Lub hydrodynamic bearing yog ib chav tsev engineering uas lub ntsiab load poob rau ntawm ib txheej nyias ntawm insulating flushing kua txhaj rau hauv cov qauv siv lub lubricated ncej. Feem ntau cov khoom hu ua hydraulic.
Niaj hnub nimno hydrodynamic bearings yog siv nyob rau hauv ntau yam precision mechanisms, tshwj xeeb tshaj yog thaum cov pa rau cov menyuam los yog pob ntau yam tsis tau raws li qhov yuav tsum tau siv rau lawv los xyuas kom meej lub lag luam ntawm ib tug neeg units los yog cov qauv.
Piv txwv li, kev siv cov ntsiab lus hydraulic tso cai rau kev vibration tsawg, qis suab nrov, thaum cov cuab yeej siv tau lub neej ntev. Xws li hom bearings nyob rau hauv cov txheej txheem ntawm kev txhim kho ntxiv thiab kev tsim kho tau dhau los ua kev sib tw, txij li tus nqi ntawm lawv cov khoom tau hloov tas li.poob.
Tsis zoo li cov khoom siv hydrostatic, hydrodynamic bearing muaj lub hauv paus ntsiab lus sib txawv me ntsis ntawm kev ua haujlwm. Yog hais tias nyob rau hauv thawj rooj plaub, lub siab ua hauj lwm ntawm cov kua yog tsim los ntawm ib tug tshwj xeeb lub twj tso kua mis, ces nyob rau hauv lub xeem rooj plaub, nws tus kheej-lubrication yog ua thaum lub ua hauj lwm ncej rotates. Nws yuav tsum tau muab sau tseg hais tias tus kheej-lubrication nyhuv nws tus kheej tshwm sim tsuas yog thaum tej yam ncej rotation speeds mus txog, uas yog qhia nyob rau hauv cov khoom passport.
Txwv tsis pub, lub thickness ntawm cov roj nplua nyeem nyob rau hauv lub ncej yuav tsis txaus, uas yuav ua rau muaj kev sib txhuam quab yuam, thiab nws thiaj li ua rau ntxov ntxov hnav ntawm lub mechanism. Yog li, txhawm rau zam cov xwm txheej no, uas feem ntau tshwm sim, piv txwv li, thaum pib thiab nres lub cuab yeej, nws ua rau kev txiav txim siab siv lub twj tso kua mis tshwj xeeb uas yuav siv rau hauv cov lus piav qhia.
Cov kabmob hydrodynamic muaj ntau qhov zoo. Ua ntej, cov khoom lag luam txhim khu kev qha thiab yooj yim hauv kev tsim.
Feem ntau hauv lawv lub cuab yeej lawv muaj lub nplhaib sab hauv thiab sab nraud nrog cov duab toroidal, ntawm cov pob qij txha ntawm cov khoom lawv muaj hermetic seals. Ua tsaug rau nws cov qauv tsim, cov kabmob hydrodynamic tsis tshua muaj (lossis tsawg) cov nqi khiav haujlwm. Lub tshuab yog tus yam ntxwv los ntawm kev ua haujlwm ntev.
Hauv kev tsim cov khoom lag luam, qhov yuav tsum tau ua rau qib ntawm qhov tseeb yog qhov qis dua hauv kev tsim cov pob lossis cov menyuam hom. Lub suab nrov ntawm cov khoom siv hydraulic yog qis dua lub suablos ntawm dov bearings. Cov khoom tsim kev vibration tsawg heev. Vim cov qauv tsim, lawv muaj peev xwm ua kom muaj zog.
Qhov tsis zoo ntawm cov khoom suav nrog lawv qhov kev nkag siab siab rau qhov tsis raug uas tshwm sim hauv kev tsim cov ncej. Tsis tas li ntawd, lawv muaj lub zog loj heev.
Hydrodynamic bearings tau pom daim ntawv thov hauv cov khoom siv hauv computer. Nrog lawv cov kev pab, lub hard drive ua haujlwm, nrog rau cov kiv cua txias ntawm chav tsev. Tsis tas li ntawd, lawv tau siv nyob rau hauv nuclear reactors, lawv lub zog lub ntsiab ntawm metalworking tshuab.
