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)(dong)滾(gun)筒(tong)是(shi)帶(dai)式(shi)輸(shu)送機(ji)傳動(dong)(dong)(dong)(dong)動(dong)(dong)(dong)(dong)力的主要(yao)部件(jian)。作為單(dan)點驅動(dong)(dong)(dong)(dong)方(fang)式(shi)來講，可(ke)(ke)分成單(dan)滾(gun)筒(tong)傳動(dong)(dong)(dong)(dong)及雙滾(gun)筒(tong)傳動(dong)(dong)(dong)(dong)。單(dan)滾(gun)筒(tong)傳動(dong)(dong)(dong)(dong)多用(yong)于功率不太大的輸(shu)送機(ji)上，功率較大的輸(shu)送機(ji)可(ke)(ke)采用(yong)雙滾(gun)筒(tong)傳動(dong)(dong)(dong)(dong)，其特點是(shi)結構緊湊，還可(ke)(ke)增(zeng)加圍(wei)包角以增(zeng)加傳動(dong)(dong)(dong)(dong)滾(gun)筒(tong)所能傳遞的牽(qian)引力。使(shi)(shi)用(yong)雙滾(gun)筒(tong)傳動(dong)(dong)(dong)(dong)時可(ke)(ke)以采用(yong)多電機(ji)分別傳動(dong)(dong)(dong)(dong)，可(ke)(ke)以利用(yong)齒輪傳動(dong)(dong)(dong)(dong)裝置使(shi)(shi)兩滾(gun)筒(tong)同速(su)運轉。如雙滾(gun)筒(tong)傳動(dong)(dong)(dong)(dong)仍不需(xu)要(yao)牽(qian)引力需(xu)要(yao)，可(ke)(ke)采用(yong)多點驅動(dong)(dong)(dong)(dong)方(fang)式(shi)。
