滾(gun)(gun)(gun)筒(tong)(tong)(tong)分驅動滾(gun)(gun)(gun)筒(tong)(tong)(tong)和(he)改向(xiang)滾(gun)(gun)(gun)筒(tong)(tong)(tong)。驅動滾(gun)(gun)(gun)筒(tong)(tong)(tong)是傳(chuan)遞動力的主(zhu)要(yao)部件(jian)。分單滾(gun)(gun)(gun)筒(tong)(tong)(tong)（膠帶對(dui)滾(gun)(gun)(gun)筒(tong)(tong)(tong)的包角為210°～230°）、雙滾(gun)(gun)(gun)筒(tong)(tong)(tong)（包角達350°）和(he)多(duo)滾(gun)(gun)(gun)筒(tong)(tong)(tong)（用于大功率）等。
滾(gun)筒分驅動滾(gun)筒和改(gai)向(xiang)滾(gun)筒。驅動滾(gun)筒是傳遞動力的主要部件(jian)。分單滾(gun)筒（膠帶對滾(gun)筒的包(bao)角(jiao)為210°～230°）、雙滾筒（包(bao)角(jiao)達350°）和多滾筒（用(yong)于大功率）等。
半(ban)滾筒的材質采(cai)用(yong)，以(yi)鑄鋼為主，特殊部(bu)件采(cai)用(yong)優(you)質鋼，根據使用(yong)情(qing)況，可以(yi)用(yong)45M，20LMT.可(ke)以保證(zheng)使(shi)用壽命，為了(le)成本降低，機械廠采用批量生產。
