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，使用壽(shou)命長(chang)，免維護(hu)，耐高(gao)溫，耐酸堿防腐蝕(shi)(shi)，適(shi)用于高(gao)溫高(gao)速及(ji)有腐蝕(shi)(shi)工況環境的(de)軸系傳(chuan)動。

膜片(pian)型聯(lian)(lian)(lian)軸(zhou)器(qi)能補償(chang)主(zhu)動機與從(cong)動機之間由(you)于制造誤差、安裝誤差、承載變(bian)形以及溫升變(bian)化(hua)的影響等所引起的軸(zhou)向、徑向和角向偏移。膜片(pian)彈(dan)(dan)性(xing)聯(lian)(lian)(lian)軸(zhou)器(qi)屬金屬彈(dan)(dan)性(xing)元(yuan)件撓性(xing)聯(lian)(lian)(lian)軸(zhou)器(qi)，其依(yi)靠金屬聯(lian)(lian)(lian)軸(zhou)器(qi)膜片(pian)來聯(lian)(lian)(lian)接主(zhu)、從(cong)動機傳(chuan)遞扭矩，具有彈(dan)(dan)性(xing)減振、無噪聲(sheng)、不需潤滑的優點。

膜片(pian)(pian)(pian)聯(lian)軸(zhou)器(qi)至少(shao)由一(yi)個(ge)(ge)(ge)膜片(pian)(pian)(pian)和兩個(ge)(ge)(ge)軸(zhou)套組成。膜片(pian)(pian)(pian)被(bei)用(yong)銷釘緊固在軸(zhou)套上一(yi)般不(bu)會松動或引(yin)起膜片(pian)(pian)(pian)和軸(zhou)套之間的(de)反沖。有一(yi)些(xie)生產商(shang)提供(gong)(gong)兩個(ge)(ge)(ge)膜片(pian)(pian)(pian)的(de)，也有提供(gong)(gong)三個(ge)(ge)(ge)膜片(pian)(pian)(pian)的(de)，中間有一(yi)個(ge)(ge)(ge)或兩個(ge)(ge)(ge)剛性元件，兩邊 再(zai)連在軸(zhou)套上。單膜片(pian)(pian)(pian)聯(lian)軸(zhou)器(qi)和雙(shuang)膜片(pian)(pian)(pian)聯(lian)軸(zhou)器(qi)的(de)不(bu)同(tong)之處是處理各種偏(pian)(pian)差能力的(de)不(bu)同(tong)，鑒(jian)于其需要膜片(pian)(pian)(pian)能復雜的(de)彎曲，所以(yi)單膜片(pian)(pian)(pian)聯(lian)軸(zhou)器(qi)不(bu)太適應偏(pian)(pian)心。而(er)雙(shuang)膜片(pian)(pian)(pian)聯(lian)軸(zhou)器(qi)可以(yi)同(tong)時曲向不(bu)同(tong)的(de)方向，以(yi)此(ci)來補(bu)償偏(pian)(pian)心。
