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)動(dong)(dong)(dong)滾筒(tong)(tong)是(shi)帶式輸(shu)送機(ji)傳(chuan)(chuan)動(dong)(dong)(dong)動(dong)(dong)(dong)力(li)的主要部件(jian)。作為單點(dian)驅動(dong)(dong)(dong)方式來講，可(ke)(ke)分成單滾筒(tong)(tong)傳(chuan)(chuan)動(dong)(dong)(dong)及(ji)雙滾筒(tong)(tong)傳(chuan)(chuan)動(dong)(dong)(dong)。單滾筒(tong)(tong)傳(chuan)(chuan)動(dong)(dong)(dong)多用(yong)于功率(lv)不太大(da)的輸(shu)送機(ji)上，功率(lv)較大(da)的輸(shu)送機(ji)可(ke)(ke)采(cai)用(yong)雙滾筒(tong)(tong)傳(chuan)(chuan)動(dong)(dong)(dong)，其特點(dian)是(shi)結構(gou)緊湊，還可(ke)(ke)增(zeng)加圍包角以(yi)增(zeng)加傳(chuan)(chuan)動(dong)(dong)(dong)滾筒(tong)(tong)所(suo)能傳(chuan)(chuan)遞的牽引力(li)。使用(yong)雙滾筒(tong)(tong)傳(chuan)(chuan)動(dong)(dong)(dong)時可(ke)(ke)以(yi)采(cai)用(yong)多電機(ji)分別傳(chuan)(chuan)動(dong)(dong)(dong)，可(ke)(ke)以(yi)利用(yong)齒輪傳(chuan)(chuan)動(dong)(dong)(dong)裝置使兩(liang)滾筒(tong)(tong)同速(su)運轉(zhuan)。如雙滾筒(tong)(tong)傳(chuan)(chuan)動(dong)(dong)(dong)仍不需要牽引力(li)需要，可(ke)(ke)采(cai)用(yong)多點(dian)驅動(dong)(dong)(dong)方式。
