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)(dong)滾(gun)筒(tong)(tong)(tong)是(shi)帶(dai)式輸送(song)機(ji)傳動(dong)(dong)(dong)動(dong)(dong)(dong)力(li)的(de)主要(yao)部件。作(zuo)為單點(dian)驅動(dong)(dong)(dong)方式來(lai)講，可(ke)(ke)(ke)分成單滾(gun)筒(tong)(tong)(tong)傳動(dong)(dong)(dong)及雙滾(gun)筒(tong)(tong)(tong)傳動(dong)(dong)(dong)。單滾(gun)筒(tong)(tong)(tong)傳動(dong)(dong)(dong)多用(yong)(yong)(yong)于功(gong)(gong)率不太大(da)的(de)輸送(song)機(ji)上，功(gong)(gong)率較(jiao)大(da)的(de)輸送(song)機(ji)可(ke)(ke)(ke)采用(yong)(yong)(yong)雙滾(gun)筒(tong)(tong)(tong)傳動(dong)(dong)(dong)，其特點(dian)是(shi)結(jie)構緊湊，還可(ke)(ke)(ke)增(zeng)加(jia)圍包角以(yi)增(zeng)加(jia)傳動(dong)(dong)(dong)滾(gun)筒(tong)(tong)(tong)所能(neng)傳遞的(de)牽(qian)引力(li)。使用(yong)(yong)(yong)雙滾(gun)筒(tong)(tong)(tong)傳動(dong)(dong)(dong)時可(ke)(ke)(ke)以(yi)采用(yong)(yong)(yong)多電機(ji)分別傳動(dong)(dong)(dong)，可(ke)(ke)(ke)以(yi)利(li)用(yong)(yong)(yong)齒輪傳動(dong)(dong)(dong)裝置使兩滾(gun)筒(tong)(tong)(tong)同速運轉。如(ru)雙滾(gun)筒(tong)(tong)(tong)傳動(dong)(dong)(dong)仍不需要(yao)牽(qian)引力(li)需要(yao)，可(ke)(ke)(ke)采用(yong)(yong)(yong)多點(dian)驅動(dong)(dong)(dong)方式。
