Ikhwalithi ephezulu ye-Isuzu nKr Resear Hub Bolt

1.Izinkinga zokuvuselela ama-bolts anamandla aphezulu

Lapho kukhiqizwa amakhanda amakhanda ama-hexagon socket ngenqubo yesihloko esibandayo, ukwakheka kwangempela kwensimbi kuzothinta ngqo ikhono elakhiwe ngesikhathi sokusebenza kwezihloko ezibandayo. Ngakho-ke, insimbi kufanele ibe neplastiki enhle. Lapho ukwakheka kwamakhemikhali kwensimbi kuhlala njalo, isakhiwo se-metallographic siyisici esiyisisekelo esinquma i-plastiki. Ngokuvamile kuzwakala ukuthi i-pearlite ethambile ethambile ayilungele ukuhola izihloko ezibandayo ngokwakhiwa, kuyilapho i-pearlite enhle ye-spherical ingathuthukisa kakhulu amandla okuphela kwensimbi yensimbi.
Ngensimbi ephakathi kwekhabhoni kanye ne-carbon carbon yensimbi enenombolo enkulu yama-fasteners anamandla aphezulu, ukwenziwa kwe-anneling kwenziwa ngaphambi kwesihloko esibandayo, ukuze uthole i-pearlite eyunifomu neyokuhle ukuze uhlangabezane nezidingo zangempela zokukhiqiza.

I-2.High-Force Sholt Drawing

Inhloso yenqubo yokudweba ukuguqula usayizi wezinto zokwakha, kanti okwesibili ukuthola izakhiwo ezisisekelo zemishini ze-fastener ngokuqina nokuqiniswa. Uma ukusatshalaliswa kwesilinganiso sokuncipha kokudlula ngakunye akufanelekile, kuzodala futhi ukuqhekeka kwe-Torsional ku-wire rod ngentambo ngesikhathi sokudweba. Ngaphezu kwalokho, uma i-lubrication ingalungile ngesikhathi sokudweba, kungadala futhi ukuqhekeka okuguquguqukayo entanjeni yamakhaza edonswayo. Ukuqondiswa kwe-tangent kwenduku yocingo kanye nomdwebo we-wire kufa ngasikhathi sinye lapho induku yocingo ikhishwa ngaphandle kwe-pellet wire love yomdwebo ongeyona ingozi, futhi okuholela ekuhlolweni kwe-unilateral yomdwebo we-wire. Hhayi umfaniswano ngesikhathi senqubo yokuhola amakhaza, ethinta izinga lokuphasa elibandayo.
