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)滾筒(tong)是(shi)帶(dai)式(shi)輸(shu)送機(ji)(ji)傳(chuan)動(dong)(dong)動(dong)(dong)力(li)的(de)主(zhu)要(yao)部件。作為單(dan)點驅(qu)動(dong)(dong)方式(shi)來講，可(ke)分成單(dan)滾筒(tong)傳(chuan)動(dong)(dong)及雙(shuang)(shuang)滾筒(tong)傳(chuan)動(dong)(dong)。單(dan)滾筒(tong)傳(chuan)動(dong)(dong)多(duo)用(yong)(yong)(yong)于功(gong)率不太大(da)的(de)輸(shu)送機(ji)(ji)上，功(gong)率較大(da)的(de)輸(shu)送機(ji)(ji)可(ke)采(cai)用(yong)(yong)(yong)雙(shuang)(shuang)滾筒(tong)傳(chuan)動(dong)(dong)，其(qi)特點是(shi)結(jie)構(gou)緊湊，還可(ke)增加圍(wei)包角以(yi)增加傳(chuan)動(dong)(dong)滾筒(tong)所能傳(chuan)遞的(de)牽(qian)引力(li)。使用(yong)(yong)(yong)雙(shuang)(shuang)滾筒(tong)傳(chuan)動(dong)(dong)時可(ke)以(yi)采(cai)用(yong)(yong)(yong)多(duo)電機(ji)(ji)分別傳(chuan)動(dong)(dong)，可(ke)以(yi)利用(yong)(yong)(yong)齒(chi)輪傳(chuan)動(dong)(dong)裝置使兩滾筒(tong)同速運轉。如雙(shuang)(shuang)滾筒(tong)傳(chuan)動(dong)(dong)仍不需要(yao)牽(qian)引力(li)需要(yao)，可(ke)采(cai)用(yong)(yong)(yong)多(duo)點驅(qu)動(dong)(dong)方式(shi)。
