Kodi msonkhano wonyamula ma crankshaft wamagalimoto ndi chiyani?
Cholumikizira cha crankshaft cha magalimoto ndi gawo lomwe limayikidwa pa bulaketi yokhazikika ya crankshaft ndi silinda block ya injini yamagalimoto, makamaka yogwira ntchito yonyamula ndi kudzola mafuta. Nthawi zambiri imakhala ndi mitundu iwiri: zipolopolo za bearing ndi zipolopolo za flanged bearing. Zipolopolo za flanged bearing sizimangothandizira ndi kudzola mafuta a crankshaft, komanso zimayika crankshaft mozungulira, zomwe zimapangitsa kuti kapangidwe ka injini kakhale kokhazikika kwambiri .
Ntchito ya msonkhano wonyamula crankshaft
Youdaoplaceholder0 Thandizo ndi mafuta odzola : Chogwirira cha crankshaft, kudzera mu kapangidwe kake kapadera, chingathandize bwino crankshaft ndikuonetsetsa kuti ili yokhazikika komanso yolimba panthawi yogwira ntchito mwachangu. Pakadali pano, mafuta odzola amapanga filimu yamafuta pakati pa crankshaft ndi bearing bush, kuchepetsa kukangana ndi kuwonongeka.
Youdaoplaceholder0 Kuchepetsa kukangana ndi kutayika : Chogwirira cha crankshaft chimachepetsa kutayika kwa mphamvu mwa kuchepetsa kukangana mwachindunji pakati pa crankshaft ndi silinda block, motero kumawonjezera magwiridwe antchito ndi moyo wa injini.
Malo ndi kukhazikika kwa Youdaoplaceholder0: Chitsamba chozungulira sichimangothandiza crankshaft komanso chimayiyika motsatira njira ya axial, kuonetsetsa kuti crankshaft ikuyenda bwino komanso molondola.
Zipangizo ndi njira zopangira ma crankshaft bearing assemblies
Zipangizo zolumikizira ma crankshaft nthawi zambiri zimapangidwa ndi zitsulo. Zipangizo zodziwika bwino ndi izi:
Youdaoplaceholder0 copper alloy : Ili ndi mphamvu yabwino kwambiri yolimbana ndi kutopa, kutentha kwambiri komanso kukana kutopa.
Youdaoplaceholder0 aluminiyamu alloy : Ili ndi kapangidwe kopepuka komanso kukana dzimbiri bwino, zomwe zimapangitsa kuti ikhale yoyenera injini zogwira ntchito bwino komanso zopepuka.
Youdaoplaceholder0 iron alloy : Ili ndi mphamvu zambiri komanso yolimba, ndipo ndi yoyenera kugwiritsidwa ntchito pazochitika zinazake.
Chitsulo cha Youdaoplaceholder0 : chimagwiritsidwa ntchito mu injini zogwira ntchito kwambiri kuti zikwaniritse zofunikira zapamwamba komanso kulimba .
Ntchito yaikulu ya chogwirira cha crankshaft yamagalimoto ndikuthandizira ndikukonza crankshaft, kuonetsetsa kuti crankshaft siiwonongeka panthawi yogwira ntchito mwachangu. Zipolopolo za crankshaft zimapanga filimu yamafuta pakati pa crankshaft ndi zipolopolo za bearing, zomwe zimaletsa kukhudzana mwachindunji pakati pa ziwirizi, potero zimachepetsa kukangana ndi kuwonongeka ndikuwonjezera moyo wa crankshaft .
Kuphatikiza apo, ma crankshaft bearing ali ndi ntchito zotsatirazi:
Youdaoplaceholder0 Chepetsani kukangana ndi kuwonongeka : Filimu yamafuta pakati pa bearing ya crankshaft ndi crankshaft imatha kuchepetsa kukangana, motero imakulitsa moyo wa ntchito ya crankshaft. Ngati filimu yamafuta yasweka, kukhudzana mwachindunji pakati pa bearing bush ndi crankshaft kungayambitse kuwonongeka kwakukulu ndi kutentha kwa bearing .
Youdaoplaceholder0 Chepetsani phokoso : Chifukwa cha malo akuluakulu olumikizirana pakati pa chitsamba chonyamula katundu ndi crankshaft, kuthamanga kwapakati kumakhala kwakukulu, ndipo mphamvu ya mafuta odzola imapangitsa kuti ntchitoyo ikhale yosalala komanso phokoso likhale lotsika .
Youdaoplaceholder0 imapereka madigiri a axial of freedom : injini ikagwira ntchito, crankshaft imakula chifukwa cha kutentha ndikupanga kusuntha kwina ku mbali ya axial. Zipolopolo za bearing zimalola kusunthaku, pomwe ma bearing a mpira angayambitse kuwonongeka kosagwirizana komanso kuwonongeka msanga .
Youdaoplaceholder0 Kutaya kutentha mwachangu : Malo olumikizirana pakati pa chitsamba cholumikizira ndi crankjournal ndi akulu, ndipo mafuta a injini amazungulira nthawi zonse kuti azitha kudzola, zomwe zimatha kuchotsa kutentha kochulukirapo mwachangu ndipo ndizothandiza pakutaya kutentha kwa injini .
Ntchito zimenezi za crankshaft bearing zimaonetsetsa kuti injini ikugwira ntchito bwino komanso kuti izikhala yodalirika kwa nthawi yayitali.
Zifukwa zazikulu zomwe zimayambitsa zolakwika mu msonkhano wa crankshaft wa magalimoto ndi izi:
Youdaoplaceholder0 Mafuta odzola osakwanira kapena owonongeka: Mafuta odzola osakwanira kapena owonongeka, pampu yamafuta yowonongeka, chitoliro chamafuta chosweka, ndi zina zotero zonse zingayambitse kuchepa kwa kuthamanga kwa mafuta, zomwe zimapangitsa kuti mafuta asamayende bwino, kukangana kwambiri kwapafupi, ndikuwononga crankshaft bearing .
Youdaoplaceholder0 Kupanda kuyenerera koyenera : Ngati kuyenerera pakati pa shaft ndi bearing bush kuli kochepa kwambiri kapena kwakukulu kwambiri, kudzakhudza mphamvu ya mafuta, kuwonjezera kukangana, motero kuwononga bearing ya crankshaft .
Youdaoplaceholder0 Kulowerera monyanyira : Zinthu zonyamulira monga fumbi ndi zitsulo zimalowa m'malo opangidwa ndi zitsulo zomwe zili m'chipinda chosungiramo zinthu, zomwe zimapangitsa kuti pakhale mikwingwirima ndi kuwonongeka kosazolowereka.
Kugwiritsa ntchito molakwika kwa : monga kuyamba kozizira pa kutentha kochepa, kusakhala ndi nthawi yayitali, ndi kuzimitsa injini mwachindunji pambuyo pa kugwira ntchito yolemera kwa nthawi yayitali, ndi zina zotero, zonsezi zitha kuwononga crankshaft bearing .
Nkhani ya Youdaoplaceholder0 Assembly : Kusankha molakwika zipolopolo zonyamula katundu zomwe sizikugwirizana ndi galimoto yoyambirira kungayambitsenso kuwonongeka kwa zipolopolo za crankshaft .
Njira zopewera ndi zochiritsira za Youdaoplaceholder0 zikuphatikizapo:
Youdaoplaceholder0 Nthawi zonse onani kuchuluka kwa mafuta opaka: Onetsetsani kuti mafuta opaka ndi okwanira komanso abwino, ndipo musinthe nthawi zonse kuti mupewe kugwiritsa ntchito mafuta opaka otsika.
Youdaoplaceholder0 Sinthani malo olowera : Onetsetsani kuti malo olowera pakati pa shaft ndi bearing bush ali mkati mwa malo oyenera (nthawi zambiri 0.08-0.10mm).
Youdaoplaceholder0 Kuyambitsa ndi kugwiritsa ntchito koyenera : Mukayamba m'nyengo yozizira, choyamba tembenuzani crankshaft kangapo. Mukayamba, isiyeni igwire ntchito mpaka kutentha kwa madzi kukwere pamwamba pa 40°C musanayendetse .
Youdaoplaceholder0 Pewani kungokhala chete kwa nthawi yayitali ndikuzimitsa injini nthawi yomweyo mutagwira ntchito yolemera kwambiri : Injini ikagwira ntchito yolemera kwa nthawi yayitali, iyenera kuloledwa kuti igwire ntchito kwakanthawi isanazimitsidwe .
Youdaoplaceholder0 Gwiritsani ntchito mafuta opaka mafuta abwino kwambiri: Sankhani mafuta opaka mafuta abwino kwambiri, yang'anani ubwino wake nthawi zonse, ndikuyika mafuta opaka mafuta owonongeka nthawi yomweyo.
Kudzera mu miyeso yomwe ili pamwambapa, zolakwika mu msonkhano wa magalimoto onyamula crankshaft zitha kupewedwa ndikuthetsedwa bwino, kuonetsetsa kuti injini ikugwira ntchito bwino komanso kukulitsa moyo wake wautumiki.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
Malingaliro a kampani Zhuo Meng Shanghai Auto Co., Ltd. yadzipereka kugulitsa MG&MAXUSzida zamagalimoto zalandiridwa kugula.
