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，傳遞扭(niu)矩大，使(shi)用壽命(ming)長，免維護(hu)，耐高溫，耐酸堿(jian)防腐蝕，適用于(yu)高溫高速及有腐蝕工況環境的軸系傳動。

膜片(pian)(pian)(pian)型聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)(qi)能補(bu)償(chang)主(zhu)動(dong)機與從動(dong)機之(zhi)間由于制造(zao)誤(wu)差、安裝(zhuang)誤(wu)差、承(cheng)載(zai)變形以及溫升變化的影(ying)響等所引起(qi)的軸(zhou)(zhou)向、徑向和角(jiao)向偏移。膜片(pian)(pian)(pian)彈(dan)性(xing)聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)(qi)屬金(jin)屬彈(dan)性(xing)元件撓性(xing)聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)(qi)，其依靠金(jin)屬聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)(qi)膜片(pian)(pian)(pian)來聯(lian)(lian)(lian)接(jie)主(zhu)、從動(dong)機傳遞扭矩，具有彈(dan)性(xing)減振、無噪聲、不需潤滑的優點。

膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)器(qi)至少(shao)由一(yi)個膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)和兩個軸(zhou)(zhou)套(tao)組成。膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)被用銷釘緊固(gu)在(zai)軸(zhou)(zhou)套(tao)上(shang)一(yi)般不(bu)會松(song)動(dong)或(huo)引(yin)起膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)和軸(zhou)(zhou)套(tao)之間的(de)(de)反沖。有一(yi)些生產商(shang)提供兩個膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)的(de)(de)，也(ye)有提供三(san)個膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)的(de)(de)，中間有一(yi)個或(huo)兩個剛性元件，兩邊 再連在(zai)軸(zhou)(zhou)套(tao)上(shang)。單膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)器(qi)和雙膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)器(qi)的(de)(de)不(bu)同(tong)之處是處理(li)各種偏(pian)差能力的(de)(de)不(bu)同(tong)，鑒(jian)于其需要膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)能復(fu)雜(za)的(de)(de)彎曲(qu)，所(suo)以單膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)器(qi)不(bu)太(tai)適應偏(pian)心。而雙膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)器(qi)可以同(tong)時曲(qu)向(xiang)不(bu)同(tong)的(de)(de)方向(xiang)，以此來補(bu)償偏(pian)心。
