Specification raumuaj zog boltsyog ib qho tseem ceeb heev hauv kev tsim khoom, kev muag khoom, thiab kev siv cov bolts muaj zog, yog li kev nkag siab txog nws cov kev xav tau zoo heev rau peb. Hauv kab lus hauv qab no, peb yuav qhia qee cov ntsiab lus tseem ceeb ntawm lub zog muaj zog bolt specifications rau cov neeg nyeem ntawv siv.
1, Kev sib txhuam hom high-strength bolt
Raws li Suav cov kev cai, thaum txhim kho kev sib txhuam hom siab-lub zog bolts, yuav tsum tau siv lub pretension force P, P=0.9*0.9*0.9*fu *Ae/1.2. Qhov no txhais tau hais tias thaum lub sij hawm lub installation txheej txheem, nws yog ib qhov tsim nyog los xam qhov yuav tsum tau ua ntej nro raws li cov qauv no thiab xyuas kom meej qhov tseeb daim ntawv thov ntawm pre nro thaum thov bolts. Qhov no yog ib kauj ruam tseem ceeb hauv kev ua kom ntseeg tau qhov zoo ntawm kev sib txuas bolted.
2, Siab bearing high-strength bolt
Tus tsim tus nqi ntawm tensile bearing muaj peev xwm ntawm lub siab bearing high-strength bolts nyob rau hauv peb lub teb chaws tus qauv kuj yog txiav txim raws li 0.8P, tab sis thaum lub sij hawm kev sib cuag nto slip tau tso cai, nws lub xeev kev nyuaj siab yog tib yam li ntawd. ntawm cov bolts zoo tib yam, thiab cov kabmob muaj peev xwm yog lub zog ntawm lub bolts nws tus kheej. Siab bearing high-strength bolts yog nyob rau hauv qhov kawg bearing muaj peev xwm lub xeev qhov twg lubntsia hlauyog raug shear tsis ua hauj lwm los yog qhov phab ntsa compression tsis ua hauj lwm thaum lub shear quab yuam tshaj lub frictional quab yuam. Txawm hais tias lub shear deformation ntawm lub siab bearing muaj zog bolts ntau dua li ntawm kev sib txhuam hom bolts, lawv cov kabmob muaj peev xwm siab dua li ntawm kev sib txhuam hom bolts.
3, Cov kev xav tau ntawm cov qauv thoob ntiaj teb
Raws li DIN cov qauv, kev sib txhuam hom muaj zog bolts tsis tuaj yeem siv rau hauv thaj chaw av qeeg, tab sis yog tsim los ntawm lub zog ntawm cov bolts lawv tus kheej, tsuas yog cov khoom siv thiab cov yam ntxwv kev nyab xeeb raug txo, uas siab dua cov qauv hauv Suav teb.
4, Kev lees txais cov qauv
Qhov kev lees paub tshwj xeeb GB50205 rau lub zog siab bolts nrog hexagonal pob qij txha yuav tsum tau rov kuaj dua ntawm torque coefficient rau loj hexagonal high-strength bolt kev twb kev txuas khub, thiab ib tug retest ntawm pre nro rau torsion shear hom high-strength bolt kev twb kev txuas khub. Tsuas yog tom qab xeem dhau qhov kev xeem lawv tuaj yeem siv tau. Cov batch loj rau kev kuaj xyuas yog 8 tus qauv rau 3000 teeb. Rau kev sib txuas ntawm lub zog loj ntawm tib lub zog thiab txoj kab uas hla tab sis nrog qhov sib txawv ntawm qhov ntev, yog tias nws tsis tuaj yeem lees paub tias lawv yog los ntawm tib pawg, lawv raug suav tias yog cov qauv sib txawv thiab yuav tsum tau kuaj thiab kuaj cais. GB/T3632-2008 Specification rau Twisted ShearSiab zog Boltsthiab GB131-2006 Loj Hexagonal High Strength Bolts qhia tias nyob rau hauv tib lub batch tej yam kev mob, thaum lub ntsia liaj qhov rooj ntev yog ≤ 100mm, qhov sib txawv qhov ntev yuav tsum yog ≤ 15mm; Thaum lub ntsia liaj qhov rooj ntev yog ≥ 100mm thiab qhov sib txawv ntawm qhov ntev yog ≤ 20mm, nws tuaj yeem suav tias yog tib qhov ntev.
Cov ntsiab lus
Cov lus qhia tshwj xeeb rau lub zog muaj zog bolts ua lub luag haujlwm tseem ceeb hauv kev tsim khoom, muag khoom, thiab siv cov bolts muaj zog. Kev sib txhuam hom siab zog bolts yuav tsum tau ua ntej tensioned raws li specifications kom paub meej qhov zoo ntawm cov ntsia liaj qhov rooj kev twb kev txuas. Lub shear deformation ntawm lub siab bearing muaj zog bolts yog ntau dua li ntawm kev sib txhuam hom bolts, tab sis lawv cov kabmob muaj peev xwm siab dua li ntawm kev sib txhuam hom bolts. Cov qauv thoob ntiaj teb muaj cov kev xav tau siab dua rau cov bolts muaj zog. Thaum lub sij hawm lees txais, qhov loj hexagonal high-strength bolt kev twb kev txuas khub yuav tsum tau mus rau ib tug retest ntawm torque coefficient, thaum lub torsion shear hom high-strength bolt kev twb kev txuas khub yuav tsum tau mus rau lub retest pretension, thiab tsuas yog siv tau tom qab dhau. kev xeem.
