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)滾(gun)筒(tong)(tong)是帶式(shi)(shi)輸(shu)送機(ji)(ji)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)動(dong)(dong)力(li)的(de)主要部件(jian)。作(zuo)為單點(dian)驅(qu)動(dong)(dong)方式(shi)(shi)來講，可(ke)(ke)分(fen)(fen)成單滾(gun)筒(tong)(tong)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)及雙滾(gun)筒(tong)(tong)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)。單滾(gun)筒(tong)(tong)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)多用于功(gong)率不(bu)太大的(de)輸(shu)送機(ji)(ji)上，功(gong)率較大的(de)輸(shu)送機(ji)(ji)可(ke)(ke)采用雙滾(gun)筒(tong)(tong)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)，其特點(dian)是結構緊湊(cou)，還可(ke)(ke)增加(jia)圍包角以增加(jia)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)滾(gun)筒(tong)(tong)所能傳(chuan)(chuan)(chuan)(chuan)遞的(de)牽(qian)引(yin)力(li)。使(shi)用雙滾(gun)筒(tong)(tong)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)時可(ke)(ke)以采用多電(dian)機(ji)(ji)分(fen)(fen)別傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)，可(ke)(ke)以利用齒輪傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)裝置(zhi)使(shi)兩滾(gun)筒(tong)(tong)同(tong)速(su)運轉。如雙滾(gun)筒(tong)(tong)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)仍不(bu)需要牽(qian)引(yin)力(li)需要，可(ke)(ke)采用多點(dian)驅(qu)動(dong)(dong)方式(shi)(shi)。
