Description
(1) technical field
The present invention relates to engine mechanism and device, especially the groundwork mechanism of rotary piston type engine and its application apparatus.
(2) background technique
The alleged power engine of this paper comprises the heat engine of internal combustion and open fire type and gas-liquid motor etc.The thermal power transfer that fuel combustion is produced becomes mechanical energy, heating power power engine from its arbor outputting power, public have a steamer, piston engine etc., piston engine is divided reciprocating type and rotary again: as Otto (Otto) the four-journey machine of invention in 1876, and wankel (Wankel) machine of Di Saier (R.Diesel) machine of invention in 1898 and nineteen fifty-nine invention.Type with reciprocating piston type in the above machine develops at most, uses very extensively in the agriculture transportation of industry, and role is very big.But because heat energy of its worker's Jie material of this power engine (working substance such as combustion and steam) or potential energy need to become its reciprocating mechanical energy by the piston in the cylinder earlier, pass to bent axle through the wrist pin connecting rod again, change into the mechanical energy that it rotatablely moves, export in the mode of torque from arbor, this shows the mechanism scheme of reciprocating type machine, there are the many and long problems of working link from the beginning, and piston, wrist pin, connecting rod, the motion inertia force of bent axle needs the problem of balance, and cause the parts of this power unit many thus, the structure more complicated, volume is big, heavy, shortcomings such as rotating speed can not be very high, and vibration and noise are bigger are difficult to fundamentally solve for a long time.
Wankel (Wankel) machine or title " rotary-piston " motor, claim wankel engine again, this invention was once attempted to address the above problem, its technical solution is to adopt semi-triangular piston, make it in the cylinder that point image 8 fonts are arranged, do a kind of mechanism of planet turnover motion, in cylinder, push (do turnover motion) piston by combustion gas, kinetic energy is delivered on the eccentric journal of eccentric shaft part, order about the main axis rotation of eccentric shaft part and export torque by piston.Because this scheme has been got rid of to-and-fro motion and connecting rod piston pin member, its main working link shortens, and eliminated the inertial force that reciprocator causes, make equilibrium problem simpler, therefore, once caused the great attention of world's industrial quarters at its invention initial stage, many countries comprise China, once participated in researching and developing, but still there is big not enough place in this technological scheme, is exactly that its triangle piston self does not possess the performance of moving voluntarily and working on structure in cylinder, must depend on increases by a pinion in addition and turns piston conversely, make its planetary motion operation as requested, this is under some influence its performance, and structure becomes complicated again; And the eccentric element of this structure, the equilibrium problem of its inertial force also fails to solve fully etc., this has just weakened the advantage of Wankel machine to reciprocating type machine, aspect having, be slightly better than reciprocating type machine though cause its performance, but the overall advantage contrast fails obviously to surpass, and has therefore just limited its development thereafter and has promoted the use of.
(3) summary of the invention
The mechanism and the device that the purpose of this invention is to provide a kind of power engine, the work of its groundwork mechanism of this power engine and transmission link are short especially; And the groundwork parts of this power unit are in when motion, and its inertial force should be easy to balance, preferably can be in from the state that balances each other, and to eliminate the shortcoming of aforementioned prior art, the structure of power unit is significantly simplified, and makes its performance excellent, and purposes is wide.
For solving above-mentioned task, the invention provides a kind of rotary piston type engine mechanism and a kind of rotary piston type engine device.A kind of rotary piston type engine mechanism is characterized in that: it transforms development by the secondary mechanism of full cycloid dead axle of engagement or planetary pinion in the tooth difference, uses as generation and the new purposes of transferring power, has the mechanism that produces power and transmission nature and function concurrently; The rotary-piston member of the roughly the same full cycloidal gear of shape and the cylinder member of the roughly the same full cycloid internal tooth of cavity shape are wherein arranged; A kind of rotary piston type engine device is characterized in that its groundwork mechanism has generation power and transmission nature and function concurrently, and the cylinder member is with the engine mechanism of piston component together with commentaries on classics or piston component turnover; The groundwork face that its piston and cylinder are made function is the full cycloidal cylinder that a secondary conjugation is nibbled mutually; Have in the device: the cylinder of the rotary-piston of the roughly the same full cycloidal gear of shape and the roughly the same full cycloid internal tooth of cavity shape.
For the ease of understanding, hereinafter contrast accompanying drawing, to technical solution of the present invention, rotary piston type engine mechanism, relevant full cycloid technological rudimentary knowledge and the principle of this power engine etc. are described further.
Rotary piston type engine mechanism is referring to Fig. 1 to 2, what the roughly the same full cycloidal gear of its shape of middle part that is positioned at figure had n convex-concave portion is exactly piston 1, and in this mechanism, arbor 4 and piston 1 fuse, become the piston component of a band arbor, i.e. piston shaft member A; Be trapped among the piston shaft member around, what the roughly the same full cycloid gear ring of its shape had n+1 jog is exactly cylinder circle member 2; Piston shaft member and cylinder circle member are bearing in the supporting 3-1 of casing body member 3 respectively; On the 3-2, and respectively with O

2-O
2Be shaft axis, together with the rotation of making equidirectional constant speed ratio together is " together with changeing ", if observe from mechanically operated angle, the mechanism of dead axle full cycloid tooth wheel set mechanism and Fig. 1 to 2 expression is quite similar as can be seen, but this is strange, because the latter transforms development and comes from the former just; Referring again to Fig. 3 to 4, engine mechanism shown in the figure, with mechanism shown in Fig. 1 to 2 with in have again also, its rotary-piston and arbor separate, be two kinds of members, and its arbor is an an eccentric shaft (or bent axle, member 4 down together), revolution when piston component 1 is just done rotation on the eccentric journal 4-1 of eccentric shaft member 4, in other words, piston component is done the turnover motion, 2 in its cylinder and casing body 3 fuse, and to become a member be cylinder block member B, and it has the function of cylinder casing and frame concurrently, if from mechanical driving angle observation, also as can be seen, this mechanism transforms development from the full cycloid tooth wheel set of planet mechanism.Just because of this, mechanism as herein described is still keeping the good drive characteristic and the function of dead axle or the full cycloid tooth wheel set of planet mechanism aspect transmission, and this task of finishing its engine mechanism aspect for them is absolutely necessary with very useful, and this can see clearlyer later.In sum, rotary piston type engine mechanism of the present invention has together with transition, and also have epicyclic-type: rotary-piston type is characterized in that together with the engine mechanism of transition the full cycloid tooth wheel set of dead axle poor by a tooth, interior engagement mechanism transforms development; Its piston and arbor are fixedly to fuse, composition " piston shaft " member A's, this member is made dead axle by 3 of the casing body members that has the frame function concurrently and is rotatablely moved; Its cylinder member 2 is round and also rotates, and is also rotatablely moved as dead axle together with the piston shaft member by the casing body member supporting; The shaft axis of its piston shaft and cylinder circle two members is parallel to each other; Rotary-piston type epicyclic-type engine mechanism is characterized in that the full cycloid tooth wheel set of planet poor by a tooth, interior engagement mechanism transforms development; Its arbor is an eccentric shaft member 4; It is that piston component is to do the turnover motion that its piston component 1 rotates on the eccentric journal 4-1 of eccentric shaft member 4; Its cylinder is to become the cylinder block member B that has the frame function simultaneously concurrently with the casing integrator; The main axis of its eccentric shaft is coaxial with cylinder axis.
Full cycloid, full cycloidal gear and gear pair mechanism all are that China finds at twentieth century, invention, full cycloid technology is the independent intellectual property right of China's initiative.The technological know-how of relevant full cycloid transmission, nineteen ninety-five, we were open on the patent documentation of " cycloid gear transmission mechanism and device thereof ", (ZL.95105885.1).Because further having transformed full cycloid gear transmission mechanism to develop into, the present invention produces the new mechanism that power is used, therefore, this paper except the full cycloid tooth wheel set relevant knowledge of engagement in the tooth difference is selected to introduce a little, emphasis is the explanation performance of this mechanism aspect power.We prove that already the full cycloid tooth wheel set of engagement in the tooth difference can realize the contact of whole teeth: if the small gear number of teeth is n, the gear ring number of teeth is n+1, (annotate: n can be the arbitrary integer more than or equal to 2) then the contact of gear pair to count be n+1 to n+2.P1 to P5 represents each point of contact of gear pair among (referring to Fig. 5 to 8) figure.
The working surface of engine mechanism of the present invention and device (referring to Fig. 9 to 12) is the full cycloidal cylinder that a secondary conjugation is nibbled mutually, and it meshes the full cycloid straight-tooth flank of tooth roughly the same with a tooth difference is interior, and its active chamber then is to transform development by the allowance between tooth and the tooth.Obviously, the branch chamber line of its active chamber is converted by the point of contact of gear pair, and therefore, according to the preamble introduction as can be known: if power engine piston protuberance is n, when cylinder circle recess was n+1, then its active chamber number also was n+1.V1 to V5 represents not isometric each active chamber among (annotate: the position that has can be n+2 in theory, but this moment, n+2 active chamber was minimum) figure.The working principle of rotary piston type engine groundwork mechanism
Rotary piston type engine and reciprocating type machine significant difference are that its active chamber is that end section by rotary-piston is the axial cylinder of full cycloidal, and the end section of cylinder is that the axial cylinder of full cycloidal and the inner end flat in front and back of casing or casing housing surround.In static relatively or when rotation, the n on the piston convex-concave portion surface all the time with cylinder in n+1 jog surface be in contact with one another the n+1 place, thereby piston is become n+1 active chamber with separated by spaces between the cylinder.Situation during its work: together with the transition power engine (seeing Figure 13 to 18), when piston shaft and cylinder circle such as figure begin to rotate in the same way from the top, each active chamber sectional area in its place ahead increases from top to bottom gradually, reach maximum during to the below, reach minimum when being reduced to the top then from bottom to top gradually.Changeed a week and work as piston shaft, recess in front that its piston protuberance just enters into the cylinder circle has gone.At epicyclic-type power engine (seeing Figure 19 to 26), its cylinder block is motionless, when piston rotates.Its eccentric shaft is made counter-rotation, the piston protuberance is from beginning to enter the cylinder recess to withdrawing from the cylinder recess, the active chamber sectional area that is proportional to working chamber volume is also got back to maximum again by being up to minimum, when a back by the time piston protuberance entered the position that previous piston protuberance begins, eccentric shaft had just in time reversed a week.S among the figure
1Extremely
The instantaneous cross section that changes in order of expression active chamber.
On working principle, as the active chamber of piston internal-combustion power engine work mechanism, the most important work cycle requirement that must satisfy its worker's Jie material exactly is as the requirement of the air inlet of internal-combustion engine, compression, burning expansion, exhaust; External combustion piston type machine also has the work cycle requirement of air inlet, expansion, exhaust and compression; Therefore, with the corresponding active chamber sectional area of working chamber volume, must change to largest loop ground by minimum with the period of rotation ground of power engine main shaft.Obviously, previously described cylinder can both satisfy the requirement of above-mentioned work cycle together with the active chamber of transition or piston epicyclic-type power engine very goodly.● the present invention compared with the prior art: 1, power engine work mechanism and device have unprecedented simple advantage
The reciprocating type machine of prior art for example, need five kinds of main members: it is cylinder block that casing body adds cylinder, piston, wrist pin, connecting rod, bent axle; Wherein, cylinder and piston component are as producing power; Piston, wrist pin, connecting rod, the bent axle member is as becoming to-and-fro motion into rotatablely moving and transferring power, power engine of the present invention only needs three kinds of main members, and for example three kinds of members together with the machine of transition are: casing body, the cylinder circle, piston shaft, producing power still is that transferring power is all used them; When worker's Jie material is done the time spent, under for example fuel gas buring expands and promotes,, just can directly rotate motion and produce power only with cylinder circle and piston shaft one submember; With power, moment, the approach of transmission of power and transmission link all shorten has significantly simplified.And for example the groundwork member of the triangle piston formula motor of prior art has: cylinder block adds gear, triangle piston adds gear ring, eccentric shaft, look that slightly as if member also has only three kinds, but in fact want it to run well and generation power, these two kinds of parts of gear and gear ring are absolutely necessary, in epicyclic-type power engine of the present invention, its main member is: cylinder block, piston, eccentric shaft, not only really have only three kinds, and under the gaseous-pressure effect, its piston can produce the turnover motion voluntarily in the cylinder circle, and the promotion eccentric shaft rotates.See Figure 19 to 26, can not have enough to meet the need voluntarily with triangle piston and leave no choice but outerly add that gear pair is push-jump to be compared that obvious operation mechanism of the present invention is better function not only, and much more simple and reliable.2, full cycloid active chamber has multiple characteristics and advantage
(a) full cycloidal cylinder active chamber of the present invention can obtain relatively large swept volume in less space; Reason be n+1 active chamber (n for more than or equal to 2 than small integer) uniform on circumference, one sub-piston cylinder just is equivalent to one whole star multi-cylinder engine, if there is throw of eccentric identical again, all be e, then the active chamber length of prior art is 2e, and full cycloid active chamber length is 4e (referring to Figure 16) and can reduces because of establishing the space that connecting rod accounts for more.This has just improved utilization of space, can be so that the structure of power engine of the present invention is quite compact.
(b) area of this active chamber is from being up to minimum, and it changes greatly, so can obtain big compression ratio; For example during four recesses of cylinder, can be regarded as its theoretical area ratio can reach 1 (this is than the big manyfold of triangle piston formula machine) more than 288 times thus provide advantage for improving engine efficiency, can also be used on the diesel engine one class compression ignite h type engine h.
(c) this active chamber is more wear-resistant, also sealing easily; Aspect the friction in active chamber, the piston of reciprocating type machine and the friction of cylinder all are sliding frictions; The piston of triangle piston formula machine and the friction between cylinder also are sliding friction basically and concentrate on the part, therefore be easy to wear and tear in three bights of piston and make the wavy bar shaped wearing and tearing of generation on the cylinder wall, cause gas leakage,, also be difficult for resolving the problem in sealing and life-span even adopt Stamping Steel Ribbon; The then existing rolling friction of friction in the active chamber of the present invention between cylinder and the working surface of piston has sliding friction again, and the load big position be based on rolling friction; Have again with triangle piston formula machine in itself difference be, every bit on the full cycloid active chamber face all participates in working procedure, be the contact of pointwise conjugation, this has quite big effect to improving wear resistance and sealing, has also created good condition for prolonging operating life.
3, the beneficial effect that aspect balance, has
Of the present invention together with power engine transition, owing to cylinder circle and rotary piston shaft all are in from the state that balances each other to its rotating shaft from design of part, and be rotatablely moving of dead axle, it is obviously much easier than reciprocating type machine to solve equilibrium problem; In the epicyclic-type machine, owing to deducted a secondary internal gear pair, no matter be single counterweight setting, or solve the static balancing dynamic equilibrium problems with double three row's formula symmetric arrangement than triangle piston formula machine, also all simple many.
In addition, the distribution of power engine of the present invention part also can be easy to be provided with and simplify to some extent than prior art.The distribution of power engine partly is to cooperate power engine groundwork mechanism controls fresh combustion gases and waste gas, makes it to enter and discharge by certain hour in the course of the work, and it also is that power engine produces the indispensable part of power realization proper functioning continuously.Because after the groundwork mechanism simplifying of power engine of the present invention, the position relation of working procedure and arbor is more direct, and locate all can have the position that distribution (and igniting, oil spout etc.) part is set in cylinder periphery and both sides end face etc., this has just partly created good condition for simplifying distribution etc.Relevant power engine distribution part of the present invention position additional disclosure in an embodiment is set etc.
In sum, compared with the prior art, power engine of the present invention has parts few, and is simple and reliable for structure, and volume is little, and is in light weight, and rotating speed is can be quite high and vibrate for a short time, and therefore the advantage of many aspect of performances such as it is steady turn round has the value of application and development popularization very much.
