"Numeric Code" ntawm Kev Ua Haujlwm Qib
Lub tshuab ntxhua khaub ncaws tiaj tus qib kev ua tau zoo ua nws "daim npav tus kheej," siv cov lej sib xyaw kom pom nws lub zog compressive thiab npaj siv. Cov kev faib qib feem ntau nthuav dav ntawm qhov qis mus rau siab, suav nrog ntau yam kev xav tau-los ntawm cov khoom siv hauv tsev mus rau cov tshuab hnyav. Piv txwv li, cov tshuab ntxhua khaub ncaws qis dua yog tsim nyog rau cov khoom siv niaj hnub tsuas yog me me, qhov siab dua - cov tshuab ntxhua khaub ncaws muaj peev xwm tiv taus cov kev vibration hnyav uas tsim los ntawm cov cav. Cov lej no tsis raug muab tso rau; es, lawv yog cov txiaj ntsig ntawm kev sib xyaw ua ke ntawm cov khoom muaj pes tsawg leeg thiab cov txheej txheem kho cua sov. Qhov zoo siab, rau cov tshuab ntxhua khaub ncaws ntawm tib lub cev loj, qib kev ua haujlwm siab dua sib haum rau cov qauv hlau denser thiab, yog li ntawd, kev ua haujlwm zoo dua rau deformation.
Cov ntaub ntawv zais tom qab cov qib
Flat washers ntawm ntau qib kev ua tau zoo harbor sophisticated designs rooted nyob rau hauv cov ntaub ntawv science. Cov khoom qis dua -qib cov khoom feem ntau siv cov qauv carbon steel, nrog kev ua kom tawv tawv los ntawm kev kho yooj yim quenching. Nruab nrab- qib qib pib koom nrog cov ntsiab lus alloying- xws li manganese thiab chromium- txhawm rau txhawb kev tiv thaiv corrosion. Cov khoom qib siab - qib, hloov pauv, ntiav cov hlau tsis muaj steel lossis cov hlau tshwj xeeb, thiab tej zaum yuav tau ua cov txheej txheem carburization kom ua tiav qhov zoo ntawm qhov tawv. Piv txwv li: ib qho nruab nrab - lub tshuab ntxhua khaub ncaws tuaj yeem tiv taus 200 xuab moos hauv kev ntsuas ntsev tsuag yam tsis muaj xeb, qhov siab - cov khoom qib siab tuaj yeem tiv taus ntev dua 500 teev. Qhov kev sib txawv no ua rau lawv tsim nyog rau ib puag ncig sib txawv- xws li cov chav ua noj ntub dej piv rau cov khoom siv hauv hiav txwv ntug dej hiav txwv, feem.
Yuav ua li cas kom paub cov qhab nia ceev
Thaum xaiv cov ntxhua khaub ncaws tiaj tus, cov qib kev ua tau zoo feem ntau yog stamped rau ntawm cov khoom nto lossis luam tawm ntawm lub ntim. Cov txheej txheem kev txheeb xyuas yog ncaj qha: tus lej ntau dua feem ntau qhia txog kev ua tau zoo dua, txawm tias ib tus yuav tsum tau ua raws li cov kev xav tau tiag tiag rau hauv tus account. Piv txwv li, thaum fastening lub tsheb kauj vab log qag, ib nrab - qib kev ua tau zoo feem ntau yog txaus; Txawm li cas los xij, cov mounting bolts rau lub tsheb cav xav tau siab -qib ntxhua khaub ncaws kom ntseeg tau ntev - lub sijhawm ruaj khov. Interestingly, qee qhov siab -kawg ntxhua khaub ncaws muaj cov ntawv sau ntxiv nrog rau lawv cov lej cim-xws li 'H' rau siab-kub tsis kam lossis 'C' rau cov tshuaj tiv thaiv corrosion- muab cov ntaub ntawv ntxiv uas pab cov neeg siv ntau qhov sib npaug ntawm lub tshuab ntxhua khaub ncaws rau nws cov ntawv thov.
