Nomoro ea bobeli (8) e emela karo-karolelano ea matla a chai ho ea ho matla a tensile (0.8), ho bolelang hore matla a tlhahiso ke hoo e ka bang 640 MPa. Sehlopha sena se netefatsa ts'ebetso e ts'oanang ho bahlahisi bohle.
Ke hobane'ng ha li-fasteners tse khoele li lokoloha ha nako e ntse e ea?
Ho thetheha ho bakoa haholo ke ho thothomela, meroalo e matla, kapa ho palama baesekele. Matla ana a etsa hore ho thellehe ha microscopic pakeng tsa likhoele le libaka tse beretsoeng, e leng se lebisang tahlehelong ea butle-butle ea preload. Ho sebelisa linate tsa linotlolo, likhomaretsi tse notlelang likhoele, kapa lihlooho tsa serrated flange ho ka fokotsa kotsi ena haholo.
Qetello: Tšebelisano 'moho bakeng sa Precision le Tšepahala
Li-fasteners tse nang le likhoele ke likaroloana tse nyane tse nang le litlamorao tse kholo bakeng sa botsitso ba sebopeho le polokeho ea ts'ebetso. Ho khetha moetsi ea nepahetseng ho akarelletsa ho fetang ho bapisa litheko; e hloka molekane ea utloisisang likaroloana tsa saense ea lintho tse bonahalang, metallurgy, le litekanyetso tsa lefats'e. Boitlamo ba rona ba boenjineri bo nepahetseng, taolo e matla ea boleng, le bokhoni ba tlhahiso ea tloaelo bo netefatsa hore likopano tsa hau li sebetsa ka ts'epahalo tlasa maemo a boima haholo.
Hore na o batla thepa e tloaelehileng bakeng sa kaho e kholo kapa o nts'etsapele litharollo tsa bespoke bakeng sa mechini e tsoetseng pele, sehlopha sa rona se fana ka boiphihlelo ba tekheniki le tšehetso ea thepa e hlokahalang ho tsamaisa phepelo ea hau. Re mema lienjineri, litsebi tsa ho reka thepa, le baokameli ba merero ho ntlafatsa lethathamo la rona le ho feto-fetoha ha thepa.
Bakeng sa lintlha tse qaqileng tsa tekheniki, likopo tsa kh'outu tsa tloaelo, kapa mehlala ea tlhahlobo, ikopanye le sehlopha sa rona sa ts'ehetso ea boenjiniere kajeno. E re re u thuse ho boloka morero oa hau o latelang ka kholiseho le ka nepo.
