Description

A kind of spring damper

Technical field

The utility model discloses a kind of amortisseur, refer more particularly to a kind of spring damper。

Background technology

Concussion when amortisseur rebounds after being mainly used to suppress spring shock-absorbing and the impact from road surface。Through uneven road surface, although shock-absorbing spring can filter the vibrations on road surface, but spring self also has reciprocating motion, and amortisseur is just used to suppress this spring to jump。Amortisseur is too soft, vehicle body will vertical bounce, amortisseur can bring about too big resistance too firmly, hinders spring normal operation。It is mainly used in the impact from vibration of main frame, subsidiary engine, various dynamic power machine and instrument and meter, plays and reduce vibration, noise and prevent the effect impacted。Owing to there is the existing picture of self-vibration in existing amortisseur, frequency vibration in empty easily transmission, critical damping ratio generally only has 0.005, therefore poor for the isolating technique ability near resonant frequency；Noise is big, and structure is complicated, and damping effect is poor, and installing/dismounting is complicated, the problems such as the life-span is short。

Utility model content

It is big that the technical problems to be solved in the utility model there is provided a kind of internal friction, good damping effect, is conducive to crossing resonance region, decay dither and noise, simple in construction, and damping effect is excellent, and quality is little, and installation and removal are convenient, the spring damper of life-span length。

In order to solve above-mentioned technical problem, this utility model provides a kind of spring damper, it is characterised in that: include upper casing, spring, fixed metal plate, nut, fixed bolt hole, base and damped rubber ring；The described fixed metal plate left and right sides is provided with fixed bolt hole, and fixed metal plate is provided with damped rubber ring, and damped rubber ring is provided with base；Described upper casing is covered on base, and upper casing is fixed by nut and base and tightly；It is provided with spring in described upper casing。

As further improvement of the utility model, described fixed metal plate has lower rubber sound insulation friction pad。

As further improvement of the utility model, described damped rubber ring is provided with lower rubber blanket。

As further improvement of the utility model, described upper casing is provided with rubber blanket。

As further improvement of the utility model, described upper rubber blanket is provided with rubber sound insulation friction pad。

Adopting said structure, it has the beneficial effects that: this utility model adopts rubber as material, and internal friction is big, good damping effect, being conducive to crossing resonance region, decay dither and noise, simple in construction, damping effect is excellent, the plurality of advantages such as quality is little, and installation and removal are convenient, life-span length。

Accompanying drawing explanation

Fig. 1 is the structural representation of a kind of spring damper of this utility model。

In figure: 1-upper casing, 2-spring, 3-fixed metal plate, rubber sound insulation friction pad under 4-, 5-nut, the upper rubber sound insulation friction pad of 6-, the upper rubber blanket of 7-, rubber blanket under 8-, 9-fixed bolt hole, 10-base, 11-damped rubber ring。

Detailed description of the invention

Below in conjunction with drawings and Examples, this utility model is further explained explanation。

As it is shown in figure 1, a kind of spring damper, it is characterised in that: include upper casing 1, spring 2, fixed metal plate 3, nut 5, fixed bolt hole 9, base 10 and damped rubber ring 11；Described fixed metal plate 3 left and right sides is provided with fixed bolt hole 9, and fixed metal plate 3 is provided with damped rubber ring 11, and damped rubber ring 11 is provided with base 10；Described upper casing 1 is covered on base 10, and upper casing 1 is fixing with base 10 and tight by nut 5；It is provided with spring 2 in described upper casing 1；Described fixed metal plate 3 has lower rubber sound insulation friction pad 4；Described damped rubber ring 11 is provided with lower rubber blanket 8；Described upper casing 1 is provided with rubber blanket 7；Described upper rubber blanket 7 is provided with rubber sound insulation friction pad 6。

This utility model adopts rubber as material, the feature of rubber is that existing elastomeric state has again high sticky stage, the elasticity of rubber is to be liked that the change that you cross produces by its coiled molecule conformation, between rubber molecule, interaction can hinder the motion of strand, show stickiness feature, so that stress and strain is often in unbalanced state。This curling long-chain molecule structure of rubber and the more weak secondary power of intermolecular existence so that elastomeric material presents the viscoelasticity energy of uniqueness, thus has good damping, sound insulation and shock-absorbing capacity。

This utility model internal friction is big, good damping effect, is conducive to crossing resonance region, decay dither and noise, simple in construction, the plurality of advantages such as damping effect is excellent, and quality is little, and installation and removal are convenient, life-span length。

The similar amortisseur designed by technical characteristic of any employing and this utility model will fall within protection domain of the present utility model。
