Injini crankshaft flywheel boka zvikamu
Kutanga, crankshaft
Crankshaft ndechimwe chezvakakosha zvikamu zveinjini, basa rayo nderekumira gasi kubva kuboka rekubatanidza tsvimbo yepiston mu torque ye crankshaft uye kubuda kwekunze, mukuwedzera, crankshaft inoshandiswawo kutyaira injini yevhavha mashandiro uye zvimwe zvekubatsira (senge jenareta, mafeni, pombi dzemvura, magetsi ekufambisa pombi, nezvimwewo).
Crankshaft flywheel boka: 1- pulley; 2- crankshaft timing zino bhandi vhiri; 3- crankshaft sprocket; 4- Crankshaft; 5- crankshaft main bearing (pamusoro); 6- Flywheel; 7- Speed sensor chiratidzo jenareta; 8, 11- purasita; 9- crankshaft main bearing (pasi); 10- Crankshaft main bearing cover.
Kana iyo crankshaft ichishanda, inofanirwa kumira nguva nenguva kushanduka kwegasi, kudzoreredza inertial simba uye centrifugal simba, pamwe chete ne torque yavo nekukotama nguva iri pasi pekumhanya-mhanya, nyore kukotama uye kumonyorora deformation, saka, crankshaft inofanirwa kuve nesimba rakakwana uye kuoma, kupfeka kwakanaka kuramba uye chiyero chakanaka. Iyo crankshaft inowanzo gadzirwa nepakati kabhoni alloy simbi, uye iyo jenari pamusoro inobatwa nepamusoro-frequency kudzimwa kana nitriding. Shanghai Santana injini crankshaft yakagadzirwa nepamusoro-soro yepakati kabhoni simbi inofa yekugadzira. Iyo Audi JW uye Yuchai YC6105QC injini dzakagadzirwa nemutengo wakaderera, yakakwirira-yakasimba isingawanzo pasi pasi ductile iron ine yakanaka kupfeka kuramba.
1. Chimiro che crankshaft
Iyo crankshaft inowanzo umbwa neyekumberi kumagumo, hombe shaft mutsipa, crank, counterweight, yekubatanidza tsvimbo yejenari uye kumashure. Crank inoumbwa nejenari yetsvimbo yekubatanidza uye majenari ayo makuru ekuruboshwe nekurudyi. Huwandu hwe crank ye crankshaft hunoenderana nehuwandu uye kurongeka kwemasilinda. Iyo crankshaft yeinjini imwe silinda ine crank imwe chete; Nhamba ye crank ye crankshaft ye-in-line injini yakaenzana nenhamba yemasilinda; Huwandu hwema crank mu crankshaft ye V injini yakaenzana nehafu yenhamba yemasilinda. Iyo yekumberi-yekupedzisira shaft ye crankshaft yakashongedzerwa pulley, yenguva giya, nezvimwewo, iyo inoshandiswa kutyaira pombi yemvura uye mavharuvhu. Iyo spindle mutsipa we crankshaft inoiswa muchigaro chekutakura chemuviri wecylinder uye inoshandiswa kutsigira crankshaft. Iyo yekubatanidza tsvimbo yejenari inoshandiswa kuisa iyo yekubatanidza tsvimbo, uye crank inobatanidza main shaft jenari nejenari yedanda rekubatanidza. Kuti uenzanise simba re centrifugal kana crankshaft ichitenderera, chivharo chekuenzanisa chinopiwa pa crankshaft. Flange yekubatanidza inopihwa kumucheto kumashure kwe crankshaft yekubatanidza flywheel kune crankshaft nemabhaudhi. Kuzora rejenari yetsvimbo yekubatanidza, ndima yekuzora inodhonzwa kubva kujenari huru yeshaft kuenda kune yekubatanidza tsvimbo jenari. Iyo yakakosha crankshaft iri nyore muchimiro, yakareruka muhuremu uye yakavimbika mukushanda, uye kazhinji inotora akajeka mabhengi, ayo anoshandiswa zvakanyanya mumainjini epakati uye madiki.
2. Layout musimboti crank
Chimiro che crankshaft uye nzvimbo yakaenzana ye crank yega yega inonyanya kuenderana nenhamba yemasilinda, kurongeka kwemasilinda uye kurongeka kwecylinder yega yega. Pakuronga kutevedzana kwebasa reinjini, mitemo inotevera inofanira kuteverwa sezvinobvira:
Ita kuti mavharuvhu maviri ebasa rinoenderera mberi kure kure sezvinobvira kuderedza mutoro wekutakura kukuru, uye kudzivirira kuitika kwemavharuvhu maviri akabatanidzwa kuvhura panguva imwe chete panguva yekutora, uye chiitiko che "air grab" chinokanganisa inflation yeinjini.
(1) Iyo yekushanda yenguva Angle yehumburumbira yega yega inofanirwa kuenzana kuti ifambise kushanda zvakanaka kweinjini. Mukati me crankshaft Angle apo injini inopedzisa kutenderera kwekushanda, silinda yega yega inofanira kushanda kamwe chete. Kune injini yechina-stroke ine cylinder nhamba i, nguva yebasa Angle ndeye 720 °/i. Ndiko kuti, yega yega 720 °/i ye crankshaft inofanira kunge iine cylinder yebasa kuti ive nechokwadi chekuti injini inofamba zvakanaka.
(2) Kana iri V-mhando injini, mbiru dzekuruboshwe nekurudyi dzemasilinda dzinofanira kuchinjana basa.
3. Yakajairika yakawanda-cylinder injini crank kuronga uye kushanda kurongeka
Kurongeka kwe crankshaft uye crank ye-in-line ina-stroke injini. The work interval Angle of in-line four-cylinder four-stroke engine is 720°/4=180°, the four crank yakarongedzwa mundege imwe chete, uye injini inoshanda kutevedzana (kana ignition sequence) ndeye 1-3-4-2 kana 1-2-4-3. Iyo yekushanda cycle thrust mudziyo unowanzo shandiswa ine imwe-sided semi-circular thrust pad ine anti-friction metal layer, crankshaft main bearing ine flanging uye round thrust ring ine mafomu matatu. Iyo thrust pad ndeye semi-mhete simbi pepa ine anti-friction alloy layer kunze, iyo inoiswa mugororo remuviri kana main bearing cover. Kuti udzivise kutenderera kwepadhi yekurovera, iyo thrust pad ine bulge yakanamatira mugoro. Mamwe ma thrust pads anoshandisa 4 zvidimbu kugadzira maviri akanaka denderedzwa miganhu, uye vamwe vanoshandisa 2 zvidimbu zvemiganhu. Divi rine anti-friction simbi rinofanira kutarisana necheku crankshaft.
Zhuo Meng Shanghai Auto Co., Ltd. yakazvipira kutengesa MG&MAUXS zvikamu zvemotokari zvinogamuchirwa kutenga.
