NSK轴承故障在使用过程中具有很强的规律性和重复性。普通you质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，例如表面毛边。NSKbearingfaulthasstrongregularityandrepeatabilityintheuseprocess.Ordinaryyouthfulstainlesssteelbearingsh***elowvibrationandnoiseattheinitialstageofuse,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。超过三个频率的频率很少出现。不锈钢轴承处于非常稳定的状态，进入稳定的工作循环。连续运行后，轴承的振动和噪声开始增大，有时NSK轴承故障会出现异常声音，但振动增大到初始故障。Afteraperiodofmovement,thevibrationandnoiseremainatacertainlevel,thespectrumisverysingle,onlyoneortwotimesthefrequency.Frequenciesexceedingthreefrequenciesrarelyoccur.Stainlesssteelbearingsareinaverystablestateandenterastableworkingcycle.Aftercontinuousoperation,thevibrationandnoiseofthebearingbegintoincrease.SometimestheNSKbearingfaultwillappearabnormalsound,butthevibrationincreasestotheinitialfault.首先，轴承光谱分析发现铁浓度异常，铁谱图中存在大量铁亚微米磨损颗粒，润滑油的水酸值异常，说明轴承座磨损是由磨损引起的。Firstly,thebearingspectrumanalysisfoundthattheironconcentrationwasabnormal,therewerealargenumberofironsubmicronwearparticlesintheferrograph,andthewateracidvalueoflubricatingoilwasabnormal,whichindicatedthatthewearofbearingseatwascausedbywear.其次，轴承光谱分析发现有色金属元素浓度异常，铁谱中存在大量亚微米级磨损颗粒。润滑油的含水量和酸值过高表明轴瓦表面腐蚀。Secondly,thebearingspectrumanalysisfoundthattheconcentrationofnon-ferrousmetalelementswasabnormal,andtherewerealargenumberofsub-micronwearparticlesintheferrography.Excessivewatercontentandacidvalueoflubricatingoilindicatethatthebearingsurfaceiscorroded.第三，通过轴承谱分析发现铁浓度异常。铁谱学包含许多亚微米铁粒子。润滑油含水量或酸值过高，说明滚针NSK轴承故障轴颈表面腐蚀。Thirdly,abnormalironconcentrationwasfoundbybearingspectrumanalysis.Ferrographycontainsmanysubmicronironparticles.TheexcessivewatercontentoracidvalueoflubricatingoilindicatesthatthesurfaceofthefaultJournalofneedlerollerNSKbearingiscorroded.第四，不锈钢轴承铁谱中含有黑色切削磨料或黑色氧化物颗粒。金属表面回火颜色表明轴承轴颈表面损坏。Fourth,ferrographyofstainlesssteelbearingscontainsblackcuttingabrasivesorblackoxideparticles.Thetemperingcolorofthemetalsurfaceindicatesthatthebearingjournalsurfaceisdamaged.第五，轴承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。Fifth,cuttingabrasivesarefoundinbearingferrography,andtheabrasivecompositionisnon-ferrousmetal,indicatingthatthebearingsurfaceisdamaged.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。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NSK轴承故障静止时，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。当轴承密封bu良、灰尘或颗粒物进入轴承或润滑布良时，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。Sinceweknowthecauseofbearingfailure,weshouldpayattentiontotheseaspects.Theservicelifeofstainlesssteelbearingsincreasesnaturally.Whentheexternalhardparticlesenterthebearingandpressbetweenthebearingbodyandtheraceway,thesurfacewillproducedents.Inaddition,excessiveimpactloadwillalsoleadtolocalplasticdeformationofthecontactsurface,formingpits.WhenthefailureofNSKbearingsisstill,eveniftheloadisvery***all,thevibrationofthesurroundingenvironmentwillformauniformpitontheraceway.WhenthebearingsealBuLiang,dustorparticulatematterenterthebearingorlubricatingclothLiang,itwillcauseseriouswearorwearofthecontactsurface,andincreasethevibrationandnoiseofstainlesssteelbearings.文章来自：SKF轴承故障www.wh-Articlefrom:SKFBearingFaultwww.wh-文章来自：INA轴承故障a-Articlesfrom:INABearingFaulta-文章来自：NSK轴承故障Articlesfrom:NSKBearingFault***：524085168电话：0510-81207777手机：13311666672/13395185757)
