Uyini umsebenzi we-crankshaft yemoto
Umsebenzi oyinhloko we-crankshaft yemoto ukuguqula amandla okuphonswa asuka entweni yokuxhuma ipiston abe amandla ajikelezayo e-torque, ukuze ashayele isistimu yokuhambisa imoto kanye ne-valve yenjini namanye amadivaysi asizayo. I-Crankshaft ingenye yezingxenye ezijwayelekile nezibalulekile enjinini, umsebenzi wayo ukuguqula umfutho wegesi odluliswa yinduku yokuxhuma i-piston ibe yi-torque, futhi yenze umsebenzi wokuphuma kwamandla ukushayela ezinye izindlela zokusebenza. .
Isebenza kanjani i-crankshaft
I-crankshaft ibona ukuguqulwa nokudluliswa kwamandla ngokuguqula ukunyakaza okuhambisanayo komugqa kwepiston kube ukunyakaza okuzungezayo. Ingaphansi kwemithwalo eshintshanayo eyinkimbinkimbi, okuhlanganisa indima yezinguquko zezikhathi ezithile kumandla we-aerodynamic, amandla angasebenzi kanye nomzuzwana, ngakho-ke i-crankshaft iyadingeka ukuze ibe namandla anele okukhathala nokuqina ngokumelene nokugoba nokuzulazula.
Isakhiwo kanye nempahla ye-crankshaft
Ama-crankshafts ngokuvamile enziwa ngensimbi ye-alloy high-strength enamandla amakhulu aqinile kanye nokuqina okuhle. Isakhiwo sayo sihlanganisa intamo ye-shaft eyinhloko, intamo yenduku yokuxhuma nezinye izingxenye, eziklanyelwe kanye nezinto ezikhethiwe ukuze kuqinisekiswe ukuthi i-crankshaft ingakwazi ukumelana namandla amakhulu kanye ne-torque ngesivinini esiphezulu, kuyilapho igcina ukujikeleza okuzinzile.
Ukugcinwa kwe-Crankshaft kanye nezinkinga ezivamile
I-crankshaft ingase igobe futhi isonteke phakathi nokusetshenziswa ngezizathu ezihlukahlukene, okuzophazamisa umsebenzi wayo ovamile. Ukuze kuqinisekiswe ukusebenza okuvamile kwe-crankshaft, ukuhlolwa nokugcinwa njalo kuyadingeka, kuhlanganise nokuhlola ukuguga, ibhalansi kanye nokucaciswa kwe-crankshaft. Izinkinga zokulungisa ezijwayelekile zifaka ukugoba kwe-crankshaft kanye ne-torsion, okungaholela ekunciphiseni ukusebenza kwenjini noma ukwehluleka.
I-automobile crankshaft ephukile ingathatha izindlela ezilandelayo zokulungisa nokufaka esikhundleni sayo:
Indlela yokulungisa:
Ukugaya : Ngokuguga okuncane, ungqimba lwensimbi lungasuswa endaweni ye-crankshaft ngokugaya ukuze kubuyiselwe usayizi nokuma kwayo. Lokhu kudinga okokusebenza okunemba okuphezulu nochwepheshe abangochwepheshe ukuze kusebenze.
ukushisela : Uma kukhona ukuqhekeka ku-crankshaft, kungalungiswa ngokushisela. Kodwa-ke, inqubo yokushisela idinga ukulawulwa okuqinile kokushisa kanye nenqubo yokuvimbela ukuguquguquka nokucindezeleka okusele. Ukwelashwa kokushisa nokutholwa kwamaphutha nakho kuyadingeka ngemva kokushisela.
ukulinganisa : Kuma-crankshaft agobile, umshini wokucindezela ungasetshenziswa ukuwalungisa. Inqubo yokulungisa idinga ukulinganisa okunembile kwezinga kanye nesimo sokugoba, kanye nokusetshenziswa kancane kancane kokucindezela kuze kube yilapho isimo esiqondile sibuyiselwa. Ngemva kokulungiswa, ukutholwa kwamaphutha nokutholwa kwebhalansi eguqukayo kuyadingeka .
Ukushintsha indlela:
Khetha i-crankshaft elungile : Khetha i-crankshaft efanele ukuze uyishintshe ngokuya ngemodeli nohlobo lwenjini yemoto. Qinisekisa ukuthi okokusebenza, usayizi nokusebenza kwe-crankshaft entsha kufana nokwasekuqaleni.
ukufakwa kochwepheshe : Ukushintsha i-crankshaft kudinga ubuchwepheshe obuchwepheshile kanye nemishini. Phakathi nenqubo yokufaka, naka ibhalansi ye-crankshaft, imvume efanayo kanye namandla okuqinisa amabhawodi angashintshi.
ukuhlolwa nokuqinisekisa : Ngemva kokushintshwa, ukuhlolwa okuphelele kuzokwenziwa, okuhlanganisa ukutholwa kokukhubazeka kanye nebhalansi eguqukayo, ukuze kuqinisekiswe ukuthi i-crankshaft ingasebenza ngendlela evamile futhi ayithinti ukusebenza kwenjini.
Izinyathelo zokuvimbela:
Ukugcinwa okuvamile : buyisela isihlungi sikawoyela namafutha ngesikhathi ukuze uqinisekise umsebenzi ojwayelekile wesistimu yokugcoba futhi ugweme ukungqubuzana okomile nokuguga.
ukuhlola nokunakekela : hlola isimo se-crankshaft njalo, okuhlanganisa igebe elihambisanayo phakathi kwejenali negobolondo elithwele, ukugoba nokuhlanekezelwa kwe-crankshaft.
gwema ukugcwala ngokweqile : gwema ukusebenza kwenjini isikhathi eside, nciphisa umonakalo odalwe ukushisa ngokweqile kanye nengcindezi yemishini.
