Okokuqala, isakhiwo esiyisisekelo sokuthwala
Ukwakheka okuyisisekelo kokuthwala: indandatho yangaphakathi, indandatho yangaphandle, umzimba ogoqayo, ikheji
Iringi yangaphakathi: ngokuvamile ifanelana eduze ne-shaft, futhi izungezisa ndawonye.
Iringi yangaphandle: imvamisa iba noguquko lwesihlalo esithwele, ikakhulukazi ukusekela umphumela.
Indandatho yangaphakathi nengaphandle inensimbi engu-GCr15, futhi ubulukhuni ngemva kokwelashwa kokushisa yi-HRC60~64.
Isici esigoqayo: ngekheji elihlelwe ngokulinganayo endandatho yangaphakathi kanye nomsele wendandatho yangaphandle, ukwakheka kwawo, usayizi, inombolo kuthinta ngqo umthamo wokuthwala umthwalo kanye nokusebenza.
Ikheji: Ngaphezu kokuhlukanisa ngokulinganayo into eginqikayo, iphinda iqondise ukuzungezisa kwento eginqikayo futhi ithuthukise ngempumelelo ukusebenza kokugcotshwa kwangaphakathi kwebheringi.
Ibhola lensimbi: Izinto ezisetshenziswayo ngokuvamile zinensimbi engu-GCr15, futhi ubulukhuni ngemva kokwelashwa kokushisa yi-HRC61~66.Ibanga lokunemba lihlukaniswe laba ngu-G (3, 5, 10, 16, 20, 24, 28, 40, 60, 100, 200) ukusuka phezulu kuye kokuphansi kuye ngokubekezelelana kwe-dimensional, ukubekezelelana komumo, inani legeji kanye nobulukhuni bomhlaba.
Kukhona nesakhiwo sokuthwala esisizayo
Isembozo sothuli (sealing ring) : ukuvimbela into yangaphandle ukuthi ingangeni ku-bearing.
Gcoba: gcoba, nciphisa ukudlidliza nomsindo, donsa ukushisa kwe-friction, ukwandisa isikhathi sokusebenza.
Okwesibili, ukuhlukaniswa kwama-bearings
Ngokwezakhiwo zokungqubuzana zezingxenye ezihambayo zihlukile, ama-bearings angahlukaniswa abe ama-rolling bearings kanye nama-rolling bearings izigaba ezimbili.Kuma-bearings aginqikayo, avame kakhulu ama-deep groove ball bearings, ama-cylindrical roller bearings nama-thrust ball bearings.
Amabhola e-deep groove ball ikakhulukazi athwala imithwalo ye-radial, futhi angathwala imithwalo ye-radial kanye nemithwalo ye-axial ndawonye.Uma kusetshenziswa umthwalo we-radial kuphela, i-Engeli yokuxhumana inguziro.Uma i-deep groove ball bearing inokususwa kweradial okukhulu kakhulu, inokusebenza kokuthwala okuthintana kwe-angular futhi ingamelana nomthwalo we-axial omkhulu kakhulu, i-coefficient ye-friction ye-deep groove ball bearing incane, kanye nesivinini sokuzungezisa umkhawulo siphezulu.
Ama-deep groove ball bearings angama-bearings angokomfanekiso kakhulu anokusetshenziswa okubanzi.Ilungele ukuzungezisa ngesivinini esikhulu kanye nokusebenza ngokuzungezisa ngesivinini esikhulu, futhi ihlala isikhathi eside futhi ayidingi ukulungiswa njalo.Lolu hlobo lokuthwala lune-coefficient encane yokungqubuzana, isivinini somkhawulo ophezulu, isakhiwo esilula, izindleko eziphansi zokukhiqiza kanye nokufinyelela kalula ukunemba okuphezulu kokukhiqiza.Ibanga losayizi nokushintsha kwesimo, okusetshenziswe kumathuluzi anembayo, izinjini ezinomsindo ophansi, izimoto, izithuthuthu futhi ngokuvamile imishini nezinye izimboni, kuwuhlobo oluvame kakhulu lwamabheringi obunjiniyela bemishini.Ikakhulukazi ithwala umthwalo we-radial, ingathwala inani elithile lomthwalo we-axial.
I-Cylindrical roller bearing, umzimba ogoqayo uyi-centripetal rolling bearing ye-cylindrical roller bear.I-Cylindrical roller bearing kanye ne-raceway kukhona amabheringi okuthintana aqondile.Umthamo omkhulu wokulayisha, ikakhulukazi ukuthwala umthwalo we-radial.Ukungqubuzana phakathi kwesici esigoqayo kanye nonqenqema lwendandatho kuncane, okulungele ukusebenza ngesivinini esikhulu.Ngokuya ngokuthi indandatho ine-flange, ingahlukaniswa ngo-NU\NJ\NUP\N\NF namanye amabheringi anomugqa owodwa, kanye ne-NNU\NN namanye ama-bearings anemigqa emibili.
I-roller eyi-cylindrical enendandatho yangaphakathi noma yangaphandle ngaphandle kwembambo, izindandatho zayo zangaphakathi nangaphandle zikwazi ukuhambisa ngokuhlobene ne-axially ngakho-ke ingasetshenziswa njenge-bearing-end bear.Olunye uhlangothi lwendandatho yangaphakathi kanye nendandatho yangaphandle inombambo ophindwe kabili, kanti olunye uhlangothi lwendandatho ine-cylindrical roller ephethe imbambo eyodwa, engakwazi ukumelana nomthwalo we-axial ohlangothini olufanayo ngezinga elithile.Amakheji eshidi lensimbi avame ukusetshenziswa, noma amakheji aqinile enziwe nge-alloy yethusi.Kodwa abanye babo basebenzisa amakheji okwenza i-polyamide.
Ama-thrust ball bearings aklanyelwe ukumelana nemithwalo ye-thrust ngesikhathi sokusebenza ngesivinini esikhulu futhi akhiwe ngamasongo e-gasket ane-raceway groove yokugingqika kwebhola.Ngenxa yokuthi iringi iwumumo wephedi lesihlalo, i-thrust ball bear ihlukaniswe yaba izinhlobo ezimbili: uhlobo lwephedi yesisekelo esiyisicaba kanye nokuqondanisa uhlobo lwesihlalo esiyindilinga.Ngaphezu kwalokho, ama-bearings anjalo angakwazi ukumelana nemithwalo ye-axial, kodwa hhayi imithwalo ye-radial.
I-thrust ball bearing iqukethe iringi yesihlalo, iringi ye-shaft kanye nokuhlanganiswa kwekheji yebhola lensimbi.Indandatho ye-shaft ihambisana ne-shaft, futhi indandatho yesihlalo ihambisana negobolondo.Ama-thrust ball bearings afaneleka kuphela ukuthwala ingxenye yomthwalo we-axial, izingxenye zejubane eliphansi, njengamahhuku e-crane, amaphampu amile, ama-centrifuge aqondile, ojeke, amaretareda aphansi, njll. Iringi ye-shaft, iringi yesihlalo kanye nomzimba ogoqayo ziyahlukaniswa futhi zingafakwa futhi zihlakazwe ngokwehlukana.
Okwesithathu, ukuphila okuzalayo okugingqikayo
(1) Izinhlobo eziyinhloko zokulimala kwama-bearings
Ukukhathala:
Kuma-bearings aginqikayo, ukuthwala umthwalo kanye nokunyakaza okuhlobene kwendawo yokuxhumana (umzila womjaho noma indawo yomzimba egoqayo), ngenxa yomthwalo oqhubekayo, owokuqala ngaphansi kobuso, ukujula okuhambisanayo, ingxenye ebuthakathaka yokuqhekeka, bese ithuthukela ekujuleni. indawo yokuxhumana, ukuze ungqimba olungaphezulu lwe-metal flake luphume, okuholela ekuthwaleni abakwazi ukusebenza ngokujwayelekile, le nto ibizwa ngokuthi i-spalling yokukhathala.I-spalling yokugcina yokukhathala kwama-rolling bearings kunzima ukuyigwema, empeleni, esimweni sokufakwa okujwayelekile, ukugcotshwa nokubeka uphawu, iningi lomonakalo othwala umonakalo wokukhathala.Ngakho-ke, impilo yesevisi yama-bearings ngokuvamile ibizwa ngokuthi impilo yesevisi yokukhathala yama-bearings.
I-deformation yepulasitiki (i-deformation unomphela):
Lapho i-rolling bear ingaphansi komthwalo oweqile, ukuguqulwa kwepulasitiki kubangelwa emzimbeni ogoqayo kanye nokugoqa kothintana naye, futhi ukugoqa phezulu kukhiqiza isibotho, okuholela ekudlidlizeni okukhulu nomsindo ngesikhathi sokusebenza kwe-bearing.Ngaphezu kwalokho, izinhlayiya zangaphandle zangaphandle ku-bearing, umthwalo omthelela owedlulele, noma lapho ukuthwala kumile, ngenxa yokudlidliza komshini nezinye izici zingase zikhiqize ukuhlehla endaweni yokuxhumana.
Ukugqoka nokuklebhuka:
Ngenxa yokunyakaza okuhlobene kwezinto eziginqikayo kanye nomzila womjaho kanye nokuhlasela kokungcola nothuli, into eginqikayo nokugingqika phezulu kubangela ukuguga.Lapho inani lokugqoka likhulu, imvume yokuthwala, umsindo nokudlidliza kwanda, futhi ukunemba kokusebenza kwe-bearing kuyancipha, ngakho-ke kuthinta ngokuqondile ukunemba kwezinye izinjini eziyinhloko.
Okwesine, izinga lokunemba lokunemba kanye nendlela yokumela ukususa umsindo
Ukunemba kwama-bearings aginqikayo kuhlukaniswe ngokunemba kwe-dimensional kanye nokunemba okujikelezayo.Izinga lokunemba selimisiwe futhi lihlukaniswe ngamaleveli amahlanu: P0, P6, P5, P4 kanye ne-P2.Ukunemba kuye kwathuthukiswa kusuka ezingeni 0, uma kuqhathaniswa nokusetshenziswa okujwayelekile kwezinga 0 kwanele, ngokuya ngezimo noma izikhathi ezahlukene, izinga lokunemba elidingekayo alifani.
Emihlanu, evame ukubuzwa imibuzo ehambisanayo
(1) Ukuthwala insimbi
Izinhlobo ezivame ukusetshenziswa zensimbi eginqikayo: insimbi enekhabhoni ephezulu, insimbi ene-carburized, insimbi engagqwali, izinga lokushisa eliphezulu elinensimbi
(2) Ukugcoba ama-bearings ngemva kokufakwa
Ukugcoba kuhlukaniswe ngezinhlobo ezintathu: amafutha, amafutha okugcoba, ukugcoba okuqinile
Ukugcotshwa kungenza i-bearing ihambe ngokujwayelekile, igweme ukuthintana phakathi komzila womjaho nendawo eginqikayo, inciphise ukungqubuzana nokuguga ngaphakathi kwe-bearing, futhi ithuthukise isikhathi sesevisi yokuthwala.Igrisi inokunamathela okuhle nokumelana nokugqoka kanye nokumelana nezinga lokushisa, okungathuthukisa ukumelana ne-oxidation kwama-bearings okushisa aphezulu futhi kuthuthukise impilo yesevisi yama-bearings.I-grease ekuthwaleni akufanele ibe maningi, futhi amafutha amaningi azobe ephikisana.Lapho ijubane lokuthwala liphakeme, ingozi inkulu.Izokwenza kube khona ukusebenza lapho ukushisa kukhulu, kuzoba lula ukonakala ngenxa yokushisa okukhulu.Ngakho-ke, kubaluleke kakhulu ukugcwalisa amafutha ngokwesayensi.
Okwesithupha, okuhambisana nezinyathelo zokuphepha zokufaka
Ngaphambi kokufakwa, qaphela ukuthi kunenkinga ngekhwalithi ye-bearing, khetha kahle ithuluzi lokufaka elihambisanayo, futhi unake ukuhlanzeka kwe-bearing lapho ufaka i-bearing.Naka ukuphoqa ngisho nalapho uthepha, uthepha kancane.Hlola ukuthi ama-bearings afakwe kahle yini ngemva kokufakwa.Khumbula, ngaphambi kokuba umsebenzi wokulungiselela uphothulwe, ungathukululi i-bearing ukuze uvimbele ukungcola.
