Kev puas tsuaj rau dov bearings vim overheating: loj discoloration ntawm bearing Cheebtsam *).Lub raceway / dov caij yas deformation yog qhov hnyav.Qhov kub hloov pauv sai heev.FAG bearing tau daig ob peb zaug, saib daim duab 77. Lub hardness qis dua 58HRC.Yog vim li cas: Ua tsis tiav ntawm bearings vim overheating feem ntau tsis pom lawm.Tej yam ua tau: - Kev ua haujlwm tshem tawm ntawm cov kabmob me dhau, tshwj xeeb tshaj yog nyob rau hauv high speeds - lubrication tsis txaus - Radial preload vim los ntawm lwm qhov chaw tshav kub - lubricant ntau dhau - impeded lub lag luam vim lub tawb tawg.

Kev ntsuas kev kho: - Ua kom cov kabmob tshem tawm - Yog tias muaj qhov cua sov sab nraud, xyuas kom cov cua sov qeeb thiab txias, piv txwv li cov cua sov ntawm tag nrho cov kabmob - Tsis txhob muaj roj nplua nyeem - Txhim kho lubrication Tiv tauj Hom 77: Overheated cylindrical roller bearing nrog sib sib zog nqus nplaum indentations ntawm raceways ntawm rollers.*) Kev piav qhia ntawm kev hloov xim: Thaum cov kabmob siv rau cov xim tempered, nws muaj feem xyuam rau overheating.Cov tsos ntawm xim av thiab xiav yog txuam nrog qhov kub thiab txias thiab lub sij hawm ntawm overheating.Qhov tshwm sim no zoo ib yam li cov xim ntawm cov roj lubricating vim nws qhov kub thiab txias (saib tshooj 3.3.1.1).Yog li ntawd, nws tsis tuaj yeem txiav txim siab seb qhov kev khiav hauj lwm kub siab dhau los ntawm qhov tsis muaj xim.Nws tuaj yeem raug txiav txim los ntawm thaj chaw discoloration seb nws yog tshwm sim los ntawm tempering los yog roj: qhov kawg feem ntau tsuas yog tshwm sim nyob rau hauv lub load-bearing cheeb tsam ntawm dov cov ntsiab lus thiab rings, thiab yav tas los feem ntau npog thaj tsam loj ntawm lub bearing nto.Txawm li cas los xij, tsuas yog kev ntsuas ntsuas rau qhov muaj lossis tsis muaj kev ua haujlwm kub kub yog kev sim hardness.
