I have an issue with a gear drive on a ball mill. 2XGM is rising and i have sidebands at 107cpm and I don't know why they are at 107 (not relevant to any turning speeds ect.) I checked the root clearance a week ago and the inboard is about a .066 smaller than the outboard. The pinion is 24" long and has 24 teeth. It is obvious i have misalignment.And there is obvious spalling …

transmitting the vibration energy across the bull gear to the other pinion. This is a good example of how the vibration of one pinion can act as a source of vibration on a separate pinion. The lateral transmissibility of a gear train is dependent on the design of the pinion and bullgear geometry, gear teeth geometry,

The drive of the ball mill consists of an induction electric motor, two-stage gearbox and the pinion gear. This pinion gear is mated with the girth gear mounted on circumference of the ball mill shell and in that way it transfers the motion from the drive to the shell, see Figure 1, taken from [1].
