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(cou)，傳遞扭矩大，使用(yong)壽命(ming)長，免維護，耐高溫，耐酸堿防腐蝕，適用(yong)于高溫高速及有腐蝕工況環境(jing)的軸系傳動。

膜片(pian)(pian)型聯(lian)(lian)軸(zhou)器能補(bu)償主動(dong)(dong)機與從動(dong)(dong)機之間由于制造誤差、安裝誤差、承載(zai)變形以及(ji)溫升變化的影響等所引起的軸(zhou)向(xiang)(xiang)、徑向(xiang)(xiang)和角向(xiang)(xiang)偏(pian)移。膜片(pian)(pian)彈性聯(lian)(lian)軸(zhou)器屬金屬彈性元件撓性聯(lian)(lian)軸(zhou)器，其依(yi)靠金屬聯(lian)(lian)軸(zhou)器膜片(pian)(pian)來(lai)聯(lian)(lian)接(jie)主、從動(dong)(dong)機傳遞扭矩(ju)，具有(you)彈性減振、無噪聲、不需潤滑的優點。

膜(mo)(mo)(mo)(mo)(mo)(mo)片(pian)(pian)聯(lian)(lian)(lian)軸器(qi)至少(shao)由一個膜(mo)(mo)(mo)(mo)(mo)(mo)片(pian)(pian)和兩(liang)(liang)個軸套(tao)組成。膜(mo)(mo)(mo)(mo)(mo)(mo)片(pian)(pian)被(bei)用銷釘緊固在軸套(tao)上(shang)一般(ban)不(bu)(bu)會松動或(huo)引起膜(mo)(mo)(mo)(mo)(mo)(mo)片(pian)(pian)和軸套(tao)之間的反沖(chong)。有一些(xie)生產商提供兩(liang)(liang)個膜(mo)(mo)(mo)(mo)(mo)(mo)片(pian)(pian)的，也有提供三個膜(mo)(mo)(mo)(mo)(mo)(mo)片(pian)(pian)的，中(zhong)間有一個或(huo)兩(liang)(liang)個剛性元件，兩(liang)(liang)邊(bian) 再連在軸套(tao)上(shang)。單(dan)膜(mo)(mo)(mo)(mo)(mo)(mo)片(pian)(pian)聯(lian)(lian)(lian)軸器(qi)和雙(shuang)膜(mo)(mo)(mo)(mo)(mo)(mo)片(pian)(pian)聯(lian)(lian)(lian)軸器(qi)的不(bu)(bu)同(tong)之處是處理各種偏(pian)差(cha)能力的不(bu)(bu)同(tong)，鑒(jian)于其(qi)需要(yao)膜(mo)(mo)(mo)(mo)(mo)(mo)片(pian)(pian)能復雜(za)的彎(wan)曲，所以(yi)單(dan)膜(mo)(mo)(mo)(mo)(mo)(mo)片(pian)(pian)聯(lian)(lian)(lian)軸器(qi)不(bu)(bu)太適應偏(pian)心(xin)。而雙(shuang)膜(mo)(mo)(mo)(mo)(mo)(mo)片(pian)(pian)聯(lian)(lian)(lian)軸器(qi)可(ke)以(yi)同(tong)時(shi)曲向不(bu)(bu)同(tong)的方向，以(yi)此(ci)來補償(chang)偏(pian)心(xin)。
