Uluhlu olusemgangathweni lwedayamitha kunye nepitch (GB/T193-2003)
I-diameter kunye ne-pitch standard yokudibanisa uchungechunge luya kuhambelana ne-provisio yeThebhile 1. Kwitheyibhile, i-pitch kufuneka ikhethwe kumqolo ofanayo kunye ne-diamete.
Idayamitha yeKholamu. Khetha uthotho lokuqala lweedayamitha kuqala, uthotho lwesibini lwedayamitha okwesibini, kwaye emva koko inkqubo yeMfundo ePhakamileyo ekugqibeleni
Kuphephe ukukhetha inowuthi kwizibiyeli kangangoko.
Imisonto yobalulo emibini enamanqaku (a, b) kwitheyibhile kufuneka isetyenziswe kuphela kusetyenziso oluthile oluchazwe ngayo.
Uluhlu olukhethekileyo lweedayamitha kunye nepitch:
Kuluhlu lweedayamitha ezisemgangathweni, ukuba i-pitch ekhethekileyo encinci kuneyo ichazwe kwiThebhile 1 iyafuneka, kufuneka ikhethwe kokulandelayo:
3mm, 2mm, 1.5mm, 1mm, 0. 75mm, 0. 5mm, 0. 35mm, 0. 25mm, 0. 2mm
Ukukhetha i-pitch encinci kunaleyo ichazwe kwiThebhile 1 kuya kwandisa ubunzima bokwenziwa kwentambo
Ngokuhambelana ne-pitch kwiThebhile 2, ubukhulu bedayamitha ekhethekileyo ekhethiweyo akufanele ibe ngaphandle koluhlu lwedayamitha echazwe kwiThebhile 2.
7.3 Ukunyamezelana kwedayimitha ephezulu
a) Ukunyamezelana kwedayimitha enkulu kumsonto wangaphandle:
Ukunyamezela kweBakala 6: Ta (6)-180P3-3.15
Inqanaba lesi-4 lokunyamezela: Ta (4) =0.63Ta (6)
Ukunyamezela kwiBakala 8: Ta (8) =1.6Ta (6)
U-Ta ulinganiswa ngee-microns kwaye i-P ilinganiswa ngeemilimitha.
b) Ukunyamezelana okuncinci komsonto wangaphakathi:
Grade 6 unyamezelo:1) Xa 0.2mm1mm:1 (6) =230P0.7
Inqanaba lesi-4 lonyamezelo: Tpi (4)=0.63 Tp (6)
:Ukunyamezela kweBanga lesi-5: iToi (5) =0.8 Tbi (6); ukunyamezela kwiBakala 7: Tpi (7) =1.25 Tbi (6); ukunyamezela kwiBakala 8: Ukuya (8) = 1.6Tp1 (6To ilinganiswa ngeemicrons kunye neP kwiimilimitha.
Umda wokutenxa (GB/T2516-2003)
Umda wokutenxa amaxabiso omsonto wedayamitha ephakathi kunye nedayamitha ephezulu iboniswe kwiTheyibhile 1 (eshiyiweyo).
Naliphi na inqaku kwiprofayili esezantsi yeentambo zangaphakathi nangaphandle akufanele zigqithise iprofayili ephezulu eqinileyo egqitywe yiprofayili esisiseko kunye nendawo yokunyamezela indawo. ingasetyenziselwa ukubala uxinzelelo lwentambo yangaphandle.
Qaphela: Ukutenxa kwe-diameter encinci yentambo yangaphandle ibalwa njenge -(les + H / 6).Ngaphandle kokuba kuchazwe ngenye indlela, indawo yokunyamezela isebenza kwimisonto phambi kokwalekwa.Emva kokubekwa, akukho nqaku kwiprofayili yomsonto kufuneka idlule ubuninzi beprofayili yezinyo eliqinileyo eligqitywe yindawo yokunyamezela indawo H okanye h. Qaphela: Iibhanti zokunyamezela zisebenza kuphela kwimicu ebhityisiweyo.Umzekelo, intambo ye-electroplating.
