Thaum koj nug tus qauv bearing, peb feem ntau pom ob qho kev xaiv ntawm CR thiab COR. Ob tsab ntawv no sawv cev li cas? CR yog hais txog cov kabmob rated load, thiab COR yog hais txog cov kabmob static load. Yog li dab tsi yog qhov bearing static load thiab rated dynamic load? Qhov sib txawv thiab qhov txawv ntawm ob yog dab tsi? Qhia raws li nram no:
Peb qhov kev tsis sib haum xeeb feem ntau siv rau hauv cov kabmob dov hauv kev tsim yog: qhov yooj yim ruaj khov -rate load CR (radial) lossis CA (axial direction) uas ua tau raws li qhov yuav tsum tau muaj ntawm lub neej qaug zog; Kev taw qhia ntawm) lossis COA (axial kev taw qhia) thiab qhov txwv ceev NO ntawm cov kabmob coj.
Dab tsi yog qhov bearing rated static load?
Basic rated static load (radial COR, axial COA) ntawm qhov yooj yim rated static load ntawm dov bearing yog hais txog kev sib piv nrog lub cheeb ntawm lub load los yog central axis static load thaum lub siab tshaj plaws load rau cov menyuam thiab cov menyuam sib cuag chaw ua rau kev sib cuag nrog kev ntxhov siab nyob rau hauv nruab nrab ntawm lub load. cov menyuam.
Qhov ntsuas static load yog txiav txim raws li qhov hypothetical load tej yam kev mob. Rau cov kev taw qhia kev coj tus kheej, qhov ntsuas zoo li qub yog hais txog cov khoom radial. Radial tivthaiv, thrust bearing yog hais txog lub hauv paus axial load.
Uas yog hais, radial rated load thiab axial hauv paus ntawm lub hauv paus axial ntawm cov kabmob ntawm cov kabmob ntawm cov kabmob ntawm cov kabmob.
Cov kabmob muaj peev xwm ntawm qhov sib sib zog nqus groove pob bearings thaum zoo li qub lossis qeeb kev sib hloov (ceev N Tsawg dua lossis sib npaug li 10R / min) yog qhov ntsuas zoo li qub.
Dab tsi yog qhov bearing dynamic load?
Cov kabmob rated load yog hais txog qhov theoretical tas li radial load (stant axial load) uas cov kabmob dov tuaj yeem ua tau raws li txoj cai. Lub hauv paus ntsuas lub neej ntawm lub load yog 100W. Muaj peev xwm. Basic fixed-rate loads ntawm lub PC thiab thrust bearing yog hu ua radioprotic radical dynamic load thiab axial yooj yim tsau -rate load, uas yog sawv cev los ntawm CR thiab CA.
The bearing capacity of the ditch bearing when rotating (speed n>10r/mim) yog qhov yooj yim taag -rate load.
Vim li cas cov kabmob rated load ntau dua li qhov ntsuas static load?
Qhov ntsuas dynamic load yog hais txog cov load uas cov bearings dais thaum lub neej nyob yog 1 lab. Qhov ntsuas zoo li qub yog hais txog qhov sib npaug ntawm cov dov band nrog qhov loj tshaj plaws load thiab txoj kev dov nyob rau hauv txoj kab dov hauv qab no load. Qhov tseem ceeb
Cov kev pab cuam lub neej ntawm cov kabmob muaj qee qhov kev sib raug zoo nrog cov kabmob rated load. Peb tuaj yeem xaiv cov kabmob los ntawm cov kabmob rated load los ntawm cov kabmob rated load? Feem ntau muaj cov ntsiab lus hauv qab no:
Lus Cim: Qee zaum, qhov loj ntawm cov bearings yuav tsum raug xaiv los ntawm qhov ntsuas qhov zoo li qub (rau kev piav qhia yooj yim, txhais cov lej ntawm CO), es tsis suav cov kabmob ntawm cov kabmob.
1. Nyob rau hauv qhov kev txiav txim ntawm nruam los yog cuam tshuam kev thauj khoom, bearings tseem.
2. Nyob rau hauv qhov kev txiav txim ntawm kev thauj khoom, cov bearings tsuas yog maj mam viav vias lossis tswj kev ua haujlwm.
3. Nyob rau hauv qhov kev txiav txim ntawm kev thauj khoom, qhov ceev ntawm cov kabmob yog tsawg heev (tsawg dua 10 rpm ib feeb) thiab tsuas yog lub neej luv. Tshwj xeeb, nyob rau hauv cov ntaub ntawv no, rau ib tug muab sib npaug load P, lub hauv paus rated taag -rate load C, uas yog tsawg heev raws li lub neej formula, yog li ntawd, cov xaiv bearing tej zaum yuav hnyav heev overloaded nyob rau hauv tiag tiag ua hauj lwm.
4. Ntxiv rau qhov ua haujlwm ib txwm ua haujlwm, peb kuj yuav tsum tau ris lub nra hnyav. Cov kabmob yog tig.
Hauv ntau qhov xwm txheej saum toj no, qhov kev thauj khoom uas cov kabmob tuaj yeem tiv taus tsis yog nyob ntawm qhov qaug zog ntawm cov khoom siv, tab sis nyob ntawm seb qhov deformation mus tas li los ntawm kev thauj khoom ntawm lub load.
