INA轴承故障预防在使用过程中具有很强的规律性和重复性。品质优良的不锈钢轴承在使用初期振动和噪声小，但频谱分散，振幅小。这可能是由于制造过程中的一些缺点造成的，例如表面粗糙度。INAbearingfaultpreventionhasstrongregularityandrepeatabilityintheuseprocess.Stainlesssteelbearingswithgoodqualityh***elowvibrationandnoiseattheinitialstageofservice,butthefrequencyspectrumisdispersedandtheamplitudeis***all.Thismaybeduetosomeshortcomingsinthemanufacturingprocess,suchassurfaceroughness.经过一段时间的运动，振动和噪声保持在一定的水平，频谱非常单一，只有频率的一到两倍。频率超过三个频率的情况很少发生。不锈钢轴承处于非常稳定的状态，进入稳定的工作循环。Afteraperiodofmovement,thevibrationandnoiseremainatacertainlevel,thespectrumisverysingle,onlyoneortwotimesthefrequency.Frequenciesexceedingthreefrequenciesrarelyoccur.Stainlesssteelbearingsareinaverystablestateandenterastableworkingcycle.连续运行后，轴承的振动和噪声开始增大，有时会出现异常声音，但振动增大到初始故障。Aftercontinuousoperation,thevibrationandnoiseofthebearingbegintoincrease,sometimesabnormalsoundwillappear,butthevibrationincreasestotheinitialfault.首先，轴承光谱分析发现，有色金属元素浓度异常，INA轴承故障预防铁谱中出现大量有色金属成分的亚微米磨损颗粒。润滑油的含水量和酸值过高表明轴承表面受到腐蚀。Firstofall,bearingspectrumanalysisfoundthattheconcentrationofnon-ferrousmetalelementsisabnormal,INAbearingfaultpreventionferrographyappearsalargenumberofsub-micronwearparticlesofnon-ferrousmetalcomponents.Excessivewatercontentandacidvalueoflubricatingoilindicatethatthebearingsurfaceiscorroded.其次，轴承光谱分析发现铁浓度异常，铁谱中存在亚铁亚微米磨损颗粒，润滑油的水酸值异常，说明轴承磨损是由微动引起的。Secondly,bearingspectrumanalysisfoundthatironconcentrationwasabnormal,ferroussubmicronwearparticlesexistedinferrography,andwateracidvalueoflubricatingoilwasabnormal,whichindicatedthatbearingwearwascausedbyfretting.第三，不锈钢轴承的铁谱中含有黑色切削磨粒或黑色氧化物颗粒，金属表面的回火颜色表明轴承轴颈表面损坏。Thirdly,theferrographyofstainlesssteelbearingscontainsblackcuttingabrasiveparticlesorblackoxideparticles,andthetemperingcolorofthemetalsurfaceindicatesthatthebearingjournalsurfaceisdamaged.第四，INA轴承故障预防铁谱中发现切削磨料，磨料成分为有色金属，表明轴承表面损坏。Fourthly,cuttingabrasivesarefoundinINAbearingfailurepreventionferrography.Theabrasivecompositionisnon-ferrousmetal,indicatingthatthebearingsurfaceisdamaged.第五，轴承光谱分析发现，铁的异常浓度，存在许多亚微米铁颗粒，润滑油水分或酸值超标，说明滚针轴承的轴颈表面受到腐蚀。Fifth,bearingspectrumanalysisfoundthattheabnormalconcentrationofiron,therearemanysubmicronironparticles,lubricatingoilmoistureoracidvalueexceededthestandard,indicatingthatthejournalsurfaceofneedlerollerbearingswascorroded.既然我们知道轴承失效的原因，就应该注意这些方面。不锈钢轴承的使用寿命自然增加。Sinceweknowthecauseofbearingfailure,weshouldpayattentiontotheseaspects.Theservicelifeofstainlesssteelbearingsincreasesnaturally.当外部硬颗粒进入轴承并压在轴承体和滚道之间时，表面会产生凹痕。此外，过大的冲击载荷还会导致接触面局部塑性变形，形成凹坑。当INA轴承故障预防静止时，即使负载很小，周围环境的振动也会在滚道上形成均匀的凹坑。Whentheexternalhardparticlesenterthebearingandpressbetweenthebearingbodyandtheraceway,thesurfacewillproducedents.Inaddition,excessiveimpactloadwillalsoleadtolocalplasticdeformationofthecontactsurface,formingpits.WhenINAbearingsfailtopreventstatic,eveniftheloadis***all,thevibrationofthesurroundingenvironmentwillformauniformpitontheraceway.当轴承密封bu良、灰尘或颗粒物进入轴承或润滑bu良时，会造成接触面严重磨损或磨损，增加不锈钢轴承的振动和噪音。WhenthebearingsealBuLiang,dustorparticulatematterenterthebearingorlubricationBuLiang,itwillcauseseriouswearorwearofthecontactsurface,andincreasethevibrationandnoiseofstainlesssteelbearings.在检查之前，应清洁机器表面，并拆下轴承周围的零件。油封是非常脆弱的零件，需要仔细拆卸，不要用力过大，然后仔细检查油封及其周围零件，如果有bu良症状，bi须更换，bu良的油封会导致轴承损坏，并严格关闭设备。Beforeinspection,themachinesurfaceshouldbecleanedandthepartsaroundthebearingshouldberemoved.Oilsealsareveryfragileparts,needtobecarefullyremoved,nottoohard,andthencarefullyinspecttheoilsealsandtheirsurroundingparts,iftherearegoodsymptomsofbu,Bimustbereplaced,Bugoodoilsealswillleadtobearingdamage,andstrictclosureofequipment.检查INA轴承故障预防润滑油，用手指间的少许油擦拭。如果有任何污染物，你可以感觉到它，或者在你的手背上涂一层薄薄的润滑剂，然后关灯。InspectINAbearingfailuretopreventlubricatingoil,wipewithalittleoilbetweenfingers.Ifthereisanycontaminant,youcanfeelit,orputathinlayeroflubricantonthebackofyourhand,andturnoffthelight.文章来自：SKF轴承www.wh-Articlefrom:SKFBearingwww.wh-文章来自：INA轴承故障预防a-Articlesfrom:INABearingFaultPreventiona-文章来自：NSK轴承Articlefrom:NSKBearing***：524085168电话：0510-81207777手机：13311666672/13395185757)
