Injini crankshaft flywheel amacandelo iqela
Okokuqala, crankshaft
I-Crankshaft yenye yezona ndawo zibalulekileyo ze-injini, umsebenzi wayo kukumelana noxinzelelo lwegesi olusuka kwiqela le-piston lokudibanisa intonga kwi-torque ye-crankshaft kunye nemveliso yangaphandle, ukongeza, i-crankshaft isetyenziselwa ukuqhuba indlela ye-valve ye-injini. kunye nezinye izixhobo ezincedisayo (ezifana neejenereyitha, iifeni, iimpompo zamanzi, iimpompo zokuqhuba umbane, i-balance shaft mechanism, njl.njl.)
Iqela le-Crankshaft flywheel: 1- pulley; 2- crankshaft ixesha ivili ibhanti yezinyo; 3- i-crankshaft sprocket; 4- Crankshaft; 5- crankshaft main bearing (phezulu); 6- I-Flywheel; I-7- i-Speed sensor generator signal; I-8, i-11- i-thrust pad; 9- crankshaft main bearing (ezantsi); 10- iCrankshaft isigqumathelo esingundoqo.
Xa i-crankshaft isebenza, kufuneka imelane nokutshintsha kwexesha kuxinzelelo lwegesi, ukuphindaphinda amandla angenayo kunye ne-centrifugal force, kunye ne-torque yabo kunye nomzuzu wokugoba phantsi kwesantya esiphezulu sokusebenza, ukugoba lula kunye nokujija ukuguqulwa, ngoko ke, i-crankshaft kufuneka ibe namandla okwaneleyo. kunye nokuqina, ukuchasana kakuhle kokugqoka kunye nokulinganisela okulungileyo. I-crankshaft ngokubanzi yenziwe ngentsimbi ye-carbon alloy ephakathi, kwaye umphezulu wejenali uphathwa ngokucinywa kwe-high-frequency quenching okanye i-nitriding. I-crankshaft ye-injini ye-Shanghai Santana yenziwe nge-high-quality medium carbon steel die forging. Iinjini ze-Audi JW kunye neYuchai YC6105QC zenziwe ngexabiso eliphantsi, amandla aphezulu anqabileyo anqabileyo emhlabeni kunye nokumelana nokunxiba kakuhle.
1. Ubume becrankshaft
I-crankshaft ngokubanzi yenziwe ngesiphelo sangaphambili, intamo ye-shaft engundoqo, i-crank, i-counterweight, ijenali yokudibanisa intonga kunye nesiphelo esingasemva. I-crank yenziwe yijenali yentonga yokudibanisa kunye neejenali zayo eziziintloko zasekhohlo nasekunene. Inani lekhrenki yecrankshaft lixhomekeke kwinani kunye nolungiselelo lweesilinda. I-crankshaft ye-injini yesilinda enye ine-crank enye kuphela; Inani le-crank ye-crankshaft ye-injini yomgca we-line lilingana nenani leesilinda; Inani leekranki kwi-crankshaft ye-injini engu-V lilingana nesiqingatha senani leesilinda. I-shaft yangaphambili ye-crankshaft ifakwe i-pulley, i-timing gear, njl., esetyenziselwa ukuqhuba impompo yamanzi kunye ne-valve mechanism. Intamo yokusonta ye-crankshaft ifakwe kwisihlalo esiphambili somzimba we-cylinder kwaye isetyenziselwa ukuxhasa i-crankshaft. Ijenali yokudibanisa intonga isetyenziselwa ukufakela intonga yokudibanisa, kwaye i-crank idibanisa ijenali ye-shaft ephambili kunye nejenali yokudibanisa intonga. Ukuze kulinganiswe amandla e-centrifugal xa i-crankshaft ijikeleza, ibhloko yebhalansi inikezelwa kwi-crankshaft. I-flange yokudibanisa ibonelelwe ekupheleni kwe-crankshaft ukudibanisa i-flywheel kwi-crankshaft ngeebholiti. Ukuthambisa ijenali yokudibanisa intonga, isicatshulwa sokuthambisa sigrunjwa ukusuka kwijenali ye-shaft ephambili ukuya kwijenali yentonga yokudibanisa. I-crankshaft edibeneyo ilula kwisakhiwo, ilula kubunzima kwaye inokuthenjwa ekusebenzeni, kwaye ithatha ngokubanzi iibheringi ezicacileyo, ezisetyenziswa ngokubanzi kwiinjini eziphakathi nezincinci.
2. Umgaqo-siseko we-crank
Imilo yecrankshaft kunye nendawo ehambelanayo yecrank nganye ixhomekeke ikakhulu kwinani leesilinda, ulungiselelo lweesilinda kunye nocwangco lomsebenzi wombhobho ngamnye. Xa ucwangcisa ulandelelwano lomsebenzi we-injini, le migaqo ilandelayo kufuneka ilandelwe kangangoko kunokwenzeka:
Yenza iisilinda ezimbini zomsebenzi oqhubekayo ngokude kangangoko kunokwenzeka ukunciphisa umthwalo wokuthwala oyintloko, kwaye ugweme ukwenzeka kweevalve ezimbini ezidibeneyo ezivula ngexesha elifanayo ngexesha lenkqubo yokungena, kwaye i-phenomenon "yokubamba umoya" ichaphazela ukunyuka kwamaxabiso. ukusebenza kakuhle kwe-injini.
(1) I-Angle yekhefu lokusebenza ye-cylinder nganye kufuneka ilingane ukuququzelela ukusebenza kakuhle kwe-injini. Ngaphakathi kwe-engile ye-crankshaft apho injini igqibezela umjikelo wokusebenza, isilinda ngasinye kufuneka sisebenze kube kanye. Kwi-injini ye-four-stroke enenombolo ye-cylinder i, i-interval yomsebenzi i-Angle yi-720 ° / i. Oko kukuthi, yonke i-720 °/i ye-crankshaft kufuneka ibe ne-cylinder yomsebenzi ukuqinisekisa ukuba injini ihamba kakuhle.
(2) Ukuba i-injini yohlobo lwe-V, iikholamu zasekhohlo nasekunene zeesilinda kufuneka zitshintshe umsebenzi.
3. Ulungiselelo oluqhelekileyo lwe-injini ye-multi-cylinder crank kunye nomyalelo wokusebenza
Ulungiselelo lwe-crankshaft kunye ne-crank ye-in-line ye-four-stroke injini. Isithuba somsebenzi I-Angle ye-injini ye-4-cylinder ezine-stroke yi-720 °/4=180 °, i-crank emine icwangciswe kwinqwelomoya enye, kunye nolandelelwano lwe-injini yokusebenza (okanye ukulandelelana kokuvutha) yi-1-3- 4-2 okanye 1-2-4-3. Isixhobo sokutyhala somjikelo wokusebenza esiqhele ukusetyenziswa sinecala elinye elinecala elinye semi-setyhula yokutyhala enomaleko wesinyithi ochasene nefriction, i-crankshaft engundoqo ene-flanging kunye neringi yokutyhala engqukuva ineendlela ezintathu. I-thrust pad yintsimbi ye-semi-ring sheet kunye ne-anti-friction alloy layer ngaphandle, efakwe kwi-groove yomzimba okanye i-cover main cover. Ukuze uthintele ukujikeleza kwe-thrust pad, i-thrust pad ine-bulge ebambelele kwi-groove. Ezinye ii-thrust pads zisebenzisa iziqwenga ezi-4 ukwenza imida emibini yesetyhula evumayo, kwaye ezinye zisebenzisa iziqwenga ezi-2 zemida. Icala eline-anti-friction metal kufuneka lijonge ngase crankshaft.
