正常運(yun)轉(zhuan)(zhuan)時，帶(dai)速不低于輥(gun)筒(tong)(tong)轉(zhuan)(zhuan)速的(de)95%。如(ru)果輥(gun)筒(tong)(tong)與(yu)輸(shu)(shu)送(song)帶(dai)的(de)摩(mo)擦(ca)(ca)力不夠，輸(shu)(shu)送(song)帶(dai)就容易出現打(da)滑的(de)現象(xiang)。引起(qi)輥(gun)筒(tong)(tong)與(yu)輸(shu)(shu)送(song)帶(dai)摩(mo)擦(ca)(ca)力不夠的(de)原(yuan)因很多(duo)，常見的(de)有：張力不夠、載荷啟動、輥(gun)筒(tong)(tong)表面摩(mo)擦(ca)(ca)系數不夠等。
