WIND TURBINES – Effect of Lubricant Properties and Contact Conditions on False Brinelling Damage

PCS instruments: HFRR
Summary: The paper studies false brinelling, a wear type in bearings under small oscillations. It shows that low-viscosity lubricants, lower pressures, and lower frequencies reduce damage when oscillation amplitude is smaller than the contact width. Damage starts at asperities and spreads. Good lubricant flow—not film thickness—helps most under these conditions
