Imigangatho yei-astm a36 intonga enentambogubungela iiparamitha ezininzi ezifana nedayamitha yegama, ilothe kunye nobude. Xa uyila, kuyimfuneko ukukhetha iinkcukacha ezifanelekileyo ngokweemfuno ezithile zesicelo kunye nomthamo womthwalo.
a193 b7 wonke umsontoi-a449 intonga enedayamitha ephothiweyo:
a449 intonga enentambobanoluhlu olubanzi lweedayamitha ezizigama, kunye neenkcukacha eziqhelekileyoumgangatho wentonga enemisonto yemvelisoziyi 12, 14, 16, 20, 25, 32, 40, 50, 63, 80, 100, 120, njl. Nangona kunjalo, kufuneka kuqatshelwe ukuba uninzi lwabavelisi lunendawo yesitokhwe sedamitha ukusuka kwi-16 ukuya ku-50, kwaye uninzi lwe ezinye iidiameters zikamva, oko kukuthi, ziveliswa ngokwemiyalelo, kwaye ixesha lokuhanjiswa lihlala liphakathi kwe-30 kunye neentsuku ze-60, ezinokuthi zibe ziinyanga ezi-2 ukuya kwezi-2.5 kwiimveliso zaseJapan kunye ne-3 ukuya kwiinyanga ze-4 kwiimveliso zaseYurophu naseMelika. Idayamitha yegama ngokusisiseko ilingana nomthamo womthwalo, oko kukuthi, ubukhulu becala, ubukhulu bomthamo womthwalo. Xa kuyilwa, iikhonsepthi zomthwalo olinganisiweyo oguquguqukayo kunye nomthwalo olinganiselweyo kufuneka zibhekiswe kuwo, apho umthwalo we-axial ojikelezayo ubhekiselele kumthwalo olinganisiweyo we-axial kwisimo esishukumayo, kunye nomthwalo olinganisiweyo we-static ubhekiselele kumthwalo we-axial olinganiselweyo kwimeko ye-static. Ekusetyenzisweni okwenyani, umthwalo olinganisiweyo awungowona mthwalo uphezulu. Umlinganiselo omncinci womthwalo wangempela kumthwalo olinganisiweyo, ixesha elide ubomi bethiyori yesikrufu.
steel stainless steel threaded intonga astm Lead
ekwaziwa ngokuba yipitch, ibhekisa kumgama i-nati ewuhambayo ngokomgca wokujikeleziswa kwesikrufu.steel stainless steel threaded intonga umenzi we-astmIimpawu eziphambili eziqhelekileyo ziquka i-1, 2, 4, 6, 8, 10, 16, 20, 25, 32, 40, njl njl. Iimveliso zamabala amancinci naphakathi ahamba phambili ngokubanzi zi-5 kunye ne-10 kuphela, ngelixa izikhokelo ezinkulu zihlala kwixesha elizayo. Isikhokelo sinxulumene nesantya somgca. Xa isantya segalelo sihlala sihlala, isikhokelo esikhulu, ngokukhawuleza isantya.
Ubude bentonga ye-astm f593
Ubude bei-astm f593 imveliso yentonga enemisontoibandakanya iikhonsepthi ezimbini: ubude obupheleleyo kunye nobude bomsonto. Xa uyila kunye nokuzoba, ubude obupheleleyo be-screw bunokuqokelelwa ngokuthe ngqo ngokwezi pharamitha zilandelayo: ubude obupheleleyo be-screw = i-stroke esebenzayo + ubude be-nut + umda woyilo + ubude benkxaso kuzo zombini iziphelo (ukuthwala ububanzi + ukutshixa ububanzi be-nut + umda ) + Ubude bomdibaniso wegalelo lamandla (ukuba udibaniso lusetyenzisiwe, lumalunga nesiqingatha sobude bokudityaniswa + komda). Kubaluleke ngakumbi ukuba uqaphele ukuba ubude be-screw bude kakhulu (ubukhulu kuneemitha ezi-3) okanye umyinge we-aspect ratio mkhulu kakhulu (ungaphezulu kwama-70), uyilo kunye nokusetyenziswa kwayo kunokufuna ukuqwalaselwa ngokukodwa.
