Zida zamkatindi mtundu wa zida zomwe mano amadulidwa mkati mwa cylinder kapena cone, mosiyana ndi zida zakunja zomwe mano ali kunja. Amalumikizana ndi magiya akunja, ndipo kapangidwe kake kamawathandiza kufalitsa kuyenda ndi mphamvu m'makina osiyanasiyana.

Pali ntchito zingapo zamagiya amkati:

1. Planetary Gear Systems: Magiya amkati amagwiritsidwa ntchito kwambiri pamakina a pulaneti, pomwe amalumikizana ndi zida za dzuwa ndi magiya a pulaneti. Dongosololi limalola kuti masitima apamtunda ang'onoang'ono komanso osunthika, omwe amagwiritsidwa ntchito nthawi zambiri pamagalimoto ndi makina akumafakitale.
2. Kutumiza Mphamvu: Magiya amkati amatha kugwiritsidwa ntchito kutumizira mphamvu pakati pa ma shafts ofanana kapena odutsana. Amagwiritsidwa ntchito nthawi zambiri pomwe zovuta za malo kapena zofunikira za torque zimafunikira kuti azigwiritsa ntchito.
3. Kuchepetsa Liwiro kapena Kuwonjeza: Zida zamkatiangagwiritsidwe ntchito kuonjezera kapena kuchepetsa liwiro rotational kutengera kasinthidwe awo ndi meshing ndi magiya kunja.
4. Kuwongolera Motion: Mu ma robotic ndi ma automation, magiya amkati amagwiritsidwa ntchito powongolera kuyenda bwino, kuwonetsetsa kuyenda kosalala komanso kolondola kwa manja a robotic, makina a CNC, ndi makina ena ongochita.
5. Njira Zosiyanitsira: Magiya amkati amathanso kupezeka m'makina osiyanasiyana, monga omwe amagwiritsidwa ntchito pamagalimoto oyendetsa magalimoto, kugawa mphamvu ndi torque pakati pa magudumu ndikuwalola kuti azizungulira pa liwiro losiyana.
6. In robotics ndi automation, magiya amkati amagwiritsidwa ntchito kwambiri kuti akwaniritse kusuntha kolondola mkati mwa malo ochepa. Mwachitsanzo, zida za roboti nthawi zambiri zimagwiritsa ntchito magiya amkati m'ma actuators awo kuti azitha kuyika bwino ndikubwerera pang'ono, zomwe zimapangitsa kuyenda kosavuta komanso kolamulirika. Kuphatikizika kwa magiya amkati kumathandiza mainjiniya kuphatikiza zida zovuta zamagiya m'magulu ang'onoang'ono, kulola maloboti kukhala olimba mtima komanso ochita bwino popanda kuwononga mphamvu kapena kuwongolera.
7. Zida zamkati nawonso otchuka kusankha mumagalimoto amagetsi (EVs), makamaka m'ma gearbox opangidwa kuti azigwira ntchito yothamanga kwambiri. Ma EV motors nthawi zambiri amagwira ntchito mothamanga kwambiri kuposa ma injini oyatsira mkati, kotero magiya amkati, ophatikizidwa ndi makina amagetsi a pulaneti, ndiofunikira kuti muchepetse liwiro ndikukulitsa torque. Kukonzekera uku kumawonjezera mphamvu zamagetsi, zomwe zimapangitsa kuti magetsi azikhala bwino komanso moyo wautali wa batri.
8. In makina osindikizirandimakina opanga nsalu, kumene kulondola kwakukulu kuli kofunika kwambiri, zida zamkati zimagwiritsidwa ntchito m'makina omwe amafunikira kusunga kasinthasintha kofanana ndi liwiro. Kukonzekera kwa zida zamkati kumathandizira kukhazikika komanso kulondola koyenda, kumathandizira kuti chinthu chomaliza chikhale chamtengo wapatali, kaya ndi zinthu zosindikizidwa kapena nsalu. Mawonekedwe awo ophatikizika komanso kuthekera kogawana katundu kumathandiza makinawa kuti azigwira ntchito mwachangu popanda kuyika pachiwopsezo cholakwika kapena kuvala mopitilira muyeso.

   Kuonjezera apo,zida zamankhwalamonga maloboti opangira opaleshoni ndi makina ojambulira nthawi zambiri amagwiritsa ntchito magiya amkati m'ma actuators awo kuti aziyenda molongosoka m'mipata yolumikizana. Magiya amkati amathandizira kukhala olondola komanso okhazikika, omwe ndi ofunikira pakugwira ntchito movutikira, kuzindikira, komanso chitetezo cha odwala.

Mapangidwe ndi kupanga zida zamkati zimakhala zovuta kwambiri kuposa zida zakunja chifukwa chazovuta zolowera mkati mwa zida panthawi yopangira. Komabe, amapereka zabwino pazinthu zina, monga kuphatikizika, kuchuluka kwa ma torque, komanso kugwira ntchito bwino.
