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(chuan)遞(di)扭矩大，使用壽命長，免維護，耐高溫(wen)，耐酸堿防(fang)腐蝕(shi)(shi)，適用于高溫(wen)高速及有腐蝕(shi)(shi)工況(kuang)環境的軸(zhou)系傳(chuan)動(dong)。

膜(mo)(mo)片(pian)型聯(lian)(lian)軸(zhou)器(qi)能補(bu)償主動機與從(cong)動機之間(jian)由于制(zhi)造誤(wu)差、安裝(zhuang)誤(wu)差、承(cheng)載(zai)變(bian)形以及溫(wen)升變(bian)化的影響等所引(yin)起(qi)的軸(zhou)向(xiang)、徑向(xiang)和角向(xiang)偏移。膜(mo)(mo)片(pian)彈(dan)性(xing)聯(lian)(lian)軸(zhou)器(qi)屬(shu)金屬(shu)彈(dan)性(xing)元件撓性(xing)聯(lian)(lian)軸(zhou)器(qi)，其依靠(kao)金屬(shu)聯(lian)(lian)軸(zhou)器(qi)膜(mo)(mo)片(pian)來聯(lian)(lian)接主、從(cong)動機傳遞扭矩，具有彈(dan)性(xing)減振、無噪(zao)聲、不需潤滑的優點(dian)。
