Abstract

The utility model discloses a resonance peak resistant shock absorber capable of avoiding resonance peak, which overcomes the defects of the prior shock absorber such as small damp and high resonance magnification times, and can realize large damp in resonance and small damp in shock absorption. Therefore, no obvious resonance peak exists in shocking process. Electronic equipment as well as various instruments and meters are insulated from shock well. The utility model includes a cover cap (2) inside a bowl-shaped frame (4), a connecting nut (1), a spring (3) sleeved on an upper gasket (13), a damping gauze pad (5), a lower gasket (6), an expansion ring (12) and a cushion plate (7). A support top sleeve (8) is used for connection with a bottom plate (9), a lower gauze pad (11) is arranged on a bottom plate (9), and the bottom plate (9) is connected with the bowl-shaped frame (4) through hollow rivets (10).

Description

Keep away harmonic shock peak vibration damper
Technical field
The utility model relates to a kind of degree vibration dampers of keeping away except that the harmonic shock peak such as metal three-dimensional.
Background technique
Various electronic equipments, instrument, instrument mostly are rubber absorbers or rubber-metal vibration damper greatly with vibration damper in the prior art, and there is common deficiency in the metal vibration damper of minority owing to be subjected to structure and raw-material restriction.The damping of itself is little, the natural frequency height, and the harmonic shock magnification factor is big, and damping effect is undesirable, does not satisfy the shock insulation requirement of high precision apparatus.
The model utility content
The utility model has remedied vibration damper defective of the prior art, and a kind of vibration damper of no harmonic shock peak value simple in structure is provided.Its assembly all is a Structural Hardware, adapts to various operating conditions and rugged environment better.Main damper element metal spring, attaching nut realize axial damping requirement, the damping requirement of block, damping twine, the damping gasket interaction realization warp-wise between them.When by humorous earthquake region, because harmonic shock produces bigger amplitude of vibration, at this moment attaching nut, block, damping twine, the work of damping gasket fellowship interact between them and produce bigger frictional damping, have suppressed the harmonic shock peak value.When by humorous earthquake region, have only attaching nut and spring work, damping is very little, and damping effect is preferably arranged.
The beneficial effects of the utility model are: 1. do not have the harmonic shock peak value, make by the damping thing 2. good damping performances that preserve from.The vibration absorber damping is very little, thus the whole damping effect that added.3. all metal construction satisfies the usage requirement of rugged environment better.
Description of drawings
Fig. 1 is that master of the present utility model looks sectional structure chart.
Fig. 2 is the scheme of installation of overlooking of the present utility model.
Among Fig. 1: 1. 8. supports of attaching nut's 2. block 3. spring 4. bowl-shape frames, 5. damping gauze pad 6. lower levelling plates, 7. buffer substrate tablets overlap 9. base plates, 10. tubular-shank rivets, 11. buffering gauze pads, 12. packings, 13. Upper gaskets
Embodiment: 1 pair of model utility of following structural drawing is described further.Referring to Fig. 1, the utility model vibration damper axially be that combination by block of the attaching nut (1) in the bowl-shape frame (4) (2) and spring (3) realizes, when vibration damper bears when contracting load, the bottom that is equipped in the spring (3) in the block (2) is coupled together fixing by base plate.Wherein cushion pad (11), base plate (9) and bowl-shape frame (4) couple together with tubular-shank rivet (10).The other end links to each other with attaching nut (1), and attaching nut (1) is assemblied on the block (2).When amplitude of vibration is very little, attaching nut (1) is shaken with spring (3), when amplitude of vibration was big, attaching nut (1) was depressed with (2) motion of blocking a shot, and propped up support cover (8) simultaneously, withstood the combination of damping gauze pad (5) and buffer substrate tablet (7), lower levelling plate (13), (6).Packing (12) in block (2) and damping gauze pad (5) lower levelling plate (13) damping net (5) is because stressed, and the bigger frictional damping of generation each other suppresses the harmonic shock peak.Big damping when forming a harmonic shock like this, the shock mitigation system of little damping during damping is finished the isolation of vibrations.
When the warp-wise of vibration damper is stressed, the system that block (2), Upper gasket (13), damping gauze pad (5), reinforcement packing (12), lower levelling plate (6) are formed.Between them mutually motion form the elastic system that damping is arranged, its rigidity and axial rigidity approximately equal, thus realized the vibration isolation of warp-wise.

Claims (1)

  1. The utility model is a kind of vibration damper that does not have the harmonic shock peak value, form by metal spring, damping spring, shell, it is characterized in that the attaching nut (1) in the bowl-shape frame (4), the axial damping spring of metal spring (3) composition and the damping spring that block (2), damping gauze pad (5) and damping gasket (13), (6) are formed, with support cover (a 8) jack-up, base plate (9) is formed by connecting with tubular-shank rivet with bowl-shape frame (4).
