Its advantages include less friction loss, high volume efficiency and rotational speed, and low vibration and noise. It is suitable for compression, pumping and extraction of fluid.
Description
The present invention relates to a kind of rotary-piston volume-variable machine " coaxial multi-slip-sheet wave-ring rotor machine " of mechanical field.It comes down to the improvement and the development of inventor 92234322.5# Chinese patent " wave ring type line sliding rotary machine " (letters patent 153179# is hereinafter to be referred as former ripple ring machine), is that a kind of performance is more perfect, and the practical type of having succeeded in developing.
The sliding rotary machine be continue to use in numerous rotary-piston machines historical the longest a kind of.It sees it all is very succinct from complete machine structure or manufacturing process.Just it is failed to stop in 400 years of development courses always and takes off that frictional loss is big, mechanical efficiency is low; The sealing line length, leak bigger; The puzzlement of defectives such as capacity utilization is low.Thereby can only under mesolow power and middle and slow speed of revolution, be used as compressor or pump usually, can't in more wide technical specifications and application, compete with reciprocating piston machine.
Though present sliding rotary machine also has certain advantage in certain scope, on current market one seat can also be arranged.Such as: accompanying drawing 1, a are a kind of many slide plates air compressor (also being used for vacuum pump); Fig. 1, b are a kind of rolling piston machines, are common in freon compressore in minitype air conditioner or the refrigerator.They in fact with Lame in two kinds of types discussing in 1588 basic identical, see Fig. 2 a; B.They equally can not overcome the basic shortcoming of slide plate type in the Lame above-mentioned yet.In addition, directly be subjected to the powerful challenge of machines such as helical-lobe compressor and scroll compressor at present.As seen, if the sliding rotary machine does not still have breakthrough, perhaps will soon enter the row example of dispensed model.
Yet the inventor believes firmly: " U.S.A of science is succinctly ".Machinery is from having its flourishing long time vitality simply, efficiently.We think, as long as slide plate machine in the Lame is done with clearly defined objective improvement, make it that qualitative leap be arranged on performance, particularly have breakthrough at aspects such as saving energy and reduce the cost, improve rotating speed, just have new slide plate machine and dominate the market." wave ring type line sliding rotary machine " is exactly the initial achievements of this thinking.It amplexiforms mechanism at change slide plate and profile, improves the slide plate stress, reduces mechanical loss, and there has been bigger breakthrough aspects such as raising capacity utilization.But in our trial-production practice, find that former ripple ring machine scheme still has many shortcomings, introduces everybody " coaxial multi-slip-sheet wave-ring rotor machine " scheme now to through the last formation of failure, modification, raising again and again.
Accompanying drawing 3 is the schematic diagrams of " coaxial multi-slip-sheet wave-ring rotor machine ".Although it is the same with common sliding rotary machine, also be to constitute by stator (3-4), rotor (3-5), slide plate (3-7), end cap parts such as (3-1 and 3-6), but it has many novel original intensions that are different from general sliding rotary machine, and is specific as follows:
1. this type is the same with former ripple ring machine, and the inner chamber profile curve (3-14) of rotary-piston adopts " sine wave curve of going in ring " ρ=R+h (1+Cosn α), rather than general slide plate machine cycloid or circle commonly used.But we only recommend everybody to elect waveform parameter n as 3 specifically.The polar equation of the radius vector of its curve (being slide plate length) is: ρ=R+h (1+Cos3 α)
R is the stator radius in the formula, and h is that slide plate stretches out parameter, and α is that polar angle is an angle of rotor.Theoretical calculation proves: it is optimal selections of single rotor type that waveform parameter is decided to be 3.
2. ripple ring piston (3-5) is enclosed within the outside of the cylinder shape stator that diameter is 2R (3-4), coaxial circumscribed setting.External-change-internal is quiet, and promptly the ripple ring piston of periphery is rotor (so claiming the ripple rotor), and the cylinder of central authorities is a stator.This will bring a series of original advantages.
3. general slide plate machine has only a crescent working room, and this type ripple ring curve (3-14) cooperates three spans of formation with the stator circle of inscribe respectively be 120 ° crescent working room (3-8 is called for short arc chamber later on).These working rooms are extended the slide plate of stator and separate.Volume-variation just takes place in turn when the ripple rotor rotates.With the compression that is used for various fluids, pumping, extraction or with the fluid is the energy or the control transfer of heat of medium.
4. different with former ripple ring machine, this type adopts three secondary slide plates, and they are in 60 ° of angles of cut and pass through same axis (0 point among Fig. 3).Different with slide plate machine in the Lame, the slide plate of ripple ring machine must and run through stator through the stator center of circle.We become formula ρ=R+h (1+Cos3 α) as can be known by the wound of ripple ring curve, and any radius vector sum strictness by 180 ° of two phase differences on the straight line of central shaft 0 equals 2 (R+h).So the slide plate of ripple ring machine all must pass through the center, and length should equate.Slide plate can not disturb mutually, free-running operation independently of one another in order to guarantee respectively to organize, and we are decomposed into the fixed length slide plate of former ripple ring machine and keep the two ends slide plate, middle with two push rods (3-11) get in touch, the way of crossings on different level setting realizes this requirement.Two slide plates on same diameter are one group, and the length of each slide plate group all equals 2 (R+h).Each slide plate group is equivalent to a fixed length slide plate of former ripple ring machine.It can guarantee both to be driven by the rotor profile equally, amplexiforms mutually with the rotor profile constantly again.Play effect with the airtight separation in crescent working room.
5. a corresponding therewith machine cylinder shape stator has three groups six vane slots (3-15) along diametric(al), apart 60 °, has two groups of through holes up and down along diametric(al) between two vane slots on the same diameter, the middle push rod of placing.Push-rod hole on the different-diameter staggers mutually.In some applications, these push-rod holes can be used as stator middle part accumulator provides passage from machine oil to vane slot.
6. this type is the same with general slide plate machine in a lot of applications, and each Surface of action of engine oil supplying and potted line endlessly should be arranged in the running, to do lubricating sealing, the usefulness of cooling.This machine cylinder shape stator central authorities are used as machine oil storeroom (3-3).Machine oil is introduced by passage (3-10).
7. the quiet characteristics of this machine external-change-internal can also make the cooling wing (3-12) of ripple rotor and its periphery join together.The cooling wing of surrounding rotor can be designed to spiral.Can force surrounding atmosphere to flow during running, strengthen cooling effect.
8. the fluid input output of this machine all are omnibearing basically, generally all carry out continuing under any corner.Usually import and export need not the regularly linking mechanism of keying.This not only simplifies the structure, and to reducing noise suitable effect is arranged also.
Fig. 3 draws by the air compressor purposes.Intake duct (3-2) is opened on a side of ripple rotor, inhales people's air via the intake duct on the end cap.And exhaust port (3-9) is located on another cover plate.Relief opening is provided with the one-way pressure-limit valve (3-13) that steel ball spring constitutes, so that exhaust again behind the savings certain pressure, and guarantee that the gas of discharging can not return the working room.Certainly, also can make leaf valve or other Non-return air valve into.When making other purposes, this type just not necessarily needed one-way valve.
Below we briefly narrate the long-pending working procedure of transfiguration of coaxial multi-slip-sheet wave-ring rotor machine:
If ripple rotor (3-5) is clockwise direction rotation (otherwise the same) under motivational drive.At this moment three arc chambeies being surrounded of the profile of ripple rotor and stator cylinder will be passed through each slide plate in turn.We investigate the wherein variation in some arc chambeies: such as that arc chamber on right side in Fig. 3 top view.This moment, its main body was divided into the (3-17 of former and later two working rooms by level slide plate to the right; 3-16).Ours here preceding with after be with the rotation direction of advance be as the criterion.Along with the rotation of rotor, working room, the place ahead (3-17) will continue to enlarge; (3-16) then also constantly dwindling the working room, rear; At this moment the arc chamber forward tip that strides across last slide plate (being that a slice of bottom right five o ' clock positions) has then generated a new working room, the place ahead in this slide plate the place ahead.Afterwards, (3-17) will be and begin to dwindle as the trailing chamber of bottom right slide plate; After this, the trailing chamber of right horizontal slide plate (3-16) is with complete obiteration.And then, after the shortest radius vector of ripple ring curve is partly crossed right horizontal slide plate, the most advanced and sophisticated of one arc chamber, back partly will produce new working room, the place ahead in its place ahead, and constantly enlarge.At this moment also can be as the 3-17 of the trailing chamber of bottom right slide plate as the very fast disappearance of 3-16.This process hockets in three arc chambeies simultaneously.They are always like this: the working room in slide plate the place ahead constantly enlarges; The working room at slide plate rear then constantly dwindles simultaneously.Then when crossing the slide plate top, finishes the shortest radius vector of ripple ring curve the final disappearance of trailing chamber and replacing of new working room, the place ahead generation.Working room, the place ahead then reaches maximum value at the maximum radius vector of ripple ring curve during by the central position between two slide plates, and is converted into the trailing chamber of last slide plate, begins then to dwindle.So circulation repeats.Obviously, the ripple rotor whenever circles, three inswept in turn six slide plates in arc chamber, finish altogether complete grow out of nothing for 18 times, from small to large and from big to small, until the long-pending process of the transfiguration that disappears.N is that rotating speed, Vo are the maximum volume of single working room in thereby the Theoretical flowing capacity of this machine: V=18n * Vo formula, and it can be determined with the method for mathematical computations or actual measurement simply.Here it is, and this machine is directly produced the overall process of volume-variation by simple rotation.
Here it is to be noted especially that type is different fully in the mechanism that slide plate is close to profile in the ripple rotor machine operation process and the Lame: it neither participates in the centrifugal force that rotatablely moves by slide plate; The also elastic force of back-rest mounting spring not, but by the slide plate group really measured length guarantee with the method for geometry of the straight line of crossing the center in this position and the equal in length that the profile curve intersection is intercepted all the time.Certainly, the profile curve must be " sine wave curve of going in ring " of the special design for this reason of the inventor, only in this way could guarantee everywhere, constantly, any angle all conforms to above-mentioned requirements.This physical dimension of utilizing profile drives the design that slide plate is done restricted motion and amplexiformed with profile all the time, has reduced the friction loss between slide plate and profile greatly.Also created condition for the rotating speed that improves the slide plate machine.
In addition, the design increases to three groups reason with slide plate and is: although the center of gravity strictness forever of ripple rotor itself overlaps with rotating shaft during because of former ripple ring machine running.But the to-and-fro motion of single slide plate still can bring small vibrations to rotary piston machine.After using three secondary slide plates instead, though each slide plate is all moving, then no matter rotor can both guarantee in what corner, that position to overlap (this also must match with belt sine wave curve certainly) with rotating shaft forever their common center of gravity.This has just guaranteed that this machine is in service any small vibration can not take place.Another benefit that increases to three secondary slide plates is to have improved the volume utilization ratio of rotary piston machine greatly, from time transfiguration one Saturday of former ripple ring machine revolution, increases to 18 transfigurations of revolution.This has just almost improved three times with air displacement under the prerequisite that does not increase machine volume.Compare high more of its volume utilization ratio with the only transfiguration of whenever circling of other slide plate machines.
This type is different with former type, and the interval of two adjacent slide plates shortens to 60 ° by 180 °, and this has not only eliminated the intermittence of 60 ° of corners that had in the former machine transfiguration process.And the function of working room, slide plate both sides is contrary by overall process, become that certain angle range is arranged is the mode of identical operating mode.This has just eliminated all contingent porting of many slide plate types and has scurried logical phenomenon.Also reduced the leakage of working medium between adjacent working room.
In sum, coaxial multi-slip-sheet wave-ring rotor machine has not only been preserved slide plate machine structure and all very succinct advantage of technology in the Lame fully, has more realized a series of original improvement: simplify motion mode, to improve force-bearing situation; Change slide plate and profile and amplexiform mechanism, to reduce friction, to reduce power consumption; Increase slide plate, to improve the volume utilization ratio; Reduce centre-of gravity shift in the running, shake with the elimination machine; Realize comprehensive intake and exhaust, exempt regularly opening/closing mechanism, to reduce aerodynamic noise; Can also improve the running speed of this machine greatly based on above effect.
Just because of this, the application area of coaxial multi-slip-sheet wave-ring rotor machine will substantially exceed existing slide plate machine.Except because of its surface to volume ratio is still bigger, be used for rotary engine opportunity still immature beyond, almost be applicable to other all applications of piston machine.Below we recommend several most characteristic, the application that can succeed in developing in the recent period:
1. in view of can be designed as, this type do not have interior compression process operation; The thickness of slide plate can design greatlyyer; But the external rotor transfer larger torque is specially adapted to big-flow high-pressure oil pump or oil hydraulic motor.
2. this type intake duct is concentrated a place, be easy to be developed to the high-speed large-flow vacuum pump.
3. the characteristics little in view of this type volume, that discharge capacity big, vibration is little, noise is low, the machine of big discharge capacity also need not pile foundation again are suitable for most developing the mobile air compressor plant that makes pneumatic tool in road, the bridge stack engineering, and other multipurpose small mobile compressor.
4. we can also unite ripple annular space air compressor and ripple ring decompressor utilization exploitation refrigerator with air medium refrigerator or domestic air medium air conditioner same reason.
