Automotive iavkis tau tus mob ntau, thiab nws tau dav paub ntawm cov neeg uas muaj kev nkag siab yooj yim ntawm tsheb. Piv txwv muaj xws li lub tsheb kis tau tus mob, tsav ncej, qhov sib txawv, lub kauj iav, thiab txawm tias qee yam khoom siv hluav taws xob xws li lub zog qhov rais nqa, wiper, thiab hluav taws xob tuav tes. Txij li cov iav tau siv dav thiab ua lub luag haujlwm tseem ceeb hauv tsheb, hnub no peb yuav tham txog kev paub txog cov iav hauv tsheb.

Iav kis tau tus mob yog ib qho ntawm cov khoom siv dav dav hauv tsheb thiab muaj cov haujlwm tseem ceeb hauv qab no:

1. Kev hloov ceev: Los ntawm meshing ob lub zog sib txawv, qhov ceev ntawm lub iav tuaj yeem hloov tau. Piv txwv li, lub zog nyob rau hauv ib qho kev kis tau tus mob tuaj yeem txo lossis nce qhov nrawm ntawm lub cav kom ua tau raws li qhov xav tau ntawm lub tsheb ua haujlwm.
2. Torque hloov: Thaum meshing ob lub zog sib txawv, qhov ceev thiab torque kis los ntawm lub iav kuj hloov. Piv txwv xws li lub ntsiab reducer nyob rau hauv lub tsav ncej thiab lub tsheb kis tau tus mob.
3. Kev hloov kev taw qhia: Lub zog ntawm lub cav ntawm qee lub tsheb yog perpendicular mus rau cov kev taw qhia ntawm lub tsheb lub zog, yog li nws yuav tsum tau hloov cov kev taw qhia ntawm lub zog xa mus rau lub tsheb. Cov cuab yeej no feem ntau yog lub ntsiab reducer thiab qhov sib txawv hauv lub tsheb.
Hauv tsheb, qee qhov siv cov iav ncaj, thaum lwm tus siv cov iav helical. Cov iav ncaj qha muaj kev sib kis tau zoo thaum cov hniav sib txuas thiab tshem tawm tag nrho cov hniav dav tib lub sijhawm. Txawm li cas los xij, qhov tsis zoo yog qhov tsis zoo, kev cuam tshuam, thiab suab nrov. Ntawm qhov tod tes, helical gears muaj cov txheej txheem kev sib txuas ntawm cov hniav ntev dua thiab cov hniav ntau dua rau kev sib koom ua ke piv rau cov iav ncaj, ua rau kev sib kis tau yooj yim, muaj zog load bearing muaj peev xwm, thiab tsis tshua muaj suab nrov thiab cuam tshuam. Lub ntsiab tsis zoo ntawm helical zog yog tias lawv tsim axial rog thaum raug rau ib txwm muaj zog, yuav tsum tau thrust bearings yuav tsum tau ntsia, ua rau ib tug complex qauv.

Cov kev cai rauautomotive iavyog siab, lub iav lub cev yuav tsum muaj kev tiv thaiv siab rau kev puas tsuaj, cov hniav nto yuav tsum muaj zog tiv thaiv corrosion, hnav thiab muaj peev xwm sib koom ua ke, uas yog, nws yuav tsum tau cov hniav nto yuav tsum tawv thiab cov tub ntxhais yuav tawv. Yog li ntawd, kev siv tshuab ntawm lub tsheb iav kuj tseem nyuaj, nrog cov txheej txheem hauv qab no:
Txiav ➟ Forging ➟ Annealing ➟ Machining ➟ Ib Ntu Copper Plating ➟ Carburizing ➟ Quenching ➟ Kub Kub Kub ➟ Shot Peening ➟ Hniav Sib Tsoo (Fine Grinding)
Txoj kev ntawm kev ua cov iav no tsis tsuas yog muaj lub zog txaus thiab toughness, tab sis kuj muaj lub siab hardness thiab hnav tsis kam ntawm cov hniav nto.
