Ball Mill Pinion Vibration Analysis & Machinery

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 on the gear faces

Four Common Faults of Rod Mill and Their Solutions!

During the installation, some errors exist in the flatness and parallelism among the rod mill barrel, motor, reduction gear and pinion base. When the rod mill runs, the vibration of the transmission system causes pinion and bearing to be subjected to impact load, accelerates wear, and even causes the pinion
