Gear transmissions tau siv los ntawm tib neeg lub sijhawm ntev, txoj kev sib txuas lus ntawm lub zog yog qhov feem ntau hauv kev siv tshuab.
Cov txheej txheem no hloov cov lus tsa suab los ntawm ib tus ncej mus rau lwm qhov, feem ntau nrog kev hloov pauv ntawm zaus ntawm kev hloov pauv ib chav tsev ntawm lub sijhawm. Cov ntsiab lus ntawm kev koom tes thiab cov ntsiab lus ncaj qha ntawm kev sib txuas lus ntawm kev txav yog lub log lossis cov ntsia hlau nrog cov chaw so thiab cov protrusions ntawm cov duab tshwj xeeb txiav rau hauv lawv qhov chaw ua haujlwm.
Ntawm ob lub ntsiab lus sib cuam tshuam hauv kev sib kis, ib qho ntawm txoj kab uas loj dua yog hu ua lub log, thiab qhov thib ob yog hu ua lub iav, txawm hais tias, hauv qhov tseem ceeb, lawv yog ob lub zog.
Txawm tias txoj haujlwm ntawm kev ua kom nrawm ntawm kev sib hloov lossis, hloov pauv, txo nws, yog teem rau hauv lub gearbox, lub log lossis lub iav yog thawj.
Cov khoom siv niaj hnub no ua rau nws muaj peev xwm tsim cov iav muaj peev xwm hloov pauv lub zog mus txog 36 lab watts.
Txoj kev xav tau rau cov txheej txheem sib txawv, yog li ntau yam ntawm cov duab sib dhos yog qhov loj heev. Lub axes ntawm kev sib hloov tuaj yeem ua rau tib lub sijhawm, hla lossis kev sib tshuam, nyob ntawm qhov no, muaj cylindrical, helical,worm los yog bevel iav. Ib tug feature ntawm lub tom kawg yog lub peev xwm rau impart kev sib hloov mus rau ib tug ncej nyob rau ntawm txoj cai kaum rau lub tsav qag. Qhov no yog feem ntau xav tau nyob rau hauv ntau yam ntawm mechanisms, piv txwv li, kev hloov ntawm txhua yam zog los ntawm lub cardan ncej ntawm lub tsheb mus rau lub log tsav yog nqa tawm precisely raws li xws li ib tug kinematic scheme.
Feem ntau, bevel iav muaj ncaj, radially txiav (tangential) cov hniav. Yog hais tias tus tsav tsheb thiab tsav axles tsis sib tshuam, ces xws li ib tug gearbox yog hu ua hypoid. Kev siv cov txheej txheem zoo li no hauv kev tsim lub qag nram qab yog tshwm sim los ntawm kev xav tau ntawm cov neeg tsim khoom kom txo qis tag nrho qhov nruab nrab ntawm lub ntiajteb txawj nqus ntawm lub tsheb kom nws ruaj khov dua.
Ntxiv rau cov iav spur, lwm cov iav siv, piv txwv li, nrog kev txiav kauv.
Ntxiv rau, bevel iav ua rau nws muaj peev xwm sib txuas lus kev sib hloov tsis yog ntawm txoj kab ncaj nraim, tab sis kuj yuav luag txhua lub kaum sab xis, obtuse lossis ntse.
Kev tsim khoom siv thev naus laus zis ntawm bevel iav yog kwv yees li tib yam li cov iav cylindrical, tab sis cov khoom ua haujlwm muaj cov duab zoo nkauj. Nws muaj, raws li nws yog, ntawm ob truncated cones nrog ib tug loj loj puag ntawm tib axis. Lub generatrices ntawm lub cones yog nyob rau ntawm txoj cai kaum. Cov hniav profile tau pom meej meej los ntawm qhov tsis ua haujlwm ntawm lub log bevel, thaum qhov dav ntawm cov hniav txo qis los ntawm qhov chaw mus rau qhov chaw. Cov khoom ntawm kev tsim khoom yog tshwj xeeb steel, resistant rau hnav thiab heevkhov.
Kev txiav profile yog ib txoj kab involute, cov duab no muab cov kev sib hloov zoo tshaj plaws, hnav tsis zoo thiab kev faib tawm siab tshaj plaws ntawm kev ntxhov siab thaum lub sijhawm sib cuag ntawm cov hniav.
Gears nrog qhov sib txawv ntawm qhov profile raws qhov ntev yog qhov nyuaj rau kev tsim khoom, thiab cov tshuab CNC siv los tau lawv.
