提高江苏SKF轴承主轴的速度是实现高速、实用主轴的关键。随着高速的发展，***的机床正在研制中。轧制材料由陶瓷材料制成。DMN值约为20×104。数控加工中心的DMN值在润滑脂下为100×104，数控加工中心不断增加。它已成为一种发展趋势。油气润滑和油雾润滑也将成为未来高速机床主轴江苏SKF轴承润滑的发展方向。ImprovingthespeedofSKFbearingspindleinJiangsuisthekeytoachievehighspeedandpracticalspindle.Withthedevelopmentofhighspeed,efficientmachinetoolsarebeingdeveloped.Therollingmaterialismadeofceramicmaterial.TheDMNvalueisabout20*104.TheDMNvalueofCNCmachiningcenteris100x104undergrease,andCNCmachiningcenterisincreasing.Ithasbecomeatrendofdevelopment.OilandgaslubricationandoilmistlubricationwillalsobecomethefuturedevelopmentdirectionofJiangsuSKFbearinglubricationforhighspeedmachinetoolspindle.1，高速主轴轴承的研制1,developmentofhighspeedspindlebearing一般来说，高刚性和高速性能的角接触球江苏SKF轴承通常用于满足机床主轴的高速要求。第二，使用圆柱滚子轴承。Generallyspeaking,highrigidityandhigh-speedperformanceofangularcontactballJiangsuSKFbearingsareusuallyusedtomeetthehigh-speedrequirementsofmachinetoolspindle.Second,cylindricalrollerbearingsareused.在润滑脂条件下，DMN值小于50×104。随着油气润滑的发展，相应的润滑系统也逐渐发展起来。主轴江苏SKF轴承DMM的高速性能（DM为轴承圆直径mm×n为速度r/min），DMN值达到100×104。Undertheconditionofgrease,theDMNvalueislessthan50*104.Withthedevelopmentofoilandgaslubrication,thecorrespondinglubricationsystemhasgraduallydeveloped.HighspeedperformanceofspindleJiangsuSKFbearingDMM(DMismmdiameterndiameterofbearingcirclediameterisr/min),DMNvaluereaches100*104.滚动江苏SKF轴承的角接触球轴承也是在轴承中发展起来的。DMN值为200×104×104×90s，射流润滑的DMN值可达到300×104。TheangularcontactballbearingsforrollingJiangsuSKFbearingsarealsodevelopedinbearings.TheDMNvalueis200x104x104x90s,andtheDMNvalueofjetlubricationcanreach300*104.2，高速主轴轴承技术2,highspeedspindlebearingtechnology高速角接触球江苏SKF轴承可以看出圆锥滚子轴承、单列和双列圆柱滚子轴承在高速性能方面不如角接触球轴承。角接触轴承是一种具有接触角的轴承。HighspeedangularcontactballbearingsofJiangsuSKFcanbeseenthattaperedrollerbearings,singlerowanddoublerowcylindricalrollerbearingsarenotasgoodasangularcontactballbearingsintermsofhighspeedperformance.Angularcontactbearingisakindofbearingwithcontactangle.接触角越大，江苏SKF轴承轴向刚度越好，但陀螺仪和滚道之间的旋转滑移越大，热量越大。为了提高速度性能，该方法是减小球的尺寸（或质量），改变通道的曲率系数，以减小球的离心力，以减少高速产生的内部载荷，并增加球的数量来改善球。他很固执。Thegreaterthecontactangle,thebetteraxialstiffnessofSKFbearinginJiangsu,butthegreatertherotationslipbetweengyroscopeandraceway,thegreatertheheat.Inordertoimprovethespeedperformance,themethodistoreducethesize(ormass)oftheball,tochangethecurvaturecoefficientofthechannel,toreducethecentrifugalforceoftheball,toreducetheinternalloadproducedathighspeed,andtoincreasethenumberofballstoimprovetheball.Heisverystubborn.3，高速主轴轴承润滑3,highspeedspindlebearinglubrication高速主轴江苏SKF轴承的发展趋势对润滑提出了更高的要求。传统的润滑脂在50×104以下的DMN值因其简单、经济的用途而被广泛应用。无需特殊维护，无需随访。它们大多是终身润滑。ThedevelopmenttrendofhighspeedspindleSKFbearingsinJiangsuhasputforwardhigherrequirementsforlubrication.ThetraditionalDMNvalueofgreaseunder50*104iswidelyusedforitssimpleandeconomicaluses.Thereisnoneedforspecialmaintenanceandnoneedforfollow-up.Mostofthemarelife-longlubrication.随着江苏SKF轴承转速的增加，当DMN值超过100×104时，采用油气润滑和油雾润滑。与润滑脂相比，温度升高不大，且能高速旋转，成为主要润滑模式。虽然喷射润滑的DMN值可以达到250×104，但需要大量的润滑油。由于搅拌阻力大，功率损失大，需要复杂的辅助设备，价格昂贵，一般不使用。WiththeincreaseofrotationalspeedofSKFbearinginJiangsu,whenDMNvalueexceeds100*104,oilairlubricationandoilmistlubricationareadopted.Comparedwithgrease,thetemperatureincreaseslittle,anditcanrotateathighspeed,becomingthemainlubricationmode.AlthoughtheDMNvalueofjetlubricationcanreach250x104,alargeamountoflubricatingoilisneeded.Becauseofthelargestirringresistanceandhighpowerloss,complexauxiliaryequipmentisneeded,whichisexpensiveandgenerallynotused.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)
