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，使用壽命長，免維護(hu)，耐高(gao)溫(wen)，耐酸堿防腐蝕(shi)(shi)，適用于高(gao)溫(wen)高(gao)速及(ji)有腐蝕(shi)(shi)工(gong)況環境的軸系(xi)傳動。

膜(mo)片(pian)型(xing)聯(lian)軸(zhou)器能補償主動(dong)(dong)機(ji)與從(cong)動(dong)(dong)機(ji)之間由于制造(zao)誤差、安裝(zhuang)誤差、承載變形以(yi)及溫升變化的(de)(de)影響等所引起的(de)(de)軸(zhou)向、徑向和角向偏移。膜(mo)片(pian)彈性聯(lian)軸(zhou)器屬金屬彈性元件撓性聯(lian)軸(zhou)器，其(qi)依靠金屬聯(lian)軸(zhou)器膜(mo)片(pian)來聯(lian)接主、從(cong)動(dong)(dong)機(ji)傳遞(di)扭矩(ju)，具有(you)彈性減振(zhen)、無噪聲、不需潤滑(hua)的(de)(de)優(you)點。

膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)(pian)聯軸(zhou)器(qi)(qi)至少由(you)一(yi)個(ge)(ge)(ge)(ge)膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)(pian)和兩個(ge)(ge)(ge)(ge)軸(zhou)套組(zu)成。膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)(pian)被(bei)用(yong)銷釘(ding)緊固在軸(zhou)套上一(yi)般(ban)不會松動或引(yin)起(qi)膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)(pian)和軸(zhou)套之(zhi)(zhi)間的(de)(de)(de)反沖。有一(yi)些(xie)生產商提(ti)供兩個(ge)(ge)(ge)(ge)膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)(pian)的(de)(de)(de)，也有提(ti)供三個(ge)(ge)(ge)(ge)膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)(pian)的(de)(de)(de)，中(zhong)間有一(yi)個(ge)(ge)(ge)(ge)或兩個(ge)(ge)(ge)(ge)剛性元(yuan)件，兩邊 再連在軸(zhou)套上。單膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)(pian)聯軸(zhou)器(qi)(qi)和雙(shuang)(shuang)膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)(pian)聯軸(zhou)器(qi)(qi)的(de)(de)(de)不同之(zhi)(zhi)處是處理各種偏(pian)(pian)差能力的(de)(de)(de)不同，鑒于其(qi)需要膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)(pian)能復雜的(de)(de)(de)彎曲，所以單膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)(pian)聯軸(zhou)器(qi)(qi)不太適應(ying)偏(pian)(pian)心。而雙(shuang)(shuang)膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)(pian)聯軸(zhou)器(qi)(qi)可以同時曲向不同的(de)(de)(de)方向，以此來補償偏(pian)(pian)心。
