I-crankshaft yeyona ndawo ijikelezayo ye-injini kunye neyona ndawo ibalulekileyo ye-injini. Ngokwamandla kunye nomthwalo owuthweleyo, i-crankshaft idinga ukuba namandla okwaneleyo kunye nokuqina, kwaye umphezulu wejenali kufuneka ungagugi, usebenze ngokufanayo, kwaye ube nokulinganisela okulungileyo.

Unyango lwe-Nitriding

Ngenxa yokubaluleka kwe-crankshaft, unyango lobushushu lwe-crankshaft luneemfuno ezingqongqo kakhulu zokuguqulwa. Kwiicrankshafts eziveliswe ngobuninzi, unyango lobushushu be-ion nitriding lusetyenziswa ngokubanzi ukuphucula umgangatho wemveliso. Kwintsimbi yekhabhoni okanye intsimbi ephosiweyo okanye intsimbi ephantsi, abantu bahlala besebenzisa i-ion soft nitriding (ikhabhoni yobushushu obuphantsi, i-nitrocarburizing) ubuchwepheshe. Inani elikhulu lezenzo libonise ukuba ubunzima kunye nokungena kwe-nitrided layer kunobudlelwane obugqithisileyo kunye nobushushu, ixesha kunye nokugxila. Uluhlu lokulawula ubushushu be-ion nitriding ethambileyo kufuneka ibe ngaphezulu kwe-540 ℃ kwaye ibe ngaphantsi kweqondo lobushushu lokuguga, kwaye isantya esifanelekileyo sokufudumeza kufuneka sikhethwe ngokweemfuno ezithile zamalungu.

Unyango olushushu lwe-ion nitriding lune-deformation encinci, enokuqinisekisa ngokufanelekileyo ukuguqulwa. Uluhlu olumhlophe kunye noluqaqambileyo kunye noluhlu olugqithisiweyo lufana, ubukhulu boluhlu olugqithisiweyo buyalawuleka, umjikelezo wonyango ufutshane, kwaye ukusebenza kakuhle kuphezulu. Okwangoku, i-ion nitriding furnace eveliswe yinkampani yethu ifezekise imveliso eninzi yeecrankshafts, kwaye umgangatho we-nitriding uphezulu, owamkelwa kakuhle ngabathengi.
