淮安INA轴承选择不当主要是由于使用了无保持架的圆柱滚子轴承，而不是能够承受大直径和组合轴向载荷（当轴向载荷较大时）的推力轴承或轴承支撑结构。工作3000小时后，进口轴承滚动面无疲劳损伤，轴承仅出现划痕。用径向载荷计算轴承的疲劳寿命很长。TheimproperselectionofHuaianINAbearingsismainlyduetotheuseofcylindricalrollerbearingswithoutcages,ratherthanthrustbearingsorbearingsupportstructuresthatcanwithstandlargediameterandcombinedaxialloads(whentheaxialloadsarelarge).After3000hoursofwork,thereisnofatiguedamageontherollingsurfaceoftheimportedbearing,andonlyscratchesappearonthebearing.Thefatiguelifeofbearingcalculatedbyradialloadisverylong.据观察，轴承断裂材料***细小，无粗晶。断裂呈银***，易碎。Accordingtoobservation,thefracturematerialofbearinghasfinestructureandnocoarsegrain.Thefractureissilvergrayandfragile.通常，轴承安装空间有限。在大多数情况下，轴直径（或轴承内径）基于机械设计或其余设计限现制。因此，轴承类型和尺寸的选择取决于轴承的内径。因此，标准轴承的主要尺寸表是根据国际标准内径尺寸编制的。Usually,bearinginstallationspaceislimited.Inmostcases,theshaftdiameter(orbearinginnerdiameter)isbasedonmechanicaldesignorotherdesignlimitati***.Therefore,thechoiceofbearingtypeandsizedependsontheinnerdiameterofthebearing.Therefore,themaindimensiontablesofstandardbearingsarecompiledaccordingtotheinternationalstandardinternaldiameterdimensi***.根据轴承的分类，分析了进口淮安INA轴承可能的行业。关键问题是根据公司***的实际情况来识别关键行业。Accordingtotheclassificationofbearings,thepossibleindustriesofimportedHuaianINAbearingsareanalyzed.Thekeyproblemistoidentifykeyindustriesaccordingtotheactualsituationofthecompany'sstock.轴承安装：轴承安装币须在干燥清洁的环境中进行。安装前应仔细检查桥壳的安装面、轴肩端面、凹槽和连接面质量。BearingInstallation:BearingInstallationCoinshallbecarriedoutinadryandcleanenvironment.Beforeinstallation,thequalityofinstallationsurface,shoulderendsurface,grooveandconnectionsurfaceofaxlehousingshouldbecarefullychecked.轴承由于保证了轴承的正常转速和高精度，降低了维护成本，在高速高精度设备中的到了广泛的应用。Bearingiswidelyusedinhigh-speedandhigh-precisionequipmentbecauseitensuresthenormalspeedandhighaccuracyofthebearingandreducesthemaintenancecost.通常，轴由径向和轴向轴承支撑。一侧的轴承称为固定端淮安INA轴承。它同时承受径向和轴向载荷，充当固定轴和轴承箱之间的相对轴向位移。另一侧称为字由端。它只承受径向载荷，能相对地沿轴线移动。Usually,theshaftissupportedbyradialandaxialbearings.ThebearingononesideiscalledHuaianINAbearingonthefixedend.Itbearsbothradialandaxialloadsandactsastherelativeaxialdisplacementbetweenthefixedshaftandthebearingbox.Theothersideiscalledtheendoftheword.Itonlybearsradialloadandcanmovealongtheaxisrelatively.双向推力球轴承运行中的检查项目及损坏原因InspectionItemsandDamageReas***ofTwo-wayThrustBallBearinginOperation双向推力球轴承损坏后解体检查时，可根据轴承损坏情况判断故障及损坏原因。Whenthetwo-waythrustballbearingisdisassembledandinspectedafterbeingdamaged,thefaultandthecauseofthedamagecanbejudgedaccordingtothedamageofthebearing.1。轴承烧商1.Bearingburner烧坏的轴承在其滚道和滚子上有回火的颜色。烧殇通常是由于润滑不足、润滑油不合格或变质以及淮安INA轴承装配过紧造成的。Burnedbearingsh***etemperedcolorsontheirracewaysandrollers.Burningisusuallyduetoinsufficientlubrication,unqualifiedlubricantsordeterioration,andtootightassemblyofHuaianINAbearings.2。滚道表面金属剥落2.Metalspallingonracewaysurface轴承滚动体和内外环滚道表面承受周期性波动载荷，导致接触应力周期性变化。当应力循环次数达到一定值时，滚动表面或内外滚道会发生疲劳剥落。如果轴承的负荷过大，疲劳会增加。此外，轴承安装不当和轴弯曲也可能导致滚道剥落。淮安INA轴承滚道疲劳剥落会降低轴的运行精度，引起机构振动和噪声。Thesurfaceofbearingrollingelementandinnerandouterringracewaybearsperiodicfluctuatingload,whichresultsinperiodicchangeofcontactstress.Whenthenumberofstresscyclesreachesacertainvalue,fatiguespallingwilloccurontherollingsurfaceortheinnerandouterraceways.Iftheloadofthebearingistoolarge,fatiguewillincrease.Inaddition,improperbearinginstallationandshaftbendingmayalsoleadtoracewayspalling.FatiguespallingofHuaianINAbearingracewaywillreducetherunningaccuracyoftheshaftandcausevibrationandnoiseofthemechani***.文章来自：淮安SKF轴承www.wh-文章来自：淮安INA轴承a-文章来自：淮安NSK轴承***：524085168电话：0510-81207777手机：13311666672/13395185757)
