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(shi)輸(shu)送機(ji)傳(chuan)(chuan)(chuan)動(dong)動(dong)力(li)的主要部件(jian)。作(zuo)為(wei)單點驅(qu)動(dong)方(fang)式(shi)來講(jiang)，可(ke)(ke)分成單滾(gun)筒(tong)(tong)傳(chuan)(chuan)(chuan)動(dong)及(ji)雙(shuang)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(gong)率不太(tai)大的輸(shu)送機(ji)上，功(gong)率較大的輸(shu)送機(ji)可(ke)(ke)采用(yong)雙(shuang)滾(gun)筒(tong)(tong)傳(chuan)(chuan)(chuan)動(dong)，其(qi)特點是結構緊湊，還可(ke)(ke)增(zeng)加圍包(bao)角以(yi)增(zeng)加傳(chuan)(chuan)(chuan)動(dong)滾(gun)筒(tong)(tong)所能傳(chuan)(chuan)(chuan)遞的牽引力(li)。使(shi)用(yong)雙(shuang)滾(gun)筒(tong)(tong)傳(chuan)(chuan)(chuan)動(dong)時可(ke)(ke)以(yi)采用(yong)多(duo)電機(ji)分別傳(chuan)(chuan)(chuan)動(dong)，可(ke)(ke)以(yi)利用(yong)齒輪傳(chuan)(chuan)(chuan)動(dong)裝置使(shi)兩滾(gun)筒(tong)(tong)同速運轉。如雙(shuang)滾(gun)筒(tong)(tong)傳(chuan)(chuan)(chuan)動(dong)仍不需要牽引力(li)需要，可(ke)(ke)采用(yong)多(duo)點驅(qu)動(dong)方(fang)式(shi)。
