Description
Technical field
This utility model relates to a kind of two-way vibration absorber of metal-rubber.
Background technology
Vibration (also known as vibration) refers to the process that a state changes.Vibration can affect the serviceability of precision instrument and equipment, reduces machining accuracy and fineness, the fatigue of aggravation component and abrasion, thus shortens the service life of machine and works, and vibration is also possible to cause the large deformation of structure to destroy.In order to reduce the harm of vibration, vibroshock is widely adopted.Vibroshock (shockabsorber), major function is to absorb vibrational energy, accelerates vibration decay etc..Existing frequently-used vibroshock mainly has hydraulic buffer, inflatable vibration damper, resistance-adjustable vibroshock, double adjustable shock absorber etc..
So-called metal-rubber is the elastic cellular material of a kind of homogenizing, it is by certain process, by certain mass, stretching is opened, the tinsel of spiral status is emitted in punching press (or rolling) mould, in an orderly manner then with cold stamping method and molding.Its raw material is tinsel, has both had the characteristic that selected metal is intrinsic, has had again the elasticity as rubber, therefore hence obtain one's name.
Metal-rubber vibration absorber has the characteristic of rubber and metal simultaneously so that it is disclosure satisfy that the needs of damping vibration attenuation under high temperature, low temperature and corrosive environment, is a kind of preferably vibration absorber.But most metals rubber damping device on the market can only carry out unidirectional vibration damping, limit its application.
Utility model content
In order to solve the problems referred to above, this utility model provides a kind of two-way vibration absorber of metal-rubber, and main purpose is to improve effectiveness in vibration suppression, it is adaptable to the environment such as high temperature, humidity, and this utility model volume is little, be readily disassembled, it is possible to realize two-way vibration damping.
A kind of two-way vibration absorber of metal-rubber, including frame structure, attachment structure and metal-rubber.
Described frame structure, including base, mesochite and upper cover；Base is one with the cylinder of lower baffle plate, and base inner wall is provided with screw thread；It is provided with two bolts hole bottom described lower baffle plate, is used for fixing this vibration absorber；A through hole it is provided with bottom the lower baffle plate of base cylinder interior；Upper cover is the cylinder of a band upper spacer, and upper cover inwall is provided with screw thread, is provided with a through hole in the middle of upper spacer；Mesochite is the cylinder of an Intermediate Gray dividing plate, is provided with through hole in the middle of dividing plate, and mesochite outer wall has screw thread；The through hole of base, upper cover and mesochite is in straight line and equal diameters up and down.The screw thread of base, upper cover and mesochite is the most identical, and upper cover, mesochite and base by thread are connected in turn up and down.In frame structure, between mesochite and base, mesochite and upper cover, form upper and lower two separate space respectively；One metal-rubber of each placement in two separate space.
Described metal-rubber is the cylinder of hollow structure, and metal-rubber uses memory alloy wire to make.
Described attachment structure, including axis, hexagonal (hexagon)nut and pad；Axis lower end is mobilizable to be placed in base lower clapboard through hole but does not contacts with this through hole, and axis upper end fastens with hexagonal (hexagon)nut after metal-rubber, each through hole；Middle shaft centre line is in a straight line with each through hole center of circle；Pad is the circular sheet that centre is provided with through hole；The both ends of the surface up and down of the metal-rubber of each separate space all place a pad.
Advantage of the present utility model
1. this utility model compact conformation, volume are little, lightweight, convenient dismounting, change.
2. to have full ambient engine adaptability, storage, service life long for this utility model: high-low temperature resistant (-80 DEG C--1000 DEG C), salt spray resistance, mycete, humidity, ozone, oils and fats, vacuum, sunshine, radioprotective, dust and the corrosion of various organic solvent.
3. this utility model has two-way effectiveness in vibration suppression, can effectively reduce compression and the power of stretching.Initial stiffness is big, and substantially, hysteresis loop is full, is a outstanding energy-dissipating device in small vibration power consumption.

Detailed description of the invention
Utility model works principle is as follows:
Nowadays conventional metal-rubber many employings copper wire, aluminium wire, stainless steel silk or memory alloy wire, this utility model uses memory alloy wire to make.
This utility model includes the base of frame structure, upper cover and mesochite (base, upper cover and mesochite use essence steel to make), the axis of attachment structure, hexagonal (hexagon)nut and pad and metal-rubber.Concrete compound mode is as it is shown in figure 1, base, axis connect external member respectively.Owing to metal-rubber can only bear the pressure of central axis direction, when axis is by downward pressure, power will be acted on the pad of upper metal rubber exterior by the hexagonal (hexagon)nut engaged with axis, and act on the metal-rubber on top further, metal-rubber plays a role, and vibration absorber produces effectiveness in vibration suppression；When axis is by pulling force upwards, power can be acted on the pad outside the metal-rubber of bottom by axis, and acts on the metal-rubber of bottom further, and metal-rubber plays a role, and vibration absorber produces effectiveness in vibration suppression.There is gap between this utility model axis and base, be not directly contacted with, shell is divided into upper cover, mesochite, base, it is to avoid the directly transmission of power, add the effectiveness in vibration suppression of the two-way vibration absorber of metal-rubber.
It is demonstrated experimentally that the two-way vibration absorber of metal-rubber of this utility model design, it is possible to effective minimizing needs pressure and the pulling force produced between vibration damping instrument, successfully buffers bi-directional force, is a kind of two-way vibration absorber of metal-rubber with remarkable result.This utility model volume is little, simple in construction, remove and install conveniently, and have high temperature resistant, low temperature, corrosion-resistant, be difficult to the advantages such as aging, there is the strongest practicality and development prospect.
