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，傳遞扭矩大(da)，使(shi)用壽(shou)命長，免維護，耐高(gao)溫，耐酸堿(jian)防腐蝕，適用于(yu)高(gao)溫高(gao)速及有腐蝕工況環境(jing)的軸系傳動。

膜(mo)片(pian)型聯(lian)軸器(qi)能(neng)補償主動機與從(cong)(cong)動機之(zhi)間由(you)于制造(zao)誤差、安裝誤差、承載變形以及(ji)溫(wen)升變化的影響等(deng)所(suo)引(yin)起的軸向、徑向和(he)角向偏(pian)移(yi)。膜(mo)片(pian)彈性(xing)(xing)聯(lian)軸器(qi)屬金屬彈性(xing)(xing)元件撓性(xing)(xing)聯(lian)軸器(qi)，其依靠(kao)金屬聯(lian)軸器(qi)膜(mo)片(pian)來聯(lian)接(jie)主、從(cong)(cong)動機傳(chuan)遞扭矩，具有(you)彈性(xing)(xing)減(jian)振(zhen)、無噪聲、不需潤滑的優點。

膜(mo)片(pian)(pian)(pian)(pian)聯(lian)軸(zhou)器至(zhi)少由一(yi)個(ge)(ge)(ge)膜(mo)片(pian)(pian)(pian)(pian)和兩(liang)個(ge)(ge)(ge)軸(zhou)套(tao)組(zu)成(cheng)。膜(mo)片(pian)(pian)(pian)(pian)被(bei)用(yong)銷釘(ding)緊固在(zai)(zai)軸(zhou)套(tao)上一(yi)般不(bu)(bu)會松(song)動(dong)或引起膜(mo)片(pian)(pian)(pian)(pian)和軸(zhou)套(tao)之間的反沖(chong)。有(you)(you)一(yi)些生(sheng)產商提(ti)供兩(liang)個(ge)(ge)(ge)膜(mo)片(pian)(pian)(pian)(pian)的，也有(you)(you)提(ti)供三(san)個(ge)(ge)(ge)膜(mo)片(pian)(pian)(pian)(pian)的，中間有(you)(you)一(yi)個(ge)(ge)(ge)或兩(liang)個(ge)(ge)(ge)剛性(xing)元件，兩(liang)邊 再連在(zai)(zai)軸(zhou)套(tao)上。單(dan)膜(mo)片(pian)(pian)(pian)(pian)聯(lian)軸(zhou)器和雙(shuang)(shuang)膜(mo)片(pian)(pian)(pian)(pian)聯(lian)軸(zhou)器的不(bu)(bu)同(tong)之處是處理各(ge)種偏差能力(li)的不(bu)(bu)同(tong)，鑒(jian)于其需要(yao)膜(mo)片(pian)(pian)(pian)(pian)能復(fu)雜的彎曲，所以單(dan)膜(mo)片(pian)(pian)(pian)(pian)聯(lian)軸(zhou)器不(bu)(bu)太適應偏心。而雙(shuang)(shuang)膜(mo)片(pian)(pian)(pian)(pian)聯(lian)軸(zhou)器可(ke)以同(tong)時曲向(xiang)不(bu)(bu)同(tong)的方向(xiang)，以此來補償偏心。
