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(jin)湊，傳(chuan)遞扭矩大(da)，使用壽命長，免維護，耐高溫，耐酸堿防腐(fu)蝕，適用于高溫高速及有腐(fu)蝕工況環境的軸系(xi)傳(chuan)動(dong)。

膜片(pian)型聯(lian)(lian)軸(zhou)器能(neng)補償主(zhu)動機(ji)與(yu)從動機(ji)之間由于制造(zao)誤差、安裝(zhuang)誤差、承載變形以及溫升變化的影響等所引起(qi)的軸(zhou)向、徑(jing)向和角向偏移。膜片(pian)彈性(xing)(xing)聯(lian)(lian)軸(zhou)器屬(shu)金屬(shu)彈性(xing)(xing)元件撓性(xing)(xing)聯(lian)(lian)軸(zhou)器，其依靠金屬(shu)聯(lian)(lian)軸(zhou)器膜片(pian)來(lai)聯(lian)(lian)接主(zhu)、從動機(ji)傳遞扭矩，具有彈性(xing)(xing)減振、無(wu)噪聲、不需潤滑的優點。
