Yepamusoro-simba bhaudhi yekubatanidza iri kuburikidza nehukuru simbisa pretension bhaudhi tsvimbo mukati mekubatanidza ndiro plate clamping chidimbu, inokwana kuburitsa yakawanda friction, kuitira kuvandudza kutendeseka uye kuoma kwekubatana, kana shear, zvinoenderana nezvinodiwa iyo dhizaini uye kushushikana kwakasiyana, inogona 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, chiyero chekushandiswa chakasiyana kwazvo.Mukuveura dhizaini, yakakwirira-simba bhoti friction yekubatanidza inoreva iyo yakanyanya friction simba inogona kupihwa nebhaudhi yekusimbisa simba pakati pekunze kweshear simba uye yekusangana pamusoro peplate semuganhu. nyika, ndiko kuti, kuve nechokwadi kuti simba remukati nekunze rekugera rekubatanidza haripfuuri simba rekukwesha rinopfuura mukati menguva yese yebasa.Hakuzovi nehukama hwekutsvedza deformation yeplate (iyo yekutanga void pakati pe screw negomba. madziro anogara akachengetwa) .Mukuveura dhizaini, kudzvanywa kwemhando yepamusoro yesimba bhaudhi yekubatanidza inobvumidzwa mune yekunze simba rekugera rinopfuura iyo yakanyanya kukwesha simba, iyo hama inotsvedza pakati peyakabatana plate deformation, kusvika bhaudhi rasangana nemadziro egomba, ipapo kubatana pa. bolt shaft shear uye kudzvanywa pamadziro egomba uye kukweshana pakati peiyo yekusangana pamusoro pepaneru yekubatanidza simba, pakupedzisira kusvika kune shaft shear kana kumanikidza pagomba kukuvara kwemadziro sekutogamuchira shear muganhu wenyika. kubereka mhando yepamusoro-simba mabhaudhi ndiwo chaiwo emhando imwechete yemabhoti, asi dhizaini iri
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 steel plate crushing). Kubva pamaonero ekushandiswa:
Kubatanidzwa kwebhoti yenhengo huru yechivako chekuvaka inowanzogadzirwa nepamusoro-simba bhoti.Mabhoti akajairika anogona kushandiswa zvakare, mabhoti ane simba haakwanisi 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 has 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 ndiko kutanga kwezvose kuburikidza nekushandiswa kwe pretension P mukati maro, uye ipapo iyo friction resistance pakati pekubatana kwepamusoro pechimedu chekubatanidza kutakura mutoro wekunze, uye bhaudhi rakajairwa rinotakura zvakananga mutoro wekunze.
Yakakwira simba bhaudhi yekubatanidza ine zvakanakira zvekuvaka zviri nyore, yakanaka mechanical kuita, 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 chete nepamusoro pechidimbu chakabatanidzwa. Zviripachena, chero bedzi iyo axial simba iri shoma pane iyi friction simba, nhengo haizotsvedza uye kubatana hakuzokuvadzwa. Iyi ndiyo nheyo yepamusoro-simba rekubatanidza bolt.
Yakakwirira simba rekubatanidza bhaudhi zvinoenderana nesimba rekukwesha pakati penzvimbo dzekubatanidza dzezvikamu zvinobatanidza kudzivirira kutsvedza. Kuti tive nesimba rekukwesha rakakwana panzvimbo yekubatana, zvinodikanwa kuwedzera simba rekurovedzera uye friction coefficient yenzvimbo dzekusangana dzenhengo. Simba rekubatanidza pakati penhengo rinowanikwa nekushandisa pretension kune mabhoti, saka mabhaudhi anofanira. kuve yakagadzirwa nesimbi yakakwirira-yakasimba, ndicho chikonzero ivo vanonzi ma-high-simba bolt connections.
Musimba repamusoro rebhoti rekubatanidza, 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 sejecha kuputika uye wire brashi yekuchenesa inowanzoshandiswa mukuvaka kubata nzvimbo yekubatana yezvikamu mukati mehutano hwekubatanidza.
