Gqoka umthetho wezicathulo zethrekhi
Ngesikhathi sokusebenza okuvamile, iphinikhodi yethrekhi izungeza kancane iye emuva embobeni yephini, okubili kugqoke ngokulinganayo, imbobo yephinikhodi iba nkulu kancane kancane, bese iphinikhodi iba mncane kancane.Uma ukusebenza kungalungile, njengokujika kwesivinini esikhulu, ukuqala kungazelelwe, noma ukungena emanzini anodaka, ukhula, njll. ukuze kuvinjwe izikhonkwane, kuzobangela izinhlangothi ezingakwesokunxele nezingakwesokudla zezicathulo zethrekhi ukuthi zicindezeleke kakhulu futhi ziwohloke, nezikhonkwane zizokhubazeka futhi zigotshwe.Ukuzungezisa, iphinikhodi kanye nembobo yephinikhodi kuba ukungqubuzana okuslayidayo, futhi ingxenye yokungqubuzana inqunyelwe engxenyeni encane yendawo ethintwayo, iphinikhodi igaywa kancane kancane ibe yisimo se-crank, futhi imbobo yephini nayo iba yi-ellipse.
Ukwenyuka kwembobo yephini nakho kubangela ukuthi iphimbo lethrekhi libe lide (iphimbo liyibanga elimaphakathi lemigodi emikhawulweni yomibili yesicathulo sethrekhi), ngakho-ke isicathulo sethrekhi nesondo lokushayela ziyagaya, isicathulo sethrekhi sigqokwa. , namazinyo esondo lokushayela amise okwecele.Ngokwesilinganiso, lapho iphimbo lishintshwa lisuka ku-174 mm liye ku-184 mm, ububanzi bokuvula amazinyo egiya lokushayela buyashintshwa busuka ku-87 mm luye ku-97 mm, kanti i-rolling meshing evamile ibhujiswe ngokuphelele ngalesi sikhathi.
Njengoba i-pitch yezicathulo zethrekhi inwetshiwe, iphinde ibangele ukuthi ama-roller agxume phakathi nokuhamba, okusheshisa ukuguga komzila wezicathulo zethrekhi.Lapho i-subsidence yomgwaqo wezindiza inkulu kune-4 mm, kufanele ilungiswe.
Ukugqokwa kwengxenye yomhlahlandlela wesicathulo sethrekhi ikakhulukazi kubangelwa ukuphambuka kwethrekhi, ukuguqulwa okunamandla kwesicathulo sethrekhi, kanye nokunyakaziswa kwe-axial ngokweqile kwe-roller nesondo lomhlahlandlela.
Izicathulo zethrekhi ezilahliwe ezivamile zigugile kakhulu noma zigqokwe engxenyeni ye-meshing enesondo lokushayela.
Ukulungiswa kwezicathulo zethrekhi
Ukugqokwa kwesicathulo sethrekhi ikakhulukazi kunezingxenye ezimbili: indawo yomjaho kanye nembobo yephini lethrekhi.Kulula kakhulu ukulungisa.Ngemuva kokuthi umgwaqo usugugile, i-groove iyawohloka, futhi lapho ukujula kungeqi ku-2 ~ 3 mm, ingabonakala futhi ilungiswe.Lapho ukugqoka kujulile, imigoqo yensimbi yobukhulu obuhlukahlukene ingagcwaliswa emiseleni ngokwemibandela ethile, bese ihlanganiswa kusuka kuzo zonke izinhlangothi.Imbobo yephini kufanele ibuyiselwe kusayizi wokuqala kanye nendawo emaphakathi yembobo yasekuqaleni ngemva kokugaya.Ngale njongo, sika imbobo yephinikhodi egugile, ufake iphinikhodi yosayizi ojwayelekile, bese uyishisa ifike ku-800 ℃, bese ugoqa unqenqema lwendlebe.Engeza ipuleti lensimbi eliyindilinga ngaphandle kokusikeka bese ulishisela ngokuqinile nge-welding kagesi.Izicathulo zethrekhi ezilungiswe kanjalo zingahlala amashifu angaphezu kuka-100.
Insimbi esikhundleni sezicathulo zethrekhi
Izicathulo zethrekhi zezimoto ezilandelwayo ngokuvamile zenziwe ngensimbi ephezulu ye-manganese enomlando cishe weminyaka eyikhulu wokusetshenziswa.Lokhu kungenxa yokuthi insimbi ephezulu ye-manganese inesici esivelele, okungukuthi, ithola ukuqina komthelela ngaphansi kwesenzo somthwalo womthelela, iyenze ibe ungqimba olungaphezulu oluqinile futhi olungagugi, kuyilapho lusagcina ukuqina nokuqina kwayo kwangaphakathi. ungqimba.Kodwa-ke, insimbi ephezulu ye-manganese isetshenziswa njengesicathulo sethrekhi, esivame ukulinyazwa kusenesikhathi ngenxa yokuqhekeka, amazinyo ahlanekezelwe kanye nokuchezuka ngesikhathi sokusetshenziswa, futhi inokuphila kwesevisi ephansi.Ukuze unqobe lokhu kushiyeka, insimbi ye-30SiMnMoV(Ti) ene-alloy esezingeni eliphansi, esekelwe ezinsizeni zasekhaya futhi kulula ukuyikhiqiza.Isetshenziswe ngempumelelo esikhundleni sensimbi ye-manganese ephezulu ukwenza izicathulo zethrekhi.
izindlela zokucubungula
Ubuchwepheshe bokucubungula isicathulo sethrekhi yephrofayili ngokuvamile: ukusetshenziswa kokusika iphrofayili, ukubhoboza (ukubhoboza), ukwelashwa kokushisa, ukuqondisa, ukudweba nezinye izinqubo;ithrekhi ye-bulldozer iqiniswe eyodwa, futhi umbala wepende jikelele uphuzi;Inezimbambo ezintathu, nombala kapende umnyama.Izinto ezithengwayo zephrofayili ngokuvamile zingu-25MnB, futhi ubulukhuni bokugcina bokwelashwa kokushisa kwento esebenzayo yi-HB364~444.
