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(chuan)遞(di)扭矩大，使用(yong)壽命長，免維護，耐高(gao)溫(wen)，耐酸堿防腐蝕，適用(yong)于(yu)高(gao)溫(wen)高(gao)速及(ji)有腐蝕工況環(huan)境的軸系傳(chuan)動。

膜(mo)(mo)片(pian)型聯(lian)軸(zhou)器(qi)(qi)能(neng)補償(chang)主動機(ji)與從(cong)動機(ji)之(zhi)間由于制造(zao)誤差、安裝誤差、承(cheng)載變形以及溫升變化的影響(xiang)等所(suo)引起(qi)的軸(zhou)向、徑向和角(jiao)向偏(pian)移。膜(mo)(mo)片(pian)彈(dan)性聯(lian)軸(zhou)器(qi)(qi)屬金屬彈(dan)性元(yuan)件撓性聯(lian)軸(zhou)器(qi)(qi)，其依(yi)靠(kao)金屬聯(lian)軸(zhou)器(qi)(qi)膜(mo)(mo)片(pian)來聯(lian)接主、從(cong)動機(ji)傳遞扭矩，具有彈(dan)性減(jian)振、無噪(zao)聲(sheng)、不需潤(run)滑的優點。

膜(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)器(qi)至(zhi)少(shao)由一(yi)個(ge)膜(mo)(mo)片(pian)(pian)(pian)(pian)和兩個(ge)軸(zhou)套(tao)(tao)組成。膜(mo)(mo)片(pian)(pian)(pian)(pian)被用銷釘緊固在(zai)軸(zhou)套(tao)(tao)上一(yi)般不會松動(dong)或(huo)(huo)引起膜(mo)(mo)片(pian)(pian)(pian)(pian)和軸(zhou)套(tao)(tao)之間的(de)反沖(chong)。有一(yi)些生產商(shang)提供兩個(ge)膜(mo)(mo)片(pian)(pian)(pian)(pian)的(de)，也(ye)有提供三個(ge)膜(mo)(mo)片(pian)(pian)(pian)(pian)的(de)，中間有一(yi)個(ge)或(huo)(huo)兩個(ge)剛性(xing)元件，兩邊 再連在(zai)軸(zhou)套(tao)(tao)上。單膜(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)器(qi)和雙膜(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)器(qi)的(de)不同(tong)之處是處理各種(zhong)偏(pian)差(cha)能力的(de)不同(tong)，鑒于其需要(yao)膜(mo)(mo)片(pian)(pian)(pian)(pian)能復雜的(de)彎(wan)曲，所以(yi)單膜(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)器(qi)不太(tai)適應(ying)偏(pian)心(xin)。而雙膜(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)器(qi)可(ke)以(yi)同(tong)時曲向(xiang)不同(tong)的(de)方向(xiang)，以(yi)此來(lai)補(bu)償偏(pian)心(xin)。
