镇江NSK轴承是一种元件，广泛应用于各个领域，根据结构或类型分为多种，并根据摩擦特性来分类常见的滚动轴承和滑动轴承，两者都有所不同。滚动轴承的摩擦阻力远小于滑动轴承的摩擦阻力。它具有启动快、效率高的优点。与滑动轴承相比，滚动轴承是大的优点。但是也有缺点，即尺寸较大，所以吸收振动的能力较弱，在高速运行时间较短，长期使用也会发出较大的异常声音。滚动轴承和滑动轴承的另一个本质区别是滚动轴承是表面接触，而滑动镇江NSK轴承是点接触。滚动轴承接触面大，结构简单，操作拆卸方便，对滑动轴承的润滑要求高。ZhenjiangNSKbearingisakindofcomponent,whichiswidelyusedinvariousfields.Itisdividedintomanykindsaccordingtoitsstructureortype,andclassifiescommonrollingbearingsandslidingbearingsaccordingtotheirfrictioncharacteristics.Bothofthemaredifferent.Thefrictionresistanceofrollingbearingsismuch***allerthanthatofslidingbearings.Ithastheadvantagesoffaststartupandhighefficiency.Comparedwithplainbearings,rollingbearingisagreatadvantage.Buttherearealsodrawbacks,thatis,thelargersize,sotheabilitytoabsorbvibrationisweak,inhigh-speedrunningtimeisshort,long-termusewillalsoemitalargerabnormalsound.Anotheressentialdifferencebetweenrollingbearingsandslidingbearingsisthattherollingbearingsaresurfacecontact,whiletheslidingZhenjiangNSKbearingsarepointcontact.Rollingbearinghaslargecontactsurface,simplestructure,convenientoperationanddisassembly,andhighlubricationrequirementforslidingbearings.当双向推力球轴承在拆卸检查后损坏时，可根据轴承的损坏程度来判断故障和轴承损坏。Whenthetwo-waythrustballbearingisdamagedafterdisassemblyinspection,thefaultandbearingdamagecanbejudgedaccordingtothedamagedegreeofthebearing.在周期性波动载荷下，内外滚道表面发生周期性接触应力变化。当应力循环次数达到一定值时，疲劳剥落发生在轧制面或内外滚道上。如果轴承载荷过大，则会加剧疲劳。此外，如果镇江NSK轴承错位，轴弯曲，滚道就会脱落。轴承滚道的疲劳剥落会降低轴的工作精度，引起振动和噪声机理。Undercyclicloading,periodiccontactstresschangesontheinnerandouterracewaysurfaces.Whenthenumberofstresscyclesreachesacertainvalue,fatiguepeelingoccursontherollingsurfaceorinsideandoutsideraceway.Ifthebearingloadistoolarge,itwillaggr***atefatigue.Besides,iftheNSKbearingofZhenjiangismisplacedandtheshaftisbent,theracewaywillfalloff.Thefatiguepeelingofthebearingracewaywillreducetheworkingaccuracyoftheshaftandcausethevibrationandnoisemechani***.燃烧轴承在滚道和滚动体上有回火颜色。温高通常是由于润滑不足，润滑不顺或恶化，以及过度轴承装配。Thecombustionbearingsh***etemperingcolorsonracewayandrollingbody.Hightemperatureisusuallyduetoinadequatelubrication,poorlubricationordeterioration,andexcessivebearingassembly.镇江NSK轴承滚道与接触面的滚动面之间出现凹痕，表明轴承存在塑性变形。其原因是，这通常发生在低速轴承在静态或冲击载荷下，其中工作表面上的局部应力超过材料的屈服极限。ThedentbetweentheNSKbearingracewayofZhenjiangandtherollingsurfaceofthecontactsurfaceindicatesthatthebearinghasplasticdeformation.Thereasonisthatthisusuallyoccursinlow-speedbearingsunderstaticorimpactloads,wherethelocalstressontheworkingsurfaceexceedstheyieldlimitofthematerial.轴承套圈开裂是造成轴承配合过大、内外圈松动、轴承座变形、轴承表面安装和加工异常的主要原因。Bearingringcrackingisthemainreasonforexcessivebearingfit,looseningofinnerandouterrings,bearingseatdeformation,bearingsurfaceinstallationandmachiningabnormalities.其原因是润滑不足，滚动体断裂，阀座环歪斜等。Thereasonisthatthelubricationisinsufficient,therollingbodyisbroken,theseatringisskewed,etc.可能的原因是滚子卡在笼子里或不够润滑。Thepossiblereasonisthatrollersarestuckincagesornotlubricatedenough.可能是落在阀座上的***、镇江NSK轴承润滑油不足或润滑油水平不当。Itmaybeaforeignobjectfallingonthevalveseat,insufficientlubricatingoilinZhenjiangNSKbearingorimproperlubricatingoillevel.载荷、润滑、装配、环境条件、材料质量或制造精度是影响双向推力球轴承损坏的主要因素。Load,lubrication,assembly,environmentalconditi***,materialqualityormanufacturingaccuracyarethemainfactorsaffectingthedamageofbi-directionalthrustballbearings.文章来自：镇江SKF轴承www.wh-Thearticleisfrom:ZhenjiangSKFbearingwww.wh-文章来自：镇江INA轴承a-Thearticleisfrom:ZhenjiangINAbearinga-文章来自：镇江NSK轴承Thearticleisfrom:ZhenjiangNSKbearing***：524085168电话：0510-81207777手机：13311666672)
