Iyo yekuwedzera bhaudhi ndeye yakakosha shinda yekubatanidza inoshandiswa kugadzirisa pombi rutsigiro / kusimudza / bracket kana midziyo pamadziro, pasi kana mbiru.Magiredhi ecarbon steel bolts akakamurwa kuita 3.6,4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9, 12.9 nemamwe magiredhi anopfuura 10. Nhamba dzisati dzapfuura uye mushure meiyo decimal inoteedzana inoratidza iyo yezita rekusimba simba uye goho reshiyo. yezvinyorwa zvebhaudhi, semuenzaniso: kumaka 8.8 mabhaudhi kunoratidza kuti kusimba kwesimba rezvinhu kunosvika 800MPa, uye goho simba 0.8, ndiko kuti, goho rayo rinosvika 800 × 0.8 = 640MPa.
Zvishandiso:
Magiredhi emabhaudhi ekuwedzera akakamurwa kuita 45, 50, 60, 70 uye 80. Zvinyorwa zvakakamurwa zvakanyanya kuita austenite A1, A2, A4;Martensite uye ferrite C1, C2, C4;Kumiririra kwayo, semuenzaniso A2-70;”- ” pamberi uye shure inoratidza bhaudhi zvinhu uye giredhi resimba zvichiteerana.(1) Bolt zvinhu zvinowanzoshandiswa: Q215, Q235, 25 uye 45 simbi, yakakosha kana yakakosha chinangwa chekubatanidza zvikamu, inogona kusarudza 15Cr, 20Cr, 40Cr, 15MnVB, 30CrMrSi uye mamwe maitiro akakwirira emagetsi esimbi yealloy.(2) Kushungurudzika kunobvumirwa Kushungurudzika kunobvumirwa kwekubatanidzwa kwe threaded kune chokuita nemutoro wekutakura (static, variable load), kana kubatanidzwa kwakasimbiswa, kana preload inoda kudzorwa, uye zvinhu uye saizi yemaitiro eiyo threaded yekubatanidza.
rudzi:
Iyo giredhi yemabhaudhi esimbi isina tsvina yakakamurwa kuita 45, 50, 60, 70, 80, zvinhu zvacho zvakakamurwa zvakanyanya kuita austenite A1, A2, A4, martensite uye ferrite C1, C2, C4, nzira yayo yekutaura senge A2-70, "imwe" pamberi uye mushure zvakateerana ratidza bhaudhi zvinhu uye giredhi resimba.
inoumba: Iyo yekuwedzera bhaudhi ine countersunk bhaudhi, yekuwedzera chubhu, flat washer, chitubu washer, uye hex nati.
Paunenge uchishandiswa, zvinodikanwa kuchera gomba rehukuru hunoenderana pamutumbi wakamisikidzwa uine chibooreso (sando), wozoisa bhaudhi uye chubhu yekuwedzera mugomba, uye simbisa nati kugadzira bhaudhi, yekuwedzera chubhu. , chikamu chekuisa uye muviri wakagadziriswa unowedzera zvakasimba mune imwe.Mushure mekusimbisa kuchawedzera, muswe webhaudhi une musoro mukuru, bhaudhi kunze rakaisa yakakura zvishoma kudarika dhayamita yebhoti yakatenderedza pombi, chikamu chemuswe chine mazaru akawanda, apo bhaudhi yakasimbiswa, muswe wemusoro mukuru uchaendeswa kune kuvhurwa kwepombi mukati, pombi yakakura, kuzadzisa chinangwa chekuwedzera, uye ipapo bhaudhi rakagadzikwa pasi kana kumadziro, kuzadzisa chinangwa chemidzi. .
Performance kirasi 4.6 mabhaudhi ekuwedzera, zvichireva kuti: 1, iyo yezita rekusimba simba rekuwedzera bhoti zvinhu zvinosvika 400MPa level;2.The flexion reshiyo yekuwedzera bhoti zvinhu ndeye 0.6; 3, iyo zita regoho simba rekuwedzera bhoti zvinhu ndeye 400 × 0.6 = 240MPaChirevo chedanho rekuita kwebhaudhi yekuwedzera chiyero chepasirese, chiyero chekuita chakafanana chebhaudhi yekuwedzera. , pasinei nekusiyana kwezvinhu uye kwakabva, kushanda kwayo kwakafanana, dhizaini inogona kungosarudza danho rekuita.
Nyaya dzinoda kutariswa:
1, kudzika kudzika: kudzika kweiyo chaiyo kuvakwa kwakanakisa kupfuura kureba kwechubhu yekuwedzera inenge 5 mm.Chero bedzi yakakura kudarika kana yakaenzana nehurefu hwechubhu yekuwedzera, kureba kwebhoti yemukati yekuwedzera yakasara muvhu yakaenzana kana kuti pasi pehurefu hwechubhu yekuwedzera.2, zvinodiwa zvemukati wekuwedzera bhoti. pasi, chokwadi, zvakanyanya kuoma zviri nani, zvinoenderanawo nesimba rechinhu chaunoda kugadzirisa.Simba resimba rakaiswa mukrete (C13-15) rakapetwa kashanu kuti mumuviri wezvidhinha.3.Mushure mekuisa nemazvo iyo M6/8/10/12 yemukati yekuwedzera bhaudhi mukongiri, iyo yakakwana yakanyanya static simba ndeye 120/170/320/510 kg zvichiteerana.Iyo yekuisa nzira yemukati yekuwedzera bolt haina kuoma zvakanyanya, iyo chaiyo yekushanda ndeyotevera;Kutanga sarudza chibooreso che alloy chine dhayamita yakafanana nemhete yekuwedzera (chubhu) ye screw yekuwedzera, isa pachibooreso chemagetsi uye wozodhirowa pamadziro, kudzika kwegomba kwakafanana nekureba kwebhaudhi. , wobva waisa screw kit yekuwedzera pasi kune gomba, rangarira;Usaita screw kure sikuruu, kudzivirira gomba kuchera iri yakadzika apo bhaudhi akawira mugomba uye hazvina kunaka kutora kunze.Wozopeta sikururu 2-3 bhaudhi mushure mekunzwa kuti bhaudhi yekuwedzera yakasimba asi haina kusimuka wobva wapukuta sikururu.
