南京INA轴承失效的主要原因是两个主要因素：缺点和过载。当外部载荷超过材料强度极限时，零件开裂称为过载开裂。超载的主要原因是主机的突然损坏或安装不当。轴承部件的微裂纹、缩孔、气泡、***、过热结构、局部烧灼等缺点也会在冲击、过载或剧烈振动下产生裂纹，称为缺点裂纹。Themainreas***forthefailureofINAbearingsinNanjingaretwomainfactors:disadvantagesandoverload.Whentheexternalloadexceedsthematerialstrengthlimit,thepartcrackingiscalledoverloadcracking.Themainreasonforoverloadisthesuddendamageorimproperinstallationofthemainengine.Bearingcomponentsofmicro-cracks,shrinkageholes,bubbles,foreignbodies,superheatedstructure,localcauterizationandothershortcomingswillalsoproducecracksunderimpact,overloadorviolentvibration,calleddefectivecracks.应当指出，上述缺点可以通过仪器手段进行正确分析，包括南京INA轴承原材料的重新检验、铸件的质量控制、轴承制造过程中的热处理和加工控制。今后仍有必要加强控制。一般来说，轴承故障大多是过载故障。Itshouldbepointedoutthattheaboveshortcomingscanbecorrectlyanalyzedbyinstrumentalmeans,includingthere-inspectionofrawmaterialsforNanjingINAbearings,thequalitycontrolofcastings,theheattreatmentandprocessingcontrolinthemanufacturingprocessofbearings.Itisstillnecessarytostrengthencontrolinthefuture.Generallyspeaking,bearingfailuresaremostlyoverloadfaults.在运行中，由于南京INA轴承外部或内部因素的影响，原有的配合间隙发生了变化，精度下降，甚至“咬死”间隙的变化也变得无效。过干涉、安装不当、温升引起的大膨胀、瞬态过载、残余奥氏体和不稳定状态下的残余应力是导致空洞转变失效的主要原因。Inoperation,duetotheinfluenceofexternalorinternalfactorsofNanjingINAbearing,theoriginalfitclearancehaschanged,theaccuracyhasdecreased,andeventhechangeof"bitedead"clearancehasbecomeinvalid.Over-interference,improperinstallation,largeexpansioncausedbytemperaturerise,transientoverload,retainedausteniteandresidualstressinunstablestatearethemaincausesofvoidtransformationfailure.如果达到良好的平滑性，杂质和湿气的正确阻塞表明不应该戴油封。然而，尽量在南京INA轴承箱打开时观察轴承并定期检查油封。检查轴承附近的油封，确保它们足以防止热或腐蚀性液体或气体沿轴穿透轴承、油或气体。如果密封件磨损，应尽快更换。Ifagood***oothnessisachieved,thecorrectobstructionofimpuritiesandmoistureindicatesthatoilsealsshouldnotbeworn.However,observebearingsasfaraspossiblewhentheINAbearingboxopensinNanjing,andchecktheoilsealsregularly.Checktheoilsealsnearthebearingstoensurethattheyaresufficienttopreventhotorcorrosiveliquidsorgasesfrompenetratingthebearings,oilorgasesalongtheshaft.Ifthesealisworn,itshouldbereplacedassoonaspossible.高温常表明南京INA轴承处于异常状态。高温对轴承润滑剂也是***的。有时轴承的过热可以归因于轴承的平滑剂。如果轴承运行超过125摄氏度，轴承寿命将减少。HightemperatureoftenindicatesthattheINAbearingofNanjingisinanabnormalstate.Hightemperatureisalsoharmfultobearinglubricants.Sometimestheoverheatofthebearingcanbeattributedtothe***oothingagentofthebearing.Ifthebearingrunsmorethan125degreesCelsius,thebearinglifewillbereduced.高温轴承失效的原因包括：润滑不适或过热平滑、载荷平滑剂、过载、轴承损坏、间隙不足、高温油封冲突等。Failurecausesofhightemperaturebearingsinclude:lubricationdiscomfortoroverheating***oothing,load***oothingagent,overload,bearingdamage,insufficientclearance,hightemperatureoilsealconflict,etc.文章来自：南京SKF轴承www.wh-Thearticleisfrom:NanjingSKFbearingwww.wh-文章来自：南京INA轴承a-Thearticleisfrom:NanjingINAbearinga-文章来自：南京NSK轴承Thearticleisfrom:NanjingNSKbearing***：524085168电话：0510-81207777手机：13311666672)
