轴承钢采用连铸机锻造时，二次散热区域分布在扇形截面上，故又称扇形截面轴承。这种轴承经常用于钢厂和其余工业，如果经常发生故障，整个南京INA轴承钢加工系统可能会瘫痪。因此，为了降低扇形轴承的维护成本，提高整个生产线的加工效率，有必要对失效原因进行分析。Whenbearingsteelisforgedbycontinuouscastingmachine,thesecondaryheatdissipationareaisdistributedonthesectorsection,soitisalsocalledsectorsectionbearing.Suchbearingsareoftenusedinsteelmillsandotherindustries,andiffrequentfailuresoccur,theentireNanjingINAbearingsteelprocessingsystemmaybeparalyzed.Therefore,inordertoreducethemaintenancecostofsectorbearingandimprovetheprocessingefficiencyofthewholeproductionline,itisnecessarytoanalyzethefailurereas***.（一）负荷分布的不均匀性(1)theinhomogeneityofloaddistribution（1）装南京INA轴承配不当造成的载荷分布不均匀。主要原因是前轴承、轴和滚子的匹配没有获得准确的测量。解决这一问题的更好的方法是调整零件之间的配合指。(1)unevenloaddistributioncausedbyimproperbearingofINAbearinginNanjing.Themainreasonisthatthematchingoffrontbearing,shaftandrollerhasnotbeenaccuratelymeasured.Abetterwaytosolvethisproblemistoadjustthematingfingersbetweenparts.（2）径向间隙不均匀引起的负荷不均匀。当轴承安装在同一滚子上时，如果间隙值过大，就会产生不均匀的轴承力，从而对南京INA轴承造成损坏。解决办法是适当调整轴承安装在同一滚子上的间隙。(2)unevenloadcausedbyunevenradialgap.Whenthebearingisinstalledonthesameroller,iftheclearancevalueistoolarge,itwillproduceunevenbearingforce,thuscausingdamagetoNanjingINAbearing.Thesolutionistoproperlyadjusttheclearancebetweenbearingsmountedonthesameroller.（二）污染物***(two)pollutantintrusion外来污染物的***主要有两个原因。首先，轴承本身是密封的，使轴承容易受到杂质的直接***，或者由于杂质在密封装置周围积聚，杂质容易进入轴承内部扇形轴承，南京INA轴承停止，I.T固定。由于轴承清洗工作没有到位或在维护环境和工作工具上都不干净，使污染物进入轴承，导致轴承寿命缩短。Therearetwomainreas***fortheinvasionofforeignpollutants.Firstofall,thebearingitselfissealed,sothatthebearingisvulnerabletodirectinvasionofimpurities,orbecauseimpuritiesaccumulatedaroundthesealingdevice,impuritieseasytoenterthebearinginternalsectorbearing,NanjingINAbearingstopped,I.Tfixed.Becausethebearingcleaningworkisnotinplaceorinthemaintenanceoftheenvironmentandworkingtoolsarenotclean,sothatpollutantsintothebearing,resultinginshortenedbearinglife.为了解决这个问题，我们需要做的就是改进轴承密封装置，它不仅可以防止漏油，而且可以防止污染物的***。同时，风机轴承须清洗和***。Tosolvethisproblem,weneedtodoistoimprovethebearingsealingdevice,itcannotonlypreventoilleakage,butalsopreventtheinvasionofpollutants.Meanwhile,fanbearingsmustbecleanedandmaintained.（三）径向间隙尺寸的影响。(three)theinfluenceofradialclearancesize.间隙的大小不仅影响南京INA轴承的载荷分布不均匀，而且会引起轴承噪声、温升、旋转精度下降等故障。因此，有必要合理选择扇形轴承的径向游隙。ThesizeofclearancenotonlyaffectstheunevenloaddistributionofNanjingINAbearings,butalsocausesbearingnoise,temperaturerise,rotationaccuracydeclineandotherfaults.Therefore,itisnecessarytochoosetheradialclearanceofsectorbearingsreasonably.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)
