Kukhazikika kwamafuta, kukana kwa okosijeni ndi kutentha kwambiri ziyenera kuganiziridwa posankha mafuta opangira kutentha kwambiri.Muzogwiritsira ntchito zosakanizidwa, kumene kutentha kumagwira ntchito pamwamba pa 121 ° C, ndikofunika kusankha mafuta oyeretsedwa a mchere kapena mafuta opangira okhazikika monga mafuta oyambira.Table 28. Magulu a kutentha kwa mafuta Owononga Tinthu tating'onoting'ono tomwe timatulutsa tinthu tating'onoting'ono timagwira ntchito pamalo oyera, gwero lalikulu la kuwonongeka ndikutopa kwa malo olumikizirana.Komabe, kuipitsidwa kwa tinthu ting'onoting'ono kukalowa m'njira yoberekera, kumatha kuwononga monga ndulu, chodabwitsa chomwe chimachepetsa kubala moyo.Kuvala kumatha kukhala chifukwa chachikulu chowonongera zinthu pamene zonyansa m'chilengedwe kapena zitsulo zazitsulo pazinthu zina zomwe zimagwiritsidwa ntchito zimayipitsa mafuta.Ngati, chifukwa cha kuipitsidwa kwa tinthu tating'onoting'ono tamafuta, kuvala kwamafuta kumakhala kofunikira, miyeso yowoneka bwino imatha kusintha, zomwe zingakhudze magwiridwe antchito a makina.

Ma bearings omwe amagwira ntchito m'mafuta oipitsidwa amakhala ndi mavalidwe apamwamba kwambiri poyambira mafuta kuposa mafuta osakhudzidwa.Komabe, kuchuluka kwa kuvala kumeneku kumachepa mofulumira pamene palibe kulowetsedwa kwina kwa mafuta, monga zonyansa zimachepa kukula pamene zimadutsa pamtunda wokhudzana ndi zonyamula panthawi yogwira ntchito.Chinyezi ndi chinyezi ndizofunikira kwambiri pakubala kuwonongeka.Mafuta angapereke chitetezo ku kuwonongeka koteroko.Mafuta ena, monga calcium complex ndi aluminiyamu complex greases, amakhala ndi madzi ochuluka kwambiri.Mafuta opangidwa ndi sodium ndi osungunuka m'madzi motero sangathe kugwiritsidwa ntchito popanga madzi.Kaya ndi madzi osungunuka kapena madzi oyimitsidwa m'mafuta opaka mafuta, akhoza kukhala ndi zotsatira zoopsa pa moyo wotopa.Madzi amatha kuwononga mayendedwe, ndipo dzimbiri zimachepetsa kutopa.Njira yeniyeni yomwe madzi angachepetsere kutopa kwamoyo sikudziwika bwino.Koma akuti madzi amatha kulowa ma microcracks mumayendedwe othamanga, omwe amayamba chifukwa cha kupsinjika kobwerezabwereza.Izi zitha kuchititsa dzimbiri ndi hydrogen embrittlement ya microcracks, kuchepetsa kwambiri nthawi yofunikira kuti ming'aluyi ikule mpaka kukula kosavomerezeka.Madzi amadzimadzi monga madzi a glycol ndi ma emulsions otembenuzidwa awonetsanso kuchepetsa kukhala ndi moyo wotopa.Ngakhale kuti madzi omwe amachokerako sali ofanana ndi madzi oipitsidwa, zotsatira zake zimagwirizana ndi mfundo za m'mbuyomu zoti madzi amawononga mafuta.Mapeto onse a manja okwera ayenera kukhala ofukula, mkati ndi kunja kwake ayenera kutsukidwa bwino, ndipo manjawo ayenera kukhala aatali kuti atsimikizire kuti mapeto a mkonowo akadali aatali kuposa mapeto a shaft atayikidwa.Mbali yakunja ya nyumbayo iyenera kukhala yaying'ono pang'ono kuposa m'mimba mwake.Kubowola kwake sikucheperachepera kukula kwa phewa lanyumba lomwe likulimbikitsidwa mu Timken® Spherical Roller Bearing Selection Guide (Order No. 10446C) pa timken.com/catalogs Mphamvu yofunikira ndikuyika mosamalitsa zonyamula pa shaft ndikuwonetsetsa kuti zili bwino. perpendicular to the centerline of the shaft.Ikani kukanikiza kokhazikika ndi chotengera chamanja kuti mugwire mwamphamvu tsinde kapena phewa la nyumba.
