Izici ze-, iyini i-thin section bearing?

Amabheringi esigaba esincaneinesigaba sokuthwala esincane kakhulu, esivumela ukwenziwa kube lula kanye nemikhiqizo elula, futhi sandisa ububanzi bezicelo. Ngokwezindlela zabo ezahlukene zokuvala, amabheringi esigaba esincane ngokuvamile ahlukaniswe kanje: uphawu lwerabha-RS, uphawu lwensimbi-ZZ, indawo eyisicaba, ikhadi lensimbi-K, ikhadi lethusi-M, njll.

 

Ukuze uthole i-torque ephansi yokungqubuzana, ukuqina okuphezulu kanye nokunemba okuhle kokujikeleza kweamabheringi anodonga oluncane, ama-bearing anezindonga ezincane asebenzisa amabhola ensimbi anobubanzi obuncane bangaphandle, kanti ukusetshenziswa kwemigodi engenalutho kuqinisekisa isikhala esilula nesokuxhuma. Ukuze i-bearing idlale umsebenzi wayo ngokujwayelekile, maqondana nokuthambisa, ama-bearing anezigaba ezincane ngokuvamile asebenzisa ukuthambisa ngamafutha kanye nokuthambisa ngamafutha, inhloso ukunciphisa ukungqubuzana kwangaphakathi kanye nokuguguleka kwe-bearing, ukuvimbela i-bearing ekushiseni ngokweqile, kanye nokuvimbela izinto zangaphandle ukuthi zingangeni ku-bearing ngaphakathi, noma ukuvimbela ukugqwala nokugqwala, ukuze kwandiswe impilo yesevisi ye-bearing. Ngesikhathi sokusetshenziswa, indawo yokuxhumana egoqekayo igcotshwa kahle, okuzokwandisa impilo; Ngokuphambene nalokho, uma i-viscosity kawoyela iphansi futhi ubukhulu befilimu kawoyela egcobayo bungebuhle, impilo izofinyezwa.

 

Ukunemba okudingekayoamabheringi ebhola anodonga oluncaneiphakeme kakhulu, ngoba udonga lwayo luncane kakhulu, ngakho-ke isisindo esingasithwala naso siphansi kakhulu, futhi ukumelana nomthelela kubi kakhulu, ngakho-ke lokhu kufanele kukhethwe ngokuya ngendawo yokusetshenziswa!

 

Amabhereyi ebhola anodonga oluncaneinesakhiwo esilula futhi kulula ukuyisebenzisa. Isetshenziswa kakhulu ukuthwala imithwalo ye-radial, kodwa lapho i-radial clearance ye-bearing ikhuliswa, inokusebenza okuthile kwama-angular contact ball bearing, futhi ingamelana nemithwalo ye-radial ne-axial ehlanganisiwe. Uma ijubane lokujikeleza liphezulu futhi kungafaneleki ukusebenzisa ama-thrust ball bearing, ingasetshenziswa futhi ukuthwala imithwalo ye-axial emsulwa. Uma kuqhathaniswa nezinye izinhlobo zama-bearing anobukhulu obufanayo, lolu hlobo lwe-bearing lune-friction coefficient encane kanye nomkhawulo wejubane eliphezulu. Kodwa-ke, alumelani nokushaywa futhi alufanelekeli ukuthwala imithwalo esindayo. I-equal section thin section bearing uhlobo lwe-bearing enobubanzi obukhethekile be-cross-section kanye nobukhulu; Usayizi ofanayo we-cross-sectional ungalingana nobubanzi obuningi obuhlukene be-bearing inner; Uma kuqhathaniswa nama-bearing ajwayelekile, ububanzi kanye nobukhulu buyanda ngokulingana nokwanda kobubanzi obungaphakathi be-bearing, kuyilapho ama-equal-section thin-section bearing andisa ububanzi obungaphakathi futhi agcine usayizi we-cross-sectional ungashintshi.

 

Ukuhlanganiswa kosayizi bezingxenye eziyisishiyagalolunye (kusukela ku-3/16" kuya ku-1") kanye nosayizi we-bore (kusukela ku-1" kuya ku-40") wobubanzi bokuthwala izingxenye ezincane kuzoholela kuma-bearings amaningi "ancane" ajwayelekile anezingxenye ezincane nama-bore amakhulu. Izinto zokuthwala izingxenye ezincane insimbi ye-chrome engu-52100 kanye nensimbi engagqwali engu-440C nazo zingafakwa i-chrome encane. Amamodeli amaningi angafakelwa izivalo noma izembozo zothuli. Kunezinhlobo ezintathu ezahlukene zama-bearings ezingxenye ezincane: ama-bearings ebhola ajulile, ama-bearings ebhola lokuxhumana angular, kanye nama-bearings ebhola lokuxhumana anamaphuzu amane. Uma kuqhathaniswa nama-bearings ajwayelekile, ama-bearings ezingxenye ezincane angenza ngcono ukwakheka kwesistimu kahle kakhulu futhi anciphise izindleko eziphelele. Lezi zinhlobo ezintathu zokwakha, ezihlanganiswe nama-roller ahlukene kanye nezinhlobo ezahlukene zekheji, zivumela ukudalwa kwemikhiqizo eminingi yokuthwala izingxenye ezincane ngokusekelwe kosayizi abalinganiselwe be-cross-section. Njengoba usayizi we-cross-sectional wama-shafts anezindonga ezincane ungashintshi ngobubanzi bangaphakathi, izidingo zesikhala sokufaka zihlala zifana, isisindo kuphela sishintsha kancane ngokushintsha kobubanzi bangaphakathi.

 

Ikakhulukazi kumadivayisi ezokwelapha, imishini yokukhanya, imishini yokuskena ye-infrared, amarobhothi, nakweminye imikhakha, isikhala sokufaka kanye nesisindo yizinto okufanele zicatshangelwe maqondana nezindleko zokuklama nezokukhiqiza. Ezimweni eziningi, noma ngabe intengo yemakethe yama-thin-section bearings iphakeme kune-bearings ejwayelekile enobukhulu obufanayo be-bore, ama-thin-section bearings anganciphisa isikhala sokufaka kanye nesisindo, okungaholela ekongeni izindleko okukhulu ekwakhiweni nasekusetshenzisweni kwesistimu.
