Uhlobo lokukhetha indlela yama-motor bearings

Ukukhetha uhlobo lwamabhere Amamodeli athwalayo ajwayelekile asetshenziswa ezinjini ama-deep groove ball bearings, ama-cylindrical roller bearings, ama-roller bearings, nama-angular contact ball bear.Ama-bearings emikhawulweni yomibili yama-motor amancane asebenzisa ama-deep groove ball bear, ama-motor anosayizi omaphakathi asebenzisa ama-roller bear ekugcineni komthwalo (ngokuvamile asetshenziselwa izimo zomthwalo omkhulu), kanye nama-ball bearings ekugcineni okungawumthwalo (kodwa kukhona namacala aphikisanayo). , njengama-motor angu-1050kW).Izinjini ezincane nazo zisebenzisa ama-angular contact ball bearings.Ama-roller bearings ayindilinga asetshenziswa kakhulu kumamotho amakhulu noma ama-motor mpo.Motor bearingsayidingi umsindo ongajwayelekile, ukudlidliza okuphansi, umsindo ophansi, kanye nokukhuphuka kwezinga lokushisa eliphansi.Ngokuhambisana nemithetho yokukhetha kuthebula elingezansi, lezi zici ezilandelayo zivame ukucatshangelwa ukuze kuhlaziywe indlela yokukhetha iphrojekthi.Isikhala sokufakwa kwe-bearing singafaka usayizi wokuthwala endaweni yokufaka yokuthwala.Ngenxa yokuthi ukuqina nokuqina kwe-shaft kugcizelelwa lapho kuklanywa uhlelo lwe-shaft, ububanzi be-shaft ngokuvamile bunqunywa kuqala.Kodwa-ke, kunochungechunge oluhlukahlukene losayizi kanye nezinhlobo zama-rolling bearings, lapho kufanele kukhethwe khona izilinganiso ezifanele kakhulu zokuthwala.

Umthwalo Usayizi, isiqondiso kanye nemvelo yomthwalo othwalayo [umthamo womthwalo wokuthwala uvezwa umthwalo olinganiselwe oyisisekelo, futhi inani lawo liboniswa etafuleni losayizi wokuthwala] Umthwalo wokuthwala ugcwele izinguquko, njengosayizi we umthwalo, kungakhathaliseki ukuthi kunomthwalo we-radial kuphela, nokuthi umthwalo we-axial uyindlela eyodwa noma indlela emibili, izinga lokudlidliza noma ukushaqeka, njalonjalo.Ngemva kokucabangela lezi zici, khetha uhlobo olufanele kakhulu lwesakhiwo sokuthwala.Ngokuvamile, umthwalo we-radial wamabheringi e-NSK anobubanzi obufanayo bangaphakathi uyahlukahluka ngokuya ngochungechunge, futhi umthwalo olinganiselwe ungabhekwa ngokuya ngesampula.Uhlobo oluthwalayo ijubane lalo lingakwazi ukuzivumelanisa nesivinini somshini [inani elilinganiselwe lejubane elithwalayo livezwa isivinini esiwumkhawulo, futhi inani lalo liboniswa kuthebula losayizi wokuthwala] Ijubane lomkhawulo lokuthwala alincikile kuphela ohlotsheni oluthwalayo. , kodwa futhi kukhawulelwe kusayizi wokuthwala, uhlobo lwekheji, kanye nezinga lokunemba , izimo zomthwalo nezindlela zokugcoba, njll., Ngakho-ke, lezi zici kufanele zicatshangelwe lapho kukhethwa.Amabhereli esakhiwo esifanayo anobubanzi obungaphakathi obungu-50 ~ 100mm anesivinini esiphezulu somkhawulo;ukunemba kokuzungezisa kunokunemba kokuzungezisa okudingekile kohlobo lwebheringi [ukunemba kosayizi nokunemba kokuzungezisa kwebheriyo kufanekiswe yi-GB ngokohlobo lokuthwala].

Ukunemba kokuthwala kunqunywa ngokuhambisana nesilinganiso sejubane kuya kwijubane lomkhawulo.Uma kuphakeme ukunemba, isivinini somkhawulo siphezulu futhi siba sincane isizukulwane sokushisa.Uma idlula u-70% wesivinini esilinganiselwe sokuthwala, izinga lokunemba lokuthwala kufanele lithuthukiswe.Ngaphansi kwemvume efanayo ye-radial yasekuqaleni, isizukulwane sokushisa sincane, ukuthambekela okuhlobene kweringi yangaphakathi neringi yangaphandle.Ukuhlaziywa kwezinto ezibangela ukuthambekela okuhlobene kweringi yangaphakathi kanye neringi yangaphandle yebheringi (njengokuchezuka kwe-shaft okubangelwa umthwalo, ukunganembi kahle kwe-shaft kanye nezindlu) Noma iphutha lokufaka), bese ukhetha uhlobo lokuthwala. ezingavumelana nalesi simo sesevisi.Uma ukuthambekela okuhlobene phakathi kweringi yangaphakathi nendandatho yangaphandle kukukhulu kakhulu, ukuthwala kuzolimala ngenxa yomthwalo wangaphakathi.Ngakho-ke, i-self-aligning roller bearing engakwazi ukumelana nalokhu kuthambekela kufanele kukhethwe.Uma ukuthambekela kukuncane, ezinye izinhlobo zama-bearings zingakhethwa.Indlela yokukhetha into yokuhlaziya I-bearing configuration shaft isekelwa ama-bearings amabili eziqondisweni ze-radial kanye ne-axial, futhi uhlangothi olulodwa luwuhlangothi olungaguquki, oluthwala kokubili imithwalo ye-radial ne-axial., edlala indima ekunyakazeni kwe-axial okuhlobene phakathi kwe-shaft engaguquki kanye nezindlu ezithwala.Olunye uhlangothi luwuhlangothi lwamahhala, oluthwala umthwalo we-radial kuphela futhi lungahamba ngokulinganayo endaweni ye-axial, ukuze kuxazululwe inkinga yokunwetshwa nokufinyela kwe-shaft okubangelwa ukushintsha kwezinga lokushisa kanye nephutha lezikhala lama-bearings afakiwe.Kuma-shafts amafushane, uhlangothi olulungisiwe alukwazi ukuhlukaniswa nohlangothi lwamahhala.

I-fixed-end bear ikhethelwa ukuma kwe-axial nokulungiswa kwe-axial ukuthwala umthwalo we-axial we-bidirectional.Ngesikhathi sokufakwa, amandla ahambisanayo adinga ukucatshangelwa ngokuvumelana nobukhulu bomthwalo we-axial.Ngokuvamile, ama-ball bearings akhethwa njenge-fixed end kanye nama-free-end bearings akhethiwe ukuze agweme.Ukunwetshwa nokufinyezwa kwe-shaft okubangelwa ukushintsha kwezinga lokushisa ngesikhathi sokusebenza, kanye nesimo se-axial esisetshenziselwa ukulungisa ukuthwala kufanele sithwale imithwalo ye-radial kuphela, futhi indandatho yangaphandle kanye negobolondo ngokuvamile kwamukela ukulingana kwe-clearance, ukuze i-shaft ibe yi-axially. kugwenywe kanye ne-bearing lapho i-shaft ikhula., Ngezinye izikhathi ukugwema i-axial kwenziwa ngokusebenzisa indawo ehambisanayo ye-shaft kanye nendandatho yangaphakathi.Ngokuvamile, i-cylindrical roller beararing ikhethwa njengesiphetho samahhala kungakhathaliseki ukuthi isiphetho esinqunyiwe nesiphetho samahhala.Lapho ukuthwala kukhethiwe, lapho ibanga phakathi kwama-bearings lincane futhi ithonya lokwandiswa kwe-shaft lincane, sebenzisa amantongomane noma ama-washers ukuze ulungise imvume ye-axial ngemva kokufakwa.Ngokuvamile, ezimbili zikhethiwe.Ama-deep groove ball bearings noma ama-roller bearings amabili ayindilinga angasetshenziswa njengosekelo lwesiphetho esinqunyiwe nesiphetho samahhala noma lapho kungekho mehluko phakathi kwesiphetho esinqunyiwe nesiphetho samahhala.Imvamisa yokukhweza nokwehliswa kanye nendlela yokukhweza nokwehliswa, njengokuhlola okuvamile, amathuluzi okukhweza nawokwehlisa ayadingeka ekukhwezeni nasekwehleni.Isivinini nomthwalo yizici ezimbili ezibalulekile.Ngokuqhathanisa phakathi kwejubane nokujikeleza komkhawulo, kanye nokuqhathanisa phakathi komthwalo owamukelwe kanye nomthwalo olinganiselwe, okungukuthi, ukuphila kokukhathala okulinganiselwe, ifomu lesakhiwo sokuthwala linqunywa.Lezi zici ezimbili zigqanyiswe ngezansi.
