Threads ton: size. thread ton: GOST

Waxaa si fiican u la og yahay in a ku dhafnaa - mid ka mid ah kuwa ugu badan xidhiidhada fur, jidaynayey si ay u sameeyaan shirka iyo disassembly shaqada iyada oo aan waxyeelo u daacadnimada dhismayaasha iyo mishiino. The salaysan xarunta noocan oo kale ah lagu shubo on dusha laba ama in ka badan wareeg meydadka dunta, kaas oo inta badan ku xiran tahay kala qaybsanyihiin koobin ee hoos lagu sharxay. Dirka threads bixiyo shaxda hoose.

thread ton

goynta Helical on ama in wax a isagoo profile ilig oo ah qaab-xagalka ah oo labaale ah, a - dun ton, dhinacyo qiyaasay in milimitir. Qaabka uu dusha codsiga, thread tani waa cylindrical, laakiin waxa laga yaabaa toobinta.

Arintaan waa kuwa ugu caansan ee isticmaalka, gaar ahaan habka soo socda kulanka:

• boolal;
• barroosinnadii badda;
• boolal;
• hardware;
• silsilado,
• nuts iyo wixii la mid ah.

Dhafnaa, tuntay on salka qaab toobinta, loo yaqaan dunta gabogabaysmo ton. Waxa loo isticmaalaa in meelaha u baahan xiriir quful deg deg ah, ma jirin quwad dheeraad ah oo la joojiyo, garaadlaawayaasha baxsiga jiidaya weheliyaan dhidibka. Waxaa loo adeegsaday in hakadka qalabka iyo xidhiidhada tuubooyin:

• saliid ah;
• saliid ah;
• gaaska,
• biyo;
• hawada.

Waxa kale oo muhiim ah inaad ogaato in toobinta oo thread cylindrical ay leeyihiin profile la mid ah, kaas oo u ogolaanaya in aad u wada dhejiyo. threads ton waxa lagu tilmaamay by size, jihada wareeg, oo soo koobin tallaabo dheeraad ah ayaa ka muuqda sixitaanka.

The dhinacyada threads ton

kala firdhiso The of dhexroor ee dunta in industry ee kala duwan ka 0,25 600 mm, ballaciisu yahay in ka badan 68 thread mm noqon doonaa mid yar oo keliya, halka ka hor inta tirada this - kala duwan. Thread leh garoonka weyn waxaa loo isticmaalaa in xeryahooda hoostiisa sare iyo shoog load. Sidoo kale xiiso leh waa xaqiiqda ah in garoonka dun weyn oo had iyo jeer go'an ee la xiriirta dhexroorka, in la barbardhigo ganaaxa, taas oo kala duwanaan karaan, in si gooni gooni ah iyo wixii intaa tilmaamay in calaamadiyey.

Tusaale ahaan, haddii dukumentiyada farsamo ama sawiro kala goysyada ah ee qaybo ka helay "M16", taas oo macnaheedu yahay in ka yar xarafka M loola jeedaa thread ton. Cabirka of gariiradda dibadda dhexroor - 16 mm iyo garoonka dunta caadiga ah ee ugu weyn - 2 mm, sida ay sheegtay warbixinta ku cad miiska (dunta of Safka labaadna waxaa lagu tilmaamay in bishii Janaayo). Sidaas daraaddeed, thread ton: dhinacyada aasaasiga ah (GOST 24705-2004).

thread garoonka Fine

Sixitaanka muujinaysaa tallaabada ugu yar ka dib markii dhexroor. Waxa ay u muuqataa sida tan: "M16 X 0,5», halkaas oo, sida horay loo yaqaano, M - dun ton. Cabirka of dhexroor dibadda loo siman yahay 16 mm, la size tallaabo - 0.5 mm. Waxa xiiso leh, ka dib markii faraqa u dhexroor 2-mm u dhexeeya garoonka fur u noqonayaa si xooga dareemi, taasoo keentay in isa-soociddiisa. War sidee wax soo saarka dhexroor siman waxay leeyihiin dhowr nooc oo threads garoonka wanaagsan, sida at 16, loo arkaa in mm:

• 1.5 mm,
• 1.0 mm,
• 0.75 mm,
• 0.5mm.

Tusaale ahaan of miiska u ogolaanaya in la fahmo iyo aragga qiimeeyo kala duwan oo threads wanaagsan, marka laga reebo tallaabooyinka ugu muhiimsan hore ka wada hadleen.

qeexan yihiin fursadaha

garoonka badan-dunta lagu muujiyay si gooni gooni ah (in parentheses), iyo tirada entries tilmaamay in ay meel. Halkan sida iyo xuduudaheedu kale oo dheeraad ah ku qeexan calaamadiyey,

• (P1) - meesha P - waa tallaabo ka mid ah 1 mm, iyo gariiradda ah - 3 (tusaale ahaan: 3 M42 × (P1));
• LH - thread tagay (tusaale: M40 x 2LH);
• MK - toobinta thread ton (tusaale: MK24h1,5);
• TUSAALE-M ama GM, halkaas oo G tusinaysaa dun cylindrical ku saleysan insert a silig ama habboon (Tusaale ahaan: Kooxda 6-GM5);
• g, h, H - dulqaad Field waa dulqaad of dhexroor celceliska isku dhafan oo dhexroorka of protrusion ah (tusaale: M12-6g) iyo dulqaadka kala duwan ee dhexroor gudaha iyo dibadda ee labada sixitaanka dulqaad loo qoondeeyey (tusaale: M12-6g / 8 saacadood.)

Ballaca thread

Waxaa jira tilmaamayaasha cad shaxano koobaya wixii muhiim ah in la tixgeliyo marka viewed thread ton - Cabirka dhexroor:

• muuqaalka (D iyo d);
• hoose (D _{1 iyo} d _1);
• Dhexdhexaad (D _{2 iyo} d _2);
• hoose hoose ee niyad-jabka (d _3).

Iyadoo isticmaalka baahsan ee wadajirka ah saraysa muhiimada ay a ku dhafnaa weyn taam helay dhexroor celceliska, iyo in ay dhacdo sinaanta qiimaha, ugu weyn d ₂ handarraabbadeedii iyo ugu yaraan nuts D _2.

warqado Capital D tusinaysaa dhexroorka of threads gudaha, iyo shubo on qaybaha oogada dibadda loo soo warqado yar - d. lambarada ayaa tilmaamaya goobta. Degree of beeraha dulqaad sax tilmaamay characters higgaadda, E, F, G, H, d, e, f, g, h, iyo sida ballaciisu yahay, qiimaha muujinaysa meesha xarfaha.

Saamiga of threads ton oo inch

Marka la barbardhigo dalalka Yurub oo la mid ah, halkaas oo, ka dib markii boqortooyadii Napoleon noqday nidaamka ton baahsan ee dalalka ka mid ah deegaanada hore ee Britain iyo satalayt oo dhan cabbirka ka dhacaan nidaamka Imperial. In nidaamka this, cabbirka of threads oo xiriir la sameeyey in inches.

thread The helical isagoo profile ilig oo ah qaab-xagalka ah oo labaale ah la xagal vertex of 55 digrii a a. (UTS ee heerka Maraykanka iyo Canada -. 60 degrees) waxaa lagu magacaabaa thread inch, dhinacyada ay tahay in inches, iyo garoonka -. In tirada markooda per inch (1 "= 24.5 mm) threads fiiriyey sida yihiin macmalay ee kala duwan 3/16 "in magacaabista muujinaysaa oo keliya dhexroor dibadda.

Cabirka inch iyo threads ton caliper, waxaa lagu cabbiraa, iyo haddii lacala dun ton in uu noqon doono ku filan, in Cabirka inch ka dib markii miiska gaar ah loo isticmaalo. Marka lagu qiyaaso threads isticmaalaya foom caadada, laakiin sidoo kale waxaa jira jid dadka ee lagu qiyaaso tallaabada: haddii, by duubaya xaashi dunta warqad, dhowr jeer si ay ugu rogto iyada oo loo marayo sheyga, imprinted on warqado raad-raac, kaas oo u ogolaanaya in ay sameeyaan taliye cabiraada. Marka loo isticmaalo sida shiraaq qor warqad qaybta ah in line mar dambe uma baahan - waxa ku filan in ay tiriyaan tirada calamado unugyada 2 (1 cm) oo u qaybi 10.

Cabirka godadkii

Qaadashada thread waxaa sabab u ah:

• rogid qabow oo ka mid ah rollers iyo madax;
• jarida chisels, kuwaasoo ah kuwa qora ama shanlooyin;
• jarida dhinto ama qasabadaha,
• shubay saxda ah;
• darane ama machining dheecaan korontada.

Wixii jarida workpiece threads dibadda sameeyay galay qaab cylindrical iyo chamfer, iyo gudaha la qoday wax yar ka yar thread ton lagama maarmaan dalool (size ah), laakiin ka badan ay dhexroor iyo barxadda gudaha. Ka dib markii la qeexo furitaankiisu for tirada thread ton, waxaa lagama maarmaan ah in la tixgeliyo in markii jarida noqtay in wax extrusion qayb danbe ku lug leh dhismaha profile ah ku dhafnaa. Si weyn loo tixgeliyo iyo sifooyinka wax a kaas oo qodista waxaa la sameeyaa, yaraynta size si 0.1 mm layliga.

Cabirka of nuts la thread ton

Nut - mid ka mid ah qaybaha victorious ugu fiiriyey ah, isagoo thread gudaha ah. Waxay ku kala duwan yihiin qaraabo height in dhexroor iyo xoog iyo qaabeynta ay ujeedada looga danleeyahay. Waxaa ugu ballaaran loo isticmaalo waa lowska ama hex-muhiimka ah, in liiska iyaga ka mid ah oo leh calaamad muujinaysa guests:

• GOST 5915-70 - a dhexdhexaad-;
• GOST 15523-70 - sare,
• GOST 22354-77 - kordhay xoog;
• GOST 5916-70 - lowska Low la fasaxa ah,
• GOST 10605-94 - hoos dhexroor thread ka badan 48 mm ah.

Waxaa jira badan oo nuts ah oo gaar ah-ujeeddada, halkan waxaa ka mid ah tusaalooyinka iyo martidooda:

• nooca cap-(hexagonal) - GOST 11860-85;
• waayo, giijisan buuga (the nuts garabka) - GOST 3032-74;
• taaj Welt - GOST 5919-73;
• wareega gool - GOST 11871-88, GOST 10657-80;
• wareega, iyadoo dhamaadka, godad radial - GOST 6393-73;
• waayo, isdabamarinta (il-lowska) - Standard 22355 (DIN580, din 582).

The dhimaya ugu muhiimsan ee xidhiidhada isticmaalaya dun u dhigma iyo thread lowska. Qiimayaasha more caan ah oo leh threads garoonka weyn ku tilmaaman jadwalka hoos ku qoran meesha S - size ee muhiim ah, e - width of lowska, iyo m - sarajooggiisuna.

heerarka

The tirada ugu weyn ee thread ku xiran yihiin GOST 24705-2004, kaas oo wax kabadalaya heerka - ISO 724: 1993 (soocidda caalamiga ah). Tani waxay marti July 1, 2005 waa ekeeyey heer naqdiga ee Ruushka iyo tixgelinaysaa danaha dhaqaalaha dheeraad ah 12 dal, oo horay loogu qayb ka ah Midowga Soofiyeeti, kuwaas oo isaga u codeeyay. Fall ay baaxadda size of threads ton GOST 9150-ujeeddada guud iyo sidoo kale dhexroor iyo tallaabooyinka GOST 8724.

Sida laga soo xigtay caadooyinka dhabta interchangeability GOST hoos ku qoran waxaa loola jeedaa nidaamka heerarka caalamiga ah iyo kuwa wadaniga ah,
