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)滾(gun)(gun)筒(tong)(tong)(tong)是(shi)帶式輸送(song)機(ji)傳(chuan)動(dong)動(dong)力的(de)主要(yao)(yao)部件。作為單(dan)(dan)點(dian)驅(qu)動(dong)方式來講(jiang)，可分成單(dan)(dan)滾(gun)(gun)筒(tong)(tong)(tong)傳(chuan)動(dong)及雙(shuang)滾(gun)(gun)筒(tong)(tong)(tong)傳(chuan)動(dong)。單(dan)(dan)滾(gun)(gun)筒(tong)(tong)(tong)傳(chuan)動(dong)多用(yong)于(yu)功率(lv)不太大(da)的(de)輸送(song)機(ji)上(shang)，功率(lv)較大(da)的(de)輸送(song)機(ji)可采(cai)用(yong)雙(shuang)滾(gun)(gun)筒(tong)(tong)(tong)傳(chuan)動(dong)，其特點(dian)是(shi)結構緊(jin)湊(cou)，還可增加(jia)圍包角(jiao)以增加(jia)傳(chuan)動(dong)滾(gun)(gun)筒(tong)(tong)(tong)所能(neng)傳(chuan)遞的(de)牽(qian)引(yin)力。使用(yong)雙(shuang)滾(gun)(gun)筒(tong)(tong)(tong)傳(chuan)動(dong)時可以采(cai)用(yong)多電機(ji)分別(bie)傳(chuan)動(dong)，可以利用(yong)齒輪傳(chuan)動(dong)裝置使兩(liang)滾(gun)(gun)筒(tong)(tong)(tong)同速運轉。如雙(shuang)滾(gun)(gun)筒(tong)(tong)(tong)傳(chuan)動(dong)仍(reng)不需要(yao)(yao)牽(qian)引(yin)力需要(yao)(yao)，可采(cai)用(yong)多點(dian)驅(qu)動(dong)方式。
