Gears yog cov cuab yeej siv kho tshuab siv hauv suav tsis txheeb hauv kev tsim khoom, tsheb, neeg hlau, thiab kev lag luam aerospace. Ntawm lawv,bevel iav, helical gears, thiab spur gears yog peb hom siv dav, txhua tus tsim los rau cov haujlwm tshwj xeeb. Kev nkag siab txog lawv cov qauv tsim thiab qhov sib txawv yog qhov tseem ceeb rau kev xaiv cov iav zoo rau lub tshuab tshuab.

Dab tsi yog Bevel iav

Muaj ob peb hombevel iavsuav nrog:

Ncaj bevel iavnrog cov hniav ncaj thiab ib daim ntawv yooj yim conical.

Kauv bevel iavyog 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 hnyav load daim ntawv thov.

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

Bevel iav yog qhov zoo tshaj plaws thaum lub zog xav tau kev sib kis ntawm cov ncej ntawm lub kaum sab xis, nrog kev ua haujlwm siab thiab kev cog lus.

Spur Gears vs Helical Gears
Thaum cov iav bevel ua haujlwm nrog kev sib tshuam shafts, spur thiab helical iav feem ntau yog siv rau cov ntawv sib txuas ua ke. Txawm li cas los xij, txoj kev lawv cov hniav raug txiav tseem ceeb cuam tshuam rau lawv cov yam ntxwv ua haujlwm.

Spur Gears
Spur iav yog hom yooj yim tshaj plaws ntawm cov iav, nrog cov hniav ncaj uas ua raws li qhov sib npaug ntawm cov axis ntawm kev sib hloov. Lawv qhov zoo muaj xws li:

Yooj yim tsim thiab tsim khoom

High efficiency nyob rau hauv kis torque

Haum rau kev ceev qis mus rau nruab nrab

Txawm li cas los xij, spur gears zoo li ua suab nrov thiab poob siab ntawm qhov nrawm dua vim qhov kev koom tes ntawm cov hniav tam sim ntawd. Qhov no ua rau lawv tsis haum rau kev siv high-speed lossis high-load.

Helical iav
Helical iav, nyob rau hauv sib piv, muaj cov hniav uas raug txiav ntawm lub kaum sab xis ntawm lub iav axis, tsim ib lub helix. Qhov kev tsim no muaj ntau yam zoo:

Kev ua haujlwm du thiab ntsiag to vim kev sib txuas ntawm cov hniav

Lub peev xwm nqa tau siab dua, vim tias cov hniav ntau dua nyob rau hauv kev sib cuag txhua lub sijhawm

Kev ua tau zoo dua ntawm kev kub ceev

Txawm li cas los xij, helical gears tsim axial thrust, uas yuav tsum tau suav rau hauv cov qauv tsim los ntawm cov bearings tsim nyog lossis thrust washers. Lawv kuj yog ib qho nyuaj me ntsis thiab raug nqi tsim khoom dua li cov iav spur.
Bevel iav yog qhov zoo tagnrho rau kev hloov cov kev taw qhia ntawm torque ntawm kev sib tshuam shafts, feem ntau ntawm 90 degrees.

Spur iav yog tus nqi-zoo thiab haum rau kev yooj yim, qis-ceev, qis-load daim ntaub ntawv nrog rau qhov sib npaug.

Helical iavmuab kev txhim kho kev ua tau zoo ntawm kev nrawm dua, nrog txo suab nrov thiab ua haujlwm zoo dua, ua rau lawv nyiam rau qhov xav tau ntau dua.

Xaiv hom iav zoo nyob ntawm koj daim ntawv thov ceev, thauj khoom, kev taw qhia ncej, thiab suab nrov txwv. Kev nkag siab txog qhov sib txawv no pab cov engineers tsim kev txhim khu kev qha thiab ua haujlwm zoo.
