Mafunso Ofunsidwa Kawirikawiri

Zolakwika za ma mota a asynchronous a magawo atatu nthawi zambiri zimatha kugawidwa m'magawo awiri: zolakwika zamagetsi ndi zolakwika zamakina.
Zolakwika za makina ndi monga: mabearing osakula bwino kapena owonongeka, manja a mabearing, zipewa zamafuta, zipewa zomaliza, mafani, mipando ndi zina, komanso kuwonongeka kwa zigawo za shaft. Zolakwika zamagetsi zimaphatikizapo: kusweka kwa stator ndi rotor winding, pakati pa ma turn (gawo), kupita pansi, ndi zina zotero.

Stator ndi rotor zimapangidwa ndi mapepala achitsulo a silikoni omwe amateteza mbali zonse ziwiri ndipo ndi gawo la dera la maginito la mota. Kuwonongeka ndi kusinthika kwa stator ndi rotor cores kumachitika makamaka chifukwa cha zinthu zotsatirazi.
(1) Kuwonongeka kwakukulu kwa ma bearing kapena kusakhazikika bwino, zomwe zimapangitsa kuti stator ndi rotor zisakanike, zomwe zimapangitsa kuti pamwamba pa chitsulo cha silicon pawonongeke, zomwe zimapangitsa kuti chitsulo chichepe pakati pa zitsulo za silicon, zomwe zimapangitsa kuti injini itayike kwambiri, zomwe zimapangitsa kuti kutentha kwa injini kukwere kwambiri, pamene mukugwiritsa ntchito fayilo yopyapyala ndi zida zina kuchotsa burr, kuchotsa kulumikizana kochepa kwa zitsulo za silicon, kuyeretsa kenako nkupaka utoto woteteza, ndikutenthetsa ndi kuumitsa.
(2) Pamwamba pa chitsulo chachita dzimbiri chifukwa cha chinyezi ndi zifukwa zina, chiyenera kupukutidwa ndi sandpaper, kutsukidwa ndi kupakidwa utoto woteteza.
(3) Pakati pa mano kapena pakamwa pawo payaka chifukwa cha kutentha kwambiri komwe kumachitika chifukwa chothira pansi. Chida monga chisel kapena scraper chingagwiritsidwe ntchito kuchotsa zinthu zosungunuka ndikuziumitsa ndi utoto woteteza kutentha.
(4) Kuphatikiza pakati pa pakati ndi maziko a makina ndi kotayirira, ndipo zomangira zoyambirira zitha kumangidwa. Ngati zomangira zomangira zalephera, bowolaninso mabowo omangira ndikugogoda pa maziko a makina, mangani zomangira zomangira.

Ngati chogwirira chozungulira chilibe mafuta, phokoso la mafupa lidzamveka. Ngati phokoso losalekeza lamveka, likhoza kukhala kusweka kwa mphete yachitsulo yonyamula. Ngati chogwiriracho chasakanikirana ndi mchenga ndi zinyalala zina kapena zigawo za chogwiriracho zili ndi kuwonongeka pang'ono, zipanga phokoso pang'ono. Yang'anani mutachotsa: choyamba yang'anani thupi lozungulira la chogwiriracho, mkati ndi kunja kwa mphete yachitsulo kuti muwone ngati chawonongeka, dzimbiri, zipsera, ndi zina zotero. Kenako pindani mphete yamkati ya chogwiriracho ndi dzanja lanu ndikupanga mulingo wonyamula, kankhirani mphete yakunja yachitsulo ndi dzanja lanu lina, ngati chogwiriracho chili bwino, mphete yakunja yachitsulo iyenera kuzungulira bwino, palibe kugwedezeka ndi kugwedezeka koonekera pozungulira, palibe kubwerera kwa mphete yakunja yachitsulo mutayima, apo ayi chogwiriracho sichingagwiritsidwenso ntchito. Dzanja lamanzere litalowa mu mphete yakunja, dzanja lamanja limakanikiza mphete yamkati yachitsulo, kukakamiza kukankhira mbali zonse, ngati mukumva kumasuka kwambiri mukakankhira, ndi kuwonongeka kwakukulu.

Kukonza zolakwika pamwamba pa bereji kungathe kuchotsedwa ndi pepala losanjikiza, kenako nkulowa mu kuyeretsa mafuta; ming'alu ya bereji, mkati ndi kunja kwa mphete yosweka kapena yonyamula kwambiri, iyenera kusinthidwa ndi mabearing atsopano. Mukasintha bereji yatsopano, gwiritsani ntchito mtundu womwewo wa bereji monga woyambirira. Kuyeretsa ndi kuwonjezera mafuta pa bereji.

Njira yoyeretsera maberiya: choyamba pukutani mafuta otayira pamwamba pa mpira wachitsulo; pukutani mafuta otsala ndi nsalu ya thonje; kenako ziviikani beriya mu petulo ndikutsuka mpira wachitsulo ndi burashi; kenako tsukani beriya mu petulo woyera; potsiriza ikani beriya papepala kuti petuloyo iume ndi kuuma.

Njira yopaka mafuta pa bere: Posankha mafuta ozungulira, chinthu chofunika kwambiri ndi momwe bere limagwirira ntchito, monga kugwiritsa ntchito malo (onyowa kapena ouma), kutentha kwa ntchito ndi liwiro la injini. Mphamvu ya mafuta siyenera kupitirira 2/3 ya voliyumu ya chipinda chonyamula mafuta.
Mukawonjezera mafuta odzola ku bearing, mafutawo ayenera kufinyidwa kuchokera mbali imodzi ya bearing kenako mafuta ochulukirapo ayenera kuchotsedwa pang'onopang'ono ndi chala, bola mafutawo atha kuwonjezeredwa mpaka atatseka mpira wachitsulo bwino. Mukawonjezera mafuta odzola ku bearing cover, musawonjezere kwambiri, pafupifupi 60-70% ndi okwanira.

(1) kupindika kwa shaft ngati kupindika sikuli kwakukulu, kungakonzedwe pogaya m'mimba mwake wa shaft, njira yozembera mphete; ngati kupindika kuli kopitilira 0.2mm, shaft ikhoza kuyikidwa pansi pa makina osindikizira, pokonza kuthamanga kwa kupindika kwa shot, ndikukonza pamwamba pa shaft ndi lathe cutting grinding; monga kupindika kuli kwakukulu kwambiri kuyenera kusinthidwa ndi shaft yatsopano.
(2) Kuwonongeka kwa khosi la shaft khosi si lalikulu kwambiri, likhoza kukhala pakhosi la chromium plating, kenako likupera mpaka kukula kofunikira; likhoza kukhala pakhosi la welding overlay, kenako limatha kukhala pa lathe cutting ndi grinding; ngati kuvala kwa journal kuli kwakukulu kwambiri, komanso mu journal ya 2-3mm, kenako tembenuzani sleeve pamene kutentha kuli mu journal, kenako kutembenukira ku kukula kofunikira.
Kuzama kwa ming'alu ya shaft kapena ming'alu yopingasa ya shaft sikupitirira 10%-15% ya m'mimba mwake wa shaft, ming'alu yayitali siyipitirira 10% ya kutalika kwa shaft, ikhoza kukonzedwa pogwiritsa ntchito njira yolumikizira pamwamba, kenako kutembenuzira bwino kukula kofunikira. Ngati ming'alu yomwe ili mu shaft ndi yayikulu kwambiri, shaft yatsopano ikufunika.

Ngati pali ming'alu m'nyumba ndi chivundikiro chakumapeto, ziyenera kukonzedwa pogwiritsa ntchito welding overlay. Ngati malo otseguka a bearing bore ndi akulu kwambiri, zomwe zimapangitsa kuti bearing end cover ikhale yomasuka kwambiri, khoma la bearing bore likhoza kuphwanyidwa mofanana pogwiritsa ntchito punch, kenako bearing ikhoza kuyikidwa mu chivundikiro chakumapeto, ndipo pa ma mota omwe ali ndi mphamvu yayikulu, kukula kofunikira kwa bearing kumathanso kupangidwa ndi makina poika mkati kapena kuyika ma plating.

Malo oyika injini sali ofanana. Limbitsani maziko a injiniyo ndipo muyikonze bwino mukamaliza kulinganiza maziko.
Zipangizozi sizili zozungulira ndi kulumikizana kwa injini. Konzaninso zozungulirazo.
Rotor ya mota siili bwino. Kulinganiza kwa rotor mosasunthika kapena mosinthasintha.
Pulley ya lamba kapena cholumikizira sichili bwino. Kulinganiza kwa Pulley kapena cholumikizira.
Mutu wa shaft yozungulira kapena yopingasa. Wongolani shaft yozungulira, ikani shaft yowongoka kenako ikani seti kuti ibwererenso.

Kulumikizana kolakwika kwa stator winding, short circuit kapena grounding, zomwe zimapangitsa kuti magetsi a magawo atatu asayende bwino komanso kuyambitsa phokoso.
Zinthu zakunja kapena kusowa kwa mafuta opaka mkati mwa bearing. Tsukani ma bearing ndipo musinthe ndi mafuta atsopano pa 1/2-1/3 ya bearing chamber.
Kusuntha kosalekeza pakati pa stator ndi nyumba kapena rotor core ndi rotor shaft. Yang'anani momwe zimakhalira, kulumikizanso, ndi kukonza.
Kupukuta molakwika kwa stator ndi rotor. Pezani malo okwera a chitsulo, kukonza kugaya.
Phokoso la maginito amagetsi panthawi yogwira ntchito ya injini. N'kovuta kuthetsa pokonza.

① kukhuthala kochepa, kuchuluka kwa zinthu zolimba komanso kusavuta kumizidwa.
② imachira mwachangu, imalumikizana mwamphamvu komanso imasinthasintha.
③Makhalidwe amphamvu amagetsi, kukana kutentha, kukana chinyezi komanso kukhazikika kwa mankhwala.

a) Mpata wa shaft ndi matailosi ndi wochepa kwambiri.
b) Kutsegula kwa chikhodzodzo cha mafuta pang'ono komanso kusakwanira kwa chakudya chamafuta.
c) kutentha kwakukulu kwa mafuta odzola.
d) Kuvulala kwa kafukufuku wa matailosi a shaft.
e) mafuta osabwerera bwino komanso mafuta osakwanira.
