Muyero wekuongorora wemabhaudhi matayi ndewekuti: mabhaudhi etayi akazara uye haana kusunungurwa.
Bhaudhi imhando yefastener ine musoro nescrew (cylinder ine shinda dzekunze), inoda kubatanidza nenzungu kuti isunge uye kubatanidza zvikamu zviviri nemaburi.Mechanical parts, cylindrical threaded fasteners ane nzungu.Yakakamurwa kuva mabhoti akajairwa uye akakwirira-simba mabhoti, uye yakakwirira-simba mabhoti mabhoti ane simba-akakwirira, ayo ari echikamu chechiyero.Chinhu chinonyanya kukosha chepamusoro-simba mabhoti ndechokuti inongogumira kune imwe nguva kushandiswa, inowanzoshandiswa pakubatanidza, uye kushandiswa kwekudzokorora kunorambidzwa zvachose.Maererano nemamiriro ekudzvinyirira, yakakamurwa kuva: friction type uye pressure type;maererano tekinoroji yekuvaka, yakakamurwa kuita: torsional shear mhando yakakwirira-simba mabhaudhi uye yakakura hexagonal yakakwirira-simba mabhoti.
Bolt kuongorora zvinhu:
Kuonekwa kwe torque, kuona torque, kuona kuoma, anti-slip coefficient kuona, torque inoshanda, kukiya kuita, torque coefficient, fasting axial force, friction coefficient, anti-slip coefficient, screw-in test, gasket elasticity, kuoma, hydrogen embrittlement Test, kubata kumeso, kupisa, gomba reming bvunzo, kukotama, (rimwe divi, kaviri-side) shear bvunzo, pendulum kukanganisa, kuzorora kushushikana, kupisa kwakanyanya, kutsungirira bvunzo, lateral vibration, kuneta bvunzo, metallographic analysis ( microstructure analysis, microhardness test. ), bvunzo yekuumbwa kwemakemikari, nezvimwe.
