Inombolo ebonakalayo yamazinyo ku-aigiya le-bevelumqondo osetshenziswa ukukhombisa i-geometry yamagiya e-bevel. Ngokungafani namagiya e-spur, anobubanzi obungashintshi bephimbo, amagiya e-bevel anobubanzi obuhlukahlukene bephimbo emazinyweni awo. Inombolo ebonakalayo yamazinyo ipharamitha ecatshangelwayo esiza ukuveza izici ezilinganayo zokubandakanyeka kwe-aigiya le-bevelngendlela eqhathaniseka negiya le-spur.

Phakathi kuigiya le-bevel, iphrofayili yezinyo igobile, futhi ububanzi bephimbo buyashintsha ngokuhambisana nobude bezinyo. Inombolo ebonakalayo yamazinyo inqunywa ngokucabangela igiya le-spur elilinganayo elingaba nobubanzi bephimbo elifanayo futhi linikeze izici ezifanayo zokubandakanya izinyo. Kuyivelu yethiyori eyenza ukuhlaziya nokwakheka kwamagiya e-bevel kube lula.

Umqondo wenombolo ebonakalayo yamazinyo uwusizo ikakhulukazi ekubaleni okuhlobene nomklamo, ukukhiqizwa, nokuhlaziywa kwamagiya e-bevel. Ivumela onjiniyela ukuthi basebenzise amafomula ajwayelekile nezindlela ezisetshenziselwa amagiya e-spuramagiya e-bevel, okwenza inqubo yokuklama iqonde kakhudlwana.

Ukuze ubale inombolo ebonakalayo yamazinyo egiyeni le-bevel, onjiniyela basebenzisa ukuguqulwa kwezibalo okucabangela i-engeli yekhoni yokuphakama yegiya le-bevel. Ifomula imi kanje:

I-Zvirtual=Zactual/cos(δ)

kuphi:

• 
  $ZvirtualZ\_\{\backslash text\{virtual\}\}$

   

  I-Zvirtual inombolo engokoqobo yamazinyo,

• 
  $ZactualZ\_\{\backslash text\{actual\}\}$

   

  I-Zactual iyinani langempela lamazinyo egiyeni le-bevel,

• 
  $\delta \backslash delta$

   

  δ i-engeli ye-pitch cone yegiya le-bevel.

Lesi sibalo siveza isibalo samazinyo esibonakalayo segiya le-spur elilinganayo elingenza okufanayo ngokuya ngobubanzi bephitshi nezici zokuzungezisa njengegiya le-bevel. Ngokusebenzisa le nombolo ebonakalayo, onjiniyela bangasebenzisa amafomula egiya le-spur ukuze bahlole izici ezibalulekile ezifana namandla okugoba, ingcindezi yokuxhumana, nezinye izici ezithwala umthwalo. Le ndlela iwusizo ikakhulukazi emiklamo yegiya le-bevel lapho ukunemba nokusebenza kubaluleke kakhulu, njengokuhluka kwezimoto, izingxenye ze-aerospace, nemishini yezimboni.

Ngamagiya e-helical kanye ne-spiral bevel, inombolo ebonakalayo yamazinyo futhi iyasiza lapho uklama amagiya adinga izinga eliphezulu lokunemba kukhono lawo lokuhlanganisa kanye nokwabelana ngomthwalo. Lo mqondo uvumela lezi zimo zegiya eziyinkimbinkimbi kakhulu ukuthi zenziwe lula, kube lula izinqubo zokukhiqiza kanye nokuthuthukisa ukuqina ngokuthuthukisa ijometri yamazinyo ngokusekelwe kumapharamitha aqondwa kahle we-spur.

inombolo ebonakalayo yamazinyo egiyeni le-bevel iguqula isistimu yegiya eliyindilinga ibe imodeli yegiya le-spur efanayo, yenza izibalo zibe lula nezinqubo zokuklama. Le ndlela ithuthukisa ukunemba kwezibikezelo zokusebenza futhi isiza onjiniyela ekuqinisekiseni ukuthi igiya liyakwazi ukuthwala umthwalo odingekayo, isivinini sokujikeleza, kanye nengcindezi. Umqondo uyitshe legumbi kubunjiniyela begiya le-bevel, ovumela imiklamo esebenza kahle, enembe, nethembekile ezinhlelweni zokusebenza ezahlukahlukene ezisebenza kahle.
