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)(chuan)動(dong)滾(gun)筒(tong)(tong)是帶式輸(shu)送(song)(song)機(ji)傳(chuan)(chuan)(chuan)動(dong)動(dong)力(li)的(de)主要(yao)部件。作(zuo)為單點驅動(dong)方(fang)式來講，可(ke)分(fen)成單滾(gun)筒(tong)(tong)傳(chuan)(chuan)(chuan)動(dong)及雙滾(gun)筒(tong)(tong)傳(chuan)(chuan)(chuan)動(dong)。單滾(gun)筒(tong)(tong)傳(chuan)(chuan)(chuan)動(dong)多(duo)用(yong)于功率不(bu)太大的(de)輸(shu)送(song)(song)機(ji)上，功率較大的(de)輸(shu)送(song)(song)機(ji)可(ke)采(cai)用(yong)雙滾(gun)筒(tong)(tong)傳(chuan)(chuan)(chuan)動(dong)，其特點是結(jie)構緊湊，還(huan)可(ke)增(zeng)加圍(wei)包角以增(zeng)加傳(chuan)(chuan)(chuan)動(dong)滾(gun)筒(tong)(tong)所能傳(chuan)(chuan)(chuan)遞(di)的(de)牽引力(li)。使用(yong)雙滾(gun)筒(tong)(tong)傳(chuan)(chuan)(chuan)動(dong)時(shi)可(ke)以采(cai)用(yong)多(duo)電(dian)機(ji)分(fen)別(bie)傳(chuan)(chuan)(chuan)動(dong)，可(ke)以利用(yong)齒(chi)輪傳(chuan)(chuan)(chuan)動(dong)裝置使兩滾(gun)筒(tong)(tong)同速運(yun)轉。如(ru)雙滾(gun)筒(tong)(tong)傳(chuan)(chuan)(chuan)動(dong)仍(reng)不(bu)需要(yao)牽引力(li)需要(yao)，可(ke)采(cai)用(yong)多(duo)點驅動(dong)方(fang)式。
