Olu hlobo lwe-shaft lunokusebenza kakuhle komatshini. Kwizicelo ezisebenzayo, ayinayo nayiphi na i-porosity okanye ezinye iziphene, ngoko ayinayo isiqinisekiso senkangeleko esihle kuphela, kodwa inokusebenza okugqwesileyo.
Kukho iintlobo ezininzi ze-gear shaft forgings. Izinto ezisetyenziswa ngokuqhelekileyo izixhobo zokubumba izixhobo ziquka i-40Cr, i-42CrMo, i-20CrMnMo, kunye ne-20CrMnTi. I-42CrMo kunye ne-40Cr iigiya zomgunyathi ubukhulu becala zezona zixhobo zinkulu kushishino lokunyusa, ngelixa i-20CrMn molybdenum kunye ne-20CrMnTi zisetyenziswa ikakhulu ukwenza iigiya koomatshini bokuhambisa. Uninzi lweegiya zifuna iigiya zokunyusa. Kwi-38-42HRC, ubulukhuni bokunyangwa kobushushu beegiya bufezekise ukusebenza kakuhle. Ngenxa yokuqina kobushushu obugqwesileyo bokuqala, ubunzima be-42CrMo bungcono kakhulu kune-40Cr, ehambelana ngokusondeleyo nezinto zayo. Ngokufanayo, ubunzima obufanayo, amandla asondele kakhulu. Amandla e-tensile ye-40Cr yi-6 ~; Amandla e-tensile ye-42CrMo yi-110kg / mm2, kwaye amandla emveliso yi-95kg / mm2. Ukusebenza kungcono kakhulu kune-40Cr.
Izinto ze-40Cr zinobunzima obuhle.
Ukucinywa kwamanzi kunokuba lukhuni ukuya kububanzi obuyi-28-60 millimeters, ngelixa ukucinywa kweoli kunokuqina ukuya kwi-15-40 millimeters. Emva kokucima kunye nokufudumeza, izinto ezibonakalayo zibonisa iimpawu ezibalaseleyo zoomatshini, uvakalelo oluphantsi lwenotshi, kunye nokuqina kwefuthe lobushushu obuphantsi. I-40Cr i-forging yegiya ihlala iphantsi kokucinywa kwe-high-frequency quenching okanye unyango lwe-nitriding emva kokucima kunye nokuvutha. Xa ubunzima buyi-174-229HBS, inokusebenza kakuhle, kunye ne-machinability yesihlobo se-60%. Umxholo wekhabhoni we-40Cr izinto zokubunjwa kwezinto zigcinwa malunga ne-0.40%, ngaloo ndlela uqinisekisa ukudibanisa okuhle kwamandla kunye nokuqina kwentsimbi. Yongeza isiqalelo se-Cr. (Cr, Fe) 3C. Ubushushu bokuqala bokubunjwa be-40Cr bobunjwa begiya yi-1100 ~ 1150 ℃, kwaye ubushushu bokubumba yi-800 ℃. Emva kokupholisa, imilinganiselo engaphezulu kwe-60 millimeters ifuna ukupholisa okucothayo.
Umenzi we-shaft we-gear ukhumbuza ukuba izinto ezifakwe kwi-shaft forgings kufuneka ziqale ukuhlangabezana neemfuno zeemeko zokusebenza. Xa ukhetha izixhobo zokubumba izixhobo, into yokuqala ekufuneka uyiqwalasele ziimfuno zeemeko zokusebenza. Intsimbi ye-alloy iqhele ukusetyenziselwa ukuvelisa i-gear forgings esebenza phantsi kwesantya esiphezulu, esinzima, kunye nemithwalo yempembelelo. Ukuthembeka okuphezulu kuyafuneka, kwaye kubalulekile ukukhetha insimbi ye-alloy eneempawu eziphezulu zemishini. Ukuba ubungakanani begiya bufunekayo ukuba bube buncinci ngokusemandleni, isinyithi esine-alloy high-high-high-high-high-harding treatment kufuneka sisetyenziswe. Ukuhanjiswa kwegiya koomatshini bemigodi kuhlala kunamandla aphezulu, isantya esisezantsi sokusebenza, kunye nomxholo wothuli oluphezulu kwindawo engqongileyo. Ke ngoko, izinto ezinje ngentsimbi ephosiweyo okanye intsimbi ephosiweyo zihlala zikhethwa, kodwa ukuhanjiswa kwengxolo kuncinci, kwaye ukusebenza rhoqo koomatshini beofisi kuncinci. Olu hlobo lwe-shaft lunokusebenza kakuhle komatshini. Kwizicelo ezisebenzayo, ayinayo nayiphi na i-porosity okanye ezinye iziphene, ngoko ayinayo isiqinisekiso senkangeleko esihle kuphela, kodwa inokusebenza okugqwesileyo.
