Yakatevedzana dhayamita uye gomo (GB/T193-2003)
Iyo dhayamita uye pitch yakajairwa musanganiswa yakatevedzana ichaenderana neprovisio yeTafura 1. Mutafura, gomo rinofanira kusarudzwa mumutsara wakafanana nediamete.
Column dhayamita.Sarudza yekutanga nhevedzano yemadhayamita kutanga, yechipiri nhevedzano yemadhayamita kechipiri, uye ipapo iyo Tertiary system yekupedzisira.
Dzivisa kusarudza nzwi mumabhuraketi zvakanyanya sezvinobvira.
Idzo tambo mbiri dzakatemerwa dzine manotsi (a, b) mutafura dzinofanirwa kushandiswa chete kune chaiyo kushandiswa kwadzinotsanangurwa.
Special nhevedzano yemadhayamita uye pitch:
Kune akajairwa akatevedzana madhayamita, kana yakakosha pitch idiki pane yakatsanangurwa muTable 1 ichidikanwa, inofanirwa kusarudzwa kubva pane zvinotevera:
3mm, 2mm, 1.5mm, 1mm, 0. 75mm, 0. 5mm, 0. 35mm, 0. 25mm, 0. 2mm
Kusarudza gomo diki pane rakatsanangurwa muTebhurari 1 kuchawedzera kuoma kwekugadzira shinda
Zvichienderana nenzwi riri muTebhurari 2, iyo yakakura yakakosha dhayamita yakasarudzwa haifanirwe kunge iri kunze kwedhayamita inotsanangurwa muTafura 2.
7.3 Pamusoro dhayamita kushivirira
a) Yakakura dhayamita kushivirira kwekunze shinda:
Giredhi 6 kushivirira: Ta (6)-180P3-3.15
Level 4 kushivirira: Ta (4) =0.63Ta (6)
Kushivirira kweGrade 8: Ta (8) =1.6Ta (6)
Ta inoyerwa nemamicrons uye P inoyerwa nemamilimita.
b) Kushivirira kudiki kweshinda yemukati:
Giredhi 6 kushivirira: 1) Kana 0.2mm1mm:1 (6) =230P0.7
Level 4 kushivirira: Tpi (4)=0.63 Tp (6)
:Grade 5 kushivirira: Toi (5) =0.8 Tbi (6); Grade 7 tolerance: Tpi (7) =1.25 Tbi (6);Grade 8 tolerance: Ku(8) = 1.6Tp1 (6To inoyerwa nemamicrons uye P mumamirimita.
Kutsauka kwemuganhu (GB/T2516-2003)
Muganho wekutsauswa kwetsika yedhayamita yepakati nepakati inoratidzwa muTebhurari 1 (yakasiiwa).
Chero chipi zvacho chiri pazasi chimiro chetambo dzemukati nekunze hachifanirwe kudarika yakanyanya kusimba mbiri yakatemerwa neiyo basic profile uye tolerance zone chinzvimbo.Kutsauka ukoshi hwedhayamita yetafura inopiwa zvinoenderana neH / 6 yekucheka urefu, iyo inogona kushandiswa kuverenga kushushikana kwetambo yekunze.
Cherechedza: Kutsauka kwedhayamita diki yeshinda yekunze inoverengerwa se -(les + H/6).Kunze kwekunge zvatsanangurwa neimwe nzira, iyo tolerance zone inoshanda kune shinda isati yaiswa.Mushure mekuputira, hapana poindi pane yeshinda profiles inofanirwa kudarika yakanyanya kusimba mazino profiles yakatemwa nenzvimbo yekushivirira chinzvimbo H kana h. Cherechedza: Mabhendi ekushivirira anongoshanda kune shinda dzakatetepa.Somuenzaniso, electroplating thread.
