Qhov sib txawv ntawm cov qauv hlau hluav taws xob bolts thiab cov bolts dog dig

Cov tub ntxhais sib txawv ntawmTxheej txheem steel boltsthiab cov bolts zoo nkauj nyob hauv plaub qhov ntev tseem ceeb:Yuam Kev Kis Hom, Khoom Siv Zog, Kev Siv Txheej Txheem, thiab Daim Ntawv Qhia TxogCov. Tus qauv tsim qauv ntawm ob yog nkaus ntawm lub chaw nyob ib puag ncig load sib txawv -}} cov kabmob coj tau.

Cov qauv txheej txheem hlau feem ntau yog siv rau hauv cov qauv hlau ua haujlwm (xws li kev ua haujlwm ruaj khov thiab kev nyab xeeb ntawm cov qauv, thiab lawv yuav tsum tau tiv thaiv ntev}} lub sij hawm siv zog lossis zoo li qub. Cov Bolts dog dig, ntawm qhov tod tes, muaj cov xwm txheej sib txuas, tsuas yog xav tau kom tau raws li cov kev xav tau yooj yim. Hais txog kev quab yuam sib kis hom, qauv steel bolts hloov chaw thauj mus los ntawmKev sib txhuam quab yuam tsim los ntawm preload, cia siab rau kev sib txhuam ntawm cov ntsia liaj qhov rooj thiab cov khoom sib txuas los tiv thaiv sab nraud. Dog dig bolts, txawm li cas los xij, kis tsheb los ntawmLub zog shear ntawm lub ntsia liaj qhov rooj shank thiab extrusion quab yuam ntawm bolt thiab lub qhov ntsa{{0-} Tseem ceeb "tawm tsam" sab nraud sab nraud ncaj qha, nrog lub thawv tawm ncaj qha, nrog cov qauv hlau hluav taws xob.

Tshwj xeeb, qhov sib txawv ntawm cov txheej txheem steel sib txawv thiab cov hlua khi zoo nkauj tuaj yeem ua kom ntxaws mus rau tsib lub ntsiab lus hauv qab no:

1. Cov khoom siv thiab lub zog

Txheej txheem steel bolts (tshwj xeeb - lub zog txheej txheem hlau bolts) Lawv lub zog kawm qeb 8.8 thiab siab dua (cov qhab nia tseem ceeb tshaj plaws yog qib 10.9 thiab qib 12,9), uas tuaj yeem tiv thaiv cov nra loj tsis yooj yim ua rau muaj kev tsim tawm yooj yim. Bolts dog dig bolts feem ntau yog ua los ntawm cov carbon qauv hlau xws li Qib Siab (Feem Ntau 4.6), tsuas yog xav tau cov kev xav tau yooj yim rau cov khoom lag luam. Lawv feem ntau tau khoov lossis tawg thaum ris ntau dhau nra.

2. Cov qauv thiab qhov loj me

Cov duab tsim qauv ntawm cov qauv hlau qauv tsom rau "txhim kho qhov ruaj ntseg ntawm kev sib kis tau ntawm kev sib kis tau", nrog hom kev sib kis tauhigh - Lub taub hau Hexagon taub hau Boltsthiab-} Lub zog torsional shear bolts: Hexagon taub haumuaj loj dua thoob plaws - nraim qhov ntev thiab thicker lub taub hau, uas tuaj yeem hloov kho kom muaj txiaj ntsig ntau dua los ua kom cov preload ua tau raws li cov cai; Tergional shear bolts yog nruab nrog "telingional shear tw", thiab lub preload yog tswj hwm los ntawm tus Tsov tus tw thaum lub sij hawm zam kev ua haujlwm yuam kev. Cov Bolts dog dig tuaj yeem muaj cov taub hau me me (xws li hexagon hau, hla kev tsim kho tau zoo) thiab cov qauv dav dav. Lawv tsuas yog xav tau yoog raws li cov ciaj ciam ntawm cov ciaj ciam rau kev teeb tsa, tsis xaiv qhov siab- lub zog preload cov kev cai yuav tsum tau.

3. Kev tsim kho txheej txheem

Lub installation ntawm cov qauv hlau steel muaj qhov tsim nyog ua ntej "(ua kom nruj rau cov qauv tsim" (ua kom nruj rau cov qauv tsim "(Zawm" Kev Soj Ntsuam ". Cov cuab yeej tshaj lij xws li Torque cov ciaj ntswj thiab tergional shear ciaj ntsees yuav tsum tau siv los tswj lub preload. Tom qab kev nruj kev nruj, nws yog qhov tsim nyog los tshawb xyuas seb lub Torque tus nqi yog nce mus rau tus qauv lossis seb cov torsional shear Tail yog qhov tseeb li cas sheared tawm. Lub installation ntawm dog dig bolts yog qhov yooj yim me me: tsis tas yuav tsum tau tswj hwm nrog cov ciaj ntseem taus (xws li cov nyom ntawm cov kev txawj txua) tsis muaj kev txawj tsim kev txawj.

4. Daim Ntawv Thov Kev Sau Npe

Txheej txheem steel bolts tau dav siv hauv cov xwm txheej nrog siab rau lub zog steel (piv txwv li cov yees duab steel), thiab cov tub luam loj (piv txwv, kev sib txuas lus tseem ceeb thiab lub zog hluav taws xob hloov cov yees). Lawv yuav tsum tau tiv thaiv ntev -}} kev cuam tshuam sab nraud xws li cua, nag, kev co, thiab qhov ntsuas kub.Dog dig boltsyog tsim nyog rau cov xwm txheej uas tsis muaj cov ntaub thaiv siab {{}}} Cov kabmob yuav tsum muaj, xws li kev sib dhos rooj tog, thiab lub zog yooj yim. Yog tias siv nyob rau hauv high {{2} Luv Cov xwm txheej, lawv ib txwm muaj kev sib txuas vim tsis muaj zog txaus.

5. Rov Ua Dua

Cov txheej txheem hlau bolts feem ntautsis rov siv tau: Lub sijhawm teeb tsa, lawv yuav tsum tau ua kom nruj rau lub preload ze rau cov khoom siv tawm los lub zog, uas yuav ua rau microscopic yas deformation. Rov qab siv dua yuav ua rau tsis ua tiav qhov uas yuav tsum muaj kev ruaj ntseg, cuam tshuam kev nyab xeeb. Dog dig bolts muaj cov khoom plig tsawg thiab tsis ncav cuag thiab siv tau zoo li cov ntawv xav tau thiab tuaj yeem tshawb xyuas seb puas muaj peev xwm tshawb xyuas seb puas muaj peev xwm tshawb xyuas thiab seb puas yog Shank yog khoov).
