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，傳遞扭矩大，使用壽命長，免(mian)維護，耐高(gao)溫，耐酸堿防腐蝕(shi)，適(shi)用于高(gao)溫高(gao)速及(ji)有腐蝕(shi)工況環境的(de)軸(zhou)系傳動(dong)。

膜片型聯(lian)(lian)(lian)軸(zhou)器(qi)(qi)(qi)能補償主動(dong)機(ji)與(yu)從(cong)動(dong)機(ji)之間由于(yu)制造誤差、安裝(zhuang)誤差、承載變形以及溫升(sheng)變化的影響等(deng)所引起的軸(zhou)向(xiang)(xiang)、徑向(xiang)(xiang)和角向(xiang)(xiang)偏移。膜片彈性聯(lian)(lian)(lian)軸(zhou)器(qi)(qi)(qi)屬(shu)金屬(shu)彈性元件(jian)撓性聯(lian)(lian)(lian)軸(zhou)器(qi)(qi)(qi)，其依靠金屬(shu)聯(lian)(lian)(lian)軸(zhou)器(qi)(qi)(qi)膜片來聯(lian)(lian)(lian)接主、從(cong)動(dong)機(ji)傳遞扭矩(ju)，具有彈性減振、無(wu)噪聲(sheng)、不需潤(run)滑(hua)的優點。

膜(mo)(mo)(mo)片(pian)(pian)(pian)聯(lian)軸器至少(shao)由一(yi)(yi)(yi)個(ge)膜(mo)(mo)(mo)片(pian)(pian)(pian)和(he)兩(liang)個(ge)軸套組成。膜(mo)(mo)(mo)片(pian)(pian)(pian)被用銷釘緊固在軸套上一(yi)(yi)(yi)般不(bu)會松動或(huo)引起膜(mo)(mo)(mo)片(pian)(pian)(pian)和(he)軸套之(zhi)間(jian)的反沖。有一(yi)(yi)(yi)些生產商(shang)提(ti)供(gong)兩(liang)個(ge)膜(mo)(mo)(mo)片(pian)(pian)(pian)的，也(ye)有提(ti)供(gong)三個(ge)膜(mo)(mo)(mo)片(pian)(pian)(pian)的，中間(jian)有一(yi)(yi)(yi)個(ge)或(huo)兩(liang)個(ge)剛性(xing)元件，兩(liang)邊 再(zai)連在軸套上。單膜(mo)(mo)(mo)片(pian)(pian)(pian)聯(lian)軸器和(he)雙(shuang)膜(mo)(mo)(mo)片(pian)(pian)(pian)聯(lian)軸器的不(bu)同(tong)(tong)之(zhi)處是處理各種偏差能力的不(bu)同(tong)(tong)，鑒(jian)于其需(xu)要膜(mo)(mo)(mo)片(pian)(pian)(pian)能復雜的彎曲，所以單膜(mo)(mo)(mo)片(pian)(pian)(pian)聯(lian)軸器不(bu)太適應偏心。而雙(shuang)膜(mo)(mo)(mo)片(pian)(pian)(pian)聯(lian)軸器可以同(tong)(tong)時曲向(xiang)(xiang)不(bu)同(tong)(tong)的方向(xiang)(xiang)，以此(ci)來(lai)補償偏心。
