Description

A kind of centering block coordinates cam follower explosive motor dynamical system

Technical field

The invention belongs to a kind of explosive motor field, it is related to a kind of centering block and coordinates cam follower explosive motor dynamical system System.

Background technology

Piston IC engine is the internal combustion engine come out earliest.It is characterized in that piston does reciprocating linear motion in cylinder, passes through Slider-crank mechanism realizes crank up movement output.Complete air inlet, pressure are completed once within two weeks in inside cylinder in crank up Contracting, acting, exhaust four courses of work, i.e. Otto cycle.It is conventionally believed that, internal-combustion piston engine has thermal efficiency height, knot Structure is compact, mobility strong, the advantages of operation maintenance is easy, it is even contemplated that the power set of piston IC engine, especially machinery knot Structure, has reached the degree reached the peak of perfection.However, the acting process of piston IC engine output power only account for therein four/ One, thus motor fluctuation is big, it is necessary to continuous by flywheel maintenance work process, particularly its thermal efficiency only has 40% or so.It is living Structure of Internal-Combustion Engine is filled in, form is single, lack changeability, power is only improved by increased in size or many set system parallel connections；Moreover, Limited by slider-crank mechanism characteristic, the chemical energy that expansion stroke is produced is difficult effective utilizes：As fuel explosive force is most powerful Period, exactly correspond to crank and be in dead center, now explosive force is main based on in-fighting, can not because the arm of force is close to zero Produce maximum drive torque；Maximum arm of force length and piston stroke are depended at fixed crank length, correspondence maximum arm of force, combustion The explosive force of material has declined a lot, and the composition of piston internal combustion mechanism of ocean congenitally determines that it can not possibly fully convert fuel Chemical energy.This is also the basic reason that piston internal combustion engine efficiency is difficult to improve.

Triangle rotator internal combustion engine (also known as triangular piston rotary engine) is in the rotor of currently the only successful commercialization Combustion engine.Triangle rotator internal combustion engine has one or more curved line trangle rotors with isometrical characteristic, has similar ellipse specific Make cylinder in the rotor storehouse of inner chamber profile；Rotor has three faces and casing wall just to form three separate spaces, i.e. combustion chamber.It is logical Bent axle and gear engagement are crossed, rotor is forced planetary motion in cylinder, during rotor motion, regularly exposes intake and exhaust Hole, being not necessary to be equipped with three combustion chambers of special valve as piston IC engine each can successively complete Otto cycle.Rotor Instead of the effect of piston, rotary motion output is converted the pressure to.Rotor continuously rotates in one direction, rather than tempestuously Change nyctitropic linear reciprocating motion.Three-apexed rotor is from circling, and engine ignition does work three times.Triangle rotator internal combustion engine is preferable Ground solves the problems, such as end face seal and radial seal, simplifies structure, and small volume, light weight, operation is quiet, and noise is small, with equal Even torque characteristics.But it is too high to still suffer from core members processing request, the difficult, thermal efficiency is adjusted to abrasion excessively sensitive, compression ratio Low key issue, combustion utilization efficiency is still difficult to be improved.Meanwhile, similar to piston IC engine, triangle rotator internal combustion engine structure can Expansion is also limited.The expansive force that other fuel is produced is when being converted into the power of output shaft, and the transmission of power is present naturally Defect.Although expansive force energy drive rotor rotation, it, which is acted on, makes a concerted effort to be difficult to improve to torque of armature spindle, equally interior loss-rate Example is too high.

The existing fuel used species of internal combustion engine is a lot, such as gasoline, diesel oil, kerosene, natural gas, oil gas, coal gas, hydrogen Deng.The fuel supply mode of dynamical system has two kinds in internal combustion engine working process：One kind is fuel gasification or atomization and oxidation Enter combustion chamber after agent (being typically air) mixing together, another is that combustion is individually filled by filling apparatus, not with oxidant Synchronously enter combustion chamber.Ignited fuel mode also has two kinds：One is ignited using igniters such as spark plugs, and another is by pressure Spontaneous combustion, such as diesel oil after contracting heating.

The content of the invention

The inspiration applied by cam mechanism in pump and motor configuration, then carried out for internal combustion engine Otto cycle particular/special requirement Transformation, after the key technology changed in order of Four processes of breakthrough, is proposed in a kind of rotor based on compound cam mechanism Combustion engine power set principle of compositionality.

Basic Design thinking is：Cam dead axle is arranged on to the inside of cylinder, is far stopped using cam and area and closely stopped Area forms the annular gap changed, then the annular gap is circumferentially separated into multiple sealings with one group of driven member to footpath difference Chamber, and with the gas working condition of each chamber of valve control, as long as realizing rational radial seal and end face seal, it becomes possible to Realize and utilize the piston-engined identical course of work.Moreover, rotary polygonal piston engine has been radial seal and end face seal There is provided good precedent.

According to the flexibility of Cam Design, the forms of motion of cam follower includes translating follower, swings driven Part, and direct acting swing compound several forms of plane motion driven member.The working end of driven member can divide pinnacle, dome, put down again The form such as top and roller.Cam may also differentiate between as appearance face cam and cam, disc cam, columnar cam, globoidal cam in itself Deng, add cam contour shape, lift and backhaul changing rule, it is far and near stop whether there is and quantity etc. difference, can produce Raw different design result.Although these factors can all realize above-mentioned thought, structure arrangement meeting using identical principle There is certain difference.

Structure disclosed by the invention is outline cam and centering block is the organization plan of oscillating follower combination.

Basic design scheme is：In rotor storehouse, cam follower is installed by end member dead axle, end member is with turning Sub- storehouse and cam follower constitute end part seal；Cam follower outer surface is what plane smooth curved section was rotarily formed around central shaft On the surface of revolution, forming process median generatrix each point to footpath synchronously change, its end profile is the closure plane curve of fairing everywhere； The inwall in rotor storehouse is also the surface of revolution, so as to constitute the annular gap changed to footpath difference with cam follower.Inside rotor storehouse and Some middlewares are also equipped between cam follower cam contour surface, middleware is swinging block, and centering block is used as cam follower, one End is connected with making centering block groove on rotor storehouse, and there are sealing, the other end and cam follower profile in junction along whole connecting length Sealable higher pair connection is constituted between face, so that annular gap is separated into some distance pieces；

Centering block and the end junction in end member and/or rotor storehouse also constitute sealing, turn rotor storehouse inner surface, cam The work chamber of several sealings that are separated, these sealed chambers are formed between outer surface, centering block and the end member of son Can occur volume change with the relative motion between cam follower and rotor storehouse；

There are air inlet and exhaust outlet opening in these work chamber, it is controllable in the case where the valve that valve timing controller is controlled coordinates The flow direction of gas processed, so as to be sequentially completed the intake process of Otto cycle, compression process, igniting in each work chamber The chemical energy that fuel combustion is produced is converted into cam follower phase by expansion work process and exhaust process, expansion work process The mechanical energy exported to rotor storehouse in gyration form.

Rotor storehouse and cam follower can as gyroscopic output tumbler, end member with both of which keep end it is close Seal and make between the two with respect to fixed-axis rotation on the premise of, can be fixed as one with one of both, also can relative both be independent.

The bus of the inner chamber in rotor storehouse and the appearance surface of revolution of cam follower can be the simple flat surface curves such as straight line, camber line Or it is combined, the section cam contour perpendicular to rotating shaft of cam follower should make the centering block for constituting cam mechanism relation therewith in fortune Rigid shock and/or soft impulse are not produced when dynamic, i.e. without velocity jump and sudden change of acceleration.When can so be conducive to operating The stability connected between centering block and cam contour, also avoids composition surface from impact wear occur, so as to improve service life.

Cam contour, which should try one's best, avoids local discontinuously place, otherwise, should try to ensure that sealing when centering block is contacted here.

Cam contour can be a variety of using straight line, circular arc, SPL, sine and cosine curve, polynomial curve, elliptic curve etc. The conventional curve of cam contour, or combined by several.

Cam contour is preferably provided remote stop section and/or section of closely stopping, even if the higher pair connection end of centering block is apart from cam The most distant and nearest place position remains stationary of axle cam contour section, to realize the relatively simple characteristics of motion of centering block, reduce its with The relative motion in rotor storehouse, so as to reduce abrasion.

Centering block is arranged on rotor storehouse in the corresponding centering block groove made, the external part shape that contact with cam contour surface and Cam surface of revolution shape of generatrix is consistent.

Contact of the centering block with cam can reach that such as centering block trench bottom sets rigidity by being easier the force-closed of realization Appropriate spring or hydraulic coupling, can also be realized by geometry closing form that is high-precision or being compensated with radial deformation.

For compensation centering block end wear, strengthen sealing, centering block can be made into balanced form, such as use many piecewise combinations Structure, middle part end face is the angle stake docking coordinated, reaches by a small amount of axile displacements to realize that end face seal is compensated；Also it can adopt With multi-disc congruent manner compensation end part seal and enhancing radial seal etc..

Appropriate location is opened between central component, centering block and in the working chamber of cam ring rotor composition for air inlet and exhaust outlet Mouthful, and control it to be opened and closed by valve respectively.

When cam follower and the relative rotation of rotor storehouse, the volume of the work chamber separated by centering block is continually changing.

In addition, setting igniter according to using the necessity of fuel, igniter should be arranged on gaseous mixture and reach regulation The corresponding position in combustion chamber during compression ratio.If the opportunity of fuel adding is not synchronous with the oxidant such as air, fuel filling device Fuel adding entrance should be arranged on intake process and compression process it is corresponding it is interval in.

Single set of the present invention covers dynamical system more, coordinates other lubricating systems, cooling system, air distribution system, control Other accessory systems such as system, you can constitute complete internal combustion engine.

A kind of centering block disclosed by the invention coordinates cam follower explosive motor dynamical system, is used as the core of explosive motor At least there is following visible advantage in the heart：

1. the power that burning is produced is directly acted on the output rotor of dead axle revolution, returned using with the continuous dead axle of rotor Then occur the working chamber of volume change, and the pressure energy of fuel combustion generation is directly absorbed, without any motion transform process, from And it is short to move transmission link, be conducive to improving transmission efficiency.

2. no matter produced in Fuel explosion at maximum explosive force, still phase after combustion, the arm of force of active force can be kept It is constant, therefore blast pressure can be fully used.

3. system can accomplish that rotor is turned round without acceptance of persons, system balancing is easily realized, therefore stable movement, is added without reciprocal fortune Moving part, kinetic equation loss is small, and system vibrations are small, and low noise operation can be achieved.

Embodiment

Below in conjunction with accompanying drawing and technical scheme, illustrate that it is constituted substantially with instantiation.The too many change due to existing, it is first First operation principle is demonstrated with a simplest example.

For ease of accurate understanding, first reaffirm the related definition of several cam mechanisms：Make centering block to away from cam center axle side It is referred to as lift to the process of motion, conversely, making centering block to the process moved close to cam center direction of principal axis referred to as backhaul.Correspondence pendulum Block distance center axle remotely remains stationary cam contour section remote area of stopping, correspondence centering block is nearer in distance center axle Locate the cam contour section of remains stationary nearly area of stopping.

Embodiment one

See accompanying drawing 3, it is assumed that rotor storehouse is fixed, cam follower is to have the disc type in one section remote stop area and one section of nearly area of stopping convex Wheel, far angle of repose and near angle of repose are slightly less than 180 °.The quantity of centering block is 2, is arranged symmetrically.Overall sealing relationship after assembling As before, no longer repeating, centering block center has the less face of cylinder to coordinate, and free end is also provided with the sealing cylinder of partial concentric.This Sample, the outside of centering block, can be passed through hydraulic oil realize cam and centering block contact it is force-closed.Air inlet and each two of exhaust outlet, if On rotor storehouse, live apart in the both sides of centering block, illustrated with the movable block for representing valve, wherein the corresponding air inlet with small circle Mouthful.A pair of inlet and outlet mouthful are one group, continue to use the cam rotation direction of curved arrow instruction, are ranked forefront with air inlet in group, exhaust outlet Do not limit.Igniter sets two.

Two centering blocks will be divided between rotor and rotor storehouse above and below two working chambers, rotor rotate when the two same time-varying of chamber volume Change, while a change is big, another reduction.And the big process of volume change can correspond to two processes of air inlet and expansion work, and Volume reduces can correspond to two processes of exhaust and compression respectively again.Four kinds of assembled states are may occur in which when therefore starting.

Below first by air inlet when starting -- compression combination is discussed：

During beginning, cavity of resorption air inlet, while epicoele compresses.Working condition see the table below in valve state, chamber in the course of work.

Ensuing (9) stage is identical with (1) stage, that is, returns to circulation original state, it is seen that is one and infinitely follows Ring process.

Due to the special parameter relation of this example, if circulation is correspondence compression and acting (3) stage since figure Combination；If circulation is correspondence exhaust and acting combination (5) stage since figure；If circulation (7) rank from figure Section starts, then is correspondence exhaust and air inlet combination.Thus the difference of this example initial pool does not have any difference.But example below It will indicate that, the difference that initial pool is set produces different application effects sometimes.

In this example, in rotor two weeks, there is continuous acting process twice, acting every time lasts about 180 ° of angles, total acting Power output angle about one week, i.e. there is acting power output a half period.When this example is used alone, rotor continuous rotary in the same direction has Certain energy storage effect, can be achieved to continuously run, but coordinate flywheel using being more beneficial for stable movement.If using many set systems Serial or parallel connection is used, and make each set system without output power-section and dynamic output area reasonable combination, can remove special from The energy storage device such as flywheel.Compared with piston IC engine, although Otto cycle is both to be completed in two turns of output shaft, but this example Process of doing work twice is completed, power output angle increases one times.

This example is only the performance having in the case of given relation, and parameter change can cause more complicated change, at that time Initial pool state may correspond to entirely different cyclic process, it may appear that the overlapping of multiple power phases, continue or separate Pattern.This point shows especially prominent more in centering block number and cam crest number.

Here the remote of cam, near angle of repose only make the motion ratio of centering block more simple, are not necessary, as long as can cause work Make chamber volume to change and realize that the cam of required compression ratio can be used, simply the rule of volume change is more complicated.Enter in this example Exhaust outlet is set in rotor storehouse inner cylinder, can be also arranged on centering block by the way of appropriate or rotor storehouse end face on.Even When being necessarily placed at because of factors such as rotor storehouse rotations on cam cylinder, it only need to further solve centering block and be located at gas with cam contact point Sealing problem during mouth position between adjacent working chamber, can such as be covered in before gas port simultaneously enough using the seal f ace width of centering block The mode on edge is realized afterwards.

Point out that air inlet is forward along band so that the air inlet just reverse air inlet of section, airflow direction and cam face friction rolling, Fuel and air is conducive to mix.Just section, there is also gas transfer, is conducive to fully burning to acting process.

Embodiment two

Demonstrate slightly complicated situation by Figure 4 and 5 again below.

Rotor storehouse is fixed, and the cam follower for having cam contour makees output.Rotor storehouse is provided with three centering blocks by rotor storehouse Three sections are evenly divided into, cam follower has one remote stop area and a nearly area of stopping respectively, angle of repose is substantially as schemed, i.e., convex The remote of wheel rotor stops that corresponding central angle between area and two centering blocks is close, and the space between two centering blocks is working chamber or combustion chamber. Figure 4 and 5 show during rotor diverse location the course of work in corresponding valve state and chamber.There are three working chambers, per chamber when initial There are two kinds of possible courses of work, thus there are 8 kinds of different work in combination patterns.Two kinds are shown here only, remaining is not opened up one by one Open discussion.

The first pattern：

Fig. 4 is to stop after being done work air inlet, right chamber since as chamber, compress these three process composite states cavity of resorption and open Begin.So-called process of stopping, i.e. working chamber volume keep constant transition state.Show that this example undergoes 12 stage rotors in figure complete Into two weeks, and return to original state.

Ensuing (13) stage returns to circulation original state, identical with (1) stage.

Air inlet is forward so that intake process has reverse gas transfer process, it is easy to improves mixing uniformity, but enters vapour lock Power is slightly larger；There is one section of process of stopping after air inlet and after acting, be conducive to heat exchange.In this pattern, turned round in rotor in two weeks A work period is completed, three Otto cycles are realized, three chambers respectively complete process of once doing work, acting lasts about 120 ° per chamber, 120 ° are spaced between the acting of two chambers, energy output total angle is about 360 °, and unpowered output area is also about 360 °, is characterized in one Half period dynamic output, power output stability is high, and fluctuation is small.

Second of pattern：

Fig. 5 is to stop acting, right chamber after air inlet since the left chamber, compress these three process composite states cavity of resorption and open Begin.Show that this example undergoes 12 stage rotors and completed two weeks in figure, and return to original state.

Ensuing (13) stage returns to circulation original state, identical with (1) stage.

In this pattern, turned round in rotor and a work period is completed in two weeks, realize three Otto cycles, three chambers are respectively completed Once do work process, per chamber, acting lasts about 120 °, without interval between doing work twice, continue 360 ° of acting, unpowered output area Also it is continuous one week.A half period dynamic output is characterized in, power output is strong, but the first relative pattern fluctuation is slightly Greatly.

This example is compared with upper example, although acting duration angle reduces, but if using appropriate big warehouse diameter, acting correspondence Arc length but can it is constant in addition increase, other specification regulation it is also such.When this example is used alone, cam continuous rotary has certain Energy storage effect, can be achieved to continuously run, but coordinate flywheel using being more beneficial for stable movement；If using many set Cascade Systems Or it is used in parallel, and make each set system without output power-section it is corresponding with the dynamic output area of other systems, not only can in order to avoid The energy storage devices such as special flywheel are removed, and dynamic property is stronger.

Embodiment three

Fig. 6 further shows variability.As long as circumferential space is sufficiently large, the quantity and cam hump of swinging block (are stopped as remote Only area) quantity can arbitrarily increase.Plus centering block block release, the size for completing the working space of each working cycles also may be used Change.

The parameters relationship selected below, simply to illustrate that it is convenient, clear, and without limited.Cam is set in figure to turn The remote section of stopping of son is uniform two, and the arc length for section of stopping is slightly larger than the corresponding arc length of adjacent two centering block, and having makes two centering blocks same When the state in retraction.Centering block quantity is taken as 6 and uniform, with numeral instruction.Each centering block is controlled by centering block release, Wherein " de- control " represents that centering block is decontroled by release, and " controlled " expression centering block is blocked by release, and " entering control " represents The opportunity that centering block is blocked by release, " freeing " represents the opportunity that centering block is decontroled by release.Porting a, b, c, d, E, f air inlet and exhaust outlet are set up in parallel vertically, are only to illustrate in figure, slightly longer for air inlet, slightly short for exhaust outlet. The action moment or state of valve are shown, what it is with small arrow is action moment in figure, without the state for holding of arrow.Work The course of work of chamber is abbreviated as into (air inlet), pressure (compression), work((acting), row's (exhaust), and " beginning " table begins to start, " in " represented Cheng Jinhang, " complete " expression process is finished, and compresses and there is ignition process conversion centre of doing work, do not mark.

Assuming that rotor storehouse is fixed, the gyratory directions of rotor is shown in curved arrows.Band arrow is bent in inlet and outlet route chamber Line is represented.

Cam follower structure shown in Fig. 6 has two remote section of stopping, and 6 centering blocks are combined into the working chamber of varying number.Such as, Without using centering block release, it can be used by 6 geometry working chambers；Using centering block release, then according to being controlled temporarily Centering block number difference is divided into 5,4,3,2 working chambers etc. are several.Per at least two kinds different processes of chamber when initial, can have much not With the mode of operation of combination.

It is using 4 chamber operation control modes, while the centering block number being stuck is two, two neighboring geometry shown in Fig. 6 Working chamber is controllably applied in combination, and each chamber is followed successively by air inlet, compression, acting, exhaust by cam gyratory directions when initial.

Centering block " entering control " and " freeing " are completed in the top dead centre stage, and centering block motion can be avoided to impact.Therein " half Pressure " refers to that working media is only compressed to half way, does not recompress；" surplus row " refers to that combustion chamber has waste gas residue not discharge.

The course of work is as follows：

A mouthfuls of correspondence working chambers of sequence number (1) are independent, prepare air inlet；Centering block 2 and 5 is controlled not to be extended out, b working chambers corresponding with c mouthfuls Connection, prepares compression；D mouthfuls of correspondence working chambers are independent, will be done work after igniting；E is also connected with f mouthfuls of correspondence working chambers, prepares row Gas.

Sequence number (2) is due to the de- control of centering block 3 and 6, along cam contour reverse-running section under seal force or the effect of geometry enclosed construction Show to nearly area of stopping, keep a point chamber border.Cam follower is rotated, and each chamber process is slightly in progress, i.e., a oral cavities volume passively expands, Air inlet；B, c mouthfuls of joint chamber volumes passively reduce, and compress；Done work after the igniting of d oral cavities, accelerate drive rotor to rotate forward, volume increases Greatly；E, f mouthfuls of joint chambers passively reduce, and are vented；Now, centering block 1 and 4 is in de- control state and contacted in remote area of stopping with cam face, A point chamber border is kept, and in retraction centering block groove, control can be entered at any time, and the controlled state of centering block 2 and 5 is retracted in centering block groove, because For not with cam contact, a point chamber border is not constituted, can not make it free stretching yet, otherwise cam can be caused tap.

Along reaching at centering block 2 and 5 after sequence number (3) cam lift, the area of smoothly far stopping with cam of centering block 2 and 5 forms close Sealing-in after touch, is freed, and builds new point chamber border, and each chamber process is in progress again；Now, b, e oral cavity are independent, in six chambers point Vertical state.Now centering block 2 intercepts and captures half-compressed gas in combustion chamber from b oral cavities, and centering block 5 intercepts the waste gas that e oral cavities combustion chamber is not arranged. Centering block 1 and 4 still keeps being retracted in centering block groove, stable before remote area of stopping is departed to enter to control, and is easy to next conversion.

Sequence number (4) cam is rotated further, and centering block 1 and 4 is controlled no longer to be shown along cam backhaul, so that sealing is exited, because of pendulum Block 2 and 5, which is freed, has taken over sealing, and a connects restructuring with b mouthfuls of corresponding cavities, and b oral cavities half-compressed gas is incorporated into intake process, e and d mouthfuls it is right Chamber connection is answered also to recombinate, e oral cavities remain exhaust and are mixed into acting process, meanwhile, c oral cavities independently execute acting, f oral cavities and independently execute row Gas, each chamber process continues.

Sequence number (5) just pushes back centering block 3 and 6 in centering block groove until cam lift again, and a and b mouthfuls of corresponding cavities complete air inlet, Restructuring air inlet is realized, air inflow is improved；The compression of c oral cavities terminates, and realizing conjunction chamber compression can light a fire；D, e combination completion are done Work(, realizes and closes chamber acting, increase working stroke；The exhaust end of f oral cavities realizes conjunction chamber exhaust.

So far, Four processes during beginning have been completed, and each chamber will start corresponding next process, and cam angle is 120°.Compared during with sequence number (1), original state is made with this, in addition to differing minus 60 ° therewith except angle position, remaining all same connects down The sequence number (6) and sequence number (2) come are also such；Thus, the as above six similar processes that need to undergo can be released, that is, rotor is turned round Two Zhou Houhui return to original initial state, therefore no longer completely show.

As can be seen here, 120 ° of every turn of rotor, it (but is not complete in same working chamber that can integrally complete Otto cycle Into), and acting process, with all the time, every turn can complete 3 works done, and course of work meeting Infinite Cyclic is gone down, without flywheel Also can continuously it be exported Deng energy storage device power.

As can be seen that the controllable centering block of multi-quantity makes the size of working chamber adjustable in use in this example, add dynamic The flexibility of power output, is also beneficial to improve the geometry utilization rate of working chamber and the utilization rate of fuel energy, with prominent advantage. From centering block control operability analysis is realized, although centering block release can be realized using machine driving control or hydraulic drive, But it should belong to the most convenient using Electromagnetic Control.

The structure of outline cam plus the internal combustion engine moving Force system of centering block combination is illustrated above by several simple examples Into, the method for operation and handling characteristics.It is envisioned that if radial dimension is sufficiently large, the quantity of cam follower not bounded Limit.Meanwhile, also do not limited similar to the cam hump number in far and near area of stopping, thus working chamber quantity can be with demand depending on. Control plus centering block release to centering block, design is flexible and can fully demonstrate out using flexibility.As for single-chamber volume, Compression ratio, combustion-chamber shape etc., can make full use of radial clearance and axial length to solve.In a word, the invention is sent out for rotor The research of motivation opens wide space.
