Screw threads tuaj yeem pom nyob rau hauv ntau yam khoom siv tshuab. Lawv muaj ntau yam kev siv. Muaj ntau yam khoom muaj rau lawv. Lawv tuaj yeem siv rau fastening. Screws,txiv ntseej-bolts thiab studsmuaj cov ntsia hlau threads yog siv los kho ib ntus rau ib ntus. Lawv yog siv rau kev sib koom ua ke xws li co-axial koom nrog cov pas nrig, thiab cov raj, thiab lwm yam. Lawv tuaj yeem siv rau kev sib kis ntawm cov lus tsa suab thiab lub zog xws li cov hlau lead screws ntawm cov cuab yeej siv tshuab. Tsis tas li ntawd, lawv tuaj yeem siv rau kev xa khoom thiab nyem cov ntaub ntawv. Piv txwv li, lawv nyob rau hauv cov ntsia hlau conveyor, txhaj tshuaj molding tshuab, thiab ntsia hlau twj tso kua mis, thiab lwm yam.
Screw threads tuaj yeem tsim los ntawm ntau txoj kev. Thawj qhov yog casting. Nws tsuas muaj ob peb threads luv luv. Nws muaj qhov tseeb tsawg dua thiab ua tiav tsis zoo. Qhov thib ob yog cov txheej txheem tshem tawm (machining). Nws yog ua tiav los ntawm ntau yam cuab yeej txiav hauv cov cuab yeej sib txawv xws li lathes, milling tshuab, drilling tshuab (nrog tapping txuas) thiab lwm yam. Qhov no yog dav siv rau siab precision thiab tiav. Thiab nws yog ua hauj lwm rau ntau yam ntawm threads thiab ntim ntawm ntau lawm los ntawm daim mus rau loj ntau lawm.
Qhov thib peb yog kev sib sau (dov). Txoj kev no kuj muaj ntau yam ntxwv. Piv txwv li, qhov khoob ntawm cov hlau uas muaj zog zoo li cov hlau yog dov ntawm threaded tuag. Cov xov loj yog kub dov ua raws li kev ua tiav thiab cov xov me me yog ncaj qha txias dov mus rau qhov xav tau tiav. Thiab txias dov attributes ntau zog thiab toughness rau threaded qhov chaw. Txoj kev no yog siv dav rau kev tsim khoom loj ntawm fasteners xws li bolts, screws thiab lwm yam.
Tsis tas li ntawd, kev sib tsoo kuj yog ib txoj hauv kev tseem ceeb rau kev tsim cov ntsia hlau threads. Nws feem ntau yog ua tiav rau kev ua tiav (qhov tseeb thiab qhov chaw) tom qab ua tiav los ntawm kev ua haujlwm lossis kub dov tab sis feem ntau yog ua haujlwm rau cov xov ncaj qha ntawm cov pas nrig. Precision threads ntawm cov tawv tawv los yog nto hardened Cheebtsam yog tiav los yog ncaj qha tsim los ntawm kev sib tsoo nkaus xwb. Nws yog ua hauj lwm rau ntau hom thiab loj ntawm threads thiab ntim ntawm ntau lawm.
Screw threads tuaj yeem muab faib ua ntau hom raws li kev faib tawm sib txawv. Raws li qhov chaw, muaj cov ntsia hlau sab nraud (piv txwv li, ntawm bolts) thiab cov ntsia hlau sab hauv (piv txwv li, hauv cov txiv ntoo). Muaj ncaj (helical) (piv txwv li, bolts, studs), taper (helical), (xws li, nyob rau hauv xyaum chuck), thiab radial (scroll) raws li nyob rau hauv tus kheej centering chuck yog cais raws li configuration. Tsis tas li ntawd, muaj cov xov dav dav (nrog rau qhov dav dav dav), cov yeeb nkab xov thiab cov xov zoo (feem ntau rau cov ntaub ntawv pov thawj) yog muab faib raws li compactness los yog fineness ntawm threads.
Tseem muaj ntau lwm yam kev faib tawm. Txhua yam nyob rau hauv tag nrho, peb tuaj yeem kos qhov xaus tias cov ntsia hlau threads muaj ntau yam kev siv. Lawv cov dej num thiab cov yam ntxwv tsim nyog rau peb txoj kev kawm.
