润滑对轴承的运行和寿命有着非常重要的影响。简要介绍了油脂的选择原则。润滑脂由基础油、增稠剂和添加剂组成。不同等级润滑脂的性能与同等级润滑脂有很大的不同。注意选择很重要。润滑脂的性能主要取决于基础油。高粘度适用于高温高负荷。浓密机的润滑性能也与之有关。增稠剂的耐水性决定了润滑脂的耐水性。Lubricationhasaveryimportantimpactontheoperationandlifeofbearings.Lubricatinggreasec***istsofbaseoil,thickenerandadditive.Theperformanceofdifferentgradegreasesisquitedifferentfromthatofthesamegradegreases.It'simportanttopayattentiontochoices.Theperformanceofgreasemainlydependsonbaseoil.Highviscosityissuitableforhightemperatureandhighload.Thelubricationperformanceofthethickenerisalsorelatedtoit.Thewaterresistanceofthethickenerdeterminesthewaterresistanceofthegrease.1。INA组合轴承设备准备1.INACompositeBearingEquipmentPreparation（1）轴承安装应清洁：安装现场应与车床、磨床等机械设备保持一定距离。现场应清洁干净，并始终坚持干燥、清洁、进水轴承。对轴承箱（座）、轴等相关部件进行反思，确保其清洁。轴承应留在原包装中，直到安装前一刻，以避免污染。(1)Bearinginstallationshouldbeclean:theinstallationsiteshouldkeepacertaindistancefromthelathe,grinderandothermechanicalequipment.Thesiteshouldbecleanandclean,andalwaysadheretodry,clean,waterinletbearing.Reflectonthebearingbox(seat),shaftandotherrelatedcomponentstoensureitscleanliness.Bearingsshouldbeleftintheoriginalpackaginguntilthemomentbeforeinstallationto***oidpollution.原则上，不同品牌的润滑脂不能混合，即使是相同的增稠剂润滑脂，由于添加剂的不同，也会对彼此产生***影响。Inprinciple,differentbrandsofgreasecannotbemixed,eventhesamethickenergrease,duetothedifferentadditives,willh***eanegativeimpactoneachother.INA组合轴承表面涂有防锈油。安装使用前，bi须用清洁的***或煤油仔细清洗，然后涂上清洁的优zhi或高速高温润滑脂。清洁度对轴承寿命、振动和噪声有很大影响。但我们要特别提醒您，全封闭轴承不需要清洗和上油。INAcompositebearingsarecoatedwithanti-rustoil.Beforeinstallationanduse,Bishouldbecarefullycleanedwithcleangasolineorkerosene,andthencoatedwithcleanYouzhiorhigh-speedandhigh-temperaturegrease.Cleanlinesshasagreatinfluenceonbearinglife,vibrationandnoise.Butwewouldliketoremindyouinparticularthatfullyenclosedbearingsdonotneedtobecleanedandoiled.此外，至少14个百分点的密封轴承被轴承污染，不需要进行润滑脂维护。这些轴承仅用于所有早期轴承故障的一小部分。轴承具有优良的制造和设计能力，能在各种恶劣的工作条件下提供密封解决方案。Inaddition,atleast14percentofthesealedbearingsarecontaminatedbythebearingsanddonotrequiregreasemaintenance.Thesebearingsareusedonlyfora***allpartofallearlybearingfailures.Bearingsh***eexcellentmanufacturinganddesigncapabilitiesandcanprovidesealingsoluti***undervariousharshworkingconditi***.安装条件是使用中***重要的因素之一。INA组合轴承安装不当往往导致整套轴承各部分应力状态的变化。轴承非正常运行和早期使用寿命的内在因素主要是结构设计、制造工艺和材料质量，决定了轴承的质量。Installationconditionisoneoftheimportantfactorsof***inuse.TheinappropriateinstallationofINAcompositebearingsoftenresultsinthechangeofstressstateofeachpartofthewholebearing.Theinternalfactorsofabnormaloperationandearlyservicelifeofbearingsaremainlystructuraldesign,manufacturingprocessandmaterialquality,whichdeterminethequalityofbearings.（1）检查轴承是否增加了意外载荷和安装误差，可作为调查轴承损坏原因的线索。(1)Checkingwhetherthebearinghasincreasedtheunexpectedloadandinstallationerrorcanbeusedasacluetoinvestigatethecauseofbearingdamage.（2）轴承的安装参数，如轴承与轴、轴承座的配合、安装时的偏差等，也会影响轴承的振动。(2)Theinstallationparametersofbearings,suchasthematchingofbearingswithshaftsandbearingseats,andthedeviationduringinstallation,willalsoaffectthevibrationofbearings.当INA组合轴承转动时，内外环的滚道表面与滚动体接触，使滚道变暗，使滚道与滚道表面的连接正常，从而了解载荷。因此，在拆卸万向节轴承时，请密切注意并观察滚道表面的轨迹。轴承箱承受较大的轴向载荷、轴承力矩载荷或不同的极限刚度。WhentheINAcombinedbearingrotates,theracewaysurfaceoftheinnerandouterringscontactswiththerollingbody,whichdarkenstheracewayandmakestheconnectionbetweentheracewayandtheracewaysurfacenormal,soastounderstandtheload.Therefore,whendisassemblinguniversaljointbearings,pleasepaycloseattentiontoandobservethetrackofracewaysurface.Bearingboxbearslargeaxialload,bearingmomentloadordifferentultimatestiffness.（3）轴承状况：在轴承运行过程中，负载、转速和润滑状况对轴承振动的影响***大。(3)Bearingcondition:Intheprocessofbearingoperation,load,speedandlubricationconditionh***egreatinfluenceonbearingvibration.（4）轴承设计参数：包括轴承滚子数量、环壁厚度和间隙。(4)Bearingdesignparameters:includingthenumberofbearingrollers,ringwallthicknessandclearance.轴承零件制造误差：包括INA组合轴承滚道和滚动表面粗糙度。大量实验研究表明，波纹磨损对轴承振动起主导作用，而表面粗糙度和圆度的影响相对较小。Manufacturingerrorofbearingparts:includingINAcombinedbearingracewayandrollingsurfaceroughness.Alargenumberofexperimentalstudiesh***eshownthatcorrugatedwearplaysadominantroleinbearingvibration,whiletheinfluenceofsurfaceroughnessandroundnessisrelatively***all.轴承是精mi零件。线性轴承和润滑脂被污染，无法工作。Thebearingisaprecisionmipart.Linearbearingsandgreasesarecontaminatedandcannotwork.（5）轴承检查应在工厂或库存后立即完成。整个检验过程的完成时间不宜过长，以免腐蚀。应注意使用清洁、无油的纯***，这也会引起腐蚀。(5)Bearinginspectionshallbecompletedimmediatelyafterthefactoryorinventory.Thecompletiontimeofthewholeinspectionprocessshouldnotbetoolongto***oidcorrosion.Attentionshouldbepaidtotheuseofclean,oil-freepuregasoline,whichcanalsocausecorrosion.文章来自：SKF轴承www.wh-Articlefrom:SKFBearingwww.wh-文章来自：INA组合轴承a-Articlesfrom:INACompositeBearinga-文章来自：NSK轴承Articlefrom:NSKBearing***：524085168***:524085168电话：0510-81207777Tel:0510-81207777手机：13311666672/13395185757Mobilephone:13311666672/13395185757)
