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。

傳動(dong)(dong)(dong)滾(gun)筒是(shi)帶式(shi)輸(shu)送(song)機(ji)(ji)傳動(dong)(dong)(dong)動(dong)(dong)(dong)力(li)的主(zhu)要部件(jian)。作(zuo)為(wei)單(dan)點驅(qu)動(dong)(dong)(dong)方(fang)式(shi)來講(jiang)，可(ke)分成單(dan)滾(gun)筒傳動(dong)(dong)(dong)及雙(shuang)滾(gun)筒傳動(dong)(dong)(dong)。單(dan)滾(gun)筒傳動(dong)(dong)(dong)多用(yong)于功(gong)率(lv)不太大的輸(shu)送(song)機(ji)(ji)上，功(gong)率(lv)較大的輸(shu)送(song)機(ji)(ji)可(ke)采用(yong)雙(shuang)滾(gun)筒傳動(dong)(dong)(dong)，其特點是(shi)結構緊湊，還可(ke)增(zeng)加(jia)圍包(bao)角以增(zeng)加(jia)傳動(dong)(dong)(dong)滾(gun)筒所能傳遞的牽(qian)引(yin)力(li)。使用(yong)雙(shuang)滾(gun)筒傳動(dong)(dong)(dong)時(shi)可(ke)以采用(yong)多電機(ji)(ji)分別(bie)傳動(dong)(dong)(dong)，可(ke)以利用(yong)齒輪(lun)傳動(dong)(dong)(dong)裝(zhuang)置使兩(liang)滾(gun)筒同速運(yun)轉。如雙(shuang)滾(gun)筒傳動(dong)(dong)(dong)仍(reng)不需要牽(qian)引(yin)力(li)需要，可(ke)采用(yong)多點驅(qu)動(dong)(dong)(dong)方(fang)式(shi)。
