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(gun)筒(tong)(tong)是帶(dai)式(shi)輸送(song)機傳(chuan)動(dong)(dong)(dong)(dong)動(dong)(dong)(dong)(dong)力(li)的主要部件。作為(wei)單(dan)(dan)點驅(qu)動(dong)(dong)(dong)(dong)方(fang)式(shi)來講(jiang)，可(ke)分成單(dan)(dan)滾(gun)筒(tong)(tong)傳(chuan)動(dong)(dong)(dong)(dong)及(ji)雙滾(gun)筒(tong)(tong)傳(chuan)動(dong)(dong)(dong)(dong)。單(dan)(dan)滾(gun)筒(tong)(tong)傳(chuan)動(dong)(dong)(dong)(dong)多用(yong)于功率不太大(da)的輸送(song)機上(shang)，功率較(jiao)大(da)的輸送(song)機可(ke)采用(yong)雙滾(gun)筒(tong)(tong)傳(chuan)動(dong)(dong)(dong)(dong)，其特(te)點是結構(gou)緊湊，還可(ke)增加圍包角以增加傳(chuan)動(dong)(dong)(dong)(dong)滾(gun)筒(tong)(tong)所能傳(chuan)遞的牽(qian)引(yin)力(li)。使(shi)用(yong)雙滾(gun)筒(tong)(tong)傳(chuan)動(dong)(dong)(dong)(dong)時可(ke)以采用(yong)多電機分別(bie)傳(chuan)動(dong)(dong)(dong)(dong)，可(ke)以利用(yong)齒輪(lun)傳(chuan)動(dong)(dong)(dong)(dong)裝置使(shi)兩滾(gun)筒(tong)(tong)同速運(yun)轉(zhuan)。如雙滾(gun)筒(tong)(tong)傳(chuan)動(dong)(dong)(dong)(dong)仍不需要牽(qian)引(yin)力(li)需要，可(ke)采用(yong)多點驅(qu)動(dong)(dong)(dong)(dong)方(fang)式(shi)。
