Isihlahla esine-Crankshaft.
Amathayela afakwe kubakaki abangaguquki be-crankshaft nesilinda block futhi adlala indima yokuthwala nokugcoba ngokuvamile abizwa ngokuthi ama-crankshaft bearing pads.
Ukuzala kwe-Crankshaft kuvame ukuhlukaniswa ngezinhlobo ezimbili: ukuthwala kanye ne-flanging. Igobolondo eliphethe i-flanged alikwazi ukusekela kuphela futhi ligcobe i-crankshaft, kodwa futhi lidlale indima yokuma kwe-axial ye-crankshaft.
inothi
Ama-notches ama-tile amabili kufanele abhekane nohlangothi olufanayo, futhi uma isihlahla esithwala induku yokuxhuma sikhethekile ezinhlangothini zombili, amamaki ohlangothini lwenduku yokuxhuma kufanele abonakale.
Ubude bokuzala
I-bearing entsha ilayishwa emgodini wesihlalo, futhi umkhawulo ngamunye wezingcezu ezimbili ezingenhla nezingezansi kufanele zibe ngu-0.03-0.05mm ngaphezu kwendiza yesihlalo esiphethe. Ukuqinisekisa ukuthi igobolondo elithwele kanye nembobo yesihlalo kuyalingana eduze, thuthukisa umphumela wokuqeda ukushisa.
Indlela yokuhlola ubude besihlahla esithwalayo yile: faka isihlahla esithwalayo, faka isembozo sesihlahla esithwalayo, qinisa ibhawudo elilodwa ngokwenani le-torque elishiwo, faka i-gasket engu-0.05mm ukushuba phakathi kwesinye isembozo nesiphetho. indiza yesihlalo sehlathi, lapho i-torque ye-screw end bolt ifinyelela ku-10-20N · m, uma i-gasket ingakwazi ukukhishwa, ibonisa ukuthi ubude bokuthwala bude kakhulu, futhi ukuphela ngaphandle kokubeka ngokuhlanganyela kufanele kube ifayela phansi; Uma i-gasket ingakhishwa, ibonisa ukuthi ubude bokuthwala bufanelekile; Uma i-gasket ingajikisiwe enanini le-torque elishiwo, ayikwazi ukukhishwa, okubonisa ukuthi isihlahla esithwalayo sifushane kakhulu futhi kufanele siphinde sikhethwe.
I-back tenon enhle
Ukuhlehla kufanele kungabi namabala, ubuhwaqane be-Ra bungu-0.8μm, i-tenon ingavimbela ukujikeleza kwe-bushing, umsebenzi wokumisa, njenge-tenon uphansi kakhulu, ungasetshenziswa ukuze uthinte ukuphakama okufanelekile, njengokulimala kwe-tenon, kufanele kuphindwe kabusha i-bearing bushing ekhethiwe.
Ukulingana kwe-elastic ngaphandle kwamakhoba
Ngemuva kokubeka isihlahla esisha esithwalayo esihlalweni esithwalayo, i-curvature radius yesihlahla esithwalayo iyadingeka ukuba ibe nkulu kune-curvature radius yembobo yokuhlala. Lapho isihlahla esithwalayo silayishwa emgodini wesihlalo, singafakwa eduze nembobo yesihlalo sokuthwala ngentwasahlobo yesihlahla esithwalayo ngokwaso ukuze kube lula ukuchithwa kokushisa. Hlola ukuthi igobolondo elithwalayo liyisimungulu, ungathepha ngemuva kwegobolondo elithwalayo ukuze uhlole, kunomsindo oyisimungulu obonisa ukuthi i-alloy nepuleti eliphansi aliqinile, kufanele liphinde likhethwe.
Igebe elihambisanayo lejenali yethayela ye-shaft kufanele ifaneleke
Lapho igobolondo elithwalayo likhethiwe, igebe elihambisanayo kufanele lihlolwe. Ngesikhathi sokuhlolwa, i-cylinder gauge kanye ne-micrometer ikala isihlahla esithwalayo kanye nejenali, futhi umehluko ukuvunyelwa okufanelekile. Indlela yokuhlola yokucaciswa kwesihlahla esithwalayo yilena: kwinduku yokuxhuma, sebenzisa ungqimba oluncane lwamafutha esihlahleni esithwalayo, qinisa induku yokuxhuma kujenali ehambisanayo, qinisa ibhawodi ngokwenani le-torque elishiwo, bese ujika. induku yokuxhuma ngesandla, ingazungeza ukuphenduka okungu-1 ~ 1/2, idonse induku yokuxhuma eduze kokuqondisa kwe-eksisi, akukho ukuzwa kwegebe, okungukuthi, ukuhlangabezana nezidingo; Kuma-crankshaft shingles, gcoba uwoyela phezu kwentamo ye-shaft ngayinye kanye nama-shingles athwele, faka i-crankshaft bese uqinisa amabhawodi ngokwenani le-torque elishiwo, bese udonsa i-crankshaft ngezandla zombili, ukuze i-crankshaft ikwazi ukuphenduka 1/2, futhi ukujikeleza kukhanya futhi kufanayo ngaphandle kokuvimbela ukwenzeka.
Indlela efanele yokufaka i-crankshaft tile
Ukufakwa kahle kwamathayili e-crankshaft kuhlanganisa lezi zinyathelo ezibalulekile ezilandelayo:
Ukufakwa kwe-balance shaft: Faka i-balance shaft ohlangothini ngalunye lwe-crankshaft. Lawa mashafu ebhalansi ancike kuwoyela ochaphazayo ukuze kugcotshiswe, kunokuba kugcotshwe ngempoqo ngepompo likawoyela. Ngakho-ke, ukulawulwa kwegebe phakathi kwe-balance shaft kanye negobolondo elithwalayo kubaluleke kakhulu futhi kufanele kugcinwe phakathi kuka-0.15- 0.20 mm.
Ukulawula igebe kanye nokulungiswa: Uma igebe lingelula ukulilawula, ungasebenzisa okokuqala i-fealer ukukala igebe phakathi kwesihlahla esithwalayo kanye ne-balance shaft lapho isihlahla esithwalayo singakafakwa ku-cylinder block. Igebe elinconyiwe lingu-0.3 mm. Uma igebe lingaphansi kuka-0.3 mm, ubukhulu obudingekayo bungafinyelelwa ngokuklwebha noma ngomshini ku-lathe ukuze kuqinisekiswe ukuthi izinga lokuphazanyiswa phakathi kwesihlahla esithwalayo kanye nembobo yokubhoboza lingu-0.05 mm, futhi igebe lingaba ngu-0.18 mm ngemva kokuthwala. isihlahla sithelwa emgodini wokuzala.
Isihlahla esithwalayo esizinzile: Lapho ufaka isihlahla esithwala i-balance shaft, iglue engu-302AB kufanele ifakwe ngemuva kwesihlahla esithwalayo ukuze kwandiswe ukuqina kwesihlahla esithwalayo futhi sivimbele ukuthi singanyakazi noma sixege.
Ukubeka indawo kanye nokugcoba: igobolondo ngalinye eliphethe lineqhuqhuva, okufanele linamathele endaweni yokuma kubhulokhi yesilinda. Ngesikhathi esifanayo, qiniseka ukuthi imbobo yokudlula uwoyela ku-bearing ihambisana nephaseji kawoyela ku-cylinder block ukuze kusungulwe uhlelo lokuthambisa.
Ukufakwa kwekhava elinophawu: Ngemva kokufaka ikhava yokuqala, vula i-crankshaft ukuze uqiniseke ukuthi akukho okubambekayo. Faka i-bearing cap futhi uyiqinise ngokuvumelana nencazelo. Lokhu kwenzelwa i-cap ngayinye yokuthwala. Uma ikepisi elithwalayo libambekile, inkinga ingase ibe kukepisi lokuthwala noma engxenyeni yokuthwala. Susa futhi uhlole ama-burrs noma ukulingana okungafanele kwesihlalo sokuthwala.
Ngokulandela lezi zinyathelo, ungaqinisekisa ukufakwa kahle kwamathayili e-crankshaft futhi ugweme ukwehluleka komshini ngenxa yokufakwa okungafanele.
