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(da)，使用壽命長，免維護，耐(nai)高溫(wen)，耐(nai)酸堿(jian)防腐(fu)(fu)蝕，適用于高溫(wen)高速及有腐(fu)(fu)蝕工況環境的軸系傳動。

膜片(pian)型聯(lian)軸(zhou)(zhou)器(qi)能補償主動機與從動機之間由于制(zhi)造(zao)誤差(cha)、安(an)裝誤差(cha)、承載(zai)變形以及溫升變化(hua)的影響等所引起的軸(zhou)(zhou)向(xiang)(xiang)、徑向(xiang)(xiang)和(he)角(jiao)向(xiang)(xiang)偏移。膜片(pian)彈(dan)性聯(lian)軸(zhou)(zhou)器(qi)屬(shu)金(jin)屬(shu)彈(dan)性元件撓性聯(lian)軸(zhou)(zhou)器(qi)，其(qi)依靠金(jin)屬(shu)聯(lian)軸(zhou)(zhou)器(qi)膜片(pian)來(lai)聯(lian)接主、從動機傳遞扭矩，具有彈(dan)性減振、無噪聲、不需潤(run)滑的優點(dian)。
