卷筒聯軸器是一種(zhong)新型(xing)撓性聯(lian)軸(zhou)器(qi)，主要用于(yu)起(qi)重設備(bei)(bei)中起(qi)升機構的減(jian)速器(qi)輸出軸(zhou)與鋼(gang)絲繩卷筒的聯(lian)接，也(ye)適用于(yu)其它類似的既傳(chuan)(chuan)遞轉矩(ju)又承(cheng)(cheng)(cheng)受徑向(xiang)載荷(he)的機械設備(bei)(bei)，但不能用作(zuo)需承(cheng)(cheng)(cheng)受軸(zhou)向(xiang)載荷(he)的傳(chuan)(chuan)動(dong)。卷筒工作(zuo)時產(chan)生的附加軸(zhou)向(xiang)載荷(he)必須由卷筒固定(ding)支承(cheng)(cheng)(cheng)座(zuo)承(cheng)(cheng)(cheng)受，因此，聯(lian)軸(zhou)器(qi)安裝時必須保證軸(zhou)向(xiang)定(ding)位正(zheng)確。否則卷筒工作(zuo)時產(chan)生的彈性水平位移(yi)可(ke)能會破壞聯(lian)軸(zhou)器(qi)的軸(zhou)向(xiang)限(xian)位，造成聯(lian)接失(shi)效，甚至(zhi)釀成嚴重事故。

卷筒聯軸器由(you)(you)帶鼓(gu)形齒(chi)(chi)(chi)的(de)外(wai)齒(chi)(chi)(chi)軸套、帶聯(lian)(lian)接法蘭和內(nei)(nei)齒(chi)(chi)(chi)圈(quan)的(de)外(wai)套、帶外(wai)球面(mian)(mian)的(de)承(cheng)載(zai)(zai)環、端蓋(gai)和密封(feng)圈(quan)等(deng)組(zu)成(cheng)(cheng)(cheng)，并設有定位磨損指(zhi)針、潤滑油(you)孔(kong)和通(tong)氣孔(kong)等(deng)。外(wai)齒(chi)(chi)(chi)軸套和外(wai)套構成(cheng)(cheng)(cheng)的(de)鼓(gu)形齒(chi)(chi)(chi)式聯(lian)(lian)軸器傳遞驅動(dong)功率, 而由(you)(you)承(cheng)載(zai)(zai)環的(de)外(wai)球面(mian)(mian)和外(wai)套的(de)內(nei)(nei)承(cheng)載(zai)(zai)面(mian)(mian)形成(cheng)(cheng)(cheng)的(de)接觸(chu)副(fu)構成(cheng)(cheng)(cheng)自(zi)動(dong)調位的(de)球面(mian)(mian)軸承(cheng)，承(cheng)受徑(jing)向載(zai)(zai)荷。卷筒用聯(lian)(lian)軸器的(de)內(nei)(nei)、外(wai)齒(chi)(chi)(chi)嚙合在油(you)浴中工(gong)作,通(tong)過內(nei)(nei)外(wai)端蓋(gai)、密封(feng)圈(quan)防止潤滑脂泄漏。
