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)(gun)(gun)筒(tong)(tong)是(shi)(shi)帶式(shi)輸(shu)送機傳(chuan)動(dong)(dong)(dong)(dong)動(dong)(dong)(dong)(dong)力(li)的(de)(de)主要(yao)部件(jian)。作為單(dan)(dan)點(dian)(dian)驅(qu)(qu)動(dong)(dong)(dong)(dong)方式(shi)來講，可分(fen)(fen)成單(dan)(dan)滾(gun)(gun)(gun)(gun)(gun)筒(tong)(tong)傳(chuan)動(dong)(dong)(dong)(dong)及(ji)雙滾(gun)(gun)(gun)(gun)(gun)筒(tong)(tong)傳(chuan)動(dong)(dong)(dong)(dong)。單(dan)(dan)滾(gun)(gun)(gun)(gun)(gun)筒(tong)(tong)傳(chuan)動(dong)(dong)(dong)(dong)多(duo)用(yong)于功(gong)率(lv)不(bu)(bu)太大的(de)(de)輸(shu)送機上，功(gong)率(lv)較(jiao)大的(de)(de)輸(shu)送機可采用(yong)雙滾(gun)(gun)(gun)(gun)(gun)筒(tong)(tong)傳(chuan)動(dong)(dong)(dong)(dong)，其(qi)特點(dian)(dian)是(shi)(shi)結構(gou)緊(jin)湊，還可增(zeng)加圍包(bao)角以增(zeng)加傳(chuan)動(dong)(dong)(dong)(dong)滾(gun)(gun)(gun)(gun)(gun)筒(tong)(tong)所能傳(chuan)遞的(de)(de)牽(qian)引力(li)。使(shi)用(yong)雙滾(gun)(gun)(gun)(gun)(gun)筒(tong)(tong)傳(chuan)動(dong)(dong)(dong)(dong)時可以采用(yong)多(duo)電機分(fen)(fen)別傳(chuan)動(dong)(dong)(dong)(dong)，可以利(li)用(yong)齒(chi)輪傳(chuan)動(dong)(dong)(dong)(dong)裝置使(shi)兩滾(gun)(gun)(gun)(gun)(gun)筒(tong)(tong)同速運轉。如(ru)雙滾(gun)(gun)(gun)(gun)(gun)筒(tong)(tong)傳(chuan)動(dong)(dong)(dong)(dong)仍不(bu)(bu)需(xu)要(yao)牽(qian)引力(li)需(xu)要(yao)，可采用(yong)多(duo)點(dian)(dian)驅(qu)(qu)動(dong)(dong)(dong)(dong)方式(shi)。
