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)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)滾(gun)筒(tong)(tong)(tong)(tong)是(shi)帶式(shi)輸(shu)送機(ji)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)動(dong)(dong)(dong)(dong)(dong)(dong)力(li)的主要部件。作為單(dan)點(dian)驅(qu)動(dong)(dong)(dong)(dong)(dong)(dong)方式(shi)來講，可(ke)(ke)分(fen)成單(dan)滾(gun)筒(tong)(tong)(tong)(tong)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)及雙滾(gun)筒(tong)(tong)(tong)(tong)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)。單(dan)滾(gun)筒(tong)(tong)(tong)(tong)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)多(duo)(duo)用(yong)于功率(lv)不太大(da)的輸(shu)送機(ji)上，功率(lv)較大(da)的輸(shu)送機(ji)可(ke)(ke)采用(yong)雙滾(gun)筒(tong)(tong)(tong)(tong)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)，其特點(dian)是(shi)結構緊湊，還可(ke)(ke)增加圍包角以增加傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)滾(gun)筒(tong)(tong)(tong)(tong)所能傳(chuan)(chuan)(chuan)(chuan)遞的牽(qian)引(yin)力(li)。使用(yong)雙滾(gun)筒(tong)(tong)(tong)(tong)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)時(shi)可(ke)(ke)以采用(yong)多(duo)(duo)電機(ji)分(fen)別傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)，可(ke)(ke)以利用(yong)齒輪傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)裝(zhuang)置使兩滾(gun)筒(tong)(tong)(tong)(tong)同(tong)速(su)運轉。如(ru)雙滾(gun)筒(tong)(tong)(tong)(tong)傳(chuan)(chuan)(chuan)(chuan)動(dong)(dong)(dong)(dong)(dong)(dong)仍(reng)不需要牽(qian)引(yin)力(li)需要，可(ke)(ke)采用(yong)多(duo)(duo)點(dian)驅(qu)動(dong)(dong)(dong)(dong)(dong)(dong)方式(shi)。
