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(gou)緊湊，傳遞扭矩大，使(shi)用壽命長，免維護，耐高溫，耐酸堿防腐蝕，適用于高溫高速及有腐蝕工況環境(jing)的軸系傳動(dong)。

膜片(pian)(pian)型聯(lian)軸器(qi)能補償主動(dong)機(ji)與從動(dong)機(ji)之間由于制造誤差、安裝誤差、承(cheng)載變(bian)形以及溫升變(bian)化的影響等(deng)所(suo)引(yin)起的軸向(xiang)、徑向(xiang)和角(jiao)向(xiang)偏移(yi)。膜片(pian)(pian)彈(dan)性聯(lian)軸器(qi)屬(shu)金屬(shu)彈(dan)性元(yuan)件撓性聯(lian)軸器(qi)，其(qi)依靠金屬(shu)聯(lian)軸器(qi)膜片(pian)(pian)來聯(lian)接主、從動(dong)機(ji)傳遞扭矩(ju)，具有彈(dan)性減振、無噪聲(sheng)、不(bu)需(xu)潤滑(hua)的優點。

膜(mo)片(pian)(pian)聯(lian)(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)至少由一(yi)個(ge)膜(mo)片(pian)(pian)和(he)(he)(he)兩(liang)個(ge)軸(zhou)(zhou)(zhou)套(tao)組成(cheng)。膜(mo)片(pian)(pian)被用銷(xiao)釘(ding)緊(jin)固在軸(zhou)(zhou)(zhou)套(tao)上(shang)一(yi)般不(bu)會松動或(huo)引起膜(mo)片(pian)(pian)和(he)(he)(he)軸(zhou)(zhou)(zhou)套(tao)之(zhi)間(jian)的(de)(de)反沖。有(you)一(yi)些(xie)生產商提(ti)供(gong)兩(liang)個(ge)膜(mo)片(pian)(pian)的(de)(de)，也有(you)提(ti)供(gong)三個(ge)膜(mo)片(pian)(pian)的(de)(de)，中間(jian)有(you)一(yi)個(ge)或(huo)兩(liang)個(ge)剛性元件(jian)，兩(liang)邊 再連在軸(zhou)(zhou)(zhou)套(tao)上(shang)。單膜(mo)片(pian)(pian)聯(lian)(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)和(he)(he)(he)雙(shuang)膜(mo)片(pian)(pian)聯(lian)(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)的(de)(de)不(bu)同(tong)(tong)(tong)之(zhi)處是處理(li)各種偏(pian)差能力的(de)(de)不(bu)同(tong)(tong)(tong)，鑒(jian)于(yu)其需要膜(mo)片(pian)(pian)能復(fu)雜的(de)(de)彎曲，所以(yi)單膜(mo)片(pian)(pian)聯(lian)(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)不(bu)太適應偏(pian)心。而雙(shuang)膜(mo)片(pian)(pian)聯(lian)(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)可以(yi)同(tong)(tong)(tong)時曲向(xiang)不(bu)同(tong)(tong)(tong)的(de)(de)方向(xiang)，以(yi)此來補償偏(pian)心。
