Yakatwasuka tambo yekubatanidza simba senge majoini anosimbisa kubatana mu90s yezana ramakore rechi 20 ndiyo yazvino mafambiro epasirese, yemhando yekubatana yakagadzikana yakavimbika, yakakwirira yakabatana simba, yakaenzana neiyo yemaoko ekukanya bhiridha majoini, uye zvakare ine taper shinda yekubatanidza kuvaka nyore. , kukurumidza hunhu, nokudaro kuratidzwa kune simbi yakatwasuka shinda yekubatanidza hunyanzvi hwekubatanidza hunyanzvi hwakaunza qualitative prance.Parizvino, kune akawanda marudzi enzira dzakatwasuka dzekubatanidza tambo munyika yedu.
Yakatwasuka shinda yekubatanidza inonyanyo sanganisira kushungurudza yakatwasuka shinda yekubatanidza uye kukunguruka yakatwasuka shinda yekubatanidza.Aya maitiro maviri anosarudza nzira dzakasiyana dzekugadzirisa, kusimudzira kugona kwesimbi yekupedzisira shinda, kusvika pajoinhi uye yekusimbisa base zvinhu uye imwe yakasimba vavariro.
Upsetting straight thread joint: mubatanidzwa wakaumbwa nekuvharika kweshinda yakatwasuka uye shinda dzekubatanidza dzakaitwa nekuvhiringa magumo esimbi.Nzira yacho ndeiyi:
Kutanga, iyo simbi yesimbi inopera inogumburwa nekugumburisa midziyo, uye ipapo shinda inogadziriswa.Iyo dhayamita yeshinda haisi pasi peiyo dhayamita yesimbi bar base zvinhu, kuitira kuti majoini nehwaro zvinhu zvisvike simba rakaenzana.Kune dzimwe nyika shinda yakatwasuka inogumbura majoini, simbi yayo inopera inopisa inogumbura uye inotonhora inogumbura.Chinangwa chikuru chekupisa chinopisa ndechekubvisa kushushikana kwemukati panguva yekugumburwa, asi mari yemidziyo yekupisa yakakwirira.Munyika yedu, iyo simbi yesimbi inopera yetambo yakatwasuka inomutsa yakabatana inonyanya kutonhora inogumbura, iyo ine kudiwa kwakanyanya kweductility yesimbi bar.Kune simbi simbi ine yakaderera ductility, inogumbura kunaka kwakaoma kudzora, uye zviri nyore kuratidzika se brittle fracture chitarisiko.
Zvakanakira kushatisa tambo yakatwasuka isimba rakakura, kukurumidza kuvaka saiti kumhanya, kuderera kwekushanda kwevashandi, simbi yakatwasuka shinda musoro zvese zvakafanogadzirwa kare, saiti yekubatanidza yekuisa.Kushaikwa kuri mukugumburisa muitiro zviri nyore kuoneka anogumbura chitarisiko, kamwe kugumbuka zvinotofanira kugura re-kugumburisa;Munguva yekugumburwa, kushushikana kwemukati kunoitika, kumwe ductility yesimbi inogumbura inodzikira, uye zviri nyore kuita brittle yakatyoka chitarisiko.Iyo screw thread processing inoda maitiro maviri uye maviri seti emidziyo kuti apedze.
Kukungurutsa shinda yakatwasuka: chibatanidza chinoumbwa nekurumwa kweshinda yakatwasuka uye shinda dzekubatanidza dzakagadzirwa nekumonera kana kudzvinya (kumoneredza) mbabvu kumucheto kwesimbi kana mushure mekubvisa mbabvu.
Yetatu, sleeve yekukanya yakabatana: mushure mekukanya simba kugadzira iyo yakabatana yepurasitiki deformation yesimbi sleeve uye ribbed simbi yakavharika zvakavharika pajoini.Pane nzira mbiri, radial kneading yekubatanidza uye axial kneading yekubatanidza.Nekuti iyo axial kneading yejoint site yekuvaka haina kunaka uye iyo yekubatana mhando haina kugadzikana, haisati yaitwa;Unyanzvi hwekukanya radial uye majoini zvakashandiswa zvakanyanya.Ikozvino sleeve yekukanya majoini anoshandiswa mupurojekiti majoini ekukanya radial.Nekuda kwehunhu hwayo hwakanakisa, zvibatanidza zvekukanya maoko zvakashandiswa zvakanyanya muinjiniya yekuvaka muChina kubva kutanga kwema1990 kusvika zvino.
