Thaum nws los txog rau xaiv cov khoom tsim nyog rau helical thiabbevel iav, ob peb yam yuav tsum tau txiav txim siab los xyuas kom meej qhov ua tau zoo thiab ua haujlwm ntev. Ob hom iav ua lub luag haujlwm tseem ceeb hauv ntau lub tshuab tshuab, thiab xaiv cov khoom tsim nyog yog qhov tseem ceeb rau lawv txoj haujlwm thiab kev ntseeg tau.

Ua ntej, cia peb ua tib zoo saibhelical iav. Cov iav no muaj lawv cov hniav txiav ntawm lub kaum sab xis rau lub iav axis, ua rau kev ua haujlwm zoo dua thiab ntsiag to piv rau cov iav spur. Helical iav feem ntau yog siv rau hauv cov ntawv thov uas xav tau kev kub ceev thiab hnyav, xws li kev xa tsheb, kev siv tshuab, thiab cov khoom siv hluav taws xob.

Ib qho ntawm cov khoom siv nrov tshaj plaws rau cov iav helical yog hlau. Steel muaj lub zog zoo heev, hnav tsis kam, thiab kav ntev, ua rau nws tsim nyog rau kev xav tau kev ua haujlwm. Tsis tas li ntawd, cov txheej txheem carburizing thiab kev kho cua sov tuaj yeem txhim kho qhov tawv tawv thiab hnav tsis kam ntawm steel helical iav, ua rau lawv lub neej kev pab ntev.

Nyob rau hauv xyoo tas los no, cov ntaub ntawv siab heev xws li rooj plaub-hardened steel thiab nitrided steel tau txais qhov chaw zoo rau cov iav helical. Cov ntaub ntawv no muab kev hnav zoo tshaj plaws thiab qaug zog, ua rau lawv zoo tagnrho rau cov ntawv siv hnyav uas muaj kev ntseeg siab yog qhov tseem ceeb. Tsis tas li ntawd, kev siv cov thev naus laus zis thev naus laus zis, xws li pob zeb diamond zoo li cov pa roj carbon (DLC) txheej, tuaj yeem txhim kho kev ua tau zoo thiab kev ua haujlwm ntev ntawm cov iav helical, tshwj xeeb tshaj yog nyob rau hauv high-temperature thiab hnyav load puag ncig.

Ntawm qhov tod tes,bevel iavyog siv los hloov lub zog ntawm kev sib tshuam shafts, thiab lawv tuaj yeem muab faib ua ncaj bevel, kauv bevel, thiab hypoid bevel gears. Cov iav no feem ntau pom muaj nyob rau hauv tsheb sib txawv, marine propulsion systems, thiab cov tshuab hnyav.

Kev xaiv cov khoom siv raubevel iavyog cuam tshuam los ntawm yam xws li kev khiav hauj lwm ceev, load peev xwm, thiab iav geometry. Hlau yog cov khoom siv rau feem ntau bevel iav vim nws lub zog siab thiab toughness. Hauv cov ntawv thov uas lub suab nrov thiab kev vibration yog qhov tseem ceeb, cov alloys xws li tooj liab lossis tooj dag tuaj yeem siv los txo cov iav meshing cuam tshuam thiab txhim kho tag nrho kev ua haujlwm du.

Ntxiv nrog rau cov hlau, qee cov tuam ntxhab kuj tseem siv cov khoom siv hlau sintered rau bevel iav. Sintered iav yog tsim los ntawm compacting hlau hmoov nyob rau hauv siab siab thiab ces sintering lawv nyob rau hauv siab kub. Cov txheej txheem tsim khoom no ua rau cov iav nrog cov hniav zoo meej thiab qhov tseeb qhov tseeb, ua rau lawv tsim nyog rau cov ntawv thov uas muaj kev ua haujlwm siab thiab tsis tshua muaj suab nrov.

Hauv kev xaus, kev xaiv cov khoom siv rau helical thiab bevel gears nyob ntawm qhov kev thov tshwj xeeb, suav nrog lub peev xwm thauj khoom, kev ua haujlwm, thiab cov yam ntxwv xav tau. Thaum cov hlau tseem yog cov khoom siv mus rau feem ntau cov ntawv siv iav, cov khoom siv siab heev thiab cov txheej txheem tsim khoom txuas ntxiv thawb cov ciam teb ntawm iav kev ua tau zoo, muab kev txhim kho kev ua tau zoo, kev ntseeg tau, thiab kav ntev. Thaum kawg, kev sab laj nrog tus kws tsim khoom tsim nyog lossis cov chaw tsim khoom iav yog qhov tseem ceeb los txiav txim siab cov khoom siv zoo tshaj plaws rau helical thiabbevel iavraws li qhov tshwj xeeb xav tau ntawm daim ntawv thov npaj.
