Ukuphuka kwe-crankshaft ngokuvamile kuqala kusukela ekuqhekekeni okuncane kakhulu, futhi iningi lemifantu nokuphuka kwenzeka engxenyeni yokuxhuma yengalo ye-crank emakhoneni ayindilinga ejenali yenduku yokuxhuma yesilinda sekhanda noma isilinda sokugcina. Ngesikhathi sokusebenza, ukuqhekeka kwanda kancane kancane futhi kwaphuka ngokuzumayo lapho kufinyelele ezingeni elithile. Ingxenye ensundu ivame ukutholakala endaweni ephukile, okusobala ukuthi umfantu omdala, futhi isakhiwo esicwebezelayo nesicwebezelayo siwuphawu lokuphuka kungazelelwe kamuva. Ake sibheke imbangela ye-crankshaft ephukile nawo wonke umuntu namuhla! Inkinga yokuphuka kwe-crankshaft yenjini

1. Amakhona ayindilinga kuzo zombili iziphetho zejenali ye-crankshaft mancane kakhulu

Lapho igaya i-crankshaft, i-grinder yehlulekile ukulawula kahle i-axial fillet ye-crankshaft. Ngaphezu komshini omangelengele, i-fillet radius nayo incane kakhulu. Ngakho-ke, lapho i-crankshaft isebenza, ukugxila okukhulu kokucindezeleka kwenzeka ku-fillet, futhi i-crankshaft iyafinyezwa. Impilo yokukhathala.

2. I-offset ye-crankshaft main journal axis

I-axis yejenali eyinhloko ye-crankshaft iyachezuka, okulimaza ibhalansi eguquguqukayo yomhlangano we-crankshaft. Lapho injini kadizili igijima ngesivinini esikhulu, ikhiqiza amandla anamandla angasebenzi, abangela ukuphuka kwe-crankshaft.

3. Umncintiswano obandayo we-crankshaft mkhulu kakhulu

Ngemva kokusetshenziswa kwesikhathi eside kwe-crankshaft, ikakhulukazi ngemva kokuvela kwezingozi zokushiswa kwamathayili noma i-cylinder ramming, ukugoba okukhulu kuzokwenzeka, futhi kufanele kususwe ukuze kulungiswe ukucindezela okubandayo. Ngenxa yokuguqulwa kwepulasitiki kwensimbi yangaphakathi ye-crankshaft ngesikhathi sokulinganisa, kuzokwenziwa ukucindezeleka okukhulu okwengeziwe, ngaleyo ndlela kuncishiswe amandla e-crankshaft. Uma ukuncintisana okubandayo kukhulu kakhulu, i-crankshaft ingase yonakaliswe noma iqhekeke. Lolu hlobo lwe-crankshaft luzophuka ngemuva nje kokusetshenziswa.

4. I-flywheel ixega

Uma amabhawodi e-flywheel exega, umhlangano we-crankshaft uzolahlekelwa ibhalansi yawo yokuqala eguquguqukayo, futhi injini kadizili izozamazama ngemva kokugijima, futhi ngesikhathi esifanayo kuzokhiqizwa amandla amakhulu angasebenzi, okuzokwenza ukuthi i-crankshaft ikhathale futhi iphuke kalula. ukuphela komsila.

5. Izinga le-crankshaft ngokwayo liphansi

Ungathengi ama-crankshafts ngemali eshibhile, kufanele uwathenge eziteshini ezijwayelekile. Kufanele ihlolwe ngokucophelela ngaphambi kokufakwa, futhi uma kukhona inkinga, kufanele ishintshwe noma ibuyiselwe ngesikhathi. Ukwengeza, lapho injini ilungiswa kabusha, i-crankshaft kufanele ihlolwe ngokuhlola kazibuthe noma ngokuthinta uwoyela ngokucwiliswa. Uma indawo yejenali inemifantu eyi-radial noma imifantu ye-axial efinyelela emakhoneni ayindilinga ehlombe, i-crankshaft ngeke isakwazi ukusetshenziswa.

6. I-eksisi ehlukene yokuthela okuyinhloko

Lapho uhlanganisa i-crankshaft, uma imigqa emaphakathi yezihlahla ezinkulu ku-cylinder block ihlukile ku-axis, injini ye-diesel izoba sengozini yokushiswa kwehlathi kanye nezingozi zokubamba i-axle ngemva kokuhlinzwa, futhi i-crankshaft izophuka ngaphansi kwesenzo esinamandla. ukushintshana kokucindezeleka.

7. Imvume yokuhlanganisa i-crankshaft inkulu kakhulu

Uma imvume ehambisanayo phakathi kwejenali ye-crankshaft kanye nesihlahla esithwalayo inkulu kakhulu, i-crankshaft izoba nomthelela esihlahleni esithwalayo ngemva kokuba injini kadizili isiphelile, kodwa ingxubevange izowa bese isihlahla sishise futhi sibambe i-shaft, futhi i-crankshaft izoba. futhi zilimale kalula.

8. Isikhathi sokunikezwa kwamafutha sisheshe kakhulu noma umthamo kawoyela wesilinda ngasinye awulingani

Uma isikhathi sokuphakelwa kukaphethiloli kwepompo lomjovo kaphethiloli singaphambi kwesikhathi kakhulu, i-piston izosha futhi isebenze ngaphambi kwesikhungo esiphezulu esifile, okuzobangela ukuba injini yedizili igingqike futhi i-crankshaft iphazamiseke ngokushintshana kokucindezeleka. Uma ukunikezwa kukawoyela kwe-cylinder ngayinye kungalingani, amandla ejenali ngayinye ye-crankshaft azolingana ngenxa yokungahambisani kwecala lokuqhuma kwe-cylinder ngayinye, okuzodala ukukhathala ngaphambi kwesikhathi nokuqhekeka.

9. Ukugcotshwa kwe-crankshaft okungekuhle

Uma iphampu yamafutha igugile kakhulu, isiteshi sikawoyela wokugcoba singcolile, futhi ukugeleza akusheleli, ukunikezwa kwamafutha ngeke kwanele futhi ukucindezela kwamafutha kuzokwehla, okuholela ekuhlulekeni kwefilimu evamile yamafutha okugcoba phakathi kwe-crankshaft ne-crankshaft. izihlahla ezithwalayo, okuzodala ukungqubuzana okomile futhi kubangele ukushiswa kwezihlahla nama-shafts. , Ukugqekeza i-crankshaft nezinye izingozi ezinkulu.

10. Ukuphuka kwe-crankshaft okubangelwa ukuhlinzwa okungafanele

Uma i-throttle iphezulu kakhulu noma iphansi kakhulu, ukubhuleka kuvame noma kugcwele isikhathi eside ngesikhathi sokusebenza, i-crankshaft izolinyazwa i-torque eyeqile noma umthwalo womthelela. Ngaphezu kwalokho, i-crankshaft ijwayele ukuphuka uma injini kadizili inezingozi ezifana nokugijima, i-ramming kanye ne-valve ejection. Ukuxilongwa kanye nokuxazulula inkinga yokuphuka kwe-crankshaft injini

Ukuze uvimbele ukuphulwa kwe-crankshaft, izinyathelo ezilandelayo zingathathwa ngesikhathi sokulungiswa:

Okokuqala, ngaphambi kokulungisa i-crankshaft, hlola ngokucophelela i-crankshaft ukuze uthole imifantu, unake ngokukhethekile ingxenye yokuguqulwa kwe-fillet, uma kukhona ukuqhekeka, i-shaft kufanele ichithwe. Lapho ugaya ijenali, gcina irediyasi ethile yefillet phakathi kwejenali kanye nengalo ye-crank. Unganciphisi usayizi we-fillet ngokuzenzakalelayo. Naka isiphetho esingaphezulu se-fillet, ngaphandle kwalokho kuzodala ukugxila kwengcindezi futhi kubangele ukuphuka kwe-crankshaft.

Okwesibili, lapho ukuguga kosayizi wejenali kweqa umkhawulo, kuyadingeka ukukhetha indlela enethonya elincane emandleni okukhathala ejenali ukuze alulame. Ukwehliswa kokuqina kukhulu.

Khona-ke, ukucaciswa okufanayo kanye nokuvunyelwa kokuphela kwejenali ngayinye kanye nokuthwala kufanele kuhambisane nezinga. Uma imvume inkulu kakhulu, kulula ukulimaza i-crankshaft ngenxa yomthelela. Uma imvume incane kakhulu, i-crankshaft ingase iphuke ngenxa yokubamba i-shaft. Mayelana nokuhlanganisa, isikhathi sokuvutha kufanele silungiswe kahle, hhayi ngaphambi kwesikhathi kakhulu noma ukuhlehla kakhulu, qaphela ibhalansi ye-crankshaft, i-flywheel ne-clutch.
