Ukuphuka kwe-crankshaft ngokuvamile kuqala kusukela ekuqhekekeni okuncane kakhulu, futhi iningi lemifantu livela engxenyeni exhumayo yengalo ye-crank ku-fillet yejenali yenduku yokuxhuma yesilinda sekhanda noma isilinda sokugcina. Ngesikhathi sokusebenza, ukuqhekeka kuyakhula kancane kancane futhi kuphule ngokuzumayo lapho kufinyelele ezingeni elithile. Ingxenye ensundu ivame ukutholakala endaweni ephukile, okusobala ukuthi kuwumfantu omdala, futhi izicubu ezicwebezelayo nezicwebezelayo ziwumkhondo owathuthukela ekuqhekekeni kungazelelwe kamuva. Namuhla, ake sibheke ukuthi yini ebangela ukuphuka kwe-crankshaft!
1. Amakhona ayindilinga kuzo zombili iziphetho zejenali ye-crankshaft mancane kakhulu
Lapho igaya i-crankshaft, umshini wokugaya uhlulekile ukulawula kahle i-fillet yejenali ye-crankshaft. Ngaphezu kokucutshungulwa kwe-camber, i-fillet radius yayincane kakhulu, ngakho-ke ukugxiliswa kwengcindezi okukhulu kwakhiqizwa ku-fillet lapho i-crankshaft isebenza, futhi i-crankshaft yafushaniswa. impilo yokukhathala.
2. I-offset ye-crankshaft main journal axis
I-axis yejenali eyinhloko ye-crankshaft i-offset, ecekela phansi ibhalansi eguquguqukayo yomhlangano we-crankshaft. Lapho injini igijima ngesivinini esikhulu, kukhiqizwa amandla anamandla angasebenzi, abangela ukuphuka kwe-crankshaft.
3. Umncintiswano obandayo we-crankshaft mkhulu kakhulu
I-crankshaft izogoba kakhulu ngemva kokusetshenziswa isikhathi eside, ikakhulukazi ngemva kwengozi yokushiswa kwamathayili noma ukugxoba isilinda, futhi kufanele isuswe futhi ilungiswe ngokucindezela okubandayo. Ngenxa yokuguqulwa kwepulasitiki yensimbi ngaphakathi kwe-crankshaft ngesikhathi sokulinganisa, kuzokwenziwa ingcindezi enkulu eyengeziwe, ngaleyo ndlela kuncishiswe amandla e-crankshaft. Uma ukuncintisana okubandayo kukhulu kakhulu, i-crankshaft ingase yonakaliswe noma iqhekeke, futhi le crankshaft izophuka ngokushesha ngemva kokufakwa.
4. I-flywheel ixega
Uma ibhawodi le-flywheel lixega, i-crankshaft izolahlekelwa ibhalansi yayo yasekuqaleni, futhi injini izodlidliza ngemva kokugijima, futhi ngesikhathi esifanayo, amandla amakhulu angena ngaphakathi azokhiqizwa, okuholela ekukhathaleni kwe-crankshaft kanye nokuphuka kalula ku-crankshaft. ngemuva.
5. Ikhwalithi embi ye-crankshaft ngokwayo
Ukuthenga ama-crankshaft akufanele kube ukuhaha ngemali eshibhile, futhi kufanele kuthengwe eziteshini ezivamile. Kufanele futhi ihlolwe ngokucophelela ngaphambi kokufakwa, futhi uma kukhona inkinga, kufanele ishintshwe noma ibuyiselwe ngesikhathi. Ngaphezu kwalokho, uma injini ilungiswa kabusha, i-crankshaft kufanele itholwe ukuthi kukhona ukungasebenzi kahle kazibuthe noma ukuhlolwa kokucwiliswa kukawoyela. Uma kukhona ukuqhekeka kwe-radial noma kwe-axial okudlulela ku-fillet yehlombe ebusweni bejenali, i-crankshaft ayikwazi ukuphinda isetshenziswe.
6. Isihlahla esikhulu sihlukile ku-shaft
Lapho i-crankshaft ihlanganiswa, uma imigqa emaphakathi yezihlahla ezinkulu ezithwalayo ku-cylinder block ingekho e-eksisi efanayo, ingozi yokushiswa kwezihlahla ezithwalayo nokubamba i-shaft izokwenzeka kalula ngemva kokuba injini isebenza, futhi i-crankshaft nayo izophuka. ngaphansi kwesenzo esinamandla sokushintshana kokucindezeleka.
