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)構緊(jin)湊，傳(chuan)遞(di)扭矩大，使用壽命長(chang)，免維護，耐高溫，耐酸堿防腐蝕(shi)，適用于高溫高速及(ji)有(you)腐蝕(shi)工況(kuang)環境(jing)的軸系傳(chuan)動。

膜片型聯(lian)軸器能補(bu)償(chang)主(zhu)動機(ji)與從動機(ji)之(zhi)間由于制(zhi)造誤差、安裝誤差、承載變(bian)形以及溫(wen)升變(bian)化(hua)的影響等所引(yin)起(qi)的軸向(xiang)、徑向(xiang)和角向(xiang)偏移。膜片彈(dan)性(xing)(xing)聯(lian)軸器屬金屬彈(dan)性(xing)(xing)元(yuan)件撓性(xing)(xing)聯(lian)軸器，其依靠金屬聯(lian)軸器膜片來聯(lian)接主(zhu)、從動機(ji)傳遞(di)扭矩(ju)，具有彈(dan)性(xing)(xing)減振、無噪(zao)聲、不需潤滑(hua)的優點。

膜(mo)(mo)片(pian)(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)器至少由一(yi)(yi)個膜(mo)(mo)片(pian)(pian)(pian)和兩(liang)(liang)個軸(zhou)(zhou)套(tao)組成。膜(mo)(mo)片(pian)(pian)(pian)被(bei)用(yong)銷釘緊固在軸(zhou)(zhou)套(tao)上一(yi)(yi)般不(bu)(bu)會松動或引起膜(mo)(mo)片(pian)(pian)(pian)和軸(zhou)(zhou)套(tao)之間的(de)(de)(de)(de)反沖。有(you)一(yi)(yi)些生產商提(ti)供兩(liang)(liang)個膜(mo)(mo)片(pian)(pian)(pian)的(de)(de)(de)(de)，也(ye)有(you)提(ti)供三個膜(mo)(mo)片(pian)(pian)(pian)的(de)(de)(de)(de)，中(zhong)間有(you)一(yi)(yi)個或兩(liang)(liang)個剛(gang)性元件，兩(liang)(liang)邊 再連在軸(zhou)(zhou)套(tao)上。單膜(mo)(mo)片(pian)(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)器和雙膜(mo)(mo)片(pian)(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)器的(de)(de)(de)(de)不(bu)(bu)同(tong)(tong)之處(chu)是處(chu)理各種偏(pian)(pian)差能力的(de)(de)(de)(de)不(bu)(bu)同(tong)(tong)，鑒于(yu)其(qi)需要膜(mo)(mo)片(pian)(pian)(pian)能復(fu)雜的(de)(de)(de)(de)彎曲，所(suo)以單膜(mo)(mo)片(pian)(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)器不(bu)(bu)太(tai)適應偏(pian)(pian)心。而雙膜(mo)(mo)片(pian)(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)器可(ke)以同(tong)(tong)時曲向不(bu)(bu)同(tong)(tong)的(de)(de)(de)(de)方(fang)向，以此來補償(chang)偏(pian)(pian)心。
