Cov iav yog cov khoom siv kho tshuab tseem ceeb uas siv rau hauv ntau daim ntawv thov thoob plaws kev tsim khoom, tsheb, neeg hlau, thiab kev lag luam aerospace. Ntawm lawv,cov iav bevel, helical gears, thiab spur gears yog peb hom siv dav dav, txhua tus tsim los rau cov haujlwm tshwj xeeb. Kev nkag siab txog lawv cov yam ntxwv tsim thiab qhov sib txawv yog qhov tseem ceeb rau kev xaiv cov iav zoo rau lub tshuab.

Dab tsi yog Bevel Gear

Muaj ntau homcov iav bevelsuav nrog:

Cov iav bevel ncajnrog cov hniav ncaj thiab daim ntawv conical yooj yim.

Cov iav kauv beveltau tsim los nrog cov hniav nkhaus kom muab kev ua haujlwm du thiab ntsiag to, tshwj xeeb tshaj yog nyob rau hauv kev kub ceev lossis kev siv hnyav.

Hypoid bevel iav ：zoo ib yam li cov iav kauv bevel, tab sis cov axes tsis sib tshuam; feem ntau siv rau hauv cov qag tsheb tom qab.

Cov iav bevel yog qhov zoo tagnrho thaum lub zog torque xav tau kis ntawm cov ncej ntawm lub kaum sab xis, nrog kev ua haujlwm siab thiab compactness.

Spur Gears vs Helical Gears
Thaum cov iav bevel ua haujlwm nrog cov ncej sib tshuam, cov iav spur thiab helical feem ntau yog siv rau cov ntawv thov ncej sib luag. Txawm li cas los xij, txoj kev uas lawv cov hniav raug txiav cuam tshuam rau lawv cov yam ntxwv kev ua tau zoo.

Spur Gears
Cov iav spur yog hom iav yooj yim tshaj plaws, nrog cov hniav ncaj uas sib dhos sib luag rau lub axis ntawm kev tig. Lawv cov txiaj ntsig suav nrog:

Tsim thiab tsim khoom yooj yim

Kev ua haujlwm siab hauv kev xa xov torque

Haum rau qhov ceev qis mus rau nruab nrab

Txawm li cas los xij, cov iav spur feem ntau tsim suab nrov thiab kev co ntawm qhov ceev dua vim yog kev sib koom ua ke ntawm cov hniav. Qhov no ua rau lawv tsis haum rau kev siv ceev lossis kev thauj khoom siab.

Helical Gears
Cov iav helical, qhov sib piv, muaj cov hniav uas raug txiav ntawm lub kaum sab xis rau lub iav axis, tsim ib lub helix. Tus qauv tsim no muaj ntau qhov zoo:

Kev ua haujlwm du thiab ntsiag to vim yog kev sib txhuam hniav maj mam

Muaj peev xwm nqa tau ntau dua, vim muaj ntau cov hniav sib cuag txhua lub sijhawm

Kev ua tau zoo dua ntawm kev kub ceev

Txawm li cas los xij, cov iav helical tsim cov axial thrust, uas yuav tsum tau suav nrog hauv kev tsim qauv los ntawm cov bearings lossis thrust washers tsim nyog. Lawv kuj tseem nyuaj me ntsis thiab kim dua rau kev tsim dua li cov iav spur.
Cov iav bevel yog qhov zoo tagnrho rau kev hloov pauv qhov kev taw qhia ntawm torque ntawm cov ncej sib tshuam, feem ntau ntawm 90 degrees.

Cov iav spur yog cov nqi tsim nyog thiab tsim nyog rau kev siv yooj yim, qis-ceev, qis-load nrog cov ncej sib luag.

Cov iav helicalmuab kev ua tau zoo dua ntawm qhov ceev dua, nrog rau suab nrov txo qis thiab kev ua haujlwm du dua, ua rau lawv zoo dua rau cov chaw xav tau ntau dua.

Kev xaiv hom iav kom raug nyob ntawm seb koj daim ntawv thov ceev npaum li cas, qhov hnyav npaum li cas, qhov kev taw qhia ntawm lub qag, thiab qhov kev txwv ntawm suab nrov. Kev nkag siab txog qhov sib txawv no pab cov engineers tsim cov txheej txheem kho tshuab uas txhim khu kev qha thiab ua haujlwm tau zoo dua.
