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。

傳動(dong)(dong)滾(gun)(gun)(gun)(gun)筒(tong)(tong)是帶式(shi)輸送(song)(song)機(ji)傳動(dong)(dong)動(dong)(dong)力的主(zhu)要部件。作(zuo)為(wei)單(dan)點驅動(dong)(dong)方式(shi)來講，可(ke)分(fen)成單(dan)滾(gun)(gun)(gun)(gun)筒(tong)(tong)傳動(dong)(dong)及雙滾(gun)(gun)(gun)(gun)筒(tong)(tong)傳動(dong)(dong)。單(dan)滾(gun)(gun)(gun)(gun)筒(tong)(tong)傳動(dong)(dong)多(duo)用(yong)(yong)于功率(lv)不太大的輸送(song)(song)機(ji)上，功率(lv)較大的輸送(song)(song)機(ji)可(ke)采(cai)用(yong)(yong)雙滾(gun)(gun)(gun)(gun)筒(tong)(tong)傳動(dong)(dong)，其特(te)點是結構緊湊，還(huan)可(ke)增(zeng)加圍包(bao)角以(yi)增(zeng)加傳動(dong)(dong)滾(gun)(gun)(gun)(gun)筒(tong)(tong)所能傳遞的牽引力。使用(yong)(yong)雙滾(gun)(gun)(gun)(gun)筒(tong)(tong)傳動(dong)(dong)時可(ke)以(yi)采(cai)用(yong)(yong)多(duo)電機(ji)分(fen)別傳動(dong)(dong)，可(ke)以(yi)利用(yong)(yong)齒輪傳動(dong)(dong)裝置使兩滾(gun)(gun)(gun)(gun)筒(tong)(tong)同速運轉。如雙滾(gun)(gun)(gun)(gun)筒(tong)(tong)傳動(dong)(dong)仍不需要牽引力需要，可(ke)采(cai)用(yong)(yong)多(duo)點驅動(dong)(dong)方式(shi)。
