Umlinganiselo wegiya ye-bevel unokubalwa kusetyenziswa ifomyula:
Umlinganiselo weGear = (Inani laMazinyo kwiGear eqhutywayo) / (Inani laMazinyo kwiGear yokuQhuba)
Kwi izixhobo ze-bevelinkqubo, igiya yokuqhuba yeyona idlulisela amandla kwigiya eqhutywayo.Inani lamazinyo kwigiya nganye limisela ubungakanani bazo kunye nezantya zokujikeleza.Ngokwahlula inani lamazinyo kwisixhobo esiqhutywayo ngenani lamazinyo kwisixhobo sokuqhuba, unokumisela umlinganiselo wegiya.
Umzekelo, ukuba igiya yokuqhuba inamazinyo angama-20 kwaye igiya eqhutywayo inamazinyo angama-40, umlinganiselo wegiya uya kuba:
Umlinganiselo weGear = 40/20 = 2
Oku kuthetha ukuba kwinguqu nganye yesixhobo sokuqhuba, isixhobo esiqhutywayo siya kujikeleza kabini.Umlinganiselo wegiya umisela isantya kunye nobudlelwane betorque phakathi kokuqhuba kunye nezixhobo eziqhutywayo kwiinkqubo yegiya ye-bevel.
