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(jin)湊，傳遞扭(niu)矩(ju)大(da)，使(shi)用(yong)壽(shou)命(ming)長，免維護，耐高(gao)溫，耐酸堿防腐蝕，適用(yong)于高(gao)溫高(gao)速及有腐蝕工況環境的軸系傳動。

膜片型聯(lian)軸(zhou)器(qi)(qi)能補償主(zhu)動(dong)機(ji)與從動(dong)機(ji)之間由于制造(zao)誤差、安裝誤差、承載變形以及溫升變化的(de)影(ying)響(xiang)等所引起的(de)軸(zhou)向(xiang)、徑(jing)向(xiang)和角向(xiang)偏移。膜片彈性(xing)聯(lian)軸(zhou)器(qi)(qi)屬金屬彈性(xing)元(yuan)件(jian)撓性(xing)聯(lian)軸(zhou)器(qi)(qi)，其依(yi)靠金屬聯(lian)軸(zhou)器(qi)(qi)膜片來聯(lian)接主(zhu)、從動(dong)機(ji)傳遞扭矩，具有彈性(xing)減(jian)振(zhen)、無噪聲(sheng)、不需潤滑的(de)優點。

膜(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)至少由一(yi)個(ge)(ge)膜(mo)(mo)片(pian)(pian)(pian)(pian)和(he)兩個(ge)(ge)軸(zhou)(zhou)(zhou)套(tao)(tao)組成。膜(mo)(mo)片(pian)(pian)(pian)(pian)被用銷釘緊固在軸(zhou)(zhou)(zhou)套(tao)(tao)上一(yi)般(ban)不(bu)會松動或引(yin)起膜(mo)(mo)片(pian)(pian)(pian)(pian)和(he)軸(zhou)(zhou)(zhou)套(tao)(tao)之間(jian)的(de)反沖。有一(yi)些生產商提供(gong)兩個(ge)(ge)膜(mo)(mo)片(pian)(pian)(pian)(pian)的(de)，也有提供(gong)三(san)個(ge)(ge)膜(mo)(mo)片(pian)(pian)(pian)(pian)的(de)，中間(jian)有一(yi)個(ge)(ge)或兩個(ge)(ge)剛性元(yuan)件，兩邊 再連(lian)在軸(zhou)(zhou)(zhou)套(tao)(tao)上。單膜(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)和(he)雙(shuang)膜(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)的(de)不(bu)同(tong)之處是處理(li)各種偏差(cha)能力的(de)不(bu)同(tong)，鑒于其(qi)需要膜(mo)(mo)片(pian)(pian)(pian)(pian)能復雜的(de)彎曲，所以單膜(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)不(bu)太適應偏心(xin)。而雙(shuang)膜(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)(zhou)器(qi)(qi)可以同(tong)時曲向(xiang)不(bu)同(tong)的(de)方向(xiang)，以此來補(bu)償偏心(xin)。
