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)滾(gun)(gun)(gun)筒(tong)(tong)(tong)是帶(dai)式(shi)輸送機傳(chuan)(chuan)(chuan)(chuan)動(dong)動(dong)力(li)的主要部件(jian)。作為單(dan)點(dian)驅(qu)動(dong)方式(shi)來講(jiang)，可(ke)分(fen)(fen)成單(dan)滾(gun)(gun)(gun)筒(tong)(tong)(tong)傳(chuan)(chuan)(chuan)(chuan)動(dong)及雙(shuang)滾(gun)(gun)(gun)筒(tong)(tong)(tong)傳(chuan)(chuan)(chuan)(chuan)動(dong)。單(dan)滾(gun)(gun)(gun)筒(tong)(tong)(tong)傳(chuan)(chuan)(chuan)(chuan)動(dong)多(duo)用(yong)于(yu)功(gong)率不太大的輸送機上，功(gong)率較大的輸送機可(ke)采用(yong)雙(shuang)滾(gun)(gun)(gun)筒(tong)(tong)(tong)傳(chuan)(chuan)(chuan)(chuan)動(dong)，其特(te)點(dian)是結構緊湊，還可(ke)增加圍(wei)包角以增加傳(chuan)(chuan)(chuan)(chuan)動(dong)滾(gun)(gun)(gun)筒(tong)(tong)(tong)所能傳(chuan)(chuan)(chuan)(chuan)遞(di)的牽(qian)引(yin)力(li)。使用(yong)雙(shuang)滾(gun)(gun)(gun)筒(tong)(tong)(tong)傳(chuan)(chuan)(chuan)(chuan)動(dong)時可(ke)以采用(yong)多(duo)電(dian)機分(fen)(fen)別傳(chuan)(chuan)(chuan)(chuan)動(dong)，可(ke)以利用(yong)齒輪傳(chuan)(chuan)(chuan)(chuan)動(dong)裝(zhuang)置(zhi)使兩滾(gun)(gun)(gun)筒(tong)(tong)(tong)同速運轉。如雙(shuang)滾(gun)(gun)(gun)筒(tong)(tong)(tong)傳(chuan)(chuan)(chuan)(chuan)動(dong)仍不需(xu)要牽(qian)引(yin)力(li)需(xu)要，可(ke)采用(yong)多(duo)點(dian)驅(qu)動(dong)方式(shi)。
