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(gou)緊(jin)湊，傳遞扭(niu)矩大，使用壽命長(chang)，免維護，耐高溫，耐酸堿(jian)防腐(fu)(fu)蝕(shi)，適用于高溫高速及有腐(fu)(fu)蝕(shi)工(gong)況環境的軸系傳動。

膜片型聯軸(zhou)(zhou)(zhou)(zhou)器(qi)能補(bu)償主動(dong)機與從(cong)動(dong)機之間(jian)由于制(zhi)造誤差、安裝誤差、承載(zai)變(bian)形以(yi)及溫升(sheng)變(bian)化的影(ying)響等(deng)所引起(qi)的軸(zhou)(zhou)(zhou)(zhou)向(xiang)、徑向(xiang)和角向(xiang)偏移。膜片彈(dan)性(xing)聯軸(zhou)(zhou)(zhou)(zhou)器(qi)屬(shu)(shu)金(jin)屬(shu)(shu)彈(dan)性(xing)元(yuan)件撓性(xing)聯軸(zhou)(zhou)(zhou)(zhou)器(qi)，其依靠金(jin)屬(shu)(shu)聯軸(zhou)(zhou)(zhou)(zhou)器(qi)膜片來聯接(jie)主、從(cong)動(dong)機傳遞(di)扭矩(ju)，具有(you)彈(dan)性(xing)減振、無(wu)噪聲、不需潤滑的優點。
