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，傳遞扭矩大，使用壽命長，免(mian)維護，耐高(gao)(gao)溫，耐酸堿防腐蝕，適用于高(gao)(gao)溫高(gao)(gao)速及有(you)腐蝕工況(kuang)環境的軸系傳動。

膜片(pian)型聯(lian)(lian)(lian)軸器(qi)能補(bu)償主動機(ji)與從動機(ji)之間(jian)由于制造誤差、安裝誤差、承載(zai)變形(xing)以(yi)及(ji)溫升變化的影響等所引起的軸向、徑(jing)向和(he)角向偏(pian)移。膜片(pian)彈(dan)性(xing)聯(lian)(lian)(lian)軸器(qi)屬(shu)(shu)金(jin)屬(shu)(shu)彈(dan)性(xing)元件撓(nao)性(xing)聯(lian)(lian)(lian)軸器(qi)，其依靠(kao)金(jin)屬(shu)(shu)聯(lian)(lian)(lian)軸器(qi)膜片(pian)來聯(lian)(lian)(lian)接(jie)主、從動機(ji)傳遞扭矩，具(ju)有彈(dan)性(xing)減振、無(wu)噪(zao)聲(sheng)、不(bu)需(xu)潤滑(hua)的優點(dian)。
