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)(chuan)(chuan)動(dong)(dong)(dong)(dong)滾筒(tong)是帶(dai)式(shi)輸(shu)送(song)機(ji)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)動(dong)(dong)(dong)(dong)力(li)的(de)主(zhu)要(yao)部件。作為單點(dian)驅(qu)(qu)動(dong)(dong)(dong)(dong)方式(shi)來講(jiang)，可分成單滾筒(tong)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)及雙滾筒(tong)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)。單滾筒(tong)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)多用(yong)(yong)于(yu)功(gong)率(lv)(lv)不太(tai)大(da)的(de)輸(shu)送(song)機(ji)上，功(gong)率(lv)(lv)較大(da)的(de)輸(shu)送(song)機(ji)可采用(yong)(yong)雙滾筒(tong)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)，其特點(dian)是結構(gou)緊湊，還可增加圍包角以增加傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)滾筒(tong)所能傳(chuan)(chuan)(chuan)(chuan)遞的(de)牽引力(li)。使用(yong)(yong)雙滾筒(tong)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)時可以采用(yong)(yong)多電機(ji)分別傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)，可以利用(yong)(yong)齒輪傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)裝置使兩滾筒(tong)同速(su)運轉。如雙滾筒(tong)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)仍(reng)不需(xu)要(yao)牽引力(li)需(xu)要(yao)，可采用(yong)(yong)多點(dian)驅(qu)(qu)動(dong)(dong)(dong)(dong)方式(shi)。
