Spiral bevel iav, cov axes ntawm cov iav tsav thiab cov iav tsav sib tshuam ntawm ib qho taw tes, thiab lub kaum sab xis ntawm kev sib tshuam tuaj yeem ua tau raws li qhov xav tau, tab sis feem ntau ntawm cov qag tsav tsheb, cov iav reducer tseem ceeb tau teeb tsa ntsug ntawm lub kaum sab xis 90 °. Vim yog qhov sib tshooj ntawm cov ntsej muag kawg ntawm cov hniav iav, tsawg kawg yog ob lossis ntau khub ntawm cov hniav iav sib txuas tib lub sijhawm. Yog li ntawd, cov iav bevel tuaj yeem tiv taus lub nra hnyav dua. Tsis tas li ntawd, cov hniav iav tsis sib txuas tib lub sijhawm hla tag nrho cov hniav ntev, tab sis maj mam sib txuas los ntawm cov hniav. Ib qho kawg yog tig mus rau lwm qhov kawg, yog li nws ua haujlwm zoo, thiab txawm tias ntawm qhov ceev ceev, lub suab nrov thiab kev co me me heev.

Cov iav kauv bevel yog ib hom iav bevel uas muaj cov hniav nkhaus, helical. Feem ntau siv rau hauv cov sib txawv ntawm lub tsheb, lawv hloov pauv lub zog ntawm lub kaum sab xis 90-degree los ntawm lub qag tsav mus rau lub log. Piv rau cov iav bevel ncaj, lawv cov hniav kauv tsim ua kom muaj kev sib txuas du, txo kev co, thiab ua haujlwm ntsiag to ua rau lawv zoo tagnrho rau kev siv tsheb thiab kev lag luam.

1. Cov lus sab xis thiab sab laug kuj siv tas li ntawm cov iav sib dhos, cov iav hypoid, thiab cov iav ntsej muag hniav skew.

2. Ib yam li lwm hom iav, cov iav bevel spiral, cov iav hypoid, thiab cov iav ntsej muag nrog cov hniav angled yog xaiv ua sab tes xis lossis sab laug raws li lawv qhov kev taw qhia helix.

3. Kev faib tawm sab xis thiab sab laug feem ntau siv rau cov iav bevel, cov iav hypoid, thiab cov iav ntsej muag nrog cov hniav oblique.

4. Ib yam li lwm cov iav hniav oblique, cov iav bevel thiab hypoid tau txheeb xyuas los ntawm sab tes xis lossis sab laug nyob ntawm qhov kev taw qhia ntawm cov hniav.

5. Hauv cov lus siv rau cov iav, cov lus xaiv sab xis thiab sab laug siv tau rau cov iav sib dhos, cov iav hypoid, thiab cov iav angled.

Cov iav Hypoid, cov axes ntawm cov iav tsav thiab cov iav tsav tsis sib tshuam tab sis sib tshuam hauv qhov chaw. Cov kaum sib tshuam ntawm cov iav hypoid feem ntau yog perpendicular rau ntau lub dav hlau ntawm lub kaum sab xis 90 °. Lub iav tsav muaj qhov offset upward lossis downward piv rau lub iav tsav (hu ua qhov offset sab saud lossis qis dua raws li). Thaum qhov offset loj mus rau qee qhov, ib lub iav tsav tuaj yeem hla dhau lwm lub iav tsav. Ua li no, cov kabmob compact tuaj yeem npaj rau ob sab ntawm txhua lub iav, uas yog qhov zoo rau kev txhim kho kev txhawb nqa rigidity thiab xyuas kom meej qhov tseeb meshing ntawm cov hniav iav, yog li ua kom lub neej ntawm cov iav ntev dua. Nws yog qhov tsim nyog rau cov qag tsav los ntawm hom.

Tsis zoo licov iav bevel spiral qhov twg lub kaum sab xis ntawm lub iav tsav thiab lub iav tsav sib npaug vim tias cov axes ntawm cov iav khub sib tshuam, qhov axis offset ntawm cov iav hypoid ua rau lub kaum sab xis ntawm lub iav tsav helix loj dua lub kaum sab xis ntawm lub iav tsav helix. Yog li ntawd, txawm hais tias qhov modulus ib txwm ntawm cov iav hypoid bevel yog sib npaug, qhov kawg ntawm lub ntsej muag modulus tsis sib npaug (qhov kawg ntawm lub ntsej muag modulus ntawm cov iav tsav yog loj dua qhov kawg ntawm lub ntsej muag modulus ntawm cov iav tsav). Qhov no ua rau lub iav tsav ntawm quasi ob sab bevel iav kis tau muaj lub cheeb loj dua thiab muaj zog dua thiab ruaj khov dua li lub iav tsav ntawm cov iav sib xws. Tsis tas li ntawd, vim yog lub cheeb loj thiab lub kaum sab xis ntawm lub iav tsav ntawm cov iav hypoid bevel, kev ntxhov siab ntawm qhov chaw hniav raug txo qis thiab lub neej ua haujlwm nce ntxiv.

Txawm li cas los xij, thaum lub kis tau me me, lub iav tsav ntawm lub quasi ob sab bevel iav kis tau loj dhau piv rau lub iav tsav ntawm lub iav spiral bevel. Lub sijhawm no, nws yog qhov tsim nyog dua los xaiv lub iav spiral bevel.
