Izinyo ingenye izingxenye ezibalulekile phezu excavator, lokwela ibhakede lifana amazinyo omuntu, futhi egqoke izingxenye, yakhiwa izinyo nezinyo tip inhlanganisela dipper amazinyo, kokubili by pin shaft link.Ngenxa izinyo ibhakede ukugqoka ukwehluleka ingxenye izinyo, inqobo nje esikhundleni nge tip.
Ngenxa yethonya lenkinga yezezimali, izwe lethu likhulisa ngenkuthalo isidingo sasekhaya, lenza imakethe yasekhaya yamazinyo ebhakede ibe nomphumela omuhle, yenza abakhiqizi abaningi bezinyo zamabhakede banethemba lemakethe yasekhaya!
A: Ukuhlaziywa kokucindezeleka kwezinyo lebhakede zithintana nazo ngesigaba sokumba, ezigabeni zokusebenza ezihlukene eziphelele ngesikhathi sokumba amandla ahlukile.Ingxenye yezinyo iqala ukuthintana nendawo ebonakalayo, ngenxa yokushesha, ingxenye yezinyo lebhakede isuka kokunamandla.Uma amandla isivuno ephansi of ibhakede izinyo, uzoveza deformation plastic in tip.Kanye nokwanda kokujula kwezimayini, ukusabalalisa kokucindezeleka kwezinyo lebhakede kuzoshintsha.Lapho izinyo ebhakedeni ukusika impahla, ukunyakaza isihlobo kwenzeka, izinyo ibhakede kanye impahla umkhiqizo omkhulu kakhulu extrusion ingcindezi ebusweni, ngaleyo ndlela izinyo ibhakede ubuso futhi akhiqize ukungqubuzana emikhulu phakathi materials.Uma impahla iyitshe eliqinile, ukhonkolo, njll., amandla okungqubuzana azoba mkhulu.Imiphumela yale nqubo izikhathi ezimbalwa nangaphezulu kwezinyo lebhakede libhekene nokuguga, ngaleyo ndlela ikhiqize imisele emikhulu ejulile.Ukwakheka kwamazinyo dipper kuwumphumela omuhle ubude yokuphila service of the amazinyo dipper, khetha izinyo ibhakede, Yebo, idiot ngokuqapha more ithengiswe ibhakede izinyo lakhe ibhakede izinyo Ngabuye wasebenzisa, umphumela muhle!Ubuso emva kwengcindezi yokusebenza ubuso ngokusobala buphakeme kunakuqala, ngaphambi kokusebenza ubuso ukuguga okukhulu kanye izinyembezi, futhi anganquma ingcindezi omuhle kanye friction amandla iyona izindlela ezinkulu ukwehluleka of ibhakede izinyo izici zangaphandle mechanical, idlala indima enkulu inqubo umkhiqizo.
2: Ukuhlaziywa kwenqubo yamasampula amabili asuka kulelo nalelo ngaphambi nangemuva kobuso obusebenzayo, ukuhlolwa kobulukhuni obushelelezi.Kutholwe kwisampula efanayo umehluko ubulukhuni mkhulu kakhulu, isahlulelo sokuqala alilingani.Isampuli yokugaya, ukupholishwa, ukunamathisela, ithole ukuthi isampula ngayinye emingceleni esobala, ivele iklelise izingxenye ezihlukene.Kusukela ekubukeni kwe-macroscopic, okumpunga okuphaphathekile, okuzungeze ingxenye ephakathi, enombala omnyama kubonisa ukuthi into okungenzeka isethwe ukusakaza, phezulu, izungezwe izingxenye kufanele futhi zibe yizicucu.Kwa-HRS – 150 digital rockwell hardness tester kanye ne-MHV – 2000 digital display microhardness mitha kulayini nhlangothi zombili zokuhlolwa kokuqina, ngokulandelana, kubonise umehluko omkhulu (bheka ithebula 1).Ngokusebenzisa ukuhlaziya okungenhla kwaqinisekisa ukuthi amazinyo ediphu isethwe ucezu lwesakhiwo.Vala ezinye zazo ziyisiqephu esimisiwe, ingxenye yi-matrix ezungezile.Ukwakheka kokubili close, ezifana Cr, Mn, Si izakhi ingxubevange, izakhi main ingxubevange (mass ingxenyenamba, %) ka 0.38 C, 0.91 0.83 0.83 Mn, Cr, Si.Izakhiwo zemishini yezinto zensimbi zincike ekubunjweni kwezinto ezibonakalayo kanye nenqubo yokwelapha ukushisa.Umehluko phakathi kokwakheka okufanayo nobulukhuni bamazinyo ebhakede ngaphandle kokwelashwa okushisa okusetshenziswa ngemva kokuphonswa.Inhlangano ehambisana nalokhu kubuka nayo iyalifakazela leli phuzu.
