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)(dong)(dong)(dong)滾(gun)(gun)筒(tong)(tong)是(shi)(shi)帶式輸送機(ji)(ji)(ji)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)動(dong)(dong)(dong)(dong)力的主要(yao)部件。作為單(dan)點驅動(dong)(dong)(dong)(dong)方式來(lai)講，可分成單(dan)滾(gun)(gun)筒(tong)(tong)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)及雙滾(gun)(gun)筒(tong)(tong)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)。單(dan)滾(gun)(gun)筒(tong)(tong)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)多(duo)(duo)用(yong)(yong)于功(gong)率不(bu)太大的輸送機(ji)(ji)(ji)上，功(gong)率較大的輸送機(ji)(ji)(ji)可采用(yong)(yong)雙滾(gun)(gun)筒(tong)(tong)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)，其特點是(shi)(shi)結構緊湊，還(huan)可增加圍(wei)包(bao)角以增加傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)滾(gun)(gun)筒(tong)(tong)所能傳(chuan)(chuan)(chuan)遞的牽引力。使用(yong)(yong)雙滾(gun)(gun)筒(tong)(tong)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)時(shi)可以采用(yong)(yong)多(duo)(duo)電機(ji)(ji)(ji)分別傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)，可以利用(yong)(yong)齒輪傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)裝(zhuang)置使兩滾(gun)(gun)筒(tong)(tong)同速運轉。如雙滾(gun)(gun)筒(tong)(tong)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)仍(reng)不(bu)需要(yao)牽引力需要(yao)，可采用(yong)(yong)多(duo)(duo)點驅動(dong)(dong)(dong)(dong)方式。
