Hex Structural Bolt / Heavy Hex Bolt

Ngatitangei kunzwisisa kuti chii chinonzi simbi chimiro chepamusoro-simba bolt.Inowanzo kugadzirwa nesimbi inopisa-yakasimba-yakasimba (35CrMo\35 carbon steel material, nezvimwewo), iyo inogona kukamurwa kuva 8.8 mamakisi maererano negiredhi rekuita.Giredhi 10.9, kusiyana nemabhaudhi akajairwa, mabhaudhi anofanira kunge ari pamusoro pegiredhi 8.8.Hapana chikonzero chekuisa mberi zvinodiwa zvesimbi giredhi uye simbi giredhi pakusarudza.Friction majoini anoshandiswa zvakanyanya musimbi chimiro engineering.

Simbi chimiro chepamusoro-simba mabhaudhi anogona kukamurwa kuita marudzi maviri: friction type yekubatanidza uye kudzvanywa mhando yekubatanidza zvinoenderana nemaitiro esimba.Kubatana kwepamusoro kwepamusoro-simba rebhoti-inotakura mhando yekubatanidza inongoda kuva ngura-uchapupu.Nekudaro, friction type yakakwira-simba mabhaudhi ane zvakanakira kubatana kwakasimba, simba rakanaka, kuramba kuneta, uye akakodzera kutakura mitoro ine simba, asi nzvimbo yekubatanidza inoda kurapwa nefriction surface, kazhinji nejecha, sandblasting, yozoputirwa ne inorganic zinc-rich pendi.

Pamusana pekusiyana kwekugadzirwa kwebhoti uye nzira dzekuvaka, mabhoti akakwirira-akasimba ezvivako zvesimbi anogona kugoverwa mumhando mbiri: hombe hexagonal musoro high-simba mabhoti uye torsional shear mhando yepamusoro-simba mabhoti.Iyo yakakura hex musoro mhando yakafanana neyakajairika hex musoro mabhaudhi.Musoro webhaudhi wechigero chekudhonzera wakafanana nemusoro werivet, asi iyo yakarukwa yekupedzisira yechigero chetorsion ine torx collet uye annular groove kudzora kuomesa torque.Musiyano uyu unoda kutariswa.

Iyo bolt yekubatanidza pair inosanganisira zvikamu zvitatu: bhaudhi, nati uye washer.Chimiro uye kurongeka kwezvinodiwa zve-high-simba mabhaudhi zvakafanana neaya akajairika mabhoti.Zvadaro inofanira kushandiswa maererano nezvinodiwa.Mabhaudhi akasimba chete egiredhi 8.8 anogona kushandiswa kumisoro mikuru yehexagon, uye mabhaudhi akasimba egiredhi 10.9 anogona kushandiswa chete kune torsion shear type mabhaudhi akasimba.

Iko kurongedzerwa kwepamusoro-kusimba mabhoti muzvigadzirwa zvesimbi kunowanikwa nekusimbisa nzungu.Iyo preload inowanzodzorwa nekumonyorora kubva bhaudhi muswe uchishandisa torque nzira, angle nzira kana Torx nzira.

Parizvino pane yakakosha wrench inoratidza torque.Uchishandisa hukama pakati peiyo yakayerwa torque uye bhaudhi tension, torque inoiswa kuti iwane inodiwa pamusoro-tension kukosha.

Nzira yekona Nzira yekona yakakamurwa kuita matanho maviri, imwe ndiyo yekutanga screwing, uye imwe ndiyo yekupedzisira screwing.Kuti zvinyatsojeka, kusungirirwa kwekutanga kunowanzoitwa nemushandi achishandisa wrench yakajairwa kuita kuti zvikamu zvakabatana zvakanyatsoenderana, uye kusungirirwa kwekupedzisira kunotanga kubva panzvimbo yekutanga yekusimbisa, uye kona yekupedzisira yekusimbisa inobva pahupamhi hwebhoti. uye ukobvu hweplate stack.Shandisa chipanera chakasimba kutendeutsa nati uye nekuipa kune yakafanotemerwa kona kukosha, uye tension yebhaudhi inogona kusvika kune inodiwa preload kukosha.Kuti udzivise torque coefficient ye-high-simba mabhoti kubva pakuchinja nekuda kwesimba rekunze kwezvakatipoteredza, yekutanga uye yekupedzisira kuomesa kunofanirwa kupedzwa mukati mezuva rimwe chete.

Mamiriro ekushungurudzika kwe torsional shear high-simba mabhoti akafanana neaya epamusoro-simba mabhoti, kunze kwekuti nzira yekushandisa pretension ndeyekudzora kukosha kwekunyengedza nekumonyorora chikamu pakucheka.Kumonyorora kwebhaudhi.

Iyo friction type yakakwira-simba bhaudhi yekubatanidza inotsamira zvachose pakupokana pakati pezvinhu zvakabatana kuti zvitumire simba, uye friction kuramba haisiriyo chete pre-kusimbisa simba rebhaudhi, asiwo anti-skid pfuma ye friction surface. zvakatemwa nepamusoro pekurapa.Izvo zvinhu zvekubatanidza chinhu uye nzvimbo yayo yekubata.coefficient.

Mushure mekuiverenga, ndinotenda kuti munhu wese akanyatsonzwisisa, apo mabhoti ane simba-akakwirira anofanira kushandiswa, uye kushanda kwakarurama uye kusimbisa.
