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，傳遞扭矩大，使用壽命長(chang)，免維護，耐高(gao)溫(wen)，耐酸堿(jian)防腐(fu)蝕(shi)，適用于(yu)高(gao)溫(wen)高(gao)速及有腐(fu)蝕(shi)工況環境的軸系傳動。

膜(mo)片型聯(lian)軸(zhou)器(qi)能補償(chang)主動(dong)機(ji)(ji)與從(cong)(cong)動(dong)機(ji)(ji)之間由于制造(zao)誤差、安(an)裝誤差、承載(zai)變(bian)(bian)形以及溫升變(bian)(bian)化的影響等(deng)所引(yin)起的軸(zhou)向(xiang)、徑向(xiang)和(he)角向(xiang)偏移。膜(mo)片彈性聯(lian)軸(zhou)器(qi)屬金(jin)屬彈性元(yuan)件撓性聯(lian)軸(zhou)器(qi)，其依靠金(jin)屬聯(lian)軸(zhou)器(qi)膜(mo)片來(lai)聯(lian)接主、從(cong)(cong)動(dong)機(ji)(ji)傳遞扭矩，具有(you)彈性減(jian)振(zhen)、無噪(zao)聲(sheng)、不需(xu)潤滑的優點。

膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)器(qi)至少(shao)由一(yi)個膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)(pian)和兩個軸(zhou)套(tao)組成。膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)(pian)被用銷(xiao)釘緊固在(zai)(zai)軸(zhou)套(tao)上(shang)一(yi)般不(bu)會(hui)松動或(huo)引起(qi)膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)(pian)和軸(zhou)套(tao)之間的反沖。有一(yi)些生(sheng)產商提供兩個膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)(pian)的，也有提供三(san)個膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)(pian)的，中(zhong)間有一(yi)個或(huo)兩個剛性元(yuan)件，兩邊 再連在(zai)(zai)軸(zhou)套(tao)上(shang)。單膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)器(qi)和雙(shuang)膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)器(qi)的不(bu)同(tong)之處是處理(li)各(ge)種偏(pian)差能力的不(bu)同(tong)，鑒(jian)于其需要膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)(pian)能復雜的彎(wan)曲，所以單膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)器(qi)不(bu)太適應偏(pian)心(xin)。而雙(shuang)膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)器(qi)可(ke)以同(tong)時曲向不(bu)同(tong)的方向，以此(ci)來補償偏(pian)心(xin)。
