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)構緊湊，傳遞扭矩大，使用壽命長，免(mian)維護，耐高(gao)溫，耐酸堿防腐(fu)蝕(shi)，適用于高(gao)溫高(gao)速及有腐(fu)蝕(shi)工況環(huan)境(jing)的(de)軸系傳動。

膜片(pian)型聯(lian)(lian)軸器能補償(chang)主動(dong)機(ji)與從(cong)動(dong)機(ji)之(zhi)間由于(yu)制造誤差、安(an)裝誤差、承載變(bian)形以(yi)及溫升變(bian)化的影響等所引(yin)起(qi)的軸向(xiang)、徑向(xiang)和角向(xiang)偏移(yi)。膜片(pian)彈性(xing)聯(lian)(lian)軸器屬金屬彈性(xing)元(yuan)件撓性(xing)聯(lian)(lian)軸器，其依靠金屬聯(lian)(lian)軸器膜片(pian)來聯(lian)(lian)接主、從(cong)動(dong)機(ji)傳遞扭矩，具(ju)有彈性(xing)減振、無噪聲(sheng)、不需潤滑的優點。

膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)(zhou)器至少由一個膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)和兩個軸(zhou)(zhou)(zhou)套組成。膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)被用(yong)銷釘緊(jin)固在軸(zhou)(zhou)(zhou)套上一般不(bu)(bu)(bu)會(hui)松動或引起膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)和軸(zhou)(zhou)(zhou)套之間(jian)的反沖。有(you)一些生(sheng)產商(shang)提(ti)供兩個膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)的，也(ye)有(you)提(ti)供三個膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)的，中間(jian)有(you)一個或兩個剛性(xing)元件，兩邊 再(zai)連在軸(zhou)(zhou)(zhou)套上。單膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)(zhou)器和雙膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)(zhou)器的不(bu)(bu)(bu)同(tong)之處(chu)是處(chu)理各種偏差(cha)能力的不(bu)(bu)(bu)同(tong)，鑒于其需要膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)能復(fu)雜的彎曲，所以單膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)(zhou)器不(bu)(bu)(bu)太適應(ying)偏心。而雙膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)(zhou)器可(ke)以同(tong)時曲向(xiang)不(bu)(bu)(bu)同(tong)的方(fang)向(xiang)，以此來補(bu)償偏心。
