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(gou)緊湊，傳遞(di)扭矩大(da)，使用(yong)壽命長，免維(wei)護，耐高溫，耐酸堿防(fang)腐(fu)蝕(shi)(shi)，適(shi)用(yong)于高溫高速(su)及有腐(fu)蝕(shi)(shi)工況(kuang)環境的軸(zhou)系傳動。

膜片(pian)型聯(lian)軸(zhou)(zhou)器(qi)能(neng)補(bu)償主(zhu)動(dong)機(ji)與從動(dong)機(ji)之間由于制造誤(wu)差、安(an)裝誤(wu)差、承載變形以及溫升(sheng)變化的影響等所引(yin)起的軸(zhou)(zhou)向(xiang)、徑向(xiang)和角向(xiang)偏(pian)移。膜片(pian)彈(dan)性(xing)聯(lian)軸(zhou)(zhou)器(qi)屬(shu)金屬(shu)彈(dan)性(xing)元件(jian)撓性(xing)聯(lian)軸(zhou)(zhou)器(qi)，其依靠(kao)金屬(shu)聯(lian)軸(zhou)(zhou)器(qi)膜片(pian)來聯(lian)接主(zhu)、從動(dong)機(ji)傳遞(di)扭矩，具有彈(dan)性(xing)減振、無噪(zao)聲、不需潤滑的優點。
