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(shou)命(ming)長(chang)，免維護，耐高(gao)溫，耐酸堿防腐(fu)(fu)蝕，適用于高(gao)溫高(gao)速及有腐(fu)(fu)蝕工況環(huan)境的軸系傳動。

膜(mo)片(pian)型聯軸(zhou)(zhou)器能補償(chang)主動機(ji)與從動機(ji)之間由于(yu)制造(zao)誤差(cha)、安裝誤差(cha)、承(cheng)載變形(xing)以及(ji)溫升(sheng)變化的影(ying)響等所引(yin)起(qi)的軸(zhou)(zhou)向、徑向和角向偏移。膜(mo)片(pian)彈(dan)性(xing)聯軸(zhou)(zhou)器屬(shu)金(jin)屬(shu)彈(dan)性(xing)元件撓性(xing)聯軸(zhou)(zhou)器，其依靠(kao)金(jin)屬(shu)聯軸(zhou)(zhou)器膜(mo)片(pian)來聯接(jie)主、從動機(ji)傳遞(di)扭矩(ju)，具有彈(dan)性(xing)減振、無噪聲、不(bu)需潤滑的優點(dian)。

膜(mo)片(pian)(pian)(pian)(pian)聯(lian)軸(zhou)(zhou)器(qi)至少由一(yi)個膜(mo)片(pian)(pian)(pian)(pian)和兩個軸(zhou)(zhou)套組成。膜(mo)片(pian)(pian)(pian)(pian)被(bei)用銷釘緊固在軸(zhou)(zhou)套上(shang)一(yi)般不(bu)會松動或引起膜(mo)片(pian)(pian)(pian)(pian)和軸(zhou)(zhou)套之間(jian)的(de)(de)(de)(de)反沖(chong)。有(you)一(yi)些生產商提(ti)供(gong)兩個膜(mo)片(pian)(pian)(pian)(pian)的(de)(de)(de)(de)，也有(you)提(ti)供(gong)三個膜(mo)片(pian)(pian)(pian)(pian)的(de)(de)(de)(de)，中間(jian)有(you)一(yi)個或兩個剛性元件，兩邊 再連(lian)在軸(zhou)(zhou)套上(shang)。單(dan)(dan)膜(mo)片(pian)(pian)(pian)(pian)聯(lian)軸(zhou)(zhou)器(qi)和雙(shuang)膜(mo)片(pian)(pian)(pian)(pian)聯(lian)軸(zhou)(zhou)器(qi)的(de)(de)(de)(de)不(bu)同(tong)(tong)之處是處理各(ge)種偏(pian)(pian)差能力的(de)(de)(de)(de)不(bu)同(tong)(tong)，鑒于其需要膜(mo)片(pian)(pian)(pian)(pian)能復雜的(de)(de)(de)(de)彎曲(qu)，所以單(dan)(dan)膜(mo)片(pian)(pian)(pian)(pian)聯(lian)軸(zhou)(zhou)器(qi)不(bu)太(tai)適應偏(pian)(pian)心。而雙(shuang)膜(mo)片(pian)(pian)(pian)(pian)聯(lian)軸(zhou)(zhou)器(qi)可以同(tong)(tong)時(shi)曲(qu)向(xiang)不(bu)同(tong)(tong)的(de)(de)(de)(de)方向(xiang)，以此(ci)來(lai)補償(chang)偏(pian)(pian)心。
