Kev tsom xam cov kev tshuaj ntsuam ntawm lub tensile kev ua haujlwm ntawm high-zog bolts

Peb lub tuam txhab Jinrui muaj cov lus qhia: "Me me li lub ntsia hlau, kev nyab xeeb yog qhov tseem ceeb." Hauv kev siv cov ntawv thov, qhov no yog qhov tseeb ntawm - ib lub pob muag me me ua lub luag haujlwm tsis tseem ceeb. Tshwj xeeb tshaj yog nyob rau hauv kev teeb tsa thiab kev sivHigh-lub zog bolts, nruj yuav tsum tau tsim nyog raug tsim tawm ntawm lawv lub zog tensile. Txhawm rau ntsuas cov qib kev ua tau zoo ntawm cov khoom siv rau cov neeg siv tshuab xws li kev sib tw hauv lub ntiaj teb zoo li Gb / T 3098.1), ntau dua suav nrog kev sib tshooj ntawm cov nqi hla los ntawm tus nqi tsim. Cov ntsuas ntsuas ntsuas yuav tsum muab piv nrog cov qib kev kawm qib kev kawm tau teev nyob rau hauv cov qauv kom paub meej tias kev ua raws. Thaum kho cov cuab yeej loj, high-lub zog bolts yuav tsum tau kos npe rau lub hauv paus loj heev tsim los ntawm cov tshuab hnyav tsim los ntawm kev ua haujlwm hnyav thaum ua haujlwm tsis yog. Ua ntej kev teeb tsa, xws li suab, loj txoj kab uas yog qhov kev sib txuas ntawm txoj kev sib txuas ntawm cov qauv Tsoos Kev Loj-Zog Dej-Nres Bolts Bolts Kev Txuas Txuas Tus Qauv Ib zaug ntxiv, yog li qhov tseeb ntawm txoj kev teeb tsa txoj hauj lwm yuav tsum tau lees tias ua ntej.

Hauv kev lag luam nrawm nrawm, ntau tshaj 90% ntawm xov yog txoj cai xov (nruj los ntawm Moos lub sijhawm sib hloov), cov qauv xov uas siv thoob ntiaj teb. Sab laug-tes xov yog nruj los ntawm kev sib hloov countercermet. Muab hais tias feem ntau cov neeg siv yog sab xis, high-zog bolts feem ntau tsim nrog txoj cai xov. Rau cov ntawv thov tshwj xeeb,Ob-kawg boltsTej zaum yuav muaj kev tsim qauv sib xyaw (ib qho kawg sab xis, ib qho kawg sab laug-tes). Los ntawm kev hloov ntu nruab nrab hauv ib qho kev taw qhia, ob qho kawg tuaj yeem xauv ib txhij, ua tiav cov nrawm nrawm. This "thread rotation direction matching motion direction" anti-loosening design is typified in the left pedal of a bicycle – the left pedal uses a left-hand thread, which tightens further as the pedal is pushed rightward, preventing loosening due to vibrations and demonstrating the practicality and scientificity of mechanical design.

Kev kho cua sov yog ib qho txheej txheem tseem ceeb hauv kev tsim cov high-zog bolts. Txij li high-zog kub cov ntaub ntawv (xws li cov hlau roj carbon hlau thiab cov khoom siv sib xyaw ua ntej, muaj cov khoom siv nyoos, txhim kho kev sib xyaw thiab txo cov khoom siv. Tom qab sib sau, cov txheej txheem queming thiab kev kho cua sov "yog siv los txhim kho cov khoom siv tshuab hluav taws xob (kom lub zog, kom lub zog) rau cov qauv tsim nyog. Qhov zoo ntawm kev kho cua sov ncaj qha rau kev txiav txim siab qhov kawg ua tau zoo ntawm covpaj, Xav kom nruj kev tswj hwm cov txheej txheem tsis xws li kub kub, tuav lub sijhawm, thiab txias nruab nrab. Txawm hais tias qhov kev ua haujlwm yuav zoo li txhua tus neeg ua haujlwm yuav tsum nkag siab txog lawv txoj kev ua haujlwm ntawm kev kho cua sov (piv txwv li kev ua tau zoo vim kub thiab tsis txaus. Raws li bolts tuaj yeem hloov qhov ntev vim yog cov khoom siv hluav taws xob thiab cov kev ua haujlwm ntawm rocks, thiab cov neeg ua haujlwm sib tw ua haujlwm nyob rau hauv lub sijhawm ntsuas kub

Kev kho kom sov-kho cov zog feem ntau muaj qhov tsaus grey grey, ua rau lawv muaj kev sib xyaw sib txawv thaum cov khoom lag luam sib txawv thaum cov khoom lag luam. Yog li, kev kho cua sov kom muaj kev faib tawm nrog cov ntawv qhia ywj pheej los tiv thaiv kev pheej hmoo sib xyaw thiab cov kev pheej hmoo zoo los ntawm cov cuab yeej xaus.

Carbon Hlau Boltsare classified into performance grades such as 4.8, 8.8, 10.9, and 12.9 based on heat treatment (14.9-grade bolts, made of special alloy steel, are rarely used in industrial applications):

4. {{{}}} Qib: Dog dig bolts ua los ntawm cov hlau roj carbon roj carbon tsawg tsis muaj lub zog kub zog, haum rau cov thauj dav dav.

8. {{8- qib thiab saum toj no: High-lub zog bolts (8. {8- hlau; 10. {}} Cov hlau ua pa roj carbon monoxide.

Noj10.9 cov qib boltsRaws li ib qho piv txwv: lawv nominal tensile lub zog yog ntau dua los yog sib npaug ntawm cov kev ntsuam xyuas tensile kom ua raws li cov qauv. Cov neeg kho tshuab no tsis muaj cov ntsiab lus tseem ceeb rau kev ntsuas cov qauv kev ua haujlwm ntawm cov neeg muaj kev nyab xeeb thiab kev ntseeg tau ntawm cov qauv kev ua haujlwm.
