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)動(dong)(dong)(dong)滾(gun)(gun)(gun)筒(tong)(tong)(tong)是帶式輸送(song)機傳(chuan)動(dong)(dong)(dong)動(dong)(dong)(dong)力的主要部件。作為單點驅(qu)動(dong)(dong)(dong)方式來講(jiang)，可(ke)(ke)分(fen)成(cheng)單滾(gun)(gun)(gun)筒(tong)(tong)(tong)傳(chuan)動(dong)(dong)(dong)及(ji)雙滾(gun)(gun)(gun)筒(tong)(tong)(tong)傳(chuan)動(dong)(dong)(dong)。單滾(gun)(gun)(gun)筒(tong)(tong)(tong)傳(chuan)動(dong)(dong)(dong)多(duo)用(yong)于功率不(bu)太大(da)的輸送(song)機上，功率較(jiao)大(da)的輸送(song)機可(ke)(ke)采(cai)用(yong)雙滾(gun)(gun)(gun)筒(tong)(tong)(tong)傳(chuan)動(dong)(dong)(dong)，其(qi)特點是結構緊湊，還可(ke)(ke)增加圍包(bao)角(jiao)以增加傳(chuan)動(dong)(dong)(dong)滾(gun)(gun)(gun)筒(tong)(tong)(tong)所能傳(chuan)遞的牽引力。使用(yong)雙滾(gun)(gun)(gun)筒(tong)(tong)(tong)傳(chuan)動(dong)(dong)(dong)時可(ke)(ke)以采(cai)用(yong)多(duo)電機分(fen)別傳(chuan)動(dong)(dong)(dong)，可(ke)(ke)以利(li)用(yong)齒輪(lun)傳(chuan)動(dong)(dong)(dong)裝置使兩滾(gun)(gun)(gun)筒(tong)(tong)(tong)同速(su)運(yun)轉。如雙滾(gun)(gun)(gun)筒(tong)(tong)(tong)傳(chuan)動(dong)(dong)(dong)仍不(bu)需要牽引力需要，可(ke)(ke)采(cai)用(yong)多(duo)點驅(qu)動(dong)(dong)(dong)方式。
