Thaum nws los txog rau kev xaiv cov khoom siv zoo rau helical thiabcov iav bevel, ntau yam yuav tsum tau xav txog kom ntseeg tau tias muaj kev ua tau zoo tshaj plaws thiab lub neej ntev. Ob hom iav ua lub luag haujlwm tseem ceeb hauv ntau yam tshuab, thiab kev xaiv cov khoom siv tsim nyog yog qhov tseem ceeb rau lawv txoj haujlwm thiab kev ntseeg tau.

Ua ntej, cia peb saib ze duacov iav helicalCov iav no muaj lawv cov hniav txiav ntawm lub kaum sab xis rau lub iav axis, ua rau kev ua haujlwm du thiab ntsiag to dua piv rau cov iav spur. Cov iav helical feem ntau siv rau hauv cov ntawv thov uas xav tau kev kub ceev thiab cov khoom hnyav, xws li kev sib kis tsheb, cov tshuab kev lag luam, thiab cov khoom siv hluav taws xob.

Ib qho ntawm cov ntaub ntawv nrov tshaj plaws rau cov iav helical yog hlau. Hlau muaj lub zog zoo heev, tiv taus kev hnav, thiab ruaj khov, ua rau nws haum rau cov xwm txheej ua haujlwm nyuaj. Tsis tas li ntawd, cov txheej txheem carburizing thiab kev kho cua sov tuaj yeem txhim kho qhov nyuaj ntawm qhov chaw thiab kev tiv taus kev hnav ntawm cov iav helical hlau, ua rau lawv lub neej ua haujlwm ntev.

Nyob rau xyoo tas los no, cov ntaub ntawv siab heev xws li cov hlau uas tau ua kom tawv thiab cov hlau nitrided tau nrov heev rau cov iav helical. Cov ntaub ntawv no muaj kev tiv thaiv kev hnav zoo dua thiab lub zog qaug zog, ua rau lawv zoo tagnrho rau cov ntawv thov hnyav uas qhov kev ntseeg siab yog qhov tseem ceeb. Ntxiv mus, kev siv cov txheej txheem txheej txheem siab heev, xws li cov txheej txheem carbon zoo li pob zeb diamond (DLC), tuaj yeem txhim kho kev ua tau zoo thiab lub neej ntev ntawm cov iav helical, tshwj xeeb tshaj yog nyob rau hauv qhov kub thiab txias heev.

Nyob rau sab tes tod,cov iav bevelyog siv los hloov lub zog ntawm cov ncej sib tshuam, thiab lawv tuaj yeem muab faib ua cov iav bevel ncaj, cov iav bevel kauv, thiab cov iav hypoid bevel. Cov iav no feem ntau pom muaj nyob rau hauv cov khoom sib txawv ntawm tsheb, cov tshuab tsav nkoj, thiab cov tshuab hnyav.

Kev xaiv cov khoom siv raucov iav bevelraug cuam tshuam los ntawm cov yam xws li kev ua haujlwm ceev, lub peev xwm thauj khoom, thiab cov qauv iav. Hlau yog cov khoom siv nyiam rau feem ntau cov iav bevel vim nws lub zog siab thiab kev tawv. Hauv cov ntawv thov uas suab nrov thiab kev co yog cov yam tseem ceeb, cov hlau xws li tooj dag lossis tooj dag yuav raug siv los txo qhov cuam tshuam ntawm cov iav meshing thiab txhim kho kev ua haujlwm du.

Ntxiv rau hlau, qee cov chaw tsim khoom kuj siv cov khoom siv hlau sintered rau cov iav bevel. Cov iav sintered yog ua los ntawm kev sib xyaw cov hmoov hlau hauv qab siab thiab tom qab ntawd sintering lawv ntawm qhov kub siab. Cov txheej txheem tsim khoom no ua rau cov iav nrog cov hniav profile meej thiab qhov tseeb zoo heev, ua rau lawv haum rau cov ntawv thov nrog kev ua haujlwm siab thiab suab nrov qis.

Xaus lus, qhov kev xaiv cov khoom siv rau cov iav helical thiab bevel nyob ntawm qhov xav tau ntawm daim ntawv thov tshwj xeeb, suav nrog lub peev xwm thauj khoom, cov xwm txheej ua haujlwm, thiab cov yam ntxwv kev ua tau zoo. Thaum hlau tseem yog cov khoom siv mus rau feem ntau cov ntawv thov iav, cov ntaub ntawv siab heev thiab cov txheej txheem tsim khoom txuas ntxiv thawb cov ciam teb ntawm kev ua tau zoo ntawm iav, muab kev ua haujlwm zoo dua, kev ntseeg siab, thiab kev ruaj khov. Thaum kawg, kev sab laj nrog tus kws ua haujlwm tsim nyog lossis tus tsim khoom iav yog qhov tseem ceeb los txiav txim siab cov khoom siv zoo tshaj plaws rau helical thiabcov iav bevelraws li qhov xav tau tshwj xeeb ntawm daim ntawv thov uas tau npaj tseg.
