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)滾(gun)(gun)筒(tong)(tong)是帶式(shi)輸(shu)送(song)機傳(chuan)動(dong)(dong)(dong)(dong)動(dong)(dong)(dong)(dong)力(li)的(de)主要(yao)(yao)(yao)部件。作為單點(dian)驅動(dong)(dong)(dong)(dong)方(fang)式(shi)來講，可分(fen)成單滾(gun)(gun)筒(tong)(tong)傳(chuan)動(dong)(dong)(dong)(dong)及雙滾(gun)(gun)筒(tong)(tong)傳(chuan)動(dong)(dong)(dong)(dong)。單滾(gun)(gun)筒(tong)(tong)傳(chuan)動(dong)(dong)(dong)(dong)多(duo)用(yong)于功率不太大(da)(da)的(de)輸(shu)送(song)機上，功率較(jiao)大(da)(da)的(de)輸(shu)送(song)機可采(cai)用(yong)雙滾(gun)(gun)筒(tong)(tong)傳(chuan)動(dong)(dong)(dong)(dong)，其特(te)點(dian)是結構緊湊，還(huan)可增(zeng)加(jia)圍包角以增(zeng)加(jia)傳(chuan)動(dong)(dong)(dong)(dong)滾(gun)(gun)筒(tong)(tong)所能傳(chuan)遞的(de)牽(qian)引力(li)。使用(yong)雙滾(gun)(gun)筒(tong)(tong)傳(chuan)動(dong)(dong)(dong)(dong)時可以采(cai)用(yong)多(duo)電機分(fen)別傳(chuan)動(dong)(dong)(dong)(dong)，可以利用(yong)齒輪傳(chuan)動(dong)(dong)(dong)(dong)裝置使兩滾(gun)(gun)筒(tong)(tong)同速運轉。如雙滾(gun)(gun)筒(tong)(tong)傳(chuan)動(dong)(dong)(dong)(dong)仍不需要(yao)(yao)(yao)牽(qian)引力(li)需要(yao)(yao)(yao)，可采(cai)用(yong)多(duo)點(dian)驅動(dong)(dong)(dong)(dong)方(fang)式(shi)。
