Embodiment
Below by drawings and Examples, the present invention is further elaborated.
As shown in Figures 1 to 5: a kind of vibration damper, top gland 1, middle part elastomer 2 and bottom support seat 3 is comprised.Middle part elastomer 2 is arranged on bottom support seat 3, and top gland 1 is suppressed on middle part elastomer 2.Top gland 1 treats the equipment of damping for carrying, middle part elastomer 2 is the core component of vibration damper, plays buffer function.Bottom support seat 3 fixes on the ground, as the pedestal of whole vibration damper.Middle part elastomer 2 comprises the press spring base 21 be made up of rubber.Be provided with some stage clips 22 in press spring base 21, stage clip 22 runs through the thickness direction of press spring base 21 and the two ends of stage clip 22 protrude from the upper and lower end face of press spring base 21 respectively.The upper and lower end face of all stage clips 22 all flushes.Stage clip 22 is coated with rubber layer 4, and press spring base 21 is one-body molded by injection mould with rubber layer 4.The above stage clip 22 is coated with rubber layer 4 and specifically refers to: the outer wall of stage clip 22, inwall and two end part are all coated with rubber, and all rubber is all connected, and whole stage clip 22 is coated in rubber completely.
Even in order to ensure that top gland 1 each point is subject to coming from the support force of stage clip 22, in the present embodiment, stage clip 22 is uniformly distributed along the length direction of press spring base 21 and width direction.Meanwhile, in order to save raw material under the prerequisite ensureing middle part elastomer 2 intensity and damping effect, it is 1 millimeter by the Thickness Design of rubber layer 4.Certain the present invention does not do concrete restriction to the thickness of rubber layer 4, and in other embodiment, the thickness of rubber layer 4 can between 0.8 ~ 1.2 millimeter
.
Bottom support seat 3 is made up of rubber substrate 31 and metallic support lid 32, and metallic support lid 32 is fastened on rubber substrate 31.Rubber substrate 31 has good buffer function, and that is bottom support seat 3 can play the effect of secondary shock-absorbing, so can further improve damping effect.
The position that the upper-end surface of rubber substrate 31 is corresponding with middle part elastomer 2 offers multiple blind hole 12.The existence of blind hole 12 can play the effect of noise reduction, noise reduction, can play certain buffer function again simultaneously, and structure is simple, practical.The upper-end surface of metallic support lid 32 is provided with the locating slot 5 that shape, size and press spring base 21 matches, and press spring base 21 is arranged in locating slot 5.In the present embodiment, press spring base 21 is square structure, and the locating slot 5 matched also is square structure.Locating slot 5 can play the effect of location to press spring base 21, avoid it occur when up-down vibration to offset and affect the stability of whole vibration damper.In addition, the bottom of rubber substrate 31 is covered with the stupefied bar 6 be made up of rubber.Stupefied bar 6 can play anti-skidding effect, can guarantee that vibration damper stably fixes on the ground, can play certain buffer function again simultaneously, can further improve damping effect.
Be provided with backing plate 8 between middle part elastomer 2 and top gland 1, the size press spring base 21 of backing plate 8 matches, and make backing plate 8 just in time can cover all stage clips 22, backing plate 8 is suppressed on stage clip 22.The gravity of equipment is evenly distributed on each stage clip 22 by this backing plate 8, makes each stage clip 22 uniform force, so can improve damping effect and working stability.
The middle part of top gland 1 is installed with nut 7, can be screwed into screw rod in nut 7, and screw rod is for connecting vibration damper and treating shock-absorption device.In the present embodiment, nut 7 is fixedly arranged on the lower end surface of top gland 1, top gland 1 position corresponding with nut 7 offers the through hole 9 passed for screw rod, the one side that backing plate 8 is relative with top gland 1 is provided with the hemispherical projections 10 that size and nut 7 match, and nut 7 is suppressed in hemispherical projections 10.Design like this, nut 7 tightly can not play and connect vibration damper and the effect treating shock-absorption device, can coordinate again with hemispherical projections 10 simultaneously, backing plate 8 is played to the effect of location, avoid it operationally occur to offset and affect the stability of whole vibration damper, structure is simple, practical.
In addition, top gland 1, middle part elastomer 2 and bottom support seat 3, are tightened together as fastening piece 11 by some bolts by vibration damper of the present invention successively.The two ends, left and right of bottom support seat 3 are respectively arranged with fastener slot 13, coordinate and whole vibration damper can be fixed on corresponding ground with fastening piece in fastener slot 13.
The stage clip 22 of the middle part elastomer 2 as core component in vibration damper of the present invention is coated in rubber completely, and whole vibration damper height is low, and center of gravity is low, and stability is high; Under identical damping intensity, vibration deformation is less, is specially adapted to the equipment that Oscillation Amplitude is unsuitable excessive, such as Central air-conditioning unit, highly versatile; Simultaneously, in cushion technique field, the damping effect that stage clip 22 plays is positive damping, the damping effect that rubber plays is passive damping, when stage clip 22 be coated on completely combine together with rubber in rubber time, the resonance that stage clip 22 causes and the resonance that rubber causes will be cancelled out each other, thus thoroughly avoid the generation of resonance, support equipment stable operation.
The above is enlightenment according to embodiment, and by above-mentioned description, relevant staff in the scope not departing from this invention thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on specification, must determine its scope protected according to right.
