Bearing system ndi gawo lofunikira la mota, ndiye chinthu chofunikira kwambiri pamakina agalimoto omwe ali ndi zida zofunika kwambiri, kuti akonze molingana ndi injiniyo.njira yoberekera, choyamba ayenera kumvetsetsa nkhani zotsatirazi.
1, Kunyamula kutsogolo ndi kumbuyo kwa injini
Kumbali yakutsogolo kwa injini kumatanthawuza kunyamula pafupi ndi mbali yonyamula makina, yomwe imatchedwanso kunyamula katundu kapena axial end bear; ndikumbuyo kuberekaamatanthauza kunyamula pafupi ndi kuzizira kwa fan fan, komwe kumatchedwanso kuti fan side bearing kapena non-axial end bear.
2, Kupeza mapeto ndi mapeto aulere a injini
Kupeza malekezero ndi malekezero aulere ndi mawu achindunji pamapangidwe amagetsi onyamula magalimoto. Pa ntchito ya galimoto, chifukwa cha zinthu zosiyanasiyana monga kukulitsa matenthedwe ndi chidule cha zigawo zikuluzikulu, mphamvu maginito pakati pa stator ndi rotor, etc., osiyanasiyana axial kayendedwe zidzachitika pakati pa stator ndi rotor. Kuti mukwaniritse kusintha kwa axial dimensional ndi zovuta zakusamuka zomwe zimachitika m'zigawozo, malo ena a axial ayenera kusiyidwa pamapangidwe ndi kupanga ma mota. Pachifukwa ichi, pokonza kayendedwe ka galimotoyo, mphete yakunja yazitsulo idzakhazikika mwamphamvu pamapeto amodzi, mwachitsanzo, kusamutsidwa kwa axial kumapeto kumeneku sikudzaloledwa kuchitika, ndipo mapeto awa adzakhala. kutchedwa mapeto opeza kapena mapeto okhazikika; ndi dongosolo lonyamula pa mapeto ena a galimoto adzasiya kuchuluka kwa axial chilolezo kuti agwirizane ndi mphete yakunja yonyamula kudzera axial zoyenera miyeso ya mkati ndi kunja kubala zisoti ndi chipewa mapeto, pofuna kuonetsetsa kuti gawo la rotor limakhala ndi gawo lofunikira la axial poyendetsa galimoto, popeza Mapeto ali ndi kuyenda kwa axial, motero mapeto ake amatchedwa mapeto aulere kapena mapeto oyandama.
3, mayendedwe ozama a mpira ndi ma cylindrical roller bearings
Mipira yozama ya groove imatha kuchepetsa kusuntha kwa mbali ziwiri za shaft, kulondola kwambiri, kutsika kwapakati pa kukangana, ndiye chisankho chabwino chakumapeto kwa galimoto, mpira ndi manja onyamula kuti agwirizane ndi mzere, ndiko kuti, njira yoyendetsera galimoto. njira yolumikizirana ya mphete yozungulira, yolumikizirana ndi yaying'ono, mphamvu yonyamula ma radial si yayikulu, siyenera kupirira katundu wolemetsa ndi katundu wolemetsa; ndi ma cylindrical wodzigudubuza mayendedwe alibe axial choletsa odzigudubuza, kuchita mfulu mapeto a thandizo kuti ntchito, akhoza Agwirizane ndi kukulitsa matenthedwe kapena unsembe cholakwika chifukwa cha kutsinde ndi chipolopolo wachibale udindo kusintha, wodzigudubuza ndi raceway ndi mzere kukhudzana, kunyamula kuthamanga. njanji ndi mphete zozungulira, kukhudzana pamwamba ndi yaikulu, ma radial katundu kunyamula mphamvu, oyenera kunyamula katundu wolemetsa ndi katundu mantha.
4, injini yonyamula malo kusankha kumapeto
Kuchokera pa ntchito yeniyeni ya galimoto ndi kukumana ndi zipangizo zofananira ndi kuganizira kutsata docking, malo mapeto a kusankha ambiri mu axial mapeto, ndi axial wachibale zofunika udindo si okhwima zikhalidwe, angathenso kusankhidwa mu sanali -mapeto axial, amakonda kunyamula zofunikira zamagalimoto; koma ngati zida zokokedwa pa motor axial runout zili ndi zofunikira zolimba, ndiye kuti kumapeto kwa ma axial akuyenera kusankhidwa kumapeto kwa axial. Poyika mapetokukhala ndi mphete yakunjandi chivundikiro chamkati ndi chakunja choyima chakufa, chokhala ndi chivundikiro chomangidwira ku mawondo kapena chivundikiro chakumapeto.
5, Kusankhidwa kwa mtundu wamtundu wamagalimoto
Pamene katundu wonyamulidwa ndi galimoto si waukulu, zitsulo zozama za mpira zimagwiritsidwa ntchito; ndipo mogwirizana ndi zofunikira za zinthu zenizeni ntchito, chifukwa katundu mantha, komanso katundu wokulirapo, mayendedwe cylindrical wodzigudubuza ayenera kugwiritsidwa ntchito mu axial mapeto a galimoto, poyerekeza ndi kukula yemweyo wa zitsulo zakuya poyambira mpira, cylindrical wodzigudubuza. mayendedwe otulutsa mphamvu amatha kuwonjezedwa ndi 1.5-3 nthawi, kulimba komanso kukana kugwedezeka kuli bwino. Mipira yakuya yakuya yokhala ndi mphamvu yozungulira kuposa ma cylindrical roller bearings yofooka, koma imatha kunyamula mphamvu zinazake za axial, pomwe ma cylindrical roller bearings sangathe kunyamula mphamvu ya axial. Poona zakuya poyambira mpira mayendedwe ndi cylindrical wodzigudubuza mayendedwe structural makhalidwe, chifukwa kufunika sintha mayendedwe cylindrical wodzigudubuza mayendedwe kwa galimoto, ayenera kukhazikitsidwa ntchito akafuna wosanganiza, ndiko kuti, payenera kukhala osachepera imodzi ya zitsulo zakuya poyambira mpira. ndi kugwiritsa ntchito kwake.
Mphamvu yamagetsi yamagetsi yamagetsi nthawi zambiri imakhala yayikulu, kuti ikwaniritse katundu wolemetsa komanso kuwongolera kochepa kwa axial runout, nthawi zambiri malinga ndi kasinthidwe koyenera kagawo katatu. Pofuna kupititsa patsogolo mphamvu yobereka ndi moyo wautumiki wa mapeto a axial kutambasuka, kumapeto kwa axial kutambasuka ndi seti ya zitsulo zodzigudubuza zozungulira ndi gulu la zitsulo zakuya zakuya za mpira, zitsulo za cylindrical zodzigudubuza zonyamula katundu wozungulira, ndi Mipira yozama yolowera kumalo opangira malo, kungonyamula katundu wa axial (ndipo motero mpira wakuya wokhala ndi mphete yakunja ndi ma radial onyamula manja nthawi zambiri umasiya chilolezo china); mbali ina ya galimotoyo molingana ndi kufunikira kwenikweni kusankha mayendedwe a mpira wakuya, ngati n'koyenera, mungathenso Mapeto ena a galimoto amatha kusankha mayendedwe a mpira wakuya malinga ndi zosowa zenizeni, ndi mayendedwe a cylindrical roller angakhalenso osankhidwa ngati kuli kofunikira.
Pofuna kupewa mayendedwe oyendetsa galimoto, mphete yakunja yokhala ndi mphete yonyamula, yokhala ndi mphete yamkati ndi shaft iyenera kusankha kulekerera koyenera; Kaya ndi mapeto a axial a chipangizo chonyamulira, kapena mapeto osakhala axial a chipangizo chonyamulira, ndi labyrinthine kapangidwe, ndi kusindikiza ndi mphete yosindikiza, osati kuteteza chipinda chonyamula mafuta kutayikira mkati mwa galimotoyo, kuwonongeka kwa kutchinjiriza koyilo, komanso kuteteza kunja kwa fumbi kapena madzi kulowa muchipinda chonyamulira, kuti mayendedwe azikhala oyera. Zimalepheretsanso fumbi lakunja kapena madzi kulowa m'chipinda choberekera ndikusunga ma berelo aukhondo.
Makina onyamula mafuta okwera kwambiri amayenera kukhala ndi mafuta odzaza ndi kukhetsa mapaipi kuti athandizire kusinthana ndi mafuta, ndipo amatha kuzindikira kuthira mafuta osayimitsa kapena kukhetsa.
