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，傳遞扭矩大(da)，使用壽命長，免維護，耐高(gao)溫，耐酸堿防腐蝕，適用于高(gao)溫高(gao)速(su)及(ji)有腐蝕工況環(huan)境的軸系傳動(dong)。

膜片型聯(lian)(lian)軸(zhou)器(qi)能補償主(zhu)動(dong)機(ji)與(yu)從動(dong)機(ji)之間由(you)于制(zhi)造誤差、安裝誤差、承載變形(xing)以(yi)及溫升變化的影響(xiang)等所引起的軸(zhou)向、徑向和(he)角向偏移(yi)。膜片彈(dan)性(xing)聯(lian)(lian)軸(zhou)器(qi)屬金(jin)屬彈(dan)性(xing)元件撓性(xing)聯(lian)(lian)軸(zhou)器(qi)，其依靠金(jin)屬聯(lian)(lian)軸(zhou)器(qi)膜片來聯(lian)(lian)接主(zhu)、從動(dong)機(ji)傳遞扭矩，具有彈(dan)性(xing)減振、無噪聲、不(bu)需潤滑(hua)的優點。
