Ruzivo rwekutanga rwemageji eshinda
Chiyero cheshinda chiyero chinoshandiswa kuona kana shinda ichienderana nemirau. Mathread plug geji anoshandiswa kuyedza shinda dzemukati, uye ma thread ring gauges anoshandiswa kuyedza kunze.
Thread chinhu chakakosha uye chinowanzoshandiswa structural element. Threads anonyanya kushandiswa mukubatana kwemaitiro, kuvhara chisimbiso, kutapurirana, kuverenga uye kutakura mutoro uye zvimwe zviitiko. Kubva kumamiriro ekushandiswa kwese kusvika kune yakanyanya kuoma (tembiricha yakakwira, kudzvanywa kwakanyanya, corrosion yakanyanya), kubva padanho rakaomarara kusvika kune yakanyarara, muchidimbu, ine huwandu hwakawanda hwekushandisa.
1. shindawo zvayo (inozivikanwawo seAmerican thread kana metric thread) M
2. The American standard unified thread zvakare UNC, UNF, UNEF, UN, UNS series
3. Shinda dzepombi dzisina tambo (tambo dzekare dzinonzi cylindrical pipe threads)
4. Trapezoidal thread
5. Dzimwe shinda
NPSM-American Standard Mechanical Connection Yakatwasuka Pipe Thread: Idzi tambo dzemukati nekunze dzinoshandiswa mahara mechanicha yekubatanidza pasina kumanikidzwa kwemukati. Chigadzirwa chine yakatwasuka pombi go-stop ring plug geji yekuongorora.
NPSL - Yakatwasuka Pipe Threads yeAmerican Standard Lock Nuts: Idzi tambo dzemukati nekunze dzinoshandiswa kune mechanic fit e-anti-feed tambo.
NH - American Standard Fire Hydrant Thread: Idzi tambo dzemukati nekunze dzinoshandiswa pamoto hydrants, magadheni emvura hose, makemikari uye elevator, nezvimwe.
NPSH-National Standard Hose Coupling Threads: Idzi tambo dzemukati uye dzekunze dzinoshandiswa kumhepo, mhepo, mvura uye mamwe maratidziro epombi ekubatanidza.
NPSC-American mureza wepombi yekubatanidza neshinda yepombi yakatwasuka: pombi yejojo ine shinda yakafanana neyemukati yakatwasuka pombi shinda. Kana iyo yekunze tapered tambo NPT inoshandiswa pakusangana kwekuisa chisimbiso kurongedza, inosimbiswa neine wrench, uye kazhinji inogona kugadzira yakavharwa kubatana. Inonyanya kushandiswa kune yakaderera-pressure pombi. nzira yemugwagwa.
NPSF-National Standard Oil Dry Seal Thread: Idzi tambo dzemukati dzinoshandiswa kuungana kusina kuvharwa neNPTF tambo dzekunze pazvinhu zvakapfava kana ductile iron castings.
NPSI - American Standard Dry Seal Intermediate Threads: Idzi tambo dzemukati dzinoshandiswa kuunganidza zvinhu zvakaoma kana brittle zvine mapfupi PTF-SAE ekunze shinda, asi anogona zvakare kushandiswa kuzere kureba magungano ane NPTF ekunze shinda.
Taper gauge yemasilinda egasi
Iyo yakakosha taper tambo yemasilinda egasi inoshandiswa pakubatana pakati pemasilinda nemavharuvhu emhando dzakasiyana dzesimbi masilinda (senge okisijeni cylinders, gasi cylinders, acetylene cylinders, nezvimwewo). Kuvimbika kwekukiya uye kuiswa chisimbiso kwetambo dzakabatanidzwa ndicho chinhu chikuru chekuchengetedza kuchengetedzwa mukugadzira uye kushandiswa.

Metric trapezoidal thread Tr
Trapezoidal tambo dzinonyanya kushandiswa mukutapurirana (yekudya uye kusimudza) uye chinzvimbo chekugadzirisa zvishandiso, uye inoshandiswa zvakanyanya muindasitiri yemuchina. Kushivirira kwetambo dzemetric trapezoidal nekuda kwezvikonzero zvakajairwa kunotora iyo yekushivirira sisitimu yemetric yakajairwa shinda, uye hapana yakaparadzana yekushivirira kukosha kune yega paramita senge shinda lead (pitch) uye sub-measurement angle. Naizvozvo, iyi tambo yetrapezoidal haina kufanira tambo dzekutumira dzinenge dzakanyanya zvinodiwa pakufambiswa kwechokwadi. Iyo chaiyo yekutumira trapezoidal tambo inoda kuwedzera kushivirira kwega tambo paramita pahwaro hweiyo general trapezoidal tambo standard.
Trapezoidal tambo dzinogona zvakare kushandiswa kusungirira kubatanidza. ACME shinda uye metric serrated tambo geji iripo
American yekuyedza sisitimu yekusimbisa tambo (UN, UNR, UNJ, M uye MJ)
Nekuda kwekusanzwisisana kwakawanda, dzimwe njodzi uye zvinodiwa zvehupfumi mumunda wekuona shinda, zvakaunza dambudziko rakawanda pakugamuchirwa kwezvigadzirwa zveshinda uye kuviga njodzi dzakawanda dzakavanzwa kumhando yezvigadzirwa zvemichina. Kuitira kudzosera kumashure mamiriro ezvinhu aya, United States yakaita tsvakiridzo yakawanda yehunyanzvi pakuonekwa kweshinda, uye yakapa zano rekusimbisa tambo yekuona system standard (ASME standard) uye kusavimbika kwedata re60º thread gauge kuyerwa (ASME technical report). United States inotungamira nyika mukugadzira tambo uye yekuyedza tekinoroji. Mune ramangwana, dzimwe nyika pasi rose dzichadzidza kubva pane zvakaitika kuUnited States uye vogadzira yavo yenyika tambo yekuyedza masisitimu maitiro ekuvandudza kunaka kwezvigadzirwa zvavo zveshinda. Kana ruzhinji rwevashandi vehunyanzvi munyika yedu vakadzidza uye kugona iyi seti yekuona tambo tekinoroji nekukurumidza, mhando yezvigadzirwa zveshinda munyika yedu inovandudzwa nekukurumidza, uye isu tichabvisa mamiriro ekugadzirwa kweshinda yakaoma. .
Kubva kuAmerican thread yekuongorora system, unogona zvakare kudzidza imwe yepamusoro tambo yekugadzirisa tekinoroji muUnited States. Semuyenzaniso, kushandiswa kwekusiyanisa chiratidzo geji yekuona tekinoroji inogona kuvandudza iko kurongeka kwematurusi emuchina uye maturusi ekucheka, uye kugadzirisa tambo padyo neiyo theoretically chaiyo saizi. Panguva imwecheteyo, hupenyu hwekushandisa huchawedzerwa.
