Chitsamba chokhala ndi Crankshaft.
Ma matailosi omwe amaikidwa pamabulaketi okhazikika a crankshaft ndi cylinder block ndipo amasewera ndi kunyamula mafuta nthawi zambiri amatchedwa ma crankshaft bearing pads.
Kunyamula crankshaft nthawi zambiri kugawidwa m'mitundu iwiri: yonyamula ndi yonyamula. Chipolopolo chokhala ndi flanged sichingangothandizira ndikuyika mafuta pa crankshaft, komanso kuchita nawo gawo la axial positioning of crankshaft.
mphako
Nsonga za matailosi awiriwo ziyenera kuyang'anizana ndi mbali imodzi, ndipo ngati ndodo yolumikizira chitsamba ndi yapadera kumbali zonse ziwiri, zizindikiro kumbali ya ndodo yolumikizira ziyenera kuwoneka.
Kubereka kutalika
Kunyamula kwatsopano kumayikidwa mu dzenje la mpando, ndipo mapeto aliwonse a zidutswa ziwiri zapamwamba ndi zapansi ziyenera kukhala 0.03-0.05mm kuposa ndege yonyamula mpando. Kuonetsetsa kuti chipolopolo ndi dzenje la mpando zikugwirizana kwambiri, sinthani kutentha kwa mpweya.
Njira yoyeserera yowonera kutalika kwa chitsamba chonyamula ndi: ikani chitsamba chonyamula, ikani chivundikiro cha chitsamba, limbitsani bawuti imodzi molingana ndi mtengo womwe watchulidwa, ikani gasket ya makulidwe a 0.05mm pakati pa chivundikiro china ndi chonyamula. chitsamba mpando ndege, pamene makokedwe a wononga bawuti mapeto kufika 10-20N · m'ma, ngati gasket sangathe yotengedwa, zimasonyeza kuti kubala kutalika ndi yaitali kwambiri, ndipo mapeto popanda udindo olowa ayenera wapamwamba pansi; Ngati gasket ikhoza kuchotsedwa, imasonyeza kuti kutalika kwake kuli koyenera; Ngati gasketyo siikulungidwa pamtengo womwe watchulidwa, sungathe kuchotsedwa, kusonyeza kuti chitsamba chonyamula ndi chachifupi kwambiri ndipo chiyenera kusankhidwanso.
Tenon yosalala bwino
Kubweza kuyenera kukhala kopanda banga, roughness pamwamba Ra ndi 0.8μm, tenon imatha kuletsa kusuntha kwa bushing, kuyimitsa ntchito, monga tenon ndiyotsika kwambiri, kungagwiritsidwe ntchito kukhudza kutalika koyenera, monga kuwonongeka kwa tenon, kuyenera kubwezeretsedwanso. osankhidwa kubala bushing.
Elastic fit popanda mankhusu
Pambuyo poyika chitsamba chatsopanocho pampando wonyamula, mtunda wokhotakhota wa chitsamba choberekera umayenera kukhala wamkulu kuposa utali wopindika wa dzenje la mpando. Pamene chitsamba chonyamulira chimayikidwa mu dzenje la mpando, chikhoza kulumikizidwa kwambiri ndi dzenje la mpando wonyamula ndi kasupe wa chitsamba chokha kuti chiwongolere kutentha. Yang'anani ngati chipolopolo chonyamulira ndi chosayankhula, mutha kugogoda kumbuyo kwa chipolopolo chonyamulira kuti muwone, pali mawu osayankhula akuwonetsa kuti aloyi ndi mbale yapansi si yamphamvu, iyenera kusankhidwanso.
Kusiyana kofananira kwa pepala la shaft tile kuyenera kukhala koyenera
Pamene chipolopolo chonyamula chikusankhidwa, kusiyana kofananira kuyenera kufufuzidwa. Poyang'anira, silinda yoyezera ndi micrometer imayeza chitsamba chonyamula ndi magazini, ndipo kusiyana kwake ndikuloledwa koyenera. Njira yowunikira yochotsera chitsamba chonyamulira ndi: kwa ndodo yolumikizira, ikani mafuta ochepa pa chitsamba chonyamula, limbitsani ndodo yolumikizira pamagazini yofananira, limbitsani bawuti molingana ndi mtengo womwe watchulidwa, ndiyeno gwedezani. ndodo yolumikizira ndi dzanja, imatha kuzungulira 1 ~ 1/2 kutembenuka, kukoka ndodo yolumikizira motsatira njira ya olamulira, palibe kumverera kwapakati, ndiko kuti, kukwaniritsa zofunikira; Pa crankshaft shingles, thira mafuta pamwamba pa khosi lililonse la shaft ndi ma shingles, ikani crankshaft ndikumangitsa ma bolts molingana ndi mtengo womwe watchulidwa, ndikukoka crankshaft ndi manja onse awiri, kuti crankshaft itembenuke 1/2 kutembenuka, ndipo kuzungulira kumakhala kopepuka komanso kofanana popanda kutsekereza chodabwitsa.
Njira yoyenera yoyika matayala a crankshaft
Kuyika bwino kwa matailosi a crankshaft kumaphatikizapo izi:
Kuyika shaft yowerengera: Ikani shaft yoyendera mbali zonse za crankshaft. Ma shafts awa amadalira mafuta opaka mafuta kuti azipaka mafuta, m'malo mokakamiza kudzoza kudzera pa pampu yamafuta. Chifukwa chake, kuwongolera kwapakati pakati pa shaft ndi chipolopolo chonyamula ndikofunikira kwambiri ndipo kuyenera kusungidwa pakati pa 0.15-0.20 mm.
Kuwongolera ndi kusintha kwa kusiyana: Ngati kusiyana sikuli kophweka kuwongolera, mutha kugwiritsa ntchito chomverera poyamba kuyeza kusiyana pakati pa chitsamba chonyamulira ndi shaft yotsalira pomwe chitsamba chonyamula sichinayikidwe pa cylinder block. Kusiyana kovomerezeka ndi 0.3 mm. Ngati kusiyana kuli kosakwana 0.3 mm, kukula kofunikira kungapezeke mwa kukanda kapena makina pa lathe kuonetsetsa kuti mulingo wosokoneza pakati pa chitsamba ndi dzenje ndi 0.05 mm, ndipo kusiyana kuli pafupifupi 0,18 mm pambuyo pa kubereka. chitsamba chimayikidwa mu dzenje.
Chitsamba cholimba chokhazikika: Mukayika chitsamba chokhala ndi shaft, guluu wa 302AB uyenera kuyikidwa kumbuyo kwa chitsamba chonyamulira kuti chitsambacho chisasunthike chisasunthike ndikuchiletsa kusuntha kapena kumasuka.
Pokhala ndi malo ndi mafuta: chipolopolo chilichonse chimakhala ndi chotupa, chomwe chimayenera kumangika pamalo oyika pa silinda. Panthawi imodzimodziyo, onetsetsani kuti bowo la mafuta muzitsulo likugwirizana ndi njira ya mafuta mu cylinder block kuti akhazikitse dongosolo lopaka mafuta.
Kuyika chivundikiro chonyamula: Mukayika chivundikiro choyamba, tembenuzirani crankshaft kuti muwonetsetse kuti palibe chomata. Ikani kapu yonyamula ndikuyimitsa molingana ndi momwe mukufunira. Izi zimachitika pa kapu iliyonse yonyamula. Ngati chipewa chonyamula chikakamira, vuto likhoza kukhala mu kapu kapena mu gawo lonyamula. Chotsani ndikuyang'ana ma burrs kapena malo osayenera a mpando.
Potsatira izi, mutha kuwonetsetsa kuyika bwino kwa matailosi a crankshaft ndikupewa kulephera kwamakina chifukwa choyika molakwika.
Ngati mukufuna kudziwa zambiri, pitilizani kuwerenga zolemba zina patsamba lino!
Chonde tiyimbireni ngati mukufuna zinthu zotere.
