Amagiya angahlukaniswa ngokuma kwezinyo, ukuma kwegiya, ukuma komugqa wamazinyo, indawo lapho amazinyo egiya atholakala khona, kanye nendlela yokukhiqiza.
1) Amagiya angahlukaniswa abe ijika lephrofayili yezinyo, i-angle yokucindezela, ukuphakama kwezinyo kanye nokufuduka kuye ngokuma kwezinyo.
I-2) Amagiya ahlukaniswe amagiya angama-cylindrical, amagiya e-bevel, amagiya angewona ayisiyingi, ama-racks, namagiya worm-worm ngokuya ngokuma kwawo.
3) Amagiya ahlukaniswe amagiya e-spur, amagiya e-helical, amagiya e-herringbone, namagiya agobile ngokuya ngokuma komugqa wezinyo.
4) Ngokwegiya langaphezulu lapho amazinyo egiya atholakala khona, ihlukene ngegiya langaphandle kanye negiya langaphakathi.Umbuthano wethiphu wegiya langaphandle mkhulu kunomjikelezo wempande;kuyilapho isiyingi sethiphu segiya langaphakathi sincane kunomjikelezo wempande.
I-5) Ngokwendlela yokukhiqiza, amagiya ahlukaniswe ngamagiya okuphonswa, amagiya okusika, amagiya agingqayo, amagiya okudonsa, njll.
Ukudluliswa kwegiya kuhlukaniswe ngezinhlobo ezilandelayo:
1. I-cylindrical gear drive
2. I-Bevel gear drive
3. Igiya le-Hypoid
4. I-Helical gear drive
5. Ukushayela izikelemu
6. I-arc gear drive
7. I-Cycloidal gear drive
8. Ukudluliswa kwamagiya eplanethi (okuvame ukusetshenziswa ukudluliselwa kweplanethi okujwayelekile okuhlanganisa igiya lelanga, igiya leplanethi, igiya langaphakathi kanye nesithwali seplanethi)
