Description
Technical field
The present invention relates to a kind of vibration isolation buffering device of equipment, specifically is a kind of complex spring damp adjustable vibration isolator.
Background technique
Existing wire gaze three-dimensional vibration isolator structure as shown in Figure 1, such vibration isolator is gone up wire gauze pad 3, a shell 4, a following wire gauze pad 5, a spiral spring 6, a base plate 7 and four tubular-shank rivets 8 and is formed by a coupling shaft 1, catch 2, one.During installation, coupling shaft 1 by screw with linked to each other by device for vibration insutation, mounting screw links to each other with the basis in the tubular-shank rivet 8.The axial rigidity of vibration isolator is composed in parallel by last wire gauze pad 3, following wire gauze pad 5 and spiral spring 6, and radial rigidity is only provided by last wire gauze pad 3, and damping is mainly provided by the wire gauze pad.Have following defective in actual use: the axial rigidity of vibration isolator causes three axial anti-vibration and shock performance differences of vibration isolator very big much larger than radial rigidity, has greatly limited the using scope of vibration isolator; The damping that the wire gauze pad provides is very little and uncontrollable, can not carry out independent setting according to the residing vibration environment of equipment, causes the not good and unstable properties of vibration isolating effect of vibration isolator.
Summary of the invention
Existing such vibration isolator vibration isolating effect is not good in order to overcome, unstable properties and the little deficiency of using scope, the invention provides a kind of complex spring damp adjustable vibration isolator, the very little and damping of three axial anti-vibration performance difference of this vibration isolator can be adjusted separately, improve vibration isolating effect and stability, enlarged the using scope of vibration isolator.
The shell that has opening on the present invention includes, base plate is equipped with in the below of shell, be provided with coupling shaft in the shell, the opening of shell is stretched out in the upper end of coupling shaft, it is characterized in that: described coupling shaft middle part is provided with the shaft shoulder, between shaft shoulder upper surface and the shell roof from down and on be equipped with successively first belleville spring, on wire gauze pad and catch, the upper surface of catch and the applying of the roof of shell; Between the shaft shoulder lower surface and base plate of coupling shaft, second belleville spring and following wire gauze pad are housed from top to down successively, rebasing of following wire gaze and base plate are fitted; The coupling shaft lower end has endoporus, and the spiral spring is housed in the endoporus.
Further improve, the shaft shoulder bottom of coupling shaft also is provided with adjustable damping mechanism, comprise folding ring, tapered collar and Adjusting bolt Adjusting screw, the upper-end surface of described folding ring and coupling shaft shaft shoulder lower surface are fitted, the inwall of cylindrical and shell is close to, the circular cone cylindrical of tapered collar and the internal taper hole of folding ring are fitted, and the upper-end surface is lower than the upper-end surface of folding ring, and its lower end surface exceeds the lower end surface of folding ring and fit with the upper-end surface of Adjusting bolt Adjusting screw.Adjusting bolt Adjusting screw is fixed by the external thread rotary of coupling shaft lower end, and following wire gauze pad and second belleville spring are enclosed within on the step cylindrical of Adjusting bolt Adjusting screw.
Further improve, between the external diameter of spiral spring and coupling shaft hole wall, lining is housed.
Further improve, described shell and base plate are fixed with tubular-shank rivet.
Beneficial effect of the present invention is:
1, the radial rigidity of vibration isolator is provided jointly by the radial rigidity of last wire gauze pad and following wire gauze pad, the belleville spring because upper and lower wire gauze pad has been connected respectively, reduce axial rigidity, made the axial rigidity of vibration isolator and radial rigidity approach, enlarged the using scope of vibration isolator; And belleville spring can be to the wire gauze pad owing to the creep that thump produces compensates, and the stability that has improved vibration isolator reaches anti-by force towards ability.
2, increase adjustable damping mechanism, because damping can independently be adjusted, made vibration isolator can satisfy the damping characteristic requirement of different vibration environments.
3, increased a lining between spiral spring and coupling shaft inner hole wall, when big magnitude radial vibration and thump, protection spiral spring is not subjected to shearing force and destroys, and has improved the stability of vibration isolator.
Description of drawings

Fig. 2 is structural representation of the present invention.
Embodiment
The present invention will be further described below in conjunction with accompanying drawing.
As shown in Figure 2, complex spring damp adjustable vibration isolator comprises coupling shaft 1, catch 2, last wire gauze pad 3, shell 4, following wire gauze pad 5, spiral spring 6, base plate 7, tubular-shank rivet 8, first belleville spring 9, folding ring 10, tapered collar 11, Adjusting bolt Adjusting screw 12, lining 13, second belleville spring 14.Be equipped with successively from top to down between the shaft shoulder top of coupling shaft 1 and the shell 4 catch 2, on wire gauze pad 3 and first belleville spring 9, in the shaft shoulder bottom of coupling shaft 1 folding ring 10, tapered collar 11, Adjusting bolt Adjusting screw 12, second belleville spring 14 and following wire gauze pad 5 are housed successively from top to down, in the endoporus of coupling shaft 1 lower end spiral spring 6 is housed, between the external diameter of spiral spring 6 and coupling shaft 1 hole wall lining 13 is housed, shell 4 is fixed with base plate 7 usefulness tubular-shank rivets 8.
The damping of vibration isolator is mainly provided by dry friction, screws Adjusting bolt Adjusting screw 12, presses on the tapered collar 11 to make folding ring 10 outside spreadings by tapering, increases the frictional force between folding ring 10 cylindricals and shell 4 hole walls, and interplanar frictional force also increases simultaneously; Otherwise, unscrew Adjusting bolt Adjusting screw 12, then frictional force reduces; Be adjusted to the damping value of setting according to vibration environment repeatedly.
The axial rigidity of vibration isolator is provided by the compound rigidity of last wire gauze pad 3, first belleville spring 9, second belleville spring 14, following wire gaze 5 and spiral spring 6.
