(1)可移性。聯(lián)軸器的可移性是指補(bǔ)償兩回轉(zhuǎn)構(gòu)件相對(duì)位移的能力。被連接構(gòu)件間的制造和安裝誤差、運(yùn)轉(zhuǎn)中的溫度變化和受載變形等因素，都對(duì)可移性提出了要求?？梢菩阅苎a(bǔ)償或緩解由于回轉(zhuǎn)構(gòu)件間的相對(duì)位移造成的軸、軸承、聯(lián)軸器及其他零部件之間的附加載荷。

1、動(dòng)力機(jī)的機(jī)械特性動(dòng)力機(jī)到工作機(jī)之間，通過一個(gè)或數(shù)個(gè)不同品種型號(hào)、規(guī)格的聯(lián)軸器將主、從動(dòng)端聯(lián)接起來，形成軸系傳動(dòng)系統(tǒng)。由于動(dòng)力機(jī)工作原理和機(jī)構(gòu)不同，其機(jī)械特性差別較大，對(duì)傳動(dòng)系統(tǒng)形成不等的影響。不同類別的動(dòng)力機(jī)，由于其機(jī)械特性不同，應(yīng)選取相應(yīng)的動(dòng)力機(jī)系數(shù)KW，選擇適合于該系統(tǒng)的較佳聯(lián)軸器。動(dòng)力機(jī)的類別是選擇聯(lián)軸器品種的基本因素，動(dòng)力機(jī)的功率是確定聯(lián)軸器性能的主要依據(jù)之一，與聯(lián)軸器轉(zhuǎn)矩成正比。 2、糾偏能力糾偏能力是指彈性聯(lián)軸器其彈性體本身所具有的彈性能承受的徑向、角向、軸向的恢復(fù)能力。根據(jù)機(jī)械和使用場合本身需求連接的精密度、誤差的不同，選用不同糾偏能力的聯(lián)軸器，來糾正機(jī)械產(chǎn)生的誤差，達(dá)到延長電機(jī)和絲桿或其它傳動(dòng)器件的使用壽命。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(yùn)動(dòng)強(qiáng)烈，故易流動(dòng)。</p><div

如果總的有效斷面或平均流速沿流程不變，各有效斷面上相應(yīng)點(diǎn)的流速業(yè)不變，且流線為平行直線，這樣的穩(wěn)定流動(dòng)稱為均勻流。均勻流中沒有加速度，因而不存在慣性力。當(dāng)有效斷面沿流程變化，或者有效斷面不變，但各斷面上速度分布改變時(shí)這種流動(dòng)稱為非均勻流。例如，有效斷面收縮或擴(kuò)大處、圓管轉(zhuǎn)彎處、流線為夾角不同的曲線或直線等都屬于非均勻流。非均勻流中有加速度，因而存在慣性力。如果有效斷面沿流程變化劇烈或斷面流速分布變化劇烈時(shí)，該流動(dòng)稱為急變流。流體的形狀可以是水滴的形狀，也可以是斷流的形狀，粘稠的形狀。這種形式的流體給人液體的質(zhì)感。江蘇軟管總成流體公接頭</p><p style="text-indent:25px">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。浙江輕型軟管流體設(shè)備廠家</p><p style="text-indent:25px">聯(lián)軸器的選型方法 1.根據(jù)機(jī)械特性的要求，如有無齒隙、抗扭剛度高低、振動(dòng)沖擊力吸收等等，選擇合適的聯(lián)軸器型式。 2.由驅(qū)動(dòng)機(jī)械（如電機(jī)）動(dòng)力 [KW,HP] 及聯(lián)軸器使用回轉(zhuǎn)數(shù) [N] 求得聯(lián)軸器承受的轉(zhuǎn)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(fù)載條件系數(shù) K1 ，運(yùn)轉(zhuǎn)時(shí)間系數(shù) K2 ，起動(dòng)停止頻度系數(shù) K3 ，周圍環(huán)境溫度系數(shù)K4 ，求得補(bǔ)正扭力 [TD] 。 TD=TA · K1 · K2 · K3 · K4 4.選用聯(lián)軸器的常用轉(zhuǎn)矩必須大于被正轉(zhuǎn)矩。 5.聯(lián)軸器所能承受的較大扭力必須大于原動(dòng)側(cè)及被動(dòng)側(cè)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(duì)于振動(dòng)頻率亦須檢討。即轉(zhuǎn)矩變動(dòng)的頻率與軸的固有振動(dòng)數(shù)避免造成共振的現(xiàn)象產(chǎn)生。浙江輕型軟管流體設(shè)備廠家</p></p><br /><p>文章來源地址:
