Compared with the prior art, the viscous damper has the advantages of simple structure, small size, large energy, good application effect, stable performance, long service life, etc.
Description
Technical field
The utility model relates to buffer device, relates in particular to a kind of viscous damper.
Background technique
Buffer is a kind of application machinery very widely, can be used for fields such as machinery, large-scale construction engineering, important building, railway transport, is used for alleviating and the impact of bearing outer year.Damper is a kind of in the buffer device, and it mainly is to utilize damping material to absorb the energy that the external world passes over, yet, there is following defective in present employed damper: 1, cushioning effect is poor, shock duration is long, and recoil force is big, has the shock oscillation phenomenon; 2, volume is big, is unfavorable for the use of narrow and small occasion; 3, energy dissipating poor performance.
Summary of the invention
The purpose of this utility model be exactly provide in order to overcome the defective that above-mentioned prior art exists that a kind of bearer cap is big, the viscous damper of good buffer effect, compact structure.
The purpose of this utility model can be achieved through the following technical solutions; Viscous damper, it is characterized in that, comprise cylinder body, piston, piston rod, damping material chamber, sealed end cover, seal ring, described cylinder body adopts rigid material, and described piston is located in the cylinder body, described piston rod one end is connected with piston, the other end stretches out outside the cylinder body, and described damping material chamber is located in the cylinder body, has filled the high viscosity damping material in it, described sealed end is set in the end of cylinder body, and described seal ring is located at the inboard of sealed end cover.
Described cylinder body and piston are cylindrical.
Described piston external diameter is formed with a gap less than cylinder diameter between piston and the cylinder body.
Described piston two ends are equipped with piston rod, and described cylinder body two ends are equipped with sealed end cover and seal ring, and described piston can be reciprocating in the damping material chamber.
Described cylinder body peripheral hardware retaining thread.
Compared with prior art, the utlity model has following characteristics:
1, owing to adopt the damping material of high stability, product can be used in the ambient temperature range of broad;
2, the moving element of product has only piston rod, and it is to move under the good air-proof condition of maintenance, need not maintenance so the utility model can use for a long time;
3, change damping material kind, characteristic or mechanical realization, can manufacture and design performance difference, the different product of applicable situation;
4, compare with the same specification other products, the utlity model has volume little, can hold big, outstanding features such as damping is good, simple installation.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of viscous damper comprises cylinder body 1, piston 2, piston rod 3, damping material chamber 4, sealed end cover 5, seal ring 6; Described cylinder body 1 is cylindrical, it adopts rigid material, described piston 2 is located in the cylinder body 1, described piston rod 3 one ends are connected with piston 2, the other end stretches out outside the cylinder body 1, and described piston 2 two ends are equipped with piston rod 3, described piston 2 external diameters are slightly less than cylinder body 1 internal diameter, make between piston 2 and the cylinder body 1 to be formed with certain interval 7, described damping material chamber 4 is located in the cylinder body 1, has filled high viscosity damping material 41 in it, described piston 2 can be reciprocating in damping material chamber 4, described sealed end cover 5 is located at the two ends of cylinder body 1, and described seal ring 6 is located at the inboard of sealed end cover 5, and described cylinder body 1 peripheral hardware is useful on fixing screw thread 11.
Adopt filling apparatus that damping material 41 is full of in the cylinder body 1, carry when impacting outside piston rod 3 is subjected to, the damping material 41 that is enclosed within the cylinder body 1 will be squeezed, and produce pressure, make piston 2 be subjected to reaction force; Simultaneously, compressed damping material 41 from the gap 7 of cylinder body 1 and piston 2 by the time can produce surface friction drag to piston 2; Along with damping material 41 is continued compression, these two power constantly increase, and striking velocity reduces gradually.Can adjust the size of reaction force, surface friction drag according to the difference of use occasion.
Because this effect has prolonged the outer extinction time that carries impact, thereby reduced the outer dynamic impulse force that carries.In compression process, an outer impact kinetic energy part of carrying is converted into heat energy and is melt in the air, and a part of damped material 41 absorbs.Because damping material 41 has higher viscosity, is equipped with special construction of the present utility model, very steady when making the utility model work, do not beat, have higher utilization efficiency.
