously, can effectively improve the airbag body bearing capacity; 4, under the cover plate, give birth to sealing effect about the rim of the mouth is pressed in through clasp about the air bag through rim of the mouth rubber initial compression volume production about the air bag; 5, internal system limit position part surface sulfuration one deck rubber plays position-limiting action, reduces additional impact force, is interlinked to the outside in the limit position part, makes system stiffness not increase too much because of built-in snubber.The square high strength cord skeleton of the present invention pneumatic spring; Bearing capacity is strong, and rigidity property is low, and the vibration insulation and noise reduction performance is good; Has certain limit function; Structure can be adjusted according to the practice situation, can greatly utilize assembly space, can be used as the vibration and noise reducing parts of other machinery such as naval vessel of the strict restriction of assembly space.
