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(jie)構緊湊，傳遞(di)扭矩大，使用壽命長，免維護，耐高溫，耐酸(suan)堿(jian)防(fang)腐(fu)蝕(shi)，適(shi)用于高溫高速及有腐(fu)蝕(shi)工況(kuang)環境的軸系傳動。

膜片(pian)型聯(lian)(lian)軸(zhou)器能(neng)補償主(zhu)(zhu)動(dong)機與從動(dong)機之(zhi)間(jian)由(you)于(yu)制(zhi)造誤(wu)(wu)差(cha)、安裝誤(wu)(wu)差(cha)、承載變(bian)形以及溫升變(bian)化(hua)的影響等(deng)所引起的軸(zhou)向、徑向和角向偏移。膜片(pian)彈(dan)性聯(lian)(lian)軸(zhou)器屬(shu)金屬(shu)彈(dan)性元件撓性聯(lian)(lian)軸(zhou)器，其依靠金屬(shu)聯(lian)(lian)軸(zhou)器膜片(pian)來聯(lian)(lian)接主(zhu)(zhu)、從動(dong)機傳遞扭(niu)矩，具有(you)彈(dan)性減振、無(wu)噪聲、不需潤滑的優(you)點。

膜片(pian)(pian)(pian)聯軸(zhou)(zhou)器(qi)至(zhi)少由一(yi)個膜片(pian)(pian)(pian)和(he)兩(liang)個軸(zhou)(zhou)套(tao)組成(cheng)。膜片(pian)(pian)(pian)被(bei)用(yong)銷釘緊固在軸(zhou)(zhou)套(tao)上(shang)一(yi)般不(bu)會(hui)松動或(huo)引起膜片(pian)(pian)(pian)和(he)軸(zhou)(zhou)套(tao)之間的反沖(chong)。有一(yi)些生產商提(ti)供(gong)兩(liang)個膜片(pian)(pian)(pian)的，也有提(ti)供(gong)三個膜片(pian)(pian)(pian)的，中間有一(yi)個或(huo)兩(liang)個剛性元件，兩(liang)邊 再連(lian)在軸(zhou)(zhou)套(tao)上(shang)。單膜片(pian)(pian)(pian)聯軸(zhou)(zhou)器(qi)和(he)雙(shuang)膜片(pian)(pian)(pian)聯軸(zhou)(zhou)器(qi)的不(bu)同(tong)(tong)(tong)之處(chu)是處(chu)理各種偏(pian)差能力的不(bu)同(tong)(tong)(tong)，鑒于其需要(yao)膜片(pian)(pian)(pian)能復雜的彎(wan)曲，所以(yi)單膜片(pian)(pian)(pian)聯軸(zhou)(zhou)器(qi)不(bu)太適應偏(pian)心(xin)。而雙(shuang)膜片(pian)(pian)(pian)聯軸(zhou)(zhou)器(qi)可以(yi)同(tong)(tong)(tong)時曲向不(bu)同(tong)(tong)(tong)的方向，以(yi)此來補償偏(pian)心(xin)。
