Chitsamba chonyamula crankshaft.
Matailosi omwe amaikidwa pa mabulaketi okhazikika a crankshaft ndi cylinder block ndipo amachita gawo la kuberekera ndi kudzola nthawi zambiri amatchedwa ma crankshaft bearing pads.
Chogwirira cha crankshaft nthawi zambiri chimagawidwa m'mitundu iwiri: chogwirira ndi chogwirira. Chipolopolo cha flanged bearing sichimangothandiza ndi kudzola mafuta pa crankshaft, komanso chimagwira ntchito ngati malo ozungulira a crankshaft.
chiboliboli
Ma kroki a matailosi awiriwa ayenera kuyang'ana mbali imodzi, ndipo ngati chitsamba cholumikizira ndodo chili chapadera mbali zonse ziwiri, zizindikiro zomwe zili mbali ya ndodo yolumikizira ziyenera kuwoneka.
Kutalika kwa bere
Bearing yatsopano imayikidwa mu dzenje la mpando, ndipo mbali iliyonse ya zidutswa ziwiri zapamwamba ndi zapansi ziyenera kukhala zazitali ndi 0.03-0.05mm kuposa malo oimikapo mpando. Kuti muwonetsetse kuti chipolopolo cha bearing ndi dzenje la mpando zikugwirizana bwino, onjezerani mphamvu yotaya kutentha.
Njira yoyesera yowunikira kutalika kwa chitsamba chonyamula katundu ndi iyi: kukhazikitsa chitsamba chonyamula katundu, kukhazikitsa chivundikiro cha chitsamba chonyamula katundu, kulimbitsa bolt imodzi yomaliza malinga ndi mtengo wotchulidwa wa torque, kuyika gasket ya makulidwe a 0.05mm pakati pa chivundikiro china ndi malo oimikapo chitsamba chonyamula katundu, pamene mphamvu ya bolt yonyamula katundu ifika pa 10-20N·m, ngati gasket singachotsedwe, zimasonyeza kuti kutalika kwa chitsamba ndi yayitali kwambiri, ndipo mapeto osayika malo olumikizirana ayenera kuyikidwa pansi; Ngati gasket ingachotsedwe, zimasonyeza kuti kutalika kwa chitsamba ndikoyenera; Ngati gasket sinakulungidwe pamtengo wotchulidwa wa torque, singachotsedwe, zimasonyeza kuti chitsamba chonyamula katundu ndi chachifupi kwambiri ndipo chiyenera kusankhidwanso.
Tenon yosalala bwino
Bearing back iyenera kukhala yopanda banga, Ra yolimba pamwamba ndi 0.8μm, tenon imatha kuletsa kuzungulira kwa bearing bushing, ntchito yoyikira, monga tenon ndi yotsika kwambiri, ingagwiritsidwe ntchito kukhudza kutalika koyenera, monga kuwonongeka kwa tenon, iyenera kusankhidwanso.
Kugwirana kosalala popanda khungwa
Mukayika chitsamba chatsopano choberekera pa mpando woberekera, utali wozungulira wa chitsamba choberekera umafunika kukhala waukulu kuposa utali wozungulira wa dzenje la mpando. Chitsamba choberekera chikalowetsedwa m'dzenje la mpando, chikhoza kuyikidwa pafupi ndi dzenje la mpando woberekera pafupi ndi kasupe wa chitsamba choberekera kuti chizitha kutentha. Onani ngati chipolopolo choberekera chili chopanda pake, mutha kugogoda kumbuyo kwa chipolopolo choberekera kuti muwone ngati pali phokoso lopanda pake lomwe limasonyeza kuti aloyi ndi mbale yapansi sizolimba, ziyenera kusankhidwanso.
Mpata wofanana wa shaft tile journal uyenera kukhala woyenera
Chipolopolo cha bearing chikasankhidwa, mpata wofanana uyenera kufufuzidwa. Pakuwunika, silinda ndi micrometer zimayesa bearing bush ndi journal, ndipo kusiyana kwake ndi kuyenera kwa malo. Njira yowunikira malo a bearing bush ndi iyi: pa ndodo yolumikizira, ikani mafuta ochepa pa bearing bush, imangitsani ndodo yolumikizira pa journal yogwirizana, imangitsani bolt malinga ndi torque yomwe yatchulidwa, kenako gwedezani ndodo yolumikizira ndi dzanja, mutha kuzungulira 1 ~ 1/2, kukoka ndodo yolumikizira motsatira axis, palibe kumverera kwa mpata, ndiko kuti, kukwaniritsa zofunikira; Pa crankshaft shingles, ikani mafuta pamwamba pa khosi lililonse la shaft ndi bearing shingles, ikani crankshaft ndikulimbitsa mabolts malinga ndi torque yomwe yatchulidwa, ndikukoka crankshaft ndi manja onse awiri, kuti crankshaft itembenuke 1/2, ndipo kuzungulirako kukhale kopepuka komanso kofanana popanda kuletsa.
Njira yoyenera yokhazikitsira matailosi a crankshaft
Kukhazikitsa bwino matailosi a crankshaft kumaphatikizapo njira zofunika izi:
Kukhazikitsa shaft yolinganiza: Ikani shaft yolinganiza mbali zonse za crankshaft. Ma shaft olinganizawa amadalira mafuta opopera kuti azitha kudzola, m'malo mogwiritsa ntchito mafuta okakamiza kudzera mu pampu yamafuta. Chifukwa chake, kuwongolera mpata pakati pa shaft yolinganiza ndi chipolopolo cha bearing ndikofunikira kwambiri ndipo kuyenera kusungidwa pakati pa 0.15-0.20 mm.
Kuwongolera ndi kusintha kwa mipata: Ngati mipata sikophweka kuilamulira, choyamba mungagwiritse ntchito chofewetsera kuti muyese mipata pakati pa chitsamba choberekera ndi shaft yolinganiza pamene chitsamba choberekera sichinakhazikitsidwe pa silinda. Mipata yoyenera ndi 0.3 mm. Ngati mipata ili yochepera 0.3 mm, kukula kofunikira kungapezeke mwa kukanda kapena kupangira makina pa lathe kuti muwonetsetse kuti muyezo wosokoneza pakati pa chitsamba choberekera ndi dzenje loberekera ndi 0.05 mm, ndipo mipata ili pafupifupi 0.18 mm chitsamba choberekera chitalowetsedwa mu dzenje loberekera.
Chitsamba chokhazikika: Mukayika chitsamba chokhazikika, guluu wa 302AB uyenera kuyikidwa kumbuyo kwa chitsamba chokhazikika kuti chikhale cholimba komanso kuti chisasunthe kapena kumasuka.
Malo oikamo mabearing ndi mafuta: chipolopolo chilichonse choikamo mabearing chili ndi malo oikamo mabearing, omwe ayenera kumangiriridwa mu malo oikamo mabearing pa silinda. Nthawi yomweyo, onetsetsani kuti dzenje lolowera mafuta mu bearing likugwirizana ndi malo oikamo mafuta mu silinda kuti mukhazikitse dongosolo loikamo mabearing.
Kukhazikitsa chivundikiro cha bearing: Mukayika chivundikiro choyamba cha bearing, tembenuzani crankshaft kuti muwonetsetse kuti palibe chomata. Ikani chivundikiro cha bearing ndikuchilimbitsa molingana ndi zomwe zafotokozedwa. Izi zimachitika pa chivundikiro chilichonse cha bearing. Ngati chivundikiro cha bearing chamata, vuto likhoza kukhala mu chivundikiro cha bearing kapena mu gawo la bearing. Chotsani ndikuwona ngati pali ma burrs kapena kusakwanira bwino kwa mpando wa bearing.
Mwa kutsatira njira izi, mutha kuonetsetsa kuti matailosi a crankshaft ayikidwa bwino ndikupewa kulephera kwa makina chifukwa cha kuyika kosayenera.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
