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(gou)緊湊，傳遞(di)扭矩大(da)，使用壽命長(chang)，免維護，耐高(gao)溫，耐酸(suan)堿防腐(fu)蝕(shi)，適(shi)用于高(gao)溫高(gao)速及有腐(fu)蝕(shi)工況環境的軸系傳動(dong)。

膜片型聯(lian)(lian)軸器(qi)(qi)能補償主(zhu)動(dong)(dong)機與從(cong)動(dong)(dong)機之間由(you)于制造誤差、安裝誤差、承載(zai)變形以(yi)及溫升變化的影響等(deng)所引起的軸向(xiang)、徑向(xiang)和角向(xiang)偏移。膜片彈(dan)(dan)性(xing)聯(lian)(lian)軸器(qi)(qi)屬(shu)金屬(shu)彈(dan)(dan)性(xing)元件撓性(xing)聯(lian)(lian)軸器(qi)(qi)，其依靠金屬(shu)聯(lian)(lian)軸器(qi)(qi)膜片來聯(lian)(lian)接(jie)主(zhu)、從(cong)動(dong)(dong)機傳遞扭矩，具有(you)彈(dan)(dan)性(xing)減(jian)振(zhen)、無(wu)噪聲(sheng)、不需(xu)潤滑(hua)的優點。
