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(chuan)遞扭矩大(da)，使(shi)用壽命(ming)長，免維(wei)護，耐高溫(wen)，耐酸堿(jian)防腐蝕，適用于(yu)高溫(wen)高速及有腐蝕工況(kuang)環(huan)境的軸系傳(chuan)動。

膜片(pian)型聯(lian)(lian)軸(zhou)器能(neng)補償主動機(ji)(ji)與從(cong)動機(ji)(ji)之間由(you)于制造誤(wu)差(cha)、安裝誤(wu)差(cha)、承載變(bian)形(xing)以(yi)及溫升變(bian)化的(de)影響等所(suo)引起的(de)軸(zhou)向、徑向和角向偏移。膜片(pian)彈性(xing)(xing)聯(lian)(lian)軸(zhou)器屬(shu)金屬(shu)彈性(xing)(xing)元件(jian)撓性(xing)(xing)聯(lian)(lian)軸(zhou)器，其依靠金屬(shu)聯(lian)(lian)軸(zhou)器膜片(pian)來聯(lian)(lian)接主、從(cong)動機(ji)(ji)傳遞(di)扭(niu)矩(ju)，具(ju)有彈性(xing)(xing)減振、無噪聲(sheng)、不需潤滑的(de)優點。
