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(gun)筒(tong)是(shi)帶式輸送(song)機傳(chuan)(chuan)動(dong)(dong)(dong)動(dong)(dong)(dong)力的(de)主要(yao)(yao)部件。作(zuo)為單點(dian)驅(qu)動(dong)(dong)(dong)方式來講，可(ke)(ke)(ke)分成單滾(gun)筒(tong)傳(chuan)(chuan)動(dong)(dong)(dong)及雙滾(gun)筒(tong)傳(chuan)(chuan)動(dong)(dong)(dong)。單滾(gun)筒(tong)傳(chuan)(chuan)動(dong)(dong)(dong)多(duo)(duo)用(yong)于功(gong)(gong)率(lv)不(bu)太大的(de)輸送(song)機上，功(gong)(gong)率(lv)較大的(de)輸送(song)機可(ke)(ke)(ke)采用(yong)雙滾(gun)筒(tong)傳(chuan)(chuan)動(dong)(dong)(dong)，其特點(dian)是(shi)結構緊湊，還可(ke)(ke)(ke)增加圍包(bao)角以增加傳(chuan)(chuan)動(dong)(dong)(dong)滾(gun)筒(tong)所(suo)能傳(chuan)(chuan)遞的(de)牽(qian)引(yin)力。使用(yong)雙滾(gun)筒(tong)傳(chuan)(chuan)動(dong)(dong)(dong)時(shi)可(ke)(ke)(ke)以采用(yong)多(duo)(duo)電機分別傳(chuan)(chuan)動(dong)(dong)(dong)，可(ke)(ke)(ke)以利用(yong)齒輪傳(chuan)(chuan)動(dong)(dong)(dong)裝置使兩滾(gun)筒(tong)同(tong)速(su)運轉。如雙滾(gun)筒(tong)傳(chuan)(chuan)動(dong)(dong)(dong)仍不(bu)需(xu)要(yao)(yao)牽(qian)引(yin)力需(xu)要(yao)(yao)，可(ke)(ke)(ke)采用(yong)多(duo)(duo)點(dian)驅(qu)動(dong)(dong)(dong)方式。
