Rolling mill consisting of three rolls or known as 3 High rolling mill is typically used for performing multiple reduction passes by wrapping material around the center mill roll and performing another reduction on the opposite mill roll pair. 3 High mill can also be used with varying mill roll sizes to induce a specific percentage of reduction of material on a single side of the work piece ...
Gear reducers utilize double or triplereduction gearing; Fig. shows a schematic of the most popular doublereduction unit. It contains three shafts: the highspeed input shaft, an intermediate shaft, and a slowspeed shaft. The highspeed shaft is driven by the prime mover through a Vbelt sheave, and the slowspeed shaft drives the crank arms of the pumping unit.
