Fatigue dimples nyob rau hauv dov bearings vim muaj ntau yam zoo li qub loads zoo ib yam li dimples los ntawm txawv teb chaws hais, thiab lawv tsa sawv tuaj yeem ua rau tsis ua hauj lwm.Phenomenon: Nyob rau hauv thawj theem, cov pits faib nrog dov lub caij sib nrug feem ntau tsuas yog faib rau ib feem ntawm lub voj voog, uas nws thiaj li ua rau cov tsos ntawm cov kab nrib pleb.Qhov no qee zaum tshwm sim nrog tsuas yog ib qho ferrule.Feem ntau asymmetrical mus rau qhov chaw ntawm lub raceway.Ua rau: - Cov khoom zoo li qub ntau dhau, kev poob siab - Mounting rog kis tau los ntawm cov ntsiab lus dov Kev kho: - Ua raws li cov lus qhia kev teeb tsa - Tsis txhob overloads thiab overloads poob siab tshwm sim vim qhov tsis raug mounting: Rau angular contact pob bearings Feem ntau, muaj qaug zog nyob rau hauv qhov chaw tsis sib cuag nyob ze ntawm cov tav me me, saib daim duab 46. Ua rau: - Kev hloov kho tsis raug - Kev sib cuag tsis txaus axial lossis cov ntsia hlau xauv tsis nruj - Kev cuam tshuam ntau dhau ntawm radial cuam tshuam: - Xyuas kom nruj ntawm cov khoom nyob ib puag ncig - Txhim kho kev qaug zog vim tsis zoo : – Taug qab qhov chaw ntawm cov kabmob , saib daim duab 40 – Kev qaug zog ntawm cov kab sib tw / dov cov npoo, saib daim duab 47 – Circumferential grooves tshwm sim los ntawm cov yas deformation ntawm tag nrho lossis ib feem ntawm qhov chaw, yog li cov npoo yog du.Hauv qhov xwm txheej hnyav, yuav muaj cov kab nrib pleb hauv qab ntawm qhov zawj, saib daim duab 48.

Ua rau: Vim lub misalignment ntawm lub tsev los yog deflection ntawm lub ncej, lub nplhaib puab yog tilted txheeb ze rau lub nplhaib sab nrauv thiab ua rau lub sij hawm loj loads.Rau cov pob bearings, qhov no ua rau muaj zog hauv cov hnab ris hauv lub tawb (ntu 3.5.4), zawv zawg ntau dua ntawm cov kev sib tw thiab cov pob uas khiav ntawm cov npoo ntawm cov raceways.Rau cov menyuam bearings, lub raceway yog asymmetrically loaded.Thaum lub nplhaib yog inclined tiag tiag, ntug ntawm raceway thiab dov cov ntsiab lus yuav dais lub load, thiab kev ntxhov siab concentration yuav tshwm sim.Thov xa mus rau "Musalignment track" hauv tshooj 3.3.1.2.Kev ntsuas kev kho: - Siv cov bearings nws tus kheej - txo qis misalignment - txhim kho ncej zog 31 Ntsuas cov yam ntxwv ntawm kev khiav thiab kev puas tsuaj ntawm kev tshem tawm cov kabmob qaug zog.48: Kev qaug zog tshwm sim ntawm ntug ntawm lub pob bearing raceway, xws li nrog lub sijhawm siab loads (ntug khiav);daim duab sab laug qhia txog ntug ntawm txoj kev sib tw, thiab daim duab sab xis qhia lub pob.
