Uyini umsebenzi we-crankshaft yemoto
Umsebenzi oyinhloko we-crankshaft yemoto ukuguqula amandla okusunduza kusuka endukwini yokuxhuma ye-piston abe amandla e-torque ajikelezayo, ukuze kushayelwe uhlelo lokudlulisa imoto kanye nendlela ye-valve yenjini kanye namanye amadivayisi asizayo. I-crankshaft ingenye yezingxenye ezijwayelekile nezibaluleke kakhulu enjinini, umsebenzi wayo ukuguqula ingcindezi yegesi edluliselwa yinduku yokuxhuma ye-piston ibe yi-torque, futhi isebenze njengokukhipha amandla ukushayela ezinye izindlela zokusebenza.
Indlela i-crankshaft esebenza ngayo
I-crankshaft ikwazi ukuguqula nokudlulisa amandla ngokuguqula ukunyakaza okuqondile okuhambisanayo kwe-piston kube ukunyakaza okujikelezayo okujikelezayo. Ibhekana nemithwalo eguquguqukayo eyinkimbinkimbi, okuhlanganisa nendima yezinguquko eziqhubekayo emandleni e-aerodynamic, amandla angenawo amandla kanye nomzuzu, ngakho-ke i-crankshaft iyadingeka ukuze ibe namandla okukhathala anele kanye nokuqina ngokumelene nokugoba kanye nokugoba.
Isakhiwo kanye nezinto ze-crankshaft
Ama-crankshaft ngokuvamile enziwa ngensimbi ye-alloy enamandla amakhulu enamandla okudonseka aphezulu kanye nokuqina okuhle. Isakhiwo sawo sihlanganisa intamo yomgodi oyinhloko, intamo yenduku yokuxhuma kanye nezinye izingxenye, eziklanyelwe kanye nezinto ezikhethiwe ukuqinisekisa ukuthi i-crankshaft ingakwazi ukumelana namandla amakhulu kanye ne-torque ngesivinini esikhulu, ngenkathi igcina ukujikeleza okuzinzile.
Ukugcinwa kwe-crankshaft nezinkinga ezivamile
I-crankshaft ingagoba futhi ijike ngesikhathi sokusetshenziswa ngezizathu ezahlukahlukene, okuzothinta ukusebenza kwayo okuvamile. Ukuze kuqinisekiswe ukusebenza okuvamile kwe-crankshaft, kudingeka ukuhlolwa nokugcinwa njalo, okuhlanganisa nokuhlola ukuguguleka, ibhalansi kanye nokuvuleka kwe-crankshaft. Izinkinga ezivamile zokulungisa zifaka phakathi ukugoba kwe-crankshaft kanye nokugoba, okungaholela ekunciphiseni ukusebenza kwenjini noma ukwehluleka.
I-crankshaft yemoto ephukile ingathatha izindlela ezilandelayo zokulungisa nokufaka esikhundleni:
Indlela yokulungisa:
Ukugaya : Uma kugqokwa kancane, ungqimba lwensimbi lungasuswa ebusweni be-crankshaft ngokugaya ukuze kubuyiselwe usayizi nesimo salo. Lokhu kudinga imishini enembile kakhulu kanye nochwepheshe abangochwepheshe ukuze basebenze .
Ukushisela: Uma kukhona ukuqhekeka ku-crankshaft, kungalungiswa ngokushisela. Kodwa-ke, inqubo yokushisela idinga ukulawulwa okuqinile kwezinga lokushisa kanye nenqubo ukuvimbela ukuguquka kanye nokucindezeleka okusele. Ukwelashwa kokushisa kanye nokutholwa kwamaphutha nakho kuyadingeka ngemva kokushisela.
Ukulinganiswa : Kuma-crankshaft agobile, ukucindezela kungasetshenziswa ukuwalungisa. Inqubo yokulungisa idinga ukulinganiswa okunembile kwezinga nendawo yokugoba, kanye nokusetshenziswa kancane kancane kwengcindezi kuze kube yilapho isimo esiqondile sibuyiselwa. Ngemva kokulungiswa, ukutholwa kwamaphutha kanye nokutholwa kwebhalansi eguquguqukayo kuyadingeka .
Indlela Yokushintsha:
Khetha i-crankshaft efanele: Khetha i-crankshaft efanele yokushintshwa ngokwemodeli kanye nohlobo lwenjini yemoto. Qinisekisa ukuthi izinto zokwakha, usayizi kanye nokusebenza kwe-crankshaft entsha kufana neyasekuqaleni.
ukufakwa kobungcweti : Ukufaka esikhundleni se-crankshaft kudinga ubuchwepheshe kanye nemishini yobungcweti. Ngesikhathi senqubo yokufaka, naka ibhalansi ye-crankshaft, ukuhlukaniswa okulinganayo kanye namandla okuqinisa amabhawodi aqinile .
Ukuhlolwa nokuqinisekiswa: Ngemva kokufakwa esikhundleni, kuzokwenziwa ukuhlolwa okuphelele, okuhlanganisa ukutholwa kwamaphutha kanye nebhalansi eguquguqukayo, ukuqinisekisa ukuthi i-crankshaft ingasebenza kahle futhi ayithinti ukusebenza kwenjini.
Izinyathelo zokuvimbela:
Ukulungiswa okuvamile : shintsha isihlungi samafutha namafutha ngesikhathi ukuqinisekisa ukusebenza okuvamile kohlelo lokugcoba futhi ugweme ukungqubuzana okomile nokuguguleka .
ukuhlola nokulungisa: hlola isimo se-crankshaft njalo, kufaka phakathi igebe elihambisanayo phakathi kwejenali negobolondo lokuthwala, ukugoba nokuphambuka kwe-crankshaft.
gwema ukulayisha ngokweqile: gwema ukusebenza kwenjini isikhathi eside, nciphisa umonakalo obangelwa ukushisa ngokweqile kanye nokucindezeleka komshini.
