如何提高进口淮安INA轴承的安装精度？HowtoimprovetheinstallationaccuracyofimportedHuaianINAbearings?如何提供安装精度直接影响进口轴承的使用寿命。为了延长进口轴承的使用寿命，安装是必不可少的一步。因此，在安装轴承之前，首先要确定轴承的安装精度，然后寻找提高轴承安装精度的方法。Howtoprovideinstallationaccuracydirectlyaffectstheservicelifeofimportedbearings.Inordertoprolongtheservicelifeofimportedbearings,installationisanindispensablestep.Therefore,beforeinstallingbearings,weshouldfirstdeterminetheinstallationaccuracyofbearings,andthenfindwaystoimprovetheinstallationaccuracyofbearings.（1）测量轴和轴承座孔的尺寸，以确定轴承的匹配精度。匹配要求如下：内环与轴采用过盈配合，过盈量为0-4微米（轻载，高精度为0）；外环与轴承座孔采用过盈配合，过盈量为0-6微米（但采用角接触球轴承时可增大间隙）。zi由端；轴与座孔表面圆度误差为2。微米以下，淮安INA轴承隔膜端面平行度小于2微米，轴肩内端面小于2微米，轴承座孔肩外端面小于4微米，主轴前盖内端面小于4微米。(1)Measurethedimensi***oftheshaftandbearingseatholestodeterminethematchingaccuracyofthebearing.Thematchingrequirementsareasfollows:interferencefitisusedforinnerringandshaft,theinterferenceamountis0-4micron(lightload,highprecisionis0);interferencefitisusedforouterringandbearingseathole,theinterferenceamountis0-6micron(buttheclearancecanbeincreasedwhenangularcontactballbearingisused).Theroundnesserrorofthesurfaceoftheshaftandtheseatholeis2.Undermicron,HuaianINAbearingdiaphragmend-faceparalleli***islessthan2micron,shaftshoulderinnerend-faceislessthan2micron,bearingseatholeshoulderouterend-faceislessthan4micron,spindlefrontcoverinnerend-faceislessthan4micron.（2）安装轴固定端前轴承：用干净的煤油彻底清洗轴承。对于油脂润滑，将含有3~5个百分点油脂的you机溶剂注入轴承进行脱脂和清洗，然后用油枪将定量油脂注入轴承（轴承空间体积的10~15个百分点。轴承加热到20-30摄氏度，然后用液压机装入轴端。将固定套压在轴上，在轴承的端面施加适当的压力，使其轴向***；将弹簧秤的胶带卷在轴承的外圈上，测量起动力矩，淮安INA轴承检查规定的预紧力是否发生了很大变化（即使轴承S正确，预紧力由于配合或保持架的变形，ad可能会发生变化）。(2)Installthefrontbearingofthefixedendoftheshaft:cleanthebearingthoroughlywithcleankerosene.Forgreaselubrication,youmachinesolventcontaining3-5%greaseisinjectedintobearingfordegreasingandcleaning,andthenquantitativegreaseisinjectedintobearing(10-15%ofbearingspacevolume)withoilgun.Thebearingisheatedto20-30degreesCelsiusandthenloadedintotheshaftendwithahydraulicpress.Thefixedsleeveispressedontheaxle,andproperpressureisappliedontheendfaceofthebearingtomakeitaxiallypositioned;thetapeofthespringbalanceisrolledontheouterringofthebearingtomeasurethestartingmoment.HuaianINAbearingcheckswhethertheprescribedpreloadhaschangedgreatly(evenifthebearingSiscorrect,thepreloadmaychangeduetothedeformationofthematingorcage).（3）将进口轴承轴总成装入座孔：将座孔加热至20-30摄氏度，将轴承轴总成连续轻压入座孔，调整前盖，将前盖紧固至0.02-0.05微米，以轴承座外端面为基准。另一方面，表盘头部与轴颈表面碰撞，其跳动量由旋转轴测量。误差小于10um。头部位于轴线上，与后座孔内表面接触，转动轴，测量淮安INA轴承座前后座孔的同轴度。(3)Installtheimportedbearingshaftassemblyintotheseathole:heattheseatholeto20-30degreesCelsius,pressthebearingshaftassemblyintotheseatholecontinuouslyandlightly,adjustthefrontcover,fastenthefrontcoverto0.02-0.05micron,andbaseontheouterendfaceofthebearingseat.Ontheotherhand,theheadofthedialcollideswiththesurfaceofthejournal,anditsrunoutismeasuredbytherotatingaxis.Theerrorislessthan10um.Theheadislocatedontheaxis,contactswiththeinnersurfaceoftherearseathole,rotatestheshaft,andmeasuresthecoaxialityofthefrontandrearseatholesofHuaianINAbearingseat.（4）zi由端轴承有选择地***在偏移位置，安装在轴承座后支撑位置，尽可能地偏移圆度和同轴度偏差。(4)Ziisselectivelypositionedattheoffsetpositionbytheendbearingandinstalledatthebacksupportpositionofthebearingseattooffsettheroundnessandcoaxialitydeviationasfaraspossible.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)
