Iyini uphawu lwamafutha lwemoto olungemuva lwe-crankshaft?
I-oil seal yangemuva ye-crankshaft, evame ukubizwa ngokuthi "i-oil seal yangemuva ye-crankshaft", iyingxenye ebalulekile yokuvala injini, etholakala endaweni yokuxhumanisa phakathi kwe-crankshaft ne-gearbox.
Umsebenzi wayo oyinhloko ukuvimbela ukuvuza kukawoyela wenjini kusukela ekugcineni kwe-crankshaft kuya ngaphakathi kwebhokisi lamagiya, kuyilapho futhi kuvimbela ukungena kothuli lwangaphandle, ukungcola, kanye nezinye izinto ezingcolisayo enjinini.
Njengesivimbelo, iqinisekisa ukujikeleza okuvamile kohlelo lokugcoba injini, ivimbele ukulahleka kwamafutha okungaholela ekungagculisi injini ngokwanele kanye nomonakalo ongaba khona enjinini. Iphinde ivikele ukusebenza okuvamile kwebhokisi lamagiya.
Ulwazi olubalulekile mayelana nophawu lwamafutha angemuva lwe-crankshaft:
Indawo: Ifakwe ngemuva kwenjini, ohlangothini lapho i-crankshaft idlula khona enjinini futhi ixhumeka ku-input shaft yegiya.
Umsebenzi: Ivimbela uwoyela wenjini ukuthi ungavuzi uye ebhokisini lamagiya futhi igwema ukungcolisa uwoyela webhokisi lamagiya.
Ivimbela uthuli lwangaphandle, umswakama, kanye nokunye ukungcola ukuthi kungangeni ekhabetheni lenjini.
Izici zesakhiwo: Ngokuvamile kuqukethe izinto ezihlanganisiwe zerabha ezihlanganiswe nohlaka lwensimbi. Umlomo ngerabha unamathela eduze ebusweni be-crankshaft ejikelezayo, okwenza uphawu oluguquguqukayo ngokunwebeka; uhlaka lwensimbi luhlinzeka ngokusekelwa kwesakhiwo ukuvimbela ukuguquguquka ngaphansi kwamazinga okushisa aphezulu, ukucindezela okuphezulu, kanye nokujikeleza okusheshayo.
Izinkinga ezivamile: Ngokuhamba kwesikhathi, ngenxa yokushisa okuphezulu, ukuguga, kanye nokuguguleka, uphawu lwamafutha lungase lulahlekelwe ukuqina kwalo, okuholela ekuvuthweni noma ekuvuthweni kwamafutha. Lokhu kuyiphutha elivamile ngemva kokusetshenziswa isikhathi eside, ikakhulukazi kumamodeli aseJalimane naseMelika.
Izici zokulungisa: Ukufaka esikhundleni se-crankshaft oil seal yangemuva kuwumsebenzi wokulungisa odinga umsebenzi omningi. Ngokuvamile kudinga ukuhlukanisa i-gearbox enjinini ngisho nokususa lonke i-gearbox emotweni, ngaleyo ndlela kubangele izindleko eziphezulu zomsebenzi.
Ngamafuphi, yize uphawu lwamafutha lwangemuva lwe-crankshaft luncane, "luyi-invisible guardian" eqinisekisa ukusebenza okuvamile kwenjini kanye ne-gearbox. Uma ivuza, kufanele ishintshwe ngokushesha ukuze kugwenywe umonakalo omkhulu wemishini.
I-oil seal yangemuva ye-crankshaft (ebizwa ngokuthi "i-oil seal yangemuva ye-crankshaft") iyisici esibalulekile sokuvala injini, umsebenzi waso oyinhloko ukuvimbela ukuvuza kwamafutha nokuhlukanisa ukungcola kwangaphandle, ukuqinisekisa ukusebenza okuvamile kwezindawo zokuxhuma injini kanye ne-gearbox.
Imisebenzi ethile yile elandelayo:
Ukuvimbela ukuvuza kwamafutha: I-crankshaft oil seal yangemuva ifakwe ngemuva kwenjini kanye nendawo yokuxhuma ne-gearbox input shaft. Ivala ngempumelelo igebe phakathi kwe-crankshaft ejikelezayo kanye ne-block yesilinda yenjini, ivimbele uwoyela wangaphakathi wenjini ukuthi uvuza ngaphandle, igweme ukulahleka kwamafutha okungaholela ekungagculisi kahle kwenjini kanye nomonakalo ongaba khona wenjini.
Ukuvimbela ukungcola kwangaphandle ukuthi kungangeni: Ngaphezu kokuvala uwoyela wangaphakathi, kuvimbela nothuli, udaka, umswakama, kanye nezinye izinto ezingcolisayo zangaphandle ukuthi zingangeni ekhabetheni lenjini, kugcina ukuhlanzeka kwenjini futhi kwandise isikhathi sokuphila kwengxenye.
Ukugcina ingcindezi yesistimu kanye nokusebenza kahle kokugcoba: Ngokuvala okunamandla okuthembekile (ukuxhumana phakathi komlomo wesivalo samafutha kanye nobuso be-crankshaft ejikelezayo) kanye nokuvala okungaguquki (ukuphazamiseka okuhambisana phakathi komphetho wangaphandle wesivalo samafutha kanye nomgodi wokufaka), kuqinisekisa ukuzinza kwengcindezi yesistimu yokugcoba injini, okuvumela uwoyela wokugcoba ukuthi ujikeleze kahle futhi kuqinisekiswe ukugcotshwa nokupholisa kwezingxenye zenjini.
I-crankshaft oil seal yangemuva ivame ukwakhiwa ngohlaka lwensimbi kanye ne-raber sealing lip, kanye neminye imiklamo enezipilingi eziziqinisayo ukuze kuthuthukiswe ukusebenza kwe-sealing. Ngenxa yokuchayeka isikhathi eside emazingeni okushisa aphezulu kanye nokujikeleza okusheshayo, izoguga futhi iqine noma iguge ngokuhamba kwesikhathi. Uma kukhona ukuvuza, kufanele kushintshwe ngokushesha ukuze kugwenywe ukusetshenziswa kakhulu kwamafutha, ukugcotshwa kwenjini okwanele, kanye nokungcola kwe-clutch noma i-gearbox.
Kuyaphawuleka ukuthi ukufaka esikhundleni se-crankshaft oil seal yangemuva akuyona ingxenye yokulungiswa okukhulu kwemoto kodwa kuyiphrojekthi yokulungisa ezimele engadingi ukuhlakaza izingxenye eziyinhloko zenjini. Kodwa-ke, kudingeka ukusebenza kobungcweti ukuqinisekisa ukunemba kokufakwa.
