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)(gun)(gun)筒(tong)(tong)是(shi)帶式(shi)(shi)輸送機傳(chuan)動(dong)(dong)(dong)(dong)動(dong)(dong)(dong)(dong)力的(de)主要部(bu)件。作為單點(dian)驅(qu)動(dong)(dong)(dong)(dong)方式(shi)(shi)來講，可(ke)(ke)分成單滾(gun)(gun)(gun)筒(tong)(tong)傳(chuan)動(dong)(dong)(dong)(dong)及雙(shuang)滾(gun)(gun)(gun)筒(tong)(tong)傳(chuan)動(dong)(dong)(dong)(dong)。單滾(gun)(gun)(gun)筒(tong)(tong)傳(chuan)動(dong)(dong)(dong)(dong)多用(yong)于(yu)功率不(bu)太(tai)大(da)的(de)輸送機上，功率較大(da)的(de)輸送機可(ke)(ke)采用(yong)雙(shuang)滾(gun)(gun)(gun)筒(tong)(tong)傳(chuan)動(dong)(dong)(dong)(dong)，其特點(dian)是(shi)結構緊(jin)湊(cou)，還可(ke)(ke)增加圍(wei)包(bao)角(jiao)以增加傳(chuan)動(dong)(dong)(dong)(dong)滾(gun)(gun)(gun)筒(tong)(tong)所能傳(chuan)遞的(de)牽引(yin)力。使用(yong)雙(shuang)滾(gun)(gun)(gun)筒(tong)(tong)傳(chuan)動(dong)(dong)(dong)(dong)時可(ke)(ke)以采用(yong)多電機分別傳(chuan)動(dong)(dong)(dong)(dong)，可(ke)(ke)以利(li)用(yong)齒(chi)輪傳(chuan)動(dong)(dong)(dong)(dong)裝(zhuang)置使兩滾(gun)(gun)(gun)筒(tong)(tong)同(tong)速運轉(zhuan)。如雙(shuang)滾(gun)(gun)(gun)筒(tong)(tong)傳(chuan)動(dong)(dong)(dong)(dong)仍不(bu)需要牽引(yin)力需要，可(ke)(ke)采用(yong)多點(dian)驅(qu)動(dong)(dong)(dong)(dong)方式(shi)(shi)。
