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)滾(gun)筒(tong)是帶式輸(shu)送機傳(chuan)(chuan)動(dong)(dong)動(dong)(dong)力(li)(li)的主要部件。作為單(dan)點驅動(dong)(dong)方式來講，可(ke)(ke)(ke)分成(cheng)單(dan)滾(gun)筒(tong)傳(chuan)(chuan)動(dong)(dong)及雙(shuang)滾(gun)筒(tong)傳(chuan)(chuan)動(dong)(dong)。單(dan)滾(gun)筒(tong)傳(chuan)(chuan)動(dong)(dong)多用(yong)于功率不太大的輸(shu)送機上(shang)，功率較大的輸(shu)送機可(ke)(ke)(ke)采(cai)用(yong)雙(shuang)滾(gun)筒(tong)傳(chuan)(chuan)動(dong)(dong)，其特點是結(jie)構緊湊，還可(ke)(ke)(ke)增(zeng)(zeng)加圍包角以(yi)增(zeng)(zeng)加傳(chuan)(chuan)動(dong)(dong)滾(gun)筒(tong)所(suo)能(neng)傳(chuan)(chuan)遞的牽引力(li)(li)。使用(yong)雙(shuang)滾(gun)筒(tong)傳(chuan)(chuan)動(dong)(dong)時可(ke)(ke)(ke)以(yi)采(cai)用(yong)多電機分別傳(chuan)(chuan)動(dong)(dong)，可(ke)(ke)(ke)以(yi)利用(yong)齒(chi)輪傳(chuan)(chuan)動(dong)(dong)裝置使兩滾(gun)筒(tong)同速(su)運轉。如(ru)雙(shuang)滾(gun)筒(tong)傳(chuan)(chuan)動(dong)(dong)仍不需要牽引力(li)(li)需要，可(ke)(ke)(ke)采(cai)用(yong)多點驅動(dong)(dong)方式。
