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，傳遞扭矩(ju)大，使用壽命長，免維護，耐高(gao)溫(wen)，耐酸堿防腐(fu)蝕，適用于高(gao)溫(wen)高(gao)速及有腐(fu)蝕工況環境(jing)的軸系傳動。

膜片型聯(lian)軸(zhou)(zhou)器(qi)(qi)(qi)能補(bu)償(chang)主動(dong)(dong)(dong)機與從動(dong)(dong)(dong)機之間由于制(zhi)造誤差、安裝誤差、承(cheng)載變形以(yi)及溫升變化的影(ying)響等所(suo)引起的軸(zhou)(zhou)向、徑(jing)向和(he)角向偏移。膜片彈(dan)性聯(lian)軸(zhou)(zhou)器(qi)(qi)(qi)屬(shu)金屬(shu)彈(dan)性元(yuan)件撓性聯(lian)軸(zhou)(zhou)器(qi)(qi)(qi)，其依靠(kao)金屬(shu)聯(lian)軸(zhou)(zhou)器(qi)(qi)(qi)膜片來聯(lian)接主、從動(dong)(dong)(dong)機傳遞扭矩，具(ju)有(you)彈(dan)性減振、無噪聲、不需(xu)潤滑的優點。

膜(mo)片(pian)(pian)聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)至(zhi)少由一個(ge)(ge)膜(mo)片(pian)(pian)和兩(liang)(liang)個(ge)(ge)軸(zhou)(zhou)套(tao)組成。膜(mo)片(pian)(pian)被用銷釘(ding)緊固在(zai)(zai)軸(zhou)(zhou)套(tao)上(shang)(shang)一般不會松動或(huo)引起(qi)膜(mo)片(pian)(pian)和軸(zhou)(zhou)套(tao)之(zhi)(zhi)間(jian)(jian)的(de)(de)反沖。有一些生(sheng)產商(shang)提(ti)供(gong)兩(liang)(liang)個(ge)(ge)膜(mo)片(pian)(pian)的(de)(de)，也有提(ti)供(gong)三個(ge)(ge)膜(mo)片(pian)(pian)的(de)(de)，中間(jian)(jian)有一個(ge)(ge)或(huo)兩(liang)(liang)個(ge)(ge)剛(gang)性元件，兩(liang)(liang)邊 再連在(zai)(zai)軸(zhou)(zhou)套(tao)上(shang)(shang)。單(dan)膜(mo)片(pian)(pian)聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)和雙(shuang)膜(mo)片(pian)(pian)聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)的(de)(de)不同(tong)(tong)之(zhi)(zhi)處是處理各(ge)種偏(pian)差能力的(de)(de)不同(tong)(tong)，鑒于其需(xu)要(yao)膜(mo)片(pian)(pian)能復雜的(de)(de)彎(wan)曲(qu)(qu)，所以單(dan)膜(mo)片(pian)(pian)聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)不太適應偏(pian)心。而雙(shuang)膜(mo)片(pian)(pian)聯(lian)(lian)(lian)軸(zhou)(zhou)器(qi)可以同(tong)(tong)時曲(qu)(qu)向不同(tong)(tong)的(de)(de)方向，以此來補償偏(pian)心。
