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)(chuan)遞扭矩大(da)，使用壽(shou)命長，免維(wei)護，耐高(gao)(gao)溫(wen)，耐酸(suan)堿防腐蝕，適用于高(gao)(gao)溫(wen)高(gao)(gao)速及(ji)有腐蝕工(gong)況環境的軸系傳(chuan)(chuan)動。

膜片型聯(lian)(lian)軸(zhou)器能補(bu)償(chang)主動(dong)機(ji)與從動(dong)機(ji)之間由于制造誤差、安裝誤差、承載(zai)變形以及(ji)溫升變化的影(ying)響等所(suo)引起的軸(zhou)向(xiang)(xiang)(xiang)、徑向(xiang)(xiang)(xiang)和角向(xiang)(xiang)(xiang)偏移(yi)。膜片彈(dan)(dan)性(xing)聯(lian)(lian)軸(zhou)器屬(shu)金(jin)(jin)屬(shu)彈(dan)(dan)性(xing)元件(jian)撓性(xing)聯(lian)(lian)軸(zhou)器，其依(yi)靠(kao)金(jin)(jin)屬(shu)聯(lian)(lian)軸(zhou)器膜片來聯(lian)(lian)接主、從動(dong)機(ji)傳遞扭矩(ju)，具有(you)彈(dan)(dan)性(xing)減振、無噪聲(sheng)、不需潤(run)滑的優點。

膜(mo)(mo)(mo)片(pian)(pian)(pian)聯軸(zhou)器(qi)(qi)至少由一(yi)個(ge)(ge)膜(mo)(mo)(mo)片(pian)(pian)(pian)和(he)兩個(ge)(ge)軸(zhou)套組成。膜(mo)(mo)(mo)片(pian)(pian)(pian)被用(yong)銷釘緊固在軸(zhou)套上(shang)一(yi)般(ban)不(bu)(bu)會(hui)松(song)動或引(yin)起(qi)膜(mo)(mo)(mo)片(pian)(pian)(pian)和(he)軸(zhou)套之(zhi)間的(de)(de)反沖。有一(yi)些生產商(shang)提供兩個(ge)(ge)膜(mo)(mo)(mo)片(pian)(pian)(pian)的(de)(de)，也有提供三個(ge)(ge)膜(mo)(mo)(mo)片(pian)(pian)(pian)的(de)(de)，中間有一(yi)個(ge)(ge)或兩個(ge)(ge)剛性元件，兩邊 再連在軸(zhou)套上(shang)。單膜(mo)(mo)(mo)片(pian)(pian)(pian)聯軸(zhou)器(qi)(qi)和(he)雙膜(mo)(mo)(mo)片(pian)(pian)(pian)聯軸(zhou)器(qi)(qi)的(de)(de)不(bu)(bu)同(tong)(tong)(tong)之(zhi)處(chu)是處(chu)理各種(zhong)偏差能力(li)的(de)(de)不(bu)(bu)同(tong)(tong)(tong)，鑒(jian)于其需要(yao)膜(mo)(mo)(mo)片(pian)(pian)(pian)能復雜(za)的(de)(de)彎曲，所以(yi)單膜(mo)(mo)(mo)片(pian)(pian)(pian)聯軸(zhou)器(qi)(qi)不(bu)(bu)太適應偏心。而雙膜(mo)(mo)(mo)片(pian)(pian)(pian)聯軸(zhou)器(qi)(qi)可以(yi)同(tong)(tong)(tong)時曲向不(bu)(bu)同(tong)(tong)(tong)的(de)(de)方向，以(yi)此來補償偏心。
