滾(gun)筒(tong)(tong)(tong)分(fen)驅動滾(gun)筒(tong)(tong)(tong)和(he)改向(xiang)滾(gun)筒(tong)(tong)(tong)。驅動滾(gun)筒(tong)(tong)(tong)是傳遞動力的主要部(bu)件(jian)。分(fen)單滾(gun)筒(tong)(tong)(tong)（膠帶對滾(gun)筒(tong)(tong)(tong)的包角(jiao)為210°～230°）、雙滾(gun)筒(tong)(tong)(tong)（包角(jiao)達350°）和(he)多滾(gun)筒(tong)(tong)(tong)（用于大功率）等。
滾(gun)筒(tong)分驅動(dong)滾(gun)筒(tong)和改向滾(gun)筒(tong)。驅動(dong)滾(gun)筒(tong)是傳遞動(dong)力的主要部件(jian)。分單滾(gun)筒(tong)（膠帶(dai)對滾(gun)筒(tong)的包角為210°～230°）、雙滾筒（包角達350°）和多(duo)滾筒（用于大功率）等。
半滾筒的(de)材質(zhi)采用(yong)，以鑄鋼(gang)為主(zhu)，特殊部件采用(yong)優質(zhi)鋼(gang)，根據(ju)使用(yong)情(qing)況，可以用(yong)45M，20LMT.可以保(bao)證使用壽命，為了成(cheng)本降低，機(ji)械(xie)廠采用批量生產。
