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.Bearing sticks ob peb zaug, saib daim duab 77. Lub hardness yog qis dua 58HRC.Yog vim li cas: Ua tsis tiav ntawm bearings vim overheating feem ntau tsis pom lawm.Tej yam ua tau: - Kev khiav hauj lwm ntawm cov kabmob me dhau, tshwj xeeb tshaj yog nyob rau hauv kev kub ceev - Tsis txaus lubrication - Radial preload vim los ntawm lwm qhov chaw tshav kub - lubricant ntau dhau - impeded lag luam vim lub tawb pob txha kho: - Nce Bearing Clearance - Yog hais tias muaj ib tug Cov cua kub sab nraud, xyuas kom qeeb cua sov thiab cua txias, piv txwv li cov cua sov tsis sib xws ntawm tag nrho cov kab bearings - Tsis txhob muaj roj nplua nyeem - Txhim kho lubrication 47 Ntsuas cov yam ntxwv ntawm kev khiav thiab kev puas tsuaj ntawm cov bearings dismantled.

Hu rau hom 77 ntawm Rolling Bearings: Overheated FAG Cylindrical Cov Menyuam Bearings nrog Deep Adhesive Indentations ntawm Rollers ntawm Raceways.*) 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.

Bearing scratches: Rau cov cylindrical roller bearings sib cais los yog tapered cov menyuam bearings, muaj cov khoom uas ploj lawm los ntawm dov cov ntsiab lus thiab raceways uas yog parallel mus rau lub axis thiab equidistant los ntawm dov ntsiab.Qee lub sij hawm muaj ob peb txheej ntawm cov cim nyob rau hauv cov kev taw qhia circumferential.Cov kab no feem ntau pom tsuas yog nyob rau hauv qhov kev taw qhia ncig ntawm B / d es tsis yog tag nrho cov ncig, saib daim duab 76. Ua rau: Kev sib tsoo thiab sib tsoo sib tsoo thaum txhim kho ib qho ferrule thiab lub ferrule nrog dov cov ntsiab lus.Nws yog qhov txaus ntshai tshwj xeeb tshaj yog thaum txav cov khoom loj loj (thaum cov ncej tuab nrog cov kabmob puab lub nplhaib thiab cov khoom sib dhos yog thawb rau hauv lub nplhaib sab nraud uas twb tau teeb tsa hauv cov kabmob vaj tse).Kev Kho: - Siv cov cuab yeej tsim nyog - Zam kev tsis raug - ​​yog tias ua tau, tig maj mam thaum txhim kho cov khoom.
