style="text-indent:25px">有的卷簧常用來作平衡用。例如，在一個立式的導(dǎo)軌上安裝有一個部件，需要沿導(dǎo)軌上下移動，又要求在任意位置可以穩(wěn)定停住，部件的上下移動是靠一根鏈條拉動的，部件越向下，鏈條也隨著變長，由于鏈條也有重量，于是就比部件在導(dǎo)軌上端時要重了，由此造成了部件在上與下的不同位置，部件加鏈條的總重不同，對于這種不同位置的不平衡也可以用卷簧來附加平衡力。常見的盒尺也是一種卷簧的應(yīng)用實例，他可以減小體積。卷簧的使用不如扭簧普遍，主要原因是制作復(fù)雜，通常是找專業(yè)廠家制作，但是做少了，價格很高，廠家還賺不到錢，不愿意干，一下做多了萬一不合要求又造成很大的浪費，技術(shù)人員的面子又不好過，同時制作周期相對會長一些，因此設(shè)計人員一般盡量不使用卷簧。而多數(shù)情況下，產(chǎn)品的批量較大才值得用卷簧。</p><p style="text-indent:25px">氣囊卷簧、氣囊線圈、氣囊游絲這三個其實是一個件,只不過是叫法不同。用來連接主氣囊（方向盤上那個）與氣囊線束，其實就是一段線束。因為主氣囊要隨方向盤轉(zhuǎn)動，（可以想像成一根有一定長度的線束，纏繞在方向盤轉(zhuǎn)向軸上，在隨方向盤轉(zhuǎn)動時可以適時的反向松開或者繞的更緊，但它也是有極限的，要保證方向盤往左or右打死時，線束不能被拉斷,喇叭線也在其中）所以連接線束要留有余量，要保證方向盤向一側(cè)轉(zhuǎn)到極限位置而不被拉斷。這一點在安裝時是特別需注意的，盡量讓其保證在中間位置。碟形彈簧是用金屬板料或鍛壓坯料而成的截錐形截面的墊圈式彈簧。</p><div

style="text-indent:25px">氣囊卷簧是什么？氣囊卷簧，所屬大類為安全氣囊。安全氣囊系統(tǒng)是一種被動安全性（見汽車安全性能）的保護(hù)系統(tǒng)，它與座椅安全帶配合使用，可以為乘員提供有效的防撞保護(hù)。在汽車相撞時，汽車安全氣囊可使頭部受傷率減少25%，面部受傷率減少8 0%左右。卷簧，能夠在狹小的空間里持續(xù)提供較大的恢復(fù)力。能夠在機(jī)械部件一次行程完成后，將部件回復(fù)原位，以準(zhǔn)備下次行程。目前普遍應(yīng)用于園林工具啟動器，吸塵器等收線部件。卷簧一般是在不用電能的情況下，作為微小型機(jī)械的動力來使用，比如機(jī)械鐘表的走時動力和報時系統(tǒng)的動力；機(jī)械留聲機(jī)唱片轉(zhuǎn)動的動力；機(jī)械式八音盒；自動演奏鋼琴；上弦類玩具的動力等等。彈簧的伸長與所受之外力成正比，作用力的大小或物體重力可從彈簧秤的指針指示的外殼上的標(biāo)度數(shù)值直接讀出。嘉興小彈簧大概多少錢</p><p
