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，傳遞扭矩大(da)，使用壽(shou)命長，免維護，耐(nai)高(gao)溫(wen)，耐(nai)酸(suan)堿防(fang)腐蝕(shi)，適用于高(gao)溫(wen)高(gao)速及有腐蝕(shi)工(gong)況環境的軸(zhou)系(xi)傳動(dong)。

膜(mo)片(pian)型聯(lian)(lian)軸(zhou)器能補(bu)償(chang)主(zhu)動機(ji)與從動機(ji)之間由(you)于(yu)制造誤(wu)差、安裝(zhuang)誤(wu)差、承載變形以及溫升變化的(de)影響等所(suo)引起的(de)軸(zhou)向、徑向和角向偏移。膜(mo)片(pian)彈性(xing)聯(lian)(lian)軸(zhou)器屬(shu)金屬(shu)彈性(xing)元(yuan)件撓性(xing)聯(lian)(lian)軸(zhou)器，其依(yi)靠金屬(shu)聯(lian)(lian)軸(zhou)器膜(mo)片(pian)來聯(lian)(lian)接主(zhu)、從動機(ji)傳遞扭矩，具有彈性(xing)減振、無噪聲(sheng)、不需潤滑的(de)優點。
