Description
Technical field
It the utility model is related to absorber technical field, more particularly to a kind of support type damper.
Background technology
As metal damper is using increasingly extensive, more users require that damper has sealing.But because damper works
When, it is necessary to vibration displacement space transmit, decay vibration source displacement, while also to ensure under the conditions of larger movement velocity have compare
Good sealing effect, therefore the sealing of support type damper is always relatively difficult.Current existing sealing structure is poly- four
Vinyl fluoride, is made into flake structure and is sealed, but this structure is influenced greatly by material property, and elasticity modulus is low, vibration
When, material easily deforms, and produces larger gap between structure, after vibrating for a long time, almost without dynamic sealing effect, this
It is originally all-metal material that outer support type metal rubber shock absorber, which is,, then can be to damper as there is nonmetallic materials in fruit structure
Ambient adaptability has considerable influence, and preventing former damper, this is also support type from applying well in the adverse circumstances such as acid, alkali
Damper is limited always, it is impossible to the reason for applying in a big way.
Existing support type damper as shown in Figure 1 includes shell body 1, cushion blocking 2, cushion blocking 4 and center pillar 3.3 He of center pillar
Shell body 1 is connected by dampening apparatus and installation fixing end respectively, and relative motion is formed both during work.Center pillar 3 is subtracted by compression
Shake pad 2 and cushion blocking 4 transmits the force to cushion blocking 2 and cushion blocking 4, cushion blocking 2 and cushion blocking 4 occur elasticity under power effect and become
Shape, while utilize itself braking absorption vibrational energy.To ensure damper normal work, with center pillar 3 opposite transport occurs for shell body 1
, it is necessary to leave moving displacement space when dynamic, since cushion blocking is made of metal-rubber, metal-rubber is a kind of loose porous
Feature damping material, its structure is by coiling, is stretched, braiding, prepared by the technique such as compression molding, by process above into
The metal-rubber of type, is presented intermeshing macromolecular pore structure between its wire.During vibration, elasticity occurs for metal-rubber
Deformation, the mutual friction of wire phase provides damping, therefore metal-rubber is the core element of metal damper, but with metal-rubber
Service life increase, the abrasion between silk and silk is increasingly violent, super Design cooling load or it is super using magnitude application conditions under,
Metal-rubber can fall silk either excessive wear produces iron filings and these foreign matters drop in circuit board at this time or other are conductive
In metal structure, it is easy to cause serious consequence.Wire abrasion can occur fifth wheel, the fifth wheel such as fracture of wire or generation iron filings and lead to
Cross to shake dynamic friction is constantly in moving displacement aggregation in space.And the oscillation space close to middle column length end endface position opens,
Under certain condition, foreign matter can drop outside damper.

Further, the center of sleeved part 101 is equipped with overlap aperture, and the diameter of overlap aperture is equal to the diameter of center pillar 7, Jin Er
In vibration processes, cap 10 of turning back is moved together with center pillar 7 realizes effectiveness in vibration suppression.
Further, the outside diameter of sleeved part 101 is less than the diameter of mounting hole to form third space, in vibration processes, the
The presence in the three gaps cap 10 that allows to turn back is moved with center pillar 7, plays good effectiveness in vibration suppression.
Further, the outside diameter of sealing 102 is more than the internal diameter of sealing ring 9, less than the outside diameter of sealing ring 9.Further,
The outside diameter of sealing ring 9 is M1, and the internal diameter of sealing ring 9 is M2, and the outside diameter of sealing 102 is N1, and the aperture of overlap aperture is N2, M1-
M2 ＜ N1-N2, M1 ＜ 2N1-M2.So, sealing 102, will not be de- with sealing ring 9 when being moved to maximum displacement
From, avoid the first cushion blocking 6 and the second cushion blocking 8 because abrasion produce chip drop out.
Further, center pillar 7 is inserted between the first end of one end in accommodating space and housing 5 there are the 4th gap,
Realize the axial displacement at middle part.
Sealing ring 9, the surface roughness for cap 10 of turning back are 3.2, the dimensional fits of 9 outside diameter of sealing ring and 5 internal diameter of housing
Tolerance+0.03mm~+0.08mm；Overlap aperture and 7 fit tolerance+0.01mm of center pillar~+0.04mm.
In conclusion a kind of support type damper that the utility model embodiment provides, since the outer wall of sealing ring is close to
On the second cushion blocking, sealing ring structure in vibration processes does not produce radial displacement, belongs to the static structure in friction pair.Folding
The inner wall for returning cap is fitted on center pillar, and there are third space between outer wall and the inner wall of housing, cap of turning back carries out together with center pillar
Move back and forth, belong to dynamic structure in damper vibration processes.The friction pair of two structure compositions can produce axis in vibration
Moved to radial direction both direction.During generation radial displacement, cap of turning back movement, when radially maximum displacement occurs for shade of turning back,
Two structure internal volumes are still sealing.During generation axial displacement, cap of turning back compresses cushion blocking together with sealing ring, this
When sealing ring and the sealing ring internal volume of cap equivalent piston of turning back sealed.Avoid the first cushion blocking and the second cushion blocking
Because the chip that abrasion produces drops.The support type metal damper ensures the good environment applicability of all-metal damper, sealing
Well, the sealing problem of existing support type damper under vibrating conditions is solved, in axially and radially long-time vibration condition
Under all no foreign matter leak out, while sealing structure nor affects on the effectiveness in vibration suppression of damper.
