Cov yam ntxwv ntawm cov bolts feem ntau yog tshwm sim hauv lawv cov khoom siv hauv paus, lub taub hau zoo, hom xov, thiab cov qauv tsim tshwj xeeb kom ua tau raws li qhov xav tau ntawm kev sib txuas hauv kev ua haujlwm sib txawv.
Lub ntsia liaj qhov rooj yog ib tug fastener uas muaj lub taub hau thiab ib tug threaded shank (lub tog raj kheej nrog lwm threads). Nws yuav tsum tau siv nrog cov txiv ntoo kom ua tiav qhov kev sib txuas ntawm ob qhov chaw nrog los ntawm qhov. Nws lub luag haujlwm tseem ceeb yog tsim kom muaj axial locking quab yuam los ntawm kev sib hloov kom ruaj khov kho cov khoom.
Cov yam ntxwv tseem ceeb ntawm cov qauv muaj xws li:
Ntau Hom Lub Taub Hau: Cov duab taub hau feem ntau suav nrog hexagonal, puag ncig, square, thiab countersunk taub hau. Hexagonal taub hau bolts yog siv dav tshaj plaws, raws li lawv yooj yim rau zawm nrog ib tug ciaj ntswj los yog lub qhov (socket). Countersunk taub hau bolts yog siv nyob rau hauv cov xwm txheej uas yuav tsum tau ib tug tiaj tus nto tom qab kev twb kev txuas thiab yuav muab tag nrho embedded rau hauv ib feem.
Threaded Shank: Lub shank yog machined nrog txheem threads, muab faib ua ntxhib thiab zoo threads. Cov xov zoo muaj kev tiv thaiv zoo dua -loosing kev ua tau zoo thiab kev sib txuas siab dua, tsim nyog rau kev co ib puag ncig; ntxhib threads yog cov kev xaiv ib txwm muaj thiab muaj zog versatility.
Cov Qib Kev Ua Tau Zoo: Bolts tau muab faib ua ntau qib raws li lub zog (xws li 3.6, 4.8, 8.8, 10.9, 12.9). Qib 8.8 thiab siab dua yog siab - lub zog bolts, feem ntau yog siv hauv kev sib txuas tseem ceeb hauv cov qauv hlau. Lawv feem ntau yog ua los ntawm qis- carbon alloy steel thiab tau txais kev kho cua sov.
Kev Tiv Thaiv Tshwj Xeeb-Losing Structures: Txhawm rau kom tsis txhob xoob, qee lub bolts yog tsim los nrog qhov nyob hauv lub taub hau lossis lub shank, tso cai rau kev ntsuas qhov ntsuas ntawm cov hlau lossis cotter pins. Cov no feem ntau siv hauv aerospace lossis siab - cov khoom siv vibration.
Modular thiab Integrated Designs: Piv txwv li, hexagonal bolts integrates bolt, flat washer, thiab spring washer. Qhov no ua ntej- cov qauv sib dhos txhim kho kev sib dhos ua haujlwm thiab txhim kho kev tiv thaiv -loosing kev ua tau zoo.
