Thaum peb yuav Chav Kawm 8.8 bolts, peb feem ntau yuav tsum nkag siab txog lawv cov khoom siv thiab qib zog kom ntseeg tau tias kev siv nyab xeeb. Niaj hnub no, peb yuav saib cov khoom thiab lub zog ntawm 8.8 bolts rau koj siv.
8.8 bolt khoom: Qib kev ua tau zoo ntawm cov ntsia hlau muaj zog yog hu ua 8.8, thiab tom qab kev kho cua sov, cov khoom tuaj yeem ua tau raws li cov hauv qab no: 1. Nominal tensile zog ntawm 640MPa; 2. Qhov sib piv khoov yog 0.8; 3. Nominal yield zog ntawm 640 × 0.8=800MPa; 4. Chav kawm 8.8 hex bolt cov ntaub ntawv suav nrog 1035ACR (hauv qab M10), 1040ACR (saum M12), CH38F, 1045ACR, 1039, 10B21, 10B33 thiab 10B38; 5. Chav kawm 8.8 hex bolt cov ntaub ntawv suav nrog CH38F, 1039, 10B21(M10-M12), 10B33(M14) thiab 10B38(M12-M24).
8.8 bolt lub zog: 8.8 ntsia liaj qhov rooj lub zog hais txog cov kev nyuaj siab ntawm cov ntsia liaj qhov rooj ntawm 8.8GPa thiab 10.9Gpa, nominal tensile lub zog ntawm 800N / MM2, nominal yield zog ntawm 640N / MM2. Chav kawm 8.8 hex ntsia liaj qhov rooj xaiv cov khoom yog tib yam li saum toj no, thiab cov khoom siv hex ntsia liaj qhov rooj kuj zoo ib yam li saum toj no. Feem ntau, qib kev ua tau zoo ntawm bolts yog tus qauv thoob ntiaj teb, thiab cov bolts nrog tib qib, tsis hais qhov txawv ntawm cov khoom thiab keeb kwm, lawv cov kev ua tau zoo ib yam. Yog li ntawd, tus tsim tsuas yog yuav tsum tau xaiv cov qib kev ua tau zoo. Cov chav kawm muaj zog feem ntau yog qhia raws li chav kawm tensile lub zog thiab cov chav kawm kev nyuaj siab ntawm lub bolt, xws li chav kawm 8.8 thiab 10.9. Feem ntau, qib kev ua tau zoo thiab qib zog ntawm bolts tseem ceeb heev rau peb yuav thiab siv bolts. Tshwj xeeb, peb yuav tsum nkag siab txog cov khoom siv, lub zog tensile nominal, lub zog nominal yield thiab lub zog qib ntawm 8.8 bolts, txhawm rau txiav txim siab zoo thaum yuav khoom.
