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(chuan)(chuan)遞扭(niu)矩(ju)大，使用(yong)壽(shou)命長，免維護，耐高溫(wen)，耐酸(suan)堿防腐(fu)蝕，適用(yong)于高溫(wen)高速及有腐(fu)蝕工況環境(jing)的軸系傳(chuan)(chuan)動。

膜片型(xing)聯(lian)(lian)軸器能補償主(zhu)動機(ji)與從動機(ji)之(zhi)間由于(yu)制造誤(wu)差、安裝誤(wu)差、承載變形以及(ji)溫升變化的影響等所(suo)引起的軸向(xiang)、徑向(xiang)和角向(xiang)偏移。膜片彈(dan)性(xing)(xing)聯(lian)(lian)軸器屬金(jin)屬彈(dan)性(xing)(xing)元件撓性(xing)(xing)聯(lian)(lian)軸器，其(qi)依靠(kao)金(jin)屬聯(lian)(lian)軸器膜片來聯(lian)(lian)接(jie)主(zhu)、從動機(ji)傳遞(di)扭(niu)矩，具有彈(dan)性(xing)(xing)減振、無噪聲、不需潤滑的優(you)點。

膜(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)器(qi)至少(shao)由一(yi)個膜(mo)片(pian)(pian)(pian)(pian)和兩個軸(zhou)套組(zu)成。膜(mo)片(pian)(pian)(pian)(pian)被用銷(xiao)釘緊固在軸(zhou)套上一(yi)般(ban)不會松動或引(yin)起膜(mo)片(pian)(pian)(pian)(pian)和軸(zhou)套之(zhi)間的(de)反沖(chong)。有(you)一(yi)些生(sheng)產商(shang)提(ti)供兩個膜(mo)片(pian)(pian)(pian)(pian)的(de)，也有(you)提(ti)供三個膜(mo)片(pian)(pian)(pian)(pian)的(de)，中間有(you)一(yi)個或兩個剛性元件，兩邊 再連(lian)在軸(zhou)套上。單膜(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)器(qi)和雙膜(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)器(qi)的(de)不同(tong)(tong)之(zhi)處(chu)是處(chu)理各種偏差能(neng)力(li)的(de)不同(tong)(tong)，鑒于其需要膜(mo)片(pian)(pian)(pian)(pian)能(neng)復雜的(de)彎曲，所(suo)以單膜(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)器(qi)不太適應偏心。而(er)雙膜(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)器(qi)可以同(tong)(tong)時曲向(xiang)不同(tong)(tong)的(de)方向(xiang)，以此來補(bu)償偏心。
