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)動(dong)(dong)(dong)(dong)(dong)滾(gun)(gun)(gun)筒(tong)是帶式輸(shu)送(song)機(ji)傳(chuan)動(dong)(dong)(dong)(dong)(dong)動(dong)(dong)(dong)(dong)(dong)力的(de)(de)主(zhu)要部件(jian)。作為單(dan)點驅動(dong)(dong)(dong)(dong)(dong)方(fang)式來(lai)講，可(ke)分成單(dan)滾(gun)(gun)(gun)筒(tong)傳(chuan)動(dong)(dong)(dong)(dong)(dong)及雙滾(gun)(gun)(gun)筒(tong)傳(chuan)動(dong)(dong)(dong)(dong)(dong)。單(dan)滾(gun)(gun)(gun)筒(tong)傳(chuan)動(dong)(dong)(dong)(dong)(dong)多(duo)用(yong)于功(gong)率不(bu)太大的(de)(de)輸(shu)送(song)機(ji)上，功(gong)率較大的(de)(de)輸(shu)送(song)機(ji)可(ke)采用(yong)雙滾(gun)(gun)(gun)筒(tong)傳(chuan)動(dong)(dong)(dong)(dong)(dong)，其特(te)點是結構緊湊，還(huan)可(ke)增(zeng)加圍包角(jiao)以增(zeng)加傳(chuan)動(dong)(dong)(dong)(dong)(dong)滾(gun)(gun)(gun)筒(tong)所能傳(chuan)遞的(de)(de)牽引力。使用(yong)雙滾(gun)(gun)(gun)筒(tong)傳(chuan)動(dong)(dong)(dong)(dong)(dong)時可(ke)以采用(yong)多(duo)電機(ji)分別傳(chuan)動(dong)(dong)(dong)(dong)(dong)，可(ke)以利用(yong)齒輪(lun)傳(chuan)動(dong)(dong)(dong)(dong)(dong)裝置使兩滾(gun)(gun)(gun)筒(tong)同速運(yun)轉。如雙滾(gun)(gun)(gun)筒(tong)傳(chuan)動(dong)(dong)(dong)(dong)(dong)仍不(bu)需要牽引力需要，可(ke)采用(yong)多(duo)點驅動(dong)(dong)(dong)(dong)(dong)方(fang)式。
