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)滾筒(tong)是帶式輸送(song)機(ji)傳(chuan)動(dong)(dong)(dong)(dong)動(dong)(dong)(dong)(dong)力的(de)主要(yao)部件。作為單(dan)點驅動(dong)(dong)(dong)(dong)方式來講，可分成(cheng)單(dan)滾筒(tong)傳(chuan)動(dong)(dong)(dong)(dong)及(ji)雙滾筒(tong)傳(chuan)動(dong)(dong)(dong)(dong)。單(dan)滾筒(tong)傳(chuan)動(dong)(dong)(dong)(dong)多(duo)用于(yu)功率(lv)不太大(da)的(de)輸送(song)機(ji)上，功率(lv)較大(da)的(de)輸送(song)機(ji)可采(cai)用雙滾筒(tong)傳(chuan)動(dong)(dong)(dong)(dong)，其特點是結構緊湊，還可增(zeng)加圍包角以(yi)增(zeng)加傳(chuan)動(dong)(dong)(dong)(dong)滾筒(tong)所能傳(chuan)遞(di)的(de)牽引力。使用雙滾筒(tong)傳(chuan)動(dong)(dong)(dong)(dong)時(shi)可以(yi)采(cai)用多(duo)電機(ji)分別(bie)傳(chuan)動(dong)(dong)(dong)(dong)，可以(yi)利用齒輪傳(chuan)動(dong)(dong)(dong)(dong)裝置(zhi)使兩滾筒(tong)同速運轉。如雙滾筒(tong)傳(chuan)動(dong)(dong)(dong)(dong)仍(reng)不需要(yao)牽引力需要(yao)，可采(cai)用多(duo)點驅動(dong)(dong)(dong)(dong)方式。
