【正文】 l Committee of the Communist Party of China formally issued two regulations. Can say, two laws amendment concentrated the wisdom of the whole party, embodies the party. Second, code and Regulations revision of the basic principles of two party regulations revision work and implement the party39。 follow the correct direction, grasp the limited goals, adhere to the party39。因此，噪聲等級的劃分有助于工業(yè)標準的改進?？刹煊X的凹坑是一種制造缺陷，它是在制造過程中由于多爪卡盤夾的太緊而形成的。即用um/rad表示的軸承位移。如果軸承過熱，它將會卡住。和重復(fù)性振擺不同的是，NRR是沒有辦法進行補償?shù)摹＿@些特征包括噪聲、起動和運轉(zhuǎn)扭矩、剛性、非重復(fù)性振擺以及徑向和軸向間隙。當軸承從試驗機上取下來的時候可以現(xiàn)做一個初步的研究，將會在30倍顯微鏡下觀察失效的部分。因此在分析結(jié)果的時候就必須考慮是標準的軸承鋼還是專門的實驗用鋼材。而具有這樣能力的系統(tǒng)可以從早期就檢測出在多樣化工作條件復(fù)雜系統(tǒng)中用來測試用的缺陷軸承。這樣也會減少軸承壽命試驗的時間。3186。因此，如果一種潤滑劑用于長時間的軸承壽命實驗的話，生產(chǎn)者應(yīng)該定期更換實驗的樣品，比如一年一次。實驗人員必須保證整個實驗過程的連續(xù)性，由于任何微小的變化都會影響實驗結(jié)果，因此這個過程是很復(fù)雜的。潤滑劑的化學(xué)成分也是需要考慮的。如果工況選擇的范圍不確定，就必須考慮到接觸面積對實驗結(jié)果的影響。實驗者必須控制實驗過程以確保結(jié)果。但是一個被損壞的軸承，會留下它為什么被損壞的線索。關(guān)于這點Sayles和MacPherson以及其他人都有詳細的論證。這是由于軸承的溝道和滾動面之間會產(chǎn)生氫脆現(xiàn)象，從23章中也可以看出在潤滑實驗中濕氣是如此重要的一個因素。為了保證同組產(chǎn)品壽命試驗的結(jié)果有連貫性，最好在整個壽命試驗中都用同一供應(yīng)商的標準潤滑劑?，F(xiàn)在已經(jīng)知道了一些添加劑在長期使用時會造成大量的額外損耗。因此，所有軸承受溫度變化的影響會直接影響到壽命試驗數(shù)據(jù)的準確性。這樣的改變會影響幾何形狀的。為了檢測這個缺陷就需要使這個缺陷遞增到能影響軸承參數(shù)的數(shù)量級別。標準的軸承鋼在耐久性實驗中缺陷的遞增速度是相當快的。Tallian將所有軸承失效的黑白圖片匯編起來【】，可以為判斷各種類型的失效提供依據(jù)。這可以在選用過程中通過考慮關(guān)鍵性能特征來實現(xiàn)。保持架的尺寸誤差和軸承圈與滾珠的偏心都會引起NRR。一旦軸承受到污染，潤滑劑就要變質(zhì)，運行噪聲也隨之變大。測量噪聲的單位為anderons。~10次，它們是由各種干涉（例如軸承圈滾道上的凹坑）引起的。但ABEC等級并不能反映其他軸承特性，如軸承圈質(zhì)量、粗糙度、噪聲等。 the fourth part on how to grasp the implementation of the two regulations of the party. code and Regulations revised the necessity and revised history of the CPC Central Committee the amendment to the Chinese Communist Party members and leading cadres honest politics several guidelines and Chinese Communist Party discipline and Punishment Regulations column 1 by 2015 to strengthen party laws and regulations focus. Two party regulations revision work lasted a Years, pooling the wisdom of the whole party, ideological consensus, draw historical experience, respect for the wisdom of our predecessors, which reflects the unity of inheritance and innovation。 two is the political discipline regulations is not prominent, not specific, for violation of the party constitution, damage the authority of Party Constitution of misconduct lack necessary and serious responsibility to pursue。s eighteen, ten eight plenary, the spirit of the Fourth Plenary Session of the Eleventh Central Committee and General Secretary Xi Jinping important instructions on the revised low political criterion and Regulations , highlighting the ruling party characteristics, serious discipline, the discipline quite in front of the law, based on the current, a longterm, advance as a whole, with Bu Xiuding independent rule and rule . Main principle is: first, adhere to the party constitution to follow. The constitution about discipline and selfdiscipline required specific, awaken the party constitution of party passes party consciousness, maintaining the authority of the constitution. General Secretary Xi Jinping pointed out that no rules, no side round. Party constitution is the fundamental law, the party must follow the general rules. In early 2015 held the eighth session of the Central Commission for Discipline Inspection Fifth Plenary Session of the 16th Central Committee, Xi Jinping again pointed out that constitution is the party must follow the general rules, but also the general rules. the revision of the code and rule is Method in adhere to the regulations established for the purpose of bining rule of virtue is to adhere to the party constitution as a fundamental to follow, the constitution authority set up, wake up the party constitution and party rules the sense of discipline, the party constitution about discipline and selfdiscipline specific requirements. 4 second is to adhere to in accordance with the regulations governing the party and the party. The Party of rule of virtue de, mainly refers to the party39。s leadership, to solve the masses of the people reflect a focus on the problem. The new revision of the code and rule , reflects the party39。BEARING LIFE ANALYSISProceedings of the Ninth International Symposium on Magnetic Bearings. Kentucky. USA. 2004,(August):361 .WHY BEARINGS FAILAn individual bearing may fail for several reasons。中頻噪聲的特征是軸承每旋轉(zhuǎn)一周不規(guī)則變化出現(xiàn)10~60次。根據(jù)經(jīng)驗，觀察者可以根據(jù)聲音辨別出微小的缺陷。當污染物處于滾珠和軸承圈之間時，其作用和金屬表面之間的磨粒一樣，會使軸承磨損。在工業(yè)中一般是根據(jù)具體的應(yīng)用來選擇不同類型和精度等級的軸承。扭矩要求是由潤滑劑、保持架、軸承圈質(zhì)量（彎曲部分的圓度和表面加工質(zhì)量）以及是否使用密封或遮護裝置來決定。元素金相實驗可以提供一個精確的證據(jù)，使實驗結(jié)果處于可控制情況下，同時檢測有疑點和爭議的地方。有的也不一定，比如一些表面硬度不同的鋼材或是專為實驗用生產(chǎn)的鋼材?？梢栽谙到y(tǒng)中應(yīng)用這些技術(shù)方法來檢驗缺陷。腐蝕是由于震動產(chǎn)生的微粒被氧化而產(chǎn)生的。因此對于軸承壽命試驗時177。一般的對潤滑劑做化學(xué)檢測時是不會檢測添加劑的成分的。因此一個軸承的壽命試驗需很長的時間。為了降低對壽命減少的影響，潮氣的含量最多不能超過40PPM。潤滑劑的選擇由工況決定，實驗時也如此。關(guān)鍵詞：軸承 失效 壽命1 .軸承失效的原因軸承失效有以下多種原因，然而軸承的壽命實驗卻是所有機械實驗中最有意義的。通過一些細致的觀察工作，我們可以采取行動來避免軸承的再次失效。因此，為了確保實驗結(jié)果我們必須選用合適等級的潤滑劑。因此在軸承壽命的試驗結(jié)果中必須考慮到潮氣的影響。為了得到一個合理的結(jié)果，統(tǒng)計學(xué)要求做很多組壽命試驗。這些易退化的添加劑會影響軸承表面的潤滑條件，從而影響軸承的壽命。因此為了保證實驗數(shù)據(jù)的連貫性，必須監(jiān)控并實時調(diào)節(jié)每個軸承的使用溫度。軸外徑和軸承內(nèi)徑都會受腐蝕的影響。比如說噪音，溫度，震動等缺陷。而且這個遞增還不是主要因素，考慮到有代表性的耐久性實驗的數(shù)據(jù)都是經(jīng)統(tǒng)計學(xué)分析后得到的。現(xiàn)在Tallian已經(jīng)將其更新為【】，其中加入了彩色圖片。2 .避免失效的方法解決軸承失效問題的最好辦法就是避免失效發(fā)生。在軸承轉(zhuǎn)動過程中，如果內(nèi)圈和外圈之間存在一個隨機的偏心距，就會產(chǎn)生與凸輪運動非常相似的非重復(fù)性振擺（NRR）。但是，由于軸承內(nèi)外圈的運動，使軸承的密封不可能達到完美的程度，因此潤滑油的泄漏和污染始終是一個未能解決的問題。將一傳感器連接在軸承外圈上，而內(nèi)圈在心軸以1800r/min的轉(zhuǎn)速旋轉(zhuǎn)。低頻噪聲是長波段不規(guī)則變化的結(jié)果。隨著ABEC級別的增加（從3增到9），公差逐漸變小。 the third part introduces two party regulations modified the main changes and needs to grasp several key problems。 the fourth is to clean the theme is not prominent, not for the existing problems, and is narrow, only needle of countylevel leading cadres above. rule is in 1997 Chinese Communist Party disciplinary cases (Trial) based on revision, in December 2003 the promulgation and implementation, to strengthen the construction of the party play very important role. Along with the development of the situation, which many provisions have been unable to fully meet the prehensive strictly administering the practice needs. One is Ji law, more than half of the provisions and criminal law and other countries laws and regulations Repeti
