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(cou)，傳遞扭(niu)矩(ju)大，使用(yong)(yong)壽(shou)命長(chang)，免維(wei)護，耐(nai)(nai)高(gao)溫，耐(nai)(nai)酸堿(jian)防腐(fu)蝕(shi)，適用(yong)(yong)于高(gao)溫高(gao)速及(ji)有腐(fu)蝕(shi)工況(kuang)環(huan)境的軸系傳動。

膜片(pian)型聯(lian)(lian)軸(zhou)器(qi)能補償主動機(ji)與從(cong)(cong)動機(ji)之間(jian)由(you)于制造誤(wu)差(cha)(cha)、安裝誤(wu)差(cha)(cha)、承載變形以(yi)及溫升變化的(de)影響等(deng)所引起的(de)軸(zhou)向、徑(jing)向和角向偏移。膜片(pian)彈(dan)性(xing)(xing)聯(lian)(lian)軸(zhou)器(qi)屬金屬彈(dan)性(xing)(xing)元(yuan)件撓(nao)性(xing)(xing)聯(lian)(lian)軸(zhou)器(qi)，其依靠金屬聯(lian)(lian)軸(zhou)器(qi)膜片(pian)來(lai)聯(lian)(lian)接主、從(cong)(cong)動機(ji)傳遞扭矩(ju)，具有(you)彈(dan)性(xing)(xing)減振、無(wu)噪聲、不需潤滑(hua)的(de)優(you)點。
