膜片聯軸器在傳遞扭矩的同時通過彈性膜片的的變形來補償軸向和角向的位移，是一種高性能的金屬彈性撓性聯軸器。膜片式聯軸器結構緊湊，傳遞扭矩大，使用(yong)壽命長，免維護，耐高溫，耐酸堿防腐蝕(shi)，適用(yong)于高溫高速(su)及(ji)有腐蝕(shi)工況(kuang)環境的軸系傳動。

膜片(pian)型聯(lian)(lian)(lian)軸(zhou)器能補償(chang)主動機(ji)(ji)與(yu)從動機(ji)(ji)之間由于制造(zao)誤差、安(an)裝誤差、承載變形以及(ji)溫升(sheng)變化的(de)影響等所引起的(de)軸(zhou)向、徑(jing)向和角向偏移。膜片(pian)彈(dan)(dan)性聯(lian)(lian)(lian)軸(zhou)器屬金屬彈(dan)(dan)性元件撓性聯(lian)(lian)(lian)軸(zhou)器，其依靠(kao)金屬聯(lian)(lian)(lian)軸(zhou)器膜片(pian)來(lai)聯(lian)(lian)(lian)接(jie)主、從動機(ji)(ji)傳遞扭(niu)矩，具有(you)彈(dan)(dan)性減振、無噪聲、不需潤滑的(de)優(you)點。

膜(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)軸器(qi)(qi)(qi)至少由一個(ge)(ge)膜(mo)(mo)片(pian)(pian)(pian)(pian)和(he)兩個(ge)(ge)軸套(tao)組成。膜(mo)(mo)片(pian)(pian)(pian)(pian)被(bei)用銷釘緊(jin)固在軸套(tao)上一般不(bu)(bu)會(hui)松動或(huo)引起膜(mo)(mo)片(pian)(pian)(pian)(pian)和(he)軸套(tao)之間(jian)(jian)的(de)(de)(de)反沖。有一些生(sheng)產商(shang)提供(gong)兩個(ge)(ge)膜(mo)(mo)片(pian)(pian)(pian)(pian)的(de)(de)(de)，也有提供(gong)三(san)個(ge)(ge)膜(mo)(mo)片(pian)(pian)(pian)(pian)的(de)(de)(de)，中(zhong)間(jian)(jian)有一個(ge)(ge)或(huo)兩個(ge)(ge)剛性元件，兩邊 再連在軸套(tao)上。單膜(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)軸器(qi)(qi)(qi)和(he)雙(shuang)膜(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)軸器(qi)(qi)(qi)的(de)(de)(de)不(bu)(bu)同之處是(shi)處理各種偏差(cha)能(neng)(neng)力(li)的(de)(de)(de)不(bu)(bu)同，鑒于(yu)其需要膜(mo)(mo)片(pian)(pian)(pian)(pian)能(neng)(neng)復雜(za)的(de)(de)(de)彎曲，所以(yi)單膜(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)軸器(qi)(qi)(qi)不(bu)(bu)太適(shi)應偏心。而雙(shuang)膜(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)軸器(qi)(qi)(qi)可以(yi)同時曲向(xiang)不(bu)(bu)同的(de)(de)(de)方向(xiang)，以(yi)此來補償偏心。
