INyaniso malunga ne-High-Speed ​​Bearings ye-CNC Spindles

INyaniso malunga ne-High-Speed ​​Bearings: Impendulo eKhawulezayo

I-high-speed bearing ayikuko nje ukuthwala ngenani elikhulu le-RPM kwi-database. Kwi-spindle ye-CNC, isantya esisebenzisekayo sixhomekeke kwindlela epheleleyo yokuthwala: ubungakanani bokuthwala, i-rolling-element material, uyilo lwangaphakathi, i-angle yoqhagamshelwano, ukulayisha kwangaphambili, ukulungiswa, iklasi yokuchaneka, indlela yokuthambisa, ukulingana, ukupholisa, umthwalo, ukulawula ukungcola, kunye nokuziphatha kwe-spindle thermal.

Kungenxa yoko le nto iibheringi ezimbini ezinemilinganiselo efanayo zinokuba nesantya esahlukileyo kakhulu, ukunyuka kwamaqondo obushushu, ukuqina, ingxolo, kunye nobomi benkonzo. Kwakhona kutheni i-bearing eqhuba kakuhle kwi-24,000 RPM kwi-spindle enye isenokungafaneleki isantya esifanayo kwi-spindle enkulu, elayishwe kakhulu, eyahlukileyo eyahlukileyo.

I-key takeaway: vavanya iibheringi zokusonta ezinesantya esiphezulu njengenxalenye yenkqubo. Ubuninzi be-RPM ligalelo elinye kuphela. Isantya, ukulayisha kwangaphambili, ukuthambisa, ukuzinza kwe-thermal, ukuqina, umthamo womthwalo, ilungiselelo lokuthwala, kunye nomgangatho wofakelo kugqiba ukuba ukuthwala kunokusebenza ngokuthembekileyo kwi-spindle yangempela.

Buza malunga noKhetho lwe-Spindle lwe-CNC

Ziziphi iiBearings ezinesantya esiphezulu?

Iibheringi ezinesantya esiphezulu zithwele uyilo olulungiselelwe ukusebenza ngesantya esiphakamileyo esijikelezayo ngelixa ulawula ukukhuhlana, ukuveliswa kobushushu, iziphumo ze-centrifugal, ukuziphatha kokuthambisa, ukungcangcazela, kunye nokubaleka ngokuchanekileyo. Kumatshini-isixhobo kunye nezicelo ze-spindle ze-CNC, ezona zisombululo zixhaphake ngesantya esiphezulu zibandakanya ukuchaneka okuphezulu kwe-angular ball bearings , edla ngokunikezelwa njengeesethi ezihambelanayo kunye nokulayishwa kwangaphambili okuchaziweyo.

Ngokuxhomekeke kwi-architecture ye-spindle, i-speed-speed angular ball bearings inokudibaniswa kunye ne-cylindrical roller bearings okanye ezinye iintlobo zokuthwala ukubonelela ngebhalansi efunekayo yokuxhaswa kwe-radial, ukuxhaswa kwe-axial, ukuqina, amandla okwandisa i-thermal, kunye nesantya.

Kutheni i-RPM yodwa iyiMetriki yokuthelekisa engalunganga

I-20 mm ephethe i-20 mm eqhuba kwi-30,000 RPM kunye ne-80 mm ephethe i-30,000 RPM ayifumani imeko efanayo yesantya. Ibheringi enkulu inesantya esiphezulu se-rolling-element kunye nefuthe le-centrifugal. Ngesi sizathu, iinjineli zokuthwala zihlala zisebenzisa iparamitha yesantya esekwe kwisantya sokujikeleza kunye nokuthwala i-diameter.

Umba wesantya = n × d _m

apho n = isantya sokujikeleza kwi-r/min

d _m = (d + D) ÷ 2 , apho i-d ithwele i-bore diameter kunye no-D ngaphandle kwedayamitha nge-mm.

Ixabiso le-n × d _m liluncedo ekuthelekiseni ubukhali besantya, kodwa iseyiyo yonke indlela yokupasa/yokusilela. Ixabiso elivumelekileyo lixhomekeke kuthotho lokuthwala, ikheji, imathiriyeli yebhola, ukulayishwa kwangaphambili, ukuthambisa, ukususwa kobushushu, umthwalo, ukulingana, kunye nedatha yoyilo lomenzi.

Imiba emi-6 eyiNqanaba eQinisekisayo ngokuSebenza okuPhakamileyo

1. Ubungakanani boBume kunye nejometri yangaphakathi

Izinto ezincinci eziqengqelekayo kunye nejometri yangaphakathi ephuculweyo inokunciphisa amandla e-centrifugal kunye nokukhuhlana ngesantya esiphezulu. Nangona kunjalo, ukunciphisa ubungakanani bebhola kunokutshintsha umthamo womthwalo kunye nokuqina.
