轴承表面热处理可分为两类：一类是表面淬火和回火热处理，采用振动吸收或隔离装置降低淮安SKF轴承噪音或隔离噪音；另一类是化学热处理。Bearingsurfaceheattreatmentcanbedividedintotwocategories:oneissurfacequenchingandtemperingheattreatment,usingvibrationabsorptionorisolationdevicetoreducethenoiseorisolationnoiseofHuaianSKFbearing;theotherischemicalheattreatment.轴承的化学热处理是将一种或几种化学元素的原子渗入工件表面，从而改变工件表面的化学成分、结构和性能。经淬火和低温回火后，工件表面.具有较高的硬度、耐磨性和接触疲劳强度，而工件的核心具有较高的韧性。Chemicalheattreatmentofbearingsistoinfiltrateatomsofoneorseveralchemicalelementsintothesurfaceofworkpieces,thuschangingthechemicalcomposition,structureandpropertiesoftheworkpiecesurface.Afterquenchingandlowtemperaturetempering,thesurfaceoftheworkpiecehashigherhardness,wearresistanceandcontactfatiguestrength,whilethecoreoftheworkpiecehashighertoughness.轴承化学热处理工件的主要技术参数是淬火深du和表面硬度。用维氏硬度计测定了硬化层深du。you效硬化深du是从工件表面到硬度50HRC点的距离。ThemaintechnicalparametersofbearingchemicalheattreatmentworkpiecearequenchingdepthDuandsurfacehardness.ThehardeningdepthDuwasmeasuredbyVickershardnesstester.YoueffecthardeningdepthDuisthedistancefromworkpiecesurfacetohardness50HRCpoint.轴承和化学热处理工件的表面硬度试验与表面淬火热处理工件相似。滚动轴承的噪声之一是轴承本身可以通过维氏硬度计、表面洛氏硬度计或洛氏硬度计进行试验，但渗氮厚度相对较薄，一般不超过0.7mm。此时，洛氏硬度计已不能再使用。Thesurfacehardnesstestofbearingandchemicalheattreatmentworkpieceissimilartothatofsurfacequenchingheattreatmentworkpiece.OneofthenoiseofrollingbearingisthatthebearingitselfcanbetestedbyVickershardnesstester,surfaceRockwellhardnesstesterorRockwellhardnesstester,butthenitridingthicknessisrelativelythin,generallynotmorethan0.7mm.Atthistime,Rockwellhardnesstestercannolongerbeused.如果淮安SKF轴承零件局部硬度要求较高，可采用感应加热进行局部淬火热处理。这些零件通常需要在图纸上标明局部淬火热处理的位置和局部硬度值。零件硬度试验应在指定区域进行。洛氏硬度计可用来测试HRC硬度值，如热处理硬化层较浅，表面洛氏硬度计可用来测试HRN硬度值。IfthelocalhardnessrequirementofHuaianSKFbearingpartsishigh,inductionheatingcanbeusedforlocalquenchingheattreatment.Thesepartsusuallyneedtoindicateonthedrawingthelocationofthelocalquenchingheattreatmentandthelocalhardnessvalue.Hardnesstestofpartsshouldbecarriedoutindesignatedarea.RockwellhardnesstestercanbeusedtotestHRChardnessvalue,suchasheattreatmenthardeninglayerisshallow,surfaceRockwellhardnesstestercanbeusedtotestHRNhardnessvalue.即使烘干机的长度变化很大，也可以通过内滚道和滚动体之间的相对运动进行补偿。无需摆动轴承座；Evenifthelengthofthedryervariesgreatly,itcanbecompensatedbytherelativemotionbetweentheinnerracewayandtherollingbody.Noneedtoswingthebearingseat;球面外圈和与其配合的滑动轴承圈使轴承具有对中能力。Thesphericalouterringandtheslidingbearingringmatchedwithitenablethebearingtoh***ealignmentability.通过直接向轴承供油和从两侧排油，可以获得适当的润滑。Appropriatelubricationcanbeobtainedbydirectlysupplyingoiltobearingsanddischargingoilfrombothsides.用螺栓将圆柱滚子淮安SKF轴承和轴承座固定在机架上，可以减小轴承系统的振动。ThevibrationofthebearingsystemcanbereducedbyfixingthecylindricalrollerHuaianSKFbearingandbearingseatontheframewithbolts.其余尺寸系列30、22和31的轴承可与自调心圆柱滚子轴承互换，无需修改轴承座。调心圆柱滚子轴承在极.端恶劣的条件下工作。Bearingsofothersizesseries30,22and31canbeinterchangedwithself-aligningcylindricalrollerbearingswithoutmodificationofthebearingseat.Theself-aligningcylindricalrollerbearingsworkunderextremeandextremeconditi***.尺寸稳定性高达200摄氏度。Dimensionalstabilityupto200degreesCelsius.它能承受来自四面八方的径向力。Itcanwithstandradialforcesfromallsides.在轴向位移较大的情况下，每排滚子上的载荷仍然是均匀的。Inthecaseoflargeaxialdisplacement,theloadoneachrowofrollersisstilluniform.附加倾覆力矩，如绳轮力矩或蒸汽接头力矩，可用螺栓将轴承座固定在机架上进行补偿。Additionaloverturningmoment,suchasropewheelmomentorsteamjointmoment,canbecompensatedbyfixingthebearingseatontheframewithbolts.螺栓确保淮安SKF轴承座不会在Di震多发地区被提升。BoltsensurethatHuaianSKFbearingswillnotbeliftedinareaspronetoDiearthquakes.文章来自：淮安SKF轴承www.wh-Articlefrom:HuaianSKFBearingwww.wh-文章来自：淮安INA轴承a-Articlefrom:HuaianINABearinga-文章来自：淮安NSK轴承Articlefrom:HuaianNSKBearing***：524085168电话：0510-81207777手机：13311666672/13395185757)
