傳動滾筒是傳遞動力的重要部件，滾筒有光面、膠面。膠面形狀又可分成光面膠，人字膠及菱形膠，以適應不同工藝需求。

傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)滾(gun)筒(tong)(tong)(tong)是(shi)帶式(shi)輸送(song)機(ji)(ji)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)動(dong)(dong)(dong)(dong)(dong)力的(de)主要(yao)部(bu)件(jian)。作(zuo)為單(dan)(dan)點驅動(dong)(dong)(dong)(dong)(dong)方(fang)式(shi)來講(jiang)，可(ke)分(fen)成單(dan)(dan)滾(gun)筒(tong)(tong)(tong)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)及雙(shuang)(shuang)滾(gun)筒(tong)(tong)(tong)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)。單(dan)(dan)滾(gun)筒(tong)(tong)(tong)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)多用(yong)于功率不太(tai)大的(de)輸送(song)機(ji)(ji)上，功率較(jiao)大的(de)輸送(song)機(ji)(ji)可(ke)采用(yong)雙(shuang)(shuang)滾(gun)筒(tong)(tong)(tong)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)，其特點是(shi)結構緊湊，還可(ke)增加(jia)圍包角(jiao)以增加(jia)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)滾(gun)筒(tong)(tong)(tong)所能傳(chuan)(chuan)(chuan)(chuan)(chuan)遞的(de)牽引力。使用(yong)雙(shuang)(shuang)滾(gun)筒(tong)(tong)(tong)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)時可(ke)以采用(yong)多電機(ji)(ji)分(fen)別傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)，可(ke)以利用(yong)齒輪傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)裝(zhuang)置使兩滾(gun)筒(tong)(tong)(tong)同速運(yun)轉。如(ru)雙(shuang)(shuang)滾(gun)筒(tong)(tong)(tong)傳(chuan)(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)仍不需要(yao)牽引力需要(yao)，可(ke)采用(yong)多點驅動(dong)(dong)(dong)(dong)(dong)方(fang)式(shi)。
