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)(dong)(dong)滾筒(tong)(tong)是帶式輸送機傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)動(dong)(dong)(dong)(dong)(dong)(dong)力的(de)主要部件。作為單(dan)點(dian)(dian)驅動(dong)(dong)(dong)(dong)(dong)(dong)方式來講，可(ke)分(fen)成單(dan)滾筒(tong)(tong)傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)及雙滾筒(tong)(tong)傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)。單(dan)滾筒(tong)(tong)傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)多(duo)用于功率不太大的(de)輸送機上，功率較大的(de)輸送機可(ke)采用雙滾筒(tong)(tong)傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)，其特點(dian)(dian)是結構(gou)緊湊，還可(ke)增加圍包角以增加傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)滾筒(tong)(tong)所(suo)能傳(chuan)遞(di)的(de)牽引(yin)力。使用雙滾筒(tong)(tong)傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)時可(ke)以采用多(duo)電機分(fen)別傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)，可(ke)以利用齒(chi)輪傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)裝(zhuang)置(zhi)使兩(liang)滾筒(tong)(tong)同速運轉。如(ru)雙滾筒(tong)(tong)傳(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)仍不需(xu)要牽引(yin)力需(xu)要，可(ke)采用多(duo)點(dian)(dian)驅動(dong)(dong)(dong)(dong)(dong)(dong)方式。
