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，耐高溫，耐酸(suan)堿防(fang)腐(fu)(fu)蝕，適用于高溫高速及有腐(fu)(fu)蝕工況環境的軸系傳動(dong)。

膜(mo)片型聯(lian)軸器(qi)能補償主動機與從(cong)動機之間由于制(zhi)造誤差、安(an)裝(zhuang)誤差、承載變形以及溫升變化的(de)影響(xiang)等所引起的(de)軸向(xiang)、徑向(xiang)和角向(xiang)偏移。膜(mo)片彈(dan)性聯(lian)軸器(qi)屬金屬彈(dan)性元件撓性聯(lian)軸器(qi)，其依靠金屬聯(lian)軸器(qi)膜(mo)片來聯(lian)接主、從(cong)動機傳(chuan)遞扭矩，具有彈(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)(lian)軸(zhou)(zhou)器至少由(you)一(yi)(yi)(yi)個(ge)膜(mo)(mo)片(pian)(pian)(pian)(pian)和兩個(ge)軸(zhou)(zhou)套(tao)組成(cheng)。膜(mo)(mo)片(pian)(pian)(pian)(pian)被用銷釘緊(jin)固在軸(zhou)(zhou)套(tao)上一(yi)(yi)(yi)般不(bu)(bu)會松(song)動或引起膜(mo)(mo)片(pian)(pian)(pian)(pian)和軸(zhou)(zhou)套(tao)之間的反沖。有(you)一(yi)(yi)(yi)些生產商提供(gong)兩個(ge)膜(mo)(mo)片(pian)(pian)(pian)(pian)的，也有(you)提供(gong)三個(ge)膜(mo)(mo)片(pian)(pian)(pian)(pian)的，中間有(you)一(yi)(yi)(yi)個(ge)或兩個(ge)剛性元(yuan)件，兩邊 再(zai)連在軸(zhou)(zhou)套(tao)上。單(dan)膜(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)(lian)軸(zhou)(zhou)器和雙(shuang)膜(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)(lian)軸(zhou)(zhou)器的不(bu)(bu)同(tong)之處是(shi)處理各種偏(pian)差(cha)能力的不(bu)(bu)同(tong)，鑒于其需要膜(mo)(mo)片(pian)(pian)(pian)(pian)能復雜的彎曲(qu)，所以(yi)單(dan)膜(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)(lian)軸(zhou)(zhou)器不(bu)(bu)太適(shi)應偏(pian)心(xin)。而雙(shuang)膜(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)(lian)軸(zhou)(zhou)器可(ke)以(yi)同(tong)時曲(qu)向不(bu)(bu)同(tong)的方向，以(yi)此來補償偏(pian)心(xin)。
