Thread kushivirira uye kuongorora

Kushivirira uye kuonekwa kwe threadbonding

Chinangwa chechitsauko chino ndechekunzwisisa hunhu hweyakajairwa tambo yekuchinjika uye kushandiswa kwekushivirira zviyero.Chinodiwa chekudzidza ndechekunzwisisa kupesvedzera kwemhosho huru dzejometri yeshinda yakajairika pane kuchinjana;Gadzira pfungwa yedhayamita yekuita shinda;Nekuongorora kugoverwa kwetambo yekushivirira zone, tenzi hunhu hweakajairwa shinda kushivirira uye kukwana uye kusarudzwa kweshinda chaiyo;Nzwisisa zvinhu zvinokanganisa kufambiswa kwechokwadi kwemushini screw.

Rudzi rweshinda uye zvinodiwa zvekushandisa

1, shinda yakajairika

Kazhinji inonzi fastening thread, inonyanya kushandiswa kubatanidza uye kusungirira zvikamu zvakasiyana-siyana zvemagetsi.Zvinodiwa zvekushandiswa kwerudzi urwu rwekubatanidzwa kwe threaded screwability (nyore kuungana uye disassembly) uye kuvimbika kwekubatanidza.

2. Dhiraivha thread

Rudzi urwu rweshinda runowanzo shandiswa kutumira mafambiro kana simba.Iko kushandiswa kwekubatanidzwa kwe threaded kunoda kuvimbika kwesimba rinopfuudzwa kana kurongeka kwekufambiswa kwekutamisa.

3. Tight thread

Mhando iyi yeshinda inoshandiswa kuvhara majoini.Iko kushandiswa kweshinda zvinodiwa kwakaomarara, hapana kudonha kwemvura, hakuna kubuda kwemhepo uye hakuna kubuda kwemafuta.

Kugadzirisa nharo

Tambo yekunze inosangana nemitemo inoenderana yekushandiswa muTable 1 kana ichiedzwa ne-end-end thread ring gauge uye ne-end-end thread ring geji yechiyero ichi, uye inosangana nemitemo inoenderana nekushandiswa muTable Al painoedzwa ne -end smooth ring gauge (kana snap gauge) uye through-end smooth snap gauge (kana ring gauge) yechiyero ichi, inotongwa kuti inokwanisa.Tvudzi yemukati inopindirana nemitemo yekushandiswa muTable 1 painoedzwa nayo. iyo yekupfuura-yekupedzisira plug geji uye yekumira-yekupedzisira plug geji yeiyi mwero uye inoenderana mitemo yekushandiswa muTable Al kana yakaedzwa ne-ekupedzisira-inotsvedzerera plug geji uye kuburikidza-yekupedzisira yakatsetseka plug geji yeAppendix A yechiyero ichi T.5 Kuti uderedze kusawirirana panguva yekuongorora, mushandisi achashandisa shinda itsva kana shoma shoma yakapfekwa uye inopfekwa kana kuswedera painogumira pakugadzira shinda.Dhipatimendi rekuongorora kana mumiriri wemushandisi achashandisa iyo yekupedzisira-tambo geji ine yakawanda kupfeka kana kuswedera pedyo neinogumira kupfeka uye itsva kana kushoma kupfeka inomira-yekupedzisira shinda yegeji pakugamuchira T shinda.1.6 Pakaitika kukakavara panguva yekuongorora. , kana iyo geji yeshinda inosarudza iyo workpiece shinda kuti ikwanise zvinoenderana nezvinodiwa zvechiyero ichi, iyo workpiece shinda ichabatwa seyakakodzera.

Kuyera kumwe chete

Kune hukuru hukuru tambo dzakajairwa, tambo dzakakwana uye tambo dzekutyaira, mukuwedzera kune kutenderera uye kuvimbika kwekubatanidza, kune humwe huchokwadi uye hunoshanda zvinodiwa, uye chiyero chimwe chinowanzo shandiswa mukugadzira.

Kune nzira dzakawanda dzekuyera shinda imwe chete, iyo inonyanya kujaira ndeye kushandisa iyo universal tool maikorosikopu kuyera dhayamita, gomo nehafu Engle yeshinda.Chishandiso chemicroscope chinoshandiswa kukudza chimiro cheshinda yakayerwa uye kuyera kukwirira kwayo, hafu yeAngle uye yepakati dhayamita zvichienderana nemufananidzo weshinda yakapimwa, saka nzira yacho inonzi zvakare mufananidzo nzira.

Mukugadzirwa chaiko, nzira yekuyera mapini matatu inoshandiswa kuyera dhayamita yepakati yeshinda yekunze.Iyi nzira iri nyore, yakakwirira yekuyera kurongeka uye inoshandiswa zvakanyanya

Pfupiso pfupi

1. Common thread

(1) Matemu makuru uye geometric parameter yeshinda dzakajairwa ndeiyi: mazino emhando, dhayamita hombe (D, d), dhayamita diki (D1, d1), dhayamita yepakati (D2, d2), dhayamita yepakati inoshanda, dhayamita imwe yepakati ( D2a, d2a) chaiyo yepakati dhayamita, pitch (P), zino mhando Engiro (a) uye zino mhando hafu Engle (a/2), uye sikuruu kureba.

(2) Pfungwa yepakati dhayamita yechiito uye mamiriro akakodzera epakati dhayamitaUkuru hweiyo inoshanda yepakati dhayamita inokanganisa spinability, uye saizi yepakati chaiyo dhayamita inokanganisa kuvimbika kwekubatana.Kunyangwe iyo dhayamita yepakati inokodzera kana kwete inofanirwa kutevedzera iyo Taylor musimboti, uye ese ari maviri chaiwo epakati dhayamita uye anoshanda epakati dhayamita anodzorwa mukati mekushivirira zone yepakati dhayamita.

(3) Common thread tolerance level Muchidimbu chekushivirira kweshinda, kushivirira kwe d, d2 uye D1, D2 kunotsanangurwa.Matanho avo ekushivirira anoratidzwa muTafura 9-1.Hapana kushivirira kunotsanangurwa nenamo uye mazino mhando (inodzorwa nepakati dhayamita kushivirira zone), uye hapana kushivirira kunotsanangurwa dhayamita diki d yeshinda yekunze uye dhayamita hombe D yeshinda yemukati.

(4) Kutsauka kwekutanga Kune shinda dzekunze, kutsauka kwekutanga ndiko kutsauka kwepamusoro (es), pane e, f, g, h marudzi mana;Kune shinda dzemukati, kutsauka kwekutanga ndiko kutsauka kwepasi (El), kune marudzi maviri eG uye H. The tolerance giredhi uye yakakosha kutsauka inoumba shinda kushivirira zone.Chiyero chenyika chinotsanangura nzvimbo yekushivirira, sezvakaratidzwa muTebhura 9-4.Kazhinji, iyo yakasarudzika nzvimbo yekushivirira inotsanangurwa mutafura inofanirwa kusarudzwa kusvika pazvinobvira.Kusarudzwa kwenzvimbo dzekushivirira kunotsanangurwa muchitsauko chino.

(5) Screw kureba uye giredhi chaiyoIkureba sikururu yakakamurwa kuita marudzi matatu: mapfupi, epakati uye akareba, anoratidzwa nekodhi S, N uye L, zvichiteerana.Hukoshi hunoratidzwa muTable 9-5Kana mwero wekushivirira weshinda ukagadziriswa, kureba kwescuruu, kunobva kwawedzera kutsauka kwepitch uye zino hafu yeAngle deviation inogona kuva.Naizvozvo, shinda zvinoenderana nezera rekushivirira uye kureba kwescrew ine matatu echokwadi mazinga: kurongeka, yepakati uye yakaoma.Kushandiswa kwenhanho yega yega inotsanangurwa muchitsauko chino.Nechiyero chakafanana chechokwadi, chiyero chekushivirira chetambo chinofanira kuderedzwa nekuwedzera kwekutenderera kureba (ona Tafura 9-4).

(6) Kumakwa kweshinda pamufananidzo kunoratidzwa mune zvinoenderana nechitsauko chino.

(7) Kuonekwa kwetambo kwakakamurwa kuita kuwonekwa kwakazara uye kuona kamwe chete.
