Taw qhia rau Fasteners-1

Fasteners yog ib hom kev siv tshuab siv los txuas thiab txuas ntau lub tshuab, khoom siv,tsheb, nkoj, railways, txuas hniav, cov tsev, cov qauv, cov cuab yeej, cov cuab yeej, thiab cov khoom siv. Lawv yog cov yam ntxwv ntawm ntau qhov ntau thiab tsawg thiab specifications, ntau yam kev ua tau zoo thiab kev siv, thiab qib siab ntawm standardization, serialization, thiab generalization. Yog li ntawd, qee cov neeg xa mus rau ib chav kawm ntawm fasteners uas twb muaj cov qauv hauv tebchaws raws li tus qauv fasteners, lossis tsuas yog raws li cov qauv. Fasteners yog cov khoom siv dav siv ntau tshaj plaws. Tuam Tshoj cov khoom fastener raug xa tawm mus rau ntau lub teb chaws thoob ntiaj teb, thiab cov khoom fastener los ntawm ntau lub teb chaws kuj tseem ntws mus rau hauv Suav lag luam. Raws li ib qho ntawm cov khoom lag luam nrog cov khoom lag luam loj loj hauv Suav teb, kev ua tiav ntawm cov qauv thoob ntiaj teb rau cov fasteners yog cov tswv yim zoo thiab cov tswv yim tseem ceeb rau kev txhawb nqa Suav fastener tuam txhab mus thoob ntiaj teb, thiab txhawb kev koom tes ntawm cov tuam txhab fastener hauv kev koom tes thoob ntiaj teb thiab kev sib tw.
Xov txhais
1. Ib tug xov yog ib tug zoo li ib tug uniform helix protruding nyob rau hauv tus ntoo khaub lig seem ntawm lub sab nrauv los yog sab hauv ntawm ib tug khoom.

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

Ordinary threads: nrog rau cov hniav daim duab peb sab, siv rau kev sib txuas lossis fastening qhov chaw. Ordinary threads tau muab faib ua ntxhib thiab nplua xov raws li lub suab, thiab kev sib txuas lub zog ntawm cov xov zoo yog siab dua.

Transmission threads: nrog trapezoidal, duab plaub, sawtooth, thiab daim duab peb sab hniav, thiab lwm yam.

Sealing threads: siv rau kev sib txuas sib txuas, feem ntau yog cov yeeb nkab threads, tapered threads, thiab tapered yeeb nkab threads.

Yog xav paub ntxiv txog kev nkag siab txog cov qauv tsheb, thov xa mus rau tus qauv tsheb "Automotive Standard Parts Product Numbering Rules" (QC/T 326-2013). Qhov no xaus kev paub niaj hnub no thiabkev sib qhia , tag kis yuav muaj ntaub ntawv ntxiv txog fasteners.
