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(chuan)遞扭(niu)矩(ju)大，使用壽命長，免維護(hu)，耐高(gao)(gao)(gao)溫(wen)，耐酸(suan)堿防(fang)腐蝕，適用于高(gao)(gao)(gao)溫(wen)高(gao)(gao)(gao)速及有腐蝕工況環境的軸系傳(chuan)動。

膜片(pian)(pian)(pian)型聯(lian)軸(zhou)器(qi)能補償主(zhu)(zhu)動(dong)機(ji)與(yu)從動(dong)機(ji)之間由于制造誤(wu)差(cha)、安裝誤(wu)差(cha)、承載變形(xing)以及溫(wen)升(sheng)變化的影響等所(suo)引起的軸(zhou)向(xiang)、徑(jing)向(xiang)和角向(xiang)偏移(yi)。膜片(pian)(pian)(pian)彈性(xing)聯(lian)軸(zhou)器(qi)屬金(jin)屬彈性(xing)元件(jian)撓性(xing)聯(lian)軸(zhou)器(qi)，其依靠金(jin)屬聯(lian)軸(zhou)器(qi)膜片(pian)(pian)(pian)來聯(lian)接主(zhu)(zhu)、從動(dong)機(ji)傳(chuan)遞扭矩，具(ju)有彈性(xing)減振、無(wu)噪聲、不需潤滑的優點。

膜(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)(lian)軸器至少由一個膜(mo)(mo)片(pian)(pian)(pian)(pian)和兩(liang)個軸套組成。膜(mo)(mo)片(pian)(pian)(pian)(pian)被(bei)用銷釘緊固(gu)在軸套上一般不會松動或引起(qi)膜(mo)(mo)片(pian)(pian)(pian)(pian)和軸套之間的反(fan)沖。有一些(xie)生產商提供兩(liang)個膜(mo)(mo)片(pian)(pian)(pian)(pian)的，也有提供三個膜(mo)(mo)片(pian)(pian)(pian)(pian)的，中(zhong)間有一個或兩(liang)個剛性元件，兩(liang)邊 再連在軸套上。單(dan)膜(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)(lian)軸器和雙膜(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)(lian)軸器的不同之處是處理各種(zhong)偏差能(neng)力的不同，鑒(jian)于其需要膜(mo)(mo)片(pian)(pian)(pian)(pian)能(neng)復(fu)雜的彎曲，所以單(dan)膜(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)(lian)軸器不太適(shi)應(ying)偏心。而雙膜(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)(lian)軸器可(ke)以同時曲向不同的方向，以此來補償偏心。
