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)動(dong)(dong)(dong)滾(gun)(gun)筒(tong)是帶式輸(shu)送機(ji)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)動(dong)(dong)(dong)力的主要部件。作(zuo)為單點(dian)驅動(dong)(dong)(dong)方式來講(jiang)，可分成(cheng)單滾(gun)(gun)筒(tong)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)及雙滾(gun)(gun)筒(tong)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)。單滾(gun)(gun)筒(tong)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)多(duo)用(yong)于(yu)功(gong)率不(bu)太大的輸(shu)送機(ji)上，功(gong)率較大的輸(shu)送機(ji)可采(cai)用(yong)雙滾(gun)(gun)筒(tong)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)，其特點(dian)是結(jie)構緊湊，還可增加圍包角以增加傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)滾(gun)(gun)筒(tong)所能傳(chuan)(chuan)(chuan)遞(di)的牽引力。使(shi)用(yong)雙滾(gun)(gun)筒(tong)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)時可以采(cai)用(yong)多(duo)電機(ji)分別(bie)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)，可以利用(yong)齒輪傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)裝(zhuang)置使(shi)兩(liang)滾(gun)(gun)筒(tong)同速運轉。如雙滾(gun)(gun)筒(tong)傳(chuan)(chuan)(chuan)動(dong)(dong)(dong)仍不(bu)需要牽引力需要，可采(cai)用(yong)多(duo)點(dian)驅動(dong)(dong)(dong)方式。
