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)筒(tong)是帶式輸送機(ji)傳(chuan)動(dong)(dong)動(dong)(dong)力(li)的主要(yao)部件。作為(wei)單點(dian)驅(qu)動(dong)(dong)方式來講，可(ke)(ke)(ke)分成單滾(gun)筒(tong)傳(chuan)動(dong)(dong)及雙滾(gun)筒(tong)傳(chuan)動(dong)(dong)。單滾(gun)筒(tong)傳(chuan)動(dong)(dong)多用于功率不太大的輸送機(ji)上，功率較大的輸送機(ji)可(ke)(ke)(ke)采用雙滾(gun)筒(tong)傳(chuan)動(dong)(dong)，其特點(dian)是結構緊(jin)湊，還可(ke)(ke)(ke)增(zeng)加圍包(bao)角以增(zeng)加傳(chuan)動(dong)(dong)滾(gun)筒(tong)所(suo)能傳(chuan)遞的牽引力(li)。使(shi)用雙滾(gun)筒(tong)傳(chuan)動(dong)(dong)時可(ke)(ke)(ke)以采用多電機(ji)分別傳(chuan)動(dong)(dong)，可(ke)(ke)(ke)以利用齒輪傳(chuan)動(dong)(dong)裝(zhuang)置使(shi)兩滾(gun)筒(tong)同速運轉。如雙滾(gun)筒(tong)傳(chuan)動(dong)(dong)仍不需(xu)要(yao)牽引力(li)需(xu)要(yao)，可(ke)(ke)(ke)采用多點(dian)驅(qu)動(dong)(dong)方式。
