Isihlahla esineCrankshaft.
Iithayile ezifakwe kwiibrakethi ezisisigxina ze-crankshaft kunye ne-cylinder block kwaye zidlala indima yokuthwala kunye ne-lubrication zidla ngokubizwa ngokuba yi-crankshaft bearing pads.
Ukuthwala kweCrankshaft ngokuqhelekileyo kwahlulwe kwiindidi ezimbini: ukuthwala kunye nokuthwala i-flanging. Iqokobhe elithwele igophe alikwazi ukuxhasa kuphela kwaye lithambise i-crankshaft, kodwa likwadlala indima yokuma kwe-axial ye-crankshaft.
inotshi
Iinotshi zeetayile ezimbini kufuneka zijongane necala elifanayo, kwaye ukuba intonga yokudibanisa i-bearing bush ikhethekileyo kumacala omabini, amanqaku kwicala lentonga yokudibanisa kufuneka abonakale.
Ukuthwala ubude
Ukuthwala okutsha kulayishwa kumngxuma wokuhlala, kwaye isiphelo ngasinye sesibini esiphezulu nesisezantsi kufuneka sibe ngu-0.03-0.05mm ngaphezu kwenqwelo yokuhlala yokuhlala. Ukuqinisekisa ukuba iqokobhe elithweleyo kunye nomngxuma wesitulo zilingana ngokusondeleyo, phucula isiphumo sokuphelisa ubushushu.
Indlela yokuhlola ubude betyholo elithweleyo kukuba: faka isihlahla esithweleyo, faka isigqubuthelo sesihlahla esithwalayo, uqinise ibholithi enye ngokwexabiso elichaziweyo, faka i-gasket ye-0.05mm ubukhulu phakathi kwesinye isiciko sokugqibela kunye nenqwelomoya yesihlalo sokuthwala, xa i-torque ye-screw end bolt ifikelela kwi-10-20N·m. kwaye isiphelo ngaphandle kokubeka indawo edibeneyo kufuneka ibe yifayile phantsi; Ukuba i-gasket inokukhutshwa, ibonisa ukuba ubude bokuthwala bufanelekile; Ukuba i-gasket ayigxothwanga kwixabiso le-torque elichaziweyo, ayinakucatshulwa, ebonisa ukuba i-bearing bush ifutshane kwaye kufuneka iphinde ikhethwe.
I-tenon egudileyo ngasemva ilungile
Ukuthwala umva kufuneka kungabi nebala, uburhabaxa bomhlaba uRa ngu-0.8μm, i-tenon inokuthintela ukujikeleza kwe-bushing, i-positioning function, njenge-tenon iphantsi kakhulu, ingasetyenziselwa ukuchaphazela ukuphakama okufanelekileyo, njengomonakalo we-tenon, kufuneka iphinde ikhethwe ukuthwala i-bushing.
Ukulingana kwe-elastic ngaphandle kwe-husk
Emva kokubeka i-bearing bush entsha kwisihlalo sokuthwala, i-curvature radius ye-bearing bush iyadingeka ukuba ibe mkhulu kune-curvature radius ye-hole yesihlalo. Xa i-bearing bush ilayishwa kumngxuma wokuhlala, inokufakwa ngokusondeleyo kunye nomngxuma wesihlalo sokuthwala ngentwasahlobo ye-bearing bush ngokwayo ukuququzelela ukutshatyalaliswa kobushushu. Khangela ukuba iqokobhe elithweleyo lisisimumu, unokucofa ngasemva kwiqokobhe elithweleyo ukujonga, kukho isandi esisisimumu sibonisa ukuba i-alloy kunye nepleyiti engezantsi ayinamandla, kufuneka iphinde ikhethwe.
I-gap ehambelanayo yejenali ye-tile ye-shaft kufuneka ifaneleke
Xa igobolondo yokuthwala ikhethiweyo, i-gap ehambelanayo kufuneka ihlolwe. Ngethuba lokuhlolwa, i-cylinder gauge kunye ne-micrometer ilinganisa i-bearing bush kunye nejenali, kwaye umehluko kukukhutshwa okufanelekileyo. Indlela yokuhlola yokucocwa kwesihlahla esithwalayo yile: kuba intonga yokudibanisa, sebenzisa umaleko obhityileyo weoyile kwisihlahla esithwalayo, qinisa intonga yokudibanisa kwijenali ehambelanayo, qinisa ibholithi ngokwexabiso letorque echaziweyo, emva koko ujike intonga yokudibanisa ngesandla, unokujikeleza i-1 ~ 1/2 ukujika, tsala intonga yokudibanisa, akukho nto ihambelana ne-axi; Kwi-crankshaft shingles, sebenzisa i-oyile kumphezulu wentamo ye-shaft nganye kunye neeshingles ezithwele, faka i-crankshaft kwaye uqinise iibholithi ngokwexabiso le-torque echaziweyo, kwaye utsale i-crankshaft ngezandla zombini, ukuze i-crankshaft ikwazi ukujika i-1/2 ukujika, kwaye ukujikeleza kube lula kwaye kufanayo ngaphandle kokuthintela umcimbi.
Indlela efanelekileyo yokufakela i-tile ye-crankshaft
Ufakelo olufanelekileyo lweethayile ze-crankshaft lubandakanya la manyathelo aphambili alandelayo:
Ukufakwa kwe-balance shaft: Faka i-balance shaft kwicala ngalinye le-crankshaft. Ezi shafts zokulinganisa zixhomekeke kwi-oyile yokutshiza ukuze ithambise, endaweni yokuthambisa ngenkani ngempompo yeoli. Ngoko ke, ukulawulwa kwe-gap phakathi kwe-balance shaft kunye negobolondo yokuthwala kubaluleke kakhulu kwaye kufuneka kugcinwe phakathi kwe-0.15- 0.20 mm.
Ukulawulwa kwe-Gap kunye nokulungelelaniswa: Ukuba i-gap ayilula ukulawula, unokusebenzisa kuqala i-fealer ukulinganisa i-gap phakathi kwe-bearing bush kunye ne-balance shaft xa i-bearing bush ingafakwanga kwibhloko ye-cylinder. Umsantsa ocetyiswayo ngu-0.3 mm. Ukuba i-gap ingaphantsi kwe-0.3 mm, ubungakanani obufunekayo bunokufezekiswa ngokukrala okanye ukucwangciswa kwi-lathe ukuqinisekisa ukuba umgangatho wokuphazamiseka phakathi kwe-bush ye-bearing and the bearing hole yi-0.05 mm, kwaye i-gap i malunga ne-0.18 mm emva kokuba i-bush yokuzala ifakwe kwi-bearing hole.
I-Stable Bearing bush: Xa ufaka i-balance shaft ephethe i-bush, i-302AB iglue kufuneka ifakwe ngasemva kwi-bearing bush ukwenzela ukwandisa ukuzinza kwe-bearing bush kunye nokuthintela ukuba ihambe okanye ikhulule.
Ukuthwala indawo kunye nokuthambisa: iqokobhe ngalinye elithweleyo lineqhuqhuva lokumisa, ekufuneka lincanyatheliswe kwindawo yokubeka indawo kwibhloko yesilinda. Ngexesha elifanayo, qinisekisa ukuba i-oil passage hole kwi-bearing ihambelana ne-oyile ye-oyile kwibhloko ye-cylinder ukwenzela ukuseka inkqubo yokuthambisa.
Ufakelo lwekhava yokuthwala: Emva kokufaka isigqubuthelo sokuqala, jika i-crankshaft ukuqinisekisa ukuba akukho nto ibambekayo. Faka i-cap yokuthwala kwaye uyiqinise ngokweenkcukacha. Oku kwenziwa kumnqwazi ngamnye wokuthwala. Ukuba i-bearing cap ibambekile, ingxaki inokuba kwi-bearing cap okanye kwi-bearing part. Susa kwaye ujonge ii-burrs okanye ukulingana okungafanelekanga kwesitulo sokuthwala.
Ngokulandela la manyathelo, unokuqinisekisa ukufakwa ngokufanelekileyo kweetayile ze-crankshaft kwaye ugweme ukungaphumeleli komatshini ngenxa yofakelo olungafanelekanga.
