Kev lag luam kev tsim khoom siv tshuab xav tau ntau hom iav los ua haujlwm tshwj xeeb thiab ua tau raws li cov kev cai. Nov yog qee yam hom iav thiab lawv cov haujlwm:

1. Cylindrical iav: dav siv nyob rau hauv bearings los muab torque thiab hloov zog.
2. Bevel iav: siv nyob rau hauv rooj plaub uas cov bearings kuj tilted kom ua tau zoo dua kis tau tus mob.
3. Worm iav: siv los muab kev sib kis ntau dua, feem ntau siv nyob rau hauv high-speed low-torque.
4. Helical gears: siv los muab kev sib kis siab torque thiab daws qhov teeb meem ntawm qhov chaw axial txwv.
5. Txo cov zog: siv los txo qhov ceev ntawm kev tsav tsheb kom ua tiav cov khoom siv tswj kom zoo.

Ntxiv nrog rau cov haujlwm saum toj no, lub zog kuj yuav tsum tau ua kom tau raws li qee qhov kev xav tau, xws li:

1. Cov kev xav tau Precision: qhov tseeb ntawm lub iav muaj qhov cuam tshuam loj rau kev ua haujlwm ntawm lub cev.
2. Hnav tsis kam: lub iav yuav tsum ua kom ruaj khov kom haum rau kev siv mus ntev.
3. Thermal stability: lub iav yuav tsum muaj thermal stability zoo kom muaj kev sib kis tau zoo.
4. Cov khoom siv zoo: lub iav yuav tsum tau tsim los ntawm cov ntaub ntawv zoo kom ntseeg tau tias nws ruaj khov thiab kav ntev.

Cov no yog cov kev cai ntawm kev lag luam kev lag luam mechanical rau cov iav.
