Qhov txawv ntawm 4.8 Qib Bolts Thiab 8.8 Qib Bolts

Cov phooj ywg uas xav tau fasteners yuav tsum tau paub txog cov ntsiab lus ntawm 4.8 thiab 8.8. Feem ntau ntawm lawv yuav tsum muaj kev sib cuag me ntsis. Lawv tsuas paub qhov ntawd xwb8.8 lujzoo dua 4.8 bolts thiab kim dua 4.8 bolts, tab sis tej zaum lawv tsis paub tias qhov twg yog qhov zoo tiag tiag thiab kim npaum li cas. Tsis ntev los no, ib tus neeg siv khoom nug Xiaorui cov lus nug no, yog li siv lub sijhawm no los qhia koj qhov txawv ntawm ob.

Ua ntej tshaj plaws, nws tuaj yeem txiav txim siab tias tus qauv qhov tseem ceeb ntawm 4.8 thiab 8.8 raug cais raws li cov yam ntxwv, thiab cov ntaub ntawv siab dua, qhov ua tau zoo dua.

Zoo li covboltsntawm kev ua lag luam, lawv tuaj yeem muab faib ua peb qib: A, B, thiab C raws li kev tsim khoom. Qib A thiab B yog cov ntsia hlau tshwj xeeb, thiab qib C yog cov ntsia hlau zoo tib yam.

Rau kev sib txuas bolts siv nyob rau hauv cov qauv steel, tshwj tsis yog tias tau teev tseg, lawv feem ntau yog C-qib bolts.

Muaj qhov sib txawv ntawm cov txheej txheem ntawm cov qib sib txawv, thiab cov txheej txheem ua tau zoo feem ntau yog raws li hauv qab no:

① Cov ntsia liaj qhov rooj ntawm A thiab B bolts yog ua los ntawm precision-machined steel los ntawm CNC ua, nrog du nto thiab meej specifications thiab qauv. Cov yam ntxwv qib ntawm cov khoom siv raw thiab cov khoom pabcuam yog 8.8. Nws tsis tshua muaj siv nyob rau hauv kev siv ntau yam, thiab feem ntau yog siv nyob rau hauv ib puag ncig nrog hnyav ib puag ncig thiab siab compressive zog.

② Qib C bolts yog ua los ntawm cov hlau tsis zoo, cov kev qhia tshwj xeeb thiab cov qauv tsis raug txaus, thiab cov yam ntxwv ntawm cov khoom nyoos thiab cov khoom pabcuam yog 4.6 lossis 4.8. Lub deformation yog loj thaum lub sij hawm khoov kev twb kev txuas, tab sis lub installation yog yooj yim thiab raug nqi tsawg. Nws feem ntau yog siv rau tensile kev twb kev txuas los yog ib ntus fastening thaum lub sij hawm installation;

Cov ntsiab lus luv luv yog tias qib 4.8 belongs rau cov bolts zoo tib yam, thaum qib 10.8 thiab 12.9 saum qib 8.8 yog cov bolts tshwj xeeb.

Tau kawg, raws li tus neeg siv khoom, qib siab dua, qhov zoo dua. Raws li kev siv ib puag ncig uas twb muaj lawm, nws yog qhov zoo tshaj los suav cov bolts tsim nyog ua ke nrog tus nqi. Yog tias koj muaj lus nug lossis xav sab laj, txais tos. Xav tias dawb ntxiv peb cov neeg lag luam hauv qab no rau kev sab laj.
