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(di)扭矩(ju)大，使用壽(shou)命(ming)長，免維護(hu)，耐高(gao)溫，耐酸堿防腐蝕(shi)(shi)，適用于高(gao)溫高(gao)速(su)及有腐蝕(shi)(shi)工況環(huan)境的軸系傳(chuan)動。

膜片型聯軸器(qi)(qi)(qi)能補償主(zhu)動(dong)機(ji)與從動(dong)機(ji)之(zhi)間由于制(zhi)造誤差、安裝誤差、承載(zai)變(bian)形以及溫升變(bian)化(hua)的(de)影響等所引起的(de)軸向、徑向和角向偏移。膜片彈性聯軸器(qi)(qi)(qi)屬金屬彈性元(yuan)件撓性聯軸器(qi)(qi)(qi)，其依靠金屬聯軸器(qi)(qi)(qi)膜片來聯接(jie)主(zhu)、從動(dong)機(ji)傳遞扭矩，具(ju)有彈性減振、無噪聲、不需潤滑的(de)優點。

膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)(pian)聯(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)至少由一(yi)個(ge)膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)(pian)和兩(liang)個(ge)軸(zhou)(zhou)(zhou)套(tao)組成。膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)(pian)被用銷釘緊固在軸(zhou)(zhou)(zhou)套(tao)上一(yi)般(ban)不(bu)會松(song)動或引起(qi)膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)(pian)和軸(zhou)(zhou)(zhou)套(tao)之(zhi)間的(de)反沖(chong)。有一(yi)些(xie)生(sheng)產商提(ti)(ti)供(gong)(gong)兩(liang)個(ge)膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)(pian)的(de)，也有提(ti)(ti)供(gong)(gong)三個(ge)膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)(pian)的(de)，中間有一(yi)個(ge)或兩(liang)個(ge)剛(gang)性元件，兩(liang)邊 再連(lian)在軸(zhou)(zhou)(zhou)套(tao)上。單(dan)膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)(pian)聯(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)和雙膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)(pian)聯(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)的(de)不(bu)同之(zhi)處是(shi)處理各種偏差能(neng)力的(de)不(bu)同，鑒(jian)于其需要膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)(pian)能(neng)復(fu)雜的(de)彎曲(qu)，所以單(dan)膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)(pian)聯(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)不(bu)太適應偏心。而雙膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)(pian)聯(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)可以同時(shi)曲(qu)向不(bu)同的(de)方向，以此來補(bu)償偏心。
