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，傳遞扭矩大，使用壽命長(chang)，免維(wei)護，耐高溫，耐酸堿(jian)防腐(fu)蝕(shi)，適用于高溫高速及有腐(fu)蝕(shi)工況環境的軸系傳動。

膜(mo)片(pian)(pian)型(xing)聯軸(zhou)器(qi)(qi)(qi)能補償主(zhu)動(dong)機(ji)(ji)與從動(dong)機(ji)(ji)之(zhi)間由于制造誤(wu)差、安裝(zhuang)誤(wu)差、承載變(bian)形以及溫升變(bian)化(hua)的(de)影響等所(suo)引起的(de)軸(zhou)向(xiang)、徑向(xiang)和角向(xiang)偏移。膜(mo)片(pian)(pian)彈(dan)性(xing)聯軸(zhou)器(qi)(qi)(qi)屬(shu)金屬(shu)彈(dan)性(xing)元件撓性(xing)聯軸(zhou)器(qi)(qi)(qi)，其依靠金屬(shu)聯軸(zhou)器(qi)(qi)(qi)膜(mo)片(pian)(pian)來聯接(jie)主(zhu)、從動(dong)機(ji)(ji)傳遞扭矩，具有(you)彈(dan)性(xing)減振(zhen)、無(wu)噪聲、不需潤滑(hua)的(de)優點。

膜片(pian)(pian)(pian)(pian)聯軸(zhou)器(qi)至少由一個膜片(pian)(pian)(pian)(pian)和(he)兩(liang)個軸(zhou)套(tao)組成。膜片(pian)(pian)(pian)(pian)被(bei)用銷釘緊固在(zai)軸(zhou)套(tao)上(shang)一般不會松動或(huo)引(yin)起膜片(pian)(pian)(pian)(pian)和(he)軸(zhou)套(tao)之(zhi)間的(de)(de)(de)反沖。有(you)一些生(sheng)產商提供兩(liang)個膜片(pian)(pian)(pian)(pian)的(de)(de)(de)，也有(you)提供三(san)個膜片(pian)(pian)(pian)(pian)的(de)(de)(de)，中間有(you)一個或(huo)兩(liang)個剛性元(yuan)件，兩(liang)邊 再連在(zai)軸(zhou)套(tao)上(shang)。單膜片(pian)(pian)(pian)(pian)聯軸(zhou)器(qi)和(he)雙膜片(pian)(pian)(pian)(pian)聯軸(zhou)器(qi)的(de)(de)(de)不同(tong)(tong)之(zhi)處是處理各種偏差能力的(de)(de)(de)不同(tong)(tong)，鑒于其(qi)需(xu)要膜片(pian)(pian)(pian)(pian)能復雜的(de)(de)(de)彎曲(qu)，所以單膜片(pian)(pian)(pian)(pian)聯軸(zhou)器(qi)不太適應(ying)偏心。而雙膜片(pian)(pian)(pian)(pian)聯軸(zhou)器(qi)可以同(tong)(tong)時曲(qu)向不同(tong)(tong)的(de)(de)(de)方向，以此來(lai)補償(chang)偏心。
