The pinion from the drive of the cement mill was failed; the teeth cracked and spall occurred on the sides of several teeth. The failure was only located on one side of the pinion. This type of failure is common with surface-hardened gears.
Three things can cause a vibration here: a bad U joint, a bad center bearing, or a differential problem. I suppose you could also say the driveshaft itself, but I would put this at the very bottom of my suspect list and eliminate the previous three first. As with FWD vibration problems, it's really a …
By applying the lubricating grease we will prevent from a quick wear of the teeth of the crown and pinion. A correct lubrication will increase fatigue resistance, will minimize noises and vibrations and will prevent early cracks. Pitting and micropitting problems of the metal surfaces will also be prevented

As such you will find it is designed and constructed according to heavy duty specifications.
On the outside, horizontal grinding mills often face the elements. On the inside, they endure vibration, shock loads, moderate to slow speeds, and a high concentration of particulates. It's a harsh, potentially costly combination. Contamination, lubricant loss, even improper mounting techniques can all lead to failures for pinions or trunnion.
and vibration damping to limit the transmission of vibration to the nearby buildings. In the following years some mills have been fitted with these devices while others have not. It is a decision to be made every time a new mill is designed and is driven by the characteristics of the soil. Buzzi Unicem have mills that are fitted with
the inboard pinion bearing from readings taken on 5, 18, and 19 May (Figure 2). This identification using conventional vibration data occurred considerably later than the initial revelation of the problem by PeakVue. Note that the vibrations returned to normal on 3 June after the repair completed on 1 June. Multiple waveform views (Figure 3)
