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湊，傳遞扭矩(ju)大，使(shi)用(yong)(yong)壽(shou)命長，免(mian)維(wei)護，耐高(gao)溫，耐酸堿(jian)防腐(fu)蝕，適用(yong)(yong)于高(gao)溫高(gao)速(su)及(ji)有腐(fu)蝕工(gong)況環境(jing)的軸(zhou)系傳動。

膜(mo)片型聯(lian)(lian)軸器能補(bu)償主動機(ji)(ji)與從(cong)動機(ji)(ji)之間由于(yu)制(zhi)造誤(wu)差、安(an)裝誤(wu)差、承載變形以及溫升變化的影響等所引起(qi)的軸向(xiang)、徑向(xiang)和(he)角向(xiang)偏(pian)移。膜(mo)片彈性(xing)(xing)聯(lian)(lian)軸器屬金屬彈性(xing)(xing)元件撓性(xing)(xing)聯(lian)(lian)軸器，其依(yi)靠金屬聯(lian)(lian)軸器膜(mo)片來聯(lian)(lian)接主、從(cong)動機(ji)(ji)傳遞扭矩，具(ju)有彈性(xing)(xing)減振(zhen)、無噪聲(sheng)、不需潤滑的優(you)點(dian)。

膜(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)器(qi)(qi)至少由一(yi)個膜(mo)(mo)片(pian)(pian)(pian)(pian)和兩個軸(zhou)(zhou)套組成。膜(mo)(mo)片(pian)(pian)(pian)(pian)被用銷釘緊固(gu)在(zai)軸(zhou)(zhou)套上一(yi)般不(bu)(bu)會松(song)動或(huo)引起膜(mo)(mo)片(pian)(pian)(pian)(pian)和軸(zhou)(zhou)套之間的(de)反沖。有一(yi)些生產商(shang)提供兩個膜(mo)(mo)片(pian)(pian)(pian)(pian)的(de)，也有提供三個膜(mo)(mo)片(pian)(pian)(pian)(pian)的(de)，中間有一(yi)個或(huo)兩個剛性元(yuan)件(jian)，兩邊 再連在(zai)軸(zhou)(zhou)套上。單(dan)膜(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)器(qi)(qi)和雙(shuang)膜(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)器(qi)(qi)的(de)不(bu)(bu)同之處(chu)是處(chu)理(li)各種偏差能力的(de)不(bu)(bu)同，鑒于(yu)其需要(yao)膜(mo)(mo)片(pian)(pian)(pian)(pian)能復雜的(de)彎(wan)曲，所以(yi)單(dan)膜(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)器(qi)(qi)不(bu)(bu)太適(shi)應偏心。而雙(shuang)膜(mo)(mo)片(pian)(pian)(pian)(pian)聯(lian)(lian)軸(zhou)(zhou)器(qi)(qi)可以(yi)同時(shi)曲向不(bu)(bu)同的(de)方(fang)向，以(yi)此來(lai)補償偏心。
