Okokuqala, isakhiwo esisisiseko sokuthwala
Ukubunjwa okusisiseko kokuthwala: i-ring yangaphakathi, i-ring yangaphandle, i-rolling body, i-cage
Iringi yangaphakathi: ihlala ihambelana ngokusondeleyo ne-shaft, kwaye ijikeleze kunye.
Umsesane wangaphandle: rhoqo kunye nenguqu yesihlalo esithwele, ikakhulu ukuxhasa umphumo.
Isixhobo sangaphakathi nangaphandle sithwele i-GCr15 yentsimbi, kwaye ukuqina emva konyango lobushushu yi-HRC60 ~ 64.
Into eqengqelekayo: ngokusebenzisa ikheji elungelelaniswe ngokulinganayo kwindandatho yangaphakathi kunye nomsele wangaphandle, imilo yayo, ubungakanani, inani lichaphazela ngokuthe ngqo umthamo wokuthwala umthwalo kunye nokusebenza.
I-Cage: Ukongeza ngokulinganayo ukwahlula i-element rolling, iphinda iqondise ukujikeleza kwento ejikelezayo kwaye iphucule ngokufanelekileyo ukusebenza kwangaphakathi kwe-lubrication yokuthwala.
Ibhola yentsimbi: Izinto eziphathekayo ngokubanzi zithwala i-GCr15 yentsimbi, kwaye ukuqina emva konyango lobushushu yi-HRC61 ~ 66.Ibakala lokuchaneka lahlulwe laba yi-G (3, 5, 10, 16, 20, 24, 28, 40, 60, 100, 200) ukusuka phezulu ukuya ezantsi ngokonyamezelo lwedimensional, ukunyamezela imilo, ixabiso legeyiji kunye noburhabaxa bomphezulu.
Kukwakho nesakhiwo esincedisayo sokuthwala
Isigqubuthelo sothuli (umsesane wokutywina) : Ukuthintela into yangaphandle ukuba ingangeni kwibheringi.
Gcoba: Gcoba, nciphisa ukungcangcazela kunye nengxolo, ukufunxa ubushushu be-friction, ukwandisa ixesha lenkonzo yokuthwala.
Okwesibini, ukuhlelwa kweebheringi
Ngokweempawu zokukhuhlana zamacandelo ahambayo ahlukeneyo, iibheringi zinokwahlulwa zibe yi-rolling bearings kunye nee-rolling bearings ezimbini.Kwiibheringi eziqengqelekayo, ezona zixhaphake kakhulu ziibhola ze-groove ezinzulu, ii-cylindrical roller bearings kunye nee-thrust ball bearings.
Iibhodi zebhola zegroove ezinzulu ikakhulu zithwala imithwalo yeradial, kwaye zinokuthwala imithwalo yeradial kunye ne-axial kunye.Xa kuphela umthwalo we-radial usetyenziswa, i-engile yoqhagamshelwano ngu-zero.Xa i-deep groove ibhola ithwele i-radial clearance enkulu kakhulu, inokusebenza koqhagamshelwano lwe-angular kwaye inokumelana nomthwalo omkhulu we-axial, i-coefficient ye-friction ye-deep groove ball bearing incinci, kunye nesantya somda wokujikeleza siphezulu.
Iibheringi zebhola zegroove ezinzulu zezona zinomfuziselo eziqengqelekayo ezinoluhlu olubanzi losetyenziso.Ilungele ukujikeleza kwesantya esiphezulu kunye nokusebenza okujikelezayo kakhulu, kwaye yomelele kwaye ayifuni ukulungiswa rhoqo.Olu hlobo lokuthwala lune-coefficient encinci ye-friction, isantya esiphezulu somda, isakhiwo esilula, iindleko eziphantsi zokuvelisa kunye nokulula ukufezekisa ukuchaneka okuphezulu kokuvelisa.Uluhlu lobungakanani kunye nokutshintsha imeko, esetyenziswa kwizixhobo ezichanekileyo, iimoto eziphantsi kwengxolo, iimoto, izithuthuthu kwaye ngokuqhelekileyo oomatshini kunye namanye amashishini, lolona hlobo luqhelekileyo lweebheringi zobunjineli bomatshini.Ikakhulu ithwele umthwalo weradial, inokuthwala umthamo othile we-axial load.
I-Cylindrical roller bearing, i-rolling body yi-centripetal rolling beararing ye-cylindrical roller bear.Ukuthwala i-Cylindrical roller kunye ne-raceway ziibheringi zoqhagamshelwano.Umthamo omkhulu womthwalo, ngakumbi ukuthwala umthwalo weradial.Ukungqubuzana phakathi kwento eqengqelekayo kunye nomphetho wendandatho incinci, ifanelekile ekusebenzeni ngesantya esiphezulu.Ngokuhambelana nokuba iringi ine-flange, ingohlulwa ibe yi-NU\NJ\NUP\N\NF kunye nezinye iibheringi zomqolo omnye, kunye ne-NNU\NN kunye nezinye iibheringi ezizikrozo ezimbini.
I-cylindrical roller ephethe indandatho yangaphakathi okanye yangaphandle ngaphandle kwembambo, iindandatho zayo zangaphakathi nangaphandle ziyakwazi ukuhamba ngokumalunga kunye ne-axially kwaye ngoko ke zingasetyenziswa njenge-free-end bear.Elinye icala lendandatho yangaphakathi kunye nendandatho yangaphandle inembambo ephindwe kabini, kwaye elinye icala lendandatho line-cylindrical roller ephethe intambo enye, enokumelana nomthwalo we-axial kwicala elifanayo ukuya kwinqanaba elithile.Iikheji zentsimbi zidla ngokusetyenziswa, okanye iikheji eziqinileyo ezenziwe nge-alloy yobhedu.Kodwa ezinye zazo zisebenzisa i-polyamide eyenza iikheji.
Iibearings zebhola ezithrust ziyilelwe ukuba zimelane nemithwalo etyhalayo ngexesha lokusebenza ngesantya esiphezulu kwaye zenziwe ngamakhonkco egasket anendawo yomdyarho wokuqengqeleka kwebhola.Ngenxa yokuba i-ringi iyimilo yesihlalo sephedi, i-thrust ball bearing yahlulahlulwe yazintlobo ezimbini: uhlobo lwesiseko esisicaba kunye nohlobo lwesitulo esingqukuva sokulungelelanisa.Ukongezelela, iibheringi ezinjalo ziyakwazi ukumelana nemithwalo ye-axial, kodwa kungekhona imithwalo ye-radial.
Ibearingi yebhola etyhutyhayo ineringi yokuhlala, iringi yeshaft kunye nendibano yekheji yentsimbi.Iringi ye-shaft ihambelana ne-shaft, kunye neringi yesihlalo ihambelana neqokobhe.Iibheringi zebhola ze-Thrust zifanelekile kuphela ukuthwala inxalenye yomthwalo we-axial, iinxalenye zesantya esisezantsi, ezifana ne-crane hook, iimpompo ezithe nkqo, ii-centrifuges ezithe nkqo, iijekhi, iiretareda ezisezantsi, njl njl. zahluliwe kwaye zinokufakelwa kwaye ziqhawuke ngokwahlukeneyo.
Okwesithathu, ukuqengqeleka kokuzala ubomi
(1) Iintlobo zomonakalo ophambili weebheringi eziqengqelekayo
Ukudinwa kuphele:
Kwiibherethi eziqengqelekayo, ukuthwala umthwalo kunye nentshukumo ehambelanayo yendawo yokunxibelelana (ugqatso okanye umphezulu womzimba oqengqelekayo), ngenxa yomthwalo oqhubekayo, owokuqala phantsi komphezulu, ubunzulu obuhambelanayo, inxalenye ebuthathaka yokuqhekeka, kwaye emva koko iphuhlise ukuya kuthi ga ngoku. umphezulu woqhagamshelwano, ukwenzela ukuba umaleko womphezulu we-metal flake ngaphandle, okukhokelela ekuthwaleni awukwazi ukusebenza ngokuqhelekileyo, le nto ibizwa ngokuba yi-fatigue spalling.Ukudinwa kokugqibela kwe-rolling bearings kunzima ukuyiphepha, enyanisweni, kwimeko yofakelo oluqhelekileyo, ukuthambisa kunye nokutywinwa, uninzi lomonakalo wokudinwa kukudinwa.Ke ngoko, ubomi benkonzo yeebheringi ngokuqhelekileyo bubizwa ngokuba bubomi benkonzo yokudinwa kweebheringi.
Ukuguqulwa kwePlastiki (utshintsho olusisigxina):
Xa i-rolling bearing iphantsi komthwalo ogqithisileyo, i-deformation yeplastiki ibangelwa kumzimba ojikelezayo kunye nokugqithisa kumnxibelelwano, kunye nokuqengqeleka kumphezulu kuvelisa i-dent, okubangelwa ukungcangcazela okukhulu kunye nengxolo ngexesha lokuqhuba ukuthwala.Ukongeza, amasuntswana angaphandle angaphandle kwi-bearing, umthwalo ogqithisiweyo wempembelelo, okanye xa ukuthwala kumile, ngenxa yokungcangcazela komatshini kunye nezinye izinto ezinokuvelisa indentation kumphezulu woqhagamshelwano.
Nxibela ukuyikrazula:
Ngenxa yentshukumo ehambelanayo yento eqengqelekayo kunye nomdyarho kunye nokuhlaselwa kokungcola nothuli, into eqengqelekayo kunye nokuqengqeleka kumphezulu kubangela ukuguga.Xa isixa sokunxiba sikhulu, ukuchaneka kokuthwala, ingxolo kunye nokungcangcazela kwanda, kwaye ukuchaneka kokuhamba kwe-bearing kuyancipha, ngoko kuchaphazela ngokuthe ngqo ukuchaneka kwezinye iinjini eziphambili.
Okwesine, inqanaba lokuchaneka lokuchaneka kunye nendlela yokumela ukucocwa kwengxolo
Ukuchaneka kweebheringi eziqengqelekayo kwahlulwe ngokuchaneka kwe-dimensional kunye nokuchaneka okujikelezayo.Umgangatho ochanekileyo ulungelelaniswe kwaye uhlukaniswe ngamanqanaba amahlanu: i-P0, i-P6, i-P5, i-P4 kunye ne-P2.Ukuchaneka kuphuculwe ukusuka kwinqanaba le-0, ngokumalunga nokusetyenziswa okuqhelekileyo kwinqanaba le-0 kwanele, ngokwemiqathango okanye iimeko ezahlukeneyo, umgangatho ofunekayo wokuchaneka awufani.
Emihlanu, edla ngokubuzwa imibuzo ethweleyo
(1) Ukuthwala intsimbi
Iintlobo eziqhelekileyo ezisetyenziswayo zokuqengqeleka intsimbi: high carbon complex ethwele intsimbi, carburized bearing steel, corrosion resistant steel, ubushushu obuphezulu bentsimbi.
(2) Ukuthambisa iibheringi emva kokufakwa
Ukuthambisa kwahlulwe ngokweendidi ezintathu: igrisi, ioli yokuthambisa, ukuthambisa okuqinileyo
I-Lubrication inokwenza ukuba i-bearing iqhube ngokuqhelekileyo, igweme ukudibanisa phakathi komdyarho kunye ne-rolling surface, ukunciphisa i-friction kunye nokugqoka ngaphakathi kwe-bearing, kunye nokuphucula ixesha lenkonzo yokuthwala.Igrisi inokubambelela kakuhle kunye nokumelana nokunxiba kunye nokumelana nobushushu, okunokuphucula ukuxhathisa kwe-oxidation yeebheringi zobushushu obuphezulu kunye nokuphucula ubomi benkonzo yeebheringi.Igrisi kwi-bearing akufanele ibe yinto eninzi, kwaye igrisi eninzi iya kuba yinto echaseneyo.Isantya esiphezulu sokuthwala, ingozi enkulu.Kuya kwenza ukuthwala ukusebenza xa ubushushu bukhulu, kuya kuba lula ukonakala ngenxa yobushushu obugqithisileyo.Ke ngoko, kubaluleke kakhulu ukuzalisa igrisi ngokwesayensi.
Isithandathu, sithwele imiqathango yofakelo
Ngaphambi kokufakela, qwa lasela ukuba ukhangele ukuba kukho ingxaki ngomgangatho wokuthwala, ukhethe ngokuchanekileyo isixhobo sokufakela esihambelanayo, kwaye ubeke ingqalelo ekucocekeni kokuthwala xa ufaka ukuthwala.Nika ingqalelo nokuba unyanzelise xa ucofa, ucofa ngobunono.Khangela ukuba iibheringi zifakwe ngokufanelekileyo emva kofakelo.Khumbula, ngaphambi kokuba umsebenzi wamalungiselelo ugqitywe, musa ukukhupha iintsimbi ukuthintela ukosuleleka.
