style="text-indent:25px">聯(lián)軸器的功能要求和分類：機器由動力機—傳動—工作機—控制器四個主要部分組成。聯(lián)軸器是用來連接其中兩軸或軸與回轉體，以傳遞運動和轉矩為基本功能的通用部件。聯(lián)軸器的兩個半聯(lián)軸器用軸轂連接固裝在主、從動軸上，在用連接件（剛體、彈性體）將兩個半聯(lián)軸器連接起來，形成剛性聯(lián)軸器和撓性聯(lián)軸器。前者只起連接兩軸傳遞運動和扭矩，不具備其它功能。用金屬或非金屬彈性元件連接的兩個半聯(lián)軸器，江蘇輕型軟管流體設備，江蘇輕型軟管流體設備，分別稱為具有金屬彈性元件的撓性聯(lián)軸器和非金屬彈性元件的撓性聯(lián)軸器，它們利用彈性元件的變形來補償兩軸線的相對偏移，江蘇輕型軟管流體設備，同時具有不同程度的減震、緩沖和改善傳動系統(tǒng)工作特性的功能。能起過載安全保護作用的稱為安全聯(lián)軸器。所有聯(lián)軸器只能在停機狀態(tài)下通過裝拆才能使兩半聯(lián)軸器結合或分離。流體受壓力作用時體積縮小、密度增大的性質稱為流體的壓縮性。江蘇輕型軟管流體設備</p><div

style="text-indent:25px">無旋流動就是流體運動過程中流體質點無旋轉的流動。盡管有旋流動是自然界中普遍存在的，但在一些假設或某種近似條件***動還是可以視為無旋的。例如，對于無黏、正壓流體（流體密度*是壓力的函數(shù)即為正壓流體，如等溫、等熵流動假設，等密度流動是正壓流體的一個特例），當假設質量力有勢時，均勻來流繞流物體運動或從靜止狀態(tài)開始的流動就屬于無旋流動。無旋流動的重要意義在于，無旋條件下可以得到速度的勢函數(shù)，如果再假設流體是不可壓縮的，就可以得到速度勢的拉普拉斯方程，它在數(shù)學上有成熟的方法處理。因此無旋流動也是一種應用普遍的簡化模型。浙江軟管流體產(chǎn)品元件在工程計算中亦常常采用流體的動力粘度與其密度的比值稱為運動粘度或運動粘滯系數(shù)。</p><div

style="text-indent:25px">聯(lián)軸器安裝前先把零部件清洗干凈，清洗后的零部件，需把沾在上面的洗油擦干。在短時間內準備運行的聯(lián)軸器，擦干后可在零部件表面涂些透平油或機油，防止生銹。對于需要過較長時間投用的聯(lián)軸器，應涂以防銹油保養(yǎng)。聯(lián)軸器的結構型式很多，具體裝配的要求、方法都不一樣，對于安裝來說，總的原則是嚴格按照圖紙要求進行裝配，具體的只能介紹一些聯(lián)軸器裝配中經(jīng)常需要注意的問題。對于應用在高速旋轉機械上的聯(lián)軸器，一般在制造廠都做過動平衡試驗，動平衡試驗合格后畫上各部件之間互相配合方位的標記。如果不按標記任意組裝，很可能發(fā)生由于聯(lián)軸器的動平衡不好引起機組振動的現(xiàn)象。</p><p style="text-indent:25px">聯(lián)軸器的選型方法 1.根據(jù)機械特性的要求，如有無齒隙、抗扭剛度高低、振動沖擊力吸收等等，選擇合適的聯(lián)軸器型式。 2.由驅動機械（如電機）動力 [KW,HP] 及聯(lián)軸器使用回轉數(shù) [N] 求得聯(lián)軸器承受的轉矩 [TA] TA(Kg.m)=973.5×KW/N(rpm)=716.2×HP/N(rpm)或 TA(N·m)=9550×KW/N(r/min) 3.由被正系數(shù)表中查得負載條件系數(shù) K1 ，運轉時間系數(shù) K2 ，起動停止頻度系數(shù) K3 ，周圍環(huán)境溫度系數(shù)K4 ，求得補正扭力 [TD] 。 TD=TA · K1 · K2 · K3 · K4 4.選用聯(lián)軸器的常用轉矩必須大于被正轉矩。 5.聯(lián)軸器所能承受的較大扭力必須大于原動側及被動側雙方所產(chǎn)生的較大扭力。 6.確定孔徑范圍是否適用。 7.除了以上的選定步驟外，對于振動頻率亦須檢討。即轉矩變動的頻率與軸的固有振動數(shù)避免造成共振的現(xiàn)象產(chǎn)生。在流體中任意點處的密度均相同，則該流體為均勻流體。</p><div

style="text-indent:25px">聯(lián)軸器是將兩軸軸向聯(lián)接起來并傳遞扭矩及運動的部件并具有一定的補償兩軸偏移的能力，為了減少機械傳動系統(tǒng)的振動、降低沖擊尖峰載荷，聯(lián)軸器還應具有一定的緩沖減震性能。聯(lián)軸器有時也兼有過載安全保護作用。聯(lián)軸器屬于機械通用零部件范疇，用來聯(lián)接不同機構中的兩根軸（主動軸和從動軸）使之共同旋轉以傳遞扭矩的機械零件。在高速重載的動力傳動中，有些聯(lián)軸器還有緩沖、減振和提高軸系動態(tài)性能的作用。聯(lián)軸器由兩半部分組成，分別與主動軸和從動軸聯(lián)接。一般動力機大都借助于聯(lián)軸器與工作機相聯(lián)接，是機械產(chǎn)品軸系傳動較常用的聯(lián)接部件。20世紀后期國內外聯(lián)軸器產(chǎn)品發(fā)展很快，在產(chǎn)品設計時如何從品種甚多、性能各異的各種聯(lián)軸器中選用能滿足機器要求的聯(lián)軸器，對多數(shù)設計人員來講，始終是一個困擾的問題。常用聯(lián)軸器有膜片聯(lián)軸器，鼓形齒式聯(lián)軸器，萬向聯(lián)軸器，安全聯(lián)軸器，彈性聯(lián)軸器及蛇形彈簧聯(lián)軸器。流體流動存在兩種運動狀態(tài)：層流和湍流。浙江軟管總成流體控制</p><p style="text-indent:25px">一定體積***體分子數(shù)目少，分子間作用力小，分子的無規(guī)則熱運動強烈，故易流動。江蘇輕型軟管流體設備</p><p style="text-indent:25px">單項流體和多項流體: 單組分氣體、多組分氣體或彼此能溶解的液體都是單相流體，而固體顆粒、液體顆粒懸浮在氣體介質中，這樣的流體則為多相流。在除塵技術中，含塵氣體在管道中的流動過程可以按單相流體處理，而粉塵在除塵器中的分離過程則必需按多相流體處理。流體的壓縮性和膨脹性: 流體受壓力作用時體積縮小、密度增大的性質稱為流體的壓縮性。流體隨著溫度的升高體積膨脹、密度減小的性質，稱為流體的膨脹性。在工程上，對于氣流速度遠小于聲速且處于常溫常壓條件下的氣體，可近似地認為是不可壓縮的氣體。如在常溫常壓下工作的除塵器、風機、通風管道等裝置中的氣體都可按不可壓縮流體進行處理；而對于在高溫高壓下的流動的氣體則必需按可壓縮流體處理，否則將會導致較大誤差。江蘇輕型軟管流體設備</p></p><br
