Noocyada threads loo isticmaalo farsamo

Xardho waa galool florid la garoonka joogto ah u amro on toobinta ama dusha cylindrical. Waa element ugu weyn ee isku xidha laba nooc oo ah qaybood ah, iyo sidoo kale fur iyo baxbaxsan marsho helical. beegyada uu threads aasaasiga ah ee casriga ah qaybood ah lagu qeexay GOST 11708-82: this garoonka thread dhexeeya convolutions ku xeeran, ee dhexroor dibadda iyo gudaha ee element guntinta, xagal vertex ee dunta.

Noocyada threads on qaybood ah u kala qaybsan yihiin:

• qoyska - waxaa laga codsadaa in ay lowska, iyagoo barroosinno darafta, laysku xidho, iyo biibiilaha,
• dibadda - waxaa lagu dhejiyay on the boolal, boolal, boolal, handarraabbadeedii, silsilado.

The noocyada soo socda ee threads on martida u dhigma:

• Ton - profile qaab xagal ah isle (oo mararka qaarkood la yar, dhexdhexaad iyo tallaabooyinka weyn);
• inch - qaab saddex xagal ama trapezoidal;
• toobinta ton - ayaa profile ah saddex xagal,
• wareegsanaa - vertex qiyaas qaab wareeg ah,
• protrusion trapezoidal top - trapezoidal;
• Adkaysta - profile trapezoidal ku dhufo;
• Qaybsan - profile trapezoidal;
• tube toobinta iyo cylindrical (uu leeyahay qaab-xagalka ah oo labaale ah la size inch fekrado (ama ploskosrezannoy) danbow oo berkedihii coil);
• inch toobinta - profile ploskosrezannoy la Cardiff oo ah qaabka xagalka ah.

Weli waxaa jira noocyo qaar ka mid ah threads, sida square ah iyo qaab. Waxay waxaa laga codsadaa in ay lathes qaybood ah, waayo, sawiro shaqsiga. Noocyadaas of threads aadan bixin Heer sare ah ee saxsanaanta, si dhif ah loo isticmaalo. Iyagu ma jiraan guests.

Si aad u taariikhda, codsiga injineernimada ton thread dibadda iyo gudaha ee aasaasiga ah waxaa loo arkaa. In sawiro, waxaa la muujinaysaa warqad caasimadda ah "M" oo tilmaamaysa dhexroor dibadda ee milimitir. noocyada thread biibiile waxaa loo isticmaalaa in lagu xiro tuubooyinka kala duwan. Ay dhexroor magacaaban yahay gudaha dhexroor biibiilaha, ka baxsan taas oo waxaa ku dhafnaa. In sawiro, waxaa la muujinaysaa by a warqad caasimada «G» tilmaan ballaciisu gudaha biibiilaha way ku inches.

The tirada thread ugu muhiimsan ee noocyada dhan yihiin xogta tixraaca. Waxay waxaa laga heli karaa buug-makaanig kasta. xogta tixraaca ee thread ton tilmaamay si faahfaahsan sida ay GOST 9150-81, 8724-81, iyo 24705-81. tirada thread cylindrical biibiile waxaa lagu cayimaa GOST 6357-81.

Mid ka mid ah qaybood wadaagaan thread ton waa bool ah. Waa ul bir ah ku wata madaxii mid ka mid dhamaadka ah. Dhinacyada dhererka ushii codsatay in ay jeexdin ah helical. handarraabbadeedii Ujeeddo - xidhiidhka ka mid ah qaybaha kala duwan ee hababka iyo naqshado by yahay ee nuts. madaxa bool waa lixgeesle u qaabeysan, iyo (qarsoodi ah, qeybtii wareega, baadkiisa, BS, terminal).

The noocyada soo socda ee handarraabbadeedii sidii loogu talo galay:

• Alaabta - waxaa loo isticmaalaa in lagu xiro waxyaabaha soo saaridda alaabta;
• injineernimada - loo isticmaalo in waaxda ganacsiga;
• marashidiisii - loogu talagalay hawlanaa mishiino waaxda beeraha;
• gaadiidka - isticmaalaa in lagu sii labanlaabi biraha kala duwan iyo biraha.
