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)動(dong)(dong)滾(gun)(gun)筒(tong)是帶式輸(shu)送機(ji)(ji)傳(chuan)動(dong)(dong)動(dong)(dong)力的主要(yao)部件。作為單(dan)(dan)點驅(qu)動(dong)(dong)方式來講，可(ke)(ke)(ke)(ke)分成單(dan)(dan)滾(gun)(gun)筒(tong)傳(chuan)動(dong)(dong)及(ji)雙滾(gun)(gun)筒(tong)傳(chuan)動(dong)(dong)。單(dan)(dan)滾(gun)(gun)筒(tong)傳(chuan)動(dong)(dong)多用(yong)(yong)(yong)于功率不太大的輸(shu)送機(ji)(ji)上，功率較大的輸(shu)送機(ji)(ji)可(ke)(ke)(ke)(ke)采用(yong)(yong)(yong)雙滾(gun)(gun)筒(tong)傳(chuan)動(dong)(dong)，其特點是結構緊湊(cou)，還(huan)可(ke)(ke)(ke)(ke)增(zeng)加(jia)圍包角(jiao)以(yi)增(zeng)加(jia)傳(chuan)動(dong)(dong)滾(gun)(gun)筒(tong)所能傳(chuan)遞的牽(qian)引力。使(shi)用(yong)(yong)(yong)雙滾(gun)(gun)筒(tong)傳(chuan)動(dong)(dong)時可(ke)(ke)(ke)(ke)以(yi)采用(yong)(yong)(yong)多電機(ji)(ji)分別傳(chuan)動(dong)(dong)，可(ke)(ke)(ke)(ke)以(yi)利用(yong)(yong)(yong)齒輪傳(chuan)動(dong)(dong)裝置使(shi)兩滾(gun)(gun)筒(tong)同(tong)速(su)運轉(zhuan)。如雙滾(gun)(gun)筒(tong)傳(chuan)動(dong)(dong)仍(reng)不需要(yao)牽(qian)引力需要(yao)，可(ke)(ke)(ke)(ke)采用(yong)(yong)(yong)多點驅(qu)動(dong)(dong)方式。
