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)動(dong)(dong)(dong)(dong)(dong)滾(gun)(gun)筒(tong)是帶(dai)式輸送(song)機傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)動(dong)(dong)(dong)(dong)(dong)力的主要(yao)部件(jian)。作(zuo)為單(dan)點驅(qu)動(dong)(dong)(dong)(dong)(dong)方式來(lai)講(jiang)，可分(fen)(fen)成單(dan)滾(gun)(gun)筒(tong)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)及(ji)雙(shuang)滾(gun)(gun)筒(tong)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)。單(dan)滾(gun)(gun)筒(tong)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)多用(yong)(yong)于功率不太大的輸送(song)機上，功率較大的輸送(song)機可采(cai)用(yong)(yong)雙(shuang)滾(gun)(gun)筒(tong)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)，其特點是結(jie)構緊湊，還(huan)可增加圍包角以增加傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)滾(gun)(gun)筒(tong)所能傳(chuan)(chuan)(chuan)(chuan)遞(di)的牽(qian)引力。使用(yong)(yong)雙(shuang)滾(gun)(gun)筒(tong)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)時可以采(cai)用(yong)(yong)多電(dian)機分(fen)(fen)別傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)，可以利用(yong)(yong)齒(chi)輪傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)裝置使兩滾(gun)(gun)筒(tong)同(tong)速(su)運轉。如(ru)雙(shuang)滾(gun)(gun)筒(tong)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)仍不需要(yao)牽(qian)引力需要(yao)，可采(cai)用(yong)(yong)多點驅(qu)動(dong)(dong)(dong)(dong)(dong)方式。
