Iigiya zeCylindricalUkwenziwa kwezinto zokubala, eziqhele ukusetyenziselwa ukuhanjiswa kwamandla eshaft parallel, zifuna izibalo ezichanekileyo zokuqinisekisa ukusebenza kakuhle. Iiparamitha ezisisiseko ekufuneka ziqwalaselwe ziquka umlinganiselo wegiya, idiameter yepitch, kunye nokubala kwamazinyo egiya. Umyinge wegiya, unqunywe ngumlinganiselo wenani lamazinyo kwisixhobo sokuqhuba ukuya kwisixhobo esiqhutywayo, sichaphazela ngokuthe ngqo isantya kunye ne-torque yenkqubo.

Ukubala i-pitch diameter, sebenzisa ifomula:

I-Pitch Diameter=I-Diametral Pitch/Inani laMazinyo

apho i-diametral pitch linani lamazinyo nge-intshi nganye yedayamitha yegiya. Olunye ubalo oluphambili yimodyuli yegiya, enikwe ngu:
Imodyuli=Inani laMazinyo/Ububanzi beMithi

Ubalo oluchanekileyo lweprofayili yezinyo kunye nezithuba kubalulekile ukukhusela imiba ye-meshing kunye nokuqinisekisa ukusebenza kakuhle. Ukongeza, ukujonga ulungelelwaniso olufanelekileyo lwegiya kunye nokubuyela umva kubalulekile ukugcina ukusebenza kunye nokuphila ixesha elide. Olu balo lunceda ekuyileni iigiya ezisebenza ngokufanelekileyo, ezomeleleyo, nezilungele ukusetyenziswa kwazo.
