Abstract
The utility model provides a wave spring for an air valve of a compressor, which belongs to the technical field of springs. The wave spring for an air valve of a compressor solves the problems of the existing wave spring of small elasticity, short action travel, low strength and the like. The wave spring for an air valve of a compressor is formed by spirally bending a bar-sheet body, and the total wave spring is in a cylinder shape. The body is spirally bended, and meanwhile, the body is bended up and down to axially suspend sinusoidal waveforms; however, the crest of the sinusoidal waveforms contacts the trough of the sinusoidal waveforms of the last ring. The body of the wave spring for an air valve of a compressor is spirally bended, and meanwhile, the sinusoidal waveforms are axially suspended; however, the crest and the trough of adjacent two rings are opposite to enable the wave spring to counteract residual stress; and the stress is even. Thus, the prepressure is increased; the self strength of the wave spring is improved, so the wave spring is not easy to break off; meanwhile, the stability of the wave spring is the improved, and the life is prolonged.
Description
Technical field
The utility model belongs to the spring technical field, particularly a kind of wavy spring that is used for compressor valve.
Background technique
Spring is a kind of mechanical parts that utilize elasticity to come work, impacts or shake, stores up the size of energy, measuring force etc. in order to motion, the mitigation of control parts.The kind complexity of spring is various, by the shape branch, mainly contains helical spring, spiral spring, leaf spring etc.Wherein helical spring is widely used in machine, the instrument the most.
At present, in compressor valve, use common helical spring and have more problem, identical as common spring rotation direction, discontinuity, poor stability easily causes residual stress, thus spring breakage; Simultaneously common spring also exists elasticity relatively poor, and fatigue limit, impact toughness are lower, and bearing capacity is little, the problem that the life-span is short.So the wavy spring of people's model utility, for example, Chinese patent literature once disclosed a kind of defence nut [Chinese patent application number: 200810120671.6; Publication number CN101403453A] in elastic component, shown in 4 in Figure of description 1 and the Figure of description 2.Though this elastic component is optimized common spring, improve intensity and stability, be applied to also exist in the compressor valve elasticity little, load-carrying properties are poor, and the effect stroke is short, easily produces defectives such as residual stress concentrations.Simultaneously, in " People's Republic of China's chemical industry standard one mechanical seal wavy spring technical specifications ", a kind of biplate three ripple springs are provided, because this spring is welded by two monolithics, three ripple springs, easily causes residual stress concentrations at soldering point, causes spring breakage, simultaneously still exist elasticity little, unbalance stress, load-carrying properties are poor, and the effect stroke is short, defectives such as intensity is low, and the life-span is short.
Summary of the invention
The purpose of this utility model is to have the problems referred to above at existing technology, has proposed a kind of wavy spring that is used for compressor valve of crooked simultaneously axial overlaid waveforms in the shape of a spiral.
The purpose of this utility model can realize by following technical proposal: a kind of wavy spring that is used for compressor valve, be that body by a long strip sheet forms through helical buckling, its whole formation is cylindric, it is characterized in that, described body is superposeing sine-shaped crookedly up and down in helical buckling vertically, and above-mentioned sine-shaped crest place contacts with the sine-shaped trough place of a circle on it.
Originally the wavy spring that is used for compressor valve is the bending extension and the sinusoidal waveform that axially superposes in the shape of a spiral, and adjacent turn crest and trough offset, thereby offsets residual stress, increases body intensity, make stressed evenly, stable, increase the life-span.
At the above-mentioned wavy spring that is used for compressor valve, the adjacent circle body of described body is two relative broad side face correspondences at axial direction.The body adjacent turn adopts wide relatively, and surface of contact is increased, and stability under loading improves precompression.
At the above-mentioned wavy spring that is used for compressor valve, each circle body has 3 sinusoidal waveforms at least in the described body.At least 3 sinusoidal waveforms make the force bearing point equalization stable on every circle body, increase bearing capacity.
At the above-mentioned wavy spring that is used for compressor valve, described body adopts metallic material to make.
At the above-mentioned wavy spring that is used for compressor valve, described metallic material is a spring steel.Body adopts above-mentioned material to have characteristics such as high-fatigue strength, good springiness, bearing capacity are good, high-and low-temperature resistance, corrosion resistance.
Compared with prior art, the sinusoidal waveform that superposes vertically when originally being used for the wavy spring body helical buckling of compressor valve, and the crest of two adjacent rings is corresponding with trough, makes spring offset residual stress, stressed evenly, thereby increased precompression; Improve spring body intensity, not easy-rupturing; Improve the stability of spring simultaneously, increased the life-span.
Description of drawings
Fig. 1 is the perspective view that originally is used for the wavy spring of compressor valve.
Among the figure, 1, body; 2, crest place; 3, trough place.
Embodiment
Below be specific embodiment of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As shown in Figure 1, the wavy spring that originally is used for compressor valve has body 1, sinusoidal waveform etc.
Specifically, the utility model is that the body 1 by a long strip sheet forms the whole columned spring that is through helical buckling, it is corresponding that the two adjacent rings body of sheet noumenon 1 is the broad side at axial direction, the body 1 sine-shaped up and down warp architecture that in helical buckling, superposes vertically, sine-shaped crest place 2 on the circle body with its on the sine-shaped trough place 3 corresponding one by one contacts of a circle, thereby the counteracting residual stress is stressed even, has increased precompression; Spring body 1 body 1 intensity, the not easy-rupturing of having improved simultaneously in wave shape; Improved stability.Have at least 3 sine-shaped curve waveform portions on each circle body of body 1, the curve waveform portion quantity on each circle body is many more, and the bearing capacity of spring is big more, improves precompression, and performance is good more, and the intensity of spring is high more simultaneously.Adopt each circle body to have 3 sine-shaped curve waveform portions in the present embodiment.
Spring body 1 adopts the spring steel in the metallic material to make, spring steel comprises carbon steel, manganese steel, Martinel Steel, Silichrome Steel, chromium steel, tungsten chromium vanadium steel etc., spring steel has higher limit of elasticity, fatigue limit, impact toughness, plasticity and good heat treatment process, has characteristics such as high-and low-temperature resistance, corrosion resistance simultaneously.The utility model flattens the coiling moulding by Round Steel Wire by the brilliant treatment process of ring, so material structure ringwise, thereby improves elasticity, increases the life-span.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
Although this paper has used body 1 morely; Crest place 2; Trough place 3 terms such as grade, but do not get rid of the possibility of using other term.Using these terms only is in order to describe and explain essence of the present utility model more easily; They are construed to any additional restriction all is contrary with the utility model spirit.
