Waa maxay thread inch

Currently, suuqa qalabka dhismaha waxaa inta badan ku bixiyeen biibiile tirada ku qeexan yihiin in inches. iibsada badan oo aan ku bixin kartaa dareenka waxa si, oo sidaas daraaddeed waxaa suuro gal ah ee tuubooyinka afku la size a in aan isaga waafaqsanaynina, in loo baahan yahay. Sababta tani been in xaqiiqda ah in inch thread (muujinaysaa on dusha biibiile), sida magacaba ka muuqata, waxa lagu qiyaasaa in inches. Sayidka hal inji u dhigmaa 25.4 mm. Qiimaha Tani waxay ka duwan tahay heerarka la aqbalay ee millimeter, taas oo si weyn u adkayn kartaa doorashada ee faahfaahinta loo baahan yahay.

bandhigay inch Thread bixisaa a tirada biibiile cylindrical in inches, halka garoonka of dunta lagu tilmaamayaa ee Joogaba, cutubyo ka (sabab u tahay qiimaha yar).

Maaddaama ay kala soo qiimeeyo millimeter iyo inch, ku dhaqanka uu jiro farqi la taaban karo oo u dhexeeya dhinacyada dunta on biibiile. Tani waa sababta oo heerarka Western farayaan: thread inch tusinaysaa gudaha dhexroor biibiilaha. Waxaa waa in ay tixgeliyaan kala duwanaanshaha u dhexeeya ton oo inch, sidaas darteed loo yaqaan tube.

Tusaale ahaan, on tuubada tilmaamay in size thread inch waa ½. Sidaas darteed, waxaad ka heli biibiile ballaciisu ah sare ee 20,95 mm, halkii la filayo 12.7 mm. Sidaa tube inch lagu helo inuu 33,249 mm waxayna ka kooban yihiin size a si toos ah marinka, oo derbiyadeeda dhumucdiisuna double.

Laga soo bilaabo tusaalahan waxaa cad in isticmaalka dhimaya tani waa dheeraad ah oo ku habboon, tan iyo markii habkaan waa fiican tilmaamay xajmiga, taas oo uu leeyahay thread inch.

Haddaba, marka waxay noqotay sal cad, tag soocidda iyo shaqo ee u dhimaya nabadgelyada this.

Dhululubada ah inch thread on ujeedada iyo nooca shaqada ay u qaybsan yahay:

1. Sii kordhaya thread. Noocaan wuxuu dhaqan ahaan loo gudbiyaa inch iyo thread ton isagoo profile a xagalka ah. Ton waxaa loo isticmaalaa in design ah ee mishiinada iyo unugyada cusub, halka kii labaad waxaa looga baahan yahay wax soo saarka ee kala duwan oo ka mid ah dayactir.
2. thread gaarka ah waxaa ka mid ah hannaanka a of iskeel oo kala duwan ma waafaqsan heerarka.

thread ton oo inta badan la-macmalay la profile a isagoo xagal 60 °. All qiyamka, ama dhexroor dibadda garoonka thread waxaa lagu tilmaamay in milimitir.

At magnitude tallaabo la kala saaro mid ka mid aasaasiga ah iyo 5 nooc oo thread kaabayaal ah (sidoo kale loo yaqaan-gacmeed). Waa in la ogaadaa in thread noocan oo kale ah waxaa loo arkaa inay ka xoog badan ugu wayn (markii dhexroor dibadda ah si buuxda loo siman yahay). Faa'iidada muuqata of threads ganaax kale oo la odhan karaa xagal yar galool u qaadaya iyo, sidaas awgeed, kor u torsion-caabin ah.

thread ee noocan ah waxaa loo isticmaalaa in meelaha godan ugu rartay, iyo sidoo kale xubno ka ah in ku xiran yihiin jolts xoog leh iyo naxdin leh. lowska sixitaanka ayaa sidoo kale thread la mid ah, sida ay u oggolaanaysa in sixitaanka more sax ah.

Intaas waxaa sii dheer, thread inch ordo marka xagal wareeg of 55 °. Xaaladdan oo kale, dhexroor ayaa weli dhigay inches, laakiin garoonka dunta waxaa lagu go'aamiyaa tirada threads per inch. Noocaan waxaa loo isticmaalaa in kala duwan ee kala goysyada xidhnayn for qardarin farsamo ee u dhexeeya qaybaha ku.
