在主机上安装淮安NSK轴承后，如果测量轴承主轴的径向跳动，可以发现每一个转动的测量值都有一定的变化；连续测量时，可以发现，经过一定的转动后，变化将近似重复。测量变化程度的指标是圆旋转的精度。重复旋转近似于循环旋转精度的准周期性。准周期变化范围大，即周期旋转精度差。AfterinstallingtheHuaianNSKbearingonthemainengine,iftheradialrunoutofthebearingspindleismeasured,itcanbefoundthatthemeasuredvalueofeachrotationhasacertainchange;whencontinuouslymeasuring,itcanbefoundthatafteracertainrotation,thechangewillbeapproximatelyrepeated.Theindexofmeasuringthedegreeofchangeistheaccuracyofcircularrotation.Repeatedrotationapproximatesthequasi-periodicityofcyclicrotationaccuracy.Therangeofquasi-periodicvariationislarge,thatis,theprecisionofperiodicrotationispoor.如果对轴承主轴施加适当的预紧力，转速将逐渐提高，接近工作转速，从而实现轴承的“磨合”功能，提高主轴旋转精度。Ifproperpreloadingforceisappliedtothebearingspindle,thespeedwillgraduallyincrease,closetotheworkingspeed,thusrealizingthe"running-in"functionofthebearingandimprovingthespindlerotationaccuracy.轴承安装后，为了检查安装是否正确，应进行操作检查。小型机器可以用手旋转以确保平稳旋转。淮安NSK轴承检查项目包括：***、伤痕、操作bu良造成的压痕、安装.bu良、力矩不稳定造成的安装座加工bu良、间隙过小、安装误差、力矩过大造成的密封摩擦等，如无异常，可启动供电运行。Afterthebearingisinstalled,inordertocheckwhethertheinstallationiscorrect,theoperationinspectionshouldbecarriedout.***allmachinescanberotatedbyhandtoensure***oothrotation.HuaianNSKbearinginspectionitemsinclude:foreignbody,scar,indentationcausedbyoperationBuLiang,installationBuLiang,installationseatprocessingBuLiangcausedbyunstablemoment,too***allclearance,installationerror,sealingfrictioncausedbyexcessivemoment,etc.Ifthereisnoabnormality,powersupplyoperationcanbestarted.大型机械不能手动旋转。空载启动后立即切断电源。机器闲置。检查转动部件的振动、噪声和接触情况，确认无异常，进入动力运行。Largemachinerycannotrotatemanually.Cutoffthepowersupplyimmediatelyafterno-loadstart-up.Themachineisidle.Checkthevibration,noiseandcontactoftherotatingparts,confirmthatthereisnoabnormality,andenterthepoweroperation.当电源运行时，空载、低速启动，并缓慢增加到规定的额定工作条件。在调试过程中，检查项目包括异常噪音、淮安NSK轴承温度变化、润滑油泄漏或变色。如果发现任何异常，应立即停止机器，必要时应拆下轴承进行检查。Whenthepowersupplyisrunning,no-load,low-speedstart,andslowlyincreasetothespecifiedratedworkingconditi***.Duringcommissioning,theinspectionitemsincludeabnormalnoise,temperaturechangeofHuaianNSKbearing,oilleakageordiscoloration.Ifanyabnormalitiesarefound,themachineshouldbestoppedimmediatelyandthebearingsshouldberemovedforinspectionifnecessary.轴承温度通常可以从轴承座的外部温度推断出来。但采用油孔直接测量轴承外圈温度更为准确。轴承温度从运行开始逐渐升高，通常在温度稳定后1至2小时。如果轴承安装不当，温度会急剧上升，出现异常高温。其原因包括润滑油过多、轴承间隙过小、安装.bu良、密封装置摩擦过大、轴承结构选择不当、润滑方式不合理等，也是高速旋转的原因。Bearingtemperaturecanusuallybededucedfromtheexternaltemperatureofthebearingseat.Butitismoreaccuratetouseoilholetomeasurethetemperatureofbearingouterringdirectly.Bearingtemperaturegraduallyincreasesfromthebeginningofoperation,usually1to2hoursaftertemperaturestabilization.Ifthebearingisnotproperlyinstalled,thetemperaturewillrisesharplyandabnormalhightemperaturewilloccur.Thereas***includetoomuchlubricatingoil,too***allbearingclearance,goodinstallation.bu,toomuchfrictionofsealingdevice,improperselectionofbearingstructure,unreasonablelubricationmodeandsoon,whicharealsothereas***forhigh-speedrotation.***检测淮安NSK轴承的旋转声音。结果表明，金属噪声较大，声音异常。其原因包括润滑bu良、轴或轴承座精度差、轴承损坏、******等。StethoscopedetectstherotatingsoundofHuaianNSKbearing.Theresultsshowthatthemetalnoiseislargeandthesoundisabnormal.Thereas***includegoodlubricationbu,poorprecisionofshaftorbearingseat,bearingdamage,foreignbodyintrusion,etc.文章来自：淮安SKF轴承www.wh-文章来自：淮安INA轴承a-文章来自：淮安NSK轴承***：524085168电话：0510-81207777手机：13311666672/13395185757)
