Based on the analysis of the relationship between the colloid and rheology of the grease and the vibration and noise of the bearing, the changes of several key factors that affect the vibration and noise of the grease bearing are summarized to affect the vibration and noise performance of the bearing. The rules are summarized as follows: 1. The effect of thickener type on bearing vibration noise; 2. The effect of base oil viscosity on bearing vibration noise; 3. The effect of dynamic oil separation performance on bearing vibration noise; 4. The apparent viscosity Influence of bearing vibration noise; 5. Influence of thickener fiber structure and shape on bearing vibration noise.
