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)(dong)滾(gun)(gun)筒(tong)是帶(dai)式(shi)(shi)輸(shu)(shu)送機(ji)傳(chuan)(chuan)動(dong)(dong)(dong)動(dong)(dong)(dong)力的(de)主要部件(jian)。作(zuo)為單點(dian)驅動(dong)(dong)(dong)方式(shi)(shi)來講，可分成(cheng)單滾(gun)(gun)筒(tong)傳(chuan)(chuan)動(dong)(dong)(dong)及雙(shuang)滾(gun)(gun)筒(tong)傳(chuan)(chuan)動(dong)(dong)(dong)。單滾(gun)(gun)筒(tong)傳(chuan)(chuan)動(dong)(dong)(dong)多用(yong)于功率不太大(da)的(de)輸(shu)(shu)送機(ji)上，功率較(jiao)大(da)的(de)輸(shu)(shu)送機(ji)可采用(yong)雙(shuang)滾(gun)(gun)筒(tong)傳(chuan)(chuan)動(dong)(dong)(dong)，其特點(dian)是結構緊湊，還可增加(jia)圍包角(jiao)以(yi)(yi)增加(jia)傳(chuan)(chuan)動(dong)(dong)(dong)滾(gun)(gun)筒(tong)所能傳(chuan)(chuan)遞(di)的(de)牽(qian)引力。使用(yong)雙(shuang)滾(gun)(gun)筒(tong)傳(chuan)(chuan)動(dong)(dong)(dong)時可以(yi)(yi)采用(yong)多電機(ji)分別(bie)傳(chuan)(chuan)動(dong)(dong)(dong)，可以(yi)(yi)利用(yong)齒輪傳(chuan)(chuan)動(dong)(dong)(dong)裝置使兩滾(gun)(gun)筒(tong)同速運(yun)轉(zhuan)。如(ru)雙(shuang)滾(gun)(gun)筒(tong)傳(chuan)(chuan)動(dong)(dong)(dong)仍不需要牽(qian)引力需要，可采用(yong)多點(dian)驅動(dong)(dong)(dong)方式(shi)(shi)。
