南京INA轴承润滑方法常用润滑脂润滑效益！NanjingINAbearinglubricationmethodscommonlyusedgreaselubricationbenefits!与润滑油相比，南京INA轴承润滑脂具有附着力好、无损耗、不滴水、耐压、密封防尘、耐腐蚀等优点。由于润滑脂不易泄漏，润滑脂几乎是持续性润滑，特别是对于立式或斜式机床，采用润滑脂润滑实现连续润滑效果。然而，其主要缺点是，与油润滑耐磨性相比，功率损失较大。并且不能起到良好的摩擦散热效果。影响南京INA轴承选择的主要因素有三个。Comparedwithlubricatingoil,NanjingINAbearinggreasehastheadvantagesofgoodadhesion,non-loss,non-dripping,pressureresistance,sealinganddust-proof,corrosionresistanceandsoon.Becausegreaseisnoteasytoleak,greaseisalmostcontinuouslubrication,especiallyforverticalorinclinedmachinetools,usinggreaselubricationtoachievecontinuouslubricationeffect.However,themaindrawbackisthatcomparedwiththeoillubricatedwearresistance,thepowerlossislarge.Andcannotplayagoodfrictionheatdissipationeffect.TherearethreemainfactorsthataffecttheINAbearingselectioninNanjing.1，工作速度1,workingspeed工作速度是选择润滑脂的重要因素。公式dnd（mm）可以用来表示轴承内圈的直径，N（r/min）可以用来表示速度。对于轴承，润滑脂的DN值约为0.3×106。Workingspeedisanimportantfactorinchoosinggrease.Theformuladnd(mm)canbeusedtorepresentthediameterofthebearinginnerring,andN(r/min)canbeusedtoexpressspeed.Forbearings,theDNvalueofgreaseisabout0.3*106.2，工作负荷2,workload当南京INA轴承承受重负荷时，应选择高粘度润滑脂和低渗透性润滑脂，以在接触表面之间形成良好的润滑膜。随着轴承载荷的减小，润滑脂的粘度降低。WhenNanjingINAbearingsbearhe***yloads,highviscositygreaseandlowpermeabilitygreaseshouldbeselectedtoformagoodlubricationfilmbetweenthecontactsurfaces.Asthebearingloaddecreases,theviscosityofthegreasedecreases.3，工作温度3,workingtemperature润滑脂的选择受温度的影响，温度的变化会引起轴承粘度的变化，从而影响其润滑性能。南京INA轴承润滑脂的粘度不应低于20mm2/S，在选择润滑脂时，应注意润滑脂的滴点、渗透性和低温性能。Theselectionofgreaseisaffectedbytemperature,andthechangeoftemperaturewillcausethechangeofbearingviscosity,thusaffectingitslubricationperformance.TheviscosityofNanjingINAbearinggreaseshouldnotbelowerthan20mm2/S.Whenselectinggrease,thedroppingpoint,permeabilityandlowtemperatureperformanceofgreaseshouldbepaidattentionto.这些都是影响油脂选择的主要因素，但在实践中，很多因素，而且通过选择不同的润滑脂性质，如润湿条件或各种润湿条件，不溶性油应是优先选择，水溶性油应该是。Thesearethemainfactorsaffectingthechoiceofgrease,butinpractice,manyfactors,andbychoosingdifferentgreaseproperties,suchaswettingconditi***orvariouswettingconditi***,insolubleoilshouldbethepriority,water-solubleoilshouldbe.文章来自：南京SKF轴承www.wh-文章来自：南京INA轴承a-文章来自：南京NSK轴承***：524085168电话：0510-81207777手机：13311666672)
