1 Ukumelana nokunxiba okuphezulu

Xa i-rolling bearing isebenza ngokuqhelekileyo, ngaphezu kwe-rolling friction, ikwahamba kunye ne-sliding friction.Ezona ndawo ziphambili zokukhuhlana kwe-sliding zezi: indawo yokudibanisa phakathi kwento eqengqelekayo kunye ne-raceway, indawo yokudibanisa phakathi kwento eqengqelekayo kunye nepokotho yekheji, phakathi kwekheji kunye nombambo wesikhokelo seringi, kunye ne-roller end surface kunye ne-ring guide Linda. phakathi kweendonga.Ubukho bokutyibilika kokutyibilika kwiibheringi eziqengqelekayo ngokungenakuthintelwa kubangela ukuguga kweenxalenye ezithweleyo.Ukuba ukunyanzeliswa kokugqoka kwentsimbi yentsimbi kubi, ukunyathela okuqengqelekayo kuya kulahlekelwa ukuchaneka kwangaphambi kwexesha ngenxa yokugqoka okanye ukunciphisa ukuchaneka kokujikeleza, okuya kwandisa ukunyakaza kwentsimbi kunye nokunciphisa ubomi bayo.Ngoko ke, intsimbi yokuthwala iyadingeka ukuba ibe nokuchasana okuphezulu.

2Amandla okudinwa okuphezulu

Ukungaphumeleli kokudinwa koqhagamshelwano yindlela ephambili yokungaphumeleli kokuthwala okuqhelekileyo.Xa i-rolling bearing isebenza, izinto eziqengqelekayo ziqengqeleka phakathi kweendlela zomdyarho zamakhonkco angaphakathi nangaphandle, kwaye inxalenye yoqhagamshelwano ithwala imithwalo etshintshanayo ngamaxesha athile, enokufikelela kumakhulu amawaka amaxesha ngomzuzu.Ngaphantsi kwesenzo esiphindaphindiweyo soxinzelelo lwexesha lokutshintshana, indawo yoqhagamshelwano I-Fatigue peeling iyenzeka.Xa i-rolling bear iqala ukukhupha, iya kubangela ukuba i-bearing ishukume kwaye inyuse ingxolo.Ukushisa okusebenzayo kuya kuphakama ngokukhawuleza, kubangela ukuba ukuthwala konakaliswe.Olu hlobo lomonakalo lubizwa ngokuba yi-contact fatigue damage.Ke ngoko, intsimbi yeebheringi eziqengqelekayo ifuneka ukuba ibe namandla okudinwa okuphezulu.

3 umda ophezulu we-elastic

Xa i-rolling bearing isebenza, kuba indawo yoqhagamshelwano phakathi kwento ejikelezayo kunye ne-raceway yendandatho incinci, uxinzelelo loqhagamshelwano kwindawo yoqhagamshelwano lukhulu kakhulu xa ukuthwala kuphantsi komthwalo, ngakumbi xa kuphantsi komthwalo omkhulu.Ukuze kuthintelwe i-deformation yeplastiki egqithisileyo phantsi koxinzelelo oluphezulu loqhagamshelwano, ukulahleka kokuchaneka kokuchaneka okanye ukuqhekeka kwendawo, intsimbi yokuthwala iyadingeka ukuba ibe nomda ophezulu we-elastic.

4 ubulukhuni obufanelekileyo

Ubunzima sesinye sezibonakaliso ezibalulekileyo zeebheringi eziqengqelekayo.Inobudlelwane obusondeleyo kunye namandla okudinwa kwezinto eziphathekayo, ukumelana nokunxiba, kunye nomda we-elastic, kwaye ichaphazela ngqo ubomi beebheringi eziqengqelekayo.Ubunzima bokuthwala ngokuqhelekileyo buchongwa yimeko yonke yendlela yomthwalo wokuthwala kunye nobukhulu, ubukhulu becala kunye nobukhulu bodonga.Ubunzima bentsimbi yokuthwala i-rolling kufuneka bufaneleke, inkulu kakhulu okanye incinci kakhulu iya kuchaphazela ubomi benkonzo yokuthwala.Njengoko sonke sisazi, iindlela eziphambili zokungaphumeleli kweebherethi eziqengqelekayo zidibene nomonakalo wokudinwa kunye nokulahleka kokuchaneka kokuchaneka ngenxa yokunganyangeki kokunxiba okanye ukungazinzi komda;ukuba iinxalenye ezithweleyo ziswele iqondo elithile lokuqina, ziya kubangelwa kukuphuka kwe-brittle xa ziphantsi kwemithwalo yempembelelo enkulu.Ukutshatyalaliswa kwebheringi.

Ngoko ke, ubunzima bokuthwala kufuneka bunqunywe ngokwemeko ethile yokuthwala kunye nendlela yomonakalo.Ukulahleka kokuchaneka kokuchaneka ngenxa yokudinwa okanye ukunganyangeki kokunxiba, ubunzima obuphezulu kufuneka bukhethwe kwiindawo zokuthwala;iibheringi ezixhomekeke kwimithwalo yempembelelo emikhulu (ezifana nee-rolling Mills: iibheringi, iibheringi zikaloliwe kunye nezinye iibheringi zeemoto, njl. njl.), kufuneka zincitshiswe ngokufanelekileyo Ubulukhuni buyimfuneko ekuphuculeni ukuqina kokuthwala.

5 ukuqina kwempembelelo ethile

Iibherethi ezininzi eziqengqelekayo ziya kulawulwa ngumthwalo othile wempembelelo ngexesha lokusetyenziswa, ngoko ke intsimbi yokuthwala iyadingeka ukuba ibe nokuqina okuthile ukuqinisekisa ukuba ukuthwala akonakali ngenxa yempembelelo.Kwiibheringi ezimelana nemithwalo yempembelelo enkulu, enje ngeebheringi zokungqusha, iibheringi zikaloliwe, njl. njl., imathiriyeli iyafuneka ukuba ibe nokuqina kwempembelelo ephezulu kunye nokuqina kokwaphuka.Ezinye zezi bheringi zisebenzisa inkqubo yokucima ubushushu obukhethekileyo, kwaye ezinye zisebenzisa izixhobo zentsimbi ekhatywayo.Qinisekisa ukuba ezi bheringi zinempembelelo entle yokuchasa.

6 Uzinzo olulungileyo lwe-dimensional

Iibheringi eziqengqelekayo ziindawo ezichanekileyo zomatshini, kwaye ukuchaneka kwazo kubalwa kwii-micrometers.Kwinkqubo yokugcinwa kwexesha elide kunye nokusetyenziswa, utshintsho kwintlangano yangaphakathi okanye utshintsho kwixinzelelo luya kubangela ukuba utshintsho kubukhulu bokuthwala, okukhokelela ekulahlekeni kokuchaneka kokuthwala.Ngoko ke, ukwenzela ukuba kuqinisekiswe ukuchaneka kwe-dimensional ye-bearing, intsimbi yokuthwala kufuneka ibe nokuzinza okuhle kwe-dimensional.

7 Ukusebenza kakuhle kokuchasana nomhlwa

Iibheringi eziqengqelekayo zineenkqubo ezininzi zokuvelisa kunye nomjikelo omde wemveliso.Ezinye iindawo ezigqityiweyo okanye ezigqityiweyo kufuneka zigcinwe ixesha elide ngaphambi kokuhlanganisana.Ngoko ke, iinxalenye ezithweleyo zixhomekeke kwinqanaba elithile lokubola ngexesha lenkqubo yokuvelisa okanye ekugcinweni kweemveliso ezigqityiweyo: ngakumbi Kukumoya omanzi.Ngoko ke, intsimbi yokuthwala iyadingeka ukuba ibe nokumelana nokugqwala okulungileyo.

8 Ukusebenza kakuhle kwenkqubo

Kwinkqubo yokuvelisa iibheringi eziqengqelekayo, iinxalenye zayo kufuneka zihambe ngeendlela ezininzi ezibandayo nezishushu.Oku kufuna ukuba intsimbi yokuthwala ifanele ibe neepropati ezintle zenkqubo, njengezinto ezibandayo kunye nezishushu zokwenza izinto, ukusika, ukugaya ukusebenza kunye nokusebenza kokushisa ukushisa, njl., Ukuhlangabezana neemfuno zobunzima bokuthwala, ukusebenza kakuhle, ixabiso eliphantsi kunye nomgangatho ophezulu wemveliso. .

Ukongeza, kwiibherengi ezisetyenziswa phantsi kweemeko ezikhethekileyo zokusebenza, ukongeza kwiimfuno ezisisiseko ezikhankanywe ngasentla, iimfuno ezihambelanayo zokusebenza ezihambelanayo kufuneka zibekwe phambili kwintsimbi esetyenzisiweyo, njengokumelana nobushushu obuphezulu, ukusebenza ngesantya esiphezulu, ukuxhathisa ukubola kunye nokusebenza kwe-antimagnetic.
