Crankshaft ethwele isihlahla.
Amathayili abekwe kubakaki abahleliwe be-crankshaft ne-cylinder block futhi adlale indima yokuthwala nokuthambisa okuvame ukubizwa ngokuthi ama-crankshaft athela amaphakethe.
I-Crankshaft ethwala imvamisa ihlukaniswe izinhlobo ezimbili: ukuthwala nokuthwala okuvuthayo. Igobolondo elinomthwalo ovuthayo alikwazi ukusekela futhi luthambe i-crankshaft, kepha futhi lidlale indima yokuma kwe-axial of the crankshaft.
ugch
Ama-notches amathayili womabili kufanele abhekane nohlangothi olufanayo, futhi uma i-Connecting Rood ethwala isihlahla ikhethekile ezinhlangothini zombili, amamaki ohlangothini lwenduku yokuxhuma kufanele abonakale.
Ubude bokuthwala
Umthamo omusha ulayishwe emgodini wesihlalo, futhi ukuphela kwengxenye ngayinye yezingcezu ezimbili ezingenhla nezingaphansi kufanele kube ngu-0.03-0.05mm ephakeme kunendiza yesihlalo esibekile. Ukuqinisekisa ukuthi igobolondo elithwala kanye nomgodi wesihlalo ulungile, thuthukisa umphumela wokuhlanza ukushisa.
Indlela enamandla yokuhlola ubude besihlahla esivunayo yile: Faka isihlahla esivuzayo, faka isikhafu esinezihlahla ezivumayo, lapho i-torque yesihlahla esisezingeni eliphakeme, uma i-torque yesihlahla se-screw bolt ifinyelela ku-10-20n. isikhathi eside, futhi ukuphela ngaphandle kokubamba okuhlangene kufanele kufakwe phansi; Uma i-gasket ingakhishwa, kukhombisa ukuthi ubude obubhekele bufanele; Uma i-gasket ingahlelwe ngenani le-torque ebekiwe, ayikwazi ukukhishwa, okukhombisa ukuthi isihlahla esivunayo sifushane kakhulu futhi kufanele sikhethwe kabusha.
Bushelelezi emuva tenon okuhle
Ukubuyela emuva kufanele kube yi-poloy-free, i-raughness raughness ra engu-0,8μm, i-tenon ingavimbela ukuhambisa i-bushing, umsebenzi wokubeka isikhundla, njenge-tenon iphansi kakhulu, ingahle isetshenziswe ukuphakama okuphezulu kakhulu, okufana nokulimala kwe-tenon, kufanele kukhethwe kabusha i-butheng.
I-Elastic fit ngaphandle kwe-husk
Ngemuva kokubeka isihlahla esisha esisehlathini esihlalweni esivunayo, i-curvatun radius yesihlahla esivuzayo iyadingeka ukuba ibe mkhulu kune-radivay yokuhlaselwa komgodi wesihlalo. Lapho isihlahla esivuzayo silayishwe emgodini wesihlalo, singase sihlanganiswe nomgodi wesihlalo esivuzayo ngentwasahlobo yesihlahla esivunayo ukuze sikwazi ukwenza lula ukushiyeka kokushisa ukuze kube lula ukufethina kokushisa. Bheka ukuthi i-bearing igobolondo iyizimungulu, ungathepha emuva kwegobolondo elivunayo ukuze uhlole, kunomsindo oyisimungulu ukhombisa ukuthi ipuleti nepuleti elingaphansi alinamandla, kufanele liqashelwe kabusha.
Igebe elifanayo lejele le-shaft tile:
Lapho kukhethwe igobolondo elivuthayo, igebe elifanayo kufanele lihlolwe. Ngesikhathi sokuhlola, i-cylinder gauge kanye ne-micrometer ukukala isihlahla esivuzayo kanye nephephabhuku, kanye nomehluko ukukhishwa okufanele. Indlela yokuhlola yokuvunyelwa kwesihlahla esivunayo yilena: Ngenduku yokuxhuma, faka ungqimba oluncanyana lwamafutha esihlahleni esivumayo, bese ushintsha i-turment ngenani elihambisanayo, ungashintsha i-Connecting Rod ngesandla, bese ushintsha i-Concuration REALTS nge-Assue Direction, akukho mbono wegebe, okungukuthi, ahlangabezane nezidingo; Okwe-crankshaft shingles, faka uwoyela ngaphezulu kwentamo ngayinye ye-shaft futhi ufake ama-shingles, faka ama-crankshaft bese uqinisa ama-crankshaft abheke ukuphenduka okungu-1/2.
Indlela efanele yokufaka ye-crankshaft tile
Ukufakwa okufanele kwama-trankshaft tile kufaka phakathi izinyathelo ezilandelayo ezilandelayo:
Ukufakwa kwe-Balance Shaft: Faka shaft esele ohlangothini ngalunye lwe-crankshaft. Le mishini yokulinganisa ithembele kumafutha okugcoba ukuthambisa, kunokuba inyuswe i-lubricution ngepompo kawoyela. Ngakho-ke, ukulawula kwegebe phakathi kwe-banking shaft kanye negobolondo elithwala libaluleke kakhulu futhi kufanele ligcinwe phakathi kuka-0.15- 0,20 mm.
Igebe lokulawula nokulungiswa: Uma igebe akulula ukulawula, ungaqala ukusebenzisa umhawu ukukala igebe phakathi kwesihlahla esivunayo kanye ne-bush yebhalansi lapho i-bush evuthayo ingafakwanga kwi-cylinder block. Igebe elinconyiwe lingu-0,3 mm. Uma igebe lingaphansi kuka-0,3 mm, usayizi odingekayo ungatholakala ngokuhlasela noma ngokufaka imishini ku-lathe okulinganiselwe phakathi kwesihlahla esivunayo kanye ne-groung ngemuva kokuthi isihlahla esingu-0.08 mm ngemuva kokutholwa isihlahla esivuzayo.
Isihlahla esizinzile esizinzile
Ukubeka indawo nokuthambisa: Igobolondo ngalinye elithwala line-bump yokubeka isikhundla, okufanele libambelele esimweni sokuma esihlalweni esiku-cylinder block. Ngasikhathi sinye, qiniseka ukuthi umgodi wokuma kawoyela ekuvumeni uqondaniswe nendima kawoyela kwi-cylinder block ukuze usungule uhlelo lokuthambisa.
Ukufakwa Kwesembozo: Ngemuva kokufaka isembozo sokuqala sokuthwala, vula i-crankshaft ukuze uqiniseke ukuthi akukho okunamathele. Faka i-cap evunayo bese uqinisa ngokusho kwencazelo. Lokhu kwenziwa nge-cap ye-bearing ngayinye. Uma i-cap ethwala ibambeke, inkinga ingaba se-cap ephethe noma engxenyeni ethwala. Susa futhi uhlole ama-burrs noma i-FAID efanelekile yesihlalo sokuthwala.
Ngokulandela lezi zinyathelo, ungaqinisekisa ukufakwa okufanele kwamathayela we-crankshaft futhi uvikele ukwehluleka kwemishini ngenxa yokufakwa okungafanele.
