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(jie)構(gou)緊湊，傳遞扭矩大(da)，使(shi)用(yong)壽(shou)命長(chang)，免維(wei)護，耐高(gao)溫(wen)，耐酸堿防腐蝕(shi)，適用(yong)于高(gao)溫(wen)高(gao)速及(ji)有腐蝕(shi)工況環境的軸系傳動。

膜(mo)片型聯軸(zhou)器(qi)能補(bu)償主(zhu)動機與從動機之(zhi)間由于制造誤差、安(an)裝(zhuang)誤差、承載變形以及(ji)溫升變化的影響等所引(yin)起的軸(zhou)向(xiang)(xiang)、徑向(xiang)(xiang)和角向(xiang)(xiang)偏移。膜(mo)片彈(dan)性(xing)聯軸(zhou)器(qi)屬(shu)金屬(shu)彈(dan)性(xing)元件撓性(xing)聯軸(zhou)器(qi)，其依靠金屬(shu)聯軸(zhou)器(qi)膜(mo)片來聯接主(zhu)、從動機傳遞扭矩，具有(you)彈(dan)性(xing)減振、無噪聲(sheng)、不需潤(run)滑的優點。

膜片(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)器(qi)至少由一(yi)個(ge)膜片(pian)(pian)(pian)(pian)和兩(liang)個(ge)軸(zhou)套組成。膜片(pian)(pian)(pian)(pian)被(bei)用銷釘緊(jin)固在軸(zhou)套上一(yi)般不(bu)(bu)會松動或引(yin)起(qi)膜片(pian)(pian)(pian)(pian)和軸(zhou)套之間的(de)反(fan)沖。有(you)一(yi)些生產商(shang)提(ti)供兩(liang)個(ge)膜片(pian)(pian)(pian)(pian)的(de)，也有(you)提(ti)供三(san)個(ge)膜片(pian)(pian)(pian)(pian)的(de)，中(zhong)間有(you)一(yi)個(ge)或兩(liang)個(ge)剛性(xing)元(yuan)件，兩(liang)邊 再連在軸(zhou)套上。單膜片(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)器(qi)和雙膜片(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)器(qi)的(de)不(bu)(bu)同(tong)(tong)之處(chu)是處(chu)理各種偏(pian)差(cha)能力的(de)不(bu)(bu)同(tong)(tong)，鑒于其(qi)需要膜片(pian)(pian)(pian)(pian)能復雜(za)的(de)彎曲，所以(yi)單膜片(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)器(qi)不(bu)(bu)太適(shi)應偏(pian)心(xin)。而雙膜片(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)器(qi)可以(yi)同(tong)(tong)時曲向不(bu)(bu)同(tong)(tong)的(de)方向，以(yi)此來補償偏(pian)心(xin)。
