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)遞扭矩大(da)，使用壽(shou)命(ming)長(chang)，免維護，耐高溫，耐酸堿防腐(fu)蝕，適用于高溫高速及有腐(fu)蝕工況環境的軸(zhou)系傳(chuan)動(dong)。

膜片型聯軸(zhou)(zhou)器能補償主(zhu)(zhu)動機(ji)與從動機(ji)之(zhi)間由于制造誤(wu)差、安裝誤(wu)差、承載變(bian)形以及溫升變(bian)化的影響等所引起的軸(zhou)(zhou)向、徑向和角向偏移。膜片彈(dan)性(xing)(xing)(xing)聯軸(zhou)(zhou)器屬金(jin)屬彈(dan)性(xing)(xing)(xing)元件(jian)撓性(xing)(xing)(xing)聯軸(zhou)(zhou)器，其依靠(kao)金(jin)屬聯軸(zhou)(zhou)器膜片來聯接主(zhu)(zhu)、從動機(ji)傳遞扭(niu)矩，具有彈(dan)性(xing)(xing)(xing)減振、無噪聲(sheng)、不需潤滑的優點。

膜(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)(zhou)器(qi)至少由一個膜(mo)(mo)片(pian)(pian)(pian)(pian)和兩個軸(zhou)(zhou)(zhou)(zhou)(zhou)套(tao)組成。膜(mo)(mo)片(pian)(pian)(pian)(pian)被(bei)用銷釘緊固在(zai)軸(zhou)(zhou)(zhou)(zhou)(zhou)套(tao)上一般(ban)不(bu)(bu)(bu)會松動或引(yin)起(qi)膜(mo)(mo)片(pian)(pian)(pian)(pian)和軸(zhou)(zhou)(zhou)(zhou)(zhou)套(tao)之間的(de)(de)反(fan)沖。有一些生產商(shang)提供(gong)兩個膜(mo)(mo)片(pian)(pian)(pian)(pian)的(de)(de)，也(ye)有提供(gong)三個膜(mo)(mo)片(pian)(pian)(pian)(pian)的(de)(de)，中間有一個或兩個剛(gang)性(xing)元件，兩邊 再連在(zai)軸(zhou)(zhou)(zhou)(zhou)(zhou)套(tao)上。單膜(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)(zhou)器(qi)和雙(shuang)膜(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)(zhou)器(qi)的(de)(de)不(bu)(bu)(bu)同(tong)之處是處理各(ge)種偏差能(neng)力的(de)(de)不(bu)(bu)(bu)同(tong)，鑒于(yu)其(qi)需要(yao)膜(mo)(mo)片(pian)(pian)(pian)(pian)能(neng)復雜的(de)(de)彎曲，所以單膜(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)(zhou)器(qi)不(bu)(bu)(bu)太適應偏心(xin)。而雙(shuang)膜(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)(zhou)(zhou)(zhou)器(qi)可以同(tong)時(shi)曲向不(bu)(bu)(bu)同(tong)的(de)(de)方向，以此來補償偏心(xin)。
