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)(chuan)動(dong)(dong)滾(gun)(gun)(gun)筒(tong)(tong)(tong)是(shi)帶式輸送機(ji)(ji)傳(chuan)(chuan)動(dong)(dong)動(dong)(dong)力(li)的主要部(bu)件。作為單點驅動(dong)(dong)方式來講，可(ke)分(fen)成單滾(gun)(gun)(gun)筒(tong)(tong)(tong)傳(chuan)(chuan)動(dong)(dong)及雙(shuang)(shuang)滾(gun)(gun)(gun)筒(tong)(tong)(tong)傳(chuan)(chuan)動(dong)(dong)。單滾(gun)(gun)(gun)筒(tong)(tong)(tong)傳(chuan)(chuan)動(dong)(dong)多(duo)用(yong)(yong)于功(gong)率不(bu)太大(da)的輸送機(ji)(ji)上，功(gong)率較大(da)的輸送機(ji)(ji)可(ke)采用(yong)(yong)雙(shuang)(shuang)滾(gun)(gun)(gun)筒(tong)(tong)(tong)傳(chuan)(chuan)動(dong)(dong)，其特點是(shi)結構(gou)緊湊，還可(ke)增加圍包角以增加傳(chuan)(chuan)動(dong)(dong)滾(gun)(gun)(gun)筒(tong)(tong)(tong)所能傳(chuan)(chuan)遞(di)的牽引(yin)力(li)。使(shi)用(yong)(yong)雙(shuang)(shuang)滾(gun)(gun)(gun)筒(tong)(tong)(tong)傳(chuan)(chuan)動(dong)(dong)時可(ke)以采用(yong)(yong)多(duo)電(dian)機(ji)(ji)分(fen)別(bie)傳(chuan)(chuan)動(dong)(dong)，可(ke)以利用(yong)(yong)齒(chi)輪(lun)傳(chuan)(chuan)動(dong)(dong)裝置(zhi)使(shi)兩滾(gun)(gun)(gun)筒(tong)(tong)(tong)同速運(yun)轉(zhuan)。如雙(shuang)(shuang)滾(gun)(gun)(gun)筒(tong)(tong)(tong)傳(chuan)(chuan)動(dong)(dong)仍不(bu)需要牽引(yin)力(li)需要，可(ke)采用(yong)(yong)多(duo)點驅動(dong)(dong)方式。
