Spindle bearing vibration nyob rau hauv precision tshuab cuab yeej hais txog cov neeg kho tshuab kev co tshwm sim los ntawm lub unbalanced quab yuam thiab asymmetric load generated los ntawm spindle raws li nws rotates ntawm kev kub ceev. Qhov kev vibration no yuav ua rau muaj kev hnav ris tsho ntxiv, txo qhov raug thiab ruaj khov ntawm lub tshuab cuab yeej, thiab nyob rau hauv cov xwm txheej hnyav ua rau cov kabmob puas lossis lub tshuab tsis ua haujlwm.
Spindle bearing kev co feem ntau muab faib ua ob hom: radial kev co thiab axial kev co. Radial kev co feem ntau yog vim cov kabmob sab hauv thiab sab nraud ntawm qhov chaw tsis sib luag lossis centrifugal quab yuam tsis sib xws, tshwm sim los ntawm kev vibration zaus thiab spindle ceev yog proportional; axial kev co yog vim cov kabmob sab hauv cov qauv tsim lossis kev ua haujlwm raug tsis siab, qhov kev vibration zaus thiab spindle ceev yog inversely proportional.
Txhawm rau txo qhov kev vibration ntawm spindle bearing, cov kev ntsuas hauv qab no tuaj yeem ua:
1. kho cov kabmob preload kom ntseeg tau tias kev sib koom ua ke ntawm cov kabmob sab hauv ntawm cov kabmob thiab txo cov kev sib txhuam sab hauv thiab hnav ntawm cov kabmob.
2. xaiv lub siab precision bearings kom paub meej tias cov qauv sab hauv yog qhov tseeb thiab muaj peev xwm nqa tau zoo los txo qhov kev vibration thiab suab nrov ntawm cov bearings.
3. Dynamic ntsuas ntawm cov bearings kom tshem tawm cov quab yuam tsis sib npaug thiab thauj khoom hauv cov kabmob thiab txo qis kev vibration.
4. Precise adjustment ntawm mounting txoj hauj lwm thiab lub kaum sab xis ntawm spindle kom paub meej tias lub geometry ntawm spindle ua tau raws li qhov yuav tsum tau thiab txo kev co.
5. Txhim kho cov tshuaj tiv thaiv kev tiv thaiv los yog cov khoom siv nyiaj txiag kom them nyiaj rau cov tsis sib haum xeeb thiab kev thauj khoom asymmetric thaum lub sij hawm kev kub ceev ntawm lub spindle kom txo kev co thiab suab nrov.
