Kushivirira uye kuonekwa kwekubatanidzwa kwe thread
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.
5. Kuyera kweshinda
1. Kuyera kwakazara
Kutarisa shinda ine shinda yegeji kuyerwa kwakadzama.Mukugadzira batch, shinda yakajairika inoshandiswa yakazara kuyerwa nzira.Kuyerwa kwakadzama kunoitwa pachishandiswa shinda yegeji (yakazara muganhu geji) zvichienderana nemaitiro ekukwana kwedhayamita yeshinda yakaunzwa kare (iyo Taylor musimboti). thread geuge yakakamurwa kuita "pass gauge" uye "stop gauge".Paunenge uchiyedza, iyo "pass gauge" inogona kubudirira kupeta neworkpiece, uye "stop gauge" haigone kukora kana screw isina kukwana, ipapo shinda inokodzera.Pane zvinopesana, "pass gauge" haigoni kutenderera, zvichiratidza kuti nut idiki, bhoti yakakura kwazvo, uye thread inofanira kugadziriswa.Apo "stop gauge" inogona kupfuura nepakati pebasa rekushanda, zvinoreva kuti nut yakakura kwazvo, bhoti idiki, uye tambo inorasa.
2. Kuonekwa kumwe chete
(1) Kuyera dhayamita yeshinda nenzira yemapini matatuNzira yepini-nhatu inonyanya kushandiswa kuyera dhayamita imwe yepakati yeshinda dzekunze chaidzo (senge shinda dzeplug geji, shinda dzelead screw, nezvimwewo).Pakuyera, isai tsono nhatu dzehupamhi hwedhayamita imwe chete mumikoto yeshinda yakayerwa zvakatevedzana, uye shandisa chinoyera kana chemuchina chekuyeresa chinhambwe chetsono M, sezvakaratidzwa mumufananidzo 9-9 (a).Maererano nenzwi rinozivikanwa P reshinda yakapimwa nehafu yeAngle a/2 yerudzi rwezino, imwe yepakati dhayamita d2s yeshinda yakapimwa inoverengwa nekutsikirira fomula.
2. Chiyero chimwe 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 dhayamita
Kukura kweiyo inoshanda yepakati dhayamita inokanganisa spinability, uye ukuru hweiyo chaiyo yepakati 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) Kureba uye giredhi chaiyo
Iyo screw screw urefu yakakamurwa kuita mhando nhatu: ipfupi, yepakati uye yakareba, inoratidzwa nekodhi S, N uye L, zvichiteerana.Izvo zvakakosha zvinoratidzwa muTable 9-5
Kana mwero wekushivirira weshinda ukagadziriswa, kureba kwesiruu, ndipo pakakwirira kuwedzera kwepitch kutsauka uye zino hafu yeAngle kutsauka kunogona kuve.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.
