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)(gun)(gun)筒(tong)(tong)(tong)(tong)是(shi)帶(dai)式輸(shu)(shu)送機(ji)傳(chuan)動(dong)動(dong)力(li)(li)的(de)(de)(de)主要(yao)部(bu)件。作為單(dan)點驅(qu)動(dong)方式來(lai)講(jiang)，可分成(cheng)單(dan)滾(gun)(gun)(gun)(gun)筒(tong)(tong)(tong)(tong)傳(chuan)動(dong)及雙(shuang)(shuang)滾(gun)(gun)(gun)(gun)筒(tong)(tong)(tong)(tong)傳(chuan)動(dong)。單(dan)滾(gun)(gun)(gun)(gun)筒(tong)(tong)(tong)(tong)傳(chuan)動(dong)多(duo)(duo)用于功率不(bu)太大的(de)(de)(de)輸(shu)(shu)送機(ji)上，功率較大的(de)(de)(de)輸(shu)(shu)送機(ji)可采(cai)用雙(shuang)(shuang)滾(gun)(gun)(gun)(gun)筒(tong)(tong)(tong)(tong)傳(chuan)動(dong)，其(qi)特點是(shi)結構緊湊，還可增加圍包角(jiao)以增加傳(chuan)動(dong)滾(gun)(gun)(gun)(gun)筒(tong)(tong)(tong)(tong)所能傳(chuan)遞的(de)(de)(de)牽(qian)引力(li)(li)。使用雙(shuang)(shuang)滾(gun)(gun)(gun)(gun)筒(tong)(tong)(tong)(tong)傳(chuan)動(dong)時可以采(cai)用多(duo)(duo)電(dian)機(ji)分別(bie)傳(chuan)動(dong)，可以利用齒輪傳(chuan)動(dong)裝置使兩滾(gun)(gun)(gun)(gun)筒(tong)(tong)(tong)(tong)同速運轉。如雙(shuang)(shuang)滾(gun)(gun)(gun)(gun)筒(tong)(tong)(tong)(tong)傳(chuan)動(dong)仍不(bu)需要(yao)牽(qian)引力(li)(li)需要(yao)，可采(cai)用多(duo)(duo)點驅(qu)動(dong)方式。
