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。

傳動(dong)(dong)滾(gun)(gun)筒(tong)(tong)(tong)是帶(dai)式輸(shu)送(song)機傳動(dong)(dong)動(dong)(dong)力(li)的主要(yao)部(bu)件。作為單(dan)點驅動(dong)(dong)方式來講(jiang)，可分成(cheng)單(dan)滾(gun)(gun)筒(tong)(tong)(tong)傳動(dong)(dong)及(ji)雙滾(gun)(gun)筒(tong)(tong)(tong)傳動(dong)(dong)。單(dan)滾(gun)(gun)筒(tong)(tong)(tong)傳動(dong)(dong)多用于功率不(bu)太大(da)的輸(shu)送(song)機上(shang)，功率較大(da)的輸(shu)送(song)機可采(cai)(cai)用雙滾(gun)(gun)筒(tong)(tong)(tong)傳動(dong)(dong)，其特點是結(jie)構緊湊，還(huan)可增(zeng)加(jia)圍包角(jiao)以(yi)增(zeng)加(jia)傳動(dong)(dong)滾(gun)(gun)筒(tong)(tong)(tong)所能傳遞的牽(qian)引力(li)。使(shi)用雙滾(gun)(gun)筒(tong)(tong)(tong)傳動(dong)(dong)時可以(yi)采(cai)(cai)用多電機分別傳動(dong)(dong)，可以(yi)利(li)用齒輪傳動(dong)(dong)裝置使(shi)兩(liang)滾(gun)(gun)筒(tong)(tong)(tong)同速運轉。如(ru)雙滾(gun)(gun)筒(tong)(tong)(tong)傳動(dong)(dong)仍不(bu)需(xu)要(yao)牽(qian)引力(li)需(xu)要(yao)，可采(cai)(cai)用多點驅動(dong)(dong)方式。
