fig. 5 illustrates the pinion temperature distribution of a gear set having optimum alignment. the temperature gradient. which is the temperature at position 1 minus the temperature at position 5, is zero indicating that the load int,ensity is the same on both ends of th pinion. position 1 is taken toward the mill end of the pinion face.
the mill drive system consists of the main mill motor, the main reduction gear box, mill pinion and girth gear. the mill is also equipped with a barring drive, which is either connected to the main drive reduction unit or, alternatively mounted at the back of the main motor. refer to figure 3 for a schematic of the mill drive system.
