Ib tug tag nrho lub npe rau ib tug metric xov suav nrog cov ntaub ntawv tsis tsuas yog nyob rau hauv xov txoj kab uas hla thiab suab tab sis kuj muaj npe rau cov xov kam rau ua chav kawm . Lub 5g qhia qhov kam rau ua chav kawm rau lub suab diam thiab 6g ua yog qhov kam rau ua chav kawm rau txoj kab uas hla loj.
Kuj nug, dab tsi yog lub ntsiab lus ntawm chav kawm ntawm fits rau threads?
Xov haum yog ib qho kev sib xyaw ua ke ntawm cov nyiaj pub dawb thiab kev ua siab ntev thiab kev ntsuas nruj los yog xoob ntawm lawv. Rau Unified nti ntsia hlau xov muaj rau tus qauv chav kawm haum : 1B, 2B, thiab 3B rau sab hauv xov ; thiab 1A, 2A, thiab 3A rau sab nraud xov.
Ib tug kuj yuav nug, qhov txawv ntawm Class 2a thiab 3a threads yog dab tsi? Chav kawm 1A yog cov khoom lag luam xoob haum rau kev sib dhos yooj yim thiab disassembly. Chav Kawm 2A yog nruab nrab haum. Chav Kawm 3A yog ib tug nruj haum siv qhov twg kaw haum nruab nrab yuav tsum tau mating qhov chaw.
Xav txog qhov no, G thiab H yog dab tsi hauv xov?
" G "xaiv Ground Xov . " H "Raws li lub suab txoj kab uas hla yog nyob rau sab siab ntawm qhov yooj yim. Ob tsab ntawv no (GH) yog ua raws li tus lej qhia txog Kev Ua Siab ntev ntawm Pitch diameter oversize.
Dab tsi yog qhov txawv ntawm 2a thiab 2b xov?
Chav Kawm 1A, 2 A thiab 3A siv rau sab nraud xov tsuas yog, thiab Chav Kawm 1B, 2B thiab 3B siv rau sab hauv xov nkaus xwb. Chav Kawm 1A thiab 1B Unified xov yog npaj rau kev tua phom thiab lwm yam kev siv tshwj xeeb. A 3/8 "-16 UNC 2B txhais tau tias yog 3/8 "inch Unified coarse pitch 2B chav kawm ntawm haum inch ntsia hlau xov.
