Abstract
The invention relates to a compression spring. A main body (1) of the compression spring is a closed ring form made of an elastic material, at least two complete waveforms (2) are arranged on the ring form, and are identical in parameter, and when the compression spring is in use, peaks and valleys of the waveforms are pressed between two parts needing elastic force respectively. The compression spring is simple in structure, low in production cost, capable of being used under the circumstances of large radial diameter and small axial mounting space, high in flexibility and wide in application range, can adapt to different using requirements through simple improving.
Description
Technical field
The present invention relates to a kind of Compress Spring.
Prior art
Spring utilizes elasticity and the self structure feature of material, produces deformation and realizes transformation of energy in when work, is usually used in buffering, vibration damping or load etc. is provided.Compression helical spring is simple in structure, and as shown in Figure 1, in mechanical system, application is very extensive.Because the elastic force of compression helical spring is curled up than (D/d) and the isoparametric impact of compression height, for some fixing mounting points, due to the restriction of mounting structure, compression helical spring cannot meet usage requirement.As some the rotation axis seal positions in aeroengine, its sealing principle is to realize by the self-lubricating function of graphite, at work, due to the continuous loss of graphite annulus of seal action, need to apply certain active force to graphite annulus, realize graphite annulus and move axially, with electrode compensation part and make graphite annulus and dynamic component fits tightly, reach efficient sealed object.As shown in Figure 2, graphite annulus 11 at work, need to arrange spring in 13 places, position between itself and shell 12 to sealing structure, guarantees that the graphite annulus 11 of continuous loss compensates.Because the axial installing space L at these 13 places, position is little, and radial dimension D1 requires greatly, if adopt conventional compression helical spring, just require the central diameter D of this spring enough large, and the diameter d of the material of spring own is enough little, because the elastic force of compression helical spring is curled up than (D/d) and the isoparametric impact of compression height, the spring designing by mentioned above principle can not produce enough elastic force, cannot meet usage requirement.
Summary of the invention
The object of this invention is to provide a kind of Compress Spring, realize littlely at axial space, diameter requires large and the requirement of enough elastic force can be provided.
Concrete technological scheme of the present invention is, Compress Spring is the annular of the sealing made from elastic material, in described annular, be provided with the complete waveform of at least 2, the parameter of described waveform is identical, and crest and the trough of waveform are pressed in respectively between two parts that elastic force need to be provided in use, make the distance of Wave crest and wave trough diminish and produce elastic force.
The present invention can become ring, square or polyhedron shape by the annular design of sealing, to adapt to different requirements of installation space.Described Compress Spring is multiple, and the crest of each spring and crest, trough and trough be superimposed, or each spring crest is connected trough.Described Placement is splicing, riveted joint and welding, or between adjacent two single springs, is provided with spacing pad, and the material of described spacing pad is rubber or plastics.
In the annular of the present invention by the sealing of making at elastic material, design complete waveform, in the time bearing axial force, the distance between Wave crest and wave trough diminishes and produces elastic force; The increase and decrease of the quantity by waveform, or carry out the modes such as multiple springs superpose, can meet the usage requirement of different elastic force; In the time that multiple single springs superpose, also can, by the quantity of increase and decrease spring, reach the object that adapts to different usage requirements.In addition, because the present invention can be designed to different shapes, be designed to circle and connect by crest, the trough of waveform, can substitute common helical spring; Meanwhile, when the Environmental Conditions of spring is while being non-circular, because the present invention is by multiple stacks, add man-hour at single spring, simple punching press just can realize, and operation is simple, easy to make, has the unrivaled advantage of common helical spring.The present invention is simple in structure, and cost of production is low, can be large in radial diameter, in the situation that axially installing space is little, use, and meanwhile, flexibility of the present invention is strong, applied widely, by simple improvement, just can adapt to different usage requirements.
