Cov khoom siv hlau feem ntau suav nrog cov fasteners- xws li bolts, ceev, screws, thiab rivets-nrog rau cov khoom siv kho tshuab, suav nrog cov iav, bearings, thiab springs.
Cov lus hauv qab no muab cov lus piav qhia ntxaws txog cov khoom hlau no:
Fasteners yog cov feem ntau ntawm cov khoom siv hlau, suav nrog cov khoom xws li bolts, txiv ntseej, thiab cov ntsia hlau. Cov fasteners no feem ntau yog siv los txuas ob lossis ntau qhov sib cais ua ke. Bolts feem ntau yog siv ua ke nrog cov txiv ntseej; los ntawm qhov kev txiav txim ntawm kev sib hloov thiab nruj, lawv tsim ib qho kev sib txuas ruaj khov ntawm cov khoom sib koom. Screws, conversely, yog tsav ncaj qha mus rau hauv lub Cheebtsam tau koom, ua hauj lwm rau ob lub zog ntawm kev twb kev txuas thiab fixation.
Mechanical structural parts-xws li iav, bearings, thiab springs-yog cov khoom tseem ceeb hauv cov cuab yeej siv tshuab. Gears tau ua haujlwm los xa cov kev sib hloov thiab lub zog, ua haujlwm tseem ceeb hauv cov tshuab xa hluav taws xob. Bearings muab kev txhawb nqa rau qhov sib hloov, txo kev sib txhuam thiab hnav kom ntseeg tau tias kev ua haujlwm du thiab ua haujlwm zoo ntawm cov tshuab siv tshuab. Springs muaj nuj nqi khaws cia thiab tso tawm lub zog, yog li muab buffering thiab poob siab - muaj peev xwm nqus tau.
Tsis tas li ntawd, cov khoom siv hlau muaj ntau yam ntawm lwm yam, nrog rau cov hlau hlau, cov raj, thiab cov ntawv txheeb. Cov khoom siv no pom kev siv dav hauv kev tsim khoom thiab kev saib xyuas. Piv txwv li, hlau hlau yog siv los tsim cov khoom siv hluav taws xob sib txuas xws li cov xov hlau thiab cables; cov raj hlau yog siv rau kev thauj khoom los yog kev txhawb nqa; thiab cov ntawv hlau yog ua haujlwm nyob rau hauv kev tsim khoom ntawm ntau yam khoom vaj khoom tsev lossis cov ntaub thaiv npog.
Hauv cov ntsiab lus, cov khoom siv hlau muaj ntau yam sib txawv hauv qhov xwm txheej; nyob ntawm qhov tshwj xeeb daim ntawv thov ib puag ncig thiab cov kev xav tau ntawm kev ua haujlwm, ntau hom hlau tuaj yeem raug xaiv kom tau raws li cov kev xav tau tshwj xeeb. Cov khoom siv hlau no tau siv dav hauv ntau qhov chaw, suav nrog kev tsim kho tshuab, tsheb tsim, hluav taws xob, thiab kev tsim kho.
