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)(gun)筒是帶式(shi)(shi)輸(shu)送機傳(chuan)(chuan)動(dong)(dong)(dong)動(dong)(dong)(dong)力(li)的(de)(de)(de)主要部件。作為單點(dian)驅動(dong)(dong)(dong)方式(shi)(shi)來講，可(ke)(ke)分(fen)成單滾(gun)(gun)筒傳(chuan)(chuan)動(dong)(dong)(dong)及雙(shuang)(shuang)(shuang)滾(gun)(gun)筒傳(chuan)(chuan)動(dong)(dong)(dong)。單滾(gun)(gun)筒傳(chuan)(chuan)動(dong)(dong)(dong)多用(yong)(yong)(yong)于(yu)功率不(bu)太大的(de)(de)(de)輸(shu)送機上，功率較大的(de)(de)(de)輸(shu)送機可(ke)(ke)采用(yong)(yong)(yong)雙(shuang)(shuang)(shuang)滾(gun)(gun)筒傳(chuan)(chuan)動(dong)(dong)(dong)，其特點(dian)是結構緊湊，還(huan)可(ke)(ke)增加圍包角以增加傳(chuan)(chuan)動(dong)(dong)(dong)滾(gun)(gun)筒所能傳(chuan)(chuan)遞的(de)(de)(de)牽引力(li)。使(shi)用(yong)(yong)(yong)雙(shuang)(shuang)(shuang)滾(gun)(gun)筒傳(chuan)(chuan)動(dong)(dong)(dong)時可(ke)(ke)以采用(yong)(yong)(yong)多電機分(fen)別傳(chuan)(chuan)動(dong)(dong)(dong)，可(ke)(ke)以利用(yong)(yong)(yong)齒輪傳(chuan)(chuan)動(dong)(dong)(dong)裝置使(shi)兩滾(gun)(gun)筒同速運(yun)轉。如(ru)雙(shuang)(shuang)(shuang)滾(gun)(gun)筒傳(chuan)(chuan)動(dong)(dong)(dong)仍不(bu)需要牽引力(li)需要，可(ke)(ke)采用(yong)(yong)(yong)多點(dian)驅動(dong)(dong)(dong)方式(shi)(shi)。
