Ukunakekelwa kwe-Idler
Ama-idlers kanye nama-idler bearings yizingxenye ezibalulekile zomshini wokusika ucingo.Ukunemba okuhle, isiphetho esihle nokusebenza kahle okuphezulu konke kuncike kumavila abhalansile, alula futhi anembile.
Ukugcinwa kwesondo lomhlahlandlela kanye nokuthwala kufanele kuqale ekufakweni.Kudingeka ukuthi amathuluzi asetshenzisiwe kanye nendawo yokuhlangana kufanele ihlanzeke, futhi indawo yokusebenza yokuthwala akufanele ilethwe ekungcoleni.Susa konke ukufakwa okuqinile, ukungqongqoza kanye nokucindezela okuqinile akuvunyelwe kuyo yonke inqubo.Ukuguqulwa okubangelwa yilokhu kufakwa kuzobhubhisa ngokuphelele ukunemba kwangempela kwesondo lomhlahlandlela nokuthwala.
Ukunakwa okukhethekile kufanele kukhokhwe ku-pulley yomhlahlandlela esetshenziswayo.Uma ukuzungezisa okuthwele kungaguquguquki ngokwanele noma kukhona into yangaphandle evimbela i-pulley yomhlahlandlela, ucingo luzomiswa emseleni omise okwe-V futhi ukunemba komumo we-groove emise okwe-V kuzolahleka ngokushesha.Indawo yokusebenza ye-bearing ayikwazi ukungena emanzini, futhi indle equkethe ukungcola ingagaya ukuthwala ngokushesha okukhulu.Okubaluleke nakakhulu ukuthi i-aber kanye nesondo eliqondisayo akuvunyelwe ukugeleza ku-curse.Uma ukunikezwa kwamandla kwefrikhwensi ephezulu kusetshenziswa njengeshaneli, ukugqwala okusheshayo kuzoba kubi kakhulu.Amanzi angcolile, ikakhulukazi okusika i-aluminium, kufanele ashintshwe ngesikhathi.
Amathuluzi omshini asebenze amahora amaningi
Qinisekisa ukuthi usula phansi izimpande ze-idler pulley kanye nezindlu ezithwele ukuze ususe noma yikuphi udaka oluvalekile.Futhi uphonsa inani elincane lamafutha, vumela ucingo lugijime ngesivinini esigcwele imizuzu embalwa, ukuze amafutha awile kanye nokungcola kuphonswe ndawonye, bese uphonsa emafutheni, njalonjalo izikhathi eziningana.Isondo elingaguquki eliqondisayo elinokuhlanganiswa okufanele, ukusetshenziswa okufanele kanye nokugcinwa okusebenzayo ngokuvamile kufanele kusetshenziswe iminyaka engu-2~3, futhi ipheya yamabheringi kufanele futhi isetshenziswe isikhathi esingaphezu kwesigamu sonyaka.
Kumele kuqashelwe ukuthi izinga lama-bearings athengwe emakethe likhathaza kakhulu.I-radial runout kanye ne-axial clearance yamasongo angaphakathi nangaphandle kanye nokumelana nokugqokwa kobuhlalu nama-ballistics akuthembeki ngokwanele.Nakuba ukupakishwa kwayo nezimpawu zayo kungabonakali, qaphela.Khetha ukusebenzisa ngokuqapha.
Unilateral usilika okuxekethile
Isivinini sesigubhu socingo asihambisani nokuzungeza okuya phambili nokuhlehlayo, okuhlobene eduze nendlela yokuphakela ucingo.Ngokwemiphumela yokuhlola, singabona ukuthi intambo ye-molybdenum ayikhululiwe ngokwezinga elithile futhi ngeke ithinte umphumela wokusika.Inkinga kasilika oxekethile iqedwe ngokuphelele, kodwa ijubane lesigubhu sikasilika alihambisani nokuzungeza okuya phambili nokuhlehlayo, kodwa akuqediwe ngokuphelele.
Ngamafuphi, esikhathini esizayo: uma isimo esingenhla senzeka ethuluzini lomshini othile, kufanele siqale sihlole ukuthi isifutho samanzi singakwazi yini ukumboza ngokuphelele ucingo lwe-molybdenum, ukuze isipholile singene ngokugcwele igebe lokusika ukuze senze ukukhishwa okuphumelelayo kanye ne-arc. inqubo yokucisha, futhi uhlole izintambo ezingenhla nezingezansi.Ukuqina kwefreyimu, ikakhulukazi ukuthi izikulufi zilungiswe ngokuphumelelayo, ngaphezu kwalokho, kuyadingeka ukunaka ukuthi indawo yokuxhumana yefreyimu yocingo kanye ne-scraping surface yekholomu ngemva kokuba ipuleti yokucindezela ifreyimu yocingo ixhumene ngempumelelo.Uma ingekho imbobo yesondo eliqondisayo, ukuthambekela kuzokwanda.
ukumelana
Ukuzungezisa kwesondo lomhlahlandlela kumele kuguquguquke.Ubude be-conductive block buphakeme kancane kunebha yebhasi yesondo lomhlahlandlela.Lapho ufaka ucingo lwe-molybdenum, amandla ocingo lwe-molybdenum kufanele abanjwe.Ukuthintana okuncane nokusebenza kahle nesondo lomhlahlandlela kanye ne-conductive block kufanelekile.Linganisa ukuphuma okuyisiyingi kwe-bobbin<0.02mm, bese ukhomba ukuthi ingabe i-bobbin iyashintshashintsha yini uma ihamba ngomugqa oqondile
Indlela: Nqamula induku yesikulufu bese uphusha isigubhu socingo.Sebenzisa igeji yokudayela ukukala ibha yebhasi eseceleni kanye nebha engaphezulu yebhasi yesigubhu.Kunomthelela omkhulu kumphumela wokusika.Uma isikulufu sokuhola sifakwe ngendlela engafanele, sizobangela ukumelana okungahambisani phakathi nokusebenza, okuholela ekugudlukeni okusobala kocingo lwe-molybdenum.
Indlela yokuthuthukisa isiphetho kwinqubo yokusika ucingo, ukuphela kokusika ucingo kuhlanganiswe izakhi ezimbili, eyodwa ubukhulu bomgodi okhishwe ngokukhishwa okukodwa, futhi i-RZ yayo ngokuvamile iphakathi kuka-0.05μ ~ 1.5μ, okuyiNcane. .
Eyesibili imithende ye-convex ne-concave ebangelwa ukuhamba.I-RZ yayo ivame ukuba phakathi kuka-1μ ~ 50μ, futhi kungenzeka ukuthi ibe mkhulu njengo-0.1MM noma ngaphezulu, okuyisici esibaluleke kakhulu sokuqeda ukusika ucingo.Ngesikhathi esifanayo, ihambisana nemigqa emnyama nemhlophe yokuhlehla, enikeza abantu umthelela wokubuka onamandla kakhulu.
Ukulawula usayizi womgodi ngenxa yokuphuma okukodwa kulula, ngokumane unciphise amandla okushaya kwenhliziyo okukodwa.Ukuthi nje amandla e-pulse eyodwa mancane kangangokuthi i-workpiece ewugqinsi ayikwazi ukunqunywa, noma ngisho nesimo esingenayo i-sparking esinomjikelezo omfushane kuphela futhi akukho kukhishwa.
Lokhu kufana ne-fine gauge ku-EDM, okuholela emishinini engazinzile esebenza kahle kakhulu kanye nokuphuma kabi kwama-chip.Ngaphezu kwalokho, i-RZ ebangelwa imigodi yokukhipha kanye ne-RZ ebangelwa imigqa yokushintsha ayikho ngokulandelana okufanayo kobukhulu, ngakho-ke kubaluleke kakhulu ukulawula i-RZ ehambisana nemigqa yokuthutha.
Ubuvila nokunemba kokuzala
Ukungaguquguquki kokungezwani lapho wehla futhi wehla nezinye izizathu kubangela ukunyakaza okungaguquki kwezintambo zezintambo eziya phezulu naphansi.Lesi sici somshini yisizathu esiyinhloko sokuguquguquka nokufiphala kohambo lokuya emsebenzini.
Ukuthatha izinyathelo ezilandelayo kuzothuthukisa isiphetho ngokwezinga elithile
1. Nciphisa ngokufanelekile ububanzi be-pulse kanye ne-peak current, okungukuthi, ukunciphisa ubukhulu bomgodi wokugqwala.
2. Igayidi ne-bearing igcina ukunemba okuhle nokusebenza kahle, inciphisa ukunyakaziswa kwentambo nokugxuma kwentambo, futhi igcine umzila wokunyakaza kwentambo ube mncane.
3. Ucingo lugcina ukushuba okufanelekile, futhi lulungisa isondo lomhlahlandlela kanye nebhulokhi yokudla, ukuze ukungezwani endaweni yokusebenza kuhlale kungashintshile lapho ucingo lwehla lukhuphuka.
4. Ucingo akufanele luqine kakhulu, futhi amanzi akufanele abe masha kakhulu.Amanzi amasha ngokuqinisekile anenzuzo ekusebenzeni kahle kokusika, kodwa ukuphela kokusika akuyona into engcono kakhulu.
5. Engeza i-splint emaceleni angaphezulu naphansi e-workpiece encane kakhulu, ukuze imivimbo ehlehlayo ifakwe ngaphakathi kwebanga le-splint.
6. Kubaluleke kakhulu futhi ukuthi ukunyakaza kwe-XY kuzinze futhi kunembile, kube nokwethembeka okuhle kokulandela kanye nokukhasa okungavimbeli.
7. Gcina ukulandelela kokuguqulwa kwemvamisa okuzinzile nokuxekethile.
8. Sika kabusha noma ukusikeka okuningi ngenani elifanele lokusika, shanela indawo yokusika kanye lapho inani lokusika lilincane, futhi ulungise usayizi ngokunembile.
Kokubili ukunemba kanye nesiphetho kuzoba nemiphumela enenzuzo.Ukushanela izikhathi ezintathu zilandelana kuzosusa imigqa ehlehlayo.Uma nje ithuluzi lomshini linokunemba okuphezulu kokubeka okuphindaphindiwe, futhi imvume efanelekile isetshenziselwa ukucubungula okuqhubekayo, ukuqedwa kwendawo yokusika kuzothuthukiswa iphuzu elilodwa noma amabili.Izinga, umphumela ufana nomshini wokusika izintambo ezihamba kancane, futhi akuthathi isikhathi esiningi, okungenye yezinzuzo zomshini wokusika ucingo olusheshayo.
9. Ezindaweni zokusebenza eziwugqinsi, izintambo ezimfishane zingasetshenziswa ngendlela efanele, futhi okuphakelayo okuhlehlisayo ngesikhathi esisodwa kungaphansi kwengxenye yobubanzi bocingo, okubuye kufihle imigqa ehlehlayo.Impela kuwukumboza nje
