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)(dong)(dong)(dong)滾(gun)(gun)(gun)(gun)筒(tong)是帶(dai)式輸(shu)(shu)送機傳(chuan)(chuan)動(dong)(dong)(dong)(dong)動(dong)(dong)(dong)(dong)力(li)的(de)主(zhu)要部件(jian)。作(zuo)為(wei)單(dan)點驅(qu)動(dong)(dong)(dong)(dong)方(fang)式來講(jiang)，可(ke)分成單(dan)滾(gun)(gun)(gun)(gun)筒(tong)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)及雙(shuang)滾(gun)(gun)(gun)(gun)筒(tong)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)。單(dan)滾(gun)(gun)(gun)(gun)筒(tong)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)多(duo)用于功率不太大(da)的(de)輸(shu)(shu)送機上，功率較(jiao)大(da)的(de)輸(shu)(shu)送機可(ke)采(cai)用雙(shuang)滾(gun)(gun)(gun)(gun)筒(tong)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)，其特(te)點是結構(gou)緊湊，還可(ke)增(zeng)加圍包角以增(zeng)加傳(chuan)(chuan)動(dong)(dong)(dong)(dong)滾(gun)(gun)(gun)(gun)筒(tong)所能(neng)傳(chuan)(chuan)遞(di)的(de)牽引(yin)力(li)。使用雙(shuang)滾(gun)(gun)(gun)(gun)筒(tong)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)時可(ke)以采(cai)用多(duo)電(dian)機分別傳(chuan)(chuan)動(dong)(dong)(dong)(dong)，可(ke)以利用齒輪(lun)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)裝置使兩滾(gun)(gun)(gun)(gun)筒(tong)同速運轉。如雙(shuang)滾(gun)(gun)(gun)(gun)筒(tong)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)仍不需(xu)要牽引(yin)力(li)需(xu)要，可(ke)采(cai)用多(duo)點驅(qu)動(dong)(dong)(dong)(dong)方(fang)式。
