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)構緊湊，傳遞(di)扭矩大，使用壽(shou)命長，免維護，耐高溫，耐酸堿防腐蝕(shi)，適(shi)用于(yu)高溫高速(su)及有腐蝕(shi)工況環境的(de)軸系傳動。

膜片型聯軸器(qi)(qi)能補償主動(dong)機(ji)與從動(dong)機(ji)之間由于制造誤差(cha)(cha)、安裝誤差(cha)(cha)、承載變(bian)形以及溫升變(bian)化的(de)影響等所引起(qi)的(de)軸向、徑向和角(jiao)向偏移。膜片彈(dan)性(xing)(xing)聯軸器(qi)(qi)屬(shu)金屬(shu)彈(dan)性(xing)(xing)元件撓性(xing)(xing)聯軸器(qi)(qi)，其(qi)依靠金屬(shu)聯軸器(qi)(qi)膜片來聯接(jie)主、從動(dong)機(ji)傳遞扭(niu)矩，具(ju)有(you)彈(dan)性(xing)(xing)減(jian)振(zhen)、無噪聲、不需(xu)潤滑(hua)的(de)優點。

膜片(pian)(pian)(pian)(pian)聯(lian)軸(zhou)器(qi)(qi)至少由一(yi)個(ge)膜片(pian)(pian)(pian)(pian)和(he)兩個(ge)軸(zhou)套(tao)組成(cheng)。膜片(pian)(pian)(pian)(pian)被(bei)用銷釘(ding)緊固(gu)在軸(zhou)套(tao)上(shang)(shang)一(yi)般不(bu)會松動或(huo)引(yin)起膜片(pian)(pian)(pian)(pian)和(he)軸(zhou)套(tao)之(zhi)間(jian)的反(fan)沖(chong)。有(you)一(yi)些生產商提供兩個(ge)膜片(pian)(pian)(pian)(pian)的，也(ye)有(you)提供三個(ge)膜片(pian)(pian)(pian)(pian)的，中間(jian)有(you)一(yi)個(ge)或(huo)兩個(ge)剛(gang)性元件，兩邊 再連在軸(zhou)套(tao)上(shang)(shang)。單(dan)膜片(pian)(pian)(pian)(pian)聯(lian)軸(zhou)器(qi)(qi)和(he)雙膜片(pian)(pian)(pian)(pian)聯(lian)軸(zhou)器(qi)(qi)的不(bu)同之(zhi)處(chu)是處(chu)理各種偏差(cha)能(neng)力的不(bu)同，鑒于其需要膜片(pian)(pian)(pian)(pian)能(neng)復雜(za)的彎曲(qu)，所(suo)以單(dan)膜片(pian)(pian)(pian)(pian)聯(lian)軸(zhou)器(qi)(qi)不(bu)太(tai)適應偏心。而雙膜片(pian)(pian)(pian)(pian)聯(lian)軸(zhou)器(qi)(qi)可以同時(shi)曲(qu)向(xiang)(xiang)不(bu)同的方向(xiang)(xiang)，以此來補償偏心。
