Lolu hlobo lwe-shaft lunokusebenza okuhle kwemishini. Ekusetshenzisweni okusebenzayo, ayinayo i-porosity noma ezinye iziphambeko, ngakho-ke ayinayo kuphela isiqiniseko sokubukeka okuhle, kodwa futhi inokusebenza okuhle kakhulu.
Kunezinhlobo eziningi zama-gear shaft forgings. Izinto zokwakha ezisetshenziswa kakhulu zifaka i-40Cr, 42CrMo, 20CrMnMo, kanye ne-20CrMnTi. I-42CrMo kanye ne-40Cr amagiya omgunyathi ngokuvamile amagiya amakhulu embonini yokuphakamisa, kuyilapho i-20CrMn molybdenum kanye ne-20CrMnTi isetshenziswa kakhulu ukwenza amagiya emishini yokudlulisela. Amagiya amaningi adinga amagiya okuphakamisa. Ngo-38-42HRC, ubulukhuni bokwelashwa kwamagiya kuzuze ukusebenza okuhle. Ngenxa yokuqina okuhle kakhulu kokwelashwa kokushisa kokwangaphambili, ukuqina kwe-42CrMo kungcono kakhulu kunalokho kwe-40Cr, okuhlobene eduze nezinto zayo. Ngokufanayo, ngobulukhuni obufanayo, amandla aseduze kakhulu. Amandla aqinile we-40Cr yi-6 ~; Amandla aqinile we-42CrMo ngu-110kg/mm2, futhi amandla okukhiqiza angu-95kg/mm2. Ukusebenza kungcono kakhulu kune-40Cr.
I-40Cr impahla inokuqina okuhle.
Ukucisha amanzi kungaba lukhuni kube ububanzi obungamamilimitha angu-28-60, kuyilapho ukucisha uwoyela kungaqina kube ububanzi obungamamilimitha angu-15-40. Ngemuva kokucisha kanye nokushisa, okokusebenza kukhombisa izici zemishini ezibanzi kakhulu, ukuzwela kwenotshi ephansi, kanye nokuqina komthelela wezinga lokushisa eliphansi. I-40Cr gear forgings imvamisa ingaphansi kokucisha imvamisa ephezulu noma ukwelashwa kwe-nitriding ngemuva kokucisha kanye nokushisa. Lapho ubulukhuni bungu-174-229HBS, bunokusebenziseka okuhle, ngokusebenza okuhlobene okungama-60%. Okuqukethwe kwekhabhoni ye-40Cr yezinto zokwakha kugcinwa cishe ku-0.40%, ngaleyo ndlela kuqinisekisa inhlanganisela enhle yamandla nokuqina kwensimbi. Engeza isici se-Cr. (Cr, Fe) 3C. Izinga lokushisa lokuqala lokuqamba lamagiya angu-40Cr liyi-1100 ~ 1150 ℃, futhi izinga lokushisa lokubumba lingu-800 ℃. Ngemuva kokubumba, ubukhulu obungaphezu kwamamilimitha angama-60 budinga ukupholisa kancane.
Umkhiqizi we-gear shaft ukhumbuza ukuthi i-material ye-shaft forgings kufanele ihlangabezane nezidingo zezimo zokusebenza. Lapho ukhetha izinto zokwakha igiya, into yokuqala okufanele icatshangelwe yizidingo zezimo zokusebenza. Insimbi ye-alloy ivamise ukusetshenziselwa ukukhiqiza amagiya asebenza ngaphansi kwesivinini esikhulu, esindayo, nemithwalo enomthelela. Kudingeka ukuthembeka okuphezulu, futhi kubalulekile ukukhetha insimbi ye-alloy enezakhiwo eziphezulu zemishini. Uma usayizi wegiya udingeka ukuthi ube mncane ngangokunokwenzeka, insimbi enamandla amakhulu enengxubevange enokwelashwa kokuqina kwendawo kufanele isetshenziswe. Ukuhanjiswa kwegiya emishinini yezimayini kuvame ukuba namandla aphezulu, isivinini esiphansi sokusebenza, nothuli oluphezulu endaweni ezungezile. Ngakho-ke, izinto ezifana nensimbi ecijile noma insimbi ekhonjiwe zivame ukukhethwa, kodwa ukudluliswa komsindo kuncane, futhi imvamisa yokusebenza kwemishini yasehhovisi iphansi kakhulu. Lolu hlobo lwe-shaft lunokusebenza okuhle kwemishini. Ekusetshenzisweni okusebenzayo, ayinayo i-porosity noma ezinye iziphambeko, ngakho-ke ayinayo kuphela isiqiniseko sokubukeka okuhle, kodwa futhi inokusebenza okuhle kakhulu.
