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)動(dong)(dong)(dong)(dong)滾(gun)(gun)(gun)筒(tong)(tong)(tong)是帶式輸(shu)送(song)機(ji)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)動(dong)(dong)(dong)(dong)力(li)的(de)(de)主要(yao)部件。作為(wei)單(dan)(dan)點驅動(dong)(dong)(dong)(dong)方式來講(jiang)，可分(fen)(fen)成(cheng)單(dan)(dan)滾(gun)(gun)(gun)筒(tong)(tong)(tong)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)及雙(shuang)滾(gun)(gun)(gun)筒(tong)(tong)(tong)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)。單(dan)(dan)滾(gun)(gun)(gun)筒(tong)(tong)(tong)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)多用于功率不(bu)太大的(de)(de)輸(shu)送(song)機(ji)上(shang)，功率較大的(de)(de)輸(shu)送(song)機(ji)可采用雙(shuang)滾(gun)(gun)(gun)筒(tong)(tong)(tong)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)，其特點是結構緊(jin)湊，還可增加圍包角以增加傳(chuan)(chuan)動(dong)(dong)(dong)(dong)滾(gun)(gun)(gun)筒(tong)(tong)(tong)所能傳(chuan)(chuan)遞的(de)(de)牽引力(li)。使(shi)用雙(shuang)滾(gun)(gun)(gun)筒(tong)(tong)(tong)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)時可以采用多電機(ji)分(fen)(fen)別傳(chuan)(chuan)動(dong)(dong)(dong)(dong)，可以利用齒(chi)輪傳(chuan)(chuan)動(dong)(dong)(dong)(dong)裝置使(shi)兩滾(gun)(gun)(gun)筒(tong)(tong)(tong)同速運轉。如雙(shuang)滾(gun)(gun)(gun)筒(tong)(tong)(tong)傳(chuan)(chuan)動(dong)(dong)(dong)(dong)仍不(bu)需要(yao)牽引力(li)需要(yao)，可采用多點驅動(dong)(dong)(dong)(dong)方式。
