Uchungechunge olujwayelekile

Uchungechunge olujwayelekile lobubanzi nephimbo (GB/T193-2003)

Uchungechunge olujwayelekile lwe-diameter ne-pitch oluhlanganisiwe luzohambisana nemibandela yeThebula 1. Kuthebula, ukuphakama kufanele kukhethwe kumugqa ofanayo ne-diamete.

Ububanzi bekholomu.Khetha uchungechunge lokuqala lwamadayamitha kuqala, uchungechunge lwesibili lwamadayamitha okwesibili, bese uhlelo lweMfundo Ephakeme lugcine

Gwema ukukhetha ukuphakama kubakaki ngangokunokwenzeka.

Imicu emibili ebekiwe enamanothi (a, b) etafuleni kufanele isetshenziselwe ukusetshenziswa okuqondile okuchazwe ngakho.

Uchungechunge olukhethekile lwamadayamitha nephimbo:

Ngobubanzi obujwayelekile bochungechunge, uma iphimbo elikhethekile elincanyana kunalelo elishiwo kuThebula 1 lidingeka, kufanele likhethwe kulokhu okulandelayo:

3mm, 2mm, 1.5mm, 1mm, 0. 75mm, 0. 5mm, 0. 35mm, 0. 25mm, 0. 2mm

Ukukhetha iphimbo elincane kunaleso elishiwo kuThebula 1 kuzokwandisa ubunzima bokukhiqiza intambo

Ngokuhambisana nephimbo kuThebula 2, ubukhulu bobubanzi obukhethekile obukhethiwe akufanele bube ngaphandle kwebanga lobubanzi obuchazwe kuThebula 2.

7.3 Ukubekezelelana kwe-diameter ephezulu

a) Ukubekezelelwa kwedayamitha enkulu yochungechunge lwangaphandle:

Ukubekezelelana kweBanga lesi-6: Ta (6)-180P3-3.15

Ukubekezelelwa kwezinga lesi-4: Ta (4) =0.63Ta (6)

Ukubekezelelana kweBanga lesi-8: Ta (8) =1.6Ta (6)

I-Ta ikalwa ngama-microns bese u-P ulinganiswa ngamamilimitha.

b) Ukubekezelela okuncane kochungechunge lwangaphakathi:

Ukubekezelelana kweBanga lesi-6:1) Lapho 0.2mm1mm:1 (6) =230P0.7

Ukubekezelelwa kwezinga lesi-4: Tpi (4)=0.63 Tp (6)

:Ukubekezelelana kweBanga lesi-5: I-Toi (5) =0.8 Tbi (6); ukubekezelelana kweBanga lesi-7: Tpi (7) =1.25 Tbi (6); Ukubekezelelana kweBanga lesi-8: Ku-(8) = 1.6Tp1 (6To kukalwa ngama-microns kanye no-P ngamamilimitha.

Umkhawulo wokuchezuka (GB/T2516-2003)

Amanani okuchezuka omkhawulo wedayamitha emaphakathi nentambo engaphezulu aboniswa kuThebula 1 (kususiwe).

Noma yiliphi iphuzu kuphrofayela engezansi yezintambo zangaphakathi nezangaphandle akufanele zeqe iphrofayili eqinile ephezulu enqunywa iphrofayili eyisisekelo kanye nendawo yokubekezelela indawo.Inani lokuchezuka lobubanzi betafula linikezwa ngokuhambisana nobude bokusika be-H/6, okuyinto ingasetshenziswa ukubala ukucindezeleka kwentambo yangaphandle.

Qaphela: Ukuchezuka kobubanzi obuncane bomucu wangaphandle kubalwa ngokuthi -(les + H/6).Ngaphandle kwalapho kucaciswe ngenye indlela, indawo yokubekezelela isebenza kuchungechunge ngaphambi kokucwenga.Ngemva kokucwenga, alikho iphuzu kuphrofayela yochungechunge okufanele lidlule iphrofayili yezinyo eliqinile eliphezulu elinqunywa indawo yokubekezelela indawo H noma h. Qaphela: Amabhande okubekezelela asebenza kuphela emiculweni eboshwe kancane.Isibonelo, intambo ye-electroplating.
