Ama-bearings amancane - amapuleti omzimba amancane okusetshenziswa okukhulu
Ama-micro bearingsbheka uchungechunge lwe-metric, olunobubanzi bangaphandle obungaphansi kuka-9mm; uchungechunge lwasebukhosini, zonke izinhlobo zamabheringi anobubanzi bangaphandle obungaphansi kuka-9.525mm. Izinto eziyinhloko yinsimbi ethwalayo, insimbi engagqwali, ipulasitiki, i-ceramic, njll., lapho ububanzi bangaphakathi u-Z bungaba ngu-0.6mm, kanti ububanzi bangaphakathi obujwayelekile bungu-1mm.
Ama-micro ball bearingzenziwe ngensimbi yekhabhoni, insimbi ethwala, insimbi engagqwali, ipulasitiki, izinto zobumba nezinye izinto, ezinokusetshenziswa okubanzi, ezifanele ukujikeleza ngesivinini esikhulu, i-torque ephansi yokungqubuzana, ukudlidliza okuphansi, izidingo zomsindo ophansi (izinto zensimbi yekhabhoni azivamile ukusetshenziswa ngamakhasimende, kumakhasimende asezingeni eliphansi).
1. Izici zomkhiqizo
Ama-micro bearingszifanele zonke izinhlobo zemishini yezimboni, ama-motor amancane ajikelezayo, njll.; Eminyakeni yamuva nje, kube nokwanda kwesidingo sezinhlobo ezincane zala madivayisi, ezilula, nezinodonga oluncane.
Kuma-miniature bearings amancane kakhulu, kunezinhlobo ezingu-18 zama-micro bearings anobubanzi bangaphakathi obungu-φ2mm noma ngaphansi, kanye nezinhlobo ezingu-6 zochungechunge lwe-Imperial R.
2. Ukusetshenziswa okuyinhloko
Imishini yasehhovisi Ama-Micro motors, ama-soft drive Ama-pressure rotors, ama-dental drill Ama-hard disk motors, ama-stepper motors Ama-video recorders Ama-magnetic drums, amamodeli amathoyizi Ama-computer fans, ama-encoder kanye nezinye izinkambu.
3. Khetha izakhi ezingu-11 zama-micro bearings
Uma ukhetha ama-micro bearings, kunezinto eziningi okudingeka zicatshangelwe ukuze kugwenywe uhlobo lokukhetha kanye namanye amaphutha, bese manje ufingqa izinto eziyi-11 ezibalulekile zokukhetha ama-micro bearings ukuze ubhekisele kuzo.
1. Umthwalo we-radial othwala okuncane
Ama-bearings athwala kakhulu imithwalo ye-radial ama-bearings aphakathi nendawo. Nge-engeli yokuxhumana eqondile engu-A0≤45°, ama-roller bearings anobukhulu obufanayo angamelana nemithwalo ye-radial emikhulu kune-ball bearings.
Ama-roller bearings anombala we-N kanye ne-NU cylindrical angathwala imithwalo ye-radial kuphela, kanti ezinye izinhlobo zama-centripetal bearings zingathwala imithwalo ye-radial kanye ne-axial.
2. Umthwalo we-Axial wama-miniature bearings
Ibhereyi ethwala kakhulu imithwalo ye-axial ngokuvamile iyibhereyi yokusunduza, kanye ne-angle yayo yokuxhumana ejwayelekile engu-A0>45°. Amabhereyi okusunduza kanye namabhereyi ebhola lokusunduza angama-angular angamelana namandla e-axial ohlangothini olulodwa noma zombili ngasikhathi sinye, kuye ngesakhiwo. Uma amandla okuthwala ephezulu kakhulu, amabhereyi e-roller ayisilinda asunduza kanye namabhereyi e-roller ayisiyingi asunduza ayathandwa.
Ama-roller bearings ayindilinga e-Thrust kanye nama-angles e-thrust angular contact ball bearings angathwala imithwalo ye-axial kanye ne-radial, kanti amanye ama-thrust bearings angathwala imithwalo ye-axial kuphela.
3. Isinxephezelo sobude bebhereyini encane engenisiwe ngokwayo
Ukusekela umgodi kanye nebhereyitha kuvame ukusebenzisa inhlanganisela yebhereyitha eqondile kanye nebhereyitha yokuhamba. Amabhereyitha okuhambayo akhokhela amaphutha obude bomgodi kanye nokwanda kokushisa.
Ama-bearings e-NU kanye ne-N cylindrical roller angama-bearings ahambayo afanelekela ubude bawo ngokwawo. Amasongo angaphakathi nangaphandle e-bearings angafakwa kahle.
4. Isinxephezelo sobude bokulingana okushelelayo kwebhere elincane
Ama-miniature bearings angahlukaniswa, njenge-deep groove ball bearings kanye nama-spherical roller bearings, angasetshenziswa futhi njenge-traveling bearings. Elinye lama-ferrules amabili alolu hlobo lwe-bearings liyahlanganiswa futhi alinawo umphezulu wokulungisa we-axial. Ngakho-ke, elinye lama-ferrules e-bearings lingathuthwa phezu komphezulu walo we-bearings.
5. Okungahlukaniswaamabheringi amancane(ukunemba)
Lokhu kuyibhereyitha engafakwa ngokwehlukana nama-ferrule, futhi izinzuzo zayo ziyabonakala uma womabili ama-ferrule efakwe kahle.
Ama-bearings ahlukaniswayo afaka ama-bearings ebhola lokuxhumana anamaphuzu amane, ama-bearings ebhola lokuxhumana angular angular anezindandatho zangaphakathi ezimbili eziyingxenye, ama-bearings e-cylindrical roller, ama-bearings e-roller anciphile, ama-bearings e-thrust ball, ama-bearings e-thrust cylindrical roller, kanye nama-bearings e-thrust spherical roller.
Ama-bearings angahlukani afaka: ama-deep groove ball bearings, ama-single-row angular ball bearings, ama-spherical ball bearings, kanye nama-spherical roller bearings.
6. Ukuthwala okuncaneukunemba
Ezimweni eziningi, kwanele ukusebenzisa ama-rolling bearings anobukhulu obujwayelekile kanye nokunemba kokujikeleza.
Uma izidingo ziphakeme, ama-bearings adinga izilinganiso zokunemba okuphezulu.
7. Ama-micro bearingsungasinxephezeli ukungathathi hlangothi
Ukungalungi kahle kwenzeka lapho kucutshungulwa indawo yokuhlangana kwejenali noma indawo yokuhlangana kwezindlu, ikakhulukazi lapho indawo yokuhlangana ingaqedwanga endaweni eyodwa yokuhlanganisa. Ukungalungi kahle kungenzeka nalapho kusetshenziswa izindawo zokuhlangana (isibonelo, izindawo zokuhlangana ze-flange noma izindawo zokuhlangana eziqondile). Lapho ishaft igobile futhi iguquguquka ngenxa yomthwalo osebenzayo, okuholela ekuthambekeni kwezindandatho zangaphakathi nezangaphandle zebhereyi, kuzokwenzeka nokungalungi kahle.
Ama-bearing ayisiyingi angavala isikhala sokungalungi kahle nokuthambekela, njenge-spherical ball bearing, i-centripetal kanye ne-thrust spherical roller bearing. Lawa ma-bearing ane-concave spherical outer ring raceway lapho i-rolling element kanye ne-inner ring kungajikeleza khona. Amandla ala ma-bearing okuvala isikhala sokujika kwe-central shaft ancike ohlotsheni lwawo, usayizi, kanye nephrofayili yomthwalo.
Kokubili ama-bearings ayindilinga kanye nama-thrust ball bearings ane-races anendawo yokubeka eyindilinga: i-engeli yokuphambuka ekhokhelwayo ingalungiswa uma ifakwa emjahweni oyindilinga ogobile.
8. Isivinini sokuthwala esincane
Ukungqubuzana kwama-bearings omugqa owodwa kuphansi kakhulu, ngakho-ke kungenzeka ukufinyelela isivinini esiphezulu se-Z. Lawa ma-bearings atholakala kuma-ball bearings ajulile angamelana nemithwalo ye-radial kanye nama-angler contact ball bearings angamelana nemithwalo ehlanganisiwe.
Ukuze kuthuthukiswe ukunemba kobukhulu, ukunemba kokujikeleza kanye nengxenye yokuhlangana kwebhereyi, ukusetshenziswa kwezindlela zokugcoba nokupholisa, kanye nokusetshenziswa kwezinhlobo ezikhethekile zamakheji kungandisa isivinini sokujikeleza esivumelekile sebhereyiyi.
Ukusebenza komsindo ophansi
Umsindo ophansi wokusebenza uvame ukudingeka ezinjinini ezincane, emishinini yehhovisi kanye nasezintweni zasendlini.
9. Ukuthwala okuncaneimbobo ekhonjisiwe
Ama-bearings anezimbobo ezi-conical angafakwa ngqo kuma-journals athambile (isb. ama-bearings angama-single kanye nama-double row cylindrical roller ekwakhiweni okunembe kakhulu). Uma ufaka la ma-bearings, i-radial clearance ethile ingalungiswa.
Ama-bearings amaningi ebhola eliyindilinga, ama-bearings e-drum roller kanye nama-bearings e-spherical roller ane-conical bore angafakwa ku-jenali eyindilinga ene-sleeve eqinile. Lawa ma-bearings kulula kakhulu ukuwafaka nokuwasusa.
10. Ukuqina kokuthwala okuncane
Ukuqina kwama-bearings angenisiwe kuvame ukubhekisela emandleni adingekayo ukuze kukhiqizwe ukuguqulwa okuthile kwe-elastic kwe-bearings. Ama-bearings ku-spindle kanye ne-pinion shaft yomshini adinga izinga eliphezulu lokuqina. Ngenxa yezimo zokuxhumana ezahlukene phakathi kwe-rolling element kanye ne-raceway, ukuqina kwama-roller bearings kuphakeme kunokwama-ball bearings.
11. Ukungqubuzana kwe-micro bearing
Ngaphezu kokushiswa nokuhlakazeka, ukungqubuzana kwangaphakathi nakho kudlala indima ebalulekile ekunqumeni izinga lokushisa lokusebenza kwebhereyi. Amabhereyi okungqubuzana aphansi yilawa: amabhereyi ebhola ajulile anemithwalo ye-radial, amabhereyi ebhola lokuxhumana elingumugqa owodwa kanye namabhereyi e-cylindrical roller anezikheji. Amabhereyi avaliwe ngokuxhumana, amabhereyi e-cylindrical roller agcwele ngokugcwele, kanye namabhereyi e-thrust roller konke kudala ukungqubuzana okuphezulu.
