Mfundo yaikulu ya ntchito yaMicro Reduction gear motorndikuchepetsa liwiro ndikuwonjezera torque kudzera pakutumiza zida. paMa Micro Reduction Motorsgwiritsani ntchito kutumiza kwa ma giya awiri pamlingo uliwonse kuti mukwaniritse cholinga chochepetsa liwiro. Mwachitsanzo, giya yaing'ono yoyendetsa giya yayikulu imatha kukwaniritsa zotsatira zina zochepetsera. Kupyolera mu dongosolo la masitepe ambiri, liwiro likhoza kuchepetsedwa kwambiri. Mfundo yogwirira ntchito iyi imalola ma motors ochepetsera ang'onoang'ono kuti atenge gawo lofunikira pamapulogalamu omwe amafunikira liwiro lotsika komanso torque yayikulu.
Kugwiritsa ntchito magiya muma micro gear motorszimawonekera makamaka m'mapangidwe awo ndi ntchito. paMicro gear kuchepetsa injinindi ayoyendetsedwa ndi ma micro motorchipangizo chotsekedwa chochepetsera kufala, chomwe nthawi zambiri chimasonkhanitsidwa ndikuperekedwa ndi katswiri wopanga magalimoto ochepetsa. Kuphatikizika kumeneku sikungangochepetsa liwiro ndikuwonjezera torque, komanso kumakhala ndi mawonekedwe ochepetsa mphamvu zamagetsi, magwiridwe antchito apamwamba, kugwedezeka pang'ono komanso phokoso lochepa. Mfundo yamapangidwe a makina ochepetsera giya imaphatikizapo kuphatikiza zida za dzuwa ndi zida za pulaneti, zomwe zimakwaniritsa kuchepetsedwa kwakukulu kudzera mumayendedwe amagetsi amitundu yambiri kuti akwaniritse zosowa zamakina osiyanasiyana.
Magawo ogwiritsira ntchito ma microreduction motors ndi otakata kwambiri. Amagwiritsidwa ntchito makamaka pamakina ang'onoang'ono opanga mafakitale, zida zamagetsi, zida zapanyumba ndi zina. Mwachitsanzo, m'mafakitale opepuka m'mafakitale onyamula, chakudya, nsalu ndi zodzoladzola,makina opangidwa ndi micro-gearedzitha kuwongolera magwiridwe antchito. Pazida zamagetsi, makamaka mizere yopangira,ma micro gear motorsamatenga gawo lofunikira posintha liwiro lawo malinga ndi zosowa za ogwiritsa ntchito. Kuphatikiza apo, pazida zamagetsi zapanyumba monga makina a soyamilk, juicers, firiji, ndi makina ochapira, ma micro Reduction motors amapereka magwiridwe antchito komanso magwiridwe antchito.
Kupanga ndi kuyeza pakupanga kwa Micro MIM
Gearwheel ndi gawo lomwe lili mkati mwa chipangizo chotumizira chomwe chimatumiza mphamvu yozungulira kupita ku giya ina kapena chipangizo china komanso ndi chinthu chomwe chimapangidwa pamakina olondola kwambiri. M'zaka zaposachedwa njira zopangira zida zazing'ono komanso magiya ang'onoang'ono opangidwa ndi zitsulo ndi zida zadothi zapamwamba zapangidwa [1].Magalimoto a Microplanetaryapangidwanso kuchokera ku nickel-ferrous (Ni-Fe) ndi magalasi achitsulo opangidwa ndi nickel opangidwa ndi X-ray lithography & electro-deposition (direct-LIG) [2] ndi jekeseni woumba [3], motsatira. /
Komabe, pakufunika magiya ang'onoang'ono opangidwa ndi zida zolimba zomwe zimagwiritsidwa ntchito nthawi zonse kuti zichepetse komanso kudalirika kwazinthu zosiyanasiyana. M'mawu opangira zinthu cholinga chake ndikukwaniritsa chuma chambiri kuti chikwaniritse zosowa zamakampani. Micro metal ufa jakisoni akamaumba (μ MIM) ndi zothandiza popanga yaying'ono kakulidwe ndi microstructured mbali [4-5], koma kuyeza kulondola kwa magiya ang'onoang'ono opangidwa ndi μ MIM kwakhala kovuta. /
A zida za microplanetaryzopangidwa ndi 17-4PH zitsulo zosapanga dzimbiri zinapangidwa ndi μ MIM monga gawo la polojekiti ya Osaka. Ubwino wa ma giya a pulaneti ophatikizana kwambiri adawunikidwa poyesa kusiyanasiyana kwa mano agiya ndi kusanthula kwazithunzi za digito. Thezida za microplanetarywopangidwa ndi mitundu itatu ya ma gearwheel opangidwa ndi μ MIM ndondomeko ikuwonetsedwa mu Chithunzi1. Mu phunziro ili, kulondola kwa zida za pulaneti ndi miyeso yomwe ikuwonetsedwa mu Chithunzi 1 (c) idawunikidwa. Mafotokozedwe a zida zapadziko (monga sintered) akuwonetsedwa mu Gulu 1. /

Table 1. Mafotokozedwe a mapulaneti (monga sintered) . Zida zomwe zimagwiritsidwa ntchito popanga zida zowonongeka kwambiri zinali zitsulo zosapanga dzimbiri 17-4PH madzi-atomized ufa (D50 = 2μm) ndi poly-acetyl based binders. Kutsegula kwa ufa wa feedstock kunali 60vol%. Chakudyacho chinapangidwa ndi jekeseni pogwiritsa ntchito makina opangira jakisoni othamanga kwambiri (FANUC Ltd., S-2000i 50A). Zomera zobiriwirazo zidamangidwa pa 600ºC kwa maola awiri mumlengalenga wa nayitrogeni, ndikuwotchedwa pa 1150ºC kwa maola awiri pansi pa argon. Magawo osokera adawumitsidwanso zaka 480ºC kwa ola limodzi. /
Kulondola kwa magiya odziwika bwino nthawi zambiri amawunikidwa ndi mayeso a master gear meshing kapena kulumikizana ndi profilometry. Komabe, pankhani ya ma giya ophatikizika ndizovuta kupanga zida zapamwamba ndikuyesa mawonekedwe polumikizana. Chifukwa chake njira yoyezera mawonekedwe osalumikizana ndi zida zapamwamba monga zowonera za laser displacement ndi kusanthula kwazithunzi za digito zimawonedwa kuti ndizothandiza pakuwunika kulondola kwa magiya a ultracompact. /
