1. Cov khoom sib txawv
1. Bevel Zog: Zog uas tau siv los hloov cov lus tsa suab thiab lub zog nruab nrab ntawm ob qho kev sib tshuam.
2. Helical zog: txo cov khoom siv kis.
2. Cov yam ntxwv sib txawv
1. Cov yam ntxwv ntawm Bevel lub zog: qhov sib tshuam lub kaum sab xis ntawm ob lub axes ntawm bevel iav yog sib npaug rau 90 degree).
2. Cov yam ntxwv ntawm Helical zog: loj me me, lub teeb hnyav, loj dua kev sib txuas, zoo tuaj yeem xaiv cov haujlwm txuas ntxiv raws li cov neeg siv khoom xav tau.
Helical lub zog tsis tag kauv kiag li zog. Nws yuav tsum tau hais tias helical zog yog cov meshing hom ntawm ob helical zog, thiab lawv tuaj yeem txawv txav hauv kev sib txawv cov lus qhia hauv qhov chaw. Cov tshuaj nplaum zoo tib yam ua ke nrog tus hniav dav tib lub sijhawm, ua kom muaj kev cuam tshuam kis tau thiab tsis ruaj khov. Helical iav kis tau zoo dua rau spur iav kis, thiab qhov chaw sib nrug sib nrug yog siv thaum muaj kev kub ceev thiab hnyav.
Kev tsim ntawm Bevel iav cov hniav profile yog zoo li ntawm cov iav cylindrical, tsuas yog tias ib qho hauv qab lub khob yog siv hloov chaw hauv qab. Bevel lub zog yog siv los xa cov lus taw thiab hluav taws xob nruab nrab ntawm ob qhov sib tshuam. Feem ntau machinery, cov kev sib tshuam ntawm ob tug axes ntawm bevel gears yog sib npaug rau 90 degree (tab sis nws yuav tsis sib npaug nrog 90 degree).
