Iyini i-crankshaft?Yenzani i-crankshaft?Ukwakhiwa kwe-crankshaft?
I-crankshaft ingenye yezingxenye ezibaluleke kakhulu zenjini, ithatha amandla entongeni yokuxhuma futhi iyiguqule ibe yi-torque ephuma ku-crankshaft bese ishayela ezinye izesekeli enjinini ukuze zisebenze.I-crankshaft ithintwa amandla ayi-centrifugal obuningi obujikelezayo, amandla e-periodic inertia yegesi namandla aphindaphindayo e-inertia, okwenza i-crankshaft ithwale isenzo sokugoba kanye nomthwalo we-torsional.Ngakho-ke, i-crankshaft iyadingeka ukuze ibe namandla anele nokuqina, futhi indawo yejenali idinga ukumelana nokugqoka, ifane futhi ilinganisele.I-crankshaft yenziwe ngensimbi ye-carbon structural noma i-ductile iron, futhi ngemva kokufakwa kwenduku yokuxhuma, ingakwazi ukuthwala ukunyakaza okuya phezulu naphansi (okuphindaphindayo) kwenduku yokuxhuma, futhi iyiguqule ibe yindilinga (ejikelezayo).Umsebenzi oyinhloko we-crankshaft ukuguqula ukunyakaza okuhambisanayo okuya phezulu naphansi kwenjini kube ukunyakaza okujikelezayo, ngaleyo ndlela inikeze amandla kulo lonke uhlelo lwemishini.
Indima ye-crankshaft ikakhulukazi ihlanganisa amaphuzu alandelayo:
Amandla okudlulisa: I-crankshaft idlulisela amandla e-piston ku-shaft yokukhipha ngokuguqula ukunyakaza okuhambisanayo kwepiston kube ukunyakaza okuzungezayo, futhi ishayela ezinye izingxenye zenjini ukuthi zisebenze, njengama-valve, ama-piston, izinduku zokuxhuma, njll. .
I-torque yokudlulisa kanye nesivinini: I-crankshaft ingakwazi futhi ukudlulisa i-torque nesivinini senjini ku-shaft okukhiphayo, ukuze imoto ikwazi ukukhiqiza amandla ngenkathi ishayela, ukuze injini ikwazi ukusebenza ngendlela evamile.
I-standard torque: I-crankshaft nayo idinga ukumelana ne-torque namandla angasebenzi enjini ukuze kuqinisekiswe ukusebenza okujwayelekile kwenjini.
I-valve yokulawula: I-crankshaft ilawula ukungena nokukhipha umoya esilinda ngokulawula ukuvulwa nokuvala kwe-valve ukuqinisekisa ukusebenza okuvamile kwenjini.
Ngokuvamile, i-crankshaft ingenye yezingxenye ezibaluleke kakhulu zenjini, indima yayo ukuguqula ukunyakaza okuphindaphindiwe kwe-piston kube ukujikeleza kwesiyingi ku-crankshaft ukushayela ezinye izingxenye zenjini ukuze zisebenze, kodwa futhi kudingeka ukumelana nezinhlobonhlobo zamandla nezikhathi zokuqinisekisa ukusebenza okuvamile kwenjini.
I-crankshaft ikakhulukazi iqukethe izingxenye ezilandelayo:
Intamo yokuphotha: Ingxenye eyinhloko esekelayo ye-crankshaft, esekelwe ibhere elikhulu endaweni yokufaka enkulu ye-crankcase.I-eksisi yentamo yokuphotha yonke isemugqeni ofanayo oqondile.
Ijenali yenduku yokuxhuma (iphinikhodi) : ichezuka eksisi yejenali ye-shaft eyinhloko ukuze kufakwe ijenali yenduku yokuxhuma, futhi kukhona i-engeli ethile phakathi kwejenali yenduku yokuxhuma ukuguqula amandla asuke entongeni yokuxhuma aye ku-torque ejikelezayo ye-crankshaft. .
I-Crank (i-crank arm) : Ingxenye exhumanisa ijenali ye-rod exhumayo kanye nejenali ye-shaft eyinhloko ndawonye ukuze kuguqulwe amandla asuka entweni yokuxhuma aye ku-torque ejikelezayo ye-crankshaft.
I-Counterweight: isetshenziselwa ukulinganisa i-torque eyi-centrifugal engalinganiseli yenjini, futhi ngezinye izikhathi ukulinganisa ingxenye yamandla aphindaphindayo we-inetia ukuze enze i-crankshaft ijikeleze kahle.
I-front-end shaft (isiphelo samahhala): isetshenziselwa ukufaka i-pulley yepompo yamanzi, i-crankshaft timing pulley, njll.
I-Rear end flange: isetshenziselwa ukufaka i-flywheel, ijenali yokuphela kwengemuva kanye ne-flywheel flange phakathi kwe-flange kawoyela nentambo yokubuya, ukuvimbela uwoyela ukuthi ungavuzi emuva.
Umgomo wokusebenza we-crankshaft uhlanganisa ukuguqula amandla asuka entweni yokuxhuma abe yi-torque, ephuma nge-crankshaft futhi iqhube ezinye izesekeli enjinini ukuze zisebenze.Kule nqubo, i-crankshaft ithintwa amandla e-centrifugal wesisindo esijikelezayo, amandla e-inertia yegesi okushintsha ngezikhathi ezithile namandla aphindaphindayo we-inetia, futhi ithwala isenzo sokugoba kanye nomthwalo we-torsional.Ngakho-ke, i-crankshaft idinga ukuba namandla nokuqina okwanele, futhi indawo yejenali idinga ukumelana nokuguga, ifane futhi ilinganisele.
