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(ju)大，使用(yong)壽(shou)命長，免維(wei)護，耐高溫，耐酸堿防腐(fu)蝕，適用(yong)于高溫高速及有腐(fu)蝕工況(kuang)環境的(de)軸系傳動。

膜片(pian)(pian)型聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)(qi)能補償(chang)主動(dong)機與(yu)從(cong)動(dong)機之間由(you)于制造誤(wu)差、安裝誤(wu)差、承(cheng)載變形以及溫升(sheng)變化的(de)影響(xiang)等(deng)所引(yin)起的(de)軸(zhou)(zhou)向(xiang)、徑向(xiang)和角向(xiang)偏移。膜片(pian)(pian)彈(dan)性(xing)聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)(qi)屬金屬彈(dan)性(xing)元件(jian)撓(nao)性(xing)聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)(qi)，其(qi)依靠(kao)金屬聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)(qi)膜片(pian)(pian)來聯(lian)(lian)(lian)接(jie)主、從(cong)動(dong)機傳遞扭矩(ju)，具(ju)有彈(dan)性(xing)減振、無(wu)噪聲、不需潤滑的(de)優點。

膜(mo)片(pian)(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)器(qi)至少由一個(ge)(ge)膜(mo)片(pian)(pian)(pian)和兩(liang)個(ge)(ge)軸(zhou)(zhou)套組成(cheng)。膜(mo)片(pian)(pian)(pian)被用銷釘緊(jin)固(gu)在軸(zhou)(zhou)套上一般不(bu)會松動或引起膜(mo)片(pian)(pian)(pian)和軸(zhou)(zhou)套之間的(de)反沖。有一些(xie)生產商提供(gong)兩(liang)個(ge)(ge)膜(mo)片(pian)(pian)(pian)的(de)，也有提供(gong)三個(ge)(ge)膜(mo)片(pian)(pian)(pian)的(de)，中(zhong)間有一個(ge)(ge)或兩(liang)個(ge)(ge)剛性(xing)元件，兩(liang)邊 再連在軸(zhou)(zhou)套上。單膜(mo)片(pian)(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)器(qi)和雙(shuang)膜(mo)片(pian)(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)器(qi)的(de)不(bu)同(tong)之處是處理各種(zhong)偏差能力的(de)不(bu)同(tong)，鑒于其需要(yao)膜(mo)片(pian)(pian)(pian)能復雜的(de)彎曲，所以(yi)(yi)(yi)單膜(mo)片(pian)(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)器(qi)不(bu)太適(shi)應偏心。而雙(shuang)膜(mo)片(pian)(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)器(qi)可(ke)以(yi)(yi)(yi)同(tong)時(shi)曲向(xiang)不(bu)同(tong)的(de)方(fang)向(xiang)，以(yi)(yi)(yi)此來補償偏心。
