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)構緊湊，傳遞扭矩(ju)大，使(shi)用(yong)壽命(ming)長，免維護，耐高(gao)溫，耐酸堿防(fang)腐蝕，適用(yong)于高(gao)溫高(gao)速(su)及有腐蝕工況環境的軸系傳動。

膜片(pian)型聯(lian)軸器(qi)能(neng)補(bu)償主動(dong)(dong)機(ji)(ji)與從動(dong)(dong)機(ji)(ji)之(zhi)間由于(yu)制造誤差、安裝誤差、承載變形以及溫升變化的影響等所引起的軸向、徑向和角向偏移(yi)。膜片(pian)彈性(xing)(xing)聯(lian)軸器(qi)屬金(jin)屬彈性(xing)(xing)元件撓性(xing)(xing)聯(lian)軸器(qi)，其(qi)依靠(kao)金(jin)屬聯(lian)軸器(qi)膜片(pian)來聯(lian)接主、從動(dong)(dong)機(ji)(ji)傳遞扭矩，具有彈性(xing)(xing)減(jian)振、無(wu)噪聲、不(bu)需潤滑的優點。
