Planet gears xa mus rau lub rotating axis uas tsis kho thiab ntsia ntawm lub bracket (xiav) uas yuav tig tau (qhov dub hauv daim duab 1 yog lub plhaub, thiab daj sawv cev rau cov bearings). Ntxiv nrog rau cov iav planetary (ntsuab), ntxiv rau qhov kev sib hloov ntawm lawv cov rotating ncej (BB) zoo li lub iav axis ruaj khov, lawv cov rotating shafts kuj nyob ib ncig ntawm lub axis (AA) ntawm lwm cov iav (AA) nrog lub xiav bracket ( hu ua planetary stand). Tig. Kev sib hloov nyob ib ncig ntawm nws tus kheej axis yog hu ua "tus kheej-rotation", thiab kev sib hloov ntawm lwm lub iav axes yog hu ua "revolving", uas muaj npe tom qab lub ntiaj teb nyob rau hauv lub hnub ci system.
Tus naj npawb ntawm planetary iav mechanisms txawv los ntawm tus naj npawb ntawm planetary iav ntsia rau ntawm lub planetary thav duab, uas tau muab faib ua ib-kab hnub qub kab thiab dual ntiaj chaw.
Piv nrog rau cov iav kis tau tus mob zoo tib yam, planetary iav kis tau tus mob muaj ntau yam zoo. Qhov tseem ceeb tshaj plaws yog qhov kev hloov pauv hluav taws xob tuaj yeem ua tiav thaum dhau lub zog, thiab cov khoom siv nkag thiab cov zis tawm yog nyob ntawm tib kab kab rov tav. Yog li ntawd, planetary iav kis tau tus mob tau dav siv nyob rau hauv ntau yam mechanical kis tau tus mob nyob rau hauv ntau yam mechanical kis tau tus mob, tus nqi loj hlob, thiab iav kis tau tus mob. Tshwj xeeb tshaj yog vim nws muaj cov yam ntxwv ntawm "siab load thiab loj kis tau tus mob", nws yog siv nyob rau hauv loj qhov ntau nyob rau hauv aircraft thiab tsheb (tshwj xeeb tshaj yog hnyav tsheb). [1] Planet gears kuj tau ua lub luag haujlwm zoo hauv kev hloov lub zog ntawm lub cav. Vim hais tias cov yam ntxwv ntawm lub cav ceev torque txawv heev ntawm txoj kev tsav tsheb xav tau, lub zog ntawm lub cav yuav tsum tau muab faib rau cov tsav tsheb, thiab cov yam ntxwv saum toj no ntawm cov iav planetary tuaj yeem siv los hloov. Tsis siv neeg kis tau tus mob nyob rau hauv lub tsheb kuj siv cov yam ntxwv ntawm lub planetary iav kom tau ib tug sib txawv kis tau tus mob piv los ntawm cov txheeb ze kev sib raug zoo ntawm txhua yam ntawm lub clutch thiab lub nres.
Txawm li cas los xij, vim muaj cov qauv nyuaj thiab kev ua haujlwm ntawm cov iav planetary, nws cov teeb meem kev vibration thiab suab nrov kuj tseem ceeb heev. Nws yog feem ntau ua rau tsis ua hauj lwm xws li lub log hniav qaug zog, cov hniav tawg, thiab txawm lub log hniav los yog axis. Transmission efficiency thiab kev pab lub neej.
