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(di)扭矩大，使用(yong)壽命長，免維護，耐(nai)高(gao)溫(wen)，耐(nai)酸(suan)堿防腐(fu)蝕，適用(yong)于(yu)高(gao)溫(wen)高(gao)速及有(you)腐(fu)蝕工(gong)況環境的軸系傳動。

膜片(pian)型(xing)聯軸(zhou)(zhou)器能補償主動機與從(cong)動機之間由(you)于制造(zao)誤(wu)差、安裝誤(wu)差、承載(zai)變(bian)形以及溫升變(bian)化的(de)(de)影響(xiang)等所引起的(de)(de)軸(zhou)(zhou)向(xiang)、徑向(xiang)和角向(xiang)偏移。膜片(pian)彈(dan)性聯軸(zhou)(zhou)器屬金屬彈(dan)性元件撓性聯軸(zhou)(zhou)器，其依靠(kao)金屬聯軸(zhou)(zhou)器膜片(pian)來聯接主、從(cong)動機傳遞(di)扭矩(ju)，具有彈(dan)性減(jian)振(zhen)、無(wu)噪聲、不需潤滑的(de)(de)優點(dian)。
