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(chuan)遞扭矩大，使(shi)用壽命長，免維護，耐高溫，耐酸堿防腐(fu)蝕，適用于高溫高速及有腐(fu)蝕工況環境(jing)的軸(zhou)系(xi)傳(chuan)動。

膜片(pian)型聯(lian)軸(zhou)器(qi)能補償主(zhu)動(dong)機(ji)與從動(dong)機(ji)之間由于制造誤(wu)(wu)差、安裝誤(wu)(wu)差、承(cheng)載變形(xing)以(yi)及溫升(sheng)變化的(de)影(ying)響(xiang)等所引(yin)起的(de)軸(zhou)向(xiang)(xiang)、徑向(xiang)(xiang)和角向(xiang)(xiang)偏移。膜片(pian)彈(dan)(dan)性聯(lian)軸(zhou)器(qi)屬金屬彈(dan)(dan)性元件撓性聯(lian)軸(zhou)器(qi)，其依(yi)靠金屬聯(lian)軸(zhou)器(qi)膜片(pian)來聯(lian)接主(zhu)、從動(dong)機(ji)傳遞扭矩，具(ju)有彈(dan)(dan)性減振(zhen)、無噪聲、不(bu)需潤滑的(de)優(you)點。

膜片(pian)(pian)聯(lian)(lian)軸(zhou)器至(zhi)少由一(yi)(yi)個(ge)膜片(pian)(pian)和兩(liang)(liang)個(ge)軸(zhou)套組成。膜片(pian)(pian)被用銷釘緊固在軸(zhou)套上一(yi)(yi)般不會(hui)松動或(huo)引(yin)起膜片(pian)(pian)和軸(zhou)套之間(jian)的(de)(de)(de)反(fan)沖(chong)。有一(yi)(yi)些(xie)生產商提供(gong)兩(liang)(liang)個(ge)膜片(pian)(pian)的(de)(de)(de)，也有提供(gong)三個(ge)膜片(pian)(pian)的(de)(de)(de)，中(zhong)間(jian)有一(yi)(yi)個(ge)或(huo)兩(liang)(liang)個(ge)剛(gang)性元件，兩(liang)(liang)邊 再連在軸(zhou)套上。單(dan)膜片(pian)(pian)聯(lian)(lian)軸(zhou)器和雙(shuang)膜片(pian)(pian)聯(lian)(lian)軸(zhou)器的(de)(de)(de)不同(tong)(tong)(tong)之處(chu)(chu)是處(chu)(chu)理各種偏(pian)差能力的(de)(de)(de)不同(tong)(tong)(tong)，鑒于其需要膜片(pian)(pian)能復雜(za)的(de)(de)(de)彎(wan)曲(qu)，所以單(dan)膜片(pian)(pian)聯(lian)(lian)軸(zhou)器不太適應(ying)偏(pian)心。而雙(shuang)膜片(pian)(pian)聯(lian)(lian)軸(zhou)器可(ke)以同(tong)(tong)(tong)時曲(qu)向不同(tong)(tong)(tong)的(de)(de)(de)方向，以此來(lai)補償偏(pian)心。
