Description

Metal slide sealing viscous damper
Technical field
The utility model belongs to damping (shaking) technical field, particularly relates to a kind of metal slide sealing viscous damper.
Background technique
Viscous damper is one of high efficiency products conventional in engineering of providing fortification against earthquakes both at home and abroad, conventional viscous damper, it forms primarily of piston, guide rod, cylinder barrel and Sealing, piston relative to cylinder body at axially reciprocating, the structure of its sealing is a technology very crucial to it, and prior art many employings macromolecular material is as Sealing, the defect existing for technique has:
1. require the working life of viscous damper as " 30 ~ 50 years ", and the easy ageing failure of the Sealing of macromolecular material, often can only ensure the effective date (life-span) of about 10 years.
2. viscous damper requires it is without initial stiffness theoretically, but owing to mostly adopting macromolecular material to seal, because its material natural quality determines that the damper of this class formation has obvious initial stiffness to be inevitable.
3. viscous damper produces a large amount of heat energy in energy dissipation process, adopts macromolecular material sealing to make friction aggravate temperature and promptly rises, have impact on normal use and the life-span of product.
Summary of the invention
The utility model provides a kind of good airproof performance metal slide to seal viscous damper, and its performance and working life are greatly improved.
In order to overcome above-mentioned shortcoming, the technical solution adopted in the utility model is such:
A kind of metal slide sealing viscous damper, comprise cylinder barrel, the secondary cylinder be connected with one end of cylinder barrel, the guide rod be arranged in cylinder barrel, be fixed on the piston on guide rod and be positioned at cylinder barrel and be arranged at the guide sleeve of piston both sides, the guide sleeve of both sides and cylinder barrel and form damper housing, described damper housing is separated into the first damping chamber and the second damping chamber by described piston, two damping cavity indoor are full of resisting medium, described piston are at least arranged the damp channel that is communicated with two damping chambers; The two ends of described guide rod are each passed through the guide sleeve of both sides, and one end is stretched out outside cylinder barrel, and the other end stretches in secondary cylinder, and piston relatively can carry out axial motion by cylinder barrel under guide rod drives; Described metal slide sealing viscous damper also comprises the piston sliding sleeve be arranged between piston and inner wall of cylinder and the axle sleeve be arranged between guide sleeve and guide rod, and described piston sliding sleeve and axle sleeve all adopt Cu alloy material to make.
In order to increase the wear resistance of piston sliding sleeve better, the surface that piston sliding sleeve contacts with inner wall of cylinder is provided with the wearing layer with graphite sintering.
Described piston is fixed on guide rod by the cooperation of semi-cyclic linkage and pressing plate.
The utility model has the benefit in following tripartite face:
1. adopt the resiliently deformable of the piston sliding sleeve made of Cu alloy material and sleeve sealing higher molecular seal much smaller, its fit system also changes into Spielpassung from traditional direct contact seal, substantially can realize the requirement of viscous damper without initial stiffness.
2. adopt Cu alloy material to make piston sliding sleeve and sleeve sealing reduce and improve because of fricative heat, viscous damper is worked for a long time, effectively, normally, performance power consumption effect.
3, adopt high strength copper alloy material piston sliding sleeve and axle sleeve, be soaked among resisting medium, not easily ageing failure, extend the working life of viscous damper, meet the usage requirement that viscous damper 50 years is non-maintaining.
In addition, because the component of metal slide sealing viscous damper because being subject to the effect of very large pressure in work process, general employing high-quality steel manufacture, the metal slide sealing piston sliding sleeve of viscous damper and its structure of molecule of Material selec-tion of axle sleeve are different from the copper alloy metallic material of the structure of molecule of steel, after overcoming friction and Extrusion, blending destroys, and having again certain resiliently deformable maintains its sealability simultaneously.
The utility model structure is simple, easy to process, stable performance, well the shake that earthquake produces can be converted into heat energy, thus reach the object absorbing outside energy, therefore can be widely used in the occasion of damping, buffering, power consumption.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, be further described embodiment of the present utility model, following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, a kind of metal slide sealing viscous damper, comprise cylinder barrel 1, the secondary cylinder 6 be connected with one end of cylinder barrel 1, the guide rod 5 be arranged in cylinder barrel 1, be fixed on the piston 2 on guide rod and be positioned at cylinder barrel and be arranged at the guide sleeve 7 of piston both sides, the guide sleeve 7 of both sides and cylinder barrel 1 and form damper housing, described damper housing is separated into the first damping chamber and the second damping chamber by described piston 2, two damping cavity indoor are full of resisting medium 4, described piston are at least arranged the damp channel 3 that is communicated with two damping chambers; The two ends of described guide rod 5 are each passed through the guide sleeve 7 of both sides, and one end is stretched out outside cylinder barrel 1, and the other end stretches in secondary cylinder 6, and piston 2 relatively can carry out axial motion by cylinder barrel 1 under guide rod 5 drives; In order to realize sealing better, prevent the resisting medium of damping cavity indoor from leaking, arrange piston sliding sleeve 8, arrange axle sleeve 9 between guide sleeve 7 and guide rod 5 between the inwall of piston 2 and cylinder barrel 1, described piston sliding sleeve 8 and axle sleeve 9 all adopt Cu alloy material to make.
When the dynamic generation of exterior object shake (shaking), the guide rod be connected with exterior object drives the piston on it to move reciprocatingly in the airtight damper housing of cylinder barrel, the resisting medium being enclosed within damping cavity indoor, pressurized side is squeezed, pressure raises, and the volume of non-pressurized side damping chamber increases, pressure is caused to reduce, thus force resisting medium to flow to non-pressurized side damping chamber from pressurized side damp channel, produce damping force, the direction of damping force is contrary with the moving direction of piston rod, thus make vibrational energy be converted into heat energy rapidly and discharge, reach the object of energy-dissipating and shock-absorbing (shaking).
In order to increase the wear resistance of piston sliding sleeve 9 better, the surface that piston sliding sleeve 9 contacts with cylinder barrel 1 inwall is provided with the wearing layer with graphite sintering.
In the present embodiment, piston 2 is fixed on guide rod 5 by the cooperation of semi-cyclic linkage 11 and pressing plate 10.
Be connected with exterior object in order to more convenient, metal slide sealing viscous damper two ends arrange a connecting lug 12, connecting lug respectively and are connected with one end that guide rod stretches out cylinder barrel, and another connecting lug is connected with the outer end of secondary cylinder.
Above mode of execution is only for illustration of the utility model; and be not limitation of the utility model; the those of ordinary skill of relevant technical field; when not departing from spirit and scope of the present utility model; can also make a variety of changes and modification, therefore all equivalent technological schemes also belong to protection category of the present utility model.
