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(shi)用壽命長，免維護，耐(nai)高(gao)溫(wen)，耐(nai)酸堿防腐(fu)蝕(shi)，適用于高(gao)溫(wen)高(gao)速及有(you)腐(fu)蝕(shi)工況環境的軸(zhou)系傳動。

膜片型聯(lian)(lian)(lian)軸(zhou)器(qi)能補償主(zhu)動(dong)機與從(cong)(cong)動(dong)機之間由于制造誤差、安裝誤差、承(cheng)載變形以及溫(wen)升(sheng)變化的影響等所(suo)引(yin)起的軸(zhou)向、徑向和角向偏移。膜片彈(dan)(dan)(dan)性(xing)聯(lian)(lian)(lian)軸(zhou)器(qi)屬金(jin)屬彈(dan)(dan)(dan)性(xing)元件撓(nao)性(xing)聯(lian)(lian)(lian)軸(zhou)器(qi)，其依靠(kao)金(jin)屬聯(lian)(lian)(lian)軸(zhou)器(qi)膜片來聯(lian)(lian)(lian)接主(zhu)、從(cong)(cong)動(dong)機傳遞扭矩，具有彈(dan)(dan)(dan)性(xing)減振(zhen)、無噪聲(sheng)、不需潤(run)滑的優點。
