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)動(dong)滾(gun)(gun)筒(tong)是帶式(shi)輸(shu)送機(ji)(ji)傳(chuan)(chuan)動(dong)動(dong)力(li)的(de)主(zhu)要(yao)(yao)部件。作(zuo)為(wei)單(dan)(dan)點驅(qu)動(dong)方式(shi)來(lai)講，可(ke)(ke)分(fen)成單(dan)(dan)滾(gun)(gun)筒(tong)傳(chuan)(chuan)動(dong)及雙(shuang)(shuang)滾(gun)(gun)筒(tong)傳(chuan)(chuan)動(dong)。單(dan)(dan)滾(gun)(gun)筒(tong)傳(chuan)(chuan)動(dong)多用于(yu)功(gong)率不(bu)太(tai)大的(de)輸(shu)送機(ji)(ji)上，功(gong)率較(jiao)大的(de)輸(shu)送機(ji)(ji)可(ke)(ke)采(cai)用雙(shuang)(shuang)滾(gun)(gun)筒(tong)傳(chuan)(chuan)動(dong)，其特點是結構(gou)緊湊，還(huan)可(ke)(ke)增加圍包角(jiao)以增加傳(chuan)(chuan)動(dong)滾(gun)(gun)筒(tong)所能傳(chuan)(chuan)遞的(de)牽引力(li)。使用雙(shuang)(shuang)滾(gun)(gun)筒(tong)傳(chuan)(chuan)動(dong)時可(ke)(ke)以采(cai)用多電機(ji)(ji)分(fen)別傳(chuan)(chuan)動(dong)，可(ke)(ke)以利(li)用齒輪(lun)傳(chuan)(chuan)動(dong)裝置使兩(liang)滾(gun)(gun)筒(tong)同速運(yun)轉。如雙(shuang)(shuang)滾(gun)(gun)筒(tong)傳(chuan)(chuan)動(dong)仍不(bu)需要(yao)(yao)牽引力(li)需要(yao)(yao)，可(ke)(ke)采(cai)用多點驅(qu)動(dong)方式(shi)。
