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)，傳遞扭矩大，使(shi)用(yong)壽命長(chang)，免維護，耐高溫(wen)，耐酸堿防腐蝕(shi)，適用(yong)于高溫(wen)高速及有(you)腐蝕(shi)工況環(huan)境的軸系傳動(dong)。

膜片型聯(lian)(lian)(lian)(lian)軸器(qi)能補償主(zhu)動(dong)機與(yu)從(cong)動(dong)機之(zhi)間由(you)于制(zhi)造誤(wu)差(cha)、安裝誤(wu)差(cha)、承(cheng)載變(bian)形以及溫(wen)升(sheng)變(bian)化(hua)的(de)(de)影響等所引(yin)起的(de)(de)軸向(xiang)(xiang)、徑向(xiang)(xiang)和角向(xiang)(xiang)偏移。膜片彈(dan)性(xing)聯(lian)(lian)(lian)(lian)軸器(qi)屬金(jin)屬彈(dan)性(xing)元(yuan)件撓性(xing)聯(lian)(lian)(lian)(lian)軸器(qi)，其依靠金(jin)屬聯(lian)(lian)(lian)(lian)軸器(qi)膜片來聯(lian)(lian)(lian)(lian)接(jie)主(zhu)、從(cong)動(dong)機傳遞(di)扭矩，具有彈(dan)性(xing)減振(zhen)、無噪聲(sheng)、不需潤(run)滑的(de)(de)優點。

膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)聯軸(zhou)(zhou)器(qi)(qi)至(zhi)少由一個(ge)(ge)膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)和兩(liang)個(ge)(ge)軸(zhou)(zhou)套(tao)(tao)組成。膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)被用(yong)銷(xiao)釘緊固在(zai)(zai)軸(zhou)(zhou)套(tao)(tao)上一般不(bu)會松(song)動或引起膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)和軸(zhou)(zhou)套(tao)(tao)之間(jian)的(de)反沖。有(you)(you)一些生(sheng)產商(shang)提(ti)供兩(liang)個(ge)(ge)膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)的(de)，也有(you)(you)提(ti)供三個(ge)(ge)膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)的(de)，中間(jian)有(you)(you)一個(ge)(ge)或兩(liang)個(ge)(ge)剛性元件，兩(liang)邊 再連在(zai)(zai)軸(zhou)(zhou)套(tao)(tao)上。單(dan)膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)聯軸(zhou)(zhou)器(qi)(qi)和雙膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)聯軸(zhou)(zhou)器(qi)(qi)的(de)不(bu)同之處(chu)是(shi)處(chu)理各種偏(pian)(pian)差能力(li)的(de)不(bu)同，鑒于其需要膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)能復雜的(de)彎曲，所以單(dan)膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)聯軸(zhou)(zhou)器(qi)(qi)不(bu)太適應偏(pian)(pian)心。而雙膜(mo)(mo)(mo)(mo)片(pian)(pian)(pian)聯軸(zhou)(zhou)器(qi)(qi)可以同時曲向不(bu)同的(de)方(fang)向，以此來補償偏(pian)(pian)心。
