Yintoni itywina yeoyile ye-crankshaft yangasemva yemoto?
Itywina yeoyile ye-crankshaft yangasemva, edla ngokubizwa ngokuba yi-"crankshaft rear oil seal", yinxalenye ebalulekileyo yokutywina kwinjini, ekwindawo yokudibanisa phakathi kwe-crankshaft kunye ne-gearbox.
Umsebenzi wayo ophambili kukuthintela ukuvuza kweoyile yenjini ukusuka ngasemva kwe-crankshaft ukuya ngaphakathi kwebhokisi yegiya, ngelixa ikwathintela ukungena kothuli lwangaphandle, ukungcola, kunye nezinye izinto ezingcolisayo kwinjini.
Njenge "mqobo", iqinisekisa ukujikeleza okuqhelekileyo kwenkqubo yokuthambisa injini, ithintela ukulahleka kweoyile okunokubangela ukuthambisa okwaneleyo kwenjini kunye nomonakalo onokubakho kwinjini. Ikwakhusela ukusebenza okuqhelekileyo kwebhokisi yegiya.
Ulwazi oluphambili malunga netywina yeoyile yangasemva ye-crankshaft:
Indawo: Ifakwe ngasemva kwenjini, kwicala apho i-crankshaft iphuma khona kwinjini kwaye iqhagamshele kwi-gearbox input shaft.
Umsebenzi: Ithintela ioyile yenjini ekuvuzeni kwibhokisi yegiya kwaye ithintela ukungcolisa ioyile yebhokisi yegiya.
Ithintela uthuli lwangaphandle, ukufuma, kunye nokunye ukungcola ukuba kungangeni kwi-crankcase yenjini.
Iimpawu zesakhiwo: Ngokwesiqhelo iqulathe izinto zerabha ezidityanisiweyo ezidityaniswe nesakhelo sesinyithi. Umlebe werabha unamathela ngokusondeleyo kumphezulu we-crankshaft ejikelezayo, okwenza isitywina esiguquguqukayo ngokuthamba; isakhelo sesinyithi sibonelela ngenkxaso yesakhiwo ukuthintela ukuguquka phantsi kobushushu obuphezulu, uxinzelelo oluphezulu, kunye nokujikeleza ngesantya esiphezulu.
Iingxaki eziqhelekileyo: Ekuhambeni kwexesha, ngenxa yobushushu obuphezulu, ukuguga, kunye nokuguguleka, isitywini seoyile sinokuphelelwa bubuthambile baso, nto leyo ebangela ukuvuza okanye ukuvuza kweoyile. Le yingxaki eqhelekileyo emva kokusetyenziswa ixesha elide, ingakumbi kwiimodeli zaseJamani naseMelika.
Iimpawu zolondolozo: Ukutshintsha isitywina seoyile sangasemva se-crankshaft ngumsebenzi wokulungisa onzima kakhulu. Ngokuqhelekileyo kufuna ukwahlukanisa i-gearbox kwinjini kwanokususa yonke i-gearbox kwisithuthi, nto leyo ebangela iindleko eziphezulu zomsebenzi.
Ngamafutshane, nangona isitywini seoyile sangasemva se-crankshaft sincinci, "sisithinteli esingabonakaliyo" esiqinisekisa ukusebenza okuqhelekileyo kwenjini kunye nebhokisi yegiya. Ukuba iyavuza, kufuneka itshintshwe ngokukhawuleza ukuze kuthintelwe umonakalo omkhulu woomatshini.
I-oil seal yangasemva ye-crankshaft (ebizwa ngokuba yi-"crankshaft rear oil seal") yinxalenye ebalulekileyo yokuvala injini, umsebenzi wayo ophambili kukuthintela ukuvuza kweoyile kunye nokwahlula izinto ezingcolisayo zangaphandle, ukuqinisekisa ukusebenza okuqhelekileyo kweendawo zokudibanisa injini kunye nebhokisi yegiya.
Imisebenzi ethile yile ilandelayo:
Ukuthintela ukuvuza kweoyile: I-crankshaft oil seal engasemva ifakwe ngasemva kwenjini nakwindawo yokudibanisa ne-gearbox input shaft. Ivala ngokufanelekileyo umsantsa phakathi kwe-crankshaft ejikelezayo kunye ne-engine cylinder block, ithintela ioyile yangaphakathi yenjini ekuvuzeni ngaphandle, ithintela ukulahleka kweoyile okunokubangela ukungoneli kwe-engine lubrication kunye nomonakalo onokwenzeka kwinjini.
Ukuthintela ukungcola kwangaphandle ukuba kungangeni: Ukongeza ekuvaleni ioyile yangaphakathi, ikwathintela uthuli, udaka, ukufuma, kunye nezinye izinto ezingcolisayo zangaphandle ukuba zingangeni kwi-crankcase yenjini, igcina ucoceko lwenjini kwaye yandisa ubomi benxalenye.
Ukugcina uxinzelelo lwenkqubo kunye nokusebenza kakuhle kokuthambisa: Ngokusebenzisa ukutywina okunamandla okuthembekileyo (ukudibana phakathi komlomo wesitywini seoyile kunye nomphezulu we-crankshaft ojikelezayo) kunye nokutywina okungaguqukiyo (ukuphazamiseka kuhambelana phakathi komphetho wangaphandle wesitywini seoyile kunye nomngxuma wokufakelwa), kuqinisekisa uzinzo loxinzelelo lwenkqubo yokuthambisa injini, okuvumela ioyile yokuthambisa ukuba ijikeleze ngokufanelekileyo kwaye iqinisekisa ukuthambisa kunye nokuphola kwamacandelo enjini.
I-crankshaft oil seal engasemva idla ngokwenziwa yi-framework yesinyithi kunye ne-raber sealing lip, kunye nezinye iindlela zoyilo ezinezipringi eziziqinisayo ukuphucula ukusebenza kwe-sealing. Ngenxa yokuvezwa ixesha elide kumaqondo obushushu aphezulu kunye nokujikeleza ngesantya esiphezulu, iya kuguga kwaye iqine okanye iguge ngokuhamba kwexesha. Ukuba kukho ukuvuza, kufuneka itshintshwe ngokukhawuleza ukuze kuthintelwe ukusetyenziswa kakhulu kweoyile, ukuthambisa okwaneleyo kwenjini, kunye nongcoliseko lwe-clutch okanye i-gearbox.
Kubalulekile ukuqaphela ukuba ukutshintsha isitywina seoyile sangasemva se-crankshaft akuyonxalenye yokulungiswa okukhulu kwesithuthi kodwa yiprojekthi yolondolozo ezimeleyo engadingi kudibanisa iindawo eziphambili zenjini. Nangona kunjalo, kufuneka ukusebenza kobuchwephesha ukuqinisekisa ukuchaneka kokufakwa.
