Hauv thaj chaw ntawm kev sib kis tshuab,cov txheej txheem iav planetaryyeej ib txwm tuav txoj haujlwm tseem ceeb vim lawv txoj kev tsim qauv tshwj xeeb. Ntau tus neeg txoj kev nkag siab txog cov iav planetary tsuas yog txwv rau lawv txoj haujlwm yooj yim ntawm "qeeb thiab nce torque," tsis quav ntsej txog lawv lub peev xwm nce ceev sib npaug. Qhov tseeb, los ntawm kev teeb tsa cov qauv tsim nyog thiab kev tsim qauv parameter, cov iav planetary tsis tsuas yog ua tiav qhov nce ceev tab sis kuj khaws cia ntau qhov zoo ntawm kev ua tau zoo thaum lub sijhawm nce ceev, ua qhov kev daws teeb meem xa hluav taws xob tseem ceeb hauv kev tsim khoom lag luam, kev thauj mus los, thiab lwm yam.
Lub laj thawj tseem ceeb uas ua rau cov iav planetary nce ceev yog nyob rau hauv lawv cov qauv sib koom ua ke ntawm "lub hnub iav - lub ntiaj teb iav - lub nplhaib iav." Thaum lub nplhaib iav raug kho thiab lub hnub iav yog lub iav tsav, lub ntiaj teb carrier dhau los ua lub iav tsav. Lub sijhawm no, qhov sib piv kis yuav tsawg dua 1, txhais tau tias lub iav tsav tig sai dua li lub iav tsav, yog li ua tiav qhov nce ceev. Piv txwv li, yog tias lub hnub iav muaj 20 hniav thiab lub nplhaib iav muaj 60 hniav, raws li cov qauv piv txwv kis ntawm lub ntiaj teb iav, lub ntiaj teb carrier qhov kev sib hloov ceev yuav yog ob npaug ntawm lub hnub iav. Qhov kev nce ceev no nyuaj rau cov iav cylindrical ib txwm ua tiav. Qhov tseem ceeb dua, cov txheej txheem nce ceev ntawm cov iav planetary tsis yog kev sib sau ua ke yooj yim ntawm kev sib hloov ceev, tab sis yog kev sib kis fais fab du dua los ntawm kev faib sib npaug ntawm ntau lub ntiaj teb iav, zam kev cuam tshuam thiab kev co ntawm ib lub iav kis.
Cov qauv me me yog qhov zoo ntawm cov kev siv planetary iav ceev kom nce. Piv rau cov txheej txheem sib luag-shaft iav ceev kom nce, cov txheej txheem planetary iav siv cov qauv coaxial, nrog txhua lub iav tig ib ncig ntawm lub hnub iav. Rau tib lub zog kis, nws qhov ntim tsuas yog 1/3 txog 1/2 ntawm cov txheej txheem iav ib txwm muaj, thiab nws qhov hnyav kuj txo qis heev. Cov qauv me me no tso cai rau nws hloov kho rau cov ntawv thov uas muaj qhov chaw txwv, xws li cov txheej txheem kis rau cov cav dav hlau thiab cov modules nce ceev fais fab rau cov cuab yeej precision. Hauv UAV fais fab systems, cov txheej txheem planetary iav ceev kom nce tuaj yeem hloov qhov kev sib hloov qis ntawm lub cev muaj zog mus rau qhov kev sib hloov ceev ntawm lub propeller hauv qhov chaw fuselage txwv, thaum ua kom lub fuselage sib dua thiab txhim kho kev ua haujlwm ntev ntawm kev ya dav hlau.
Kev muaj peev xwm xa khoom thiab faib khoom zoo ua rau cov iav planetary ua haujlwm sai dua. Vim tias cov iav planetary sib txuas ua ke nrog lub hnub iav thiab lub nplhaib iav, muaj ntau qhov chaw sib cuag, ua rau muaj kev thauj khoom me dua rau ib cheeb tsam. Qhov no tsis yog tsuas yog txo qhov tshwm sim ntawm kev hnav xwb tab sis kuj txhim kho kev ua haujlwm ntawm kev xa khoom, feem ntau ncav cuag 95% -98%. Hauv cov tshuab tsav tsheb ntawm cov tsheb fais fab tshiab, cov txheej txheem ua kom ceev ntawm lub iav planetary hloov cov zis qis-ceev, siab-torque ntawm lub cev muaj zog mus rau hauv lub zog ceev ceev uas lub log xav tau. Qhov kev xa hluav taws xob zoo no, thaum faib cov khoom thauj thaum tsav tsheb, ua rau lub neej ua haujlwm ntawm lub kaw lus xa khoom ntev dua. Ntxiv mus, cov iav planetary tuaj yeem ua tiav ntau theem ceev nce los ntawm ntau lub iav planetary sib xyaw ua ke, ua tau raws li qhov xav tau ceev ceev ntawm ntau qhov xwm txheej.
Lub luag haujlwm ua kom ceev ntawm cov iav planetary kuj muaj kev ruaj khov zoo heev thiab kev nthuav dav. Lawv cov qauv tsim symmetrical tshem tawm cov zog radial tsim thaum lub sijhawm kis, txo cov ncej khoov deformation, ua rau kev ua haujlwm du thiab suab nrov qis dua. Hauv kev sib koom ua ke ntawm cov neeg hlau lag luam, cov txheej txheem ua kom ceev ntawm lub ntiaj teb iav tuaj yeem ua kom lub cev muaj zog ceev mus rau qhov ceev uas xav tau rau kev txav mus los ntawm cov neeg hlau, ua kom muaj kev sib koom ua ke du thiab raug. Tib lub sijhawm, los ntawm kev hloov lub hnub iav lossis lub nplhaib iav nrog cov suav hniav sib txawv, qhov sib piv ceev tuaj yeem hloov kho tau yooj yim kom haum rau ntau yam kev xav tau ua haujlwm yam tsis tau tsim dua tshiab tag nrho cov qauv kis, txo cov nqi thov.
Txij li kev qeeb qeeb mus rau kev nce ceev, cov txheej txheem iav planetary, nrog lawv cov txiaj ntsig zoo ntawm cov qauv, tawg los ntawm cov kev txwv ntawm cov iav kis tau tus mob ib txwm muaj. Hauv cov teb kev lag luam niaj hnub uas nrhiav kev sib kis zoo, me me, thiab ruaj khov, cov iav planetary ua lub luag haujlwm tseem ceeb hauv kev nce ceev, tshwm sim txhua qhov chaw los ntawm kev tsav dav hlau mus rau kev thauj mus los txhua hnub, los ntawm cov cuab yeej precision mus rau cov tshuab hnyav. Nrog kev hloov kho thev naus laus zis tas mus li, cov txheej txheem iav planetary yuav ua kom zoo dua qhov kev ua tau zoo ntawm kev nce ceev, muab kev txhawb nqa lub zog muaj zog rau kev txhim kho ntawm ntau yam kev lag luam thiab dhau los ua "txhua tus neeg" hauv kev sib kis tshuab.
