Isihlahla esithwala i-crankshaft.
Amathayili afakwe kuma-bracket aqinile e-crankshaft kanye ne-cylinder block futhi adlala indima yokuthwala kanye nokugcoba ngokuvamile abizwa ngokuthi ama-crankshaft bearing pads.
Ukuthwala kwe-crankshaft ngokuvamile kuhlukaniswe izinhlobo ezimbili: ukuthwala kanye nokuthwala kwe-flanging. Igobolondo lokuthwala eli-flanged alikwazi nje ukusekela nokugcoba i-crankshaft, kodwa futhi lidlala indima yokubeka i-axial ye-crankshaft.
i-notch
Izimbobo zamathayili amabili kufanele zibheke ohlangothini olufanayo, futhi uma isihlahla esithwala induku yokuxhuma sikhethekile kuzo zombili izinhlangothi, kufanele kubonakale izimpawu ohlangothini lwenduku yokuxhuma.
Ubude bebheyari
Ibhereyi entsha ifakwa emgodini wesihlalo, futhi ukuphela ngakunye kwezingcezu ezimbili eziphezulu nezingezansi kufanele kube phezulu ngo-0.03-0.05mm kunesihlalo sebhereyi. Ukuqinisekisa ukuthi igobolondo lebhereyi kanye nembobo yesihlalo kuhambisana kahle, thuthukisa umphumela wokushabalalisa ukushisa.
Indlela yokuhlola ubude besihlahla sokuthwala yile: faka isihlahla sokuthwala, faka isembozo sesihlahla sokuthwala, qinisa ibholidi elilodwa elisekugcineni ngokwenani le-torque elicacisiwe, faka i-gasket enobukhulu obungu-0.05mm phakathi kwesinye isembozo sokugcina kanye nesihlalo sesihlahla sokuthwala, lapho i-torque yebholidi lesikulufo ifinyelela ku-10-20N·m, uma i-gasket ingenakukwazi ukukhishwa, ikhombisa ukuthi ubude be-bearing bude kakhulu, futhi isiphetho ngaphandle kokubeka ijoyinti kufanele sifakwe phansi; Uma i-gasket ingakhishwa, ikhombisa ukuthi ubude be-bearing buyafaneleka; Uma i-gasket ingafakwanga isikulufo enanini le-torque elicacisiwe, ayikwazi ukukhishwa, okubonisa ukuthi isihlahla sokuthwala sifushane kakhulu futhi kufanele sikhethwe kabusha.
Umhlane obushelelezi we-tenon muhle
I-bearing back kufanele ingabi nabala, ubulukhuni bomphezulu i-Ra ingu-0.8μm, i-tenon ingavimbela ukujikeleza kwe-bearing bushing, umsebenzi wokubeka, njenge-tenon uphansi kakhulu, ungasetshenziswa ukuphazamisa ukuphakama okufanele, njengomonakalo we-tenon, kufanele kukhethwe kabusha i-bearing bushing.
Ukulingana okunwebekayo ngaphandle kwe-husk
Ngemva kokubeka isihlahla esisha sokuthwala esihlalweni sokuthwala, irediyasi egobile yesihlahla sokuthwala iyadingeka ibe nkulu kunerediyasi egobile yembobo yesihlalo. Lapho isihlahla sokuthwala silayishwa emgodini wesihlalo, singafakwa eduze nembobo yesihlalo sokuthwala ngasentwasahlobo yesihlahla sokuthwala uqobo ukuze kube lula ukushabalalisa ukushisa. Hlola ukuthi igobolondo lokuthwala aliqinile yini, ungathinta ngemuva kwegobolondo lokuthwala ukuze uhlole, kukhona umsindo ongapheli obonisa ukuthi ingxubevange kanye nepuleti elingezansi akuqinile, kufanele kukhethwe kabusha.
Isikhala esifanelana nejenali yethayela lomgodi kufanele sifaneleke
Uma kukhethwa igobolondo lokuthwala, igebe elihambisanayo kumele lihlolwe. Ngesikhathi sokuhlola, igeyiji yesilinda kanye ne-micrometer kulinganisa isihlahla sokuthwala kanye nejenali, futhi umehluko uwukuthi igebe lifanelekile. Indlela yokuhlola yokuhla kwesihlahla sokuthwala yile: ngenduku yokuxhuma, faka ungqimba oluncane lwamafutha esihlahleni sokuthwala, qinisa induku yokuxhuma kujenali ehambisanayo, qinisa ibholidi ngokwenani le-torque elicacisiwe, bese ushwiba induku yokuxhuma ngesandla, ungazungeza ukujika okungu-1 ~ 1/2, udonse induku yokuxhuma eceleni kwe-axis, akukho muzwa wegebe, okungukuthi, ukuhlangabezana nezidingo; Ngama-shingle e-crankshaft, faka i-oyili ebusweni bentamo ngayinye yomgodi kanye nama-shingle e-bearing, faka i-crankshaft bese uqinisa amabholidi ngokwenani le-torque elicacisiwe, bese udonsa i-crankshaft ngezandla zombili, ukuze i-crankshaft ikwazi ukujika okungu-1/2, futhi ukujikeleza kube lula futhi kufane ngaphandle kokuvimba.
Indlela efanele yokufaka ithayela le-crankshaft
Ukufakwa okufanele kwamathayela e-crankshaft kuhlanganisa izinyathelo ezilandelayo ezibalulekile:
Ukufakwa kwe-balance shaft: Faka i-balance shaft ohlangothini ngalunye lwe-crankshaft. Lawa ma-balance shaft athembele ku-splash oil ukuze agcotshwe, kunokuba agcotshwe ngenkani ngepompo kawoyela. Ngakho-ke, ukulawulwa kwegebe phakathi kwe-balance shaft kanye ne-bearing shell kubaluleke kakhulu futhi kufanele kugcinwe phakathi kuka-0.15-0.20 mm.
Ukulawula igebe nokulungisa: Uma igebe lingekho lula ukulilawula, ungasebenzisa i-feeler kuqala ukukala igebe eliphakathi kwesihlahla sokuthwala kanye nomgodi wokulinganisela lapho isihlahla sokuthwala singakafakwanga ku-cylinder block. Igebe elinconywayo lingu-0.3 mm. Uma igebe lingaphansi kuka-0.3 mm, usayizi odingekayo ungafinyelelwa ngokuklwebha noma ngomshini ku-lathe ukuqinisekisa ukuthi izinga lokuphazamiseka phakathi kwesihlahla sokuthwala kanye nomgodi wokuthwala lingu-0.05 mm, kanti igebe lingaba ngu-0.18 mm ngemva kokuba isihlahla sokuthwala sifakwe emgodini wokuthwala.
Isihlahla esiqinile sokuthwala: Uma ufaka isihlahla esiqinile sokuthwala, kufanele ufake iglue engu-302AB ngemuva kwesihlahla esiqinile ukuze kuqiniswe ukuzinza kwesihlahla esiqinile futhi kuvimbele ukuthi singanyakazi noma sixegiswe.
Indawo yokubeka amabhereyi kanye nokugcotshwa: igobolondo ngalinye lokubeka amabhereyi line-positioning bump, okufanele ifakwe endaweni yokubeka amabhereyi ebhulokini lesilinda. Ngesikhathi esifanayo, qiniseka ukuthi imbobo yokudlula uwoyela ebhereyishini ihambisana nendawo yokudlula uwoyela ebhulokini lesilinda ukuze kusungulwe uhlelo lokugcoba.
Ukufakwa kwesembozo samabhereyi: Ngemva kokufaka isembozo sokuqala samabhereyi, phendula i-crankshaft ukuqinisekisa ukuthi akukho okubambekile. Faka isivalo samabhereyi bese usiqinisa ngokwemigomo. Lokhu kwenziwa ngesembozo ngasinye samabhereyi. Uma isivalo samabhereyi sibambekile, inkinga ingaba sesesivalo samabhereyi noma engxenyeni yamabhereyi. Susa bese uhlola ukuthi azikho yini izimbobo noma ukulingana okungafanele kwesihlalo samabhereyi.
Ngokulandela lezi zinyathelo, ungaqinisekisa ukufakwa okufanele kwamathayela e-crankshaft futhi ugweme ukwehluleka kwemishini ngenxa yokufakwa okungafanele.
