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(jin)湊，傳遞扭矩(ju)大，使(shi)用壽(shou)命(ming)長，免維護，耐高(gao)(gao)溫，耐酸堿防腐蝕，適(shi)用于高(gao)(gao)溫高(gao)(gao)速及(ji)有腐蝕工況(kuang)環境的軸系傳動。

膜片型聯(lian)(lian)(lian)軸器(qi)能補(bu)償主動(dong)機(ji)(ji)與從動(dong)機(ji)(ji)之間由于(yu)制造誤差(cha)、安裝(zhuang)誤差(cha)、承(cheng)載變形以及溫升變化的影響(xiang)等(deng)所引起的軸向、徑(jing)向和(he)角向偏移。膜片彈性(xing)(xing)聯(lian)(lian)(lian)軸器(qi)屬(shu)金屬(shu)彈性(xing)(xing)元件(jian)撓性(xing)(xing)聯(lian)(lian)(lian)軸器(qi)，其(qi)依靠(kao)金屬(shu)聯(lian)(lian)(lian)軸器(qi)膜片來聯(lian)(lian)(lian)接(jie)主、從動(dong)機(ji)(ji)傳遞(di)扭矩，具有(you)彈性(xing)(xing)減(jian)振、無噪聲、不需(xu)潤滑的優(you)點。

膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)(pian)聯(lian)軸器至(zhi)少由一(yi)個膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)(pian)和(he)兩(liang)個軸套(tao)(tao)組成。膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)(pian)被(bei)用(yong)銷(xiao)釘緊固在(zai)(zai)軸套(tao)(tao)上一(yi)般(ban)不會松動或(huo)引起膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)(pian)和(he)軸套(tao)(tao)之間(jian)的(de)(de)(de)(de)反沖(chong)。有一(yi)些生產商(shang)提(ti)供(gong)兩(liang)個膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)(pian)的(de)(de)(de)(de)，也有提(ti)供(gong)三個膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)(pian)的(de)(de)(de)(de)，中(zhong)間(jian)有一(yi)個或(huo)兩(liang)個剛性(xing)元件，兩(liang)邊 再連在(zai)(zai)軸套(tao)(tao)上。單(dan)膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)(pian)聯(lian)軸器和(he)雙膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)(pian)聯(lian)軸器的(de)(de)(de)(de)不同之處是處理各種偏差能(neng)力的(de)(de)(de)(de)不同，鑒于其需要膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)(pian)能(neng)復雜的(de)(de)(de)(de)彎曲(qu)，所以單(dan)膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)(pian)聯(lian)軸器不太(tai)適應偏心。而雙膜(mo)(mo)片(pian)(pian)(pian)(pian)(pian)(pian)聯(lian)軸器可以同時曲(qu)向不同的(de)(de)(de)(de)方向，以此來補(bu)償偏心。
