建议将泰州SKF轴承旋转环的点火干扰降低到较小的程度。只要在工作温度下保证热膨胀效应和**大离心力，紧密匹配的表面就不会蠕变或滑动。固定环根据工作负荷和轴承尺寸选择**小间隙配合或过盈配合。太松或太紧不利于保持原有精*确的形状。ItissuggestedthattheignitioninterferenceofSKFbearingrotatingringinTaizhoushouldbereducedtoalesserextent.Aslongasthethermalexpansioneffectand**largecentrifugalforceareguaranteedatworkingtemperature,thetightlymatchedsurfaceswillnotcreeporslip.Fixedringsareselectedwith*****allclearancefitorinterferencefitaccordingtoworkloadandbearingsize.Toolooseortootightisnotconducivetomaintainingtheoriginalpreciseshape.旋转环配合和固定环配合的干涉计算需要精*确。Theinterferencecalculationofrotatingringfitandfixedringfitneedstobepreciseandaccurate.根据泰州SKF轴承的相应精度，要求轴和座孔的圆度和肩部的垂直度。AccordingtothecorrespondingaccuracyofTaizhouSKFbearing,theroundnessofshaftandseatholeandtheverticalityofshoulderarerequired.采用特殊的装配工具，确保保持架和轴承的装配精度。Specialassemblytoolsareusedtoensuretheassemblyaccuracyofcagesandbearings.固定环小过盈配合的条件是匹配面两侧的形状精度高，粗糙度小。否则，安装和拆卸将变得更加困难。此外，还应考虑主轴热伸长的影响。Theconditionof***allinterferencefitoffixedringisthattheshapeaccuracyofbothsidesofthematchingsurfaceishighandtheroughnessis***all.Otherwise,installationanddisassemblywillbecomemoredifficult.Inaddition,theinfluenceofthermalelongationofspindleshouldalsobec***idered.在匹配时，应将摆动载荷和不确定载荷视为与旋转载荷相同。松动匹配会损坏匹配表面。Whenmatching,theswingloadandtheuncertainloadshouldberegardedasthesameastherotatingload.Loosematchingcandamagethematchingsurface.对于沿载荷方向旋转的环和轴或座孔，应选择过渡配合或过盈配合。这种干涉是基于轴承在负载下工作时，在泰州SKF轴承轴或座孔中的环的配合表面上不存在“蠕变”现象的原理。当负载很轻或者当环在重负载下偶尔以低速旋转时，可以选择过渡配合。此时，轴表面应具有较高的硬度和较小的表面粗糙度。Transitionfitorinterferencefitshouldbeselectedforringsandaxesorseatholesrotatingalongloaddirection.Thisinterferenceisbasedontheprinciplethatthereisno"creep"phenomenononthematingsurfaceoftheringintheshaftorseatholeofSKFbearinginTaizhouwhenthebearingworksunderload.Transitionfitcanbeselectedwhentheloadisverylightorwhentheringoccasionallyrotatesatalowspeedunderhe***yload.Atthistime,theshaftsurfaceshouldh***ehigherhardnessand***allersurfaceroughness.采用斜接触球轴承主轴时，大部分载荷较小。如果配合过盈量大，内部轴向预紧力将显著增加，从而产生不利影响。双列短圆柱滚子轴承和圆锥滚子轴承具有较大的主轴载荷和较大的匹配干涉。Whenusingobliquecontactballbearingspindle,mostoftheloadis***all.Ifthefitinterferenceislarge,theinternalaxialpre-tighteningforcewillincreasesignificantly,whichwillh***eadverseeffects.Doublerowshortcylindricalrollerbearingsandtaperedrollerbearingsh***elargerspindleloadandlargermatchinginterference.有时不能准确地确定泰州SKF轴承负载的方向和大小。例如，在高速旋转机械中，除了转子重量固定的负载外，还存在由质量不平衡引起的旋转负载。如果旋转载荷远大于固定载荷，则复合载荷仍将是旋转载荷；如果旋转载荷大于固定载荷，则复合载荷仍将是旋转载荷。如果载荷远小于固定载荷，则复合载荷是摆动载荷。无论是旋转载荷还是摆动载荷，轴承的尺寸和方向都在不断地变化。在不同的工作条件下，一些环可能受到旋转、固定和摆动载荷。这种荷载称为不定荷载。Sometimes,thedirectionandsizeofSKFbearingloadinTaizhoucannotbeaccuratelydetermined.Forexample,inhigh-speedrotatingmachinery,besidestheloadwithfixedrotorweight,therearealsorotatingloadscausedbymassimbalance.Iftherotatingloadismuchlargerthanthefixedload,thecompositeloadwillstillbetherotatingload;iftherotatingloadislargerthanthefixedload,thecompositeloadwillstillbetherotatingload.Iftheloadismuchlessthanthefixedload,thecompositeloadistheswingload.Whetherrotatingloadorswingload,bearingsizeanddirectionarec***tantlychanging.Underdifferentworkingconditi***,someringsmaybesubjectedtorotating,fixedandswingloads.Thiskindofloadiscalledindefiniteload.文章来自：泰州SKF轴承www.wh-文章来自：泰州INA轴承a-文章来自：泰州NSK轴承***：524085168电话：0510-81207777手机：13311666672/13395185757)
