Kusankha kwa injini yochepetsera pang'ono [malangizo]

Zotsatirazi ndi momwe mungasankhire ma motors ochepetsa giya:

1. Dziwani zoyambira

Magawo oyambira amagalimoto akuphatikiza: voliyumu yovoteledwa, liwiro lovotera, torque yovotera, mphamvu yovotera, torque ndi kuchepetsa chiŵerengero cha gearbox.

2. Malo ogwirira ntchito zamagalimoto

Kodi injini ikugwira ntchito kwa nthawi yayitali kapena yayifupi? Nthawi zonyowa, zotseguka (chitetezo cha dzimbiri, chosalowa madzi, kalasi yotsekera, chivundikiro choteteza pamene M4), komanso kutentha kwagalimoto.

3. Njira yoyika

Njira zoyikamo magalimoto zimaphatikizapo: kuyika kopingasa ndi kuyika koyima. Kodi tsindelo limasankhidwa ngati tsinde lolimba kapena tsinde lopanda kanthu? Ngati ndikuyika shaft yolimba, kodi pali mphamvu za axial ndi mphamvu za radial? Kapangidwe ka kufala kwakunja, mawonekedwe a flange.

4. Chiwembu chadongosolo

Kodi pali chofunikira chilichonse chosagwirizana ndi njira yolowera, kolowera kwa bokosi la terminal, malo a nozzle, etc.

Mbali yayikulu ya injini yochepetsera giya yaying'ono ndikuti imakhala ndi ntchito yodzitsekera yokha. Ubwino wake ndi mawonekedwe ophatikizika, kulondola kwambiri, kusiyana kochepa kobwerera, kukula kochepa, torque yayikulu yotumizira komanso moyo wautali wautumiki. Galimotoyo idapangidwa ndikupangidwa pamaziko a ma module ophatikizira. Pali njira zambiri zophatikizira zamagalimoto ndi njira zoyikira, makonzedwe amapangidwe, ndipo chiŵerengero chotumizira chimasinthidwa bwino kuti chikwaniritse mikhalidwe yosiyanasiyana yogwirira ntchito ndikuzindikira ma mechatronics.

Mu injini yochepetsera ya micro DC, bokosi lochepetsera ndi lamitundu yosiyanasiyana, ndipo njira yopangira shaft imapangidwanso molingana ndi zosowa zosiyanasiyana. Zodziwika bwino ndi shaft yapakati, shaft yotuluka kumbuyo ndi shaft yapambali (90 °), komanso palinso mawonekedwe opangira ma shaft awiri. Gawo la giya lapakati pakuchepetsa mphamvu yamagetsi ndilocheperako, kotero kulondola kwake ndikwambiri kuposa njira zina zotulutsa, ndipo phokoso ndi kulemera kwake ndizochepa, koma kuchuluka kwake kumakhala kotsika (poyerekeza ndi mota yochepetsera, inde njira yotulutsira pakatikati ndiyokwanira), pomwe mphamvu yamagetsi yamagetsi yamagetsi yaying'ono ya DC idzakhala yokulirapo, chifukwa ili ndi magawo ambiri agiya, koma kulondola kumakhala kotsika ndipo phokoso likhala lokwera pang'ono.

Kawirikawiri, injini yochepetsera ya micro DC imagwiritsa ntchito mndandanda wa N, monga N10\N20\N30, ndi zina zotero (zitsanzo zonse zingagwiritsidwe ntchito ngati magalimoto ochepetsera, ndipo bokosi lochepetsera likhoza kuwonjezeredwa). Mphamvu yamagetsi imayendetsedwa kwambiri mkati mwa 12V kuti ikhale yabwino. Kukwera kwambiri kwamagetsi kungapangitseMicro DC kuchepetsa injiniphokoso ndi kufupikitsa moyo wake.

Pakadali pano, ma motors ambiri ochepetsa pamsika amagwiritsa ntchito ma gearbox 12 ochepetsera, ndipo ma mota ang'onoang'ono amagwiritsa ntchito maburashi wamba a N20 (moyo wautumiki wa maburashi a kaboni udzakhala wautali pang'ono), womwe utha kukhala ndi encoder mafoto kapena ma encoder wamba. Ma encoder a Photoelectric a N20 motors amagwiritsidwa ntchito kwambiri pazinthu zolondola kwambiri. Encoder imayankha ma siginecha 48 pomwe mota yaying'ono ya DC imazungulira bwalo limodzi. Poganiza kuti chiŵerengero chochepetsera ndi 50, shaft yotulutsa yochepetsera idzalandira zizindikiro za 2400 pamene izungulira bwalo limodzi. Zida zina zokha zomwe zimafunikira kuwongolera kopitilira muyeso ndizogwiritsa ntchito.

Zopangira kaboni burashi ndi mayendedwe a Micro DC kuchepetsa mota zikhudza moyo. Posankha mota yochepetsera, ngati mota wamba ya DC yomwe ili ndi brushed siyingakwaniritse zofunikira za moyo ndipo simukufuna kusintha mota yopukutidwa, mutha kusintha burashi wamba ndi burashi ya kaboni, m'malo mokhala ndi mafuta ndi mpira. , kapena onjezani ma giya modulus kuti muwonjezere moyo wautumiki wa mota ya Micro DC.

Nthawi zambiri pamakhala kusamvetsetsana pakusankha ma motors ang'onoang'ono a DC. Kakulidwe kakang'ono, kabwinoko, kokwezeka kokulirapo, kabwinoko, ndipo ena amafunikira kukhala chete. Izi sizimangowonjezera nthawi yosankhidwa ya micro motor, komanso kumawonjezera mtengo. Kwa kukula kwamakina a micro DC motor, ndikofunikira kuti musankhe molingana ndi malo oyikapo omwe mankhwalawa angavomereze (osati kukula kokhazikika, apo ayi ndikofunikira kutsegula nkhungu, zomwe zimawonjezera mtengo). Kwa torque yotulutsa, ingosankha yoyenera. Kukula kwa torque, magawo agiya ochulukirapo, ndipo mtengo wake udzawonjezeka kwambiri. Ponena za kufunikira kwa ma motors ochepetsa ma micro DC, ndizovuta kukwaniritsa. Njira yokhayo ndikuwongolera phokoso. Zomwe zimayambitsa phokoso zimaphatikizapo phokoso lamakono, phokoso lachisokonezo, ndi zina zotero. Kwa micro DC kuchepetsa injini, phokosoli likhoza kunyalanyazidwa.
