江苏SKF轴承的环境气氛（腐蚀性、清洁性和润滑性）通常由轴向、径向和轴向两个轴承支承。在这一点上，侧轴承称为固定侧轴承，它承受两个径向和轴向载荷，以及固定轴与轴承箱之间的相对轴向位移。使用。Theenvironmentalatmosphere(corrosiveness,cleanlinessandlubricity)ofSKFbearingsinJiangsuisusuallysupportedbytwobearings,axial,radialandaxial.Atthispoint,thesidebearingiscalledthefixedsidebearing,whichbearstworadialandaxialloads,andtherelativeaxialdisplacementbetweenthefixedshaftandthebearingbox.Use.另一侧称为自由侧，仅承受径向载荷，而江苏SKF轴承的轴向可相对移动，以解决由于温度变化导致的膨胀部分与轴轴承之间的间隔误差。Theothersideiscalledthefreeside,onlybearingtheradialload,andtheaxialdirectionoftheJiangsuSKFbearingcanbemovedrelativelytosolvetheintervalerrorbetweentheexpansionpartandtheshaftbearingduetothetemperaturechange.对于固定侧滚动轴承，有必要选择江苏滚动轴承江苏SKF轴承在滚动运动（如圆柱滚子轴承）或装配表面上的轴承运动（如球轴承滚珠轴承）的轴向运动。在相对短的轴上，轴向支撑条件，例如向心推力球轴承，在固定方向和单向自由侧使用。Forafixedsiderollingbearing,itisnecessarytochoosetheaxialmotionoftheJiangsurollingbearingJiangsuSKFbearingontherollingmovement(suchascylindricalrollerbearings)orthebearingmotionontheassemblysurface(suchasballbearingballbearings).Onarelativelyshortaxis,axialsupportconditi***,suchascentripetalthrustballbearings,areusedinfixeddirectionandone-wayfreeside.江苏SKF轴承材料通常由碳钢和合金钢制成，锻件通常是锻件。优质中碳钢因其低成本、高综合力学性能而被广泛应用，其中45号钢应用***为广泛。JiangsuSKFbearingmaterialsareusuallymadeofcarbonsteelandalloysteel,andforgingsareusuallyforgings.Highqualitymediumcarbonsteeliswidelyusedbecauseofitslowcostandhighcomprehensivemechanicalproperties,ofwhichNo.45steelisthemostwidelyused.为了提高江苏SKF轴承的力学性能，应进行淬火、回火或正火。合金钢具有较高的力学性能，但价格昂贵，主要用于轴的特殊要求。InordertoimprovethemechanicalpropertiesofSKFbearinginJiangsu,quenching,temperingornormalizingshouldbecarriedout.Alloysteelhashighmechanicalproperties,butitisexpensive,andismainlyusedforspecialrequirementsofshaft.例如，大型电机转子江苏SKF轴承等轴工件在高温、高速、重载条件下必须具有良好的高温力学性能。通常采用40Cr、35SiMn、42SiMn等合金结构钢。Forexample,largemotorrotorJiangsuSKFbearingequiaxedworkpiecemusth***egoodhightemperaturemechanicalpropertiesunderhightemperature,highspeedandhe***yloadconditi***.40Cr,35SiMn,42SiMnandotheralloystructuralsteelsareusuallyused.值得注意的是，江苏SKF轴承钢的类型和热处理对轴的弹性模量影响不大。如果使用合金钢或热处理来增加轴的刚度，它就会失效。此外，合金钢对应力集中更敏感，应从结构上减少应力集中和表面粗糙度。ItisworthnotingthatthetypeandheattreatmentofSKFbearingsteelinJiangsuh***elittleeffectontheelasticmodulusoftheshaft.Ifthealloysteelorheattreatmentisusedtoincreasethestiffnessoftheshaft,itwillfail.Inaddition,thealloysteelismoresensitivetostressconcentration,andthestressconcentrationandsurfaceroughnessshouldbereducedfromthestructure.自二十世纪以来，8。自一千九百八十世纪起，江苏SKF轴承球墨铸铁得到了迅速发展。例如，球墨铸铁复合曲轴的优点是成本低，耐磨性好，对应力集中的敏***低，但缺点是冲击韧度低，质量不易被C控制。SincetwentiethCentury,8.Since1980thCentury,JiangsuSKFbearingnodularcastironhasbeendevelopingrapidly.Forexample,theadvantagesofthenodularcastironcompositecrankshaftarelowcost,goodwearresistanceandlowsensitivitytoforceconcentration,butthedisadvantageisthattheimpacttoughnessislowandthequalityisnoteasilycontrolledbyC.文章来自：江苏SKF轴承www.wh-Thearticlecomesfrom:JiangsuSKFbearingwww.wh-文章来自：江苏INA轴承a-Thearticlecomesfrom:JiangsuINAbearinga-文章来自：江苏NSK轴承Thearticlecomesfrom:JiangsuNSKbearing)
