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)是帶式輸(shu)(shu)送(song)機(ji)傳(chuan)(chuan)(chuan)動(dong)動(dong)力(li)的(de)主(zhu)要部件(jian)。作(zuo)為單點驅動(dong)方式來講，可(ke)(ke)(ke)分成單滾(gun)筒(tong)傳(chuan)(chuan)(chuan)動(dong)及(ji)雙滾(gun)筒(tong)傳(chuan)(chuan)(chuan)動(dong)。單滾(gun)筒(tong)傳(chuan)(chuan)(chuan)動(dong)多(duo)用(yong)(yong)于功(gong)率不太(tai)大的(de)輸(shu)(shu)送(song)機(ji)上，功(gong)率較大的(de)輸(shu)(shu)送(song)機(ji)可(ke)(ke)(ke)采(cai)(cai)用(yong)(yong)雙滾(gun)筒(tong)傳(chuan)(chuan)(chuan)動(dong)，其特點是結構(gou)緊湊，還(huan)可(ke)(ke)(ke)增(zeng)加圍包角以(yi)(yi)增(zeng)加傳(chuan)(chuan)(chuan)動(dong)滾(gun)筒(tong)所能(neng)傳(chuan)(chuan)(chuan)遞的(de)牽引力(li)。使用(yong)(yong)雙滾(gun)筒(tong)傳(chuan)(chuan)(chuan)動(dong)時可(ke)(ke)(ke)以(yi)(yi)采(cai)(cai)用(yong)(yong)多(duo)電機(ji)分別(bie)傳(chuan)(chuan)(chuan)動(dong)，可(ke)(ke)(ke)以(yi)(yi)利(li)用(yong)(yong)齒輪傳(chuan)(chuan)(chuan)動(dong)裝(zhuang)置使兩滾(gun)筒(tong)同速運轉。如雙滾(gun)筒(tong)傳(chuan)(chuan)(chuan)動(dong)仍(reng)不需(xu)(xu)要牽引力(li)需(xu)(xu)要，可(ke)(ke)(ke)采(cai)(cai)用(yong)(yong)多(duo)點驅動(dong)方式。
