Kev Taw Qhia Txog Cov Khoom Txuas-1

Cov khoom siv fasteners yog ib hom khoom siv kho tshuab siv los khi thiab txuas ntau yam tshuab, khoom siv,tsheb, nkoj, txoj kev tsheb ciav hlau, choj, tsev, cov qauv, cov cuab yeej, cov twj paj nruag, thiab cov khoom siv. Lawv yog cov yam ntxwv los ntawm ntau qhov ntau thiab tsawg thiab cov lus qhia, ntau yam kev ua tau zoo thiab kev siv, thiab qib siab ntawm kev ua kom raug, kev ua kom tiav, thiab kev dav dav. Yog li ntawd, qee tus neeg xa mus rau ib chav kawm ntawm cov khoom siv txuas uas twb muaj cov qauv hauv tebchaws ua cov khoom siv txuas txheem, lossis tsuas yog cov khoom txheem. Cov khoom siv txuas yog cov khoom siv kho tshuab siv dav tshaj plaws. Tuam Tshoj cov khoom siv txuas raug xa tawm ntau heev mus rau cov tebchaws thoob ntiaj teb, thiab cov khoom siv txuas los ntawm ntau lub tebchaws kuj tseem ntws mus rau hauv kev lag luam Suav. Raws li ib qho ntawm cov khoom lag luam nrog cov khoom xa tawm thiab xa tawm loj hauv Suav teb, kev paub txog cov qauv thoob ntiaj teb rau cov khoom siv txuas yog qhov tseem ceeb heev thiab tseem ceeb rau kev txhawb nqa cov tuam txhab txuas Suav kom mus thoob ntiaj teb, thiab txhawb kev koom tes ntawm cov tuam txhab txuas hauv kev koom tes thoob ntiaj teb thiab kev sib tw.
Kev txhais ntawm xov
1. Ib txoj xov yog ib daim duab uas muaj ib lub helix sib npaug zos tawm ntawm qhov seem ntawm sab nraud lossis sab hauv ntawm ib qho khoom khov.

2. Kev faib tawm xov
Raws li lawv cov yam ntxwv ntawm cov qauv thiab kev siv, lawv tuaj yeem muab faib ua peb pawg:

Cov xov ib txwm muaj: nrog cov hniav peb ceg, siv rau kev sib txuas lossis khi cov khoom. Cov xov ib txwm muaj faib ua cov xov ntxhib thiab cov xov me raws li qhov sib txawv, thiab lub zog sib txuas ntawm cov xov me me yog siab dua.

Cov xov kis tau: nrog cov duab trapezoidal, rectangular, sawtooth, thiab triangular hniav, thiab lwm yam.

Cov xov kaw: siv rau kev sib txuas, feem ntau yog cov yeeb nkab xov, cov xov tapered, thiab cov yeeb nkab xov tapered.

Yog xav nkag siab txog cov khoom siv hauv tsheb, thov saib cov qauv tsheb "Automotive Standard Parts Product Numbering Rules" (QC/T 326-2013). Qhov no xaus cov kev paub thiabkev sib qhia cov ntsiab lus , tag kis yuav muaj ntau cov ntaub ntawv hais txog cov khoom siv txuas.
