dc.description.abstractThis experimental study addresses grease replenishment mechanisms under varying oscillation amplitudes for deep groove ball bearings with different cage structures. This is complemented by an optical elastohydrodynamic lubrication tribometer. Thereby, three distinct lubrication mechanisms are identified. At small amplitudes, lubrication of the contact area is primarily determined by the lubricant supply from the grease side bands. Under medium-amplitude conditions, interaction between the cage and the side bands on the rolling elements substantially enhances lubrication. At large amplitudes, when the rolling track on the rolling elements connects both the inner and outer rings, grease flow between the rings emerges as a dominant mechanism, effectively reducing wear.
