Ngemuva kokuthi i-bearing isebenze isikhathi eside, akunakugwenywa ukuthi kuzoba nesidingo sokulungiswa noma ukulimala nokushintshwa. Ezinsukwini zokuqala zokuthuthukiswa kwemboni yemishini, kwakudingeka ukuthi kudume kakhulu ulwazi lochwepheshe kanye nokuqwashisa ngezinqubo zokusebenza eziphephile. Namuhla, sizokhuluma kuphela nge-disassembly of bearings.
Kujwayelekile ukuthi abanye abantu bahlukanise ama-bearings ngokushesha ngaphandle kokuwahlola kahle. Nakuba lokhu kungase kubonakale kusebenza kahle, kubalulekile ukucabangela ukuthi akuwona wonke umonakalo obonakalayo ebusweni bokuthwala. Kungase kube nomonakalo ngaphakathi ongabonakali. Ngaphezu kwalokho, ukuthwala insimbi iqinile futhi i-brittle, okusho ukuthi ingaqhekeka ngaphansi kwesisindo sayo, okuholela emiphumeleni eyinhlekelele.
Kubalulekile ukulandela izinqubo zesayensi futhi usebenzise amathuluzi afanele lapho ufaka noma uqaqa i-bearing ukugwema noma yimuphi umonakalo ongase ube khona. Ukuhlukaniswa okunembile nokusheshayo kwama-bearings kudinga amakhono nolwazi, okuxoxwa ngakho kabanzi kulesi sihloko.
Ukuphepha kuqala
Ukuphepha kufanele ngaso sonke isikhathi kube yinto ehamba phambili kunoma yikuphi ukusebenza, okuhlanganisa ukuqaqa. Ama-Bearings cishe azoguga ngasekupheleni kweminyaka yawo yokuphila. Ezimweni ezinjalo, uma inqubo ye-disassembly ingenziwanga ngendlela efanele futhi kusetshenziswe inani eliningi lamandla angaphandle, kunethuba eliphezulu lokuhlukana kwe-bearing. Lokhu kungabangela izingcezu zensimbi ukuba zindize, kube yingozi enkulu yokuphepha. Ngakho-ke, kunconywa kakhulu ukusebenzisa ingubo yokuzivikela ngenkathi uhlakaza i-bearing ukuqinisekisa ukusebenza okuphephile.
Ukuhlukaniswa kwe-bearing disassembly
Uma izilinganiso zokusekela zenzelwe kahle, ama-bearings ane-clearance fits angasuswa ngokuqondisa ama-bearings, inqobo nje uma engakhubazekile noma egqwalile ngenxa yokusetshenziswa ngokweqile futhi anamathele ezingxenyeni ezihambisanayo. Ukuhlakazwa okunengqondo kwama-bearings ngaphansi kwezimo zokufaneleka kokuphazamiseka kuwumnyombo wokuthwala ubuchwepheshe be-disassembly. Ukulingana kokuphazamiseka kwe-Bearing kuhlukaniswe ngezinhlobo ezimbili: ukuphazamiseka kwendandatho yangaphakathi kanye nokuphazamiseka kwendandatho yangaphandle. Ezigabeni ezilandelayo, sizoxoxa ngalezi zinhlobo ezimbili ngokwehlukana.
1. Ukuphazamiseka kweringi yangaphakathi yeringi kanye nokulingana kweringi yangaphandle
1. I-cylindrical shaft
Ukuzalanisa i-disassembly kudinga ukusetshenziswa kwamathuluzi athile. I-puller ivame ukusetshenziselwa ama-bearings amancane. Laba abadonsayo bafika ngezinhlobo ezimbili - i-two-claw kanye ne-three-claw, kokubili okungafakwa ku-threaded noma i-hydraulic.
Ithuluzi elivamile umshini wokudonsa intambo, osebenza ngokuqondanisa isikulufu esimaphakathi nembobo emaphakathi ye-shaft, ukusebenzisa ugrisi embobeni emaphakathi ye-shaft, bese uhuka ihhuku ekugcineni kobuso beringi yangaphakathi yebheringi. Uma ihhuku isimi endaweni, kusetshenziswa isikrufu ukujika induku ephakathi, bese ikhipha i-bearing.
Ngakolunye uhlangothi, i-hydraulic puller isebenzisa i-hydraulic device esikhundleni sentambo. Uma ucindezelwa, i-piston phakathi nendawo iyanwebeka, futhi i-bearing ikhishwe ngokuqhubekayo. Iyashesha kunomshini wokudonsa intambo ovamile, futhi idivayisi ye-hydraulic ingahlehla ngokushesha.
Kwezinye izimo, asikho isikhala sezinzipho zomdonsi wendabuko phakathi kobuso bokuphela kweringi yangaphakathi yokuthwala nezinye izakhi. Ezimweni ezinjalo, i-splint enezicucu ezimbili ingasetshenziswa. Ungakhetha usayizi ofanele we-splint futhi uyihlukanise ngokuhlukana ngokusebenzisa ukucindezela. Izingxenye ze-plywood zingenziwa zibe mncane ukuze zikwazi ukungena ezindaweni ezincane.
Uma iqoqo elikhudlwana lama-bearings anosayizi omncane lidinga ukuhlakazwa, umshini wokuhlanganisa amanzi osheshayo ungasetshenziswa (njengoba kukhonjisiwe ngezansi).
▲Hqa ngokushesha idivayisi esebenza nge-hydraulic
Ukuze kuhlakazwe ama-bearings abalulekile kuma-axles emoto kaloliwe, kukhona nemishini ekhethekile yokuhlakaza ephathwayo.
▲Idivayisi yokuqaqa yeselula
Uma ubukhulu be-bearing bukhulu, kuzodingeka amandla amaningi ukuyiqaqa. Ezimweni ezinjalo, abadonsi abajwayelekile ngeke basebenze, futhi umuntu uzodinga ukuklama amathuluzi akhethekile wokuqaqa. Ukuze ulinganise amandla amancane adingekayo ekuhlakazeni, ungabhekisela kumandla okufaka adingekayo ukuze kube khona ukunqoba ukulingana kokuphazamiseka. Ifomula yokubala imi kanje:
F=0.5 *π *u*W*δ* E*(1-(d/d0)2)
F = Amandla (N)
μ = i-coefficient yokungqubuzana phakathi kweringi yangaphakathi ne-shaft, ngokuvamile ezungeze u-0.2
W = ububanzi bendandatho yangaphakathi (m)
δ = isilinganiso sokuphazamiseka (m)
E = Imoduli yabancane 2.07×1011 (Pa)
d = elinobubanzi obungaphakathi (mm)
d0=ububanzi obuphakathi bomzila wangaphandle weringi yangaphakathi (mm)
π= 3.14
Lapho amandla adingekayo ukuze ahlakaze i-bearing maningi kakhulu ezindleleni ezivamile kanye nezingozi ezilimaza i-bearing, imbobo kawoyela ngokuvamile iklanywa ekupheleni kwe-shaft. Le mbobo kawoyela idlulela endaweni yokuthwala bese ingena endaweni ye-shaft ngokukhanya. I-groove ye-annular iyengezwa, futhi ipompo ye-hydraulic isetshenziselwa ukucindezela ukuphela kwe-shaft ukuze kwandiswe indandatho yangaphakathi ngesikhathi sokuqaqa, kunciphisa amandla adingekayo ukuze kuhlakazwe.
Uma ukuthwala kukhulu kakhulu ukuba kungahlakazwa ngokudonsa kanzima okulula, khona-ke indlela yokushisa yokushisa idinga ukusetshenziswa. Ngale ndlela, amathuluzi aphelele afana nama-jack, ama-gauge obude, ama-spreaders, njll, adinga ukulungiswa ukuze asebenze. Le ndlela ihlanganisa ukushisisa ikhoyili ngqo emgwaqeni womjaho weringi yangaphakathi ukuze uyinwebe, okwenza kube lula ukuqaqa i-bheringi. Le ndlela efanayo yokushisa ingasetshenziswa futhi kuma-cylindrical bearings anama-roller ahlukene. Ngokusebenzisa le ndlela, ukuthwala kungahlakazwa ngaphandle kokudala umonakalo.
▲Indlela yokuhlukanisa ukushisisa
2. Umphini ocijile
Uma uqaqa i-bearing ecijile, ubuso obukhulu besiphetho seringi yangaphakathi budinga ukushisisa njengoba indawo yakhona inkulu kakhulu kunobunye ubuso bokuphela. I-coil medium frequency induction heater eguquguqukayo isetshenziselwa ukushisisa iringi yangaphakathi ngokushesha, idale umehluko wezinga lokushisa nge-shaft futhi ivumele ukuhlakazeka. Njengoba ama-tapered bearings asetshenziswa ngababili, ngemva kokukhipha indandatho eyodwa yangaphakathi, enye nakanjani izovezwa ukushisa. Uma indawo enkulu yokugcina ingakwazi ukushiswa, ikheji kufanele libhujiswe, ama-roller asuswe, futhi umzimba wendandatho yangaphakathi uvezwe. Ikhoyili ingabe isibekwa ngqo emgwaqeni womjaho ukuze kufudunyezwe.
▲ I-heater eguquguqukayo yekhoyili ephakathi nendawo
Ukushisa kokushisa kwe-heater akufanele kudlule ama-degrees Celsius angu-120 ngoba ukuthwala i-disassembly kudinga umehluko wokushisa osheshayo kanye nenqubo yokusebenza, hhayi izinga lokushisa. Uma izinga lokushisa elizungezile liphakeme kakhulu, ukuphazamiseka kukhulu kakhulu, futhi umehluko wokushisa akwanele, iqhwa elomile (i-carbon dioxide eqinile) lingasetshenziswa njengendlela yokusiza. Iqhwa elomile lingabekwa odongeni lwangaphakathi lwe-shaft engenalutho ukuze kuncishiswe ngokushesha izinga lokushisa le-shaft (imvamisa usayizi omkhulu kangaka.izingxenye ze-cnc), ngaleyo ndlela kwandisa umehluko wezinga lokushisa.
Ukuze kuhlakazwe ama-bearings ane-tapered bore, ungalisusi ngokuphelele i-clamping nut noma umshini ekupheleni kwe-shaft ngaphambi kokuhlakazeka. Yixegise kuphela ukuze ugweme ukuthwala izingozi eziwayo.
Ukuhlakazwa kwama-shaft ama-tapered amakhulu kudinga ukusetshenziswa kwezimbobo zikawoyela ezihlakazekayo. Ukuthatha i-rolling mill enemigqa emine ene-tapered TQIT ene-tapered bore njengesibonelo, iringi yangaphakathi yokuthwala ihlukaniswe izingxenye ezintathu: izindandatho ezimbili zangaphakathi ezinomugqa owodwa kanye nendandatho ekabili yangaphakathi phakathi. Kunezimbobo ezintathu zikawoyela ekugcineni komqulu, ezihambisana namamaki 1 no-2,3, lapho enye ihambisana nendandatho yangaphakathi yangaphandle, ezimbili zihambisana nendandatho yangaphakathi ekabili ephakathi, futhi ezintathu zihambisana nendandatho yangaphakathi engaphakathi nengaphakathi. ububanzi obukhulu kakhulu. Lapho uqaqa, qaqa ngokulandelana izinombolo ze-serial bese ucindezela izimbobo 1, 2, no-3, ngokulandelana. Ngemuva kokuthi konke sekuqediwe, lapho ukuthwala kungaphakanyiswa ngenkathi ushayela, susa indandatho ye-hinge ekupheleni kwe-shaft futhi uhlukanise i-bearing.
Uma ukuthwala kuzophinde kusetshenziswe ngemva kokuhlakazwa, amandla asetshenziswa ngesikhathi sokuqaqa akufanele adluliselwe ngezinto ezigoqayo. Kuma-bearings ahlukanisekayo, iringi yokuthwala, kanye ne-rolling element cage assembly, ingahlakazwa ngokuhlukana kwenye indandatho yokuthwala. Lapho uhlukanisa ama-bearings angahlukanisiwe, kufanele uqale ususe izindandatho ezithwala ngokulingana kwemvume. Ukuze uhlukanise ama-bearings ngokulingana kokuphazamiseka, udinga ukusebenzisa amathuluzi ahlukene ngokuya ngohlobo lwawo, usayizi, nendlela efanelekile.
