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)筒是帶式輸(shu)送(song)(song)機(ji)傳(chuan)(chuan)動(dong)動(dong)力(li)的(de)(de)主(zhu)要部件(jian)。作(zuo)為(wei)單(dan)點(dian)驅(qu)動(dong)方式來講(jiang)，可分成單(dan)滾(gun)(gun)筒傳(chuan)(chuan)動(dong)及雙滾(gun)(gun)筒傳(chuan)(chuan)動(dong)。單(dan)滾(gun)(gun)筒傳(chuan)(chuan)動(dong)多用(yong)于(yu)功率(lv)不太大的(de)(de)輸(shu)送(song)(song)機(ji)上，功率(lv)較大的(de)(de)輸(shu)送(song)(song)機(ji)可采用(yong)雙滾(gun)(gun)筒傳(chuan)(chuan)動(dong)，其特點(dian)是結(jie)構緊(jin)湊，還可增加圍包角以(yi)增加傳(chuan)(chuan)動(dong)滾(gun)(gun)筒所能(neng)傳(chuan)(chuan)遞的(de)(de)牽(qian)引力(li)。使用(yong)雙滾(gun)(gun)筒傳(chuan)(chuan)動(dong)時可以(yi)采用(yong)多電機(ji)分別傳(chuan)(chuan)動(dong)，可以(yi)利(li)用(yong)齒輪傳(chuan)(chuan)動(dong)裝置使兩(liang)滾(gun)(gun)筒同(tong)速運轉。如雙滾(gun)(gun)筒傳(chuan)(chuan)動(dong)仍不需要牽(qian)引力(li)需要，可采用(yong)多點(dian)驅(qu)動(dong)方式。
