Yintoni ngentambo intshi

Okwangoku, imarike izinto zokwakha zidla wanikela umbhobho ubukhulu zixeliweyo ngo intshi. abathengi abaninzi abakwazi ukuhlawula ingqalelo kuyo, yaye ke ngoko kukho amathuba imibhobho ukufunyanwa kunye ubukhulu leyo engahambelaniyo elifunekayo. Isizathu soku usendleleni yokuba intshi msonto (zibonakaliswe phezu umbhobho kumphezulu), njengoko igama lichaza, ulinganiswa intshi. Kanjalo intshi ilingana 25.4 mm. Eli xabiso yohlukile imilinganiselo eyamkelekileyo millimitha, nto leyo nzima kakhulu ekukhetheni i-iinkcukacha eziyimfuneko.

Thread intshi bonisa inika ubukhulu umbhobho zezindlu e intshi, ngoxa incochoyi kumsonto iboniswe kwi olinganise iiyunithi (ngenxa ixabiso ayo).

Ngenxa divergence silixabisile millimitha kunye intshi, xa kusenziwa kukho umahluko omkhulu phakathi imilinganiselo msonto kwi umbhobho. Oku kungenxa yokuba zemigangatho yemfundo eNtshona uchaze: ngomsonto intshi libhekisela embilwini sangqa kumbhobho. Kufuneka uthathe ingqalelo umahluko phakathi engenayo kunye intshi, benjenjalo ukumemeza ityhubhu.

Umzekelo, kwi ityhubhu lubonise ukuba ubukhulu intshi umsonto yi ½. Ngoko ke, ufumana umbhobho kunye ubudeki ongaphandle 20,95 mm, endaweni kulindeleke 12.7 mm. Ngenxa yoko intshi tube kufumaniseka ukuba 33,249 mm kwaye iquka a ubungakanani ngqo isicatshulwa kunye neendonga ubukhulu kabini.

Kulo mzekelo kucacile ukuba ukusetyenziswa kwale parameter yoxwebhu ingaphezulu, ekubeni le nkqubo kuhle ubonakalise ubungakanani, eye ngomsonto inch.

Ngoku, xa waba ubhalo ecacileyo, hamba uye hlulwa kunye nokunikezelwa yale parameter.

Isilinda intshi intambo malunga nenjongo kunye nohlobo yomsebenzi yahlulwe:

1. Ayanda ngentambo. Olu hlobo ngokwesiko ekubhekiswa intshi nemisonto metric ukuba iprofayile ngunxantathu. Metric isetyenziswa kuyilo oomatshini abatsha kunye neeyunithi, lo gama i-yesibini efunekayo ekuveliseni ezahlukeneyo abaza kuzisebenzisa.
2. Cu ezizodwa iquka ezininzi ezahlukeneyo ngobukhulu hayi ngokuvisisana nemilinganiselo.

ngomsonto Metric badla wenza umfanekiso enehlala engile ° 60. Konke okuxabisekileyo, nokuba okanye zangaphandle ngomsonto kwelizwi ubukhulu ziboniswe iimilimitha.

Kwinyathelo ubukhulu ukwahlula iintlobo omnye zaseprayimari 5 ngemisonto oluncediswayo (ekwabizwa ngokuba nzulu). Kufuneka kuqatshelwe ukuba umsonto loo kuthathwa ukuba longamele (xa ngobubanzi ngokulinganayo ngokupheleleyo elingaphandle) ngobukhulu. Inzuzo elikhangeleka imisonto entle nazo ngokuba engile encinane ngokuziphakamisa kweleli kwaye, ngenxa yoko, ukwanda torsion-ukuxhathisa.

Intambo olu hlobo lisetyenziswa iindawo ezibuhlazarha kakhulu ntli, ngokunjalo izinto zixhomekeke jolts omeleleyo nezothuso. Le uhlengahlengiso nut kwakhona zinento efanayo, njengoko kuvumela ukuba hlengiso ngqo ngakumbi.

Ngaphezu koko, intambo intshi gxada xa ukujikeleza engile ° 55. Kulo mzekelo, i ubukhulu nangoku bunikwa iindawo intshi, kodwa inowuthi umsonto umiselwa inani imisonto-intshi. Olu hlobo isetyenziswa ezahlukeneyo kwamalungu yangaphakathi ye nitrogen ngoomatshini phakathi kwamalungu.
