Inani lamazinyo abonakalayo kwiigiya yebhevelyingcamango esetyenziselwa ukuchaza ijiyometri yeegiya ze-bevel. Ngokungafaniyo neegiya ze-spur, ezinobubanzi obungaguqukiyo bepitch, iigiya ze-bevel zine-pitch diameters ezahlukeneyo kumazinyo azo. Inani lamazinyo elibonakalayo yiparameter ecingelwayo enceda ukubonisa iimpawu ezifanayo zokuzibandakanya kwe-aigiya yebhevelngendlela efana negiya ye-spur.

Kwiigiya yebhevel, iprofayili yamazinyo igobile, kwaye ububanzi bepitch buyatshintsha kubude bezinyo. Inani lamazinyo elibonakalayo limiselwa ngokuqwalasela igiya elilinganayo le-spur eliya kuba nobubanzi bepitch obufanayo kwaye libonelele ngeempawu ezifanayo zokubandakanya izinyo. Lixabiso lethiyori elenza lula uhlalutyo kunye noyilo lweegiya ze-bevel.

Ingcamango yenani lamazinyo elibonakalayo iluncedo ngakumbi ekubaleni okunxulumene noyilo, ukwenziwa, kunye nohlalutyo lweegiya ze-bevel. Ivumela iinjineli ukuba zisebenzise iifomyula eziqhelekileyo kunye neendlela ezisetyenziswa kwiigiya ze-spur ukuzeiigiya zebhevel, okwenza inkqubo yoyilo ibe lula ngakumbi.

Ukuze babale inani lamazinyo abonakalayo kwigiya ye-bevel, iinjineli zisebenzisa inguqu yemathematika eqwalasela i-engile yekhoni yepitch yegiya ye-bevel. Le fomula yile ilandelayo:

Ngokwenyani=Eyokwenene/cos(δ)

apho:

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

   

  I-Zvirtual linani lamazinyo elibonakalayo,

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

   

  I-Zactual​ linani lamazinyo akwigiya ye-bevel,

• 
  $\delta \backslash delta$

   

  I-δ yi-engile yekhowuni yepitch yegiya ye-bevel.

Olu balo luvelisa inani lamazinyo abonakalayo kwigiya elinganayo ye-spur eya kusebenza ngokufanayo ngokweembambo zepitch kunye neempawu zokujikeleza njengegiya ye-bevel. Ngokusebenzisa eli nani libonakalayo, iinjineli zingasebenzisa iifomyula zegiya ye-spur ukuvavanya iimpawu eziphambili ezifana namandla okugoba, uxinzelelo loqhagamshelwano, kunye nezinye izinto ezithwala umthwalo. Le ndlela iluncedo ngakumbi kuyilo lwegiya ye-bevel apho ukuchaneka kunye nokusebenza kubaluleke kakhulu, njengakwii-differentials zeemoto, izinto ze-aerospace, kunye noomatshini bemizi-mveliso.

Kwiigiya ze-helical kunye ne-spiral bevel, inani lamazinyo elibonakalayo likwanceda xa kuyilwa iigiya ezifuna inqanaba eliphezulu lokuchaneka kwizakhono zazo zokudibanisa kunye nokwabelana ngomthwalo. Le ngcamango ivumela ezi milo zegiya zintsonkothileyo ukuba zenziwe lula, iququzelela iinkqubo zokuvelisa kwaye iphucule ukuqina ngokuphucula i-geometry yamazinyo ngokusekelwe kwiiparamitha zegiya ze-spur eziqondwa kakuhle.

Inani lamazinyo abonakalayo kwigiya ye-bevel liguqula inkqubo yegiya entsonkothileyo ye-conical ibe yimodeli yegiya ye-spur efanayo, okwenza kube lula ukubala kunye neenkqubo zoyilo. Le ndlela iphucula ukuchaneka kwezibikezelo zokusebenza kwaye inceda iinjineli ekuqinisekiseni ukuba igiya inokusingatha umthwalo ofunekayo, isantya sokujikeleza, kunye noxinzelelo. Le ngcamango lilitye lesiseko kubunjineli begiya ye-bevel, evumela uyilo olusebenzayo, oluchanekileyo, noluthembekileyo kwizicelo ezahlukeneyo zokusebenza okuphezulu.
