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(chuan)遞扭矩大，使(shi)用壽命長，免維護，耐高(gao)溫，耐酸堿防腐蝕(shi)，適(shi)用于(yu)高(gao)溫高(gao)速及有腐蝕(shi)工(gong)況環境的軸系(xi)傳(chuan)動。

膜(mo)(mo)片(pian)型聯(lian)軸(zhou)器能補償主動機與從動機之間由(you)于制造誤(wu)差、安(an)裝誤(wu)差、承載變(bian)形以及溫升變(bian)化的影(ying)響(xiang)等所引起的軸(zhou)向、徑向和角(jiao)向偏移。膜(mo)(mo)片(pian)彈(dan)性(xing)聯(lian)軸(zhou)器屬金(jin)屬彈(dan)性(xing)元件撓性(xing)聯(lian)軸(zhou)器，其依(yi)靠金(jin)屬聯(lian)軸(zhou)器膜(mo)(mo)片(pian)來聯(lian)接主、從動機傳(chuan)遞扭矩，具有彈(dan)性(xing)減振、無噪聲、不需潤滑(hua)的優點。

膜片(pian)(pian)(pian)(pian)聯(lian)(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)至少由(you)一個(ge)(ge)(ge)(ge)膜片(pian)(pian)(pian)(pian)和兩個(ge)(ge)(ge)(ge)軸(zhou)(zhou)(zhou)套(tao)組(zu)成(cheng)。膜片(pian)(pian)(pian)(pian)被用(yong)銷釘緊固在軸(zhou)(zhou)(zhou)套(tao)上一般不(bu)會松動或引起膜片(pian)(pian)(pian)(pian)和軸(zhou)(zhou)(zhou)套(tao)之間的(de)(de)反沖。有一些生產商(shang)提(ti)供兩個(ge)(ge)(ge)(ge)膜片(pian)(pian)(pian)(pian)的(de)(de)，也有提(ti)供三(san)個(ge)(ge)(ge)(ge)膜片(pian)(pian)(pian)(pian)的(de)(de)，中間有一個(ge)(ge)(ge)(ge)或兩個(ge)(ge)(ge)(ge)剛性元件，兩邊 再連(lian)在軸(zhou)(zhou)(zhou)套(tao)上。單膜片(pian)(pian)(pian)(pian)聯(lian)(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)和雙(shuang)(shuang)膜片(pian)(pian)(pian)(pian)聯(lian)(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)的(de)(de)不(bu)同(tong)之處是(shi)處理各(ge)種偏差(cha)能(neng)力的(de)(de)不(bu)同(tong)，鑒(jian)于其需(xu)要(yao)膜片(pian)(pian)(pian)(pian)能(neng)復雜(za)的(de)(de)彎曲，所以單膜片(pian)(pian)(pian)(pian)聯(lian)(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)不(bu)太適應偏心。而雙(shuang)(shuang)膜片(pian)(pian)(pian)(pian)聯(lian)(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)可以同(tong)時曲向不(bu)同(tong)的(de)(de)方向，以此來(lai)補(bu)償偏心。
