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(chuan)遞扭矩(ju)大，使(shi)用(yong)壽命(ming)長，免維護，耐高(gao)溫，耐酸(suan)堿防腐蝕(shi)，適(shi)用(yong)于(yu)高(gao)溫高(gao)速(su)及(ji)有腐蝕(shi)工(gong)況環境(jing)的軸系傳(chuan)動。

膜(mo)(mo)片(pian)型聯(lian)軸(zhou)器能補償主動機(ji)與從動機(ji)之間由于制造誤(wu)差、安裝誤(wu)差、承載變形以(yi)及溫升(sheng)變化(hua)的影(ying)響等所引起的軸(zhou)向、徑向和角向偏移。膜(mo)(mo)片(pian)彈性(xing)聯(lian)軸(zhou)器屬金屬彈性(xing)元件撓性(xing)聯(lian)軸(zhou)器，其(qi)依靠金屬聯(lian)軸(zhou)器膜(mo)(mo)片(pian)來聯(lian)接主、從動機(ji)傳遞扭(niu)矩(ju)，具有(you)彈性(xing)減振、無噪聲、不需潤滑的優點。

膜(mo)片(pian)(pian)(pian)(pian)(pian)聯(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)至少由(you)一個(ge)膜(mo)片(pian)(pian)(pian)(pian)(pian)和兩(liang)(liang)個(ge)軸(zhou)(zhou)(zhou)套(tao)組成。膜(mo)片(pian)(pian)(pian)(pian)(pian)被用銷釘緊固在軸(zhou)(zhou)(zhou)套(tao)上一般(ban)不(bu)會松動或引(yin)起膜(mo)片(pian)(pian)(pian)(pian)(pian)和軸(zhou)(zhou)(zhou)套(tao)之間的反(fan)沖。有一些(xie)生產商提供兩(liang)(liang)個(ge)膜(mo)片(pian)(pian)(pian)(pian)(pian)的，也有提供三(san)個(ge)膜(mo)片(pian)(pian)(pian)(pian)(pian)的，中間有一個(ge)或兩(liang)(liang)個(ge)剛性(xing)元件，兩(liang)(liang)邊 再連在軸(zhou)(zhou)(zhou)套(tao)上。單(dan)膜(mo)片(pian)(pian)(pian)(pian)(pian)聯(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)和雙(shuang)膜(mo)片(pian)(pian)(pian)(pian)(pian)聯(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)的不(bu)同之處是處理各種偏差(cha)能(neng)力的不(bu)同，鑒于其(qi)需要膜(mo)片(pian)(pian)(pian)(pian)(pian)能(neng)復雜的彎曲，所以單(dan)膜(mo)片(pian)(pian)(pian)(pian)(pian)聯(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)不(bu)太(tai)適應偏心。而雙(shuang)膜(mo)片(pian)(pian)(pian)(pian)(pian)聯(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)可以同時曲向(xiang)不(bu)同的方向(xiang)，以此來補償偏心。
