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(jie)構緊(jin)湊，傳(chuan)遞扭矩大，使用(yong)壽命長，免維護，耐高(gao)(gao)溫，耐酸堿防腐蝕，適用(yong)于(yu)高(gao)(gao)溫高(gao)(gao)速及有腐蝕工況環境的軸系傳(chuan)動。

膜片(pian)型聯軸(zhou)器(qi)(qi)能補償主動機與從動機之間(jian)由于制造誤差(cha)(cha)、安(an)裝誤差(cha)(cha)、承(cheng)載變(bian)形以及溫升變(bian)化的影響等(deng)所引起的軸(zhou)向(xiang)、徑向(xiang)和角向(xiang)偏(pian)移。膜片(pian)彈性(xing)聯軸(zhou)器(qi)(qi)屬金(jin)屬彈性(xing)元件撓性(xing)聯軸(zhou)器(qi)(qi)，其依靠金(jin)屬聯軸(zhou)器(qi)(qi)膜片(pian)來(lai)聯接主、從動機傳遞(di)扭矩，具有彈性(xing)減振、無噪(zao)聲、不需(xu)潤滑的優點(dian)。
