江苏NSK轴承的失效可分为停止失效和精度损失两种类型。停机是轴承失效的原因之一。例如，卡死、裂纹等，精度损失是由于轴承尺寸变化的原始描述精度，虽然可以改变，但它是一种异常操作，如磨损和腐蚀。FailureofNSKbearingsinJiangsucanbedividedintotwotypes:stopfailureandaccuracyloss.Theshutdownisoneofthereas***forthefailureofthebearing.Forexample,carddeath,crack,andsoon,theprecisionlossisduetotheoriginaldescriptionprecisionofthechangeofbearingsize,althoughitcanbechanged,itisakindofabnormaloperation,suchaswearandcorrosion.江苏NSK轴承的失效因素非常混乱。由于各种轴承的工作条件和布局不同，江苏NSK轴承的失效模式和描述特点不同。根据损伤机理可大致分为接触疲劳失效、冲突磨削和失效***、开裂失效、变形***、腐蚀失效和间隙变化失效等几种基本途径。ThefailurefactorsoftheNSKbearinginJiangsuareverychaotic.Duetothedifferentworkingconditi***andlayoutofvariousbearings,thefailuremodesanddescriptioncharacteristicsofNSKbearingsinJiangsuaredifferent.Accordingtothedamagemechani***,itcanberoughlydividedintoseveralbasicways,suchascontactfatiguefailure,conflictgrindingandfailurefailure,crackingfailure,deformationfailure,corrosionfailureandgapchangefailure.粘附是江苏NSK轴承失效的***常见形式。轴承部件之间的相对滑动冲突导致外部金属的连续损失，称为滑动摩擦损失。连续磨损会改变零件的尺寸和形状。江苏NSK轴承间隙增大，工件外观不好，旋转精度降低，轴承无法正常工作。滑动磨损可分为磨粒磨损、粘着磨损、腐蚀磨损和微动磨损。***常见的磨损和磨损机制是磨料磨损和粘着磨损。AdhesionisthemostcommonformofNSKbearingfailureinJiangsu.Therelativeslidingconflictbetweenthebearingcomponentsleadstothecontinuouslossoftheexternalmetal,whichiscalledslidingfrictionloss.Continuouswearwillchangethesizeandshapeofthepart.ThebearingclearanceofJiangsuNSKincreases,theappearanceoftheworkpieceisnotgood,therotationaccuracyisreduced,andthebearingcannotworknormally.Slidingwearcanbedividedintoabrasivewear,adhesivewear,corrosivewearandfrettingwear.Themostcommonwearandwearmechani***sareabrasivewearandadhesivewear.接触疲劳失效是各类江苏NSK轴承***常见的失效形式之一。反复的接触应力反复影响轴承表面的失效。轴承零件的接触疲劳是疲劳裂纹萌生和扩展的过程。初始接触疲劳裂纹首先发生在接触表面以下的***大正交剪切应力，然后延伸到江苏NSK轴承表面以形成点蚀或小的片材。前者称为点蚀或剥落，后者称为浅层。如果在与心脏相邻的硬化层中存在初始裂纹，则硬化层的早期脱落称为硬化层脱落。ContactfatiguefailureisoneofthemostcommonfailuremodesofallkindsofNSKbearingsinJiangsu.Repeatedcontactstressesrepeatedlyaffectthefailureofbearingsurfaces.Thecontactfatigueofbearingpartsistheprocessoffatiguecrackinitiationandpropagation.Theinitialcontactfatiguecrackfirstoccursatthemaximumorthogonalshearstressbelowthecontactsurface,andthenextendstothesurfaceoftheJiangsuNSKbearingtoformpittingor***allsheet.Theformerisknownaspittingorspalling,andthelatteriscalledshallow.Ifthereisaninitialcrackinthehardenedlayeradjacenttotheheart,theearlyfalloffofthehardenedlayeriscalledthehardenedlayerfallingoff.江苏NSK轴承磨损表面的外观是由磨粒磨损引起的。在轴承表面经常形成凿削或沟槽磨损。外来的硬粒子通常来自空气中的杂质。主要原因是粘着磨损主要是由于冲突外观的一般峰值，使得冲突表面的力不均匀，并且一些冲突热使表面温度升高的冲突，形成光滑的江苏NSK轴承油膜断裂，和表面金属。当E部分溶解时，接触点在严重时会引起接触点的粘附、撕裂和再粘附，失效。TheappearanceofwornsurfaceofNSKbearinginJiangsuiscausedbyabrasivewear.Chiselorgroovewearisoftenformedonthebearingsurface.Foreignhardparticlesusuallycomefromimpuritiesintheair.Themainreasonisthattheadhesivewearismainlyduetothegeneralpeakoftheconflictappearance,whichmakestheforceunevenonthesurfaceoftheconflict,andsomeconflictheatmakesthesurfacetemperaturerise,forminga***oothoilfilmfractureoftheJiangsuNSKbearing,andthesurfacemetal.WhenEispartiallydissolved,thecontactpointwillcauseadhesion,tearandreadhesionofthecontactpointwhenitisserious.文章来自：江苏SKF轴承www.wh-Thearticlecomesfrom:JiangsuSKFbearingwww.wh-文章来自：江苏INA轴承a-Thearticlecomesfrom:JiangsuINAbearinga-文章来自：江苏NSK轴承Thearticlecomesfrom:JiangsuNSKbearing)
