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(niu)矩大，使用壽命長，免(mian)維護，耐高(gao)溫，耐酸堿防腐(fu)蝕，適用于高(gao)溫高(gao)速及有腐(fu)蝕工況環境的軸系傳(chuan)動。

膜(mo)(mo)片(pian)(pian)型聯(lian)(lian)(lian)軸(zhou)器(qi)(qi)(qi)能補(bu)償主動機(ji)與(yu)從動機(ji)之間由于制造(zao)誤(wu)差、安(an)裝誤(wu)差、承載(zai)變形以及溫升變化的(de)影響等所引(yin)起的(de)軸(zhou)向、徑向和角向偏移。膜(mo)(mo)片(pian)(pian)彈(dan)性聯(lian)(lian)(lian)軸(zhou)器(qi)(qi)(qi)屬金(jin)屬彈(dan)性元件(jian)撓性聯(lian)(lian)(lian)軸(zhou)器(qi)(qi)(qi)，其依靠金(jin)屬聯(lian)(lian)(lian)軸(zhou)器(qi)(qi)(qi)膜(mo)(mo)片(pian)(pian)來聯(lian)(lian)(lian)接(jie)主、從動機(ji)傳(chuan)遞扭矩，具有彈(dan)性減振、無噪聲、不需(xu)潤(run)滑的(de)優點。
