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

膜片型聯(lian)(lian)軸器(qi)(qi)能補償主動(dong)(dong)機(ji)與(yu)從動(dong)(dong)機(ji)之(zhi)間由(you)于(yu)制造誤差(cha)、安(an)裝(zhuang)誤差(cha)、承載變(bian)(bian)形以及溫升變(bian)(bian)化的影響等所(suo)引起(qi)的軸向、徑向和角向偏移。膜片彈(dan)性聯(lian)(lian)軸器(qi)(qi)屬(shu)金屬(shu)彈(dan)性元件撓性聯(lian)(lian)軸器(qi)(qi)，其依(yi)靠金屬(shu)聯(lian)(lian)軸器(qi)(qi)膜片來聯(lian)(lian)接(jie)主、從動(dong)(dong)機(ji)傳(chuan)遞扭矩，具有(you)彈(dan)性減振、無噪聲、不需潤滑(hua)的優點。

膜(mo)片(pian)(pian)聯軸器至少由一(yi)個(ge)(ge)膜(mo)片(pian)(pian)和兩(liang)(liang)個(ge)(ge)軸套(tao)(tao)組成(cheng)。膜(mo)片(pian)(pian)被用銷(xiao)釘緊固(gu)在軸套(tao)(tao)上(shang)一(yi)般不(bu)會(hui)松動或引起膜(mo)片(pian)(pian)和軸套(tao)(tao)之間的(de)反沖。有(you)一(yi)些(xie)生產商提(ti)供(gong)兩(liang)(liang)個(ge)(ge)膜(mo)片(pian)(pian)的(de)，也有(you)提(ti)供(gong)三個(ge)(ge)膜(mo)片(pian)(pian)的(de)，中(zhong)間有(you)一(yi)個(ge)(ge)或兩(liang)(liang)個(ge)(ge)剛性元(yuan)件，兩(liang)(liang)邊(bian) 再(zai)連在軸套(tao)(tao)上(shang)。單膜(mo)片(pian)(pian)聯軸器和雙(shuang)膜(mo)片(pian)(pian)聯軸器的(de)不(bu)同(tong)(tong)之處(chu)是處(chu)理(li)各(ge)種(zhong)偏差能力(li)的(de)不(bu)同(tong)(tong)，鑒于其需要(yao)膜(mo)片(pian)(pian)能復雜(za)的(de)彎曲，所以單膜(mo)片(pian)(pian)聯軸器不(bu)太適應偏心(xin)。而雙(shuang)膜(mo)片(pian)(pian)聯軸器可(ke)以同(tong)(tong)時曲向不(bu)同(tong)(tong)的(de)方向，以此來補(bu)償偏心(xin)。
