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)滾(gun)(gun)筒(tong)(tong)是帶式(shi)(shi)輸(shu)(shu)送機(ji)傳(chuan)(chuan)動(dong)(dong)動(dong)(dong)力的主要部件。作為單點(dian)驅(qu)動(dong)(dong)方(fang)(fang)式(shi)(shi)來講，可分成單滾(gun)(gun)筒(tong)(tong)傳(chuan)(chuan)動(dong)(dong)及雙(shuang)滾(gun)(gun)筒(tong)(tong)傳(chuan)(chuan)動(dong)(dong)。單滾(gun)(gun)筒(tong)(tong)傳(chuan)(chuan)動(dong)(dong)多(duo)用(yong)于功率(lv)(lv)不太大的輸(shu)(shu)送機(ji)上(shang)，功率(lv)(lv)較大的輸(shu)(shu)送機(ji)可采(cai)用(yong)雙(shuang)滾(gun)(gun)筒(tong)(tong)傳(chuan)(chuan)動(dong)(dong)，其特點(dian)是結構(gou)緊湊，還可增(zeng)加圍包角以增(zeng)加傳(chuan)(chuan)動(dong)(dong)滾(gun)(gun)筒(tong)(tong)所能傳(chuan)(chuan)遞(di)的牽引力。使用(yong)雙(shuang)滾(gun)(gun)筒(tong)(tong)傳(chuan)(chuan)動(dong)(dong)時可以采(cai)用(yong)多(duo)電機(ji)分別傳(chuan)(chuan)動(dong)(dong)，可以利用(yong)齒輪傳(chuan)(chuan)動(dong)(dong)裝置使兩滾(gun)(gun)筒(tong)(tong)同速(su)運轉。如雙(shuang)滾(gun)(gun)筒(tong)(tong)傳(chuan)(chuan)動(dong)(dong)仍不需要牽引力需要，可采(cai)用(yong)多(duo)點(dian)驅(qu)動(dong)(dong)方(fang)(fang)式(shi)(shi)。
