Enye yeempawu ezibalaseleyo zedigri zeroiigiya ze-bevel ezijikelezayoluyilo lwamazinyo awodwa, oluvumela ukusebenza ngokutyibilikayo nokuzola xa kuthelekiswa neegiya zebevel ezithe tye. Ilungiselelo le-helical lamazinyo liququzelela ukubandakanyeka ngokuthe ngcembe, ukunciphisa imithwalo yothuso kunye nokunxiba. Olu phawu luluncedo ngakumbi kwimisebenzi enzima efana noomatshini bokwakha, apho ukuthembeka kunye nokuqina kubalulekile.

Kwizicelo zokunciphisa, i-spiral degree zero bevel gears inceda ekufezekiseni ukuncipha kwesantya esichanekileyo ngelixa ugcina ukuhanjiswa kwetorque ephezulu. Oku kusebenza kakuhle kubalulekile koomatshini abasebenza phantsi kweemeko ezahlukeneyo zomthwalo. Kwiilori, ezi giya zinegalelo ekusebenzeni ngokubanzi kwe-drivetrain, ukuqinisekisa ukuba amandla ahanjiswa ngokutyibilikayo ukusuka enjini ukuya kumavili, okwandisa ukunyathela kunye nokuphatha, ngakumbi kwiindawo ezicela umngeni.

Ngaphaya koko, inkqubo yokwenziwa kwezi giya ifuna ukuchaneka okuphezulu ukuze kuqinisekiswe i-meshing efanelekileyo kunye ne-backlash encinci, echaphazela ngokuthe ngqo ukusebenza kunye nobomi. Njengoko imizi-mveliso iqhubeka nokufuna oomatshini bomelele ngakumbi nabasebenzayo, ukubaluleka kweegiya ze-spiral zero zero bevel kwizicelo zobunjineli zanamhlanje azinakugqithwa. Badlala indima ebalulekileyo ekwandiseni ukusebenza kakuhle kunye nokwandisa ixesha elide lezixhobo kumacandelo asusela kulwakhiwo ukuya kwezothutho.
