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)滾(gun)(gun)(gun)(gun)筒(tong)(tong)是(shi)帶式輸(shu)送機(ji)傳(chuan)(chuan)動(dong)動(dong)力的(de)主要(yao)部件。作(zuo)為單點驅動(dong)方(fang)式來(lai)講，可(ke)分成單滾(gun)(gun)(gun)(gun)筒(tong)(tong)傳(chuan)(chuan)動(dong)及(ji)雙滾(gun)(gun)(gun)(gun)筒(tong)(tong)傳(chuan)(chuan)動(dong)。單滾(gun)(gun)(gun)(gun)筒(tong)(tong)傳(chuan)(chuan)動(dong)多用(yong)(yong)于(yu)功率(lv)不(bu)太大的(de)輸(shu)送機(ji)上(shang)，功率(lv)較(jiao)大的(de)輸(shu)送機(ji)可(ke)采用(yong)(yong)雙滾(gun)(gun)(gun)(gun)筒(tong)(tong)傳(chuan)(chuan)動(dong)，其特點是(shi)結構緊湊，還可(ke)增加(jia)圍包角以增加(jia)傳(chuan)(chuan)動(dong)滾(gun)(gun)(gun)(gun)筒(tong)(tong)所(suo)能(neng)傳(chuan)(chuan)遞的(de)牽引力。使(shi)用(yong)(yong)雙滾(gun)(gun)(gun)(gun)筒(tong)(tong)傳(chuan)(chuan)動(dong)時可(ke)以采用(yong)(yong)多電機(ji)分別(bie)傳(chuan)(chuan)動(dong)，可(ke)以利用(yong)(yong)齒輪傳(chuan)(chuan)動(dong)裝(zhuang)置使(shi)兩(liang)滾(gun)(gun)(gun)(gun)筒(tong)(tong)同(tong)速運轉。如雙滾(gun)(gun)(gun)(gun)筒(tong)(tong)傳(chuan)(chuan)動(dong)仍不(bu)需(xu)要(yao)牽引力需(xu)要(yao)，可(ke)采用(yong)(yong)多點驅動(dong)方(fang)式。
