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)(tong)(tong)(tong)是帶式輸送(song)機(ji)傳(chuan)動(dong)(dong)動(dong)(dong)力(li)(li)的主要部(bu)件。作為單(dan)(dan)點驅動(dong)(dong)方式來(lai)講(jiang)，可分成單(dan)(dan)滾筒(tong)(tong)(tong)(tong)傳(chuan)動(dong)(dong)及(ji)雙滾筒(tong)(tong)(tong)(tong)傳(chuan)動(dong)(dong)。單(dan)(dan)滾筒(tong)(tong)(tong)(tong)傳(chuan)動(dong)(dong)多(duo)用(yong)于功率(lv)不(bu)太大的輸送(song)機(ji)上(shang)，功率(lv)較大的輸送(song)機(ji)可采(cai)(cai)用(yong)雙滾筒(tong)(tong)(tong)(tong)傳(chuan)動(dong)(dong)，其(qi)特點是結構緊(jin)湊，還可增加圍包角以增加傳(chuan)動(dong)(dong)滾筒(tong)(tong)(tong)(tong)所能傳(chuan)遞的牽引力(li)(li)。使(shi)用(yong)雙滾筒(tong)(tong)(tong)(tong)傳(chuan)動(dong)(dong)時可以采(cai)(cai)用(yong)多(duo)電機(ji)分別傳(chuan)動(dong)(dong)，可以利用(yong)齒輪傳(chuan)動(dong)(dong)裝置使(shi)兩(liang)滾筒(tong)(tong)(tong)(tong)同速運轉。如雙滾筒(tong)(tong)(tong)(tong)傳(chuan)動(dong)(dong)仍不(bu)需要牽引力(li)(li)需要，可采(cai)(cai)用(yong)多(duo)點驅動(dong)(dong)方式。
