Radiale Kolbenmotor Arbeitsprinzip

Ngoba kunezinhlobo ezimbili eziyinhloko zamamotho e-radial piston, okungukuthi, i-single acting ne-multi acting, izimiso zazo zokusebenza zethulwa kulokhu okulandelayo.

(1) Isebenza ngendlela ye-single acting radial piston motor Njengoba kuboniswe kuMfanekiso o, ama-silinda amahlanu (noma ayisixhenxe) ahlelwe ngokuqondile futhi ngokulinganayo emaphethelweni e-housing 1. I-plunger 2 esilindeni ixhunywe ne-connecting rod 3 nge-ball hinge, futhi ukuphela kwe-connecting rod kuhlangana ne-ehcetric wheel ye-crankshaft 4 (isikhungo se-ehcetric wheel ngu-O1, isikhungo sokujikeleza se-crankshaft ngu-O, futhi i-eccentricity yazo zombili ngu-e). Umphetho owodwa we-crankshaft ungumshini ophumayo, kanti omunye umphetho uxhunywe nge-cross coupling ne-valve distribution shaft 5. Izinhlangothi ezimbili ze-partition wall ku-valve distribution shaft ziyi-oil inlet chamber kanye ne-oil discharge chamber ngokulandelana.

Potlako ya oli e tsoang mehloling ya oli e kena ka kamoreng ya oli ya motlakase, e kenngwa ka siling (1), siling (2) le siling (3) tsa borai. Matla a hydraulic P a hlahisoang ke oli e phahameng a sebetsa holim'a hlooho ea plunger 'me a fetisetsoa ho eccentric ea crankshaft ka borai. Mohlala, matla a sebetsang ho eccentric ka piston cylinder ② ke n, 'me tsela ea matla e latela mola o bohareng oa borai 'me e lebisa ho bohareng O1 ba eccentric. Matla n a ka aroloa ka matla a tloaelehileng FF (mola o sebetsang o lumellana le khokahano 001) le matla a tangential F. Matla a tangential F a hlahisa torque ho potoloho ea 0 ea crankshaft, e etsang hore crankshaft e potolohe ka ho le letona ho potoloha mola o bohareng 0. Piston cylinder (1) le (3) li tšoana le sena, ntle le hore boemo ba tsona bo amanang le spindle bo fapane, ka hona torque e hlahisoang e fapane le ea siling (2). Torque e akaretsang ea potoloho ea crankshaft e lekana le kakaretso ea torque e hlahisoang ke piston cylinder e amanang le kamore e phahameng (①, ② le ③ ka mohlala o). Ha crankshaft e potoloha, mekhahlelo ea siling ①, ② le ③ e eketseha, ha mekhahlelo ea siling ④ le ⑤ e fokotseha, 'me oli e qhibilihisoa ka tsela ea oli ea shell ④ le ⑤ ka kamoreng ea oli ea port shaft 5.

Wanneer die klepverdelingas en die krukas sinchronies vir 'n hoek draai, sluit die "afdeling muur" van die klepverdelingas die oliegang (3). Op hierdie tydstip is die silinder (3) nie verbind met die hoë en lae druk kamers nie. Silinders (1) en (2) word voorsien van hoë druk olie, wat die motor in staat stel om torsie te produseer, en silinders (4) en (5) stoot olie uit. Soos die klepverdelingas saam met die krukas draai, word die olie-inlaatkamer en die olie-uitlaatkamer onderskeidelik met elke plunjer in beurt verbind, sodat die deurlopende draai van die krukas verseker kan word. In een omwenteling, beweeg elke plunjer die olie een keer in en uit. Die werksbeginsel van ander enkelwerkende motors is soortgelyk aan hierdie.

The working principle of single acting radial piston motor should pay attention to the following points.

① I-motor ingaguva ngokushintsha umoya ophumayo nowokufaka we-motor. Uma i-ecentric ring ihlukaniswe ne-output shaft ye-motor futhi kuthathwa izinyathelo zokwenza ibanga le-ecentric likwazi ukulungiswa, inhloso yokushintsha ukuhamba kwe-motor ingafezwa, futhi i-motor yokuhamba okushintshashintshayo yenziwa.

② Die in Abbildung o gezeigte Motor ist gehäusefest, daher wird er auch als Wellenmotor bezeichnet; wenn die Kurbelwelle fest ist, kann er zu einem Gehäusemotor gemacht werden. Der Gehäusemotor ist besonders geeignet für die Installation in der Winden-Trommel oder auf der Radnabe des Fahrzeugs, um direkt das Rad anzutreiben und zum Radmotor zu werden.

③ I-motor oboniswa ku-Figure o ye-distribution pair iyisikhala se-axial distribution. Ngoba ohlangothini olulodwa lwe-valve shaft kukhona i-cavity ye-high-pressure kanti ohlangothini olunye kukhona i-cavity ye-low-pressure, inqubo yokusebenza ye-valve shaft ibhekene nomthwalo omkhulu we-radial, okwenza i-valve shaft ihanjiswe ohlangothini olulodwa futhi kwandise umgomo ohlangothini olunye, kuholele ekuguguleni kwesikhala esihambayo nokwandiswa kokuvuza, kuholele ekwehleni kokusebenza. Ngalesi sizathu, kuvame ukwamukelwa ukusetha i-symmetrical balancing oil groove ukuze kulungiswe umthwalo we-radial. Njengoba kuboniswe ku-Figure P, i-static pressure balance valve distribution shaft ivaliwe ngeringi yokuvikela. I-central C-C window hole iyindawo yokusabalalisa i-valve, ama-grooves anjenge-annular ku-B-B no-D-D angama-oil inlet kanye ne-oil return window holes ngokulandelana, kanti i-A-A no-E-E ama-grooves e-semicircular annular ye-static pressure balance. Kucabanga ukuthi ama-sealing rings abekwe ngokuhambisana nendawo ye-sealing belt. Uma umkhondo we-oil inlet kanye ne-outlet uboniswa njengokukhombiswa yithuluzi ku-Figure P, izikhala ezibhalwe uphawu P zingama-chambers e-high-pressure, kanti izikhala ezibhalwe uphawu T zingama-chambers e-low-pressure. Kungabonakala ukuthi ama-circumferential pressures e-B-B no-D-D afana, futhi awekho umthwalo we-radial; i-chamber ephezulu ye-C-C window hole section ixhunywe ne-oil inlet, okuyindawo ye-high pressure, kanti i-chamber ephansi ixhunywe ne-oil return port, okuyindawo ye-low pressure, ngakho i-valve distribution shaft ibhekene nomthwalo omkhulu we-radial. Ukuze kulungiswe umthwalo we-radial, ama-semicircular annular balancing oil grooves A-A no-E-E asetshenziswa eziphethweni zombili ze-valve distribution shaft ukuze kuqinisekiswe ukuthi i-cavity ephezulu igcwele i-high pressure oil. Ukuze kuncishiswe ukuvuza, ama-sealing rings asetshenziswa phakathi kwezakhi. Ukuze kuqinisekiswe i-static pressure balance yezinhlangothi eziphezulu nezisezansi, usayizi ofanele we-oil distribution window kanye ne-balance oil groove kufanele uhambisane nale mfuneko elandelayo:

a+e=2(b+c)                      (5-4)

Where a -- width of flow distribution window;

B -- ububanzi bokufaka ibhande le-balance oil tank;

C -- ububanzi bebhakede le-oyili elilinganayo;

E -- die Breite des Dichtungsbands des Flussverteilungsfensters.

Ngoba amandla e-radial alinganisiwe, amandla okuxhaphaza ancane kakhulu, okwenza kube ngcono ukusebenza kwemishini. Ngasikhathi sinye, ukuhamba kwe-radial phakathi kwe-valve shaft ne-valve sleeve kuncishisiwe, uku leak kuncishisiwe, futhi ukusebenza kwe-volumetric kuthuthukisiwe. Endaweni yokusebenza ejwayelekile, ukusebenza okuphelele kukhulu phakathi kuka-85% no-90%.

Figure Q shows the end face flow distribution structure of the crankshaft connecting rod hydraulic motor. The crankshaft 13 drives the port plate 4 and the pressure plate 2 to rotate synchronously through the square head 12, and the port is realized during the rotation. During start-up or no-load operation, the backup spring (disc spring) 3 makes the valve plate and pressure plate close to the cylinder block 11 and the end cover. The design ensures that the close force is greater than the separation force between the valve plate and the cylinder block, and the hydraulic pressure realizes the close force during operation. However, due to the non coincidence of separation force and sticking force, the valve plate has tilting moment. By using the static pressure balance structure design, the end face port pair can achieve complete balance in theory.

Kufanele kukhunjulwe ukuthi ukuze kuthuthukiswe ukwethembeka nokusebenza komshini we-hydraulic futhi kwenze isakhiwo sibe sikhulu, enye yezitayela zokuthuthukiswa ekhaya nasezwenikazi yikusebenzisa iphaneli yokugcina.

④ Ngaphezu kokuhlanganiswa kwezimoto, ukusebenza kwe-crankshaft connecting rod hydraulic motor kuncike kakhulu ekwenzeni kwe-connecting rod motion pair. Isakhiwo esijwayelekile se-connecting rod ball joint pair sikhonjiswa kuMfanekiso R. Siqukethe ama-pair amabili e-friction pairs, ikhanda le-ball le-connecting rod 4 kanye ne-ball socket ye-plunger 2, phansi kwe-connecting rod slider 5 kanye ne-crankshaft (eccentric wheel) 6. Ukuxhumana kwensimbi phakathi kwephansi kwe-connecting rod slider kanye ne-crankshaft (eccentric wheel) bekukwi-early stage, futhi i-alloy evikela ukugqoka yakhazinywa phansi kwe-slider ukuze kuncishiswe ukuxhumana. Ezinye i-crankshafts zezimoto (eccentric wheels) zifakwe ama-roller bearings, asebenzisa ukuxhumana kokugudluza ukuze athathe indawo yokuxhumana kokuhamba phakathi kwephansi kwe-slider kanye ne-eccentric wheel; okwamanje, iningi lezimoto liklanyelwe njenge-hydrostatic balance noma i-hydrostatic support. Igumbi le-oli limisiwe phansi kwe-slider, futhi i-oli enezinga lok pressure ingena egumbini le-oli eliphansi nge-damper emaphakathi kwe-connecting rod. I-sliding block ayifloyidi ngesikhathi sokusebenza, ingcindezi ye-oli egumbini ibalanced iningi le-plunger thrust, futhi i-friction pair ihlanzekile kahle.

Shiya imininingwane yakho futhi
sizokuthinta.
