Kukho iintlobo ezininzi ezahlukeneyo zeebheringi ezikhoyo namhlanje kunye nolwazi oluncinci kakhulu malunga nomahluko phakathi kwabo.Mhlawumbi ukhe wazibuza ukuba "yeyiphi impembelelo eya kulunga kwisicelo sakho?"Okanye “ndingayikhetha njani ibhere?”Eli nqaku liza kukunceda uphendule loo mibuzo.
Okokuqala, kufuneka wazi ukuba uninzi lweebheringi ezinento eqengqelekayo ziwela kumaqela amabini abanzi:
Iibhodi zebhola
Iibheringi zeerola
Ngaphakathi kwala maqela, kukho izintlu ezingaphantsi zeebheringi ezineempawu ezizodwa okanye uyilo oluphuculweyo lokuphucula ukusebenza.
Kweli nqaku, siza kugubungela izinto ezine ekufuneka uzazi malunga nesicelo sakho ukuze ukhethe uhlobo olululo lokuthwala.
Fumana uMthwalo wokuThwala kunye nesakhono soMthwalo
Ukuthwala imithwalo ngokuqhelekileyo kuchazwa njengamandla okusabela abeka icandelo kwibheringi xa isetyenziswa.
Xa ukhetha uhlobo olufanelekileyo lwesicelo sakho, okokuqala kufuneka ufumane umthamo womthwalo wokuthwala.Umthamo womthwalo ngumthamo womthwalo onokuthi uphathe kwaye ungenye yezinto ezibalulekileyo xa ukhetha ukuthwala.
Ukuthwala imithwalo ingaba yi-axial (i-thrust), i-radial okanye indibaniselwano.
I-axial (okanye i-thrust) ethwele umthwalo kuxa amandla ahambelana ne-axis ye-shaft.
Umthwalo wokuthwala i-radial kuxa amandla e-perpendicular kwi-shaft.Emva koko umdibaniso wokuthwala umthwalo kuxa i-parallel and perpendicular forces ivelisa amandla e-angular ngokubhekiselele kwi-shaft.
Indlela iiBearings zeBhola ezisasaza ngayo imithwalo
Iibheringi zebhola ziyilwe ngeebhola ezingqukuva kwaye zinokusasaza imithwalo kwindawo enobungakanani obuphakathi.Badla ngokusebenza ngcono kwimithwalo emincinci ukuya kwephakathi, besasaza imithwalo ngendawo enye yoqhagamshelwano.
Apha ngezantsi kukho ireferensi ekhawulezayo yohlobo lomthwalo othweleyo kunye neyona bhola ingcono kakhulu yomsebenzi:
I-Radial (i-perpendicular to shaft) kunye nemithwalo elula: Khetha ii-radial ball bearings (ekwaziwa ngokuba yi-deep groove ball bearings).Iibheringi zeradial zezinye zezona ntlobo zixhaphakileyo zeebheringi kwimarike.
I-Axial (i-thrust) (inxusene neshaft) imithwalo: Khetha iibheringi zebhola
Idityanisiwe, zombini i-radial kunye ne-axial, imithwalo: Khetha i-angular contact beararing.Iibhola ziqhagamshela indlela yomdyarho kwi-engile exhasa ngcono imithwalo edibeneyo.

I-Axial (i-thrust) (ingqamene neshaft) imithwalo: Khetha iibheringi ze-cylindrical thrust
Idibaniswe, zombini i-radial kunye ne-axial, imithwalo: Khetha i-taper roller bear
Izantya zokujikeleza
Isantya sokujikeleza kwesicelo sakho yinto elandelayo ekufuneka uyijongile xa ukhetha ukuzala.
Ukuba isicelo sakho siya kusebenza ngesantya esiphezulu sokujikeleza, ngoko ke iibheringi zebhola zikholisa ukuba lolona khetho lukhethwayo.Benza ngcono kwizantya eziphezulu kwaye banikezela ngesantya esiphakamileyo kuneebheringi eziqengqelekayo.
Esinye isizathu kukuba uqhagamshelwano phakathi kwento eqengqelekayo kunye ne-raceways kwibhola yebhola yindawo endaweni yomgca woqhagamshelwano, njengakwii-roller bearings.Ngenxa yokuba izinto eziqengqelekayo zicinezela kwindlela yomdyarho njengoko ziqengqeleka ngaphezulu komphezulu, kukho uguquko oluncinci lomphezulu olwenzeka kumthwalo wenqaku ukusuka kwiibheringi zebhola.
Umkhosi we-Centrifugal kunye neeBearings
Esinye isizathu sokuba ibhola ibengcono kwizicelo zesantya esiphezulu kungenxa yemikhosi ye-centrifugal.Amandla e-Centrifugal achazwa njengamandla atyhala ngaphandle kumzimba ojikeleza iziko kwaye avela ku-inertia yomzimba.
Amandla e-Centrifugal yeyona nto iphambili ethintela ukuthwala isantya kuba ijika ibe yimithwalo yeradial kunye ne-axial kwibheringi.Ekubeni iibheringi ze-roller zinobunzima obuninzi kunebhola, i-roller bearing iya kuvelisa amandla aphezulu e-centrifugal ngaphezu kwebhola elinobukhulu obufanayo.
Nciphisa i-Centrifugal Force nge-Ceramic Balls Material
Ngamanye amaxesha isantya sesicelo singaphezulu kwereyithingi yesantya somdlalo webhola.
Ukuba oku kwenzeka, isisombululo esilula kunye nesiqhelekileyo kukutshintsha izinto ezithwala ibhola kwintsimbi ukuya kwi-ceramic.Oku kugcina ubungakanani bokuthwala bufana kodwa kubonelela ngokumalunga ne-25% yokulinganisa isantya esiphezulu.Ekubeni izinto ze-ceramic zilula kunentsimbi, iibhola ze-ceramic zivelisa amandla angaphantsi kwe-centrifugal nakwesiphi na isantya.
Izicelo ze-Speed High-Speed Work Best kunye ne-Angular Contact Bearings
Iibheringi zoqhagamshelwano lwe-angular lolona khetho lubalaseleyo lokuthwala usetyenziso olunesantya esiphezulu.Esinye isizathu kukuba iibhola zincinci kwaye iibhola ezincinci zinobunzima obuncinci kwaye zivelisa amandla angaphantsi kwe-centrifugal xa zijikeleza.Iibheringi zoqhagamshelwano ze-angular nazo zine-preload eyakhelwe-ngaphakathi kwiibheringi ezisebenza kunye nemikhosi ye-centrifugal ukuqengqeleka ngokufanelekileyo iibhola ekuthwaleni.
Ukuba uyila isicelo esinesantya esiphezulu, ngoko uya kufuna ukuchaneka okuphezulu, ngokuqhelekileyo ngaphakathi kweklasi yokuchaneka kwe-ABEC 7.
Ukuchaneka okusezantsi “kunegumbi le-wiggle” xa lenziwe kunomgangatho ophezulu wokuchaneka.Ke ngoko, xa ibherethi isetyenziswa ngesantya esiphezulu, iibhola ziqengqeleka ngokukhawuleza ngaphaya komdyarho wokuzala ngokuthembeka okuncinci okunokukhokelela ekungaphumelelini kokuthwala.
Iibheringi ezichanekileyo eziphezulu zenziwe ngemigangatho engqongqo kwaye zineenxa ezincinci kakhulu kwi-specs xa ziveliswa.Iibheringi ezichanekileyo ezichanekileyo zithembekileyo kwizicelo ezihamba ngokukhawuleza kuba ziqinisekisa ibhola elihle kunye nokusebenzisana komzila.
Ukuthwala Ukuphela kunye noBungqongqo
Ukuthwala i-ruout yimali ejikelezayo i-shaft ukusuka kumbindi wayo wejometri njengoko ijikeleza.Ezinye izicelo, njengesixhobo sokusika izixhobo zokuphotha, ziyakuvumela kuphela ukutenxa okuncinci ukuba kwenzeke kumalungu ajikelezayo.
Ukuba uyinjineli isicelo esifana nesi, ke khetha ukuchaneka okuphezulu ngenxa yokuba iya kuvelisa inkqubo encinci yokuqhuba ngenxa yokunyamezelana okuqinileyo okwenziweyo.
Ukuthwala ukuqina kukumelana namandla okwenza ukuba i-shaft iphambuke kwi-axis yayo kwaye idlala indima ephambili ekunciphiseni ukuphuma kwe-shaft.Ukuthwala ukuqina kuvela ekusebenzisaneni kwento eqengqelekayo kunye nomdyarho.Okukhona i-element eqengqelekayo icinezelwe kwindlela yomdyarho, ibangela i-elastic deformation, kokukhona i-rigidity iphakama.
Ukuthwala ukuqina kudla ngokuhlelwa ngolu hlobo:
Ukuqina kwe-axial
Ukuqina kweRadial
Ukuphakama kokuqina kokuthwala, kokukhona kufuneka amandla angakumbi okuhambisa i-shaft xa isetyenziswa.
Makhe sijonge ukuba oku kusebenza njani ngokuchaneka kweebheringi zoqhagamshelwano oluyi-angular.Ezi bheringi zidla ngokuza ne-offset eyenziweyo phakathi kwendlela yangaphakathi nangaphandle yomdyarho.Xa iibheringi zoqhagamshelwano ze-angular zifakiwe, i-offset iyasuswa, nto leyo ebangela ukuba iibhola zicinezele kwi-raceway ngaphandle kwamandla okusebenza angaphandle.Oku kubizwa ngokuba kukulayishwa kwangaphambili kwaye inkqubo yonyusa ukuthwala ubulukhuni naphambi kokuba ukuthwala kubone nayiphi na imikhosi yesicelo.
Ukuthwala iLubrication
Ukwazi iimfuno zakho zokuthambisa ezithwele kubalulekile ekukhetheni iibheringi ezifanelekileyo kwaye kufuneka ziqwalaselwe kwangoko kuyilo lwesicelo.Ukuthambisa okungafanelekanga sesinye sezona zizathu zixhaphakileyo zokungaphumeleli kokuthwala.
Ukuthambisa kudala ifilimu yeoli phakathi kwento eqengqelekayo kunye nogqatso lomdyarho onceda ukuthintela ukungqubana kunye nobushushu obugqithisileyo.
Olona hlobo luqhelekileyo lokuthambisa igrisi, oluqulethwe yioyile ene-ejenti yokuqina.I-ejenti yokuqina igcina ioli kwindawo, ngoko ayiyi kushiya ukuthwala.Njengoko ibhola (ukuthwala ibhola) okanye i-roller (i-roller bearing) iqengqeleka phezu kwegrisi, i-agent ejiyayo iyahlula ishiya nje ifilimu yeoli phakathi kwendawo eqengqelekayo kunye nomzila wokubaleka.Emva kokuba i-element eqengqelekayo idlula, i-oyile kunye ne-ejenti yokuqina idibanisa kunye.
Ukusetyenziswa kwesantya esiphezulu, ukwazi isantya apho ioli kunye ne-thickener inokwahlula kwaye idibanise kwakhona kubalulekile.Oku kubizwa ngokuba sisicelo okanye ukuthwala ixabiso le-n*dm.
Phambi kokuba ukhethe igrisi, kufuneka ufumane usetyenziso lwakho ndm ixabiso.Ukwenza oku phinda-phinda izicelo zakho ze-RPMs ngedayamitha yombindi weebhola kwibheringi (dm).Thelekisa ixabiso lakho le-ndm kwisantya esiphezulu sexabiso legrisi, elibekwe kuluhlu lwedatha.
Ukuba ixabiso lakho le-n*dm liphezulu kunexabiso lesantya esiphezulu segrisi kwi-database, igrisi ayizukwazi ukubonelela ngokuthambisa okwaneleyo kunye nokusilela kwangaphambi kwexesha kuya kwenzeka.
Olunye ukhetho lokuthambisa kwizicelo ezinesantya esiphezulu zizixokelelwano zenkungu ye-oyile ezixuba i-oyile nomoya oxinanisiweyo ze emva koko iwufake kumgaqo wokubaleka ngemitha.Olu khetho lubiza kakhulu kune-lubrication yegrisi kuba ifuna umxube wangaphandle kunye nenkqubo yokulinganisa kunye nomoya oxilisiweyo ohluziweyo.Nangona kunjalo, iinkqubo zenkungu ye-oyile zivumela iibheringi ukuba zisebenze ngesantya esiphezulu ngelixa zivelisa ubushushu obuphantsi kuneebheringi ezigcotyiweyo.
Ukusetyenziswa kwesantya esisezantsi ibhafu yeoli ixhaphakile.Ukuhlamba i-oyile kuxa inxalenye yokuthwala ifakwe kwioli.Kwiibheringi eziya kusebenza kwiimeko ezigqithisileyo, isithambisi esomileyo sinokusetyenziswa endaweni yesithambiso esekwe kwipetroleum, kodwa ubomi bokuthwala bufutshane ngenxa yendalo yefilimu yesithambiso esophuka ekuhambeni kwexesha.Kukho ezinye izinto ezimbalwa ekufuneka ziqwalaselwe xa ukhetha i-lubricant kwisicelo sakho, jonga inqaku lethu elinzulu "Yonke into okufuneka uyazi malunga nokuBeka iLubrication.
