Wopanga ma gearbox adanena kuti izi ndizofanana ndi kuunikira kunyumba, komwe kumakhala kokwera kwambiri poyambira. Komabe, pakugwiritsa ntchito bwino, mphamvu yapano idzakhala yokwera kuposa momwe idangoyambika, moteronso injiniyo. Kodi mfundo yochititsa zimenezi ndi yotani? Ndikofunikira kuti timvetsetse kuchokera pamalingaliro oyambira amotor ndi mfundo yozungulira ya mota: injini yolowetsa induction itayimitsidwa, kuchokera pamawonekedwe a electromagnetic, imakhala ngati chosinthira. Kuthamanga kwa stator komwe kumagwirizanitsidwa ndi magetsi kumakhala kofanana ndi koyilo yoyamba ya transformer, ndipo kutsekedwa kwa rotor kutsekedwa kuli kofanana ndi koyilo yachiwiri ya transformer yomwe yafupika; Palibe kugwirizana kwamagetsi pakati pa stator winding ndi rotor winding, kokha kugwirizanitsa maginito, ndipo maginito a maginito amapanga dera lotsekedwa kupyolera mu stator, mpweya wa mpweya, ndi rotor core. Panthawi yotseka, rotor siinayambike chifukwa cha inertia, ndipo mphamvu yozungulira maginito imadula kuzungulira kwa rotor pa liwiro lalikulu locheka - liwiro la synchronous, kotero kuti kuzungulira kwa rotor kungapangitse mwayi wapamwamba womwe ungathe kufika. Chifukwa chake, mphamvu yayikulu imayenda kudzera pa kondakitala wa rotor, ndipo pakali pano imapanga mphamvu ya maginito yomwe imatha kuthana ndi mphamvu yamagetsi ya stator, monga momwe maginito achiwiri amasinthira maginito amtundu wa transformer amatha kuthana ndi maginito oyambira.
Chinthu chinanso ndi nkhani za khalidwe pamene opanga amagwiritsa ntchito zipangizo. Opanga ena amasankha zipangizo zochepetsera kuti asunge ndalama ndi kuchepetsa mitengo pogwiritsa ntchito zotsika. Zikatere, ngakhale wogwiritsa ntchitoyo akuyenda bwino, ndizosavuta kumva kumenyetsa mano. Nthawi zambiri, bokosi lomwe limagwiritsidwa ntchito ndi HT250 yachitsulo champhamvu kwambiri, pomwe zida zamagiya zimapangidwa ndi chitsulo chapamwamba kwambiri cha 20CrMo alloy ndipo adalandirapo chithandizo chamankhwala angapo. Kulimba kwapamwamba kwa kiyi yathyathyathya pa shaft yochepetsera kumafika HRC50. Chifukwa chake posankha chotsitsa magiya, ndikofunikira kumvetsetsa bwino zochepetsera zida osati kungosamala za mtengo.
Pali zinthu ziwiri zotheka kwa wosuta uyu, imodzi ndi vuto lawo. Pogwiritsa ntchito makina ochepetsera, akapitilira kuchuluka kwa makinawo, pangakhale zinthu zomwe makinawo sangathe kupirira ntchito yolemetsa. Chifukwa chake, pogulitsa chochepetsera, timakumbutsanso makasitomala kuti asamagwire ntchito pansi pa katundu wochepa, zomwe zingapangitse kuti magiya ofananirako kapena magiya a nyongolotsi asathe kupirira nthawi yonse yogwira ntchito, zomwe zimapangitsa kuti izi zitheke - kung'ambika kwa dzino kapena kuchuluka kwa mavalidwe.
