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(jin)湊，傳遞扭矩大，使用壽命長(chang)，免維護(hu)，耐高(gao)溫(wen)，耐酸堿防腐蝕，適用于高(gao)溫(wen)高(gao)速及有腐蝕工況(kuang)環(huan)境的軸系傳動。

膜(mo)片(pian)(pian)型聯軸器(qi)能補(bu)償(chang)主(zhu)(zhu)動機(ji)(ji)與(yu)從動機(ji)(ji)之間由于制(zhi)造誤差、安裝誤差、承載變形以及溫升變化的影響(xiang)等所(suo)引(yin)起(qi)的軸向、徑(jing)向和(he)角向偏(pian)移。膜(mo)片(pian)(pian)彈性聯軸器(qi)屬(shu)金屬(shu)彈性元件撓性聯軸器(qi)，其依靠金屬(shu)聯軸器(qi)膜(mo)片(pian)(pian)來聯接主(zhu)(zhu)、從動機(ji)(ji)傳遞扭矩，具有彈性減振、無噪聲、不需潤滑(hua)的優點(dian)。
