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)是(shi)帶(dai)式輸送(song)機(ji)傳動(dong)(dong)動(dong)(dong)力(li)(li)的主要(yao)部(bu)件。作為(wei)單(dan)點驅動(dong)(dong)方式來講(jiang)，可(ke)分(fen)成單(dan)滾(gun)(gun)(gun)(gun)筒(tong)傳動(dong)(dong)及(ji)雙(shuang)滾(gun)(gun)(gun)(gun)筒(tong)傳動(dong)(dong)。單(dan)滾(gun)(gun)(gun)(gun)筒(tong)傳動(dong)(dong)多用(yong)(yong)于功(gong)率不太大的輸送(song)機(ji)上，功(gong)率較(jiao)大的輸送(song)機(ji)可(ke)采用(yong)(yong)雙(shuang)滾(gun)(gun)(gun)(gun)筒(tong)傳動(dong)(dong)，其特點是(shi)結構緊湊，還(huan)可(ke)增加圍包(bao)角以(yi)增加傳動(dong)(dong)滾(gun)(gun)(gun)(gun)筒(tong)所(suo)能傳遞的牽(qian)引力(li)(li)。使(shi)用(yong)(yong)雙(shuang)滾(gun)(gun)(gun)(gun)筒(tong)傳動(dong)(dong)時可(ke)以(yi)采用(yong)(yong)多電機(ji)分(fen)別(bie)傳動(dong)(dong)，可(ke)以(yi)利用(yong)(yong)齒輪傳動(dong)(dong)裝置使(shi)兩滾(gun)(gun)(gun)(gun)筒(tong)同速運轉。如雙(shuang)滾(gun)(gun)(gun)(gun)筒(tong)傳動(dong)(dong)仍不需(xu)要(yao)牽(qian)引力(li)(li)需(xu)要(yao)，可(ke)采用(yong)(yong)多點驅動(dong)(dong)方式。
