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(niu)矩大，使用壽命(ming)長(chang)，免(mian)維護，耐高(gao)溫，耐酸(suan)堿防腐蝕，適用于高(gao)溫高(gao)速及(ji)有腐蝕工(gong)況(kuang)環境的軸系(xi)傳動。

膜(mo)片(pian)(pian)型聯軸(zhou)器(qi)(qi)能補(bu)償主(zhu)動(dong)(dong)(dong)機與從(cong)動(dong)(dong)(dong)機之間由于制造誤差、安裝誤差、承載變形以及溫升變化的影響(xiang)等所引起的軸(zhou)向(xiang)、徑向(xiang)和(he)角向(xiang)偏移。膜(mo)片(pian)(pian)彈性(xing)(xing)聯軸(zhou)器(qi)(qi)屬(shu)金(jin)(jin)屬(shu)彈性(xing)(xing)元件撓性(xing)(xing)聯軸(zhou)器(qi)(qi)，其依靠金(jin)(jin)屬(shu)聯軸(zhou)器(qi)(qi)膜(mo)片(pian)(pian)來聯接主(zhu)、從(cong)動(dong)(dong)(dong)機傳遞扭矩(ju)，具有彈性(xing)(xing)減振、無噪聲、不需潤滑的優(you)點(dian)。
