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(gou)緊湊，傳(chuan)(chuan)遞扭矩大，使用壽命(ming)長，免維(wei)護，耐(nai)高(gao)溫，耐(nai)酸堿防腐(fu)蝕(shi)，適用于(yu)高(gao)溫高(gao)速及有腐(fu)蝕(shi)工況環境的軸系傳(chuan)(chuan)動。

膜片(pian)(pian)(pian)型聯(lian)(lian)(lian)軸器(qi)能補償主動(dong)機(ji)與從(cong)動(dong)機(ji)之間(jian)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(de)影(ying)響等所引起的(de)軸向、徑向和(he)角向偏移。膜片(pian)(pian)(pian)彈(dan)性(xing)聯(lian)(lian)(lian)軸器(qi)屬金屬彈(dan)性(xing)元件撓性(xing)聯(lian)(lian)(lian)軸器(qi)，其依靠金屬聯(lian)(lian)(lian)軸器(qi)膜片(pian)(pian)(pian)來聯(lian)(lian)(lian)接主、從(cong)動(dong)機(ji)傳(chuan)遞扭矩，具有彈(dan)性(xing)減(jian)振、無噪聲、不需潤滑的(de)優點。

膜片(pian)(pian)(pian)(pian)聯軸(zhou)器至少(shao)由一個(ge)膜片(pian)(pian)(pian)(pian)和兩(liang)個(ge)軸(zhou)套(tao)組成(cheng)。膜片(pian)(pian)(pian)(pian)被用銷釘緊固在(zai)軸(zhou)套(tao)上一般不(bu)(bu)會松動或(huo)引起膜片(pian)(pian)(pian)(pian)和軸(zhou)套(tao)之間的反沖。有(you)一些(xie)生產(chan)商提供兩(liang)個(ge)膜片(pian)(pian)(pian)(pian)的，也有(you)提供三個(ge)膜片(pian)(pian)(pian)(pian)的，中間有(you)一個(ge)或(huo)兩(liang)個(ge)剛性元件，兩(liang)邊 再連(lian)在(zai)軸(zhou)套(tao)上。單(dan)膜片(pian)(pian)(pian)(pian)聯軸(zhou)器和雙(shuang)(shuang)膜片(pian)(pian)(pian)(pian)聯軸(zhou)器的不(bu)(bu)同(tong)之處是處理(li)各種偏差能(neng)力的不(bu)(bu)同(tong)，鑒于其需(xu)要膜片(pian)(pian)(pian)(pian)能(neng)復雜(za)的彎曲(qu)，所(suo)以(yi)單(dan)膜片(pian)(pian)(pian)(pian)聯軸(zhou)器不(bu)(bu)太適應偏心。而雙(shuang)(shuang)膜片(pian)(pian)(pian)(pian)聯軸(zhou)器可以(yi)同(tong)時曲(qu)向不(bu)(bu)同(tong)的方向，以(yi)此來補償偏心。
