High-simba bhaudhi yekubatanidza iri kuburikidza nehukuru simbisa pretension bhoti tsvimbo mukati mekubatanidza ndiro plate clamping chidimbu, inokwana kuburitsa yakawanda friction, kuitira kuvandudza kutendeseka uye kuoma kwekubatana, kana shear, zvinoenderana nezvinodiwa dhizaini uye kushushikana kwakasiyana, kunogona kukamurwa kuita friction type yakakura simba bhoti yekubatanidza uye yakakwirira simba bhoti inobatanidza mbiri yekumanikidza mhando, ndiyo yakakosha mutsauko pakati peiyo miganhu yenyika yakasiyana, kunyangwe iri mhando yebhaudhi, asi kuverenga. nzira, zvinodiwa, kuwanda kwekushandisa kwakasiyana kwazvo.Mukuveura dhizaini, yakakwirira-simba bhoti friction yekubatanidza inoreva iyo yakanyanya kukwesha simba inogona kupihwa nebhaudhi yekusimbisa simba pakati pekunze kweshear force uye yekusangana pamusoro pendiro semuganhu. state, kureva, kuve nechokwadi chekuti mukati nekunze shear simba rekubatanidza haripfuure iyo yakanyanya friction force panguva yese sevhisi.nguva.Hakuzovi nehukama hunotsvedza deformation yeplate (iyo yepakutanga void pakati pe screw uye gomba remadziro rinogara rakachengetedzwa) .Mukugadzira shear, pressure type high simba bolt connection inobvumirwa mushear force yekunze inodarika iyo yakanyanya friction force. , iyo hama inotsvedza pakati peyakabatana plate deformation, kusvika bhaudhi rasangana nemadziro egomba, wozobatana pabhaudhi shaft shear uye kudzvanywa pamadziro egomba uye kukweshana pakati peiyo yekubatanidza pamusoro penzvimbo yekubatanidza simba, pakupedzisira kusvika shaft shear kana kumanikidza gomba kukuvadzwa kwemadziro sekutobvuma shear limit state.Muchidimbu, friction type mabhaudhi akasimba-akasimba uye mabhaudhi anodzvanyirira emhando yepamusoro-simba mabhaudhi ndiwo chaiwo mabhaudhi emhando, asi dhizaini.
Slippage haina kutariswa.Friction type yakakwirira-simba bhaudhi haigone kutsvedza, bhaudhi haitore simba rekugera, kana ikangotsvedza, dhizaini inoonekwa seyasvika kune yekutadza nyika, yakakura muhunyanzvi tekinoroji. uye zviumbu zvine simba.Kukuvadzwa kwekupedzisira kwakafanana neyemabhaudhi akajairwa (bolt shear kana simbi yekupwanya ndiro). Kubva pamaonero ekushandiswa:
Kubatana kwebhoti yenhengo huru yechivako chekuvaka inowanzogadzirwa nepamusoro-simba bhoti.Mabhoti akajairika anogona kushandiswa zvakare, mabhoti ane simba haagone kushandiswa zvakare.Mabhoti ane simba guru anowanzoshandiswa pakubatanidza kusingaperi.
High-simba mabhaudhi ari prestressed mabhaudhi, friction type ine torque wrench kuti ishandise iyo yakatemwa prestress, pressure type screw off the plum head.Ordinary bolts have poor shear performance uye inogona kushandiswa musecondary structural parts.Ordinary bolts inoda kuomeswa chete.
Mabhaudhi akajairika anowanzo kirasi 4.4, kirasi 4.8, kirasi 5.6 uye kirasi 8.8.High simba mabhaudhi kazhinji 8.8 uye 10.9, iyo 10.9 ndiyo yakawanda.
8.8 ndiyo giredhi rakafanana ne8.8S. Mamichina maitiro uye nzira dzekuverenga dzemabhoti akajairwa uye epamusoro-simba bhoti zvakasiyana.Kushungurudzika kwepamusoro-simba bhoti kunotanga kuburikidza nekushandiswa kwe pretension P mukati maro, uye ipapo friction resistance pakati pekubatana kwepamusoro pechimedu chekubatanidza kutakura mutoro wekunze, uye bhaudhi rakajairwa rinotakura zvakananga mutoro wekunze.
Yakakwirira simba bhaudhi yekubatanidza ine zvakanakira zvekuvaka nyore, kuita kwakanaka kwemakanika, dismountable, kuneta kuramba, uye pasi pechiito chesimba remutoro, inova nzira inovimbisa yekubatanidza.
High simba bhaudhi ndeye kushandisa yakakosha chipanera kuomesa nati, kuitira kuti bhaudhi ribudise huru uye inodzorwa pretension, kuburikidza nenati nendiro, kuti ibatanidzwe nehuwandu hwakafanana hweprepressure.Pasi pechiito che pre-pressure. , simba guru rekukwenya richagadzirwa pamwe nepamusoro pechidimbu chakabatanidzwa.Zviripachena, chero bedzi iyo axial simba iri shoma pane iyi friction force, nhengo haizotsvedza uye kubatana hakuzokuvadzwa.Iyi ndiyo nheyo yepamusoro-simba rekubatanidza bhaudhi.
Yakakwirira simba rekubatanidza bhaudhi rinoenderana nekukwesha kwesimba pakati penzvimbo dzekubatanidza dzezvikamu zvinobatanidza kudzivirira kutsvedza.Kuti tive nefosi yekukwesha yakakwana panzvimbo yekubatana, zvinodikanwa kuwedzera simba rekurovedzera uye friction coefficient yenzvimbo dzekusangana dzenhengo. Simba rekubatanidza pakati penhengo rinowanikwa nekushandisa pretension kune mabhaudhi, saka mabhaudhi anofanira. kuve yakagadzirwa nesimbi yakakwirira-yakasimba, ndicho chikonzero ivo vanonzi ma-high-strength bolt connections.
Musimba rakasimba rekubatanidza bhoti, friction coefficient ine simba guru pakutakura simba.Muedzo unoratidza kuti friction coefficient inonyanya kukanganiswa nemhando yekubatana kwepamusoro uye zvinhu zvechikamu.Kuitira kuwedzera friction coefficient of contact surface. , nzira dzakadai sekuputika kwejecha uye wire brush yekuchenesa inowanzoshandiswa pakuvaka kubata nzvimbo yekubatana yezvikamu mukati mehutano hwekubatanidza.
