1. Ukwehluleka ukuncibilika kweCrankshaft

Lapho i-crankshaft ethwele inyibilika, ukusebenza kwenjini ngemva kokwenzeka kwephutha ukuthi: umsindo wokungqongqoza wensimbi oshubile futhi onamandla uzokhishwa kubheringi eyinhloko encibilikisiwe. Uma wonke ama-bearings encibilika noma exega, kuzoba khona umsindo ocacile othi "dang, pang". Imbangela yokwehluleka

(1) Ukucindezela kwamafutha okugcoba ayanele, amafutha okugcoba awakwazi ukukhama phakathi kweshaft kanye ne-bearing, ukuze i-shaft ne-bearing ibe sesimweni sokungqubuzana esomile noma esomile, okubangela ukuthi izinga lokushisa likhuphuke. futhi i-anti-friction alloy iyancibilika.

(2) Iphaseji likawoyela wokugcoba, umqoqi kawoyela, isihluzi sikawoyela, njll. kuvinjwe ukungcola, futhi ivalve yokudlula esisefweni ayikwazi ukuvulwa (ukulayisha kuqala kwesiphethu sevalvu kukhulu kakhulu noma ivalve yesiphethu nebhola ivaleleke eduze. ukungcola, njll.), Kubangele ukuphazamiseka kokunikezwa kukawoyela wokugcoba.

(3) Igebe phakathi kwe-shaft ne-bearing lincane kakhulu ukwenza ifilimu kawoyela; ukuthwala kufushane kakhulu futhi akunasiphazamiso nembobo yezindlu ezithwele, okubangela ukuthwala ukujikeleza emgodini wezindlu, ukuvimbela imbobo yokudlula uwoyela emgodini wezindlu ezithwalayo, nokuphazamisa ukunikezwa kwamafutha okugcoba .

(4) Ukujikeleza kwejenali ye-crankshaft kubi kakhulu. Phakathi nenqubo yokugcoba, kunzima ukwenza ifilimu ethile kawoyela ngoba iphephabhuku aliyindilinga (imvume yokuthwala ngezinye izikhathi inkulu futhi ngezinye izikhathi incane, futhi ifilimu kawoyela ngezinye izikhathi iwugqinsi futhi ngezinye izikhathi incane), okuholela ekugcobeni kabi.

(5) Ukuguqulwa komzimba noma iphutha lokucubungula, noma ukugoba i-crankshaft, njll., kwenza imigqa emaphakathi yebheringi ngayinye eyinhloko ingaqondani, okubangela ukushuba kwefilimu kawoyela yebhile ngayinye ukuthi ingalingani lapho u-crankshaft uzungeza, futhi kuze kube ukungqubuzana okomile. isimo sokuncibilikisa i-bearing.

(6) Inani lamafutha okugcoba epanini likawoyela alanele futhi izinga lokushisa likawoyela liphezulu kakhulu, noma uwoyela wokugcoba uhlanjululwa ngamanzi noma ngophethiloli, noma kusetshenziswe uwoyela wokugcoba wekhwalithi ephansi noma uphawu olungaguquki.

(7) Ukulingana okungalungile phakathi kwengemuva lebhere kanye nembobo yesihlalo esinesihlalo noma i-copper padding, njll., okuholela ekushiseni okungekuhle.

(8) Ukushesha kakhulu kwenjini ngokushesha, njengokuthi "ijubane" lenjini kadizili, nakho kungesinye sezizathu zokushiswa kwamabheringi.

Ukuvimbela amaphutha kanye nezindlela zokuxazulula izinkinga

(1) Ngaphambi kokufaka umhlangano wenjini, qaphela ukuhlanzwa nokuhlolwa kwephaseji likawoyela wokugcoba (geza ngamanzi anomfutho ophezulu noma umoya), susa udoti ovimba isihlungi, futhi uqinise ukugcinwa kwesisefo esimahhadla ukuze uvimbele. isici sokuhlunga ekuvalelekeni kanye nevalve yokudlula ingasebenzi.

(2) Umshayeli kufanele abheke izinga lokushisa kwenjini nomfutho kawoyela wokugcoba nganoma yisiphi isikhathi, futhi ahlole umsindo ongajwayelekile enjinini; hlola inani kanye nekhwalithi yamafutha okugcoba ngaphambi kokushiya imoto.

(3) Thuthukisa ikhwalithi yokugcinwa kwenjini futhi uqinise ukuhlolwa kokulungisa kwangaphambili kwezingxenye eziyisisekelo.

(4) Ukuklwebha kwebheringi eyinhloko ye-crankshaft kufanele kwenze indawo ephakathi nendawo ngayinye yembobo yendlu ebambekayo igxile. Endabeni yokuphambuka okuncane nokulungiswa ngokulangazela, indlela yokukhuhla yokuqala ukulungisa umugqa ovundlile ingasetshenziswa. Umsebenzi wokukhuhla uhlobene nokuthwala induku yokuxhuma. Kucishe kufane.

2. I-crankshaft main bearing yenza umsindo

Ukusebenza kwenjini ngemva komsindo ovela ekuthwaleni i-crankshaft kubangelwa umthelela wejenali eyinhloko ye-crankshaft kanye nokuthwala. Lapho i-accelerator pedal incibilika noma iwa, injini izovevezela kakhulu lapho i-accelerator pedal icindezeleke kakhulu. I-bearing eyinhloko igugile, futhi imvume ye-radial inkulu kakhulu, futhi kuzoba nomsindo onzima futhi ongacacile wokungqongqoza. Uma ijubane lenjini liphakeme, umsindo uyanda, nomsindo ukhula ngokukhula komthwalo. Imbangela yokwehluleka

(1) Ama-bearings namajenali agqokwa kakhulu; amabhawodi okubopha wekhava elithwalayo awakhiyiwe ngokuqinile futhi akhululiwe, okwenza imvume ehambisanayo phakathi kwe-crankshaft ne-bearing ibe mkhulu kakhulu, futhi lezi ezimbili zenza umsindo lapho zishayisana.

(2) Ingxubevange ethwalayo iyancibilika noma iwe; ukuthwala kude kakhulu futhi ukuphazamiseka kukhulu kakhulu, okubangela ukuphuka, noma ukuthwala kufushane kakhulu ukuthi kungabekwa kahle futhi kukhululeke emgodini wezindlu ezithwele, okubangela ukuthi kokubili kungqubuzane.

Ukuvimbela amaphutha kanye nezindlela zokuxazulula izinkinga

(1) Ukwenza ngcono izinga lokugcinwa kwenjini. Amabhawodi okulungisa ikhava yokuthwala kufanele aqiniswe futhi akhiywe. Ukuthwala akufanele kube kude kakhulu noma kufushane kakhulu ukuze kuqinisekiswe inani elithile lokuphazanyiswa.

(2) Izinga lokuthambisa elisetshenziswayo kufanele libe elilungile, akufanele kusetshenziswe isithambisi esisezingeni eliphansi, futhi izinga lokushisa elifanele lokugcoba nokucindezela kufanele kugcinwe.

(3) Gcina isimo esihle sokusebenza sesistimu yokuthambisa, buyisela amafutha okugcoba ngesikhathi esifanele, futhi ugcine isihlungi sikawoyela wokuthambisa njalo.

(4) Lapho ushayela, umshayeli kufanele anake ukushintsha komfutho kawoyela, futhi ahlole ngokushesha ukuthi kutholakala ukusabela okungavamile yini. Lapho igebe lokuzala lizwakala kakhulu, igebe lokuzala kufanele lilungiswe. Uma ingakwazi ukulungiswa, ukuthwala kungashintshwa futhi kukhishwe. Uma isilinda sejenali ye-crankshaft yeqa umkhawulo wesevisi, ijenali ye-crankshaft kufanele ipholishwe futhi ukuthela kufanele kuphinde kukhethwe.
