Thermal kugadzikana, oxidation kuramba uye tembiricha yakanyanyisa zvinofanirwa kutariswa pakusarudza girisi kune yakanyanya kupisa tembiricha.Mune zvisizvo zvisingagadziriswi, uko kutonhora kwekushanda kunopfuura 121 ° C, zvakakosha kusarudza yakanatswa mineral oil kana yakagadzika synthetic mafuta semafuta ekutanga.Tafura 28. Girisi tembiricha siyana Zvinosvibisa Abrasive particles Kana rolling kutakura mhando dzinoshandiswa munzvimbo yakachena, iyo huru sosi yekutakura kukuvara kuneta kweiyo rolling yekubata kumeso.Nekudaro, kana kusvibiswa kwechikamu kuchipinda muhurongwa hwekubereka, kunogona kukonzera kukuvadzwa senge galling, chiitiko chinopfupisa kubereka hupenyu.Kupfeka kunogona kuve honzeri huru yekutakura kukuvara kana zvinosvibisa zvakatipoteredza kana simbi burrs pane zvimwe zvikamu mukushandisa zvinosvibisa lubricant.Kana, nekuda kwekusvibiswa kwechikamu chemafuta, kupfeka kwekutakura kunove kwakakosha, hukuru hwakakomba hunogona kuchinja, izvo zvinogona kukanganisa kushanda kwemuchina.

Mabhengi anoshanda mumafuta ane utachiona ane mwero wekutanga wekupfeka wakakwira kupfuura mafuta asina kusvibiswa.Nekudaro, chiyero ichi chekupfeka chinodzikira nekukurumidza kana pasina kumwe kupindira kwemafuta ekuzora, sezvo zvinosvibisa zvinodzikira muhukuru sezvavanopfuura nepakati peiyo inotakura kubata kumeso panguva yekushanda kwakajairika.Unyoro uye hunyoro zvinhu zvakakosha mukutakura kukuvara.Girisi inogona kupa dziviriro pakukuvadzwa kwakadaro.Mamwe magirisi, akadai senge calcium yakaoma uye aluminium yakaoma magirosi, ane yakanyanya kupikisa mvura.Sodium based greases anonyungudika mumvura saka haagone kushandiswa mumaapplication ane mvura.Kunyangwe iri mvura yakanyungudutswa kana mvura yakaturikwa mumafuta ekuzora, inogona kuve nemhedzisiro inouraya pakutakura hupenyu hwekuneta.Mvura inogona kukanganisa mabearings, uye ngura inogona kuderedza kutakura kuneta hupenyu.Iyo chaiyo nzira iyo mvura inogona kuderedza kuneta hupenyu hainzwisiswi zvizere.Asi zvave zvichinzi mvura inogona kupinda microcracks mukutakura mijaho, iyo inokonzerwa nekudzokororwa cyclic kusagadzikana.Izvi zvinogona kutungamirira mukuora uye hydrogen embrittlement ye microcracks, zvichideredza zvakanyanya nguva inodiwa kuti mitswe iyi ikure kusvika kusingagamuchirwi hukuru hwekutsemuka.Mvura-yakadzika mvura yakadai semvura glycol uye emulsions yakashandurwa yakaratidzawo kuderedzwa kwekutakura hupenyu hwekuneta.Kunyange zvazvo mvura yainotorwa isina kufanana nemvura ine tsvina, mibairo yacho inotsigira nharo dzakapfuura dzokuti mvura inosvibisa mafuta.Migumo yose yesleeve inosungirirwa inofanira kuva yakatwasuka, mukati nekunze kwekunze kunofanira kunyatsocheneswa, uye sleeve inofanira kuva yakareba zvakakwana kuti ione kuti kuguma kwechifukidzo kuchiri kureba kupfuura kuguma kwe shaft mushure mokunge fanidzo yaiswa.Iyo dhayamita yekunze inofanira kunge idiki zvishoma pane yemukati dhayamita yeimba.Bore dhayamita isiri diki pane dhayamita yebendekete remba rinokurudzirwa muTimken® Spherical Roller Bearing Selection Guide (Order No. 10446C) at timken.com/catalogs Simba rinodiwa ndere kunyatsoisa bearing pashaft uye kuona kuti iri perpendicular to the centerline of the shaft.Isa dzvinyiriro yakatsiga neruvoko kuti ubatisise bere pashaft kana bendekete remba.
