6,threadkuyerwa

Kana iri shinda yakajairika, thread ring gauge kana plug geji inoshandiswa kuyera.

Nekuda kwekuti shinda yeparameter yakawanda, hazvibviri kuyera imwe neimwe parameter yeshinda imwe neimwe, kazhinji isu tinoshandisa shinda yegeji ( thread ring gauge, thread plug geji) kutonga shinda zvizere.Iyi nzira yekuongorora ndeye nzira yekugamuchirwa yekuongorora yemhando yegungano reanalogi, kwete chete iri nyore, inovimbika, uye chaiyo inodiwa ine shinda yakajairwa ndeyechokwadi, nekuti iyi ndiyo yave nzira yekuongorora yekugamuchirwa yakawanda inoshandiswa mukugadzirwa chaiko parizvino.

7, kuyerwa kweshinda (yepakati dhayamita)

Mukubatanidza shinda, saizi yepakati chete dhayamita ndiyo inosarudza chimiro cheshinda, saka nzira yekutonga nemazvo kana dhayamita yepakati inokodzera ndiyo yakakosha.Zvichienderana nenyaya yekuti saizi yepakati yedhayamita inofanirwa kuve nechokwadi chekuti basa rekutanga rebasa reshinda rinowanikwa, mucherechedzo wekukodzera kwedhayamita yepakati unotsanangurwa muchiyero: "Ipakati dhayamita yeshinda chaiyo haifanirwe kudarika iyo dhayamita yepakati. dhayamita yepakati peiyo huru yakasimba mazino profile.Dhiyamita imwe yepakati yechikamu chipi nechipi cheshinda chaiyo haifaniri kudarika dhayamita yepakati pechimiro chiduku zvikuru chezino rakasimba.”

Single dhayamita kuyerwa zvakanyanya nyore nzira ine marudzi maviri panguva ino, imwe ndeye kushandisa shinda dhayamita micrometer kuyera dhayamita, imwe ndeye kushandisa matatu tsono nzira kuyerwa (Ndakashandisa matatu tsono nzira kuyerwa).

8. Thread inoenderana giredhi:

Thread fit ndiyo saizi yakasununguka kana yakamanikana pakati peshinda dzekupura, uye giredhi refit isanganiswa yakatsanangurwa yekutsauka uye kushivirira kunoshandiswa kune mukati nekunze shinda.

(1) Pashinda inchi imwe chete, pane shinda nhatu dzeshinda: 1A, 2A uye 3A yeshinda yekunze, uye magiredhi matatu: 1B, 2B uye 3B yeshinda yemukati, ese ari gap fit.Iyo yakakwira nhamba yegiredhi, iyo inotowedzera kukwana.Mutambo yeinch, kutsauka kunotsanangurwa kugiredhi 1A ne2A chete, giredhi 3A i zero, uye giredhi 1A ne2A zvakaenzana.

Iyo yakakura nhamba yemagiredhi, idiki iyo kushivirira, sezvakaratidzwa mumufananidzo:

1) Kirasi 1A uye 1B, yakasununguka kwazvo kirasi yekushivirira, yakakodzera kushivirira kwakakodzera kwemukati nekunze tambo.
2) Kirasi 2A uye 2B ndiwo makirasi akajairika ekushivirira makirasi anotsanangurwa muBritish akatevedzana emakanika fasteners.
3) Kirasi 3A uye 3B, sikuruu kuti iite yakanyatsokodzera, yakakodzera zvisungo zvine kushivirira kwakasimba, kune kiyi dhizaini yekuchengetedza.
4) Kune shinda dzekunze, pane kutsauka kwakakodzera kwekirasi 1A uye 2A, asi kwete yekirasi 3A.Kirasi 1A kushivirira i50% yakakura kupfuura kirasi 2A kushivirira, 75% yakakura kupfuura iyo kirasi 3A kushivirira uye 30% yakakura kupfuura iyo kirasi 2B kushivirira kune yemukati tambo.1B i50 muzana yakakura kupfuura 2B uye 75 muzana yakakura kupfuura 3B.

(2)metric thread, shinda yekunze ine common thread giredhi: 4H, 6E, 6g uye 6H, shinda yemukati ine common thread giredhi: 6g, 6H, 7H.(Yemazuva ese screw thread accuracy giredhi yakakamurwa kuita I, II, III, kazhinji II) mushinda yemetric, kutsauka kwekutanga kweH uye H i zero.Iko kutsauka kwakakosha kweG kwakanaka, uye iyo yeE, F, uye G haina kunaka.Sezvinoratidzwa mumufananidzo:

1) H ndiyo yakajairwa kushivirira nzvimbo chinzvimbo chetambo dzemukati, uye haiwanzo shandiswa seyepamusoro pekuvhara, kana ine yakatetepa phosphating layer.Iko kutsauka kweiyo G chinzvimbo kunoshandiswa kune akakosha zviitiko, senge gobvu plating, uye haiwanzo kushandiswa.

2) G inowanzoshandiswa kuputira 6-9um yakaonda, senge 6h mabhaudhi anodiwa neadhirowa yechigadzirwa, shinda isati yaiswa ichatora 6g yekushivirira bhendi.

3) Iyo tambo inokwana yakanyatso kusanganiswa kuita H/ G, H/ H kana G/ H, yemabhaudhi, nzungu uye dzimwe dzakanatswa fastener shinda, chiyero chinokurudzirwa 6H/6g kukwana.

Yepakati giredhi yekururama kune akajairwa threads
Nut: 6H bhaudhi: 6g
Yepakati giredhi yekururama kweshinda dzine kuremerwa kwakakora
Nut: 6G Bolt: 6E
High precision giredhi
Nut: 4H Bolt: 4H, 6h
