空气中的油和氧之间的化学反应产生酸性物质。首先，它消耗SKF轴承润滑脂中的抗养化剂添加剂。但是，所产生的you机酸会在一定程度上腐蚀金属成分，***油的结构，降低其滴点，增加基础油的粘度，降低其流动性。大量实验表明，温度越高，润滑脂的寿命越明显。如果温度在90度到100度之间，每升高19度，脂质的寿命将缩短一半；如果温度在10度到150度之间，每升高15度，脂质的寿命将缩短一半。Thechemicalreactionbetweenoilandoxygenintheairproducesacidicsubstances.First,itc***umesanti-nutrientadditivesinSKFbearinggrease.However,theresultingyouorganicacidwillcorrodethemetalcompositiontoacertainextent,destroythestructureoftheoil,reduceitsdroppingpoint,increasetheviscosityofthebaseoil,andreduceitsfluidity.Alargenumberofexperimentsshowthatthehigherthetemperature,themore***iousthelifeofgrease.Ifthetemperatureisbetween90and100degrees,thelifespanoflipidswillbereducedbyhalfforevery19degreesincrease;ifthetemperatureisbetween10and150degrees,thelifespanoflipidswillbereducedbyhalfforevery15degreesincrease.SKF轴承润滑脂在使用过程中被机械剪切力和离心力分离，降低了含油量、锥入度和硬化。经过一定程度后，润滑脂会完全失效。在机械剪切作用下，油脂结构会被***（如皂纤维的分离或取向），导致油脂软花，稠度降低，油脂减少。增加的油沉淀***终会导致故障。SKFbearinggreaseisseparatedbymechanicalshearforceandcentrifugalforceduringuse,whichreducesoilcontent,taperpenetrationandhardening.Afteracertaindegree,thegreasewillcompletelyfail.Undermechanicalshearing,thestructureofoilwillbedestroyed(suchastheseparationororientationofsoapfibers),resultinginthesofteningofoil,thedecreaseofc***istencyandthedecreaseofoil.Increasedoilprecipitation***willeventuallyleadtofailure.此外，使用润滑脂的环境中的水分、灰尘和***气体也是导致润滑脂变质的重要因素。例如，可以通过在润滑脂中添加铜、铁、铅和青铜等磨损颗粒来催化润滑脂的氧化。简而言之，润滑脂失效的原因有很多。有时它可能是由一个原因引起的，但更多的时候SKF轴承润滑脂是由许多因素引起的，或者是突破的原因，然后是其余原因共同作用的结果。Inaddition,moisture,dustandharmfulgasesintheenvironmentwheregreaseisusedarealsoimportantfactorsleadingtogreasedeterioration.Forexample,theoxidationofgreasecanbecatalyzedbyaddingwearparticlessuchascopper,iron,leadandbronzeintogrease.Inshort,therearemanyreas***forgreasefailure.Sometimesitmaybecausedbyonereason,butmoreoftenSKFbearinggreaseiscausedbymanyfactors,orthecauseofbreakthrough,andthentheresultofthecombinedactionofotherreas***.游离碱是指皂基润滑脂在制造过程中不与脂肪酸相互作用的过量碱；游离you机酸是指在制造过程中不可皂化的脂肪酸，或烃基润滑脂本身含有酸（环烷酸），或润滑脂中矿物油的氧化或皂化产物。Freebasereferstoexcessivebasewhichdoesnotinteractwithfattyacidsinthemanufacturingprocessofsoap-basedgrease;freeyouorganicacidreferstounsaponifiablefattyacidsinthemanufacturingprocess,orhydrocarbongreaseitselfcontainsacid(naphthenicacid),oroxidationorsaponificationproductsofmineraloilingrease.虽然可以安装各种轴承密封，但由于润滑脂技术不正确和使用不当，轴承早期失效率仍为36个百分点。任何SKF轴承润滑脂不当的轴承在其正常使用寿命内都将不可避免地发生故障。机械和设备轴承通常是***困难的部分，没有固定的润滑将是一个问题。在没有人工维护的情况下，是不可能实现的，可以开发自动润滑系统来达到***佳的润滑效果。对润滑脂、工具和you效润滑技术的需求将大大减少停机时间。Althoughvariousbearingsealscanbeinstalled,theearlyfailurerateofbearingsisstill36percentagepointsduetoincorrectlubricatinggreasetechnologyandimproperuse.AnybearingwithimproperSKFbearinggreasewillinevitablyfailduringitsnormalservicelife.Bearingsofmachineryandequipmentareusuallythedifficultpartof***,andnofixedlubricationwillbeaproblem.Intheabsenceofmanualmaintenance,itisimpossibletoachieve,candevelopautomaticlubricationsystemtoachieve***goodlubricationeffect.Demandforgrease,toolsandyou-effectlubricationtechnologywillgreatlyreducedowntime.密封件与其相对运动部件之间没有间隙。由于密封件与接头直接接触，接触面摩擦大，发热量高，润滑不顺畅，摩擦损坏，密封效果和性能降低。因此，只能在中低速条件下使用。接触式密封通常用于毡封、杯形密封和其余结构形式，并在不同的情况下使用。SKF轴承润滑脂是支撑其本质的部件。它的重要功能是引导轴的旋转。它也可以是轴承轴的空转部分。Thereisnogapbetweenthesealanditsrelativemovingparts.Becauseofthedirectcontactbetweenthesealsandthejoints,thecontactsurfacehashighfriction,highcalorificvalue,poorlubrication,frictiondamage,andthesealingeffectandperformancearereduced.Therefore,itcanonlybeusedinlowandmediumspeedconditi***.Contactsealsareusuallyusedforfeltseals,cupsealsandotherstructuralforms,andareusedindifferentsituati***.SKFbearinggreaseistheessentialparttosupportit.Itsimportantfunctionistoguidetherotationoftheaxis.Itcanalsobetheidlepartofthebearingshaft.文章来自：SKF轴承润滑脂www.wh-Articlefrom:SKFbearinggreasewww.wh-文章来自：INA轴承a-Articlesfrom:INABearinga-文章来自：NSK轴承Articlefrom:NSKBearing***：524085168***:524085168电话：0510-81207777Tel:0510-81207777手机：13311666672/13395185757Mobilephone:13311666672/13395185757)
