Iigiya ze-Spiral bevel zahlulwe zaba zintlobo ezimbini, enye yi-spiralizixhobo ze-bevel, ene-asi enkulu kunye ne-asi encinci ehlanganayo; enye yi-hypoid spiral bevel gear, kunye nomgama othile wokumisa phakathi kwe-asi enkulu kunye ne-asi encinci. Iigiya ze-Spiral bevel zisetyenziswa kakhulu kwiindawo zothumelo ngoomatshini ezinje ngeemoto, ukuhamba ngenqwelomoya, kunye nemigodi ngenxa yeenzuzo zazo ezinje nge-coefficient enkulu yokudibana, umthamo owomeleleyo wokuthwala, umlinganiselo omkhulu wothumelo, uthumelo olugudileyo, kunye nengxolo ephantsi. Iimpawu zayo zezi:
1. Isixhobo se-bevel esithe tye: Umgca wezinyo ngumgca othe tye, unqumla kwi-pex ye-cone, unciphisa izinyo.
2. I-Helical bevel gear: Umgca wezinyo ngumgca othe tye kwaye u-tangent ukuya kwinqanaba, ushwabana izinyo.
3. Iigiya ze-Spiral bevel: iigiya ezibuyiselwayo (zikwalungele iigiya ezinobude obulinganayo).
4. Cycloid spiral bevel gear: amazinyo econtour.
5. Zero degree spiral bevel gear: Amazinyo acutha kabini, βm=0, asetyenziselwa ukubuyisela iigiya ze-bevel ezithe tye, ngozinzo olungcono, kodwa hayi njengeegiya ezijikelezayo.
6. I-Cycloid tooth zero-degree bevel gear: Amazinyo eContour, βm=0, esetyenziselwa ukubuyisela iigiya ze-bevel ezithe tye, ngozinzo olungcono, kodwa hayi njengeegiya ezijikelezayo.
7. Iintlobo zobude bezinyo kwiigiya ze-spiral bevel zohlulwa ikakhulu zibe ngamazinyo acuthiweyo kunye nobude obulinganayo. Amazinyo acuthiweyo aquka ukucocwa kwentloko engalinganiyo amazinyo ancitshisiweyo, ukucocwa kwentloko ngokulinganayo amazinyo acuthiweyo kunye namazinyo acuthwe kabini.
8. Amazinyo eContour: amazinyo esiphelo esikhulu kunye nesiphelo esincinci anobude obufanayo, ngokuqhelekileyo asetyenziselwa i-oscillating bevel gears.
9. I-Non isotopic space amazinyo ashwabeneyo: i-apexes ye-sub-cone, i-cone ephezulu kunye ne-root cone zihambelana.
