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(jin)湊，傳遞扭(niu)矩大，使用壽命長，免維護(hu)，耐高溫，耐酸(suan)堿防腐蝕，適用于高溫高速及有腐蝕工況環境的軸系(xi)傳動。

膜(mo)片(pian)型聯(lian)軸(zhou)(zhou)器能補償主(zhu)(zhu)動(dong)機與從動(dong)機之間由(you)于制造誤(wu)差(cha)、安裝誤(wu)差(cha)、承載變形以及溫(wen)升變化的影響等(deng)所引起的軸(zhou)(zhou)向(xiang)(xiang)、徑(jing)向(xiang)(xiang)和角(jiao)向(xiang)(xiang)偏移。膜(mo)片(pian)彈(dan)性(xing)聯(lian)軸(zhou)(zhou)器屬金屬彈(dan)性(xing)元(yuan)件撓性(xing)聯(lian)軸(zhou)(zhou)器，其(qi)依靠金屬聯(lian)軸(zhou)(zhou)器膜(mo)片(pian)來聯(lian)接主(zhu)(zhu)、從動(dong)機傳遞扭矩(ju)，具有彈(dan)性(xing)減振(zhen)、無噪(zao)聲(sheng)、不(bu)需潤滑的優點。

膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)聯軸(zhou)(zhou)器(qi)至(zhi)少由一(yi)個(ge)膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)和兩(liang)個(ge)軸(zhou)(zhou)套(tao)組(zu)成。膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)被用銷釘緊固(gu)在(zai)軸(zhou)(zhou)套(tao)上一(yi)般不會松(song)動或引起(qi)膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)和軸(zhou)(zhou)套(tao)之間的反沖。有一(yi)些生產商提(ti)供兩(liang)個(ge)膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)的，也有提(ti)供三(san)個(ge)膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)的，中(zhong)間有一(yi)個(ge)或兩(liang)個(ge)剛(gang)性(xing)元件，兩(liang)邊 再(zai)連在(zai)軸(zhou)(zhou)套(tao)上。單(dan)膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)聯軸(zhou)(zhou)器(qi)和雙膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)聯軸(zhou)(zhou)器(qi)的不同之處(chu)是處(chu)理各種偏(pian)差能(neng)力的不同，鑒于其(qi)需(xu)要膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)能(neng)復雜的彎曲，所以(yi)單(dan)膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)聯軸(zhou)(zhou)器(qi)不太適應偏(pian)心。而雙膜(mo)(mo)(mo)片(pian)(pian)(pian)(pian)(pian)聯軸(zhou)(zhou)器(qi)可以(yi)同時曲向不同的方(fang)向，以(yi)此來補償偏(pian)心。
