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(gou)緊湊，傳(chuan)遞扭矩(ju)大，使用(yong)壽命(ming)長，免維護，耐高(gao)溫，耐酸堿(jian)防腐(fu)蝕(shi)，適用(yong)于高(gao)溫高(gao)速及有腐(fu)蝕(shi)工況環境的軸系傳(chuan)動。

膜(mo)片(pian)型聯(lian)軸器(qi)(qi)能補償主動機(ji)與從(cong)動機(ji)之(zhi)間(jian)由于(yu)制(zhi)造誤差、安裝誤差、承載(zai)變形以及(ji)溫升變化的影響(xiang)等所引起(qi)的軸向、徑向和角向偏移。膜(mo)片(pian)彈(dan)性(xing)(xing)聯(lian)軸器(qi)(qi)屬金屬彈(dan)性(xing)(xing)元件撓性(xing)(xing)聯(lian)軸器(qi)(qi)，其依靠(kao)金屬聯(lian)軸器(qi)(qi)膜(mo)片(pian)來聯(lian)接主、從(cong)動機(ji)傳遞扭矩(ju)，具(ju)有彈(dan)性(xing)(xing)減振、無噪聲、不需(xu)潤滑的優(you)點(dian)。
