球面滚子轴承用作***端轴承。位于发电机侧的南京NSK轴承位于轴承的正确距离处。这种尺寸的轴承的间隙选择需要结合传动链更充分和动态地考虑，并且与行星架轴承及其齿轮箱在齿轮箱中的安装有关。Sphericalrollerbearingsareusedaslocatingendbearings.TheNanjingNSKbearingonthegeneratorsideislocatedattherightdistancefromthebearing.Theclearanceselectionofbearingsofthissizeneedstobec***ideredmorefullyanddynamicallyinconjunctionwiththetran***issionchain,andisrelatedtotheinstallationofplanetaryframebearingsandtheirgearboxesingearboxes.这种自调心轴承有助于容纳两个轴承，主轴偏转，角度偏差和偏心。由于滚动元件是自对准的，所以滚动元件总是在适当的位置，所以负载均匀地分布在滚动元件的长度上。即使发生挠度或轴向位移，轴承仍能保持较高的承载能力。Thisselfaligningbearinghelpstoaccommodatetwobearings,spindledeflection,angulardeviationandeccentricity.Sincetherollingelementisself-aligned,therollingelementisalwaysinplace,sotheloadisevenlydistributedoverthelengthoftherollingelement.Evenifdeflectionoraxialdisplacementoccurs,thebearingcanstillmaintainahighbearingcapacity.由于良好的性能，两点南京NSK轴承环滚子轴承和球面滚子轴承被预先指定用于新的8MW模块化风力涡轮机和齿轮箱。基于空心轴设计，可以使用直径为1700至1800mm的滚子轴承和直径为1200至1300mm的球面滚子轴承。轴承。它还提供了新一代滚子轴承和球面滚子轴承。轴承的性能参数在耐久性、操作能力和动态承载能力方面都有很大的提高。性能改进归功于使用高质量的钢，导致更高的疲劳强度，优化的X位置热处理和均匀的南京NSK轴承负荷分布。Duetogoodperformance,two-pointNanjingNSKbearingringrollerbearingsandsphericalrollerbearingswerepre-assignedforuseinnew8MWmodularwindturbinesandgearboxes.Basedonthehollowshaftdesign,rollerbearingsof1700to1800mmindiameterandsphericalrollerbearingsof1200to1300mmindiametercanbeused.Bearing.Italsoprovidesanewgenerationofrollerbearingsandsphericalrollerbearings.Theperformanceparametersofbearingh***ebeengreatlyimprovedindurability,operationabilityanddynamicbearingcapacity.Performanceimprovementsareattributedtotheuseofhighqualitysteel,resultinginhigherfatiguestrength,optimizedX-positionheattreatmentanduniformloaddistributionforNanjingNSKbearings.它还面临着为轴承尺寸提供个性化轴承座设计的挑战。在设计中，充分考虑了支承块的受力和变形，获得了更效率的载荷分布。此外，接触式或迷宫式密封可以根据润滑或（可能将来使用油润滑）集成到轴承座中。Italsofacesthechallengeofprovidingpersonalizedbearingblockdesignforbearingdimensi***.Inthedesign,theloadanddeformationofthesupportingblockarefullytakenintoaccount,andamoreefficientloaddistributionisobtained.Inaddition,contactorlabyrinthsealscanbeintegratedintothebearingseataccordingtolubricationor(possiblyfutureuseofoillubrication).一般来说，在运行之前，南京NSK轴承设备的转子须是静态的和动态的。万向轴承没有问题。但是，一些转子在运行中由于腐蚀或固体杂质磨损，或轴弯曲，会导致离心力不平衡，使轴承发热、振动、滚道磨损严重，直至损坏。Generallyspeaking,beforerunning,therotorofNanjingNSKbearingequipmentmustbestaticanddynamic.Thereisnoproblemwithuniversalbearings.However,somerotorsinoperationduetocorrosionorsolidimpuritieswear,orshaftbending,willleadtounbalancedcentrifugalforce,sothatbearingheating,vibration,racewaywearserious,untildamage.操作时，按规定定期检查万向节轴承。如有发热、异常声音和振动，及时停机，查明原因并排除故障。如果严重的疲劳剥落、氧化锈、磨损坑、裂纹、轴承硬度降低到HRC<60，或者噪声太大，不能调节，则应停止。时间的变化。如果检查和更换不及时，将造成严重的损坏甚至轴承转子，从而影响正常生产。此外，南京NSK轴承拆卸不当，设备脚螺栓因振动松动，还会导致轴承滚道和滚动压痕，轴承内外座圈产生裂纹。Duringoperation,theuniversaljointbearingsareregularlycheckedaccordingtotheregulati***.Ifthereisfever,abnormalsoundandvibration,stopintime,identifythecauseandtroubleshoot.Ifseriousfatiguespalling,oxidationrust,wearpits,cracks,bearinghardnessisreducedtoHRC<60,orthenoiseistoolargetoadjust,itshouldbestopped.Thechangeoftime.Iftheinspectionandreplacementisnottimely,itwillcauseseriousdamageorevenbearingrotor,thusaffectingnormalproduction.Inaddition,NanjingNSKbearingdisassemblyimproper,equipmentfootboltvibrationloosening,butalsoleadtobearingracewayandrollingindentation,bearinginnerandouterseatringcracks.文章来自：南京SKF轴承www.wh-文章来自：南京INA轴承a-文章来自：南京NSK轴承***：524085168电话：0510-81207777手机：13311666672)
