经常对泰州SKF轴承61812-2Z显微清洁维护所避免的问题
价格:99.00
进口泰州SKF轴承安装后,应进行一定的清洗和***。所谓清洁度试验是从滚动轴承中分离杂质并测量其污染的试验方法。目前,清洁度检测方法主要有三种:质量检验、显微计数试验和自动颗粒计数试验。AfterinstallationofimportedSKFbearingsinTaizhou,certaincleaningandmaintenanceshouldbecarriedout.Theso-calledcleanlinesstestisatestmethodforseparatingimpuritiesfromrollingbearingsandmeasuringtheircontamination.Atpresent,therearethreekindsofcleanlinessdetectionmethods:qualityinspection,microscopiccountingtestandautomaticparticlecountingtest.1。自动颗粒计数试验。1.Automaticparticlecountingtest.基于光电理论和质量法的自动颗粒计算方法不同于颗粒计算方法。该方法具有较高的准确度,可直接测定杂质粒子的数量和大小。它通常适用于要求高清洁度的滚动轴承。Theautomaticparticlecalculationmethodbasedonphotoelectrictheoryandmassmethodisdifferentfromtheparticlecalculationmethod.Themethodhashighaccuracyandcandirectlydeterminethenumberandsizeofimpurityparticles.Itisusuallysuitableforrollingbearingsrequiringhighcleanliness.2。显微镜检查。2.Microscopicexamination.这种方法与质量方法相似。用显微镜直接观察滤膜中杂质颗粒的大小和数量。不同之处在于,清洗液的化学成分和杂质含量可以在过滤后测定。该方法**适用于轴承精*密泰州SKF轴承的清洁度测量。它也可以基于杂质的形状。Thismethodissimilartothequalitymethod.Thesizeandquantityofimpurityparticlesinthefiltermembranewereobserveddirectlywithamicroscope.Thedifferenceisthatthechemicalcompositionandimpuritycontentofthecleaningsolutioncanbedeterminedafterfiltration.Thismethod**issuitableformeasuringthecleanlinessofSKFbearingsinMitai.Itcanalsobebasedontheshapeofimpurities.三。质量方法试验。Three.Qualitymethodtest.进口轴承按J*B/T50-2005相关***标准进行过滤、干燥、称重。首先,将滚动轴承中的杂质清洗到清洗液中,计算杂质的质量。Theimportedbearingsarefiltered,driedandweighedaccordingtotherelevantnationalstanda***ofJ*B/T50-2005.Firstly,impuritiesinrollingbearingsarecleanedintothecleaningsolutiontocalculatethequalityofimpurities.轴承烧*伤的塑性变形PlasticDeformationofBearingBurns在过大的静载荷和冲击载荷作用下,环形工件的滚子或滚道上出现不均匀的塑性变形坑。这经常发生在非常低的速度或摆动轴承。Underexcessivestaticandimpactloads,unevenplasticdeformationpitsappearontherollersorracewaysofannularworkpieces.Thisoftenhappensatverylowspeedsorswingbearings.泰州SKF轴承烧*伤的主要原因是滚动轴承的润滑不*良,这可能是由于使用不规则的润滑剂,或润滑剂过多或不足,这是不正确的。所谓轴承烧坏状态是指:滚道轮、滚动体及轴承保持架在旋转过程中急剧加热直至变色、软*化、沉积和损坏。TaizhouSKFbearingburnsaremainlyduetopoorlubricationofrollingbearings,whichmaybeduetotheuseofirregularlubricants,orexcessiveorinsufficientlubricants,whichisincorrect.Theso-calledbearingburnoutstaterefersto:racewaywheel,rollingelementandbearingcageareheatedsharplyintheprocessofrotationuntildiscoloration,softening,depositionanddamage.也可能有太多的负载(过多的预载)。速度太高了。水或其*他******。间隙太小了。如果上述两个条件都好,轴承箱的精度,即轴和轴的挠度。Theremayalsobetoomuchload(toomuchpreloading).Thespeedistoohigh.Waterorotherforeignbodiesinvade.Theclearanceistoo***all.Iftheabovetwoconditi***aregood,theaccuracyofthebearingbox,thatis,thedeflectionoftheshaftandshaft.研究要协调,轴承间隙和预紧,密封装置要改进。检查轴和轴承箱的精度。听着,我想每个人都想知道答案。首先,选择合适的滚动泰州SKF轴承润滑剂及其用量,研究润滑剂和润滑方法,选择合适的轴承。Researchshouldbecoordinated,bearingclearanceandpre-tightening,sealingdeviceshouldbeimproved.Checktheaccuracyofshaftandbearingbox.Listen,Ithinkeveryonewantstoknowtheanswer.Firstly,choosetheappropriatelubricantanditsdosageforrollingTaizhouSKFbearing,studythelubricantandlubricationmethod,andselecttheappropriatebearing.通常,深沟球轴承的温度随着轴承工作的开始而缓慢上升,并在1-2小时后达到稳定状态。轴承的正常温度随热容、散热、速度和机械负荷而变化。如果润滑和安装部件合适,轴承温度将急剧上升,进口轴承将产生异常高温。此时,我们必*须停止工作,采取必要的预防措施。Usually,thetemperatureofdeepgrooveballbearingsincreasesslowlywiththestartoftheoperationofthebearings,andreachesastablestateafter1-2hours.Thenormaltemperatureofbearingsvarieswithheatcapacity,heatdissipation,speedandmechanicalload.Ifthelubricationandinstallationpartsaresuitable,thebearingtemperaturewillrisesharply,andtheimportedbearingwillproduceabnormalhightemperature.Atthistime,wemuststopworkingandtakenecessaryprecauti***.文章来自:泰州SKF轴承www.wh-文章来自:泰州INA轴承a-文章来自:泰州NSK轴承***:524085168电话:0510-81207777手机:13311666672/13395185757)
