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)滾(gun)(gun)筒是帶(dai)式(shi)輸送機傳(chuan)動(dong)(dong)(dong)動(dong)(dong)(dong)力(li)的主要(yao)部件(jian)。作(zuo)為單(dan)點(dian)驅(qu)動(dong)(dong)(dong)方(fang)式(shi)來講，可(ke)分(fen)成單(dan)滾(gun)(gun)筒傳(chuan)動(dong)(dong)(dong)及雙滾(gun)(gun)筒傳(chuan)動(dong)(dong)(dong)。單(dan)滾(gun)(gun)筒傳(chuan)動(dong)(dong)(dong)多用(yong)(yong)(yong)于(yu)功率(lv)(lv)不太(tai)大的輸送機上，功率(lv)(lv)較大的輸送機可(ke)采用(yong)(yong)(yong)雙滾(gun)(gun)筒傳(chuan)動(dong)(dong)(dong)，其特(te)點(dian)是結構緊湊，還可(ke)增(zeng)加(jia)圍包角以(yi)增(zeng)加(jia)傳(chuan)動(dong)(dong)(dong)滾(gun)(gun)筒所能(neng)傳(chuan)遞的牽(qian)引力(li)。使用(yong)(yong)(yong)雙滾(gun)(gun)筒傳(chuan)動(dong)(dong)(dong)時可(ke)以(yi)采用(yong)(yong)(yong)多電機分(fen)別傳(chuan)動(dong)(dong)(dong)，可(ke)以(yi)利用(yong)(yong)(yong)齒(chi)輪傳(chuan)動(dong)(dong)(dong)裝(zhuang)置使兩滾(gun)(gun)筒同速運轉。如(ru)雙滾(gun)(gun)筒傳(chuan)動(dong)(dong)(dong)仍不需(xu)(xu)要(yao)牽(qian)引力(li)需(xu)(xu)要(yao)，可(ke)采用(yong)(yong)(yong)多點(dian)驅(qu)動(dong)(dong)(dong)方(fang)式(shi)。
