Using Thermography to Uncover Hidden Problems

The combined motor to gearbox and gearbox to mill drive pinion misalignments resulted in a loss of end float within the gearbox, trapping the intermediate shaft gear. The 10.3-degree C temperature difference across the mill drive pinion gear was also considered excessive and indicative of severe pinion to girth gear misalignment.
