Rotacijski batni strojRotary piston machine

Izum se nanaša na rotacijski batni stroj. Predmet izuma se da uvrstiti v razred F 01 C 1/00Int. Cl.⁵ The invention relates to a rotary piston machine. The subject matter of the invention can be classified in class F 01 C 1 / 00Int. Cl. ⁵

Znani batni stroji delujejo na principu spreminjanja vrtilnega v premočrtno izmenično gibanje ali obratno. Pri delovanju takšnega stroja se smer premočrtno gibajočega se bata ali batov ciklično spreminja, kar se odraža v sorazmerno velikih hitrostnih in pospeškovnih spremembah. Posledica takšnega neenakomernega gibanja bata/batov so sorazmerno velike sile in momenti, ki delujejo na bat/bate in na batni stroj sam.Known reciprocating pistons operate on the principle of rotational rotation in a straight or alternating motion. In the operation of such a machine, the direction of the reciprocating piston or pistons changes cyclically, resulting in relatively large velocity and acceleration changes. Such uneven piston / piston movement results in relatively large forces and moments acting on the piston / piston and on the piston machine itself.

Navedene probleme se je poskušalo rešiti z novo konstrukcijo batnega stroja, zlasti rotacijskega batnega stroja, tj. stroja z vrtljivim batom. Pri tem je znan ti. Wankel motor, ki je zasnovan kot epitrohoidni stroj z batom, pri čemer je bat v bistvu zasnovan kot trikotnik z izbočenimi stranicami. Kljub manjšemu številu sestavnih delov (ventilov npr. ni) je pomanjkljivost tovrstnega stroja v primerjavi s strojem s premočrtno izmenično gibajočim se batom zahtevna izdelava konture delovnega prostora in pomanjkljivo tesnjenje bata. Navedeni stroj tako kljub prednostim glede izravnave mas, vgradnega volumna in mase ni prosperiral.The above problems were tried to be solved by the new design of the piston machine, in particular the rotary piston machine, ie. machine with rotary piston. In this, you are known. Wankel motor designed as an epitrochoid piston machine, the piston being essentially designed as a triangle with convex sides. Despite the small number of components (eg there are no valves), the disadvantage of this type of machine, compared to a machine with a linearly rotating piston, is the demanding construction of the contour of the workspace and the lack of sealing of the piston. In spite of its advantages in terms of weight balancing, installation volume and mass, the said machine did not prosper.

Izhajajoč iz zgoraj navedenih pomanjkljivosti je predmet izuma zasnovan na problemu, kako zasnovati delovni ali pogonski rotacijski batni stroj, katerega tesnjenje je zanesljivo, katerega gibajoče se mase so dinamično ugodno razporejene, ki je s stališča števila sestavnih delov enostaven za izdelavo ter cenovno ugoden, in katerega delovanje je okolju prijazno.Based on the above disadvantages, the object of the invention is based on the problem of how to design a working or propulsion rotary piston machine whose sealing is reliable, whose moving masses are dynamically positioned, which is easy to manufacture and affordable in terms of number of components, and whose operation is environmentally friendly.

Zastavljeni problem je po izumu rešen tako, da je v ohišju relativno glede na slednjega drsno pomično razporejen par batov, ki z luknjama, v katerih drsita, tvorita ohlapni ujem. Pri tem je par batov preko ročic povezan z votlo odgonsko gredjo, v kateri je istoosno s slednjo z ohlapnim ujemom razporejena nadaljnja odgonska gred, V slednji je istoosno zasnovana izvrtina, pri čemer je na prostem koncu prve odgonske gredi rotacijsko togo razporejeno prvo eliptično zobato kolo, na prostem koncu gredi z izvrtino pa nadaljnje eliptično zobato kolo. Eliptični zobati kolesi sta v prijemu z izsredno na odgonski gredi v zobniškem predležju razporejenima zobatima kolesoma.The problem according to the invention is solved in such a way that a pair of pistons are slidably disposed in the housing relative to the latter, forming a loose catch with the holes in which it slides. In this case, a pair of pistons is connected via a lever to a hollow output shaft, in which a further output shaft is arranged parallel to the latter with a loose match. In the latter, a bore is formed, with the first elliptical gear wheel rotatably arranged at the free end of the first output shaft. and at the free end of the shaft with a bore a further elliptical gear wheel. The elliptical toothed wheels are arranged with the toothed wheels in the grip with the toothed shaft in the gear area.

Pri tem sta eliptični zobati kolesi v ravnini vrtenja drugo proti drugemu zamaknjeni za tt/2 rad. Izsrednost obeh izsrednih zobatih koles je v ravnini vrtenja druga proti drugi zamaknjena za tt rad. Vsakokratni eliptični zobati kolesi oz. izsredni zobati kolesi sta prednostno enakih izmer.In doing so, the elliptic gear wheels are offset by tt / 2 rads in the plane of rotation. The axiality of the two serrated gears is offset by tt rad in the plane of rotation. The respective elliptical gear wheels respectively. Extraordinary gear wheels are preferably of equal dimensions.

Nadaljnja značilnost stroja po izumu leži v tem, da je ročica z votlo odgonsko gredjo v togi povezavi, z batom pa je zgibno povezana preko polznika, ki je v utoru bata drsno pomičen prečno glede na vsakokraten bat.A further feature of the machine according to the invention lies in the fact that the hollow output shaft arm is rigidly connected, and the piston is articulated via a slider, which is slidably slid transversely with respect to each piston.

Ohišje stroja je v vzdolžni smeri in s svojega prvega konca zasnovano s soosno potekajočo valjasto poglobitvijo, v kateri je na po sebi znan način uležajena votla odgonska gred. Zadevna poglobitev je predvidena tudi za sprejem mazalnega olja.The housing of the machine is designed in the longitudinal direction and from its first end by a coaxially extending cylindrical recess in which a hollow output shaft is mounted in a known manner. The recess in question is also intended for the reception of lubricating oil.

Valjasto, v radialni smeri intenzivnejše ohišje stroja je sestavljeno iz dveh enakih polovic, pri čemer leži delilna ravnina (X) v prečni osi ohišja, vsakokratna polovica ohišja pa je prečno glede na vzdolžno - sistemsko os stroja zasnovana s skoznjo luknjo okroglega prečnega prereza, potekajočo vzporedno z delilno ravnino (X) ohišja. Ti luknji prednostno potekata medsebojno vzporedno in na enakem odmiku od vzdolžne osi stroja.The cylindrical, intensely intensified machine body consists of two equal halves, the dividing plane (X) in the transverse axis of the housing, and each half of the housing being transverse with respect to the longitudinal - system axis of the machine through a circular cross-sectional hole running through parallel to the dividing plane (X) of the housing. These holes preferably run parallel to each other and at the same distance from the longitudinal axis of the machine.

Pri tem je vsakokratna luknja skoncema zaprta s kapo, pri čemer sta na isti strani ležeči kapi središčno glede na skoznjo luknjo zasnovani z navojno skoznjo luknjo za namestitev vžigalne svečke.In each case, the end hole is closed by a cap, with the caps located on the same side centrally with respect to the through hole being designed with a threaded through hole to accommodate the spark plug.

Nadaljnja značilnost stroja po izumu leži tudi v tem, daje dovod zmesi gorivo/zrak izveden skozi izvrtino v gredi, prečni skoznji luknji v tej gredi in dovodni kanal v vmesno komoro in preko pretočnega kanala naprej v delovno komoro batnega stroja. Izpuh plinov pa je izveden skozi izstopni kanal v hlačasto cev, ki je na ohišje priključena centrično glede na vzdolžno os stroja.A further feature of the machine according to the invention also lies in the fact that the inlet of the fuel / air mixture is made through a bore in the shaft, a transverse through hole in that shaft, and a supply channel to the intermediate chamber and through the flow channel to the working chamber of the piston machine. Exhaust gas, however, is carried out through the outlet duct into a trouser tube which is centrally connected to the housing with respect to the longitudinal axis of the machine.

Prosti konec votle gredi 7, ki je uležajen v steni 10 zobniškega predležja 11, štrli v ohišje samo omenjenega zobniškega predležja, pri čemer je na tem prostem koncu rotacijsko togo in centrično razporejeno prvo pogonsko eliptično zobato kolo 22. To zobato kolo 22 je v prijemu z izsredno na odgonski gredi 23 razporejenim prvim odgonskim valjastim zobatim kolesom 24. Na odmiku od slednjega je na gredi 23 in prav tako izsredno glede na slednjo razporejeno drugo valjasto odgonsko zobato kolo 25, ki je v prijemu z drugim pogonskim eliptičnim zobatim kolesom 26. Tudi to je, tako kot prvo eliptično zobato kolo 22, razporejeno centrično na gredi 8, štrleči v ohišje zobniškega predležja 11 in uležajeni v drugi steni 12 slednjega. Pri tem je eliptično zobato kolo 26 glede na eliptično zobato kolo 22 v ravnini vrtenja zamaknjeno za ττ/2 rad, izsrednost valjastih zobatih koles 24, 25 pa je glede na ravnino vrtenja zamaknjena za π rad. Odgonska gred 23 štrli iz ohišja predležja 11, pri čemer je predvidena za odjem vrtilnega momenta. Vsa zobata kolesa so na svojih gredeh pritrjena rotacijsko togo.The free end of the hollow shaft 7, which is mounted in the wall 10 of the sprocket 11, protrudes into the housing only of the said sprocket, with a rotary rigid and centrally arranged first drive elliptical gear wheel 22 disposed at this free end 22. This gear wheel 22 is in the grip having a first cylindrical gear wheel 24 disposed on the output shaft 23, at a distance from the latter, there is also a second cylindrical gear wheel 25 disposed in relation to the latter, which is in engagement with the second drive elliptical gear wheel 26.

Mazanje stroja se izvaja z oljno kopeljo, pri čemer se olje nahaja v prostoru, ki ga tvorijo poglobitev 6 in kanala 13a, 13b. Iztekanje olja preprečujeta po sebi znana zaprta ležaja.Lubrication of the machine is carried out with an oil bath, the oil being located in a space formed by the recess 6 and channels 13a, 13b. The leakage of the oil is prevented by the known sealed bearings.

Rotacijski batni stroj po izumu deluje npr. kot dvotaktni motor z notranjim zgorevanjem na naslednji način.The rotary piston machine according to the invention operates e.g. as a two-stroke internal combustion engine as follows.

Privzemimo, da je začetni položaj npr. bata 4b takšen, kot je prikazan na sl. 3, tj. v ZML. V tem trenutku neprikazana vžigalna svečka vžge gorivo v zgorevalni komori, pri čemer nastali tlak potisne bat 4b navzdol. Slednji pri svojem gibanju navzdol zapre dovodni kanal 18b za gorivo in prične stiskati v vmesni komori nahajajočo se zmes gorivo/zrak. Ker bat 4b pri tem še zapira vstop pretočnega kanala 19b v zgorevalno komoro, se tlak zmesi v vmesni komori povečuje. Ko se bat 4b pomika proti SML v določenem trenutku sprosti izstopni kanal 20b, s čimer se omogoči, da plini zapustijo zgorevalno komoro. Pri nadaljnjem spuščanju bata 4b proti SML se sprosti vstop kanala 19b v delovno komoro, pri čemer stisnjena zmes gorivo/zrak vdre v delovno komoro in dodatno pomaga pri izpihu plinov. Ko bat 4b doseže SML, pri čemer je njegova Čelna ploskev na delovni strani v bistvu poravnana s spodnjim robom vstopnega ustja kanala 19b, je celotna količina zmesi gorivo/zrak potisnjena v zgorevalno komoro. Bat 4b se prične gibati navzgor in ko popolnoma zapre izstopni kanal 20b, stiska zmes gorivo/zrak v delovni komori. V vmesni komori nastaja pri tem podtlak, ki v trenutku, ko bat 4b sprosti vstop kanala 18b v vmesno komoro, posesa zmes gorivo/zrak, ki doteka po izvrtini 9 gredi 8 in skozi skoznjo luknjo 17 po kanalu 18b. Ko je dosežena ZML, vžigalna svečka ponovno vžge zmes in proces se ponovi.Assume that the starting position, e.g. piston 4b as shown in FIG. 3, ie. in ZML. At this point, a non-displayed spark plug ignites the fuel in the combustion chamber, with the resulting pressure pushing the piston 4b down. The latter, when moving downward, closes the fuel inlet duct 18b and begins compressing the fuel / air mixture present in the intermediate chamber. As the piston 4b further closes the inlet of the flow channel 19b into the combustion chamber, the pressure of the mixture in the intermediate chamber increases. When the piston 4b moves towards the SML at some point it releases the outlet channel 20b, allowing the gases to leave the combustion chamber. Further lowering of piston 4b toward the SML releases channel 19b into the work chamber, whereby the compressed fuel / air mixture enters the work chamber and further aids in the exhaust gas. When the piston 4b reaches the SML, with its front face substantially aligned with the lower edge of the inlet mouth of the channel 19b, the total amount of the fuel / air mixture is pushed into the combustion chamber. The piston 4b begins to move upwards and, when it completely closes the outlet duct 20b, compresses the fuel / air mixture in the work chamber. In the intermediate chamber, a pressure is generated which, at the moment when the piston 4b releases the inlet of the channel 18b into the intermediate chamber, sucks in the fuel / air mixture which flows through the bore 9 of the shaft 8 and through the hole 17 through the channel 18b. When ZML is reached, the spark plug re-ignites the mixture and the process is repeated.

Bata 4a, 4b delujeta zamaknjeno za en takt. Ko je pri prvem stiskanje oz. ekspanzija, je pri drugem sesanje oz. pretakanje zmesi gorivo/zrak iz vmesne v delovno komoro.Pistons 4a, 4b operate offset by one stroke. When the first is compression or. expansion, is the second suction or. the flow of the fuel / air mixture from the intermediate to the working chamber.

Izumiteljska zamisel rotacijskega gibanja pa je naslednja.The inventive idea of rotational motion, however, is as follows.

Z zavrtitvijo gredi 8 se zavrti tudi ohišje 1, s katerim je v togi zvezi. Pri tem pa se zavrti tudi eliptično zobato kolo 26, ki pri položaju po sl. 4 prenese vrtilno gibanje preko izsrednih zobatih koles 25 in 24 na eliptično zobato kolo 22. Zaradi razlike v trenutnih polmerih zobatih koles 22 in 26 se gred 7 vrti bistveno hitreje kot gred 8. Zaradi razlike hitrosti vrtenja med ohišjem 1 in gredjo 7, ki je preko ročic 14a, 14b v delovni zvezi z batoma 4a, 4b, pride do relativnega translatomega gibanja batov 4a, 4b glede na ohišje 1, pri čemer eden od batov izvaja npr. sesanje, drugi pa stiskanje zmesi gorivo/zrak. Pri tem se eliptični zobati kolesi 22, 26 zavrtita za π/2 rad, v zgorevalni komori drugega bata pride do vžiga, kar pospeši gibanje tega drugega bata proti SML. Pri tem se gred 7 zavrti hitreje od gredi 8, vendar je hitrost na odgonski gredi 23 enaka zaradi prenosa vrtilnega momenta preko eliptičnih zobatih koles 22, 26, ki imata v vsakem trenutku s ciklom π rad, usklajeno s takti batov, drugačen premer. Ohišje 1 deluje pri tem kot vztrajnik.By rotating the shaft 8, the housing 1 is also rotated, with which it is rigidly connected. In doing so, an elliptical gear wheel 26 is also rotated, which at the position of FIG. 4 transfers the rotational motion through the extra gears 25 and 24 to the elliptical gear 22. Due to the difference in the current radii of the gears 22 and 26, the shaft 7 rotates much faster than the shaft 8. Due to the difference in rotation speed between the housing 1 and the shaft 7, which is through the arms 14a, 14b in working relation to the pistons 4a, 4b, relative translatome movement of the pistons 4a, 4b relative to the housing 1 occurs, with one of the pistons performing e.g. suction and the other by compressing the fuel / air mixture. The elliptic gear wheels 22, 26 rotate by π / 2 rad, ignition occurs in the second piston combustion chamber, which accelerates the movement of that second piston against the SML. In this case, the shaft 7 rotates faster than the shaft 8, but the speed on the output shaft 23 is the same due to the transfer of torque through elliptic gears 22, 26, which at each moment with the cycle π rad, consistent with the piston stroke, have a different diameter. The housing 1 acts as a flywheel.
