Koj puas yog feem ntau troubled nrog sib txawv threads? G3 / 8? 1 / 4NPT? R1 / 8? UNF? KF16? Tom qab ntawd cia kuv qhia ntau hom xov xwm thiab qhia rau koj paub qhov txawv!
Thoob ntiaj teb Metric Xov System: Cov txheej txheem Suav CNS txais hom kab xov no.Thread saum yog tiaj tus, thiab yoojyim rau tshuab dhos, xov hauv qab yog khawm thiaj li txhim khu lub zog ntawm cov xov. Xov kaum sab xis yog 60 °, Specification yog muaj nyob rau hauv Xov Xwm M.Metric yog ob hom: ntxhib xov thiab zoo nplua.Hais li M8 * 1.25 (M yog code, 8: nominal inch, 1.25: thread distance)
Tus Txheej Txheem Tshaj Tawm: Hauv siab thiab hauv qab yog ob qho tib si ncaj nraim, muaj lub dag zog zoo. Lub qhov kawg yog 60 °, kev qhia ua muaj "ntau npaum li cas txhua nti" .Nws yog cais li NC, NF, NEF qhia li 1 / 2-10 NC (1/2: sab nraud): 10: txhua rooj sib tham txhua ntiv; NC: code)
Unified Thread: Edited by America, England, thiab Canada, thiab tam sim no lees paub li ntiv nplhaib xov. Thread kaum sab xis kuj yog 60 °. Kev soj ntsuam pom muaj li cas "ntau npaum li cas txhua txhua nti". Nws tuaj yeem raug muab cais ua UNC, UNF thiab UNEF. Writen li 1 / 2-10UNC (1/2: sab nraud): 10: txhua rooj sib tham txhua ntiv; UNC: chaws)
Ntsia V Xov: Sab saum toj thiab hauv qab ntawm xov yog ob qho ntse, thiab lub zog yog qaug zog, thiab yooj yim kom tawg, thiaj tsis siv ntau. Thread kaum sab xis kuj yog 60 °.
Whitworth Thread: Tus txheej txheem tau txais los ntawm Askiv.Thread kaum sab xis yog 55 °, muaj qhia nyob rau hauv code "W". Sau raws li W1 / 2-10 (1/2: sab nraud): 10: cov xov tooj txhua nti; W: chaws)
Knuckle Thread: Qhia los ntawm German DIN, thiab daim ntawv thov rau noob, roj hmab hoses.Mark code yog "RD"
Yeeb nkab xov: Siv xov los siv tiv thaiv cov qoob loo, feem ntau siv rau cov yeeb nkab ntawm cov pa lossis kua. Feem ntau cov yeeb nkab txhuam yog "PS, NPS" thiab cov hlua yeeb nkab "NPT", thiab degree degree: 1:16, uas yog 3 / 4 ".
Square Xov Xwm: Kev ua tiav kev khiav haujlwm yog siab, qhov thib ob lub xov pob, tab sis nws tsis tuaj yeem hloov kho ntawm cov txiv ntoo, thiab qhov no yog qhov kev tsis pom zoo.Commonly siv rau lwm cov ntsia hlau thiab cranes.
Trapezoidal Thread: hu ua ACME, thiab qhov kev sib txuas lus qis dua qis dua xov xov xwm, tab sis nws muaj peev xwm yuav kho tau los ntawm cov txiv ntseej tom qab hnav. Metric xov kaum sab xis yog 30 °, Ncej xov 29 °, thiab nquag siv rau tsav ntsia hlau ntawm lub tshuab dhos. Sau ua "Tr".
Buttress Thread: hu ua inclined square xov, thiab tsuas yog muaj feem xyuam rau kev sib kis ntawm kev sib kis, xws li Ntsia ntaus hom tshem tawm, xovxwm tshuab, etc.Txawm li "No"
Qhov loj ntawm nti threads, feem ntau yog pom los ntawm "xov tooj ntawm txhua nti", uas yog sib npaug zos rau qhov sib pauj txiaj. Piv txwv, 8 threads txhua nti, uas yog xov xov nrug yog 1/8 ".
Yog xav paub ntxiv, thov tos txais kuv. Tag nrho koj cov lus nug yuav tsum tau txais kev kho mob ua ntej.
