Zvikamu zveboka re crankshaft reinjini
Chekutanga, crankshaft
Crankshaft ndeimwe yezvikamu zvakakosha zveinjini, basa rayo nderekutsungirira kumanikidzwa kwegasi kubva kuboka repiston rinobatanidza tsvimbo kuenda kutorque yecrankshaft uye kubuda kwekunze, pamusoro pezvo, crankshaft inoshandiswawo kufambisa mashandiro evharuvhu yeinjini nezvimwe zvishandiso zvekubatsira (senge majenareta, mafeni, mapombi emvura, mapombi ekufambisa simba, nzira yekuenzanisa shaft, nezvimwewo)
Boka remavhiri ekufambisa eCrankshaft: 1- pulley; 2- crankshaft timing tooth belt vhiri; 3- crankshaft sprocket; 4- Crankshaft; 5- crankshaft main bearing (kumusoro); 6- Flywheel; 7- Speed sensor signal generator; 8, 11- thrust pad; 9- crankshaft main bearing (pasi); 10- crankshaft main bearing cover.
Kana crankshaft ichishanda, inofanira kutsungirira kuchinja kwegasi nguva nenguva, simba reinertial rinodzokororwa uye simba recentrifugal, pamwe chete ne torque yavo nekukotama panguva yekushanda nekukurumidza, zviri nyore kukotama nekumonereka, saka, crankshaft inofanira kunge iine simba rakakwana uye kuomarara, kuramba kupfeka zvakanaka uye kuenzana kwakanaka. Crankshaft inowanzogadzirwa nesimbi yepakati nepakati yecarbon alloy, uye pamusoro pejournal inogadziriswa ne high-frequency quenching kana nitriding. Crankshaft yeinjini yeShanghai Santana yakagadzirwa nesimbi yepakati nepakati yecarbon die forging yepamusoro. Injini dzeAudi JW neYuchai YC6105QC dzakagadzirwa nesimbi yakaderera, ine simba guru uye kuramba kupfeka zvakanaka.
1. Maumbirwo ecrankshaft
Crankshaft inowanzo kuve nerutivi rwemberi, mutsipa mukuru weshaft, crank, chinhu chinorema, dhayari rekubatanidza tsvimbo uye mugumo wekumashure. Crank inoumbwa nedhayari rekubatanidza tsvimbo uye dhayari rayo guru rekuruboshwe nerudyi. Huwandu hwecrankshaft yecrankshaft hunoenderana nehuwandu uye kurongeka kwemasilinda. Crankshaft yeinjini imwe chete ine crank imwe chete; Huwandu hwecrankshaft yeinjini iri mumutsara hwakaenzana nehuwandu hwemasilinda; Huwandu hwecrankshaft mucrankshaft yeinjini yeV hwakaenzana nehafu yehuwandu hwemasilinda. Shaft yekumberi yecrankshaft ine pulley, timing gear, nezvimwewo, zvinoshandiswa kutyaira pombi yemvura uye vharuvhu mechanism. Mutsipa wespindle wecrankshaft wakaiswa muchigaro chikuru chebheyaringi chemuviri wesilinda uye unoshandiswa kutsigira crankshaft. Dayari rekubatanidza tsvimbo rinoshandiswa kuisa tsvimbo yekubatanidza, uye crank inobatanidza shaft journal huru nedhayari rekubatanidza tsvimbo. Kuti simba re centrifugal rienzane kana crankshaft ichitenderera, pane balance block pa crankshaft. Flange inobatanidza inopihwa kumashure kwe crankshaft kuti ibatanidze flywheel ku crankshaft nemabhaudhi. Kuti ishandise connecting rod journal, nzira yekuzora inoboorwa kubva pa main shaft journal kuenda ku connecting rod journal. Integral crankshaft iri nyore muchimiro, yakareruka muhuremu uye yakavimbika mukushanda, uye inowanzo tora mabheya asina kusimba, ayo anoshandiswa zvakanyanya mumainjini epakati nediki.
2. Nheyo yekurongeka kwecrank
Chimiro checrankshaft nenzvimbo yecrank yega yega zvinoenderana nehuwandu hwemasirinda, kurongeka kwemasirinda uye kurongeka kwebasa resirinda yega yega. Pakuronga kurongeka kwebasa reinjini, mitemo inotevera inofanira kuteverwa zvakanyanya sezvinobvira:
Ita kuti ma cylinders maviri arambe achishanda kure zvakanyanya sezvinobvira kuti uderedze mutoro we main bearing, uye kudzivirira kuitika kwemavharuvhu maviri akabatana achivhurika panguva imwe chete panguva yekudya, uye chiitiko che "air grab" chinokanganisa kushanda zvakanaka kweinjini.
(1) Nguva yekushanda Angle yecylinder yega yega inofanira kuenzana kuti injini ishande zvakanaka. Mukati meAngle yecrankshaft iyo injini inopedzisa kutenderera kwekushanda, cylinder yega yega inofanira kushanda kamwe chete. Kune injini ine mastroke mana ine cylinder nhamba i, nguva yekushanda Angle i720°/i. Kureva kuti, 720°/i yega yega yecrankshaft inofanira kunge iine cylinder yekushanda kuti ive nechokwadi chekuti injini inofamba zvakanaka.
(2) Kana iri injini yerudzi rweV, makoramu ekuruboshwe nekururudyi emasilinda anofanira kuchinjana kushanda.
3. Kurongeka kwecrank yeinjini ine masilinda akawanda uye kurongeka kwekushanda
Kurongeka kwecrankshaft necrank yeinjini ine mastroke mana iri mumutsara. Nguva yebasa Angle yeinjini ine mastroke mana iri mumutsara i720°/4=180°, macranke mana akarongwa muchikamu chimwe chete, uye nzira yekushanda yeinjini (kana kuti ignition sequence) i1-3-4-2 kana 1-2-4-3. Mudziyo we working cycle thrust unoshandiswa kazhinji une single-sided semi-circular thrust pad ine anti-friction metal layer, crankshaft main bearing ine flanging uye round thrust ring ine mafomu matatu. Thrust pad isimbi ine semi-ring sheet ine anti-friction alloy layer kunze, iyo yakaiswa mu groove yemuviri kana chifukidziro chikuru chebearing. Kuti pasatenderere thrust pad, thrust pad ine bulge yakanamatira mu groove. Mamwe ma thrust pads anoshandisa zvidimbu zvina kugadzira miganhu miviri yakanaka yedenderedzwa, uye mamwe anoshandisa zvidimbu zviviri zvemiganhu. Rutivi rune anti-friction metal runofanira kutarisana ne crankshaft.
Zhuo Meng Shanghai Auto Co., Ltd. yakazvipira kutengesa zvikamu zvemota zveMG&MAUXS zvinogamuchirwa kutenga.
