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)滾(gun)筒是帶式(shi)輸(shu)(shu)送(song)機(ji)傳(chuan)(chuan)(chuan)動(dong)(dong)動(dong)(dong)力的主要部件。作(zuo)為單(dan)(dan)點(dian)(dian)(dian)驅(qu)動(dong)(dong)方式(shi)來(lai)講，可(ke)(ke)分(fen)成(cheng)單(dan)(dan)滾(gun)筒傳(chuan)(chuan)(chuan)動(dong)(dong)及雙(shuang)(shuang)滾(gun)筒傳(chuan)(chuan)(chuan)動(dong)(dong)。單(dan)(dan)滾(gun)筒傳(chuan)(chuan)(chuan)動(dong)(dong)多用(yong)于(yu)功率(lv)(lv)不太大(da)的輸(shu)(shu)送(song)機(ji)上(shang)，功率(lv)(lv)較大(da)的輸(shu)(shu)送(song)機(ji)可(ke)(ke)采用(yong)雙(shuang)(shuang)滾(gun)筒傳(chuan)(chuan)(chuan)動(dong)(dong)，其特點(dian)(dian)(dian)是結(jie)構緊(jin)湊，還(huan)可(ke)(ke)增(zeng)加圍包角以(yi)(yi)增(zeng)加傳(chuan)(chuan)(chuan)動(dong)(dong)滾(gun)筒所能傳(chuan)(chuan)(chuan)遞的牽引力。使用(yong)雙(shuang)(shuang)滾(gun)筒傳(chuan)(chuan)(chuan)動(dong)(dong)時(shi)可(ke)(ke)以(yi)(yi)采用(yong)多電機(ji)分(fen)別傳(chuan)(chuan)(chuan)動(dong)(dong)，可(ke)(ke)以(yi)(yi)利用(yong)齒輪傳(chuan)(chuan)(chuan)動(dong)(dong)裝置使兩滾(gun)筒同速運(yun)轉。如雙(shuang)(shuang)滾(gun)筒傳(chuan)(chuan)(chuan)動(dong)(dong)仍不需要牽引力需要，可(ke)(ke)采用(yong)多點(dian)(dian)(dian)驅(qu)動(dong)(dong)方式(shi)。
