外滚道粗加工应注意残余磨损。粗磨滚道的椭圆度、圆度、滚道位置、滚道侧面和槽精度应保证满足工艺要求，不应忽视。如果粗磨滚道的精度较差，为了使精磨滚道的精度满足工艺要求，需要手工增加粗磨余量。随着加工余量的增加，精磨进给量和切削量增加，影响机床的长期精度，导致精磨精度下降。实验表明，清洁SKF轴承当中型深沟球轴承的椭圆度、边缘圆度、滚道位置、滚道侧面和滚道槽精度满足工艺要求时，滚道精磨的粗加工余量应在0.10-0.15mm左右。外滚道粗加工不允许有烧殇。Residualwearshouldbepaidattentiontoinroughmachiningofouterraceway.Theellipticity,roundness,racewayposition,racewaysideandgrooveaccuracyofroughgrindingracewayshouldbeguaranteedtomeetthetechnologicalrequirementsandshouldnotbeneglected.Iftheprecisionofroughgrindingracewayispoor,inordertomaketheprecisionoffinegrindingracewaymeetthetechnologicalrequirements,itisnecessarytoincreasetheroughgrindingallowancemanually.Withtheincreaseofmachiningallowance,thefeedandcuttingamountoffinegrindingincrease,whichaffectsthelong-termaccuracyofmachinetoolsandleadstothedeclineofprecisiongrinding.Experimentsshowthatwhentheellipticity,edgeroundness,racewayposition,racewaysideandracewaygrooveaccuracyofmedium-sizeddeepgrooveballbearingsincleanSKFbearingsmeetthetechnologicalrequirements,theroughingallowanceofracewayfinishinggrindingshouldbeabout0.10-0.15mm.Burningisnotallowedinroughprocessingofouterraceway.清洁度试验是一种从滚动轴承中分离杂质并测量其污染的试验方法。目前，清洁度试验方法有三种：质量试验、显微计数试验和自动颗粒计数试验。Cleannesstestisatestmethodforseparatingimpuritiesfromrollingbearingsandmeasuringtheircontamination.Atpresent,therearethreekindsofcleanlinesstestmethods:qualitytest,microscopiccountingtestandautomaticparticlecountingtest.1。自动颗粒计数试验。1.Automaticparticlecountingtest.基于清洁SKF轴承光电理论的自动颗粒计算方法和质量计算方法不同于微观计算方法。该方法准确度高，可直接测定杂质粒子的数量和大小。一般适用于要求高清洁度的滚动轴承。TheautomaticparticlecalculationmethodandthequalitycalculationmethodbasedonthephotoelectrictheoryofcleanSKFbearingsaredifferentfromthemicroscopiccalculationmethod.Themethodhashighaccuracyandcandirectlydeterminethenumberandsizeofimpurityparticles.Itisgenerallyapplicabletorollingbearingsrequiringhighcleanliness.2。显微试验。2.Microscopictest.该方法的Di一步类似于质量法。用显微镜直接观察滤膜中杂质颗粒的大小和数量。区别在于，清洗液的化学成分和杂质含量可以在过滤后测定。清洁SKF轴承该方法***适用于精米轴承清洁度的测量。它也可以基于杂质的形状。TheDistepofthismethodissimilartothemassmethod.Thesizeandquantityofimpurityparticlesinthefiltermembranewereobserveddirectlywithamicroscope.Thedifferenceisthatthechemicalcompositionandimpuritycontentofthecleaningsolutioncanbedeterminedafterfiltration.Thismethod***issuitableformeasuringthecleanlinessofmilledricebearings.Itcanalsobebasedontheshapeofimpurities.三。质量方法试验。Three.Qualitymethodtest.进口轴承按***有关标准GB/T50-2005进行过滤、干燥、称重。首先，将滚动轴承中的杂质清洗成清洗液，计算出杂质的质量。Theimportedbearingsarefiltered,driedandweighedaccordingtotherelevantnationalstandardGB/T50-2005.Firstly,theimpuritiesinrollingbearingsarecleanedintocleaningliquid,andthequalityofimpuritiesiscalculated.在过大的静载荷和冲击载荷下，环的滚轴或滚道上会出现不均匀的塑性变形凹坑。这通常发生在转速或摆动非常低的轴承中。Underexcessivestaticandimpactloads,unevenplasticdeformationpitswillappearontherollerorracewayofthering.Thisusuallyoccursinbearingswithverylowrotationalspeedorswing.轴承烧殇的主要原因是滚动轴承润滑bu良，这可能是SKF轴承清洁由于使用不规则的润滑剂或过量或不足的润滑剂，而这些润滑剂是不正确的。所谓轴承烧损状态是指：轴承的滚道轮、滚动体和保持架在转动中急剧加热，直至变色、阮化、沉积和损坏。Themaincauseofbearingburnoutisthegoodlubricationofrollingbearings,whichmaybeduetotheuseofirregularlubricantsorexcessiveorinsufficientlubricants,whichareincorrectforSKFbearingcleaning.Theso-calledbearingburnoutstaterefersto:theracewaywheel,rollingelementandcageofthebearingareheatedsharplyinrotationuntildiscoloration,ruanization,depositionanddamage.它也可能超载。太快了。水或其余******。间隙太小。如果轴承箱的精度在这两种情况下都不差，即轴和轴的挠度。Itcanalsobeoverloaded.It'stoofast.Waterorotherforeignbodiesintrude.Thegapistoo***all.Iftheaccuracyofthebearingboxisnotbadinbothcases,thatis,thedeflectionoftheshaftandtheshaft.文章来自：SKF轴承清洁www.wh-Articlefrom:SKFBearingCleaningwww.wh-文章来自：INA轴承a-Articlesfrom:INABearinga-文章来自：NSK轴承Articlefrom:NSKBearing***：524085168电话：0510-81207777手机：13311666672/13395185757)
