Hauv kev ua ntawm Precisiontshuabthiabkev tsim khoomtsim, threads ua lub luag haujlwm tseem ceeb hauv kev ua kom cov khoom sib haum xeeb thiab ua haujlwm zoo. Txawm hais tias koj ua haujlwm nrog screws, bolts, lossis lwm yam fasteners, nws yog ib qho tseem ceeb kom nkag siab txog qhov sib txawv ntawm ntau yam xov. Hauv qhov blog no, peb yuav tshawb nrhiav qhov sib txawv ntawm cov xov tooj ntawm sab laug thiab sab xis, ib leeg thiab ob-lead (lossis Dual-Lead) xov, thiab muab kev nkag siab ntau ntxiv rau cov xov xov tshwj xeeb thiab daim ntawv thov.
- Txoj xov sab xis thiab sab laug tes xov
1.1Txoj xov sab xis
Txoj cai threads yog cov xov ntau tshaj plaws siv hauv machining. Lawv yog tsim los kom nruj thaum tig clockwise thiab loosen thaum tig counterclockwise. Qhov no yog tus qauv xov convention thiab feem ntau cov cuab yeej, fasteners thiab cov khoom yog tsim nrog txoj cai threads.
Daim ntawv thov:
- General hom phiaj screws thiab bolts
- Feem ntau cov khoom siv tshuab
- Cov khoom siv niaj hnub xws li jars thiab fwj
1.2Sab laug tes xov
Ntawm qhov tod tes, sab laug-tes threads nruj thaum tig counterclockwise thiab loosen thaum tig clockwise. Cov xov no tsis tshua muaj tab sis qhov tseem ceeb hauv qee cov ntawv thov uas qhov kev hloov pauv ntawm cov khoom siv yuav ua rau txoj hlua sab xis kom xoob.
Daim ntawv thov:
- Qee hom tsheb kauj vab pedals
- Qee qhov chaw tsheb (xws li lub log sab laug)
- Cov tshuab tshwj xeeb feem ntau yog rau kev sib hloov ntawm counterclockwise
1.3 Qhov txawv tseem ceeb
- Kev taw qhia ntawm kev sib hloov: txoj cai-tes threads nruj clockwise; sab laug tes threads zawm counterclockwise.
- Lub hom phiaj: Cov xov sab xis yog tus qauv; sab laug tes threads yog siv rau cov ntawv tshwj xeeb los tiv thaiv kev xoob.
- Tib txoj hlua khi thiab ob txoj hlua hlau
2.1 Ib leeg txhuas xov
Ib leeg txhuas threads muaj ib tug nruam xov uas spirals nyob ib ncig ntawm lub ncej. Qhov no txhais tau hais tias rau txhua lub kiv puag ncig ntawm cov ntsia hlau lossis ntsia liaj qhov rooj, nws nce mus txog qhov deb ntawm qhov sib npaug ntawm cov xov suab.
Feature:
- Yooj yim tsim thiab tsim khoom
- Haum rau cov ntawv thov uas xav tau cov lus tsa suab meej
- Feem ntau siv rau tus qauv ntsia hlau thiab bolts
2.2 Dual lead xov
Dual lead threads muaj ob qho tib si sib luag, yog li lawv nce ntau linearly ib kiv puag ncig. Piv txwv li, yog tias ib lub xov tooj txhuas muaj lub suab ntawm 1 hli, ob lub xov tooj txhuas nrog tib lub suab yuav nce mus txog 2 hli ib kiv puag ncig.
Feature:
- Kev sib dhos sai dua thiab kev sib tsoo vim muaj zog tawm suab
- Zoo tagnrho rau cov ntawv thov uas yuav tsum tau hloov kho sai lossis nquag sib dhos
- Feem ntau siv rau hauv cov ntsia hlau, jacks thiab qee hom fasteners
2.3 Qhov txawv tseem ceeb
- Tus nqi ntawm kev ua ntej ib lub kiv puag ncig: Ib leeg cov hlau lead ua ntej ntawm lawv lub suab; ob zaug txhuas threads ua ntej ntawm ob zaug lawv lub suab.
- Kev Ua Haujlwm Ceev: Dual lead threads tso cai rau kev txav nrawm dua, ua rau nws haum rau cov ntawv thov uas ceev yog qhov tseem ceeb.
- Kev paub ntxiv threading
3.1Suab
Pitch yog qhov kev ncua deb ntawm cov xov uas nyob ib sab thiab ntsuas hauv millimeters (metric) lossis threads ib nti (imperial). Nws yog ib qho tseem ceeb ntawm kev txiav txim siab npaum li cas lub fastener haum thiab ntau npaum li cas nws tuaj yeem tiv taus.
3.2Xov Tolerance
Xov kam rau ua yog qhov tso cai sib txawv ntawm ib txoj xov los ntawm qhov ntsuas qhov ntev. Hauv cov ntawv thov precision, nruj kam rau ua yog qhov tseem ceeb, thaum nyob rau hauv cov xwm txheej tsis tshua muaj teeb meem, looser tolerances tau txais.
3.3Xov Form
lMuaj ntau ntau hom xov, xws li:
- Unified Thread Standard (UTS): Feem ntau hauv Tebchaws Meskas, siv rau cov hom phiaj dav dav.
- Metric threads: dav siv thoob ntiaj teb thiab txhais los ntawm International Organization for Standardization (ISO).
- Trapezoidal xov: siv nyob rau hauv daim ntawv thov kev xa xov hluav taws xob, nws muaj cov duab trapezoidal kom muaj peev xwm thauj khoom zoo dua.
3.4Xov Txheej
Txhawm rau txhim kho kev ua haujlwm thiab tiv thaiv corrosion, xov tuaj yeem coated nrog ntau yam ntaub ntawv xws li zinc, npib tsib xee lossis lwm yam txheej tiv thaiv. Cov coatings no tuaj yeem ua rau kom lub neej thiab kev ntseeg tau ntawm kev sib txuas threaded.
- Hauv kev xaus
Kev nkag siab qhov sib txawv ntawm sab laug tes thiab sab tes xis threads thiab ib leeg-lead thiab ob-lead threads yog qhov tseem ceeb rau HY Metals cov neeg ua haujlwm thiab peb cov neeg siv khoom koom nrog hauv machining thiab kev tsim khoom. Los ntawm kev xaiv cov xov zoo rau koj daim ntawv thov, koj tuaj yeem ua kom muaj kev sib txuas ruaj ntseg, kev sib dhos zoo, thiab kev ua haujlwm zoo. Txawm hais tias koj tab tom tsim cov khoom tshiab lossis tswj cov tshuab uas twb muaj lawm, kev nkag siab ntawm cov xov xov tshwj xeeb yuav muaj txiaj ntsig zoo rau koj qhov kev tsim thiab kev ua haujlwm.
