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(jie)構緊(jin)湊，傳遞(di)扭矩(ju)大，使(shi)用(yong)壽命(ming)長，免維(wei)護，耐高溫(wen)，耐酸堿(jian)防腐(fu)蝕，適(shi)用(yong)于高溫(wen)高速及有(you)腐(fu)蝕工況環境的軸(zhou)系傳動(dong)。

膜(mo)片型聯(lian)(lian)軸(zhou)器(qi)(qi)能補(bu)償主動機(ji)與從(cong)動機(ji)之間由于制造誤差、安裝誤差、承載變形以及溫升變化(hua)的(de)影響等所引起的(de)軸(zhou)向(xiang)、徑向(xiang)和角向(xiang)偏移。膜(mo)片彈性(xing)聯(lian)(lian)軸(zhou)器(qi)(qi)屬金屬彈性(xing)元件撓(nao)性(xing)聯(lian)(lian)軸(zhou)器(qi)(qi)，其(qi)依靠(kao)金屬聯(lian)(lian)軸(zhou)器(qi)(qi)膜(mo)片來聯(lian)(lian)接主、從(cong)動機(ji)傳遞扭矩，具有(you)彈性(xing)減振、無噪聲、不需潤滑的(de)優點。

膜(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)器至少由一(yi)(yi)個膜(mo)片(pian)(pian)(pian)(pian)和(he)兩(liang)個軸(zhou)套(tao)(tao)組成(cheng)。膜(mo)片(pian)(pian)(pian)(pian)被用(yong)銷釘緊固在(zai)軸(zhou)套(tao)(tao)上(shang)一(yi)(yi)般(ban)不(bu)會松動或引起(qi)膜(mo)片(pian)(pian)(pian)(pian)和(he)軸(zhou)套(tao)(tao)之間(jian)的(de)(de)反沖。有(you)(you)一(yi)(yi)些生產商(shang)提(ti)供兩(liang)個膜(mo)片(pian)(pian)(pian)(pian)的(de)(de)，也有(you)(you)提(ti)供三個膜(mo)片(pian)(pian)(pian)(pian)的(de)(de)，中間(jian)有(you)(you)一(yi)(yi)個或兩(liang)個剛性(xing)元件，兩(liang)邊 再連在(zai)軸(zhou)套(tao)(tao)上(shang)。單(dan)膜(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)器和(he)雙膜(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)器的(de)(de)不(bu)同之處是處理各(ge)種偏差能力(li)的(de)(de)不(bu)同，鑒(jian)于(yu)其(qi)需要膜(mo)片(pian)(pian)(pian)(pian)能復雜(za)的(de)(de)彎曲，所以單(dan)膜(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)器不(bu)太適應偏心。而雙膜(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)器可(ke)以同時曲向(xiang)不(bu)同的(de)(de)方向(xiang)，以此(ci)來補(bu)償偏心。
