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)滾(gun)(gun)(gun)筒是(shi)帶式(shi)(shi)輸(shu)送機傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)動(dong)(dong)(dong)力的主要(yao)部件。作(zuo)為單點驅動(dong)(dong)(dong)方式(shi)(shi)來講(jiang)，可(ke)分成單滾(gun)(gun)(gun)筒傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)及雙(shuang)(shuang)滾(gun)(gun)(gun)筒傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)。單滾(gun)(gun)(gun)筒傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)多用于功率(lv)不太大的輸(shu)送機上，功率(lv)較大的輸(shu)送機可(ke)采用雙(shuang)(shuang)滾(gun)(gun)(gun)筒傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)，其特(te)點是(shi)結構緊湊，還可(ke)增(zeng)加圍包角以增(zeng)加傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)滾(gun)(gun)(gun)筒所(suo)能傳(chuan)(chuan)(chuan)遞的牽引力。使用雙(shuang)(shuang)滾(gun)(gun)(gun)筒傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)時可(ke)以采用多電(dian)機分別傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)，可(ke)以利用齒輪傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)裝置(zhi)使兩滾(gun)(gun)(gun)筒同速運轉。如雙(shuang)(shuang)滾(gun)(gun)(gun)筒傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)仍(reng)不需要(yao)牽引力需要(yao)，可(ke)采用多點驅動(dong)(dong)(dong)方式(shi)(shi)。
